1. Analysis of a car door subjected to side pole impact
Abstract The results of a study on the response of a side impact beam located in a car door to impact loading is presented. The side impact beam is situated in both the front and rear side doors of a vehicle between the inner and outer shells to minimise intrusion into the passenger compartment during a collision whilst absorbing as much impact energy as pos

2. A Prediction Model for Night Recovery of Embarked Aircrafts Based on System Dynamics
ABSTRACT: In order to make a sensible prediction on the air traffic flow management with conditions of wave-off and bolter, a system dynamic model for the night recovery operations of embarked aircrafts is built to ensure the adaption of air traffic flow with the capacity of air control at each phase of the recovery operations. The model aims at the characte

3. Simulating a Multi-Vehicle Traffic Sensing System Based on Radio Tomographic Imaging
Abstract One of the most recently developed wireless technologies is Radio Tomographic Imaging (RTI). RTI employs a wireless sensor network that produces images of the change in the electromagnetic field of a monitored area using Received Signal Strength (RSS) measurements. This allows the tracking of device-free objects such as humans and cars. This paper i

4. A Performance Evaluation of WLAN-Femtocell-LTE beyond the Capacity Crunch. Does Femtocell have to overcome WLAN or can they coexist in HetNets?
Abstract This paper originates from a practical experiment based on Mesh Networks. The promising results obtained from this experiment prompted us to discuss in greater depth whether Wireless Local Area Networks (WLAN) are still useful for current communications. This means that on the one hand femtocells can be defined as small base stations that use the sa

5. Simulation model of discret events applied to the planning and operation of a toll plaza
AbstractThis work investigates the congestion and traffic flow in a tool plaza, and proposes a methodology for the classification of highway flows and its service levels based on a combination of the Highway Capacity Manual – HCM and Discrete Events Simulation fundaments. The proposed mesoscopic simulation is used to analyze service levels of different phy

6. DECISION WITH ARTIFICIAL NEURAL NETWORKS IN DISCRETE EVENT SIMULATION MODELS ON A TRAFFIC SYSTEM
ABSTRACT This work aims to demonstrate the use of a mechanism to be applied in the development of the discrete-event simulation models that perform decision operations through the implementation of an artificial neural network. Actions that involve complex operations performed by a human agent in a process, for example, are often modeled in simplified form w

7. Micro-simulation based evaluation of Queue Jump Lane at isolated urban intersections: an experience in Kolkata
Abstract Poor service quality is one of the major causes for declining share of buses in urban India. Improvement of bus travel time by implementing bus priority measures at intersections is well regarded as an effective instrument to improve bus service by reducing the travel time. However, only a few research works have been reported in the literature on b

8. A path-following driver/vehicle model with optimized lateral dynamic controller
Reduction in traffic congestion and overall number of accidents, especially within the last decade, can be attributed to the enormous progress in active safety. Vehicle path following control with the presence of driver commands can be regarded as one of the important issues in vehicle active safety systems development and more realistic explanation of vehic

9. Algoritmo de escalonamento DRR com quantum adaptativo para o tráfego downlink de redes IEEE 802.16j / DRR adaptive quantum scheduling algorithm for downlink traffic of IEEE 802.16j networks
IEEE 802.16j networks provide, through the Relay Station (RS), improvements with regard to previous specifications of WiMAX in terms of increased coverage area, reduction of deployment costs due to low cost of RS compared to a Base Station (BS) and system average throughput increase. Its main purpose is to meet demands for wireless broadband access at lower

10. Uma abordagem baseada em agentes para avaliação do balanceamento de carga em redes veiculares : dois estudos de caso
O fenômeno do congestionamento, decorrente do rápido aumento da demanda por todos os meios de transporte só tende a se agravar, já que sistemas de transporte (vistos como um todo) têm um grande impacto na economia mundial. No caso do transporte veicular em particular, é notório que a demanda por mobilidade é uma das características da nossa sociedad

11. Simulação e emulação de tráfego multimídia em redes IP / Simulation and emulation of multimedia traffic over IP network
Esta dissertação apresenta dois estudos, o primeiro trata de uma substituição do socket pela pilha TCP/IP uIP de um gerador de trafego multimídia sobre IP com o objetivo de manipularmos os campos dos cabeçalhos IP (Ipv4 Type of Service, e Ipv6 Traffic Class), que serão utilizados para a identificação dos serviços multimídia. O gerador gera diferen

12. Análise de desempenho no uso de pré-busca para distribuição de vídeo sobre redes P2P
Peer-to-Peer Video on Demand Systems have well stabilished its importance in recent years. Such consolidation is due to the high gains that may be archieved in terms savings in transmission bandwidth of the servers. In this work, we evaluate how this technology can enhance the gains for the transmission of continuous media over the Internet. To achieve this
