2. 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

3. Robust evaluation of time since awakening using force platform posturography
INTRODUCTION: Sleepiness is responsible for a considerable proportion of traffic accidents. It is thus an important traffic safety issue to find a robust, objective and practical way to estimate the amount of time a person has been awake. To attempt to meet this goal, we investigated the relationship between sleepiness and posture control. METHODS: Subjects

4. AVALIAÇÃO DO RUÍDO DE TRÁFEGO VEICULAR EM ÁREA CENTRAL DE CHAPECÓ SC / EVALUATION OF VEHICULAR TRAFFIC NOISE IN CENTRAL ZONE CHAPECÓ SC
The development of cities and population growth have led, among other urban problems, the increase in sound pressure levels of environmental noise. With the overcrowding of cities, the roads start to host large flows of vehicles, among other sound sources. These factors, coupled with the layout and massing of buildings, make the road a polluter responsible f

5. Estimação de velocidade de composições usando processamento de vídeo / Speed estimation.of trains using vídeo processing
This dissertation aims to study a method of estimating the speed of railway vehicles using video processing. The proposed system uses cameras disposed alongside railways to monitor traffic as well as estimate train speeds. Such a system would allow the machinist to have a backup control system, regardless of the control systems already used by the operator o

6. Medição do aporte atmosférico dos elementos-traço nos municípios de Campinas e Paulínia com auxílio da espécie vegetal Tillanásia usneoides (L.) / Measurement of atmospheric supply of trace elements in Campinas and Paulínia with support of vegetal specie Tillandsia usneoides (L.)
The epiphytic bromeliad Tillandsia usneoides (L.) was used as biomonitor of the atmosphere at seven sites along a transect of the municipalities of Campinas and Paulinia. The selected sites are located near highways, industries and avenues, as well as in places farther away from human activities. The samples of were introduced by about two months during five

7. Identificação dos parâmetros necessários para análise de rede de estrutura múltipla com base na análise por simulação de fluxo TCP por vazão de fluidos
The major worldwide operators of transport in telecommunication networks have sought tools that, together with traffic statistics, allow their infrastructure to be enabled such that there is no rejection or delay of traffic due to transport capacity. Observing a private network with a considerable geographic size and, for a private high-density network with

8. IEC-61850: interoperability and interchangeability between supervision, control and protection equipment using data communication networks / IEC-61850: interoperabilidade e intercambialidade entre equipamentos de supervisão, controle e proteção através das redes de comunicação de dados
Data communication has always been considered as a critical factor in real time operation of electric power systems. This is due to the need for fast and accurate decisions at different locations, from power generation to the user interfaces. With the digital technology, measurement, signals and commands are encrypted into data packets that travels on the su
