!! Context
Buildings design takes great advantages of simulation, for instance to improve fire safety or optimize the space. Initiated with [[Alstom|http://www.alstom.com]] for the design of underground trains, the objective of this project was to simulate pedestrians in crowded areas, taking into account individual characteristics such as speed or body type. It took place in 2006 in the [[Multi-Agents Systems and Behavior Team|http://www.lifl.fr/SMAC/]] of the [[Computer Science Laboratory of Lille|http://www.lifl.fr]].

!! Issues
Our objective was to simulate pedestrians displacement through complex environments.The objective was to reproduce real world situations, not to obtain the most realistic appearance. Three main issues were thus considered:
# space management: pedestrians and environment representation, displacement models
# time management: scheduling, waiting queues
# and simulation validation: confronting the simulation results with reality, at the macroscopic leve (flows at entrances or exits, statistic distributions) and at the microscopic level (individual behaviors)
!! Results
[>img(40%, )[The MISC platform: simulated crowd in a corridor|images/misc_corridor.png][images/misc_corridor.png]] The work led to the development of the MISC platform (for “Modeling of Individuals in Spatialy Constrained environments”). MISC allows simulating agents, here pedestrians, in complex environments.
The agents use collision algorithms, and autonomously adjust their movements according to their individual characteristics and limited perceptions. Our approach use the notion of agents' generators. Those generators create various agents' at specified intervals and frequency, and assign them global objectives and individual characteristics.
One of the hard issues considered in the project was to allow agents to switch their displacement model at runtime, so as to handle point-to-point displacement as well as queuing at a ticket distributor. The displacement model is based on the concept of blurred path following, coupled to a model of waiting queues. An agent is thus able to move halfway to its final goal, wait a few minutes, and then complete its journey.
Finally, validation is based on flow measurements, the next objective being the integration of individual behavior and valication with real data.

!!Issues
In buildings, the thermal functions of heating, ventilation, air conditioning and domestic hot water production are often interdependent. Additionally, it is more and more complex to control them, given the increasing use of alternative energy sources, such as solar thermal collectors or heat pumps. In this project, we elaborated an approach allowing to design and optimize the control of thermal systems in the buildings, while improving flexibility and reusability.
!!Results
The details of the proposed solution are still confidential. They will be published mid-2012, after patent application has been filled.
[>img(, )[The prototype compact unit controlled using the proposed approach|images/prototype_compact_unit.png]]The approach was used to control a compact unit providing heating, ventilation and domestic hot water production in a low-energy building. The system was evaluated using a thermal simulator, and managed to improve the thermal comfort by 35% compared to the initial control system, for only a 2.5% increase in costs. The approach will soon be evaluated on a physical test bench to validate these results in experimental conditions.

|Version|1.2.1|
|Author|Eric Shulman|
|License|http://www.TiddlyTools.com/#LegalStatements|
|~CoreVersion|2.1|
|Type|plugin|
|Description|adds support for resizing images|
This plugin adds optional syntax to scale an image to a specified width and height and/or interactively resize the image with the mouse.
!!!!!Usage
<<<
The extended image syntax is:
{{{
[img(w+,h+)[...][...]]
}}}
where ''(w,h)'' indicates the desired width and height (in CSS units, e.g., px, em, cm, in, or %). Use ''auto'' (or a blank value) for either dimension to scale that dimension proportionally (i.e., maintain the aspect ratio). You can also calculate a CSS value 'on-the-fly' by using a //javascript expression// enclosed between """{{""" and """}}""". Appending a plus sign (+) to a dimension enables interactive resizing in that dimension (by dragging the mouse inside the image). Use ~SHIFT-click to show the full-sized (un-scaled) image. Use ~CTRL-click to restore the starting size (either scaled or full-sized).
<<<
!!!!!Examples
<<<
{{{
[img(100px+,75px+)[images/meow2.jpg]]

|Type|plugin|
|Description|Show tiddlers one at a time with automatic permalink, or always open tiddlers at top/bottom of page.|
This plugin allows you to configure TiddlyWiki to navigate more like a traditional multipage web site with only one tiddler displayed at a time.
!!!!!Documentation
>see [[SinglePageModePluginInfo]]
!!!!!Configuration
<<<
<<option chkSinglePageMode>> Display one tiddler at a time
><<option chkSinglePagePermalink>> Automatically permalink current tiddler
><<option chkSinglePageKeepFoldedTiddlers>> Don't close tiddlers that are folded
><<option chkSinglePageKeepEditedTiddlers>> Don't close tiddlers that are being edited
<<option chkTopOfPageMode>> Open tiddlers at the top of the page
<<option chkBottomOfPageMode>> Open tiddlers at the bottom of the page
<<option chkSinglePageAutoScroll>> Automatically scroll tiddler into view (if needed)
Notes:
* The "display one tiddler at a time" option can also be //temporarily// set/reset by including a 'paramifier' in the document URL: {{{#SPM:true}}} or {{{#SPM:false}}}.
* If more than one display mode is selected, 'one at a time' display takes precedence over both 'top' and 'bottom' settings, and if 'one at a time' setting is not used, 'top of page' takes precedence over 'bottom of page'.
* When using Apple's Safari browser, automatically setting the permalink causes an error and is disabled.

!! Context
The project was held at Renault’s [[Technical Center for Simulation|http://www.experts.renault.com/kemeny/]], in partnership with the [[Multi-Agents Systems and Behavior Team|http://www.lifl.fr/SMAC/]] of the [[Computer Science Laboratory of Lille|http://www.lifl.fr]]. One of the missions of the Technical Center for Simulation is to develop and use driving simulators for study and research. These simulators are used for experiments in ergonomics, validation of embedded systems, comfort, or for the design and the validation of car lightings systems. The objective is to improve the drivers’ security, while reducing costs and delays in vehicles development.

!! Issues
In simulators, the driver is immersed in a simulated traffic, which realism is crucial for the validity of the results: the more realistic the environment is perceived, the more significant the drivers' reactions are. The wide range of drivers’ behavior is an important criterion for this realism: on the road, we are used to meet aggressive drivers, careful ones, etc.
In individual-centered approaches, like traffic simulation in our case, the agents' behavioral variety is an important realism criteria. The behaviors also have to be consistent: if aberrant situations appear, the simulation realism is strongly impacted. In this work, we adressed the issue of the simultaneous influence of these two elements. Furthermore, this work was led in an industrial context. This involved taking into account specific needs: the designed tools had to allow experts specifying various and consistent behaviors, and final users easily using them.
!! Results
In this work, we proposed a behavioral differentiation model, which provides the basis for a generic and non-intrusive tool allowing an out-of-the-agent design. The model involves three dimensions. First, it describes the agents' behaviors using norms. They provide a behavioral pattern during conception, and a compliance reference during execution. Then, the generation process of the behaviors allows the creation of deviant or violating agents, by influencing the determinism of the mechanism. Finally, the norms can be inferred from previous simulations records or real data, providing an analysis tool of the results and allowing automating the model con figuration.
We applied the model to the traffic simulation in [[SCANeR|http://www.scaner2.com]]™, the driving simulation software developed and used at the Technical Center for Simulation of Renault. The developments carried out during the thesis introduced driving styles in the traffic (e.g. cautious or aggressive drivers) specified using norms. The behavioral realism of the traffic was improved, and the experimentations show how the model contributes to the variety and the representativeness of the produced behaviors. Today, the behavioral differentiation model is part of the commercial version of the driving simulation software.
