13. Fatores associados à infecção do dengue no município de Belo Horizonte: estado de Minas Gerais, Brasil: características individuais e diferenças intra-urbanas
Dengue is the arbovirose with higher occurrence in the South Amaerica, Central America, Asian Southwest and Occidental Pacific urban centers. In the American continent the Aedes aegypti mosquito is responsible by the transmission of the dengue virus. Introduced in 1996 the disease became one of the major urban health problems in the City of Belo Horizonte, M

14. REFINERY SCHEDULING OPTIMIZATION USING GENETIC ALGORITHMS AND COOPERATIVE COEVOLUTION / OTIMIZAÇÃO DA PROGRAMAÇÃO DA PRODUÇÃO EM REFINARIAS DE PETRÓLEO UTILIZANDO ALGORITMOS GENÉTICOS E CO-EVOLUÇÃO COOPERATIVA
This work investigates the use of Genetic Algorithms and Cooperative Coevolution in refinery scheduling optimization. Oil refineries are one of the most important examples of multiproduct continuous plants, that is, a continuous processing system that generates a number of products simultaneously. A refinery processes various crude oil types and produces a w

15. A HYBRID IMPROVEMENT HEURISTICS FOR THE BIN PACKING PROBLEM AND ITS APPLICATION TO THE PROBLEM OF TASK SCHEDULING / UMA HEURÍSTICA HÍBRIDA DE MELHORIA PARA O PROBLEMA DE BIN PACKING E SUA APLICAÇÃO AO PROBLEMA DE ESCALONAMENTO DE TAREFAS
We propose in this work a hybrid improvement procedure for the bin packing problem. This heuristic has several components: lower and upper bounds; reductions, construction of initial solutions by reference to the dual problem;heuristics for load redistribution based on dominance, differencing, and unbalancing; and tabu search. We also investigate the applica

16. Algoritmos memeticos aplicados aos problemas de sequenciamento em maquinas
The Single Machine Scheduling Problem (SMS) is one of the most representative in the scheduling area. In this work we initially explore the SMS problem with time constraints (due-dates and setup times). The goal is to minimize the total tardiness, which is characterized by the sum of the delays in the production of all products. The method chosen is based on

17. Modelagem de um sistema kanban atraves de programação estocastica e metodos de resolução
The kanban production system is a pull-type system for shop floor control. It is based on the concept of Just-in-Time production and has the porpuse of scheduling production, reducing inventory levels to a minimum. In this work, a multi-stage assembly-structure production setting with capacity constraints for the component items and the final item is conside

18. Programação em maquinas paralelas não-relacionadas, sujeitas a divisão de tarefas
In this thesis new methods and procedures to solve the multimachine scheduling problem with early and tardy costs are proposed. The machines are unrelated, job splitting is allowed, the jobs may have different due dates and the changeover time to process a new job on a machine depends on the job previously processed on the same machine. This problem is new,

19. Times assincronos para o job shop scheduling problem : heuristica de construção
Asynchronous Teams (or A-Teams) are a new problem resolution technique that has been succesfully applied to Combinatorial Optimization problems. This technique uses several heurisJic algorithms that cooperate simultaneously with each other and find solutions that would not be found through isolated algorithms. The objective of this work is to verify the suit

20. Escalonamento dinamico de tarefas periodicas e esporadicas
Nowadays, the design and implementation of Hard Real-Time(HRT) Systems can only be accomplished through a formal methodological approach. These HRT systems are based upon the fact that the quantitative temporal behaviour must be meto Otherwise, severe negative consequences may occur and be spread in the environment. Such behaviour is due to the fact that HRT

21. Impact of administrative technology on acute care bed need.
This article reports an evaluation of the impact of three administrative technologies--Admission Scheduling (AS) Systems, Outpatient Surgery (OPS) Programs, and Preadmission Testing (PAT) Programs--on the number of acute care beds required by a hospital. The evaluation mechanism reported here is called the ADTECH Computerized Planning Model. ADTECH uses para

22. How Physicians Can Help Their Patients Quit Smoking: A Practical Guide
We describe practical, effective, office-based methods for physicians to use to assist patients to stop smoking that do not require special training or support personnel. Brief counseling achieves smoking cessation in a small percent of well patients but is more effective in patients with smoking-related illnesses or abnormal laboratory test results. Routine

23. Dual start motif in two lambdoid S genes unrelated to lambda S.
The lysis gene region of phage 21 contains three overlapping reading frames, designated S21, R21, and Rz21 on the basis of the analogy with the SRRz gene cluster of phage lambda. The 71-codon S21 gene complements lambda Sam7 for lysis function but shows no detectable homology with S lambda in the amino acid or nucleotide sequence. A highly related DNA sequen
