Behavior

Summary

Behavior (American English) or behaviour (British English) is the range of actions and mannerisms made by individuals, organisms, systems or artificial entities in some environment. These systems can include other systems or organisms as well as the inanimate physical environment. It is the computed response of the system or organism to various stimuli or inputs, whether internal or external, conscious or subconscious, overt or covert, and voluntary or involuntary. Taking a behavior informatics perspective, a behavior consists of actor, operation, interactions, and their properties. This can be represented as a behavior vector. Models Biology Behavioral ecology Although disagreement exists as to how to precisely define behavior in a biological context, one common interpretation based on a meta-analysis of scientific literature states that "behavior is the internally coordinated responses (actions or inactions) of whole living organisms (individuals or groups) to in

Measurement and determinants of consistency across key pro-environmental consumption behaviours in EPFL community

Mehdi Tarik

This project focuses on the consistency and the reasons linked with some of the Environmental behaviors of EPFL community. A statistical and segmentation analysis will be performed, at first to investigate the consistency between people's behaviors and then to investigate the factors that influence the realization or not of these behaviors. This environmento-sociologic work will bring informations concerning EPFL's users, informations that could be reused in order to analyze new strategies for having a green campus and to adopt the best decisions for convincing people to adopt a more eco-friendly behavior.

Deposition Processes with Hardcore Behaviour

Particles are deposited onto a surface with discrete sites. They are subject to an inhibition by which they cannot pass close by a particle already fixed on the surface. This implies that the surface builds up with vertical gaps between the particles. In this paper it is shown that there is a limiting rate at which the surface grows, and that this is related to the "roughness" of the surface.

Steel concentrically braced frame (CBFs) are widely used as a laterally-resisting system in the case of seismic actions as they are generally easier and faster to erect, and in most cases, they cost less than moment-resisting frame system. However, special care must be made in the design of gusset plate connections as over the years, a great deal of steel structure has emphasized their importance through different types of failure. In this master project, the failure of a gusset plate connection from a steel concentrically braced frame is analyzed with finite element modelling. This CBFs was part of two-story parking garage structure where most of the braces oriented in the east-west direction had fractured at their gusset plate connections after the 2011 Tohoku Earthquake in Japan. With finite element analysis, the cause of the buckling of the gusset plate failure mechanism was explained. As a matter of fact, the concentration of stresses and inelastic deformation during cyclic loading, particularly when the brace was in compression, led to fracture in the gusset plate. The fracture initiation process was then predicted with the Cyclic Void Growth Model. Therefore, four retrofit schemes are proposed to rectify the poor behavior of the gusset plate. They are evaluated based on a static pushover analysis and the results have shown several issues that might arise depending on the modifications. It has been shown, that one of the retrofit scheme where the gusset plates are design using elliptical clearance theory provided the best results. The simulation showed that the brace could buckle in compression without having premature failure in the gusset plate as the brace end rotation capacity was high enough. This study shows the importance of a well thought connection design in a concentrically braced frame system and how can different retrofit concepts alter or improve their behavior. It is relevant to note that not every concept and ideas will provide the desired impact and consequences.
