1. Impactos econômicos da ampliação do uso de energia solar residencial em Minas Gerais
Resumo Este artigo analisa os impactos econômicos de uma ampliação do uso de energia solar pelas famílias mineiras através do modelo de Equilíbrio Geral Computável (EGC) denominado Imagem-MG. Em contraste com outros trabalhos que utilizam essa metodologia para analisar questões energéticas, o presente trabalho se propôs a analisar os impactos distr

2. UNCERTAINTY, FLEXIBILITY AND OPERATIONAL PERFORMANCE OF COMPANIES: MODELLING FROM THE PERSPECTIVE OF MANAGERS
ABSTRACT Purpose: The purpose of this study is to propose a model to estimate how uncertainty, flexibility, and operational performance are related. The assumption is that competition in the current business environment has been broadening consumers’ options. These options have brought uncertainty to companies regarding the adoption of operational strateg

3. Structural and Mechanical Properties of Zr-Si-N Thin Films Prepared by Reactive Magnetron Sputtering
Zirconium silicon nitride (ZrSiN) thin films were deposited by reactive magnetron sputtering in order to verify the silicon influence on coating morphology and mechanical properties. The Si/(Zr+Si) ratio was adjusted between 0 to 15% just modifying the power applied on the silicon target. Only peaks associated to ZrN crystalline structure were observed in XR

4. RANKING OF WEB PAGES BY LEARNING MULTIPLE LATENT CATEGORIES / CLASSIFICAÇÃO DE PÁGINAS WEB POR APRENDIZAGEM DE MÚLTIPLAS CATEGORIAS LATENTES
The rapid growth and generalized accessibility of the World Wide Web (WWW) have led to an increase in research in the field of the information retrieval for Web pages. The WWW is an immense and prodigious environment in which Web pages resemble a huge community of elements. These elements are connected via hyperlinks on the basis of similarity between the co

5. Single event transients in logic circuits - load and propagation induced pulse broadening
The generation and propagation of single event transients (SET) in logic gate chains is studied and modeled. Regarding SET generation, we investigate the dependence of the generated SET pulse width on the struck node capacitance. Rising node capacitance may lead to amplified pulse width, indicating that increasing load capacitance alone is not an option for

6. Modelagem e caracterização da propagação de pulsos transientes causados por radiação ionizante / Modeling and characterization of the propagation of transient pulses caused by ionizing radiation
A propagação de eventos transientes na lógica combinacional é estudada através da simulação elétrica do circuito, utilizando-se o simulador Hspice. Uma das fontes de falhas transientes é o pulso transiente causado por partículas ionizantes que atingem o circuito. O estudo é centrado nas propriedades de mascaramento elétrico das portas lógicas. E

8. Teacher education and school violence / Formação de professores e violência nas escolas
This paper portrays an intervention research, the focus of which was school violence and teacher education. Such research is justifiable due to the manifestation of school violence, complaints coming from teachers about the lack of qualification to deal with the phenomenon, and their request to become qualified so they are able to face said problem at school

9. Desenvolvimento como acesso às políticas públicas: a reforma do estado e a concretização dos direitos prestacionais
The states evolution, after its liberal and the social stages, arrives at the post-social state, also regarded as regulatory state, which, in order to accomplish the states aims, employs indirect interventions in the economy. The new model of administration adapts principles and concepts form the private sector such as the quest for efficience and tangible r

10. ENTRE O POLÍTICO E O TÉCNICO, REFORMA ADMINISTRATIVA, ESFERA PÚBLICA E EDUCAÇÃO: um estudo sobre a experiência recente de Juiz de Fora - MG
This study analyses the administrative reform implemented by the city of Juiz de Fora (state of Minas Gerais, Brazil) between 2000 and 2004, and the effects this reform had upon the social sphere of the city, specially the managerial changes that took place in the education field. Our general aim is to analyze the relationship between the processes of admini

11. Hydrogenated Ge nanocrystals: band gap evolution with increasing size
The electronic band structure of various Ge quantum wires of different sizes, with hydrogenated surfaces, is studied using a nearest-neighbor empirical tight-binding Hamiltonian by means of a sp³s* atomic orbitals basis set. We suppose that the nanostructures have the same lattice structure and the same interatomic distance as in bulk Ge and that all the da
