In this work it was developed mathematical resolutions taking as parameter maximum intensity values for the interference analysis of electric and magnetic fields and was given two virtual computer system that supports families of CDMA and WCDMA technologies. The first family were developed computational resources to solve electric and magnetic field calculations and power densities in Radio Base stations , with the use of CDMA technology in the 800 MHz band , taking into account the permissible values referenced by the Commission International Protection on non-Ionizing Radiation . The first family is divided into two segments of calculation carried out in virtual operation. In the first segment to compute the interference field radiated by the base station with input information such as radio channel power; Gain antenna; Radio channel number; Operating frequency; Losses in the cable; Attenuation of direction; Minimum Distance; Reflections. Said computing system allows to quickly and without the need of implementing instruments for measurements, meet the following calculated values: Effective Radiated Power; Sector Power Density; Electric field in the sector; Magnetic field in the sector; Magnetic flux density; point of maximum permissible exposure of electric field and power density. The results are shown in charts for clarity of view of power density in the industry, as well as the coverage area definition. The computer module also includes folders specifications antennas, cables and towers used in cellular telephony, the following manufacturers: RFS World, Andrew, Karthein and BRASILSAT. Many are presented "links" network access "Internet" to supplement the cable specifications, antennas, etc. . In the second segment of the first family work with more variables , seeking to perform calculations quickly and safely assisting in obtaining results of radio signal loss produced by ERB . This module displays screens representing propagation systems denominated "A" and "B". By propagating "A" are obtained radio signal attenuation calculations in areas of urban models , dense urban , suburban , and rural open . In reflection calculations are present the reflection coefficients , the standing wave ratio , return loss , the reflected power ratio , as well as the loss of the signal by mismatch impedance. With the spread " B" seek radio signal losses in the survey line and not targeted , the effective area , the power density , the received power , the coverage radius , the conversion levels and the gain conversion systems radiant . The second family of virtual computing system consists of 7 modules of which 5 are geared towards the design of WCDMA and 2 technology for calculation of telephone traffic serving CDMA and WCDMA . It includes a portfolio of radiant systems used on the site. In the virtual operation of the module 1 is compute-: distance frequency reuse, channel capacity with noise and without noise, Doppler frequency, modulation rate and channel efficiency; Module 2 includes computes the cell area, thermal noise, noise power (dB), noise figure, signal to noise ratio, bit of power (dBm); with the module 3 reaches the calculation: breakpoint, processing gain (dB) loss in the space of BTS, noise power (w), chip period and frequency reuse factor. Module 4 scales effective radiated power, sectorization gain, voice activity and load effect. The module 5 performs the calculation processing gain (Hz / bps) bit time, bit energy (Ws). Module 6 deals with the telephone traffic and scales 1: traffic volume, occupancy intensity, average time of occupancy, traffic intensity, calls completed, congestion. Module 7 deals with two telephone traffic and allows calculating call completion and not completed in HMM. Tests were performed on the mobile network performance field for the calculation of data relating to: CINP , CPI , RSRP , RSRQ , EARFCN , Drop Call , Block Call , Pilot , Data Bler , RSCP , Short Call, Long Call and Data Call ; ECIO - Short Call and Long Call , Data Call Troughput . As survey were conducted surveys of electric and magnetic field in an ERB , trying to observe the degree of exposure to non-ionizing radiation they are exposed to the general public and occupational element. The results were compared to permissible values for health endorsed by the ICNIRP and the CENELEC .

Através do processamento de dados sísmicos convertem-se registos de campo em secções sísmicas com significado geológico, que revelam informações e ajudam a delinear as camadas geológicas do subsolo e identificar estruturas soterradas. Portanto, a interpretação dos dados sísmicos só é boa se o processamento também o for. Este trabalho é resultado de um estágio curricular na empresa de prospecção geofísica GeoSurveys, que consistiu principalmente em processar 18 linhas de dados de sísmica de reflexão multicanal de alta resolução adquiridas na ilha de Pulau Tekong em Singapura, que têm como finalidade investigação do solo da baia desta mesma ilha. Estes dados foram cedidos à GeoSurveys para fins académicos, caso em que se inclui esta dissertação. Para atingir os objectivos propostos que consistiam em avaliar o impacto das condições de operação na qualidade do sinal sísmico e interpretação das linhas, fez-se o processamento das linhas utilizando um fluxo processamento padrão utilizado na empresa, com recurso ao software Radex Pro. Este fluxo de processamento tem como mais-valia o método de correcções estáticas, o UHRS trim statics, além das técnicas habituais utilizadas para melhorar a resolução das secções sísmicas como é o caso da desconvolução, a atenuação de ruído através do stacking, correcções de NMO, e migração, entre outras técnicas. A interpretação das linhas sísmicas processadas foi feita no software Kingdom Suite (IHS), através da distinção da configuração interna dos reflectores em cada secção sísmica, estabelecendo deste modo as principais unidades sismo-estratigráficas e identificando as zonas de interface que delimitam os horizontes principais. Foi feito ainda um estudo geológico sumário da área de pesquisa e da evolução geodinâmica da região.
