13. PEHS: ARQUITETURA DE UM SISTEMA ELETRÔNICO DE SAÚDE PERVASIVO ORIENTADO ÀS ATIVIDADES DO USUÁRIO CLÍNICO
In despite of the great advantages of adopting computer systems for storing patient s information in hospitals and clinics, such systems are adopted with restrictions in these institutions. Some studies indicate that the rejection of such systems by the clinicians is greats due to computing not consider the particularities of the activities performed by the

14. Simulador eletromagnético em um ambiente de grades computacionais / Eletromagnetic simulator in a grid computing environment
The aim of this work is to develop the Pre and Post-Processing stages from an electromagnetic simulation suite, called SSAR-BR, and also a grid computational environment, which permits the execution of large electromagnetic problems. The processing stage, based in the Finite Difference Time Domain (FDTD) method, has been already developed as part of a doctor

15. Decision support system development for growth, nutrition, and sexual maturation analysis for primary care use. / Desenvolvimento de um programa de apoio à decisão para análise do crescimento, nutrição e maturação sexual para uso na atenção primária
The main drive to develop a Health Decision Support System (HDSS) lies on creating a digital system to help medical practitioners exposed to an ever increasing quantity of data, information and knowledge which they have to resort to in order to conduct their duties properly. In a practice field such as adolescent healthcare, in which physicians diagnose devi

16. Sistema especialista fuzzy para dimensionamento de bombeio mecânico
Despite the emergence of other forms of artificial lift, sucker rod pumping systems remains hegemonic because of its flexibility of operation and lower investment cost compared to other lifting techniques developed. A successful rod pumping sizing necessarily passes through the supply of estimated flow and the controlled wear of pumping equipment used in the

17. WARPING-BASED METHODOLOGY TO CORRECT DISTORTION IN ENDOSCOPY SYSTEMS / METODOLOGIA BASEADA EM WARPING PARA CORREÇÃO DE DISTORÇÕES EM SISTEMAS DE ENDOSCOPIA
Images captured in endoscopy examinations show some distortion, the radial is the most visible. The radial distortion appears in images due to lens used in endoscopes. When a doctor or researcher is analyzing a distorted image, he can not see the exact size of an organ, tumor or lesion, due the magnification in the center of the image and a contraction in th

19. Extração de preferências por meio de avaliações de comportamentos observados. / Preference elicitation using evaluation over observed behaviours.
Recently, computer systems have been delegated to accomplish a variety of tasks, when the computer system can be more reliable or when the task is not suitable or not recommended for a human being. The use of preference elicitation in computational systems helps to improve such delegation, enabling lay people to program easily a computer system with their ow

20. Development and evaluation of a head controlled human-computer interface with mouse functions for physically disabled users / Desenvolvimento e avaliação de uma interface homem-computador, com as funções de um "mouse", controlada pelo movimento da cabeça para uso em pessoas com deficiências físicas
The objectives of this study were to develop a head controlled pointer device with mouse functions and compare its performance when operated in absolute versus relative (joystick like) modes by ten quadriplegic subjects and ten people without neuromuscular impairment. The device was composed of a video camera, a computer program and a reflective paper target

21. Programa computacional (PROIRRIGA) para avaliaÃÃo da uniformidade em irrigaÃÃo por gotejamento e sua validaÃÃo
The uniformity in trickle irrigation systems is affected by factors hydraulic, air, lack of maintenance and poor quality of irrigation water resulting in poor distribution of water, either excessive or insufficient, causing loss of productivity. Considering the increased use of automated drip irrigation on farms based on the Family Farm, this work establishe

23. FAVIHC Framework de Avaliação da Interação Humano-Computador / FAVIHC - Framework de AValiação da Interação Humano Computador
In order to implement a software development process following certain quality constraints, which must be observed by the involved professionals (namely developers, customers, users and designers), it is paramount that those professionals interact. Such an interaction is necessary in order to design, build and evaluate the software. Moreover, the evaluation

24. A QoS-Based approach for dynamic web service composition.
Web services have become a de facto standard for integration of systems in distributed environments by providing means for exchanging data in a standardized way over the Internet. In fact, this allows computer-computer interaction regardless the programming languages, platform and operating systems used. However, the way services are defined is not enough fo
