Calibration of a micro simulation program for a Chinese city

Micro simulation programs are often used to assess the quality of traffic conditions. They are especially suited to evaluate possible control scenarios in advance, so that the scenarios can be selected and optimized before implementation. Of course, the simulation programs should be valid for the traffic situation that has to be modeled with...

Longitudinal Driving Behavior under Adverse Conditions: A Close Look at Psycho-spacing Models

Adverse weather conditions have been shown to have a substantial impact on traffic flow operations following substantial adaptation effects in driving behavior. In quantifying these effects psycho-spacing models may be used. In this contribution it was examined to what extend adverse weather conditions influence the position of action points in...

Effect of spatial heterogeneity of runoff generation mechanisms on the scaling behavior of event runoff responses in a natural river basin

This paper presents a theoretical investigation of the effects of spatial heterogeneity of runoff generation on the scaling behavior of runoff timing responses. A previous modeling study on the Illinois River Basin in Oklahoma had revealed a systematic spatial trend in the relative dominance of different runoff generation mechanisms,...

Psychological elements in car-following models: Mental workload in case of incidents in the other driving lane

Estimations of parameter values of car-following models show considerable differences between individuals and experiments. These differences may be caused by a different effect of external circumstances on mental workload of drivers. This effect may especially play a considerable role in case of driving under adverse conditions (e.g. evacuations...

Supplier websites: Could they be inspiring to lighting designers?

This paper describes an exploratory pilot study on the usefulness for designers of three lighting manufacturers’ websites. All three websites contain sections that are specifically directed at professional lighting designers. This study’s first objective is to investigate whether designers experience the websites' content as conducive to the...

Supply Chain Management and Sustainability: Procrastinating Integration in Mainstream Research

Research has pointed out opportunities and research agendas to integrate sustainability issues with supply chain and operations management. However, we find that it is still not mainstream practice to systematically take a sustainability approach in tackling supply chain and operations management issues. In this paper, we make use of behavioral...

Evacuation plan of the city of almere: Simulating the impact of driving behavior on evacuation clearance time

The evacuation clearance time is one of the key indicators in an evacuation plan and is determined by the expected behavior of the endangered residents and roadway network characteristics. The city of Almere has developed an evacuation plan in case of the emergency of a flooding, but assumes a normal driving behavior of the evacuees. In this...

Local control of cognitive radio networks

In a network deployment, a cognitive radio will have to perform two fundamental tasks. First, each cognitive radio needs to optimize its internal operation, and second, it needs to derive a configuration that will enable and optimize communication with other nodes in the network. This latter requirement, however, relies on knowledge about the...

A formal ontological perspective on the behaviors and functions of technical artifacts

In this paper we present a formal characterization of the engineering concepts of behavior and function of technical artifacts. We capture the meanings that engineers attach to these concepts by formalizing, within the formal ontology DOLCE, the five meanings of artifact behavior and the two meanings of function that Chandrasekaran and Josephson...

Role Identification of Yaw and Sway Motion in Helicopter Yaw Control Tasks

A set of experiments has been conducted to investigate the relative effect of translational and rotational motion cues on pilot performance. Two helicopter yaw control tasks were performed on the SIMONA: a yaw capture task and a target-tracking task with simulated turbulence. The yaw capture task was a repetition of a task performed previously...

A review of function modeling: Approaches and applications

This work is aimed at establishing a common frame and understanding of function modeling (FM) for our ongoing research activities. A comparative review of the literature is performed to grasp the various FM approaches with their commonalities and differences. The relations of FM with the research fields of artificial intelligence, design theory,...

Agent-oriented modeling of the dynamics of biological organisms

Numerical simulation of the LAGEOS thermal behavior and thermal accelerations

The temperature distribution throughout the LAGEOS satellites is simulated numerically with the objective to determine the resulting thermal force. The different elements and materials comprising the spacecraft, with their energy transfer, have been modeled with unprecedented detail. The radiation inputs on the satellites are direct solar ...

Error Resilient Video Compression Using Behavior Models

Wireless and Internet video applications are inherently subjected to bit errors and packet errors, respectively. This is especially so if constraints on the end-to-end compression and transmission latencies are imposed. Therefore, it is necessary to develop methods to optimize the video compression parameters and the rate allocation of these...
