1. Evaluation of OFDM Channel Sounding Techniques with Three Modulation Sequences
Abstract This paper presents an evaluation of multicarrier channel sounding techniques using different random and pseudo-random sequences to modulate the OFDM sounding signal. The Random (Rand), Pseudo-Noise (PN) and Zadoff-Chu (ZC) were tested, both in laboratory simulations and in field measurements. For the laboratory simulations Matlab routines were used

2. Characterization of polyurethan skin agglomerates for acoustic insulation from impact noise
Polymeric materials are greatly used in industry due to their versatility in application generating therefore, large quantities of solid waste. Population growth in urban areas, with living quarters mainly in residential buildings, face discomfort caused by noise, particularly by impact noise. Aiming at reducing the amount of polymeric material disposed of i

3. Noise-Induced Hearing Loss (NIHL): literature review with a focus on occupational medicine
According to the Ministry of Health (2006), Noise-Induced Hearing Loss (NIHL) is hearing loss caused by prolonged exposure to noise. It is characterized as sensorineural hearing loss and is usually bilateral, irreversible, and progressive while the exposure to noise continues. A NIHL is a predictable and preventable disease with an epidemiologically relevant

4. Avaliação de impactos da cadeia produtiva em aeroportos : o caso de Congonhas
Over time, the business grossed airport beyond its traditional functions, such as transporting passengers and cargo, commercial functions, with the inclusion of shopping malls, cinemas, food courts, among others. Thus, several developments aids such as logistics companies, car rental, travel agencies and even residential neighborhoods, occupied in a disorder

5. Avaliação qualitativa da paisagem sonora de parques urbanos. Estudo de caso : Parque Villa Lobos, em São Paulo / Qualitative assessment of soundscapes of Urban Parks case study : Villa Lobos Park, in São Paulo
An evaluation of sound environment of the Villa Lobos Park, in São Paulo, is presented in this paper taking into account the context and human perception. This work includes classic quantitative maps, with noise levels in decibels, and a qualitative assessment of the Soundscape (the sound environment, in a context, perceived by human beings). It also presen

6. Da rodovia da morte ao desvio pela vida: os conflitos socioambientais em torno da duplicação da BR-101 em Araranguá/SC (1995-2011) / From the highway to the deviation of the dead for life: conflicts around the duplication of the BR-101 in Araranguá / SC (1995 2011
The BR-101 in Araranguá is so related to the life of the city which is hardly mentioned in history books and research the city. Therefore, this research based in the History of the Present Time to delve into a subject comes to innovative local historiography. After years of development driven by agriculture and small industries organized themselves in refin

7. 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

9. Proposta metodológica para elaboração de mapas de ruído em ambiente SIG, segundo norma ISO 9613-2
Noise mapping is a new activity with growing awareness among public officials and communities. This work presents a methodological proposal for the generation of noise maps in a Geographic Information System (GIS), based on ISO 9613-2, which standards the calculus for noise attenuation during propagation outdoors. Besides the definitions of methodological pr

11. Arquitetura como interface para a informação: sobre a espacialização das tecnologias da informação rumo a práticas colaborativas
This study examines an intersection between the spatialization of information and CSCW - Computer Supported Collaborative Work. More specifically it is argued the possibility of influence of the spatial distribution of ICT (information and communication technologies) on the interactions between members of two remotely connected laboratories. Spatialization (

12. RUÍDO EM SANTA MARIA - RS A CONTRIBUIÇÃO DO TRÁFEGO VEICULAR EM ÁREA MISTA (Residencial/ Comercial)
The urban noise generated by traffic is shown as being one of the strong means of environmental pollution. It is known that its influence on the people facilitates unhealthy damages. This work tries to contribute with that theme, through measure of urban noise levels in road with great flow characterized as mixed area (commercial / residential) in Santa Mari
