Genetic Algorithms for the bus driver scheduling problem : a case study
T. G. Dias; J. P. de Sousa; J. F. CunhaThis paper describes an application of genetic algorithms to the bus driver scheduling problem. The application of genetic algorithms extends the traditional approach of Set Covering / Set Partitioning formulations, allowing the simultaneous consideration of several complex criteria. The genetic algorithm is integrated in a DSS but it can be used as very interactive tool or a stand-alone application. It incorpo...
Nephrotic syndrome. What is new since the 1988 study?.
Seves, M G; Serviço 2, Unidade de Nefrologia, Hospital de Dona Estefânia, Lisboa.; Brito, M J; Lamy, S; Luiz, P V; Bastos, G; Faleiro, M; Batista, JThe authors make a retrospective review of 53 new cases of Nephrotic Syndrome followed up in the Nephrology Unit from November 1988 to March 1994, bearing in mind the evaluation of casual changes of the disease standard regarding a previous study of 1988. Epidemiological, clinical, therapeutical and evolutional aspects were studied. Forty-four cases of primary Nephrotic Syndrome (83%) were identified, 61.4% of ...
Renal dysplasia: clinico-pathologic review.
Cunha, A S; Laboratório de Anatomia Patológica, Escola Superior de Medicina Dentária de Lisboa, Hospital de D. Estefânia.; de Sousa, J F; Garcia, CHistology records from 63 nephrectomies were reviewed; 22 patients had unilateral totally dysplastic kidneys and 5 had polar or segmental dysplasia. A clinicopathological study of these cases was undertaken. In the first group, there was a slight male preponderance and 75% of the patients presented were under two years of age. Urinary tract infection was the most common complaint. 4 patients were diagnosed in u...
