13. Heurísticas e algoritmo exato para o problema de roteamento de veículos com coleta e entrega simultâneas
This work adresses the Vehicle Routing Problem with Simultaneous Pickup and Delivery, where routes must be devised to fulfil the pickup and delivery requests of a set of customers. Each customer must be served by only one route, the load it receives isbrought from a central depot, to where the picked-up load is also taken. The capacity of the used vehicles m

14. Image matching and classification for UAV navigation.
Unmanned aerial vehicles, known as UAVs, have evolved over the past two decades to sophisticated aircraft robots able to carry out surveillance, recognition, remote sensing and even attack missions. But there are not many alternatives of autonomous navigation systems for most of these aircraft which still require human intervention to navigate. Devices such

15. Mechanistic study of the synthesis of alquilfenilselenetos, the reaction type Zn-Barbier aqueous vehicle / Estudo mecanístico da síntese de alquilfenilselenetos, pela reação tipo Zn-Barbier em meio aquoso
Alkyl phenyl selenides are versatile synthetic intermediates. In addition to the traditional methods, a method of synthesis was developed by Bieber by reacting diphenyl diselenide with organic halides using zinc dust in water / acetonitrile for a wide range of substrates. The lack of precedents in the understanding of this reaction limits the choice of the c

16. Novos algoritmos para problemas dinâmicos de roteirização de veículos com janela de tempo
- A Dynamic Vehicle Routing Problem with Time Windows (PRVJTD) is a specialization of the Vehicle Routing Problem, which presents routes to deliver and/or collect merchandize, with penalties due to the delay or anticipation on arrival of vehicles and inclusion of new pick up places when a route is in course. This dissertation presents new algorithms to solve

18. Building preventive patrol routes / Construção de rotas para patrulhamento urbano preventivo
In this text we study one aspect of the urban community policing: routine patrol route planning. We seek routes that guarantee visibility, as this has a sizable impact on the community s perceived safety and allows for quick emergency responses, and that provide surveillance of public buildings (e.g., hospitals, schools). The planning is restricted to the av

19. Utilização de algoritmos genéticos híbridos e Web 2.0 no desenvolvimento de sistemas de roteirização de veículos
The use of a computer system for vehicle routing is essential for the competitiveness of companies working with distribution of resources and products. Despite high cost, such a system ofiers a guaranteed return on investment made. Using a Metaheuristics techniques combined with the resources currently ofiered by web, free development tools can be developed

20. Development of a new vaccine approach against hemolytic uremic syndrome using genetically modified Bacillus subtilis strain expressing Stx2 EHEC toxin. / Desenvolvimento de uma nova estratégia vacinal contra síndrome hemolítica urêmica utilizando linhagens geneticamente modificadas de Bacillus subtilis capazes de expressar a toxina Stx2 de EHEC.
The Hemolytic Uremic Syndrome (HUS) is the main disease associated with infections with Shiga toxin (Stx) - producing Escherichia coli strain and no effective vaccine or treatment exist. The Stx toxin consist of an enzymatically active A subunit and a pentameric B subunit responsible toxin binding to host cells. In this work we propose the use of Bacillus su

21. Algoritmos genéticos híbridos sem delimitadores de rotas para problemas de roteirização de veículos. / Hybrid genetic algorithms without trip delimeters for vehicle routing problems.
In the Vehicle Routing Problem (VRP) we seek for a set of minimum-cost vehicle routes for a fleet of identical vehicles, each starting and ending at a depot, such that each customer is visited exactly once and the total demand of any route does not exceed the vehicle capacity. Several families of heuristics have been proposed for the VRP. They can be broadly

22. The period vehicle routing problem. / O problema de roteirização periódica de veículos.
The period vehicle routing problem can be viewed as a generalization of the classic vehicle routing problem due to two singular features: a planning period longer than one day in which vehicles make several trips and frequencies of visit associated to points to be serviced. This type of problem may arise in different practical applications. Nowadays, some Br

23. Quantificação dos impactos econômicos e ambientais decorrentes do estado de conservação das rodovias brasileiras / Quantifying of the economic and environmental impacts deriving from Brazilians highways state of conservation
Due to importance of the road transportation for the Brazilian economy related to its participation in the matrix of load transport, to its high participation in the fossil fuels consumption (diesel) and in the CO2 emissions, this study evaluated if highways in better state of conservation imply in economic and environmental benefits. The economic benefits w

24. Monitoring charter bus service using global positioning system / Utilização do sistema de posicionamento global para monitoramento de transporte fretado
This research aims to point out the advantages and what still needs to be improved in an Automatic Vehicle Location - AVL - system applied to the charter bus service. The sample of three charter bus lines serving Campinas University (Unicamp) s workers on their way from home to office, in a seven weak period. The AVL equipment was used to collect electronic
