Landscape Epidemiology of Tularemia Outbreaks in Sweden
Figure 2. A) Spatial distribution of 56 places of tularemia transmission in Ljusdal, Sweden, 1995–2005, overlaid on a map with color-coded demographic data based on residential addresses. B) Disease cluster in an area of 25 km2 along the Ljusnan River in Ljusdal. Reported places of disease transmission and corresponding bacterial genotypes are shown. The 33 Francisella tularensis isolates belong to genetic group 1e and are of genotype ID 15 (red) or genotype ID 16 (black). Place of disease transmission was reported to be certain (circle), probable (square), or possible (diamond); patient residency was used when transmission data was unavailable (triangle).


ClayMetrics is new, but it is based on several well-established disciplines. Collection and analysis of clay shooting process and results can yield huge benefits by focusing practice time where it will be most useful. Deriving improved measures and analysis of performance are two more links in the success chain. That's the physical side.
It is generally recognized that top athletes perform at their peak when "in the Zone". First difficulty is recognizing when you are in the zone and when you are not. Second step is learning techniques to get in the Zone on demand and return to it as needed.
ClayMetrics is the scientific study of clay target shooting both physical and mental.

I don't want your money.
I'm looking to partner with others who take seriously the idea that science can assist them to prove the effectiveness of training, ideas, hardware, software and any other approach to improving your performance. I'm the statistician, I'm the researcher. Our research can be anonymous or not; your choice not mine. Let's talk.

IC RecorderICD-SX733/SX734/SX1000
Recording a few seconds in advance – the pre-recording function
The pre-recording function allows you to record sound sources for approximately 5 seconds prior to the point when you press souni_recREC/PAUSE. This is useful for recording during interviews or when making an open-air recording so that you will not miss an opportunity to start recording.
A: Sounds for 5 seconds are buffered in the memory.
B: Press souni_recREC/PAUSE to enter the recording standby mode.
C: Press souni_recREC/PAUSE.
D: Recording starts.
 1. In the stop mode, select MENU - the tab - "PRE REC," and then press .
 The menu items will be different depending on the model you are using.
 2. Press or to select "ON," and then press .
 PRE REC" is set to "OFF" when you purchase the IC recorder.
 3. Press souni_stopSTOP to exit the menu mode.
 4. Select a folder.
 5. Press and hold souni_recREC/PAUSE.
 The IC recorder enters the recording standby mode.
 Pre-recording starts and sounds for a maximum of the last 5 seconds are buffered in the memory. ( shows how long the sound is buffered in the memory.)
 6. To start recording, press souni_recREC/PAUSE.
 The standby for recording mode is released, and recording continues from the sound buffered in step 5.
 7. To stop recording, press souni_stopSTOP.
Note
 - If you start recording with pre-recording function using the built-in microphones, a click noise may be recorded when you press souni_recREC/PAUSE. To record with pre-recording function, we recommend using an external microphone.
 - When the remaining recordable time is less than 10 seconds, the pre-recording function is disabled. Before using the pre-recording function, erase unwanted files.
 - When 60 minutes have passed after the IC recorder entered the standby mode in step 5, the standby mode will be canceled and recording stops.
 - If you stop recording before step 6, sounds buffered in the memory will not be saved.
Hint
 - To cancel the pre-recording function, set "PRE REC" to "OFF" in step 2.

A STUDY ON DEVELOPMENT OF CRACKS ON PAINTINGS
OVER THE past 10 years there have been substantial developments in research on the mechanical behavior of paintings. The knowledge of processes leading to mechanical failure of paintings materials and their properties has been greatly enhanced through pioneering work by Mecklenburg (1982). It has been established that environmental changes induce dramatic responses in fabric and size. The layer of size is responsible for stress development during humidity decrease; high stiffness of fabric dominates in high humidity. The most brittle component of the composite—aged oil paint—fails when movements in the supporting size and fabric exceed its rupture strains.
Stress distribution on paintings and the resulting cracks in the paint layer were simulated on a computer with the Finite Element Method (FEM) (Kilpatrick 1980; Colville et al. 1982). Elastic properties of materials were assumed and based on uniaxial tests.
In this work the humidity-induced movements were observed on biaxially stretched samples of primed fabric with a commercially available brittle coating taking the place of aged paint. The coating is widely used in industrial stress analysis as a form of strain gauge; it cracks when strains in a support exceed its breaking strains. The results reveal nonelastic properties of size and are consistent with a study on dimensional response of size in changing humidities (Karpowicz 1989).

 1. Yes - default constructor, instance created on stack
 2. No
 3. Yes - default constructor, instance created on heap
share|improve this answer
 1. The statement would instatiate an object on the stack, call c'tor.
 2. Defines only a pointer variable on the stack, no constructor is called.
 3. The new operator would create an object in free store (usually the heap) and call c'tor.
But this code will not instantiate any object, as it does not compile. ;-) Try this one:
myClass class1;
myClass* class2;
myClass* class3 = new myClass;
 - class 1 is a local variable (on the stack), constructor called.
 - class 2 is a pointer, no constructor called.
 - class 3 is a pointer, the constructor is called, when new is executed.

@DarkDust: Ouch, right you are. – harper Feb 9 '11 at 6:50
In both #1 and #3 since you are actually making an instance of the object. In #2 you are merely declaring a pointer that doesn't point to an instance.

1 and 3, because in them you create a myClass object.

The constructor is called in cases 1 and 3 when a class is instantiated. The other one (2) only declares a pointer.

Creek Council Oak Tree, Prior to 1836
1750 South Cheyenne Ave.
The Creek Council Tree, a mature burr oak, marks the traditional "busk ground" chosen in 1836 by the Tulsa-Lochapoka clan of Creek Indians. They built a fire here and scattered the ashes brought from their last campfire in Alabama. In late 1834, they had begun their involuntary migration from Alabama under the control of the U.S. Government. It was a slow and painful trek; of the original group of 630, 161 died in route.
Their 1836 arrival was marked with a solemn and traditional ceremony. A "busk" site was chosen on a low hill overlooking the Arkansas River. Here, according to their traditions, they deposited ashes brought over the trail from their last fires in Alabama. The Tulsa-Lochapoka, a political division of the Creek Nation, established their "town." As late as 1896, the Lochapoka gathered here for ceremonies, feasts, and games.
The site was probably not used by the Indians after about 1900. Gradually it became a solid residential area for the growing city of Tulsa. The Creek Council Tree itself, however, survived. The oak, standing in its small, well-landscaped city park, serves as a meaningful memorial to the proud Indian tribe that brought law and order to a new homeland 173 years ago. I know of nothing in Tulsa history that is any older than this.
The Creek Council Tree was listed in the National Register on September 29, 1976. It was listed under National Register Criteria A, and its NRIS number is 76001576.
This historic old tree has its own little corner park.
Acorns from a Burr Oak tree. These are the largest acorns of any oak tree.

Public Comment Sought On Proposed New Facilities At Timpanogos Cave
Timpanogos Cave National Monument is considering building a new visitor center and making other improvements, and is also evaluating ways to deal with increased traffic on Hwy 92 in American Fork Canyon.
The Park Service provided the news release below.
Timpanogos Cave National Monument Seeks Public Comment on Environmental Assessment
The National Park Service (NPS) is soliciting public comment on the Environmental Assessment (EA) regarding the construction of a new visitor facility at the cave trailhead of Timpanogos Cave National Monument as well as the construction of an interagency center in conjunction with the Uinta-Wasatch-Cache National Forest Pleasant Grove Ranger District (PGRD) at the mouth of American Fork Canyon. The public, organizations, and other agencies are invited to review and comment on the EA.
The purpose of this project is to improve visitor and employee safety along state route 92 and from rockfall and flood hazards. Provide for visitor enjoyment and education; and provide new efficient facilities for the Monument and PGRD.
The EA evaluates five alternatives and the potential impacts of each: 1) Alternative A, the No Action Alternative; 2) Alternative B, to implement a mandatory shuttle system between the interagency visitor center the visitor contact station at the Monument cave trailhead; 3) Alternative C, to implement a shuttle system on weekends and holidays between the interagency visitor and the visitor contact station as well as reconfigure visitor parking at the cave trailhead; 4) Alternative D (the Preferred Alternative), to realign State highway 92 and reconfigure the cave trailhead site for safety; and 5) Alternative E, reconfigure parking at the cave trailhead and provide concession operations at Swinging Bridge Picnic Area. Elements common to all action alternatives include the construction of a visitor contact station without concession operations at the cave trailhead, construction of the interagency visitor center in Highland City, safety improvements, reassigning facilities for administrative and staff operations, and enhancing a cave tour ticket reservation system.
The EA has been prepared in accordance with the National Environmental Policy Act of 1969 (NEPA), the Council on Environmental Quality (CEQ) regulations (40 CFR 1500 et seq), and NPS Director's Order 12: Conservation Planning, Environmental Impact Analysis, and Decision-making (DO-12).
The 30-day review and comment period starts June 15, and continues through July 15, 2012. To see the EA, _URL_ or visit the Monument administrative office, Visitor Center, or the offices of the US Forest Service Pleasant Grove or Provo during the comment period. An open-house will be held at the Monument Visitor Center on July 2, 2012 from 5:30 pm until 8:00 pm to answer questions regarding the EA.
Written comments may be submitted on the PEPC website or may be sent to:

If you have just had a new baby, you must register the birth. This applies to all children born in the Netherlands. You must register the birth within 3 days in the municipality where they were born. The mother, father or the mother's female partner (duomoeder) can register the birth.
You must register the birth of a new baby within 3 days, not counting the day of the birth. For example, was your child born on a Monday? Then you must register the birth on Thursday at the latest.
If the third day falls on a Saturday, Sunday or public holiday, the deadline for registering the birth is extended until the next working day. If that means you have only 1 day to register the birth, you will be given an extra day, to ensure that there are always at least 2 days to register the birth.
Late birth registrations
If you are late registering the birth, then the Registrar of Births, Deaths, Marriages and Civil Partnerships (ambtenaar van de burgerlijke stand) will inform the public prosecutor (officier van justitie). You may then have to pay a fine.
A baby's birth can be registered by the mother, father or the mother's female partner.
If the mother, father or mother's female partner are not able to register the birth, then the birth can be registered by:
someone who was present at the birth;
the owner of the house in which the child was born;
an employee of the institution where the child was born, such as a hospital.
If none of these people are able to register the birth, the birth can be registered by or on behalf of the mayor of the municipality where the child was born, or where the child was found if they are a foundling.
You do not have to bring the baby with you when you register the birth.
If your baby was born in a vehicle, for example in a car, ambulance, train or aeroplane, you must register the birth at the place of arrival, i.e. the location where your baby leaves the vehicle. This applies if that location is in the Netherlands.
If your baby is born during an international flight or an international sea voyage and the location where you arrive is not in the Netherlands, there are 2 options:
- if the boat or aircraft is registered in the Netherlands, you must obtain a temporary birth certificate (geboorteakte) from the captain of the aircraft or boat.
- If the boat or aircraft is not registered in the Netherlands, you must obtain a birth certificate from the authorities in the local area.
When you arrive at your destination, you must obtain a temporary birth certificate at your place of arrival and send this as quickly as possible to the civil registrar in the municipality of Den Haag (The Hague).
Bring these documents with you when registering a birth at the municipality:
- A valid form of identification.
- An acknowledgement of parenthood (akte van erkenning) or declaration of surname choice (akte van erkenning of naamskeuze) if issued before the birth.
- A declaration of birth, issued by the hospital or midwife.
The civil registrar at the municipality will issue the birth certificate. This is written proof that you have registered the birth of your child.
The birth certificate contains the following information:
- the baby's details, for example: name, date of birth, place of birth and time of birth;
- the personal details of the parent(s).
The birth certificate is the official proof of birth, and also proves who the child's parents are.
This is how it works in your (future) place of residence
Municipality of Noardeast-Fryslân: Registering a birth
Inform the municipality directly of the birth of your child. You can do so:
- At the service desk
You can book an appointment for this, for more information contact us at _EMAIL_
You pay a fee for a birth certificate. For more information, contact the municipality at _EMAIL_

Evaluation of Wear in an Automotive Transmission using PM Gears
In 2008, Höganäs together with KBE+ redesigned the transmission for the smart fortwo car. The ambition was to create a PM friendly, reduced weight transmission that could be built into the original transmission housing whilst maintaining reliability. The reverse engineering analysis showed that this could be done without sacrificing service life, and with an accumulated weight reduction on the gears of 1 kg. In 2010, this transmission was built into a smart fortwo, driven to the PM World Congress in Florence and exhibited there. Since the congress, the smart car has been used as an everyday driver for eight years and accumulated 200 000 km.
In this paper, an evaluation of the PM gears will be presented. The gears are visually inspected after 200 000 km of real driving. The wear, as well as any other damage to gears and synchronizers will be investigated and discussed. Topography measurements before and after 200 000 km will be shown for quantification of wear, and pictures of the gear flanks will be shown to establish the general condition of the gears. From the design work the stress conditions are known, and from the logging system in the car, information on cycles and load can be estimated to further understand the load history of the gears.

Tim Gallant was the first author to write a book-length defense of paedo-communion in over a century (at least that we're aware of). Then, he self-published his book (Feed My Lambs) under the publishing name of Pactum Reformanda (Latin: "covenant or pact," & "reforming.") Tim now hopes to produce a line of works which are both scholarly and accessible to the layman. As the definitions above suggest, he is interested in promoting a rigorously biblical covenant theology.

solve linear programms
Syntax
GLPK.MIPSolve(Objective_f:POLYNOM, EQ_Poly:LIST, LE_Poly:LIST, GE_Poly:LIST, Bounds:LIST, IntNum:LIST, Binaries:LIST, MinMax:STRING)
Description
Please note: The function(s) explained on this page is/are using the ApCoCoAServer. You will have to start the ApCoCoAServer in order to use
it/them.
 - @param Objective_f: A linear polynomial which is equivalent to the linear objective function.
 - @param EQ_Poly: List of linear polynomials, which are equivalent to the equality-part in the list of conditions.
 - @param LE_Poly: List of linear polynomials, which are equivalent to the lower or equal-part in the list of conditions.
 - @param GE_Poly: List of linear polynomials, which are equivalent to the greater or equal-part in the list of conditions.
 - @param Bounds: List of lists with two elements. Each List contains the lower and upper bounds for each variable. You can choose between INT or RAT for the type of each bound, if you type in a (empty) string, then it means minus infinity (first place) or plus infinity (second place).
 - @param IntNum: List of variables, which should be integer. Note: For each variable in this list, the borders get rounded (lower bound: up and upper bound: down). In the case that the lower rounded bound becomes greater then the upper rounded bound, glpk returns: Solution Status: INTEGER UNDEFINED - Value of objective function: 0.
 - @param Binaries: List of variables, which should be binaries (0 or 1).
 - @param MinMax: Minimization ("Min") or maximization ("Max"), that's the question.
 - @return List of linear polynomials, the zeros of the polynomials are the points where the optimal value of the objective function is archieved
First we want to discuss a rather easy example.
Example
We want to maximize the Function y = - 1/2x,
with the two conditions y ≤ 6 - 3/4x and y ≥ 1 - x and the bounds 0 ≤ x ≤ 6 and 1/3 ≤ y ≤ 4.
We prename the input of GLPK.MIPSolve-function.
Use S::=Q[x,y];
OF := 1/2x + y;
LE := [3/4x + y - 6];
GE := [x + y - 1];
Bounds:=[[0,6], [1/3,4]];
IntNum:=[x,y];
Then we compute the solution with
$GLPK.MIPSolve(OF, [], LE, GE, Bounds, IntNum, [], "Max");
And we achieve:
Solution Status: INTEGER OPTIMAL
Value of objective function: 5
[x[1] - 2, x[2] - 4]

Indicator glass remodelling
- Checking the sample provided by the client, looking for defects, damages, and deformations that need to be corrected when creating the new CAD model. When re-modelling old, used parts, a comprehensive examination of the samples to list the defects that have developed over time and use is crucial.
- Since the geometry of the glass features no fixed measuring points, the exact dimensions can only be obtained by scanning. Preparing the sample for scanning.
- The shiny surfaces are treated with a matte, so-called scanner spray, which coats the sample surfaces with a white powder 1-2 microns thick, eliminating glaring and providing for successful scanning.
- The scanning creates so-called point clouds, which are used to create the mesh.
- Preparation of a CAD model taking into account the specifications of the selected production process. In this case, the remanufacturing will be done using a 3D resin printing process.
- Comparison of the finished CAD model with the scanned mesh.

qc is a testing tool that lets you write properties that you expect to hold true, and let the computer generate randomized test cases to check that these properties actually hold. For example, if you have written compress and decompress functions for some data compression program, an obvious property to test is that compressing and decompressing a string gives back the original string. Here's how you could express that:
"""Test that compressing and decompressing returns the original data."""
data = qc.str() # An arbitrary string. Values are randomized.
self.assertEqual(data, decompress(compress(data)), repr(data))
That's an ordinary test with Python's built-in unittest framework (which is why there's so much boilerplate). Alternately, you could do the exact same thing with a different testing framework, like the minimally verbose, quite pleasant nose. The _USER_.property decorator runs the decorated function several times, and each time the values returned by functions like qc.string() are different. In other words, QuickCheck is compatible with pretty much every unit test framework out there; it's not particularly demanding.
Functions like qc.str(), qc.int(), and so on, generate arbitrary values of a certain type. In the example above, we're asserting that the property holds true for all strings. When you run the tests, QuickCheck will generate randomized strings for testing.
You'll notice that I said "randomized", not "random". This is intentional. The distribution of values is tweaked to include interesting values, like empty strings, or strings with NUL characters in the middle, or strings containing English text. In general, QuickCheck tries to give a good mix of clever tricky values and randomness. This is essentially what you would do, if you had to write really thorough test cases by hand, except that you don't have to do it. In practice, the computer has fewer preconceptions about what constitutes sane data, so it will often find bugs that would never have occurred to you to write test cases for. It doesn't know how to subconsciously avoid the bugs.
You're not limited to the built-in arbitrary value functions. You can use them as building blocks to generate your own. For example:
def __init__(self, x, y):
self.x, self.y = float(x), float(y)
"""Get an arbitrary point."""
x = qc.int(-20, 20)
y = qc.int(-34, 50)
return Point(x, y)
You can then use this to generate arbitrary point values in properties. Here's a nose-style test:
pt = point()
assert abs(pt.x) + abs(pt.y) >= math.sqrt(pt.x**2 + pt.y**2), (pt.x, pt.y)
When you run this, something magical happens: QuickCheck will try to generate tricky values for both the x and y variables in the Point class, together, so you'll see points like (0, 0), (1, 1), (0, 1), (385904, 0), as well as totally random ones like (584, -35809648). In other words, rather than just drawing x and y values from a stream of random numbers with some tricky values in it, QuickCheck will actually try to generate tricky combinations of x and y coordinates.
Functions for getting arbitrary data
- int(low, high) gives ints, between the optional bounds low and high.
- long(low, high) gives longs, between the optional bounds low and high.
- float(low, high) gives floats, between the optional bounds low and high. No Infinities or NaN values.
str(length=None, maxlen=None) gives strings, of type str. The encoding is UTF-8. If length is given, the strings will be exactly that long. If maxlen is given, the string length will be at most maxlen characters.
- unicode(length=None, maxlen=None) gives unicode strings, of type unicode. If length is given, the strings will be exactly that long. If maxlen is given, the string length will be at most maxlen characters.
- name() gives names, in Unicode. These range from the prosaic, like "John Smith", to the exotic -- names containing non-breaking spaces, or email addresses, or Unicode characters outside the Basic Multilingual Plane. This is, if anything, less perverse than the names you will see in a sufficiently large set of Internet data.
- nameUtf8() is the same as name().encode('utf8').
- fromList(items) returns random items from a list. This is mostly useful for creating your own arbitrary data generator functions.
- randstr(length=None, maxlen=sys.maxint) gives strings of random bytes. If length is given, the strings will be exactly that long. If maxlen is given, the string length will be at most maxlen bytes.
The strings produced by str and unicode are randomized, but some effort has been put into making them sufficiently perverse as to reveal bugs in a whole lot of string processing code. The name list is loosely based on horrible memories of seeing name processing code crash on real-world data, over and over and over again, as it became ever more clear that the world is mad, and we are truly doomed. (This feeling passes once you get enough test coverage and things finally stop crashing. There is hope!)
The name and string example data in qc.arbitrary may be interesting as a source of more deteministic test case data. Feel free to borrow any of it. The internals are magic, but of the magical internal parts, the most interesting ones are in qc.arbitrary and qc.


The Radio PSA: 4 Things You Need to Know to Use the Medium
While most communicators are familiar with broadcast and print public service announcements, radio is a different animal, says Bill Goodwill, CEO of Goodwill Communications. Here are four tips on how to leverage the airwaves for the most effective PSAs:
 1. Ensure Good Production Values: Since radio is not a visual medium, your radio production must create a "theater of the mind" via words and sound effects.
 2. Offer a Variety of Formats and Lengths: Produce PSAs in several different formats, including one for middle-of-the-road (MOR), which can be used by any station. Also, offer various spot lengths—30 and 60 seconds—and send them in MP3 format on a CD.
 3. Seek Endorsements: Get endorsements from organizations such as the National Association of Broadcasters and get your PSAs posted on their Spot Center.
 4. Involve State Broadcast Associations: Every state has a state broadcast association and you should send them your PSAs so they will forward them to their member stations. Click here for a list.
PR News subscribers can read about how Wreaths Across America incorporated radio PSAs into their PR efforts in the case study: "Extensive Media Relations Effort Makes Wreath Campaign at Arlington National Cemetery a Success."


= (x + 1) - (y + 1)) while multiplication is symmetric under skewing (x*y = 2x * y/2).

In formal specification, we can express symmetries as properties of the system. Most commonly this is transpositional symmetry. If F(x, y) is some predicate (boolean function), then F is symmetric if

all x, y | F(x, y) => F(y, x)

Where => is implication. Transpositional symmetry is so common that if you tell someone your business logic has a symmetry property that's usually what they'll think you mean.

Symmetry properties are useful in formal specification because they're common, easy to think of, and often influence the design. If you ever have a relation between two things of the same type, you can ask yourself if there's a symmetry relation you need to check for.

A more interesting example

Facebook has three kinds of graph relations between users. You can be Friends with a user, you can Invite a user, and you can Follow a user. We can define the predicate Friends(u, v) to mean "u and v are friends".

Friends is symmetric: if I'm friends with you, you're friends with me. More formally:

FriendshipSymmetric = all u, v: User | Friends(u, v) => Friends(v, u)

This is one reason why we don't store many-to-many relationships as an array field in a user's SQL record. It's too easy then for the system to break symmetry, like if u.friends = {a, b, c, v} while v.friends = {d, e}. Having a separate relationship table makes it easier to keep things in order.

Follow is asymmetric. Follow(u, v) tells us nothing about Follow(v, u).

Invites are interesting. If I invite you, you shouldn't be able to invite me. If you try to invite me, it should accept the invitation, making us both friends. Invites are antisymmetric: Invited(u, v) => !Invited(v, u). Antisymmetry properties are really easy to break. What if the invite service is eventually consistent and we invite each other simultaneously? You also have to worry about feature interaction. Say there's a way to merge two accounts: A invites B, B invites C, and then A and C merge. What happens then?

(Presumably in both cases we'd drop both invites and add a friendship relationship, but that'd have to be explicitly coded and it's something that'd be easy to miss.)

Symmetry optimizations

Symmetry is also important in optimization problems, like constraint solving. Consider the problem of conference scheduling: we've surveyed the attendees on their most-anticipated talks, and are now trying to assign talks to slots (rooms + times) to minimize the number of "favorites conflicts". If two rooms are indistinguishable, it doesn't matter whether we assign talk A to slot R1T1 and B to R2T1 or if we assign B to R2T1 and A to R1T1. Therefore we don't need to check any layouts involving the latter. Typically you'd optimize this by adding a "symmetry breaking" constraint, like "talk A must be in R1".

I use this a lot in model checking TLA+, too, which has a built-in symmetry-breaking feature. I don't know how common it is in other FM tooling. This paper seems to suggest it's applicable to SMT solving, at least.

Besides that I've done very little writing the last couple weeks. I'm just in a slump: I sit down to write and the words all come out wrong. It happens sometimes and there's nothing to do about it but wait it out.

So instead of working I've been learning Raku.1 It originally got on my radar after I ranted about dynamic languages and a couple of users told me I'd like Raku. I finally checked it out last week to see if it'd make a good "calculator language". I use a hodgepodge of Python, J, Frink, and Excel to do math and they all have their own big drawbacks, so it'd be nice if Raku could round them out.

After several days of experiments, I'm at a loss of how to describe Raku. The best I can come up with is that the language was designed by a bunch of really intelligent gremlins. Gremlins who spent a lot of time gathering feedback from other gremlins.

Weird Operators

Raku has no qualms about using Unicode operators. You check set membership with ∈. There's also ∉, ∋, and ∌. It's also fine with alphanumeric infix operators. String repetition op is x. Function composition is o.

text: Improper manual material handling (MMH) techniques are shown to lead to low back pain, the most common work-related musculoskeletal disorder. Due to the complex nature and variability of MMH and obtrusiveness and subjectiveness of existing hazard analysis methods, providing systematic, continuous, and automated risk assessment is challenging. We present a machine learning algorithm to detect and classify MMH tasks using minimally-intrusive instrumented insoles and chest-mounted accelerometers. Six participants performed standing, walking, lifting/lowering, carrying, side-to-side load transferring (i.e., 5.7 kg and 12.5 kg), and pushing/pulling. Lifting and carrying loads as well as hazardous behaviors (i.e., stooping, overextending and jerky lifting) were detected with 85.3%/81.5% average accuracies with/without chest accelerometer. The proposed system allows for continuous exposure assessment during MMH and provides objective data for use with analytical risk assessment models that can be used to increase workplace safety through exposure estimation.

New in IDL 8.6: IDLTasks
Anonym
ENVITasks have been around for a few years now, but they didn't help those of you who only have IDL and not ENVI as well. In IDL 8.6 we are happy to announce that the ENVITask concept has been carried over to work in pure IDL without ENVI. Many of the features are the same, but there are slight differences that I want to point out in this post.
The first and most obvious is how you construct an IDLTask. Rather than launch ENVI and then call the ENVITask()function, you can call the IDLTask()function at any point in time. As the help points out, you can pass in either a scalar string that is the name of the task you want or its filename, or you can pass in a Hash object that is the task definition (what you would get if you called JSON_Parse() on a task file). If you pass in a string that isn't a filename (relative or absolute), then it is treated as a task name. The function will then look at !PATH and search for all .task files in each folder listed there. It catalogs all the .task files it finds, but if there are multiple folders with the same base name only the first is recognized(just like how IDL handles multiple .pro or .sav files with the same base name found in !PATH). The list of .task files is filtered to those with the correct IDLTask schema, which currently is only "idltask_1.0". This way we don't accidentally pick up an ENVITask files and cause confusion. If a.task file with the same base name as the requested task name is found, it is used as the task definition. If no exact match is found, but partial matches exist, then helpful error messages are returned telling you about the name(s) that partially match, so you can correct your code. I should point out that the current working directory (which can be retrieved by calling CD with the CURRENT keyword) is searched before any of the folders in !PATH, so that can affect the behavior of IDLTask().
The "idltask_1.0" task schema used for IDLTasks in IDL 8.6 is very similar to the "envitask_3.0" schema used by ENVITasks in ENVI 5.4. The notable exception is that the TYPE property of your parameters won't understand ENVI class types like ENVIRaster. But all the basic datatypes available in IDL are supported by IDLTasks – strings, Booleans, and numbers, as well as List, Hash, OrderedHash, and Dictionary.
Another difference is how you interact with IDLTasks on GSF as opposed to ENVITasks. The service endpoint for IDLTasks will be http://hostname:port/ese/services/IDL,while the ENVITasks use http://hostname:port/ese/services/ENVI. The different endpoints are used to discriminate between the requests that should use the IDLTask() function vs the ENVITask() function to load the requested task.
Easy GSF deployment is one of the primary reasons you would want to build IDLTasks in the first place. If you have IDL functions or procedures that you are used to calling directly, then you are probably wondering why you would want to wrap them in an IDLTask. As a C++ developer in a previous life, I appreciated the type safety that C++ requires, so I also appreciate the parameter validation that IDLTasks provide. When developing your custom IDLTask, you will have to spend some time thinking about what the inputs and outputs are for your code, but once you do that you won't need to worry about writing lots of input validation code, the IDLTask framework will take care of that for you. The IDLTasks are also self-documenting like ENVITasks, so if someone else hands you a .task file and .sav file, you can load the task and then learn all about the parameter names, their types, cardinalities, and hopefully even descriptions. All of this information makes it possible to deploy your algorithms on GSF for running in the cloud, with all the same introspection capabilities over the REST endpoint. Alternatively, you can set up batch processing using some sort of folder watch capability to spawn IDLTaskEngine instances to automatically run your code on each file that appears on your system.

§ Lord Braine of Wheatley
asked Her Majesty's Government:
How many abortions have been performed within the North Thames Region, under the provisions of the Abortion Act 1967 (as amended); and how many and what percentage of such abortions were performed in an emergency to save the life of the mother.
§ Lord Mackay of Ardbrecknish
The total number of abortions carried out under the Abortion Act, to women usually resident in the North Thames health Region1, from 1970 to 19942 was 752,736. During this period, 19 abortions, 0.003 per cent. of the total number of 196WA abortions performed, were carried out in an emergency, certified by the operating practitioner as immediately necessary, to save the life of the woman3.
1Figures are based, where possible, on 1994 health authority boundaries. Other boundary changes have not been reflected in the figures.
2 Figures for 1968–69 are not held on a comparable basis.

No one can deny the importance of an academic institution, as it plays an important role in enhancing the learning capabilities and skills of students. Besides providing knowledge, the core objective of an academic institute is to groom social interaction skills of younger generation while helping them to succeed in the competitive world. Choosing an educational institution can be a daunting task for parents, since it is one of the most important decisions parents can make in their children's education. Therefore, mostly educational instates used academic logos to clearly show the mission statement, sincerity and dedication level of the institute to the parents and students. If truth be told, an academic logo design is the most convincing and effective way to draw attention of intended audience. The features given below are some important characteristics of academic logos:
Imagery related to an Academic Logo
Since an academic logo design is a clear representation of an institute, therefore it is very important to choose more relevant images for such logos. Images such as libraries, books, torches, sword, pencils or other related symbols are used in an academic logo design, making this visual appearance impressive and clear. This will clearly explain the educational and enlightening nature of the particular institute.
Typefaces linked to Academic Logos
When it comes to an academic logo, sensible font selection is the most important factor to create an understandable graphical image for the viewers. Explicable and professional fonts can make the logo design easily readable, helping people to read and remember the name of your institute. This will surely provide recognition and a strong credibility to your educational establishment.
Colors Selection for an Academic Logo Design
To represent the mission statement and actual purpose of academic institutes, an appropriate color selection is an absolute must for academic logos. Dark colors such as navy blue, black, brown or green are some of the best color choices for an academic logo design. The right colors can definitely make a positive impression in the minds of students and parents, making it very easy for the people to choose your institute among others.
These are a few prominent characteristics of an academic logo design which can serve as a unique brand identity for your organization. The main objective for creating academic logos is to make people aware of your educational services and convince them to choose your academic institute instead of others.

The Dinner Party Project is a dynamic family-focused food education program involving children (5th-8th graders) in the entire process of producing a dinner party for their families at a school or community center.
Through a fiveto eight-week project, fifth though eighth grade students are taught about nutrition, food safety, meal planning, table setting, etiquette, and cooking. This powerful experience of planning a dinner party also deepens their understanding of the value of community, family, teamwork, and sharing, while building self-esteem and having fun.
The curriculum handbook provides a "Dinner Party Planner" with all the information s/he needs to conduct the program, coordinate with school staff, enlist parental and culinary help, and create local press. Homework assignments are structured to involve parents and families.
The Dinner Party Project began in Spring 2001 in the New York City metro area, and has spread across the nation to 27 U.S. cities serving 6,470 students. There have been more than 50 Dinner Parties conducted in elementary schools, middle schools, a charter school, a community girls club, The Harlem Boys and Girls Choir Academy, and a county extension center.

Objective(s): To: 1) examine the fluoride concentrations in commercial child formula dentifrices (CFD)s; and 2) investigate the effect of arginine incorporation in CFDs on fluoride bioavailability.
Study Design: Five commercial CFDs were examined for fluoride concentrations. Total, total soluble, and insoluble fluorides in CFDs were determined by the modified Taves acid-diffusion method (TAD). Ionic F and MFP were estimated by modified direct method with standard addition technique. L-arginine (L-Arg)/L-arginine monohydrochloride (L-Arg.HCl) were incorporated at 2% w/w in the commercial CFDs. The pH of the toothpaste slurries, buffer capacity of the added Arg, potentially available fluorides (PAF) and 1-min PAF by TAD were determined. Results: The CFDs had 4 to 32% of insoluble fluorides. Addition of L-Arg/L-Arg.HCl significantly improved the fluoride bioavailability in CFDs (p<0.05). Incorporation of L-Arg significantly increased the pH of toothpaste slurries (p<0.05); while L-Arg.HCl decreased the pH. Principal component analysis showed that L-Arg.HCl decreased the pH of toothpaste slurries due to the presence of Cl in the form of HCl; whereas the inherent elements/molecules (Na/P/Pi/F) remain distinct with unidentified influence on the variables. Conclusion(s): The CFDs containing NaF only have higher concentrations of bioavailable fluoride. Incorporating arginine (L-arginine or L-arginine monohydrochloride) at 2% w/w improves fluoride bioavailability of the child formula dentifrices.

Hrithik Roshan to share his fight against stuttering
314 0
While he recently voiced his support towards Deepika Padukone who courageously came out in the open to discuss about depression, Hrithik Roshan continues to spread awareness and talk about his fights and struggles to inspire his other fans. It is a renowned fact that Hrithik Roshan as a child faced several issues due to his stuttering. However, instead of bowing down to the constant stigma, he decided to fight.
In a recent interview, the actor expressed his concern to several people who continue to face social stigma when it comes to speech-related impediments and mentioned that he is contemplating with the idea of writing a book. His intention is to inspire people and boost them with self-confidence with his story that revolves around his way of overcoming struggles and stigmas.
Reminiscing about his battle with stammering, Hrithik described it as lonely and also revealed about how kids often were mean to him due to his stuttering. He further also stated that children often don't have as much information or knowledge to understand these kind of issues. Yet at the same time, he looks back at these incidents as something that gave him immense strength and belief in him.
Hrithik Roshan also went out to spread this message to his fans wherein he requested them to accept their shortcomings and use them as a stepping stone to grow.


Including line numbers in typeset output
For general numbering of lines, there are two packages for use with LaTeX, lineno (which permits labels attached to individual lines of typeset output) and numline. (Numline is considered obsolete, but remains available from the archive.)
Both of these packages play fast and loose with the LaTeX output routine, which can cause problems: the user should beware…
If the requirement is for numbering verbatim text, moreverb, or fancyvrb (see including files verbatim) may be used. Class memoir also provides the necessary facilities.
One common use of line numbers is in critical editions of texts, and for this the edmac package offers comprehensive support; ledmac is a LaTeX port of edmac.
The vruler package sidesteps many of the problems associated with line-numbering, by offering (as its name suggests) a rule that numbers positions on the page. The effect is good, applied to even-looking text, but is poor in texts that involve breaks such as interpolated mathematics or figures. Documentation of the package, in the package itself, is pretty tough going, though there is an example (also inside the package file).

Modelling Behavioural Requirements and Alignment with Verification in the Embedded Industry
Paper i proceeding, 2017
Formalising requirements has the potential to solve problems arising from deficiencies in natural language descriptions. While behavioural requirements are rarely described formally in industry, increasing complexity and new safety standards have renewed the interest in formal specifications. The goal of this paper is to explore how behavioural requirements for embedded systems can be formalised and aligned with verification tasks. Over the course of a 2.5-year project with industry, we modelled existing requirements from a safety-critical automotive software function in several iterations. Taking practical limitations and stakeholder preferences into account, we explored the use of models on different abstraction levels. The final model was used to generate test cases and was evaluated in three interviews with relevant industry practitioners. We conclude that models on a high level of abstraction are most suitable for industrial requirements engineering, especially when they need to be interpreted by other stakeholders.

text: In the present study, the effectiveness of ohmic thawing (OT) on temperature distribution (TD) was evaluated by using a non-destructive measurement method: thermal imaging (TI). The effects of both OT process parameters and sample properties on TD of thawed minced beef were determined. Thermal images were taken from the central cross-sectional area of a thawed sample. In the first part of the study, the effects of OT system parameters (voltage gradient; 10-13-16 V/cm and electrode type; E1:titanium foil electrode with a smooth surface, E2: needled-type titanium electrode, E3: titanium electrode with pyramid surface shaped) and sample shape (X: 13 x 4 x 3 cm(3); Y: 13 x 6 x 2 cm(3); Z: 13 cm height x 3.91 cm diameter) were analyzed in detail. The best thawing condition (electrode type E2 and sample shape Y) was determined by taking into account of thawing time and TD properties obtained from a developed TI processing technique. In the second part of the study, the effects of OT process on TD properties of minced beef having different fat contents (2-10-18%) were compared with those of two different conventional thawing processes (stationary cold ambient + 4 degrees C -RT and under cold running water + 4 degrees C -WT). The percentage of thawed portions in central section was above 68% for OT and varied between 12 and 54% for CT. Rectangular-shaped samples had more homogeneous temperature distributions than cylindrical samples (p < 0.05). TI could be used to control the process by non-destructive monitoring of temperature during OT.

01 Nov Possible horizontal Ecodesign measure for internal combustion engines
EGMF Position paper on possible horizontal Ecodesign measure for internal combustion engines
EGMF together with the engine manufacturers industry (Euromot), the construction machinery industry (CECE), the agricultural machinery industry (CEMA) and the material handling industry (FEM) opposed a potential future horizontal energy efficiency requirement on internal combustion engines. Indeed, such a measure is unfeasible considering the variety of types and power ranges of combustion engines installed in non-road mobile machinery. In addition, the pressure imposed by other upcoming regulatory requirements on engines renders such a measure inappropriate. Finally, the importance of energy efficiency in manufacturers' R&D makes such a measure unnecessary.

How To Hard Reset iPhone 7 or iPhone 7 Plus (Guide)
iPhone 7 and iPhone 7 Plus have a different kind of home button. Even though the home button looks the same, it is actually not a mechanical button like the one found on previous models. Instead of having an actual click, it gives an illusion of a click when users presses the button with a vibration effect. Thanks to iPhone 7's Taptic engine the vibration 'almost' feels like a normal click. Because iPhone 7 does not have a traditional button Apple has changed the way we can hard reset iPhone 7 or iPhone 7 Plus. The new way is as simple as it was before and involves user pressing two buttons at the same time. In this post we will show you how you can hard reset an iPhone 7 or iPhone 7 Plus in case your device gets stuck etc.
Tutorial For iPhone 7 or iPhone 7 Plus Hard Reset
In order to hard reset your iPhone 7 or iPhone 7 Plus follow the simple steps below.
Step 1: Hold your iPhone 7 in such a way that you can press the power and volume down buttons at the same time.
Step 2: Once you are comfortable press and hold the Power button and the Volume down buttons at the same time.
Step 3: Keep the buttons pressed as the screen turns off.
Step 4: Let go of the buttons as soon as you see the Apple logo.
The turning off of the screen and appearance of the Apple logo means you have successfully hard resetted your iPhone 7 or iPhone 7 Plus. This new way of iPhone hard reset might take a while to get used, however this change is for the better. Since both the buttons you are supposed to press are on either sides of the device, this makes it easier for users to press them together with one hand only.
Let us know what you think of this new hard reset method in the comments section below.

Sample Selector is a tool for creating and editing
samples, or groups of data you compare across—they're
not "samples" in the statistical sense, but more like filters.
By default, a single sample exists: "All Data". With the Sample
Selector, you can create new samples to organize your data.
You can use samples to:
Compare across conditions
Narrow the scope of data analysis to a specific time range,
set of students, problem category, or unit of a curriculum (for example)
A sample is composed of one or more filters, specific
conditions that narrow down your sample.
Creating a sample
The general process for creating a sample is to:
Add a filter from the categories at the left to the composition
area at the right
Modify the filter to select the subset of data you're interested
in, saving it when done
View the sample preview table to see the effect of adding your filter,
making sure you don't have an empty set (ie, a filter or combination
of filters that exclude all transactions).
Name and describe the sample
Decide whether to share the sample with others who can view the
Save the sample
The effect of multiple filters
DataShop interprets each filter after the first as an additional
restriction on the data that is included in the sample. This is also known
as a logical "AND". You can see the results of multiple filters in the
sample preview as soon as all filters are "saved".
A project is primarily a group of related datasets. Each project has a principal
investigator (PI) and potentially a data provider, as well as one or more project
admins. If you are a project admin for this project, you can edit its metadata. The
difference between PI and project admin is described here.
Access to datasets is granted by project. To gain access to a private project, click
the Request Access button and provide a brief reason why you would like
access. The status of your request will be shown on the Access Requests page.

Why does fire fighting pipe crack when grooving?
Grooved pipe connection is often used in the construction and installation of fire fighting pipes. Therefore, it is often necessary to groove fire fighting pipe. If the pipe cracks during grooving, it will be very annoying. Why does fire fighting pipe crack when grooving? The reasons mainly involve pipe material factors and human factors.

I. Material factors

Pipe material is the primary factor. If pipe cracks during grooving, firstly check pipes' quality issue. Common quality issues that cause pipe cracking mainly include:

(1) The problems of welded pipe itself: the shrinkage stress of welded pipe is too high, uneven heated or unreasonable welding method and sequence will lead to weld cracking

(2) Insufficient pipe thickness: pipes' wall thickness is required when grooving, in general ,only the thickness meets the national standard, pipes can be grooved according to construction requirements. However, in order to save costs, some contractors use thin pipes instead of thick ones, which will cause some problems during grooving.

(3)Pipe is not straight: Pipes may collide during handling and long-distance transportation, resulting in pipe bending. When grooving bending pipe , cracks may occur on one side due to non-homogenous force stresses.

(4) Poor quality of pipes: Good raw materials are needed to produce high-quality galvanized pipes. However, in order to save costs, some manufacturers use wasted materials to make pipes, which will lead to relatively poor quality of pipes, low carbon content and easy to crack when making grooves.

UE 4.25.3 + FMOD 2.01.04
Distance set in event in FMOD Studio is about 30 times larger then in game.
For example in FMOD Studio setting attenuation distance to 12.7 makes it work in game on distance close to 387. Like on attached image:
What can we do to use same values in both?
Have a great day
Are you able to describe the setup you used to measure and report the distance on the UE4 side?
Are you using FMOD::System::set3DSettings to change the distance scale in FMOD?
I suspect this is probably a confusion about the units used for measuring distances.
FMOD Studio uses a system where 1 unit is 1 meter, UE4 uses uu ("Unreal Units") where 1 uu is 1 centimeter. Our integration converts UE4 position vectors from centimeters to meters by dividing the position vector's components by 100.
So if the distance between the listener and an FMOD event is calculated in UE4 then we expect the value to be 100 times larger than the numeric value of an automatic distance parameter on the FMOD event.
The distance measured in UE4 being 30 times the FMOD distance could be explained if there is a scale factor on the value being displayed in UE4 or if the distance scale in FMOD has been changed.
Glad to see this is solved now, I wonder if you could explain any further? No pressure but if you can then it might prove very useful for future users with similar issues who happen on this topic
We were measuring distance not from listener but from object to which listener is attached. That was causing odd value.

Terrestria is the plane on which the planet Earth is located.
EDIT: Due to limited Magic information, the best assumption is that planes are individual planets. No other information can be garnered from the true Magic: the Gathering storyline. The best explanation for our universe being in the MtG multiverse is billions of overlays on a gigantic plane, causing each individual cosmic body that exists in real life.
EDIT: The formation of a seperate article, i.e. 'The AoM Multiverse' is suggested.
It is commonly accepted that a plane is not a planet, though in most cases the focus of a plane will take place on a particular planet within this plane. The confusion arises in that most planes are confused with planets, due to the fact that most planes are named after their primary planets.(). Each plane is a seperate 'universe' however, the word itself has the stigmatic effect of only meaning there can be one'verse'. Each'verse' is a plane, within a wider multiverse. This given it means that any number, and any variant of a plane is possible within the multiverse, it can be said that the Magic multiverse contains an infinite number of planes. (). As part of the possibility, and as is used in these storylines, Terrestria is part of this multiverse.

Keywords: Epilepsy, metabolic changes, Ramadan
Abstract
Introduction: Fasting during the month of Ramadan can leads to changes in the electrolyte and hematocrit balance. We compared the metabolic situations of epilepsy patients who presented to the emergency department following a seizure, either when fasting during the month of Ramadan or during normal periods.
Method: The study included 20 consecutive patients experiencing an epileptic seizure while fasting during the month of Ramadan in 2010, and other 20 patients who experienced a seizure while not fasting.All patients presented to the emergency service of Ankara Training and Research Hospital.Venous blood gas, full blood count, kidney function tests, sodium, potassium, chlorine, blood glucose and full urine analysis were required for the patients. The patients were followed for approximately 12 hours.
Findings: No statistically significant differences were observed between the fasting group and control group in terms of average age of the patients and gender distributions.No significant differences were observed in terms of blood pH, anion gap, osmolarity,or base deficit (p>0.05). Ketone level was significantly higher in the urine of the fasting group (p<0.047).
Conclusion:
There was no significant difference found in metabolic changes between fasting epilepsy patients and the control group. The only significant difference was the higher levels of ketone in fasting epilepsy patients compared ton on-fasting group.

I'm trying to use Kryo to read/write objects to disk: _URL_
Couple questions:
 - How do I determine the size of my byte buffer? If I make it too small it crashes, too large it eats up lots of memory and the files are huge. Follow up, shouldn't kyro already know how big the object is since it's the one serializing it?
 - What is a good way to convert them from a ByteBuffer to byte array and back?
 - Anyone have a effective and quick way of reading/writing objects to file using Kyro? My yucky xml is about 100 times faster (which includes parsing, not just i/o) which doesn't make sense according to the benchmarks. I tried using ByteBuffer writing to FileChannel.

You actually don't need to muck with ByteBuffer at all, you can use the com.esotericsoftware.kryo.ObjectBuffer
Pretend you have a class MyObject that you want to serialize;
MyObject o = new MyObject();
Kryo kryo = new Kryo();
ObjectBuffer ob = new ObjectBuffer(kryo);
byte[] myByteArray = ob.writeObject(o);
share|improve this answer
Do you mean that after obtaining byte array I can dump it to file? – Bostone Feb 21 '12 at 1:30
And if so what is a simplest way to deserialize back to object? – Bostone Feb 21 '12 at 1:41

For you to understand why do dogs bury bones, it's necessary to have a glimpse on the way in which wolves hunt in the wild.
Small preys including mice are chased, stalked, and pounced upon by single wolves working for themselves. These pounces trap the prey under the front feet. Then, it seized and bitten quickly after which it's gobbled down.
Bigger preys like rabbits are treated in the same manner. If preys of this size are hard, these might be shaken vigorously, yet typically some bites are all that's needed to subdue this. Medium-sized preys like small deer and sheep are killed through throat bites.
The burying process consists of digging holes with the front feet while clasping the meat in jaws. When the cavity is huge enough, the wolf opens its jaws and allows the meat drop into it. Then, they use their snout to push the soil back on top.
Once the hole is already covered, they make some pressing down movement with their snout and wander off. They will return the following day, digging up the meat with their front feet, then grab that using their jaws to eat.
Why Do Dogs Bury Bones?
When it comes to dogs, it's now clear to assume what conditions should be present to encourage them to bury food. First and foremost, there should be food surplus. Hungry dogs eat everything they could. Only if there's something left over that couldn't be eaten would be carried into the backyard and buried.
Commercial dog foods even in homes where dogs are overfed by their owners are impossible to hold and carry in the jaws while digging a hole. That is why dogs that are fed only with soft food in dog bowls won't have the chance to bury anything. However, if they're provided with big bones they do have something they could hide in the hole.
The main reason why bones are famous as the burying object is that though the dogs in question aren't overfed and don't have any food surplus, a big bone that's impossible to break up and eat, has about the essential quality of the food object that can't be eaten easily. It has a leftover quality that persuades even hungry dogs to bury bones.
Several pet dogs that are overfed with soft foods may be seen performing a strange remnant of burying foods. They know a dish of surplus food is great food, yet they're not hungry, so they attempt to just bury the whole food in a room.
See dog bury bones in action:
Stop Your Dog From Burying Bones
If you don't like your dog to bury bones in your backyard, there are some options you can consider to stop them. One of these is training him properly and disciplining him that it's not good to bury bones. If you do not have more time to train your dog, you can always hire someone to do it for you.

- Compatible devices connect with the Garmin Connect Mobile app to automatically sync your data and connect with others
Train Hard, Run Free
The Running Dynamics Pod easily clips onto your waistband to measure the running dynamics you need to beat yesterday. It gives you the option to run without a heart rate monitor chest strap. Once paired with your compatible smartwatch, just clip it to the back and center of your waistband and start your run.
Review Your Form
View and analyze important running metrics such as your cadence, stride length, ground contact time and balance, vertical oscillation and vertical ratio. These biomechanical measurements can help you understand your running form so you can perform better on race day.
How It Works:
The Running Dynamics Pod has an accelerometer in the module that measures torso movement to calculate these 6 running metrics:
- Cadence is the number of steps per minute. It displays the total steps (right and left combined).
- Ground contact time balance displays the left/right balance of your ground contact time while running. It displays a percentage. For example, 53.2 with an arrow pointing left or right.
- Stride length is the length of your stride from 1 footfall to the next. It is measured in meters.
- Vertical oscillation is your bounce while running. It displays the vertical motion of your torso, measured in centimeters for each step.
- Vertical ratio is the ratio of vertical oscillation to stride length. It displays a percentage. A lower number typically indicates better running form.
- Ground contact time is the amount of time in each step that you spend on the ground while running. It is measured in milliseconds.

Download Ivana K's solution
The Solution
Writing a top-tier macro that meets the contest requirements involves three challenges, in my opinion.
The first challenge is simply determining how to obtain the children of a part component. Its not as simple as you might think. IComponent2::GetChildren only returns child components, not child features, which means that on a part component this method returns an empty array. To get the children, we actually need to get the IFeature pointer than corresponds to the part component and then use IFeature::GetChildren. This method returns whatever is listed in the Parent/Child dialog box of a part component. The lesson is, a component is considered a feature by the SolidWorks API. With that in mind, we know to traverse the assembly as a set of features rather than components.
The second challenge is understanding how to write recursive functions. Recursion refers to a function referencing itself. A great example of recursion can be seen in the API Help example Traverse Assembly at Component and Feature Levels Using Recursion. Indeed, many contestants used a heavily-trimmed version of this macro as a means of traversing the FeatureManager tree. Recursion lets a programmer re-use code, which can result in having to write fewer lines of code overall. Such was the case with this macro.
The third challenge is knowing tricks and shortcuts within the VBA or VB.NET programming language to remove as many lines as possible. Ivana's winning solution illustrates this well:
 1. The text displayed in ISldWorks::SendMsgToUser2 is actually the return value of the getNames functions.
 2. Most of the variable names are declared as function arguments or as For Each loop elements, instead of on their own line. (Note that declaring variables in For Each loops is only possible in VB.NET.)
 3. Automatic type-casting is used to reduce the number of variable declarations. For example, using "swMod.FeatureByName(c.Name2).getchildren" to get the child features of a component.
 4. Use AndAlso and OrElse operators (available in VB.NET) to effectively squish two conditional statements into one line. Normal And and Or operators require all statements to be verified, whereas AndAlso and OrElse will begin executing the statements contained within the conditional once the outcome is guaranteed. So in Ivana's case, the following logic was applied to each component in the assembly: If the component is a sub-assembly then traverse its features, or, if the component has child features then it must be a part component so add the names of those child features to the final results string.
We can see, then, that VB.NET does offer some significant advantages in terms of reducing line length.
(Note: Should you desire to count the lines in the winning solution on your own, keep in mind that comments, blank lines, Imports statements, and Class declarations are not counted. Also, lines containing 2 or more variables declarations on the same line are counted as separate lines.)
