This study aims to develop a microscopic pedestrian behavior model considering various interactions on pedestrian dynamics at crosswalks. Particularly, we take into account the evasion behavior with counter-flow pedestrians, the following behavior with leader pedestrians, and the collision avoidance behavior with vehicles. Aerial video data at one intersection in Beijing, China are extracted fo...

OBJECTIVE To determine whether community populations in community popular opinion leader intervention venues showed greater reductions in sexual risk practices and lower HIV/sexually transmitted disease (STD) incidence than those in comparison venues. METHODS A 5-country group-randomized trial, conducted from 2002 to 2007, enrolled cohorts from 20 to 40 venues in each country. Venues, matched...

Animals within groups need to coordinate their reactions to perceived environmental features and to each other in order to safely move from one point to another. This paper extends our previously published work on the flight patterns of Myotis velifer that have been observed in a habitat near Johnson City, Texas. Each evening, these bats emerge from a cave in sequences of small groups that typi...

In nano-based microarchitectural design, achieving higher clock frequency is confronted with thermal restrictions especially with the presense of temperature-variant leakage power. While a module temperature depends both on power density and the thermal coupling with the neighboring blocks, thermal-aware floorplans have been introduced to reduce peak temperature. The major drawback is that the ...

We address the enumeration and the leader election problems over partially anonymous and multi-hop broadcast networks. We consider an asynchronous communication model where each process broadcasts a message and all its neighbours receive this message after arbitrary and unpredictable time. In this paper, we present necessary conditions that must be satisfied by any graph to solve these problems...

In this paper we present and analyze a wireless wave leader election protocol (WWLE) for wireless mobile ad hoc sensor networks. We present also a mathematical model for the energy consumption within a sensor node. The capabilities of a node being a leader (like available resources such as battery energy, network capabilities, etc.) are integrated in the algorithm. The simulation results show t...

Traffic oscillation, stop and go traffic, is created by different reasons such as: sudden speed drop of leader vehicle. Stop and go traffic commonly is observed in congested freeways results in traffic oscillation. Many theories had been presented to define congestion traffic based on laws of physics such as: thermodynamics and fluid. But, these theories could not explain the complexity of driv...
