Planeamiento de la expansión de sistemas de transmisión considerando contingencias y demanda incierta

This paper presents a methodology and a mathematical model to solve the expansion planning problem that takes into account the effect of contingencies in the planning stage, and considers the demand as a stochastic variable within a specified range. In this way, it is possible to find a solution that minimizes the investment costs guarantying reliability and minimizing future load shedding. The mathematical model of the expansion planning can be represented by a mixed integer nonlinear programming problem. To solve this problem a specialized Genetic Algorithm combined with Linear Programming was implemented.

Simulação da oferta e demanda de recursos hídricos nas bacias dos rios piracicaba, capivarí e jundiaí: Uma análise em dinâmica de sistemas

A dynamic systems water resources simulation model was developed as a tool to help to analyze water resources management alternatives for the Piracicaba, Capivari and Jundiaí River Water Basins (BH-PCJ). Different politics policy were simulated for 40-year. The model estimates water supply and demand, as well as contamination load from several consumers. Six runs were performed using average precipitation value, changing water supply and demand, and different volumes diverted from BH-PCJ to BH-Alto Tietê For the Business as Usual, the Sustainability Index went from 0.41 in 2010 to 0.22 by 2050; the Water Use Index changed from 80.7% in 2010, to 125.5% by 2050; and the Falkenmark Index changed from 1,302 m 3 person -1 year -1 in 2010 to 774 m 3 P -1 year -1 by 2050. It was noticed that sanitation is one of the biggest concerns in the near future at PCJ River Basin.

Percepções de profissionais de uma organização de procura de órgãos sobre a entrevista com familiares de potenciais doadores

In the last twenty years, and more expressively in the past decade, the search for improvement in the organ transplantation system has contributed to the achievement of positive results in the Brazilian statistics related to the survival of transplanted individuals. However, for a transplantation to be performed, a number of phases must be followed by professionals working in organ search services. The phase that generates the greatest tension is undoubtedly that of family interviews, as it involves both the feelings of relatives who are facing a recent loss and those of interviewers who need to know how to deal with families at this time. The goal of this study was to apprehend perceptions of professionals working for an Organ Search Organization concerning interviews with relatives of potential donors. The qualitative methodology was used by adopting the Collective Subject Discourse for data organization. Interviews were conducted with six staff members of an organ search service whose experience as interviewers comprised from eight to fourteen years of work. It was possible to apprehend the professionals’ perceptions of family interviews and identify facilitating and hindering factors in this phase of the donation process. Such factors mainly involve: contact with the teams assisting patients, the difficult moment that families are experiencing and the teams’ as well as the institution’s preparation for rendering this type of service. The balance between the offer of and demand for organs in Brazil will only be achieved by means of an efficient and effective structure in transplantation organ search services and increased donation consent rates to be obtained by adequate communication between interviewers and relatives

Previsão da demanda doméstica da aviação comercial européia

This paper work has as objective the study and forecasting of the demand behavior for the European commercial aviation industry. Once economy and demand has a straight relationship, the tool chosen to perform this forecast was the Econometry. In order to get a more efficient forecast, a complete analysis of the environment in which the aviation sector is, to understand all factors with influence over the market as a whole. Only then, the variables which would be tested for the correlation with the demand were picked. The final results of this study has achieved all objectives set and has given a better view over the European Commercial Aviation Market
