In the present paper scalar macroscopic models for traffic and pedestrian flows are coupled and the resulting system is investigated numerically. For the traffic flow the classical Lighthill-Whitham model on a network of roads and for the pedestrian flow the Hughes model are used. These models are coupled via terms in the fundamental diagrams modeling an influence of the traffic and pedestrian ...

The main focus of this paper is demonstrating a methodology for capturing and designing co-operative work processes. We present a method, appropriate for group work analysis, and particularly well suited for the analysis and design of workflow applications. With this end in view, we have chosen the OSSAD method as a foundation for a specific method for co-operative applications analysis and des...

Dynamically reconfigurable computing systems (DRCS) provides an intermediate tradeoff between flexibility and performance of computing systems design. Unfortunately, designing DRCS have a high complexity and is a formidable task. Although many researches are ongoing in the academia and industry, but the lack of tools and design flows discourage designers from adopting the reconfigurable computi...

A simple yet efficient traffic flow model, in particular one that describes vehicle longitudinal operational control and further characterizes traffic flow fundamental diagram, is always desirable. Though many models have been proposed in the past with each having its own merits, research in this area is far from conclusive. This paper contributes a new model, i.e., the longitudinal control mod...

BACKGROUND Few studies have focused on the social inequalities associated with environmental noise despite its significant potential health effects. This study analysed the associations between area socio-economic status (SES) and potential residential exposure to road traffic noise at a small-area level in Marseilles, second largest city in France. METHODS We calculated two potential road no...

BACKGROUND Reporting of the flow of participants through each stage of a randomized trial is essential to assess the generalisability and validity of its results. We assessed the type and completeness of information reported in CONSORT (Consolidated Standards of Reporting Trials) flow diagrams published in current reports of randomized trials. METHODS A cross sectional review of all primary r...

Software testing involves identifying the test cases which discover errors in the program. However, exhaustive testing of software is very time consuming. In this paper, a technique is proposed to prioritize test case scenarios by identifying the critical path clusters using genetic algorithm. The test case scenarios are derived from the UML activity diagram and state chart diagram. The testing...

Separation of a racemic mixture of ibuprofen at a low concentration level by supercritical fluid chromatography in a simulated moving bed (SFC-SMB) is investigated by simulation. The feasibility of ibuprofen enantiomers separation has been experimentally examined in the literature. Our simulation results show that separation of ibuprofen enantiomers is feasible by this method, and R-ibuprofen a...

Most distributed real-time embedded systems are specified combining state diagram and data flow languages. This leads to several real-time codes which together do not necessarily satisfy the global specification, and consequently increases the development cycle because more tests are needed. Then, we propose, in order to obtain a single real-time code, to translate state diagram specification i...

This paper proposes new analysis method, called POAM (Problem-Oriented Analysis Method). POAM has been developed to solve several shortcomings of existing conceptual models (solution orientation and dependence of concrete development approaches). Those shortcomings have adverse effects on software development, since practitioners are encouraged to think in terms of a solution before the problem...
