Fulton characterizes the multiplicity I(E∩F) with seven properties (§3.3). (Fulton calls it the intersection number. Also, he writes I(P,E∩F) for the intersection number at P. I'll usually assume P is the origin O, and omit writing it.) The last three properties stand out:
- I(E∩F) ≥ m(E)m(F), with equality if and only if E and F have no tangent lines in common. Here m(E) and m(F) are the multiplicities of E and F (explained below). As Fulton notes, all we really need is a much weaker property: I(x∩y)=1. That is, the lines x=0 and y=0 (the axes) intersect with multiplicity 1 at the origin.
- I(E∩FG) = I(E∩F) + I(E∩G).
- I(E∩F) = I(E∩(F+AE)) for any polynomial A.
The multiplicity of a curve at the origin O is the order of its polynomial, i.e., the degree of its lowest order term(s). Take our favorite E and F:
The multiplicity (at O) of E is 3, and of F is 4. We know from the pictures in the first post that E has three distinct branches at O, and F has four. Intuitively, property (5) says that every intersection of a branch of E with a branch of F contributes 1 to the intersection number when the branches intersect transversally, and more than one if they are tangent.
Property (6) seems obvious once you notice that FG=0 defines the union of the curves F=0 and G=0. Of course, F and G might have a common factor—a common component of the two curves. Property (6) then says that the component counts double when intersecting E with FG.
Fulton calls property (7) "the least intuitive". Let's see if the "level curve" idea sheds any light. Recall how this works: we parametrize a branch of E as (xE(t), yE(t)), passing through O when t=0; xE(t) and yE(t) are power series in t. We plug (xE(t), yE(t)) into the polynomial F(x,y), obtaining a function F(t). The order of F(t) gives the multiplicity of the branch-curve intersection.
Now, E is the level curve E(x,y)=0, and (xE(t), yE(t)) moves along a branch of it, so E(t)=E(xE(t), yE(t)) is identically zero. So
(F+AE)(t) = F(t)+A(t)E(t) = F(t)
So the order is the same for both F and F+AE, all branch-curve intersections have the same multiplicity, and therefore the curve-curve multiplicity is the same.
As Fulton notes, the seven properties imply an algorithm for computing intersection numbers. Fulton illustrates it for our favorite curves E and F (see p.40), incorporating some shortcuts. Let's see how it goes. He uses some auxiliary curves:
Here's the strategy: use property (7) to whittle down the higher-order part. For E, this is (x2+y2)2, and for F it is (x2+y2)3, so forming F′ = F–(x2+y2)E cancels it out. We're lucky that F′ factors as yG. Note the total degrees of F, F′, and G: 6, 5, 4.
We can't use (7) to reduce the total degree of G, so instead we target the degree of the x-part—what we get by striking out all terms involving y, i.e., G(x,0). This is –3x4. So we form G′ = G+3E (because the x-part of E is x4). Now we are lucky that G′ factors as yH.
The auxiliary curves G and H look like this:
Recall that F, the four-petal rose, has two branches tangent to the x-axis at O. G has only one, and H has none. Note that we remove a factor of y passing from F′ to G, and from G′ to H.
The full computation of I(E∩F) looks like this:
I(E∩F) = I(E∩F′) = I(E∩yG), by (7)
I(E∩yG) = I(E∩y) + I(E∩G), by (6)
I(E∩G) = I(E∩G′) = I(E∩yH), by (7)
I(E∩yH) = I(E∩y) + I(E∩H), by (6)
I(E∩H) = m(E) m(H) = 3×2 = 6, by (5)
I(E∩y) = I(x4∩y), by (7)
I(x4∩y) = m(x4) m(y) = 4×1, by (5)
I(E∩F) = I(E∩y) + I(E∩y) + I(E∩H) = 4+4+6 = 14
—the same result we've seen before.
I'll look at Fulton's other definition in Post 7.


tst', 'prd']
 }

 var mainStorageAccountName = 'stor${environmentName}main'
 var otherStorageAccountName = 'stor${environmentName}other'
 var somethingWebAppName = 'webappp${environmentName}something'

As you can see, the values for the three variables are now much easier to read. Readability is greatly enhanced because it is no longer needed to call to the parameters(...) function in combination with the ${...} syntax. As a bonus, when you are using the Bicep extension for VS Code – syntax highlighting also shows where string interpolation is used to enhance readability even more.
No mandatory grouping
One of the consequences of using JSON as the basis of ARM Templates was the object notation for parameters and variables. Through this choice, all parameters and variables have to be grouped in one location of a template – usually at the start. Take a look at the following example:

 {
 "$schema": "_URL_
 [CA] 2019-04-01/deploymentTemplate.json#",
 "contentVersion": "1.0.0.0",
 "parameters": {
 "environment": { #B
 "type": "string"
 },
 #A
 },
 "variables": {
 "webAppPlanName": "[format('myAppPlan-{0}', parameters('environment'))]",
 "anotherVariable": "someValue"
 },
 "resources": [
 #A
 {
 "type": "_URL_",
 "apiVersion": "2020-06-01",
 "name": "[variables('webAppPlanName')]", #C
 "location": "westeurope"
 }
 ]
 }

#A Imagine there are tens or hundreds of lines at these locations
#B The declaration of a variable
#C The usage of that same variable
Especially in larger templates, this made for much scrolling up and down, as parameters were all defined at the top and used much more down in the file. JSON provides no way to work around this, and you cannot declare the parameter or variable keys more than once. With the new Bicep syntax, the grouping of parameters at the top is no longer necessary, and you can do something like this.

 param environment string = 'tst'

 #A

 var webAppPlanName = 'myAppPlan-${environment}' #B

 resource myWebApp '_URL_ protected]' = {
 name: webAppPlanName #C
 location: 'westeurope'
 }

 #A

 var anotherVariable = 'someValue'

 #A

#A Imagine there are tens or hundreds of lines at these locations
#B The declaration of a variable
#C The usage of that same variable
In this example, you see that parameters and variables are now declared just before they are used. Other variables can be declared where they are used without problems. Strictly speaking, you can even use variables before they are used as everything is eventually grouped anyhow when transpiling to an ARM template.
All of this greatly enhances both the readability and understandability of the templates.
Comments
A final improvement of the Bicep language is the introduction of comments. While ARM Templates already supports comments, this has one downside: it makes the templates no longer JSON-compliant. This leads to many text editors pointing to comments as an error. Luckily, VS Code is an exception to that rule as it understands ARM templates instead of "just" JSON. With Bicep, all of this no longer applies, and you can now use comments as follows.

 var webAppPlanName = 'myAppPlan' // Everything after a double slash is a comment

 resource myWebAppPlan '_URL_ protected]' = {
 name: webAppPlanName
 location: 'westeurope'
 /*
 Using slash star you can start a multi-line comment
 Star slash closes the comment
 */
 }

In this example, there are two types of comments. A single-line comment is added using a // at (the end of) every line. A multi-line comment is created by enclosing it in /* and */. It is unnecessary to put the /* and */ on a line of their own, but it is the convention.

Arduino Sensors
Lesson 4
Detect tilt and impact
In many cases, knowing the exact force and direction applied to our gadgets is an overkill; just knowing that a bottle has been tipped over is enough to know that the lid should close automatically. For simple cases like that, a 3-axis accelerometer is an overkill. We could use a simple sensor that can detect the shock of an impact or for being upside down.
Tilt and impact sensor
The tilt and impact sensor is a simple switch which closes a circuit when positioned in a particular way. They are very cheap, around $5 on eBay for a pack of 10. They come in a variety of shapes, but usually they are made of a tiny metallic cylinder with a thin copper wire coming out of one end.
The cylinder contains wires or a metal ball. When the device is hit or when its orientation changes, the wires or the ball come in contact with the wall of the cylinder and closes a circuit between the cylinder and the external wire.
They can be very sensitive, so care must be given to compensating for this sensitivity, otherwise we would be getting readings that look chaotic. We are going to ignore this sensitivity for now.
Here is what a tilt sensor looks like from the outside…
Cylindrical tilt and impact sensor
... and on the inside.
Assembly
To put this circuit together, we'll just use the Arduino, no breadboard is required.
We need to do a bit of soldering in order to connect the sensor to wires which we can connect to the Arduino. If you have never done soldering before, follow this tutorial for some instructions. Be careful not to get burned!
Here's what we are going to build.
Connect one wire to 5V and the other wire to A0 analog pin
Sketch
This is another very simple sketch. We'll just use the analog pin to determine if the switch inside the sensor is closed or open. You could just as easily have used a digital pin since there are only two states to detect, open or close, which nicely translate to HIGH or LOW.

int out;

{
 Serial.begin(9600); // sets the serial port to 9600
}
void loop()
{
 out = analogRead(0); // read analog input pin 0
 Serial.println(out, DEC);
 delay(100); // wait 100ms for next reading
}
Try out by connecting the sensor to the Arduino and moving the sensor in different directions. This is easier if you use some electrical tape to keep the sensor wires tidy. You could even stick the sensor onto the Arduino, and move the whole assembly instead of only the sensor. This will help in keeping the connections firm.

Halo Alpha
Halo Alpha
CMA Arabia was a Charon-class light frigate under the command of the Colonial Military Administration.
Operational History[]
Arabia was part of Battlegroup 4 led by Captain Veredi of CMA Heracles that was sent to Harvest to find out what happened to the scout ship CMA Argo and Harvest. The battle group consisted of the destroyer CMA Heracles and the frigates Arabia and CMA Vostok. They were sent to discover the fate of the colony on the planet Harvest, where contact had recently been lost with the local populace. The battle group encountered a Covenant vessel holding station in Harvest orbit and Arabia was destroyed almost instantly by the Covenant's superior firepower. All hands were lost aboard the vessel.[1][3]
Its partner ship, Vostok, was destroyed at the same time and Heracles was forced to retreat after sustaining heavy damage.
The CMA Arabia had one meter of armor plating.[2]

Is RV Antifreeze Toxic On Your Skin? Everything You Need To Know
As an outdoor enthusiast, you may be familiar with RV antifreeze, a solution that is commonly used to winterize recreational vehicles (RVs) to prevent plumbing and water lines from freezing during colder months. While RV antifreeze is an essential component of winterizing an RV, it is crucial to be aware of its potential toxicity on the skin.
In the following sections, we'll delve deeper into the composition of RV antifreeze, its potential toxicity on the skin, the safe handling of RV antifreeze, alternative options to RV antifreeze, and the importance of staying informed about the risks associated with using RV antifreeze.
Let's dive right in.
Understanding RV Antifreeze
Before we discuss the potential toxicity of RV antifreeze on the skin, it's essential to understand what RV antifreeze is and how it works.
RV antifreeze is a solution that is specifically designed to prevent water lines and plumbing in RVs from freezing during colder months. There are two main types of RV antifreeze: ethylene glycol-based antifreeze and propylene glycol-based antifreeze.
Ethylene glycol-based antifreeze is the traditional type of RV antifreeze and is commonly used in colder climates. It is a highly toxic substance that is known to be harmful to humans, animals, and the environment. As such, it is crucial to handle this type of antifreeze with extreme care to avoid any adverse health effects.
Propylene glycol-based antifreeze, on the other hand, is a less toxic alternative to ethylene glycol-based antifreeze. While it is still not completely non-toxic, it is generally considered safer than ethylene glycol-based antifreeze and is often used in milder climates.
Regardless of the type of RV antifreeze used, it works by lowering the freezing point of water, allowing it to flow freely through the RV's plumbing without freezing. This is achieved by adding a chemical compound that is designed to bond with water molecules and prevent them from freezing.
It's important to note that RV antifreeze is not the same as automotive antifreeze, which is not safe for use in RVs due to its high toxicity levels. Always make sure to use RV-specific antifreeze when winterizing your RV.
In the next section, we'll discuss the potential toxicity of RV antifreeze on the skin and the best practices for staying safe when handling it.
Potential Toxicity of RV Antifreeze on the Skin
While RV antifreeze is typically labeled as non-toxic, it is important to understand that both ethylene glycol-based and propylene glycol-based antifreeze can be harmful if they come into contact with the skin. In this section, we'll discuss the potential toxicity of RV antifreeze on the skin and the best practices for staying safe when handling it.
Ethylene glycol-based antifreeze is highly toxic and can cause severe health problems if ingested or absorbed through the skin. Exposure to ethylene glycol-based antifreeze can cause skin irritation, blistering, and chemical burns, especially if left on the skin for an extended period.
Propylene glycol-based antifreeze, on the other hand, is less toxic than ethylene glycol-based antifreeze, but it can still cause skin irritation, redness, and itchiness if it comes into contact with the skin. In addition, inhaling the vapors of propylene glycol-based antifreeze can cause respiratory irritation and other respiratory problems.
Next, we'll discuss how you can handle RV Antifreeze in a manner that is safer and more environmentally friendly.
Safe Handling of RV Antifreeze
Now that we've discussed the potential toxicity of RV antifreeze on the skin, it's important to know how to handle it safely. In this section, we'll outline some best practices for safe handling of RV antifreeze.
1. Read the Label
Before handling RV antifreeze, make sure to read the label carefully. The label will provide important information on the type of antifreeze, any potential hazards, and recommended safety precautions. Follow the instructions and recommended safety precautions closely to avoid any risks associated with handling the product.
2. Wear Protective Gear
As we mentioned in the previous section, it's crucial to wear gloves and protective clothing when handling RV antifreeze. Make sure to choose gloves that are chemical-resistant and made of a material like nitrile or neoprene.
Additionally, wear a long-sleeved shirt and pants made of a synthetic material like polyester or nylon to reduce skin exposure.
3. Use Proper Tools
When transferring RV antifreeze from its container to your RV's plumbing system, use a funnel or other appropriate tool to avoid any spills or splashes. Make sure the funnel or tool is clean and free of any contaminants before use.
4. Store Properly
When not in use, store RV antifreeze in its original container and in a cool, dry place away from direct sunlight. Make sure the container is sealed tightly to prevent any leaks or spills.
5. Dispose of Properly
When disposing of used RV antifreeze, do not pour it down the drain or into the environment. Check with your local waste management facility for instructions on proper disposal. Many facilities offer a recycling program for used antifreeze, so take advantage of these programs to reduce environmental impact.
By following these best practices for safe handling of RV antifreeze, you can reduce your risk of exposure and avoid any potential health risks associated with handling the product.

Conclusion – Is RV Antifreeze Toxic on Your Skin?
RV antifreeze can be toxic on your skin if proper safety precautions are not taken during handling. It's important to wear protective gear, use proper tools, and avoid any skin contact.
Remember to always read the label and follow recommended safety precautions when handling RV antifreeze. If you do come into contact with RV antifreeze on your skin, immediately wash the affected area with soap and water and seek medical attention if necessary.

Should there be a right to a radio aid?Published Date: 08 Oct 2018
Everyday life can be busy and noisy with family gatherings, trips out to playgrounds and activity centres and frequent journeys in the car and the buggy. Having two children myself I know how loud we all can be particularly when my six siblings and their children come round. In fact recent research indicates that young children can spend up to 25% of their day in noisy environments. So knowing what we know about how important it is for young children to hear spoken language in order to develop good communication and language and how babies have to learn how to be good listeners, why can't all deaf pre-school children be considered for a radio aid at the same time as they are fitted for a hearing aid?
We think every family should have the right to try a radio aid, from an early age, so they can see if it would work well for them. Our research shows that it can have big benefits. If you would like to try one, you can talk to your audiologist and Teacher of the Deaf about radio aids. As soon as your child has hearing aids or a cochlear implant, discuss options with your Teacher of the Deaf about trying out a radio aid at home. It may take some getting used to and you don't need to use it all the time, but when you think about the times your child is in a noisy place or behind you in the car, it will be then that your child could really benefit from hearing your voice clearly.
So here are some things you may want to consider when using a radio aid with a baby or toddler.
- Think about the best time to use the radio aid for you and your child, it may be in the car, when you are sharing a book with a sibling, or playing with your child at toddler group. Take a look at this short video to see how a family used a radio aid to help communication.
- All the family can use the radio aid, so pass it around when another family member is interacting with your child
- Radio aids use up battery power so you will need to change the batteries in your child's hearing aids more frequently
- Place the microphone carefully. About 15cm from your mouth is best and avoid wearing anything that will knock against it as the sound will travel straight into your child's ears.
- Don't forget to use the mute button, there are some conversations your child doesn't need to hear.
Unfortunately, radio aids are not always available for use in the home or for pre-school deaf children. We're campaigning for them to be more widely available – local authorities will need to ensure that services have the resources to fund, maintain and monitor the equipment.
Remember the best communication happens in a quiet environment, when you are close to you child, they can see your face and you are sharing experiences, but when this isn't possible consider trying a radio aid. If you'd like more information about radio aids, take a look at our website.

Storage and use
The volume of surface water used in the Northern Territory (NT) each year is roughly 50,000 megalitres.
You need a licence to take or use surface water. Read how to apply for a surface water extraction licence.
Surface water uses are divided into the following:
- 75% urban
- 12% irrigation
- 6% pastoral
- 5% rural
- 2% mining or other.
Storage of surface water
Surface water is stored in dams, farm dams, excavated tanks, turkey nests or steel tanks.
Large surface water storages are used for water supply, recreation or flood control.
The three major dams in the NT are Darwin River Dam, Manton Dam and Mary Anne Dam.
There are only two major water supply systems that use surface water in the NT.
These are Darwin's water supply from the Darwin River Dam and Katherine's water supply from the Donkey Camp weir on the Katherine River.

How to Care for Crocodile Skin Leather Goods
Crocodile goods are very famous as well as expensive. These goods are costly because of fine quality crocodile leather. Different things are made with this high-priced leather-like, shoes, bags, coats and violet etc. These things come with great responsibility because it is very easy to buy and wear them but on the other hand, very difficult to save them. Here are some ways to safe these products for a long time.
1. Avoid from the direct sun:
The leather of crocodile is very fine and also transformed in many ways. So after made it as a final product, it became finer and dry. If you put this product to direct sunlight then it becomes dry out. Heat will cause damage and also a loss of natural sheen. So avoid direct heat and put these things in a closet to keep them dry and good.

2. Keep safe from rain and water:
Some leathers are able to absorb the water but others are not. If this leather absorbs water, in that case, your product could be damaged. So, avoid unnecessary water usage on it. While washing your product use excess water. The better way is to use your thing and then put it back without washing. Use a dry cloth for rubbing the surface. Also, spray and creams are coming along with these products so use them only. The skin of crocodile is already moisture so any water can cause to damage the product.
3. Keep away from harsh chemicals:
Do not use the chemical to wash these products. Use chemicals that are written in the catalog of these leather products. Do not spray any kind of perfume on it. Especially when you are wearing a jacket, take care of it while eating.
4. Do not scratch the surface:
If you get some dirt or stain on it, do not scratch it because it causes breaks in the leather and it cannot be repaired. So only clean the main area and use conditioner and let it dry.

5. Avoid folding and pressing opposite to its real shape:
For a longer use of crocodile leather pieces, for example, if you have a leather jacket, avoid folding it tightly. Because first of all, crocodile skin is caiman skin and it has calcium stores in it that makes crocodile skin more rigid. If you start folding the skin tightly then it comes to at points where not need to be folded then it might cause damage. And the result could be more horrible like unsightly cracks or wrinkle marks.
By all means, when the client gets his custom-made crocodile skin product, he became responsible to take care of it. With the proper care of crocodile skin products, it should stay beautiful and fresh. These are always ready for use even for many years. We are sharing these general care tips and these tips are more important for the crocodile leather products. With this, you can help to extend the useful life of expensive and exotic leather goods. These tips keep the clients satisfied and coming back for more goods.

IXTENCO, Mexico — On the slopes of the Malinche volcano, Juan Vargas starts the dawn routine he's had since childhood, carefully checking stalks of colorful native corn. For years, Vargas worried that these heirloom varieties — running from deep red to pale pink, from golden yellow to dark blue — passed down from his parents and grandparents would disappear. White corn long ago came to dominate the market and became the foundation of Mexicans' diet.
But now, the heirloom corn Vargas grows is in vogue. It accounts for 20 of the 50 acres on his farm in Ixtenco, in the central state of Tlaxcala. Vargas, 53, remembers just one acre reserved for it 2010, when demand was virtually zero and prices low. Fueled largely by foreign demand, the corn in its rainbow of colors has become more profitable for him than the white variety.
Vargas is among farmers in Mexico who've been holding on to heirloom strains for generations, against a flood of industrially produced white corn. They're finding a niche but increasing market among consumers seeking organic produce from small-scale growers and chefs worldwide who want to elevate or simply provide an authentic take on tortillas, tostadas and other corn-based pillars of Mexican food.
Corn is the most fundamental ingredient of Mexican cuisine, and it's never far from the national conversation. Amid President Andrés Manuel López Obrador's move to ban the importation of genetically modified corn and his imposition of a 50% tariff on imported white corn, some scientists, chefs and others are advocating for the value of the old varieties in an increasingly drought-stricken world.
Heirloom varieties make up far less than 1% of total domestic corn production in Mexico. But for the first time in years, Vargas and others are hopeful about the crop. Some in the academic and public sectors hope to increase its production.
Vargas' heirloom corn sells for around $1.17 per kilogram abroad, more than three times the price for his white. If demand keeps growing, he'll plant more. He boasts about his colorful "little corn" that travels the globe.
"People abroad validated us," he said.
In Brooklyn, Mexican chef Zack Wangeman and his wife, Diana, have been running their tortilla shop and restaurant, Sobre Masa, since 2021. Their dishes and corn masa, which they sell to other New York restaurants, are made with heirloom Mexican corn from small farms.
Wangeman, 31, believes tortillas made from that corn have gained a foothold because for many they evoke a "country flavor ... that taste of toasted corn" that is uniquely Mexican.
"When you use hybrid corn, genetically modified corn or whatever other option there is, it doesn't give you that nostalgic flavor," said Wangeman, who was born in the southern state of Oaxaca.
He was drawn to the corn by a chef friend who returned from a food fair raving about it. Wangeman got in touch with Tamoa, a company that since 2016 has promoted the heirloom corn grown by about 100 families in central and southern Mexico to foreign markets.
Across Mexico, about 60,000 tons of heirloom corn is produced annually. It's a tiny fraction of the 23 million tons of white corn grown on an industrial scale to meet domestic demand for human consumption and the 16.5 million tons of yellow corn that Mexico imported last year — mostly from the U.S. — for industrial and animal feed use.
It's unclear how much of the heirloom corn goes abroad — Mexico doesn't keep export data for the crop. But Rafael Mier, director of the Mexican Corn Tortilla foundation, said it's clear exports of heirloom corn are growing based on the increasing number of tortillerías and restaurants buying it, especially in the U.S.
In Las Vegas, chef Mariana Alvarado said she began getting native corn through Tamoa and Los Angeles-based Masienda for tortillas, tostadas, tamales and the masa she sells in markets and online about four years ago.
At the time, she said, maybe 20 chefs in the U.S. used native corn — she estimates that's now doubled.
Little by little, Alvarado said, she built a client list of Latinos and fans of Mexican cuisine looking for "organic, clean, healthy food." She doesn't believe this is a passing fad — in fact, she expects the distinction between Mexican food that uses modified corn and more authentic fare made with heirloom strains to grow.
"Smelling them, trying them — they realized that the taste is totally different from the tortillas they were used to here in a supermarket," Alvarado said of U.S. customers.
"We're making noise as tortilla-makers here in the United States, bringing native corn," Alvarado said.

Dynamics of Piecewise Continuous Functions
Siddiqui, Sauleh Ahmad
MetadataShow full item record
In our paper, we explore the chaotic behavior of a class of piecewise continuous functions defined on an interval X in the real line. A function or curve is piecewise continuous if it is continuous at all but a finite number of points and the left and right hand side limits exist at those points. In particular we will be looking at the piecewise continuous function for which the pieces are affine. We will show that show that f is locally eventually onto, has dense periodic points, and has sensitive dependence on initial conditions. We also show that f is quasiconjugate to a shift map of finite type to prove that f is chaotic. While functions such as f are known to be chaotic through proofs developed by measure theory, our paper is unique in that we use topological dynamics to show f is chaotic. Future work may extend these results to other compact metric spaces and more general piecewise continuous functions.

We present the study of the high-energy photon emission by protons and electrons/positrons accelerated by an electric field of a Kerr black hole (BH) in an overcritical magnetic field. Protons can reach energies up to $\sim 10^{21}$ eV. The principal process is synchrotron emission. We calculate the photon emission probability and opacity in order to see whether these photons can escape from the BH site, accounting for the different energies emission detected from GRBs observations. The escaping probability is dictated by the multiple interactions of $e^{+}/p/\gamma$ and EM cascade processes. We calculate all the cross-sections and mean free paths for each process and estimate the total optical depth.

Reconstructing 3D models from their projection images has been an interesting research topic in computer vision and geometric modeling. In this paper, we review several methods that generate octree models of objects from their silhouettes in images. The complexity analysis of the algorithms is developed and presented. It is concluded that the performance of the algorithms depents mostly on the number of starting images and the object shapes through their number of faces and concavities.

The Division focuses on preventive measures for curbing child labour, and trafficking as well as facilitate different rescue operations. The Division is also responsible for tracking of rescued children, their compensation, and the rehabilitative mechanisms. To read the complete mandate of the Division, kindly click here.
Projects and Initiatives
Some of the most prominent projects/initiatives undertaken during Financial Year 2020-21 are mentioned:
1. Rescue of children from Child Labour
The non-wavering commitment of the Commission to eliminate child labour resulted in rescue of 331 children in the year 2020-21 in comparison to a total of 202 children being rescued in the preceding 3 years. Belonging to different age groups, the youngest of the rescued children was 10 years old and were rescued with the help of Sub-Divisional Magistrate (SDM), Delhi Police, Labour Department, ChildLine and Child Welfare Committee (CWC) from different places such as factories, bakery units, kharat machine units and auto center units, as well as residential colonies where the children were working as domestic servants.
2. Rehabilitation of the rescued child labourers
Rescuing children from hazardous employment situations acts as an immediate relief for them but does not guarantee their long-term safety and the chances of them falling back into the clutches of labour remains. Therefore, the Commission ensures end-to-end rehabilitation of the rescued children in the following manner:
- a. Restoration: restoring a child with their parents and family is a critical first step as it gives the child an environment of care and love. The Commission has ensured the restoration of 90% of the rescued children, and is in the process of restoring everyone at the earliest.
- b. Backwages: Compensation for the rescued children under the Child Labour (Prohibition and Regulation) Act, 1986 and Bonded Labour System (Abolition) Act, 1976 has been a consistent challenge, with only 50% of the rescued children having received their back wages.. While CWCs have been doing their job in ensuring that the backwages are retrieved and deposited in the child's account, the interdepartmental coordination has led to consistent bottlenecks. The Commission is apprised of such cases and the concerned officers from the Revenue and Labour department are taken in loop to speed up the process of retrieval.
- c. Enrolment in Schools: By enquiring about the rescued children's enrolment in schools and their families' involvement in different government schemes that might help them with some income, food and other basic necessities ensure that the families children are not pushed into labour. DCPCR has put in efforts to identify the possibility of linking such families to relevant social schemes. 30% of the children rescued from Delhi are not yet enrolled in any education institution, thus the process to counsel them and get them enrolled in the vocational course has been initiated.
3. Stakeholder Investment
The challenge of child labour can only be tackled if there is investment within the system (like Labour department, Revenue department etc) along with the citizens, both adults and children. To sensitize children from the privileged backgrounds about the hardships faced by children who are forced into labour and to encourage them to have conversations about the same within their families, a painting competition was organized with the Private School Association for the same which had some amazing paintings depicting deep insights from the children regarding the cause. The best works were also awarded.
Multiple NGOs were also encouraged to sign a pledge to report any instance of child labour that would come to their notice and also committing that no member in the organization would engage in it at individual level. Similarly, the Chairpersons of the Mandi Associations across Delhi also pledged the same and made visits to ensure that their mandis were child labour free.
4. Intervention to prepare an SoP for child labour rescue operations and common performa for inter-departmental co-ordination
The process of planning and executing rescue operations needs coordination and liaisoning between various departments and stakeholders. Without comprehensive SoP that defines the roles and responsibilities of each stakeholder, there can be breakdowns in the process. The Commission is in the process of preparing a standard operating procedure including a standard format /performa to gather information of the reduced child and offending employers that will better enable inter-departmental coordination and tracking of children till they are rehabilitated.
5. Tracking District Task Force Meeting:
The Commission, in its efforts to plan for preventive strategies for child labour, identified District Task Force meetings as one of the leverages. Being mandated to be held monthly under the CLPRA Amendment Rules, 2017, the Commission started to monitor these meetings and advised the DMs to use these meetings to discuss and plan preventive and proactive interventions along with planning of rescue operations. 12 meetings across 5 districts in the last 6 months have already been conducted despite the challenges of the pandemic.
The Commission is also working with Revenue department to ensure that these meetings include identification of the vulnerable areas, act on pending information of trafficking/child labour, examine the rehabilitation efforts, review processes, and plan forward. The Revenue department and the Labour department are also made aware of Rule 2(b)(2) of the CLPRA Amendment Rules, 2017 which says that information of children who were absent in schools for consecutively 30 days is shared with the nodal officer and efforts be made to track those children.

Engineering Digital Repositories Landscape Analysis, and Implications for PerX
This paper draws on the experience of compiling a Listing of engineering repository sources and aims to help inform the development of a pilot subject based engineering repository cross search service.
The analysis reviews the landscape in the area of digital repositories within the subject area of engineering, as identified in the Listing. The document provides a synopsis of the current state of digital repository and metadata repository provision (including obvious gap areas) within engineering related disciplines. It proceeds to discuss various issues concerning repository provision and how they might relate to the provision of an Engineering Repository cross search service. The document concludes by considering the implications of the current engineering digital repository landscape for the PerX project.
For the most part, 'closed access' commercially produced repositories which do not currently allow free searching (such as various commercially available full-text and Abstract & Indexing services) are not included in the analysis or discussion. Many of these, such as ScienceDirect, Ei Compendex, Inspec, Technology Research Index, Web of Science, etc., are recognised as being extremely important, in terms of information provision, for the engineering community. However, the primary purpose of this list is to help inform the development of a Pilot Engineering Repository Xsearch service which does not require authentication (i.e. which cross-searches only freely available data or metadata).
Table 2 sums up the status of repository and metadata repository provision uncovered via the Listing of Engineering Repositories exercise;
|Brief Synopsis of Position|
Research Outputs 1: Preprints/Postprints
|Research Outputs 2: Technical Reports||Repositories
A number of UK repository related projects exist which aim to coordinate national access to resources (e.g. ePrints UK, Ethos, IRI Scotland). Additional nationally coordinated UK effort seems logical/possible in the following areas:
From the above synopsis it is obvious that a number of gap areas in the engineering repository landscape exist which include:
Subject Based Access,
Assessment Materials repositories.
These gap areas are discussed further in sections 3.3 to 3.7.
The picture concerning other repository types is fluid and in a state of fairly rapid development. Considerable advances are currently being made in the development and deployment of repositories for learning materials, e-thesis and at the institutional level. Often, coverage in these repositories is multidisciplinary in nature with no means for a subject based service to select subsets based on subject coverage. This presents a considerable challenge for subject based services which wish to cross search multiple resources, and is discussed in section 3.2.
Overall, the level of digital repository provision specifically for the engineering community appears to be relatively low. A considerable number of gap areas have been revealed and there is little in the way of repositories specifically aimed at the engineering community. A growing number of multidisciplinary repository sources will help in the future to improve access to certain content types, but with no specific emphasis on engineering materials. Some are interoperable and others are not.
At the same time, albeit with some notable gap areas, there are numerous metadata repositories of interest to engineering, some of which are already interoperable, others for which interoperable interfaces are in development, and yet more for which the situation is unknown.
This situation will have a bearing on the coverage provided by the Pilot Engineering Repository Xsearch. Inevitably, initial coverage will be very patchy.
A number of multidisciplinary repository sources have been identified with content which would be of interest to engineering (e.g. national repositories of research outputs, e-thesis, learning materials, technical reports and institutional/departmental materials). Clearly, subject based cross search services would wish to include relevant materials from such collections and OAI-PMH sets would seem to offer a mechanism to achieve this. In practice, however, the adoption of subject based sets within repositories is piecemeal in nature with some repositories offering clearly delineated subject groupings, others offering no subject breakdown whatever, and still others offering a more complex picture of many multiple sets (e.g. sets by publication status, sets by type of content (i.e. abstract/full text), sets by originating unit or author etc). The initial impression is that sets are often produced by data providers based upon their particular needs and internal organisational structures rather than the likely needs of service providers.
Examples of Repositories which provide Subject Based Sets
- NASA Technical Report Server (NTRS) -[ListSets]
- Digital Library Network for Engineering and Technology (DLNET) -[ListSets]
- Directory of Open Access Journals (DOAJ) -[ListSets]
- ArXiv.org -[ListSets]
Examples of Repositories which do not provide Subject Based Sets
- Networked Digital Library of Thesis and Dissertations Union Catalog (NDLTD) -[ListSets], Sets provided are based on institution of origin.
- National Engineering Education Delivery System (NEEDS) -[ListSets], No sets provided.
- Council for the Central Laboratory of the Research Councils (CCLRC) ePublication Archive -[ListSets], Sets provided are based on type of content, i.e. metadata or Full text.
- Australian Research Repositories Online to the World (ARROW) -[ListSets], No Sets provided.
Examples of Repositories which provide many multiple Sets
The current picture is therefore one in which the use of OAI-PMH sets to select particular subject groupings is limited to a small number of repositories which provide suitable sets. For others, suitable sets are simply not available or the situation is made prohibitively complex by large numbers of sets and the inability to easily gauge their relevance. In these situations the only current option is to harvest the entire multidisciplinary collection.
Some possible means to address this situation include;
A number of gap areas in repository provision have been identified including; Research data, Technical Reports, Journal Repositories, Subject Access and and Assessment.
Few repository sources were identified for engineering-specific research data. This situation can be contrasted to that of the Social Sciences and Humanities, for which the UK Data Archive provides access to over 5000 computer-readable datasets for research and teaching purposes.
Another gap area is that of UK technical reports. Technical reports from USA are covered well by repositories and metadata repositories, but UK technical reports have few equivalents apart from the CCLRC ePublication Archive. Technical reports are also not particularly well covered by commercially available 'closed access metadata repositories', such as the SIGLE database. The British National Bibliography for Report Literature which included this type of material ceased publication in 2003.
A further notable gap area within engineering is that of journal repositories. Although some initiatives such as Petroleum Journals Online and Hindawi are beginning to make progress, they are relatively small-scale and as yet unproven, and the situation can be contrasted with well established open access journal repositories in some other subject areas (e.g. BioMed Central, and PLOS), and subject areas for which public funding is currently encouraging development. Various journal metadata repositories exist, and there are also major commercially available 'closed access repositories' such as ScienceDirect, and 'closed access metadata repositories', such as CSA Technology Research Database and Ei Compendex. This situation will have a bearing on the content and potential effectiveness, from an information retrieval perspective, of a Pilot Engineering Repository Xsearch service. Coverage of certain resource types will be very patchy.
A major gap area identified is that of subject-based repository access for engineering. No sizeable subject-based repositories exist for engineering and no real community movement is evident which is likely to change this situation. Yet various subject based repositories have been developed which serve other disciplines. Several have existed for some time and have become well-established and heavily used, serving their respective communities. They include:
ArXiv.org (Physics, Mathematics, Non-linear Science, Computer Science, and Quantitative Biology).
Chemistry, Math and Computer Science Preprint Archives (Chemistry, Mathematics and Computer Science)
ClinMed NetPrints (Clinical Medicine and Health Research)
CogPrints (Cognitive Sciences: including Psychology, Neuroscience, Linguistics, and and many areas of Computer Science (artificial intelligence, robotics, vision, learning, speach, neural networks), Philosophy (e.g., mind, language, knowledge, science, logic), and Biology.)
Computing Research Repository (CoRR) (Computing)
Cryptology ePrint Archive (Cryptology)
E-BioSci (Life Sciences)
E-LIS (Library and Information Science)
EPRINT (Natural Science and Technology)
Project Euclid (Mathematics)
PubMed Central (Biomedical and Life Sciences)
Social Science Research Network (SSRN) (Social Science)
In addition to the above, the AMS Directory of Mathematics Preprint and e-Print Servers lists a number of subject repositories in mathematics, and 34 archives participate in the Open Language Archive Community (OLAC).
It is apparent therefore that subject repository services exist for some disciplines but not others,. It has been suggested that "Actually establishing and running a repository calls for a level of infrastructure, maintenance and administration which many subject communities cannot provide." (Hubbard 2005). With respect specifically to the engineering community, is the lack of subject based or journal repositories and the comparative lack of uptake of repositories simply a chicken and egg scenario? In other words, if a well-supported subject based repository were developed for engineering, or if a number of open access journals were initiated for engineering, would there be a resultant increase in uptake by the engineering community? The answer is probably no, or at least not to as great an extent as has happened in some other disciplines.
To explain much of the above, and to understand how repositories fit into the information landscape of engineering

Have you ever wondered about the witnesses on marriage certificates of ancestors? The ones that are obviously not brothers or sisters of the happy couple? Just after I'd given a lecture at WDYTYALive, a woman from the audience presented me with a wad of paperwork including a copy of one of her ancestors' wedding registrations. A witness at the marriage of boot finisher George Watson (aged 21), and Susannah Braham (aged 19) on the 22 September 1888 at St Jude's Bethnal Green, was Anthony Emm. His signature, round, cursive, confident, bold as brass stared out at us across the centuries.
The woman had taken the time to investigate Anthony Emm and amongst her papers were printouts of an Anthony Emm born 1873, the son of John Hen(e)ry Emm. Sadly, this Anthony would only have been 15 at the happy couple's wedding so I think it's more likely to have been his uncle Anthony Thomas William Emm born 1828 in Bethnal Green baptised 23 November 1828 at St Matthew's Church. This Anthony TW was a bootmaker and sexton in the 1851 census, recorded again as such in 1881. George Watson, living in Lark Row just five minutes' walk from Minerva Street (where Anthony lived all his life) must have known Anthony both professionally and from church.
Anthony TW Emm's family is a landmark amongst Emm family historians. His brother Walter Thomas was implicated in a celebrated murder in 1860 – Walter was acquitted. I have written extensively about this family so please contact me for further information.
Who Do You Think You Are/Live is the place to make new contacts, friends and discoveries about the world of genealogy. I had a wonderful day meeting up with the Guild of One Name Studies, Pen and Sword, the Society of Genealogists, Family Tree, and members of various family history societies. FHS are so helpful and informative, I wish I could join them all. As for their publications, check online for what's available; FHS have transcribed some fabulous and often obscure archives.
I specifically want to thank the descendant of Susannah Braham and George Watson for giving me a few happy hours delving into both our family histories. I should have asked for your name!
2 thoughts on "Astonishing encounter at WDYTYA?Live at NEC Birmingham 7 April 2017"
Hello, my name is John Emm I'm from Ocean City, MD and I had some questions referring to my ancestry. If you find the time to email I would appreciate it.
Hi John, I think I have already replied to you. Please go through my Guild of One Name Studies email if it is re family history. thanks. Adele


text: We studied the effects of 5-hydroxytryptamine (5-HT, serotonin) on the vertebrate neuronal somatic cell hybrid TCX11. We compared electrophysiological and pharmacological properties of the 5-HT response to those of the dopamine (DA) response. The cells developed delayed rectification and the ability to generate action potentials. Both 5-HT and DA caused graded depolarizations associated with increases in membrane conductance. The cells, however, were 10 to 100 times more sensitive to 5-HT than to DA. Responses to the amines desensitized during sequential or continuous application, and each neurotransmitter could desensitize the cell to a subsequent dose of the other neurotransmitter (cross-desensitization). Reversal potentials for both amines ranged from 0 to 15 mV from cell to cell, but on any given cell, the reversal potentials for 5-HT and DA were equal. We applied a variety of drugs, including classical DA and 5-HT antagonists, and found no drug that blocked the response to one amine without a similar inhibition of the response to the other amine. We conclude that, on the hybrid TCX11, there is a receptor that mediates a depolarizing response with a conductance increase after interaction with 5-HT and DA. Our data suggest that the receptor is best classified as a serotonin receptor.


can see that each step creates a value that is passed to the next expression as the final parameter. So all-keys is passed as the last parameter of the (map) expression, resulting in key-names, and then key-names is passed as the last parameter of the (sort) expression. In fact, ignoring the empty check for a moment, the sorted-names value is passed to the (s/join) expression as the last parameter as well.

This is a very important concept in Clojure; you may have heard people trying to express that you code in Clojure in terms of a "flow" of data through a series of expressions. We'll, you've just seen a very small example of this.

In fact, it is no simple coincidence that the last parameter is so important; this represents a careful and reasoned alignment of the parameters of many different functions in clojure.core and elsewhere, to ensure that flow can be passed as that final parameter, because it becomes central to the ability to combine functions and expressions together with minimal fuss.

We can use the <a href="_URL_ macro (pronounced "thread last") to rebuild our flow without having to come up with names for each step:

Molybdenum Disilicide Heating Rod
Molybdenum disilicide heating rod namely molybdenum disilicide heating element, is usually used in high-temperature oxidizing atmosphere and the maximum temperature can reach 1850 ℃. In 1947, a Swedish company produced the first molybdenum disilicide heating rod with continuous improvement, in the 1990s, the heating rod temperature increased to 1850 ℃ and named Kanthal Super 1900C heating element. China realized molybdenum disilicide heating elements industrial production in the 1980s. At present, the molybdenum disilicide heating element has became an important equipment used in heat treatment, casting, high-temperature sintering, and other industrial and laboratory.
High temperature heating rods (MoSi2 heating elements) is resistance heating element used in high temperatures field and it has many good properties. High temperature oxidation resistance, in high-temperature oxidizing atmosphere, its surface will generate dense quartz glass protective film to protect the heating rods matrix. Besides, this protective film has regenerative function and automatic removal surface impurities adhesion function. The resistivity of MoSi2 heating rod will rapidly increase with temperature rise, so that the heating rod at low temperatures has large power and the furnace can heat rapidly. At high temperature the power becomes small to prevent material overheating. In addition, the operation time has little effect on resistivity, that is, not aging, so old and new elements can be mixed used. Molybdenum disilicide heating rod is commonly used in electric furnace, because of its low power consumption, fast heating, easy to maintain and stable product performance.
MoSi2 heating rods not only can be used in an oxidizing atmosphere, but also can be used in N2, H2, NH2 and an inert gas, but the corresponding temperature is limited. MoSi2 is prone to accelerated oxidation at 400 ~ 700 ℃, so it is not suited to use in this temperature range. In addition, its surface load can reach tens of W / cm2, which is much higher than the metal heating element, so it is possible to make furnace wall to reach 100W/m2, greatly improve the production rate. MoSi2 heating rods can be made into U-shaped, W and L-shaped.
If you have got any interest in molybdenum metals, please feel free to contact us by email: _EMAIL_, _EMAIL_ or by telephone:86 _PHONE_/86 _PHONE_.

Unique pilot for future travel surveys
In the autumn of 2017, a unique pilot for future travel survey data collection methods is being conducted in Gothenburg. The pilot is running concurrently to a traditional travel survey. The aim of the pilot is to obtain a better understanding of how future travel surveys can be performed, by comparing different data collection methods that run in parallel.
Why travel surveys?
In order to plan for more sustainable transport systems, we need to understand how people use them. Today almost all decisions on transport investments and policy priorities are based on travel survey data, even though today's travel survey methods deliver data that is far from optimal.
Today most people use smartphones and have internet access 24 hours a day. This has the potential to give us much better information about how the transport system is used – which in the long run leads us to design a more efficient and human-centred system.
Demonstrating new innovative data collection methods
Traditional travel surveys ask respondents to complete details of their travel in paper-based questionnaires (and sometime by phone). The respondent should remember all trips made usually over a 24-hour period, how they travelled (bus, car, walk, etc) and the distance and time of each trip. This is a major weakness: the exact distances and times are hard for people to include in their responses, and shorter trips, as well as connecting trips (for example walking to a bus stop) are often forgotten. Completing such surveys can be a burden, and many who receive questionnaires do not complete them. Additionally, due to the high cost of performing these surveys, they are often only performed every 5 years or less frequently.
– "We are testing two new tools for data collection, an online questionnaire and a travel survey app called TRavelVU that helps to collect data", says Emeli Adell at Trivector.
The two new data collection methods will be compared with the traditional travel survey (paper-based) to improve our knowledge of data quality, comparability and representativeness.
Looking at different ways of recruiting respondents
– "But it's not just new tools we're testing," Emeli continues. We also want to understand how we can recruit respondents in a different way in the future. In the pilot, we are using three different recruitment methods for the online questionnaire and the travel survey app:
- random selection of postal addresses,
- web panel, and
– We will compare which groups are represented based on the different recruitment techniques as well as response types. We want to understand which sections of the population respond to different sections as a way to understand who is represented in the data, and how this should be considered when representing a representative picture of travel.
The pilot project is a joint effort between Transport Analysis, VTI (Swedish National Road and Transport Research Institute) and Trivector. The project is co-financed by the Swedish Transport Administration. It is a part of a larger project called "New solutions for future travel surveys" led by Transport Analysis.

I'm having problems with 'Learning Perl 6th Edition' Chapter 5 Question 1.
The question is to write a program that acts like cat but reverses the order of the output lines.
The book gives the answer as print reverse <>;
I'm running Perl v5.14.2
My code is:
#!/usr/bin/perl -w
print reverse <>;
After this I ran chmod 755 on the file to make sure it was executable.
On the command line I'm trying:
./tac.pl I am the walrus
I'm getting this in return:
Useless use of reverse in void context at ./tac.pl line 3.
Can't open I: No such file or directory at ./tac.pl line 3.
Can't open am: No such file or directory at ./tac.pl line 3.
Can't open the: No such file or directory at ./tac.pl line 3.
Can't open walrus: No such file or directory at ./tac.pl line 3.
Use of uninitialized value in reverse at ./tac.pl line 3.
Any idea what's causing this issue?
 - Hint: run cat I am the walrus – this doesn't work either. You should put multiple lines into a file of their own: cat text.txt and ./tac.pl text.txt. – amon Dec 28 '13 at 22:12
 - I believe the book has that on subsequent lines … i.e.. press RETURN after ./tac.pl – BRPocock Dec 28 '13 at 22:19
 - It works now when it uses a file as an argument. I was trying, as amon showed using cat as an example, to incorrectly pass command line arguments directly to the program when I needed to use a text file. – Kontophoros Dec 28 '13 at 22:33
 - Useless use of reverse in void context? You also have a problem with line endings, since perl didn't see the print. Use a CRLF for a Windows build of Perl, and LF endings elsewhere, including cygwin. – ikegami Dec 29 '13 at 5:18

The arguments on the command line are the names of the files that the line input operator reads. All of the the lines of all of the files are read, passed to reverse as a list, and that reversed list is passed to print.
Create these files:
fred
fred line one
fred line two
fred line three
barney
barney line 1
barney line 2
barney line 3
barney line 4
betty
betty line a
betty line b
betty line c
When you cat these, you get:
$ cat fred barney betty
fred line one
fred line two
fred line three
barney line 1
barney line 2
barney line 3
barney line 4
betty line a
betty line b
betty line c
Now, the Perl program we gave as the answer wants you to reverse that. betty line c should be first and fred line one should be last. When you run the program just as you have written it, that's what you should see:
$ perl tac.pl fred barney betty
betty line c
betty line b
betty line a
barney line 4
barney line 3
barney line 2
barney line 1
fred line three
fred line two
fred line one
In your question, you passed arguments to your program, but they didn't represent filenames. The line input operator, <>, had nothing to read because the magic that made that work fails when none of the files exist. That's where the weird warnings come in.
If you have further problems, adjust the question in the form I just showed you. Show the input files and exactly how ran your program. Good luck, :)

You are running the program in the wrong way when you are using the diamond operator. The program expects to find files named "I", "am", "the", and "walrus" when you run it in that way. Run it without parameters and you will have a program that reads from STDIN. I thought the book told you this before you got this far through it.

Strict scrutiny is a form of judicial review that courts use to determine the constitutionality of certain laws. To pass strict scrutiny, the legislature must have passed the law to further a "compelling governmental interest," and must have narrowly tailored the law to achieve that interest. A famous quip asserts that strict scrutiny is "strict in name, but fatal in practice."
For a court to apply strict scrutiny, the legislature must either have significantly abridged a fundamental right with the law's enactment or have passed a law that involves a suspect classification. Suspect classifications have come to include race, national origin, religion, alienage, and poverty.
Compare to intermediate scrutiny and rational basis.
Definition from Nolo's Plain-English Law Dictionary
A legal standard to determine the constitutionality of a statute, used when the statute implicates a fundamental right or relates to a suspect classification under the equal protection clause (such as race). To determine if a statute passes the test, a court considers whether the government has a compelling interest in creating the law, whether the statute is "narrowly tailored" to meet the government's objectives, and whether there are less restrictive means of accomplishing the same thing.

Help width widthSegments, heightSegments, and Height Map size on PlaneGeometry
Hi all,
I am in the process of building a Plane that has segments that I am changing their vertice height based on a height map.
Everything is technically working but my results do not represent exactly what I have in my change map.
NOTE: The height map image is a grayscale 100x100 PNG.
I would love if someone could help understand what line segments I should be using and based off that, what the size of my heightmap should be.
Here is the basic code below…
var planeSize = 100;
//init
function init() {
 generatePlane();
}
function generatePlane() {
 var container = $('#change-map');
 var scene = new THREE.Scene();
 var camera = new THREE.PerspectiveCamera( 50, container.width()/container.height(), 0.1, 8000 );
 camera.name = "Camera";
 var renderer = new THREE.WebGLRenderer();
 renderer.setSize( container.width(), container.height() );
 container.append( renderer.domElement );
 var img = new Image();
 img.onload = function () {

 textureLoaded();

 };
 img.src = "img/height-map-100.png";
 function textureLoaded() {
 var data = getHeightData(img, 1);

 var geometry = new THREE.PlaneGeometry( planeSize, planeSize, planeSize * .5, planeSize * .5 );
 var material = new THREE.MeshBasicMaterial( { wireframe: true } );
 var plane = new THREE.Mesh( geometry, material );
 for ( var i = 0; i<plane.geometry.vertices.length; i++ ) {
 plane.geometry.vertices[i].z = data[i] * .1;
 //; 3
 }
 plane.name = "Plane";
 scene.add( plane );

 }

 scene.add( camera );
 camera.position.z = planeSize * 1.5;
 var animate = function () {
 requestAnimationFrame( animate );
 renderer.render(scene, camera);
 };
 animate();
}
function getHeightData(img,scale) {

 if (scale == undefined) scale=1;

 var canvas = document.createElement( 'canvas' );
 canvas.width = img.width;
 canvas.height = img.height;
 var context = canvas.getContext( '2d' );

 var size = img.width * img.height;
 var data = new Float32Array( size );

 context.drawImage(img,0,0);

 for ( var i = 0; i < size; i ++ ) {
 data[i] = 0
 }

 var imgd = context.getImageData(0, 0, img.width, img.height);
 var pix = imgd.data;

 var j=0;
 for (var i = 0; i<pix.length; i +=4) {
 var all = pix[i]+pix[i+1]+pix[i+2];
 data[j++] = all/(12*scale);
 }

 return data;
}
Think I may of figured it out… The line segments needs to be planeSize - 1 and the height map needs to be the same size as the planeSize, so 100x100.
If anyone can verify or clarify or dispute this, please do so :slight_smile:

One question that comes up often with our homeowners is how to track how much energy is being produced. The solution to this is the monitoring systems. Currently Kiosk uses two different types of monitoring systems, depending on the type of system.
1. Microinverter systems have monitoring embedded into each microinverter, which are attached to each panel. They allow for per panel monitoring. You monitor the system by going onto the Enphase website and putting in your login and password. This is what the Enphase portal looks like:
2. Tigo boxes are designed for systems that use string inverters. The Tigos are attached to every panel, to monitor the production output and optimize production based on light conditions. You monitor the system by logging into the Tigo website and putting in your login and password. This is what the Tigo portal looks like:

It is important to remember that these calculations are for soluble oxygen content; the total oxygen content which includes both the soluble oxygen and
the oxygen associated with inclusions could be much higher.
For single element deoxidation, the solubility of oxygen in liquid iron at 1600°C (2912°F) is given as a function of the concentration of
the alloying element. In each case, the melt is in equilibrium with the respective pure oxide; e.g. SiO2, Al2O3 etc.
It can be clearly seen that aluminum is the strongest of the common deoxiders followed by titanium. Rare earths are about as strong aluminum as deoxidizers
and will be discussed later in detail.

A general framework for moment-based analysis of genetic data
In population genetics, the Dirichlet (also called the Balding--Nichols) model has for 20 years been considered the key model to approximate the distribution of allele fractions within populations in a multi-allelic setting. It has often been noted that the Dirichlet assumption is approximate because positive correlations among alleles cannot be accommodated under the Dirichlet model. However, the validity of the Dirichlet distribution has never been systematically investigated in a general framework. This paper attempts to address this problem by providing a general overview of how allele fraction data under the most common multi-allelic mutational structures should be modeled. The Dirichlet and alternative models are investigated by simulating allele fractions from a diffusion approximation of the multi-allelic Wright--Fisher process with mutation, and applying a moment-based analysis method. The study shows that the optimal modeling strategy for the distribution of allele fractions depends on the specific mutation process. The Dirichlet model is only an exceptionally good approximation for the pure drift, Jukes--Cantor and parent-independent mutation processes with small mutation rates. Alternative models are required and proposed for the other mutation processes, such as a Beta--Dirichlet model for the infinite alleles mutation process, and a Hierarchical Beta model for the Kimura, Hasegawa--Kishino--Yano and Tamura--Nei processes. Finally, a novel Hierarchical Beta approximation is developed, a Pyramidal Hierarchical Beta model, for the generalized time-reversible and single-step mutation processes.

This film looks at the reasons why, and follows the production process, from the carbon fibre sheet being cut with a pair of scissors in a sealed room, right through to Fernando Alonso driving out of the pit garage cocooned in a carbon fibre safety cell designed to withstand the force of a 200mph crash.

Optical Fibres Check us out at An optical fiber is made up of the core (carrying the light pulses), the cladding (reflecting the light pulses back into the core) and the buffer coating (protecting the core and cladding from moisture, damage, etc). Together, all of this creates a fiber optic which can carry up to 10 million messages at any time using light pulses. Fiber optics is the overlap of applied science and engineering concerned with the design and application of optical fibers. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communications. Fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles so they can be used to carry images, thus allowing viewing in tight spaces. Specially designed fibers are used for a variety of other applications, including sensors and fiber lasers. Light is kept in the core of the optical fiber by total internal reflection. This causes the fiber to act as a waveguide. Fibers which support many propagation paths or transverse modes are called multi-mode fibers (MMF), while those which can only support a single mode are called single-mode fibers (SMF). Multi-mode fibers generally have a larger core diameter, and are used for short-distance communication links and for...

Aero-TV: The Farnborough Kestrel - All Carbon-Fibre Business Aircraft Conceived as a new chapter in business aircraft, the Kestrel represents the application of advanced aerodynamics combined with state-of-the-art carbon-fibre composite construction. Developed by the British company, Farnborough Aircraft, the Kestrel made its first flight in July of 2006. Finally, at the Farnborough Air Show in 2008, the aircraft made its debut for European aviation enthusiasts. After Farnborough Aircraft came under new ownership at the beginning of 2009, the company has re-dedicated itself to seeking full certification of the Kestrel. Designed as a single engine turboprop business jet, the Kestrel merges speed, comfort, and operational flexibility unparalleled in the world of business and private jet aircraft. Due to its robust construction and heavy-duty undercarriage, the aircraft is capable of landing on the shortest of unprepared strips including sand, gravel, and grass. The 1000hp PT6 engine, however, allows the Kestrel to seamlessly integrate with the kind of jet traffic found at commercial airports. The aircraft sustains a climb rate at maximum weight of more than 3100 feet per minute and a maximum cruise speed above 350 knots. Able to travel distances up to 1500 nautical miles, the Kestrel is optimized to carry up to six passengers in luxury class comfort. Customers can choose from multiple cabin configurations including fitted private lavatory and pressurized luggage bay. The aircrafts luxury, however, does not translate to high operating costs...
