sequence is a high performance sequential log analyzer and parser. It sequentially goes through a log message, parses out the meaningful parts, without the use regular expressions. It can achieve high performance parsing of 100,000 - 200,000 messages per second (MPS) without the need to separate parsing rules by log source type.
sequence is currently under active development and should be considered unstable until further notice.
If you have a set of logs you would like me to test out, please feel free to open an issue and we can arrange a way for me to download and test your logs.
Log messages are notoriusly difficult to parse because they all have different formats. Industries (see Splunk, ArcSight, Tibco LogLogic, Sumo Logic, Logentries, Loggly, LogRhythm, etc etc etc) have been built to solve the problems of parsing, analyzing and understanding log messages.
Let's say you have a bunch of log files you like to parse. The first problem you will typically run into is you have no way of telling how many DIFFERENT types of messages there are, so you have no idea how much work there will be to develop rules to parse all the messages. Not only that, you have hundreds of thousands, if not millions of messages, in front of you, and you have no idea what messages are worth parsing, and what's not.
The typical workflow is develop a set of regular expressions and keeps testing against the logs until some magical moment where all the logs you want parsed are parsed. Ask anyone who does this for a living and they will tell you this process is long, frustrating and error-prone.
Sequence is developed to make analyzing and parsing log messages a lot easier and faster.
The industry has came up with a couple of different approaches to solving the log parsing problem. In a way, you can say the log parsing problem has been solved, because analysts have a lot of different tools to choose from when they need to understand logs.
Commercially, there are companies such as Splunk, ArcSight, Tibco LogLogic, SumoLogic, LogEntries, Loggly, LogRhythm, etc etc etc that can provide you either an on-premise or in-the-cloud (SaaS) solution. They provide different capabilities and feature sets depending on the primary use case you are targetting.
Open source wise, you have tools such as ElasticSearch, Greylog2, OSSIM, and a few others that wants to provide you end-to-end capabilities similar to the commercial offerings. There are also libraries such as liblognorm and logstash you can use to build your own tools.
And then there's Fedora's Project Lumberjack, which "is an open-source project to update and enhance the event log architecture" and "aims to improve the creation and standardize the content of event logs by implementing the concepts and specifications proposed by the Common Event Expression (CEE)."
Unfortunately all of these tools have one or more of the following problems.
First, it looks like many of these open source efforts have all been abandoned or put in hibernation, and haven't been updated since 2012 or 2013. liblognrom did put out a couple of updates in the past couple of years.
It is understandable. Log parsing is BORING. I mean, who wants to sit there and stare at logs all day and try to come up with regular expressions or other types of parsing rules? LogLogic used to have a team of LogLabs analysts that did that, and I have to say I truly appreciated their effort and patience, because I cannot do that.
Second, many of these commercial and open source tools uses regular expression to parse log messages. This approach is widely adopted because regular expression (regex) is a known quantity. Many administrators already know regex to some extend, and tools are widely available to interpret regex. In the early days of log analysis, Perl was used most often, so most rules you see are written in PCRE, or Perl Compatible Regular Expression. However, the process of writing regex rules is long, frustrating, and error-prone.
Even after you have developed a set of regular expressions that match the original set of messages, if new messages come in, you will have to determine which of the new messages need to be parsed. And if you develop a new set of regular expressions to parse those new messages, you still have no idea if the regular expressions will conflict with the ones you wrote before. If you write your regex parsers too liberally, it can easily parse the wrong messages.
Third, even after the regex rules are written, the performance is far from acceptable. This is mainly due to the fact that there's no way to match multiple regular expressions at the same time. The engine would have to go through each individual rule separately. It can typically parse several thousands messages per second. Given enough CPU resources on a large enough machine, regex parsers can probably parse tens of thousands of messages per second. Even to achieve this type of performance, you will likely need to limit the number of regular expressions the parser has. The more regex rules, the slower the parser will go.
To work around this performance issue, companies have tried to separate the regex rules for different log message types into different parsers. For example, they will have a parser for Cisco ASA logs, a parser for sshd logs, a parser for Apache logs, etc etc. And then they will require the analysts to tell them which parser to use (usually by indicating the log source type of the originating IP address or host.)
Last but not least, none of the existing tools can help analysts determine what patterns to write in order to parse their log files. Large companies can sometimes generate hundreds of gigabytes, if not terabytes, of data and billions of log messages per day. Sometimes it will take a team of analysts hundreds of hours to comb through log files, develop regex rules, test for conflicts and then repeat this whole process.comments powered by Disqus


Flow (mathematics)
For flows in graph theory, see flow network.
Flow in phase space specified by the differential equation of a pendulum. On the x axis, the pendulum position, and on the y one its speed.
In mathematics, a flow formalizes the idea of the motion of particles in a fluid. Flows are ubiquitous in science, including engineering and physics. The notion of flow is basic to the study of ordinary differential equations. Informally, a flow may be viewed as a continuous motion of points over time. More formally, a flow is a group action of the real numbers on a set.
The idea of a vector flow, that is, the flow determined by a vector field, occurs in the areas of differential topology, Riemannian geometry and Lie groups. Specific examples of vector flows include the geodesic flow, the Hamiltonian flow, the Ricci flow, the mean curvature flow, and the Anosov flow. Flows may also be defined for systems of random variables and stochastic processes, and occur in the study of ergodic dynamical systems. The most celebrated of these is perhaps the Bernoulli flow.
Formal definition
A flow on a set X is a group action of the additive group of real numbers on X. More explicitly, a flow is a mapping
such that, for all xX and all real numbers s and t,
It is customary to write φt(x) instead of φ(x, t), so that the equations above can be expressed as φ0 = Id (identity function) and φsφt = φs+t (group law). Then, for all t , the mapping φt: X X is a bijection with inverse φ−t: X X. This follows from the above definition, and the real parameter t may be taken as a generalized functional power, as in function iteration.
Flows are usually required to be compatible with structures furnished on the set X. In particular, if X is equipped with a topology, then φ is usually required to be continuous. If X is equipped with a differentiable structure, then φ is usually required to be differentiable. In these cases the flow forms a one parameter subgroup of homeomorphisms and diffeomorphisms, respectively.
In certain situations one might also consider local flows, which are defined only in some subset
called the flow domain of φ. This is often the case with the flows of vector fields.
Alternative notations
It is very common in many fields, including engineering, physics and the study of differential equations, to use a notation that makes the flow implicit. Thus, x(t) is written for φt(x0), and one might say that the "variable x depends on the time t and the initial condition x = x0". Examples are given below.
In the case of a flow of a vector field V on a smooth manifold X, the flow is often denoted in such a way that its generator is made explicit. For example,
Orbits
Given x in X, the set φ(x,t): t ∈ ℝ is called the orbit of x under φ. Informally, it may be regarded as the trajectory of a particle that was initially positioned at x. If the flow is generated by a vector field, then its orbits are the images of its integral curves.
Examples
Autonomous systems of ordinary differential equations
Let F: RnRn be a (time-independent) vector field and x: RRn the solution of the initial value problem
Then φ(x0,t) = x(t) is the flow of the vector field F. It is a well-defined local flow provided that the vector field F: Rn Rn is Lipschitz-continuous. Then φ: Rn×R Rn is also Lipschitz-continuous wherever defined. In general it may be hard to show that the flow φ is globally defined, but one simple criterion is that the vector field F is compactly supported.
Time-dependent ordinary differential equations
In the case of time-dependent vector fields F: Rn×RRn, one denotes φt,t0(x0) = x(t), where x: RRn is the solution of
Then φt,t0(x0,t,t0) is the time-dependent flow of F. It is not a "flow" by the definition above, but it can easily be seen as one by rearranging its arguments. Namely, the mapping
indeed satisfies the group law for the last variable:
One can see time-dependent flows of vector fields as special cases of time-independent ones by the following trick. Define
Then y(t) is the solution of the "time-independent" initial value problem
if and only if x(t) is the solution of the original time-dependent initial value problem. Furthermore, then the mapping φ is exactly the flow of the "time-independent" vector field G.
Flows of vector fields on manifolds
The flows of time-independent and time-dependent vector fields are defined on smooth manifolds exactly as they are defined on the Euclidean space n and their local behavior is the same. However, the global topological structure of a smooth manifold is strongly manifest in what kind of global vector fields it can support, and flows of vector fields on smooth manifolds are indeed an important tool in differential topology. The bulk of studies in dynamical systems are conducted on smooth manifolds, which are thought of as "parameter spaces" in applications.
Solutions of heat equation
Let Ω be a subdomain (bounded or not) of ℝn (with n an integer). Denote by Γ its boundary (assumed smooth). Consider the following Heat Equation on Ω × (0,T), for T > 0,
with the following initial boundary condition u(0) = u0 in Ω .
The equation u = 0 on Γ × (0,T) corresponds to the Homogeneous Dirichlet boundary condition. The mathematical setting for this problem can be the semigroup approach. To use this tool, we introduce the unbounded operator ΔD defined on by its domain
(see the classical Sobolev spaces with and
is the closure of the infinitely differentiable functions with compact support in Ω for the norm).
For any , we have
With this operator, the heat equation becomes and u(0) = u0. Thus, the flow corresponding to this equation is (see notations above)
where exp(D) is the (analytic) semigroup generated by ΔD.
Solutions of wave equation
Again, let Ω be a subdomain (bounded or not) of ℝn (with n an integer). We denote by Γ its boundary (assumed smooth). Consider the following Wave Equation on (for T > 0),
with the following initial condition u(0) = u1,0 in and .
Using the same semigroup approach as in the case of the Heat Equation above. We write the wave equation as a first order in time partial differential equation by introducing the following unbounded operator,
with domain on (the operator is defined in the previous example).
We introduce the column vectors
(where and ) and
.
With these notions, the Wave Equation becomes and .
Thus, the flow corresponding to this equation is where is the (unitary) semigroup generated by .
Bernoulli flow
Ergodic dynamical systems, that is, systems exhibiting randomness, exhibit flows as well. The most celebrated of these is perhaps the Bernoulli flow. The Ornstein isomorphism theorem states that, for any given entropy H, there exists a flow φ(x,t), called the Bernoulli flow, such that the flow at time t=1, i.e. φ(x,1), is a Bernoulli shift.
Furthermore, this flow is unique, up to a constant rescaling of time. That is, if ψ(x,t), is another flow with the same entropy, then ψ(x,t) = φ(x,t), for some constant c. The notion of uniqueness and isomorphism here is that of the isomorphism of dynamical systems. Many dynamical systems, including Sinai's billiards and Anosov flows are isomorphic to Bernoulli shifts.

lavResiduals: Residuals
Description Usage Arguments Value References Examples
View source: R/lav_residuals.R
Description
'lavResiduals' provides model residuals and standardized residuals from a fitted lavaan object, as well as various summaries of these residuals.
The 'residuals()' (and 'resid()') methods are just shortcuts to this function with a limited set of arguments.
Usage

3
lavResiduals(object, type = "cor.bentler", se = FALSE, zstat = TRUE,
 summary = TRUE, h1.acov = "unstructured", add.type = TRUE,
 add.labels = TRUE, add.class = TRUE, drop.list.single.group = TRUE)
Arguments
object
An object of class lavaan.
type
Character. If type = "raw", this function returns the raw (= unscaled) difference between the observed and the expected (model-implied) summary statistics, as well as the standardized version of these residualds. If type = "cor", or type = "cor.bollen", the observed and model implied covariance matrices are first transformed to a correlation matrix (using cov2cor()), before the residuals are computed. If type = "cor.bentler", both the observed and model implied covariance matrices are rescaled by dividing the elements by the square roots of the corresponding variances of the observed covariance matrix.
se
Logical. If TRUE, show the estimated standard errors for the residuals.
zstat
Logical. If TRUE, show the standardized residuals, which are the raw residuals divided by the corresponding (estimated) standard errors.
summary
Logical. If TRUE, show various summaries of the (possibly scaled) residuals. When type = "raw", we compute the RMR. When type = "cor.bentler", we compute the SRMR. When type = "cor.bollen", we compute the CRMR. An unbiased version of these summaries is also computed, as well as a standard error, a z-statistic and a p-value for the test of exact fit based on these summaries.
h1.acov
Character. If "unstructured", the observed summary statistics are used as consistent estimates of the corresponding (unrestricted) population statistics. If "structured", the model-implied summary statistics are used as consistent estimates of the corresponding (unrestricted) population statistics. This affects the way the asymptotic variance matrix of the summary statistics is computed.
add.type
Logical. If TRUE, show the type of residuals in the output.
add.labels
If TRUE, variable names are added to the vectors and/or matrices.
add.class
If TRUE, vectors are given the 'lavaan.vector' class; matrices are given the 'lavaan.matrix' class, and symmetric matrices are given the 'lavaan.matrix.symmetric' class. This only affects the way they are printed on the screen.
drop.list.single.group
If FALSE, the results are returned as a list, where each element corresponds to a group (even if there is only a single group). If TRUE, the list will be unlisted if there is only a single group.
Value
If drop.list.single.group = TRUE, a list of (residualized) summary statistics, including type, standardized residuals, and summaries. If drop.list.single.group = FALSE, the list of summary statistics is nested within a list for each group.

1. Introduction
 DIA-DB is a web-based open tool for performing chemoinformatics to a chemical and protein database related to diabetes mellitus. This tool serves to three main objectives:
 - Task automation for virtual screening of a diabetes database.
 - Ease the use of "in silico" tools to users not familiar with these techniques.
 - Reduce time and money expenses related to "in vitro" experimentation.
 DIA-DB technically allows three types of database searching:
 - Query in DIA-DB to get information about the approved or experimental drugs containd in the chemical database.
 - Inverse virtual screening, by performing large-scale inverse docking in a set of proteins involved in diabetes, aiming to identify potential target of a query compound.
 - 3D shape similarity of antidiabetic bioactive compounds accesible in the DIA-DB chemical database.
 2. DIA-DB tool services
 a. Consulting DIA-DB drug database
 Performing a search in the database is an easy task the user can do from the search window in the site. The user can perform the search to get information about the approved or experimental drugs containd in the chemical database by two means:
 - Compound name: click on Name for performing a query by the common or the chemical systematic name of a compound.
 - Smiles code: click on Smiles and start inserting the smiles code of the query compound.
 screenshot of the search site
 A list with the matching compounds will be displayed:
 screenshot of the search by name
 If the user wants to get all the drugs in the database it can be done by filling the blank space with % either from the Name or the Smiles option.
 For checking the information contained in the database for any compound the user should click on the drug name. Then a new page will be loaded displaying data about the molecule.
 screenshot of metformin information
 b. Performing inverse virtual screening
 Performing a search in the database is an easy task the user can do from the search window in the site. The user can perform the search to get information about the approved or experimental drugs containd in the chemical database by two means:
 This action can be done from the Submit calculations site and checking Docking option. Then insert the smiles code of the query molecule in the LIGAND(SMILES) blank field. If the user does not know the smiles code, it can be obtained by drawing the molecule with the JME applet that will be displayed after clicking on Draw Molecule botton. Once the molecule has been drawn just click Submit Molecule and the smiles code for the user compound will be inserted in the LIGAND(SMILES) field. DIA-DB server will automatically generate the 3D coordinates information by means of Open Babel (www.http://openbabel.org).
screenshot of JME applet
 Now insert a valid email address and click SUBMIT DATA. Once the calculations are finished the user will be noticed by email with a link to the results.
 c. 3D shape similarity
 Go to the Submit calculations site and check Similarity option. Now follow the same steps as for performing inverse virtual screening.
 The "in silico" methods implemented are DIA-DB is suitable only for small molecules like drugs. Please avoid to upload as the query macromolecules like proteins, nucleic acids, poly-peptides or other bio-inorganic compounds containing atoms other than C, H, O, N, P, S, and halogens. Jobs involving those molecules will have no results.
 3. Results visualization and download
 After simulations are completed, DIA-DB server will send an email to the user with a link that will open a site where the results will be displayed, this can take from several hours to two or three days depending on the query compound and cluster occupation. Inverse docking results will be displayed, in a table, in descending order by the value of the binding affinity from the docking simulation.
 screenshot of JME applet
 The columns in the table show from left to right:
 - 2D diagram showing the interactions that take place between the protein and the molecule in the conformation with the best binding affinity predicted in the docking simulation. This image is built with PoseView (_URL_).
 - 3D image of the query molecule (in blue) overlaped to the compound that was co-crystalized with the protein target in the PDB model (in green). The code on top of the image corresponds to the PDB (_URL_) code of the protein target.
 - Binding affinity value in Kcal/mol obtained after the simulation for the query compound and protein target complex. The bindig affynity is broken down into its energy components and they are displayed in a graphical representation.
 Each raw in the table corresponds to the result of the simulation of the docking between the molecule introduced by the user and every protein target in the database.
 3D shape similarity results are also displayed in a table. In the left side of the table it is specified the PDB code of the cristal containing the ligand that is similar to the user input molecule followed by the PDB code for that ligand. On the right side it appears the score value [range 0-1] for the similarity of both ligands. The image displayed shows the overlapping of the molecule used as input by the user (in blue) and the similar drug of the database (in green).
 screenshot of similarity results
 Images can be shown at a higher resolution by clicking on them.
 Results can be downloaded in a pdb document. This is an easy task that can be performed by clicking on pdf link at the top rigth of the table of results.

Nominal model for the optical response of a chiral sculptured thin film infiltrated by an isotropic chiral fluid-oblique incidence
J. A. Sherwin, Akhlesh Lakhtakia
Research output: Contribution to journalArticle
10 Scopus citations
Abstract
Numerical calculations on the response of a nonaxially excited chiral sculptured thin film (STF) infiltrated with a chiral fluid are presented. The effects of the constitutive and microstructural parameters on the optical response of the chiral STF are explored. Two Bragg regimes manifest themselves when the chiral STF is excited nonaxially. Infiltration of a chiral STF with a chiral fluid can either blue- or red-shift the spectral location of one Bragg regime, but the shift of the spectral location of the other Bragg regime is largely indifferent to the chirality of the fluid. The model also predicts that the chiral fluid can either enhance or diminish the optical activity exhibited by the chiral STF within either manifested Bragg regime. Which of these effects occurs depends on the microstructural and constitutive properties of the chiral STF as well as the constitutive properties of the chiral fluid. The angle of incidence of the plane wave also effects the response of the chiral STF.

Scripts vs. Functions
Program files can be scripts that simply execute a series of MATLAB® statements, or they can be functions that also accept input arguments and produce output. Both scripts and functions contain MATLAB code, and both are stored in text files with a.m extension. However, functions are more flexible and more easily extensible.
For example, create a script in a file named triarea.m that computes the area of a triangle:
b = 5;
h = 3;
a = 0.5*(b.* h)
a =
function a = triarea(b,h)
a = 0.5*(b.* h);
a1 = triarea(1,5)
a2 = triarea(2,10)
a3 = triarea(3,6)
a1 =
a2 =
a3 =

Obsessed with Absinthe
Absinthe Alcohol was invented in 1797 by Dr. Pierre Ordinaire. It is an anise-flavoured spirit derived from herbs, including the flowers and leaves of the herb Artemisia absinthium, commonly referred to as "grande wormwood", together with green anise and sweet fennel. By the 1800′s it quickly became one of Europe's most popular alcoholic drinks. It is very bitter (due to the presence of absinthin) and is therefore traditionally poured over a perforated spoonful of sugar into a glass of water. The drink then turns into an opaque white as the essential oils precipitate out of the alcoholic solution.

We have some Lambdas triggered by SQS queues. The Lambdas do intensive inserts into DynamoDB tables. The DynamoDB tables have autoscaling write capacity.
On peak loads, many numbers of messages come to Lambdas and they start to fail with ProvisionedThroughputExceededException. The DynamoDB needs minutes to scale up.
We expect when the Lambda fails the messages return back to SQS and are processed again after visibility timeout. This looks correct because later DynamoDB is scaled up and should be able to handle the grown writes.
However, we see a strange thing. When the number of execution errors for Lambda grows up, the SQS trigger is automatically disabled. The Lambda stops executions, the messages are accumulated in the queue.
Manual enabling of the trigger causes even more failures because DynamoDB is still not scaled up, but the number of messages to process from the queue was dramatically increased.
Only manual increasing the write capacity of DynamoDB helps.
Why the SQS trigger disables? This behavior is not documented.
How to avoid the trigger disabling?
In general, what is the recommended way to do a "backpressure" to limit the speed of polling the messages from SQS by a Lambda?
 - Even more upset: the Lambda may fail not only because of errors in my code but just because it's redeployed or needs to increase the concurrency. – gelin Apr 29 at 13:22
 - AWS support says the trigger was disabled because of incorrect Lambda permissions. Actually, in our case, the AWSLambdaVPCAccessExecutionRole was missing. However, our Lambdas were executed successfully, in 99% of cases... Asking the support where to find why the trigger was disabled... – gelin May 7 at 11:14

I'm not sure why the Lambda stops working. I suspect Lambda service notices that it keeps failing so it temporarily suspends it. Not sure.
You can try a number of workarounds:
 - Use DynamoDB on demand capacity - AWS says it scales instantly.
 - Alternatively if you use provisioned capacity and get the Provisioned Throughput Exception don't actually abort the Lambda execution but instead re-insert the message to the SQS queue and exit successfully. That way Lambda service won't see any failures and no SQS messages will get lost either.
Something along these lines could help :)
 - The second approach is actually what I did. Unfortunately, this doesn't work well if you have write multiplication in Lambda. For example, in one of my cases, each input message makes 12 writes to DynamoDB. If any of the write fails, I need to repeat all 12, which increases the load of DynamoDB even more, etc... I've added another queue for delayed write operations and another Lambda to apply those operations without the multiplication. – gelin Apr 30 at 4:59
 - Unfortunately again, Lambda may fail and FAILS because of issues in Lambda service itself, not my code (I don't see any exceptions in logs, but see failed executions of Lambda). And SQS trigger may be disabled in this case too. I've solved this (hope, temporary) by adding the Lambda which checks all SQS event sources in the account and enables them if they're disabled every 3 minutes. – gelin Apr 30 at 5:05

AWS support says the trigger can be disabled because of the insufficient permissions for the Lambda execution role.
My question:
Where the conditions when the Lambda trigger can be automatically disabled are documented? Or where to find why the trigger was disabled (some kind of Lambda service logs)?
AWS support answer:
Currently, there is no such public documentation which mentions the possible reasons for the Lambda trigger being disabled automatically. However, as I mentioned earlier, the most probable reason for the SQS Lambda trigger being disabled is that the Lambda function execution role does not have one or more of the following required permissions:
 - sqs:ChangeMessageVisibility
 - sqs:DeleteMessage
 - sqs:GetQueueAttribute
 - sqs:ReceiveMessage
 - Access to relevant KMS keys
 - Any applicable cross account permissions
 - Also, if the lambda function is in VPC, then the Lambda function should have all the permissions to list, create and delete the ENIs
Also, the reason for the trigger being disabled will not be mentioned in the Lambda function logs. So, I request you to please make sure that the Lambda function execution role has all the required permissions. If the Lambda function execution role has all the required permissions, the SQS trigger should not get disabled automatically.
In my case we actully missed the VPC permissions, i.e. we didn't attach the AWSLambdaVPCAccessExecutionRole policy to the Lambda execution role. (I have no idea how Lambda worked without this policy). Five days passed since we've fixed the roles, no trigger was disabled. So, it works.
As for DynamoDB and "backpressure", the idea of MLu is correct.
If you have only one write to DynamoDB per each SQS message, you can just fail in Lambda if the write fails. The message stays in SQS and will be received by the Lambda again after the visibility timeout. It's better to use the batch size of 1 to process the messages one by one in this case.
If you have multiple writes to DynamoDB per each SQS message (the write multiplication), the better is to catch ProvisionedThroughputExceededException in the Lambda and put the failed writes to another queue with delay to repeat them later by another Lambda. Note, it's important to repeat every single write, not the original message.
The dataflow will be like this:
dataflow with delay queue
Note, any delayed repeating of the writes are acceptable only if you really can delay and repeat them. They should be idempotent and should not contain real-time data. Otherwise, it can be better to silently ignore any exceptions, to avoid Lambda failure, and so, remove and forget the message from SQS.

text: Throughout the past two years, we've shown you various Walt Disney propaganda films from World War II. Now it's time to visit a very different mid-1940s Disney production – The Story of Menstruation. From 1945 to 1951, Disney produced a series of educational films to be shown in American schools. How to bathe an infant. How not to catch a cold. Why you shouldn't drive fast. Disney covered these subjects in its educational shorts, and then eventually got to the touchy subject of biology and sexuality. If there was ever a company suited to talk about "vaginas" in the 1940s in a copacetic way, it was Disney. Hence The Story of Menstruation. The film runs 10 minutes, combining scientific facts with hygiene tips, and it was actually commissioned by the International Cello-Cotton Company, the forerunner of Kimberly-Clark, the maker of Kotex products. An estimated 105 million students watched the film in sex ed classes across the US. And, according to Tinker Belles and Evil Queens, the film remained a mainstay in schools until the 1960s. It's now in the public domain. And you'll find it in the Animation section of our collection of 475 Free Online Movies.

FABRICATION, INSTALLATION, TEST AND EVALUATION OF MOTORCYCLE CONTROLS AND DISPLAYS; GEAR POSITION INDICATOR, NON-LINEAR THROTTLE, TACTILE INDICATOR OF NEUTRAL POSITION
A study was directed toward developing a greater margin of safety for motorcycles on the modern highway, reflecting adequate consideration of the physical and perceptual capabilities and limitations of the operator in order to achieve the optimum in system safety and performance. The study was concerned with two of the more critical motorcycle control/display areas: the throttle control and the gear position indicator. Undesirable features of present designs were identified and innovative designs were developed which modified the undesirable aspects of present designs. These devices were fabricated, installed, and tested on a GFE Honda test motorcycle.

API responses generally contain content in one language/translation. The API user can request a language by passing an Accept-Language header.
In special cases where the frontend can't really pass HTTP headers to the API, like when a HTML response should be displayed in an iframe, then the endpoint may also take a
lang query parameter with the same syntax as the

In case the API returns an error it is recommended to use the contained

Place the dish under the dissecting microscope and remove any fatty or connective tissues from the ascending and descending aorta. See Figure 3. Separate the ascending and descending aorta by making a cut just distal to the origin of the left common carotid artery. Put ascending and descending aorta separately in new dishes with DPBS labeled according to the region of the aorta and the genotype of the mouse.
 9. Working quickly but carefully, repeat for each experimental mouse until all the tissue has been separated. Pool ascending aortas and descending aortas for each explant.
 10. Move all the dishes with aortic tissue to the tissue culture hood.
 Figure 3. Appearance of the dissected aorta. Whole mount image showing the aortic tissue after it has been removed from the mouse and completely cleaned. Ascending aorta is marked by a red arrow.
 3. Explanting of the tissue
 Note: Please note that all steps for the rest of the protocol should be carried out under a tissue culture hood using standard sterile tissue culture techniques.
 1. Prepare the enzyme mix
 1. Thaw one aliquot each of collagenase and trypsin inhibitor at 4 °C before beginning the dissection of the mice.
 2. For each explant, use 5 ml of aorta biopsy storage media. If you are doing a 3-4 h digestion during the day, add 250 µl collagenase, 100 µl trypsin inhibitor, and 324 µl* elastase for each 5 ml of aorta biopsy storage media. For an overnight (15-18 h) digestion, use 1:10 dilution so 25 µl collagenase, 10 µl trypsin inhibitor, and 32.4 µl* elastase.
 *Note: The amount of elastase to add was calculated based on the mass and volume of the bottle. If you order elastase from a different source, you will need to recalculate the amount of this enzyme to add.
 2. Pour 70% ethanol, DPBS, and aorta biopsy storage media into three separate 60 mm tissue culture dishes.
 3. Using forceps, take each isolated aorta from its storage tube and wash the piece of tissue in ethanol, then DPBS, then biopsy media. Do not leave the tissue in ethanol for more than about 10-15 sec, though leaving it in DPBS or media for longer is OK.
 4. Place each piece of tissue into the lid of a 60 mm tissue culture dish. Using a scalpel and forceps, cut tissue into small pieces-make sure to cut the tissue both circumferentially and longitudinally to increase the surface area exposed to the digestion mix. The pieces will be variable in size, but the average size should be 1-2 mm in diameter.
 5. Place the chopped up tissue pieces into a new 60 mm tissue culture dish containing the 5 ml of media plus digestive enzyme mix made up in step C1. Label the dish.
 6. Place dish into incubator (37 °C). If doing a 3-4 h digestion, check at 2 h and every 30 min thereafter. If doing an overnight digestion, leave overnight, check at 15 h and every hour thereafter.
 7. When the tissue looks mostly digested with several floating single cells, but still some large clumps of tissue, pipet up and down tissue and media 5-10 times using a 10 ml pipet to help release cells from tissue. Place back into incubator for 30 more minutes. Also, remove filtered FBS from fridge to warm up to room temperature and place complete SmBM media into water bath to warm up to 37 °C.
 8. At the end of incubation time, look at tissue under microscope to make sure that the cells are free from the tissue. See Figure 4. If the tissue has been well digested (there should still be some intact pieces of tissue), add 2.5 ml of Serum and pipet up and down ~5 times. Next add 2.5 ml of complete SmBM media and pipet up and down ~5 times.
 Figure 4. Appearance of the digested tissue. Photo of the dish after digestion, with some 'net-like' tissue floating in it (black arrow) but a majority of tissue pieces digested.
 9. Transfer the entire contents of the tissue culture dish (should be 10 ml total) into one 15 ml tube.
 10. Spin down at 180 x g (about 700 rpm in a Sorvall Legend T+ tabletop centrifuge) at room temperature for 5 min.
 11. Carefully check to see if there is any floating tissue piece in the tube. If so, use a 200 µl pipette to remove the tissue piece and place it directly into a labeled T25 flask with complete SmBm. Once there are no tissue pieces floating, remove supernatant and resuspend the pellet in 5 ml of complete SmBM media.
 Note: If the supernatant was cloudy, repeat steps C10 and C11 until the supernatant is clear. If the supernatant was clear, proceed to step C12.
 12. Transfer the 5 ml complete SmBm with resuspended cells to a labeled T25 flask. Place flask in incubator.
 13. Allow cells to settle and adhere to the flask. Don't change media for at least 48 h. If cells still haven't settled down at this point, don't remove any media and add 2 ml of media to the flask. Let the cells settle for another 1 to 2 days.
 4. Maintenance and subculture of mouse vascular smooth muscle cells.
 1. Once SMCs grow up, feed the cells with fresh media every 3-4 days.
 1. Prewarm the SmBm complete media bottle in a 37 °C water bath for at least 15 min prior to feeding cells.
 2. Aspirate media from each flask and discard.
 3. Add 5 ml of media for each T25 flask without disturbing the cell layer.
 4. Return flasks to the incubator.
 2. When the cells reach about 70% confluent, or when some areas start to get very tightly packed and almost overgrown, the cells are ready to split. See Figure 5. Passage the SMCs from one T25 flask to one T75 flask.
 1. Prewarm the SmBm complete media bottle in a 37 °C water bath and allow the TrypLE Express reagent to equilibrate at room temperature for at least 15 min prior to splitting cells.
 2. Aspirate media from each flask and discard.
 3. Wash each flask once with 4 ml of DPBS, allow it to cover the cell layer, then aspirate and discard the DPBS.
 4. Add 1 ml TrypLE Express reagent to each flask. Make sure the trypsin is evenly covering the bottom of the flask/cell layer.
 5. Place the flask in the 37 °C incubator for 3 min.
 6. Confirm digestion under microscope. If most cells are round, bang the flask twice on both sides. If most cells are still attached incubate at room temperature for 1 min and then confirm digestion and bang the flasks twice on both sides.
 7. Add 4 ml of SmBm complete to each flask to neutralize the trypsin enzyme. Pipet up and down to detach all the cells and completely neutralize the enzyme.
 8. Transfer all 5 ml of liquid plus cells to a 15 ml conical tube.
 9. Spin down 5 min at 180 x g in a tabletop centrifuge at room temperature.
 10. Aspirate supernatant, resuspend cell pellet in 10 ml of SmBm complete, and transfer all 10 ml to a labeled T75 flask. Mark the date of split and the passage number (P1 for this first passaging).
 Figure 5. Appearance of confluent SMCs. The left picture shows a 100% confluent field of smooth muscle cells. These cells need to be passaged within 24 h. The right panel shows smooth muscle cells around 70% confluent. Note the spindle-shaped morphology which is characteristic of SMC cultures.
 3. When the SMCs have expanded, the cell aliquots can be frozen. Follow steps D2a-D2i in the above protocol for passaging SMCs. One T75 flask can be split into 2 frozen cell aliquots. A confluent T75 flask should have around 2 million cells, so each freeze vial will have around 1 million cells. After spinning down, follow the below steps to freeze cells.
 1. Aspirate supernatant, resuspend cell pellet in 3 ml SMC freeze media (see Recipes).
 2. Transfer 1.5 ml of the freeze media with dissolved pellet to each of two cryovials. Cryovials should be labeled with the passage number, date of freezing, and cell line.
 3. Place cryovials into a slow freeze container (either a foam container or an isopropanol based container will work) and freeze in the -80 °C freezer overnight.
 4. Transfer the frozen aliquots to a liquid nitrogen storage system for long-term storage.
 4. When you want to thaw your SMC aliquots, a vial of frozen cells can typically be thawed to one T75 flask.
 1. Prewarm Sm

We consider a tactical data network with limited bandwidth, in which each agent is tracking objects and may have value for receiving data from other agents. The agents are self-interested and would prefer to receive data than share data. Each agent has private information about the quality of its data and can misreport this quality and degrade or otherwise decline to share its data. The problem is one of interdependent value mechanism design because the value to one agent for the broadcast of data on an object depends on the quality of the data, which is privately known to the sender. A recent two-stage mechanism due to Mezzetti (2004) can be modified to our setting. Our mechanism achieves efficient bandwidth allocation and provides incentive compatibility by conditioning payments on the realized value for data shared between agents.

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.

 Abstract
 The water vapor permeance is defined as a ratio of the water vapor transmission of a body between two specified parallel surfaces, to the water vapor pressure difference between the two surfaces. Since water vapor pressure differential across a film is the principal driving force in water vapor diffusion through the film, the transmission rate through any particular film should have a linear relationship to the difference in relative humidity across the film for any fixed temperature condition. This linear relationship can only be true if the coating has no interaction with the water molecules passing through the film, and the film remains unchanged by relative humidity conditions.
 Test data are presented showing that for various coating compositions there is an interaction with moisture passing through the film, which is dependent upon each film's particular water sensitivity and absorption. This interaction is shown to result in a non-ideal behavior, with the permeance not being independent of relative humidity conditions. Rather the permeance was found to increase with an increasing relative humidity differential across the film.

Lane Targeting Light
The Torch is a simple light targeting tool used to help with accuracy and alignment. Using LED lights, it reflects a path of light on the lane to help you select the correct launch angle and hit your target time after time. As the player moves left and right, the light will change its position showing you exactly where you should throw the ball.
The Torch was designed to explain the aiming process in a way that can be easily understood by everyone. From children, to beginning bowlers, to special needs bowlers, the Torch is an easy and fun way to quickly improve this important fundamental skill.
- Helps define a bowlers starting point
- Helps bowlers to see the laydown point
- Helps keep the swing path in-line with the target path
- Helps keep the head stable throughout the approach
- Shows how the target changes if a bowler drifts left or right

 4. Conclusion
Introduction
The String.subSequence() method is a member of the String class in Java. It allows you to retrieve a portion of a string as a CharSequence from the specified start index to the end index (exclusive). This method is particularly useful when you need to work with a portion of a string without creating a new string object.
subSequence Method Syntax
The syntax for the subSequence method is as follows:
public CharSequence subSequence(int beginIndex, int endIndex)
 - beginIndex: The beginning index, inclusive.
 - endIndex: The ending index, exclusive.
Examples
Extracting a SubSequence
The subSequence method can be used to extract a portion of a string as a CharSequence.
Example
public class SubSequenceExample {
 public static void main(String[] args) {
 String message = "Hello, World!";
 CharSequence subSequence = message.subSequence(7, 12);
 System.out.println("Original message: " + message);
 System.out.println("SubSequence from index 7 to 12: " + subSequence);
 }
}
Output:
Original message: Hello, World!
SubSequence from index 7 to 12: World
Handling Edge Cases
The subSequence method can handle edge cases such as extracting subsequences at the bounds of the string. However, it will throw an IndexOutOfBoundsException if the specified indices are out of range.
Example
public class SubSequenceExample {
 public static void main(String[] args) {
 String message = "Hello, World!";
 // Valid range
 CharSequence subSequence1 = message.subSequence(0, 5);
 CharSequence subSequence2 = message.subSequence(7, message.length());
 System.out.println("SubSequence from index 0 to 5: " + subSequence1);
 System.out.println("SubSequence from index 7 to end: " + subSequence2);
 // Invalid range
 try {
 CharSequence invalidSubSequence = message.subSequence(7, 20);
 System.out.println("SubSequence from index 7 to 20: " + invalidSubSequence);
 } catch (IndexOutOfBoundsException e) {
 System.out.println("Error: " + e.getMessage());
 }
 }
}
Output:
SubSequence from index 0 to 5: Hello
SubSequence from index 7 to end: World!
Error: begin 7, end 20, length 13
Comparison with substring
The subSequence method returns a CharSequence, whereas the substring method returns a String. Both methods work similarly, but subSequence is more general and can be used in contexts where a CharSequence is required.
Example
public class SubSequenceExample {
 public static void main(String[] args) {
 String message = "Hello, World!";
 CharSequence subSequence = message.subSequence(7, 12);
 String substring = message.substring(7, 12);
 System.out.println("SubSequence from index 7 to 12: " + subSequence);
 System.out.println("Substring from index 7 to 12: " + substring);
 // Verify they are equal
 boolean areEqual = subSequence.toString().equals(substring);
 System.out.println("Are SubSequence and Substring equal? " + areEqual);
 }
}
Output:
SubSequence from index 7 to 12: World
Substring from index 7 to 12: World
Are SubSequence and Substring equal? true
Conclusion
The String.subSequence() method in Java is used for extracting portions of a string as a CharSequence. By understanding how to use this method, you can efficiently work with parts of strings without creating new string objects. Whether you are handling edge cases or comparing it with the substring method, the subSequence method provides a reliable solution for these tasks.

I have made a simple script here to move the points branches of a divided surface towards the z direction using a graphmapper as show to achieve a sort of curtain effect.
It works fine on a flat surface but once I apply it to the adjacent freeform surface it will fail obviously becos of the direction of movement.
I would hope to make the points move in the same way as the Graphmapper but following the surface curvature and isocurve (V) direction.
Would any experts there have any advice for me please?
Please find the attached file for your reference.
Thank you so much!
Thank you so much, I see that you have moved the points in the Normals direction which produced an offsetted result and what I really need is to move them along the curve surface so they produce a draw curtain effect on the freeform surface.
I have attached the image I need to achieve, which is done by morph. You can see that the points should move along the surface according to the Grahmapper. I just wonder if you would know a way to make this translation on the actual surface instead of using morph (made from a flat surface)?
Thank you so much its almost there, if you see my image and also the original flat surface, at the end of the surface, the curves will merge upwards which produces a partial open curtain effect. Can this be achieved? Thanks!


Assistant Professor Receives National Endowment for the Humanities Fellowship

Dennis Britton, assistant professor of English
Dennis Britton, assistant professor of English, has been awarded a yearlong National Endowment for the Humanities Fellowship at the Folger Shakespeare Library in Washington, D.C. The fellowship will allow him to complete research and make final revisions to his current book project, "Becoming Christian: Race, Reformation, and Early Modern English Romance."
Britton's monograph is the first to explore the role of race in the Church of England's baptismal theology and literary representations of "infidels"—specifically Jews, Turks, and Moors—converting to Christianity in early modern English romance. Catholic romances emphasized baptism's magical power to transform infidels into faithful Christians. However, theologians within the Church of England denied the miraculous power of baptism, even debating whether or not it was necessary for salvation. In fact, many English theologians asserted that salvation could be assured by one's race and lineage. Britton contends that baptismal theology and emerging concepts of race provide a not-yet-recognized context for understanding why works such as Edmund Spenser's "The Faerie Queene" and William Shakespeare's "Merchant of Venice" and "Othello" transform and, at times, explicitly reject the infidel conversion motif.


Old-New Synagogue
Staronová Synagóga
2 votes 2 votes
The Old-New Synagogue (Staronová Synagóga), built around 1270, is the oldest functioning synagogue in Europe. It is also one of only three synagogues in Prague's Jewish Quarter 'Josefov' still used for services.
The rather small building in early gothic style consists of one central hall bordered by a number of smaller rooms. The vaulted hall is supported by two octagonal pillars. Only men are allowed to attend services in the
Old-New Synagogue, Prague
Old-New Synagogue
central hall, women can access the rooms near the hall. Small windows in the wall, added in the 18th century, allow the women to view the services.
Angelic Protection
It is almost a miracle the synagogue has survived until today. During its more than 700 years of existence, the building has survived several pogroms, fires and a 19th century redevelopment of the Jewish quarter.
Legend has it that the synagogue is protected by Angels who brought the stones to build the synagogue from the ruins of King Solomon's Temple. In time the synagogue will be dismantled and the stones will be used to rebuild the temple in Jerusalem.
The Name
The same legend gives an explanation for the building's strange name: it would be an incorrect translation from its Hebrew name 'At-Tnay Synagogue'. Misinterpreted as alt-neu (old-new in English), it literally means 'on condition', meaning that the synagogue only exists conditionally - until the Jews return to Jerusalem and rebuild the Temple of Solomon.
A much easier explanation for the name could be that the original name 'New Synagogue' was changed in the 16th century into 'Old-New Synagogue' after newer synagogues were built.
The Old-New Synagogue is located in the center of Josefov, the Jewish quarter just north of Old Town.

sample sentence:
the words that could be ambiguous are
项目: the project
目的: the goal, purpose, aim, intent
how can this be resolved?
 - 1
 depends on which grouping ("parsing") makes sense, 这个｜项｜目的 does not seem to make sense, b/c there already is CL 个，so 项 would have an attributive meaning, which seems implausible, incidentally ［项］［目的] raises the question whether 项 can be used as CL of 目的，but e.g. 小马词典 has 个 as CL, presumably 种 would also be acceptable, but 项 sounds unusual, anyhow there already is 个 and there cannot be 2 CL in a row for the same noun – user6065 Sep 14 '18 at 23:04
If you treat 目的 as a noun, then 项 has to be a classifier. But there's already a classifier 个 before it, (项 is not the right classifier for 目的 anyway), therefore, we can eliminate the possibility of "目的" in this sentence being a noun. Which mean 项 is not a classifier but a part of the compound word 项目 (item)
It all make sense, because we know "个" is a classifier for "项目" (item)
"项" itself is a classifier, but it doesn't work with "目的"(goal) (the classifier of 目的 is 个)
在这个项目(的)研究上 = about the study on this item
的 is an adjective marker that turn 这个项目 into an adjective phrase "这个项目的" for the noun 研究 (study) - what study? this item's study

Yes, for example, the following sentence can be interpreted differently depend on where you slight pause between words
"是個 人用的 工具" = "是個 (is a) 人用的 (for human use) 工具 (tool)" = "is a tool for human use"
"是 個人用的 工具" = "是" (is) 個人用的 (for personal use) 工具 (tool)" = "is a personal used tool"
Both examples are grammatically correct, you have to listen to how it is read to determine it is "是個. 人用的" or "是. 個人用的"
Or you can look for hints in the context to determine the correct interpretation
One fun one, but it has to do with punctuation marks:
1. 下雨天留客, 天留人不留 (It is raining as if the heaven wanted to keep the guest here, but the host doesn't keep the guest even the heaven does)
2. 下雨天, 留客天, 留人不? 留! ("It is a rainy day, it is a day to keep the guest, do you keep the guest?" "Yes I do!"
 - is there a more ambiguous kind of sentence? surely there must be, that's more of what I'm trying to get at but I appreciate your answer. thank you for taking the time to do it! – Lenny Sep 15 '18 at 1:06
 - _USER_ yes, just read my edition at the bottom – Tang Ho Sep 15 '18 at 1:32
 - Thank you very much, you are amazing. You deserve lots of points. – Lenny Sep 15 '18 at 6:01
There is no ambiguity of your sentence. All least in 简体中文 for Mandarin, one character will never be used by two words (It might happen as rare case in spoken language, but is often considered as mistakes(lazyness?) and definitely wrong in the writing system ).
According to this rule, does 这个|项|目的|研究上 make any sense to you? As a native speaker, I don't think it make any sense.
So the rule of word group, if it makes sense, then it works. For ANY human language. And yes, ambiguity can happen (in ANY human language) as you can see in other answers, but not like this.

USE OF AERIAL PHOTOGRAPHS IN THE STUDY OF NATURAL HAZARDS
The interpretation of vertical aerial photographs has proved to be an effective technique in the preparation of environmental-engineering-geologic maps. No other technique can provide a three-dimensional overview of the terrain from which the inter-relations of topography, drainage, surface cover, geologic materials, geologic structure, geohazards and human activities on the landscape can be viewed and evaluated.
The purpose of this exercise is to introduce you to the techniques of aerial photointerpretation and preparation of an environmental-geologic map of Harbour View area, St.Andrew, Jamaica.
2. PRINCIPLES OF ANALYSIS:
EXAMINE THE PHOTOGRAPHS PROVIDED WHILE YOU READ THIS SECTION.
See SHEET # 1 for basic principles of aerial photo-interpretation. This will help you to set the photos for stereoscopic viewing.
The interpretation of aerial photographs involves:
a. Examine the photographs to get a 3-D perception,
b. Identify ground conditions by observing certain elements appearing in the photographs and
c. Using photo-interpretation techniques, analyze specific problems by the association of ground conditions with interpreter's experience.
The quality and reliability of interpretations is improved by subsequent field checks, which is an essential component of all mapping projects.

Re: Use Regular Expression to add spaces to a string

in reply to Use Regular Expression to add spaces to a string
Part of what you MUST do when writing a regex is to describe the transformation you want in English. An example is not enough. You might see the transformation as obvious, but we can't, and your regex certainly can't tell what you're thinking.
It seems that what you're wanting to do is this: "Take a nine-character string and change it into the first three characters, followed by a space, followed by the second three characters, followed by a hyphen, followed by the last three characters."
If that's what you want, you write it like this.
$str =~ s/^(...)(...)(...)$/$1 $2-$3/';
But that will also translate "bookstore" into "boo kst-ore". Is that OK? Or do you only want to do transformations if there are digits? Then you have to write it as:
$str =~ s/^(\d\d\d)(\d\d\d)(\d\d\d)$/$1 $2-$3/';

A Laboratory of Possibilities project
Ecological transition can be entirely undergone or partially chosen
Acceleration of climate change, collapse of biodiversity, depletion of natural resources: everyone today has heard about the rapid, profound and irreversible changes in the conditions of life on the planet.
In the light of the unprecedented ecological crisis facing humankind, Université de Montréal and Space for Life have joined forces to present Transition Pathways, a project for involving the vital actors of society in the necessary debate on transition in Québec.
Transition Pathways is structured around three major challenges
In the framework of the Transition Pathways project, transition issues are approached in the form of three major challenges calling into question our ability to develop and flourish within the limits of the planet:
- Food challenge
How can we ensure that more and more people have access to a healthful diet without depleting the earth's resources in a context of climate change?
- Land-use challenge
How can we live in Québec in a restrained and resilient way, in a context of ecological transition?
- Digital challenge
How do we go about merging the digital and ecological transitions?
Citizen participation: an essential element in Transition Pathways
Transition Pathways is a knowledge mobilization project, one that draws together learning of all types. Citizen participation is solicited throughout the project, in particular for citizens' workshops.
These workshops allow interested parties, in the company of other citizens, to reflect and to discuss their priorities with respect to each of the challenges under discussion as well as the conditions that would make their personal actions easier.
Citizens' food challenge workshops
The land is fundamental for the future, especially in a climate-change framework. By 2050 it will have to ensure food security to 10 billion human beings, contribute to reducing our CO2 emissions, and allow for the maintenance of a sufficient level of biodiversity – all this at the same time.
It is crucial to build a new food system in Québec, one that will make it possible to feed the population in a healthful way and to restore ecosystems, the source of our food.
Digital challenge workshops
A series of workshops aimed at identifying ways of making the use of digital tools with a net environmental gain more attractive and limiting the use of those with the highest impact was held in the fall of 2020.
About Transition Pathways
"Transition Pathways" designates models of change that society follows, voluntarily or not. Those pathways are many, and produce different trajectories of change. They involve collective choices to respond to identified issues and may be economic, social, technological, institutional or cultural in nature.
The Transition Pathways project harnesses the knowledge of several disciplines in order to identify the choices that have the potential to lead Québec society towards a desirable future, among the many possible futures.
What choices will help steer Québec society towards a desirable future?
In order to collectively identify the pathways with the greatest potential to take Québec on the most desirable trajectory, transition issues are addressed by way of the project's three challenges: the food challenge, the land-use challenge and the digital challenge.
For each of these challenges, a four-phase approach extending over a period of a year and a half makes it possible to bring together a diversity of experts, role-players and citizens with a view to mapping out the paths with the greatest potential.

The energy profile study of electric kitchen utensils for residential smart kitchen
To be more cost effective and environmental friendly, electric cooking is a new trend in both commercial and residential use. Utility states that electric cooking can reduce 20% to 50% energy cost in all kinds of restaurants. However, widely adoption of electric cooking would make a heavy load on energy supply. Also, some buildings with old energy system standard may not be able to support the large energy demand caused by electric cooking. The understanding of energy usage pattern of electric cooking is important to tackle with this potential problem. An energy profile of electric kitchen utensils is essential to minimize the energy demand. This paper gives the overview of the recent market growth in electric cooking and also introduces the potential wireless sensor network technology for energy auditing in smart kitchen. Even more important, this paper analyzes the energy usage of electric kitchen utensils such as stove, microwave oven, refrigerator and freezer. An experiment would be set up by using the existing energy auditing system. The energy consumption pattern of each kitchen utensil is collected with current transformer which will be displayed as instant consumption reading. By using the collected consumption data, energy profile of each electric kitchen utensil can be generated. Having the energy profile of each electric kitchen utensil is critical to the real time energy demand forecast and so helps the utilities conduct the energy demand response effectively.
