A QUALITY MANAGEMENT SYSTEM FOR POSITIONING WITH GNSS TECHNOLOGY

This paper presents a proposal for a Quality Management System for a generic GNSS Surveying Company as an alternative for management and service quality improvements. As a result of the increased demand for GNSS measurements, a large number of new or restructured companies were established to operate in that market. Considering that GNSS surveying is a new process, some changes must be performed in order to accommodate the old surveying techniques and the old fashioned management to the new reality. This requires a new management model that must be based on a well-described procedure sequence aiming at the Total Management Quality for the company. The proposed Quality Management System was based on the requirements of the Quality System ISO 9000:2000, applied to the whole company, focusing on the productive process of GNSS surveying work.

Constraints on four-fermion contact interactions from precise electroweak measurements

We establish constraints on a general four-fermion contact interaction from precise measurements of electroweak parameters. We compute the one-loop contribution for the leptonic Z width, anomalous magnetic, weak-magnetic, electric and weak dipole moments of leptons in order to extract bounds on the energy scale of these effective interactions.

Precise Measurement of the Top-Quark Mass from lepton plus jets Events

We measure the mass of the top quark using top-quark pair candidate events in the lepton+jets channel from data corresponding to 1 fb(-1) of integrated luminosity collected by the D0 experiment at the Fermilab Tevatron collider. We use a likelihood technique that reduces the jet energy scale uncertainty by combining an in situ jet energy calibration with the independent constraint on the jet energy scale (JES) from the calibration derived using photon+jets and dijet samples. We find the mass of the top quark to be 171.5 +/- 1.8(stat.+JES)+/- 1.1(syst.) GeV.

Determinação altimétrica através do sistema de posicionamento global

Este estudo tem por objetivo verificar a influência do tempo de coleta de dados com receptores GPS nas determinações altimétricas. O levantamento altimétrico é realizado através do método de posicionamento relativo estático, utilizando dois receptores GPS de uma freqüência, em diferentes tempos de ocupação (30, 15, 10 e 5 minutos) com uma taxa de gravação de dois segundos. As altitudes obtidas com receptores GPS são comparadas com as altitudes determinadas por nivelamento trigonométrico com Estação Total. Os resultados mostraram que os tempos de ocupação menores que 30 minutos (15, 10 e 5 minutos) também são adequados para a obtenção de diferenças centimétricas nas altitudes analisadas. Mesmo considerando a precisão dos métodos topográficos convencionais, este estudo demonstra a possibilidade da utilização do Sistema de Posicionamento Global (GPS) de forma precisa nos levantamentos altimétricos, desde que se efetue a modelagem da ondulação geoidal.
