49. Representações Sociais da Violência e as Incivilidades no Contexto da Violência no Município e Escolas de Goiânia
One of psychosocial factors determining the sense of insecurity are called the incivility that is a central theme in understanding the phenomenon of urban violence, once that occurs by living in harmony breaks that signal a break with social norms and values. Formed as the "enemy" of citizenship, especially with regard to community ties housing, incivilities

50. Influência da condutividade e permissividade do solo em função da frequência no cálculo da impedância longitudinal e admitância transversal de linhas aéreas de transmissão / Influence of earth´s conductivity and permittivity frequency dependence on longitudinal impedance and transversal admittance transmission line´s parameters calculation
This thesis aims to propose more accurate models for calculating the electrical parameters of overhead power transmission lines. The influence of earth s conductivity and permittivity frequency dependence is evaluated when calculating transversal and longitudinal transmission lines parameters in the frequency range 0 to 2 MHz. This frequency range covers the

51. Iterative feedback tuning of uncertain state space systems
Iterative Feedback Tuning is a purely data driven tuning algorithm for optimizing control parameters based on closed loop data. The algorithm is designed to produce an unbiased estimate of the performance cost function gradient for iteratively improving the control parameters to achieve optimal loop performance. This tuning method has been developed for syst

52. Sistemas de organização do conhecimento : uma reflexão no contexto da ciência da informação
This research studies the knowledge organization systems (KOS) related to theories to build thesaurus, taxonomies, ontologies and classification systems in the literature field of Information Science. It uses the methodology of literature review and a research on the same field databases in order to investigate the bibliographic production about the theme, f

53. Workflow modelling using a temporal object-oriented model with roles
The representation of all the processes that compose a workflow, including all the constituent activities, their execution sequence and relationships, the agents responsible for their execution, and the resources that are used during execution, is known as Workflow Modelling. Several techniques are being proposed to model workflow. In this paper a workflow m

56. Inclusão educacional de crianças com deficiência no município de João Pessoa: as representações sociais das mães (1996-2006)
The implementation of the inclusive education has been the target of the debates, nationals and internationals conferences themes, and the critics and praises target by specialists, parents and teachers, the major actors involved on the process. The inclusion of kids with special educational needs in the regular education system gets inside in the context of

57. Padres, beatas e devotos : figuras do anticlericalismo na literatura naturalista brasileira
The present work makes an analysis of the forms of representation of religious figures in Brazilian literature. It has as its corpus three well known naturalists works The Mulatto (1881), by Aluísio Azevedo; The Man (1887), also written by Azevedo, and Morbus: pathologic novel (1898), by Faria Neves Sobrinho the main intention of these works was to examine

58. A proposal for optimized analysis of transient currents in conductive materials. / Uma proposta para análise otimizada de correntes transitórias em materiais condutores.
In this work, a methodology is developed, based on the application of the moment method associated to a finite difference approximation, for time domain analysis of transient current distribution in conducting media. The computational procedure allows that long conductors with any cross section can be considered, approximated by filamentary elements. Thus, t

59. Localização de faltas em linhas de transmissão de múltiplos terminais a partir de registros oscilográficos sincronizados via transformada wavelet
The electric energy is essential to the development of modern society and its increasing demand in recent years, effect from population and economic growth, becomes the companies more interested in the quality and continuity of supply, factors regulated by ANEEL (Agência Nacional de Energia Elétrica). These factors must be attended when a permanent fault o
