Sistema compacto de cogeração com motor de combustão interna

Sistema compacto de cogeração com motor de combustão interna compreendendo a interligação mecânica de um motor de combustão interna (M), operando com gasolina e ou gás, com um gerador de eletricidade (G), e um trocador de calor água/água (TC1), onde a troca de calor ocorre entre a água proveniente do conjunto de refrigeração do motor (M) e a água a ser aquecida proveniente da rede de abastecimento...

Evolução da dívida pública mobiliária interna e o gasto social da União nos anos de 2003 a 2010

This study presents the trajectory of domestic federal public debt from Brazil in the years 2003 to 2010. Scales the amount spent on financial burden to pay the debt in relation to what was spent on items related to social development, health, education and welfare. The study concludes that Brazil despite an increase in social spending, with effective results, expenditures for the cost of domestic federal debt were much higher than social spending. The numbers were expressive in the maintenance of debt and very tiny in relation to social spending

Desenvolvimento de experiências de acionamento e controle do movimento angular de motores de indução trifásico

This paper aims to show practical and effectiveexperiencesfor lessons Industrial Automation Laboratory taught inundergraduate degreein ElectricalEngineering from the University Júlio MesquitaFilho - UNESP, Guaratinguetá. Experiments carriedsimulatecontrol and drive systems of electric three phase induction motors (MIT)widely usedinindustries. The experiments simulate a manufacturing environment where there isa need to control the activation and continuous operation ofelectricmotors. Seven experimentsthat simulatethe firing of electrical motors through a controlsystem, a driver along with asimulator loads coupled to the electric motor was developed. Experiments usinga Programmable Logic Controller (PLC) as acontroller,an inverter frequencyasdriver, and MagneticBrake, as simulatorengine loads . The experiments were divided accordingto the speed reference signal used fordrivingand operating the electric motor: digital and analog. The first five experiments performing the drive control and operation of the electric motor via digital signals. The sixth and seventh experiments using an analog signal as a reference speed for the electric motor

Proteção de motores elétricos de grande porte

Large electric motors require greater care when driving, especially during continuous operation since they are part of day-to-day manufacturing sector, acting essentially to ensure that no damage occurs to the production process and equipment that are part of the same system. This work includes the analysis of electrical protection in a system comprised of a three phase induction motor driven by a frequency converter as well as an analysis of the functions of a multifunction electronic relay. It is presented a comparison between the existing functions in a converter and a relay and a real case is described in order to exemplify the use of an electric motor and features that are aimed at their protection, and the system in which it is inserted. Based on the results, it is of great importance in this field of performance studies, generating relevant results, which may be exposed in order to unify into a single document, different sources of information that are arranged randomly, improve utilization motor and extend the life of equipment forming part of the electrical installation

Comunicação interna e gestão de pessoas: um olhar para as relações humanas nas organizações

The main purpose of this study is to show how internal communication can be allied to people management in the process of transformation of the organizations. It is known that the advent of new technologies and the information age, consequences of globalization, are provoking deep transformations in organizations and reaching people too. This way there is the human and the social issue that goes beyond the race for profit. The new forms of management are becoming increasingly concerned with the value of human being and communication professionals, more specifically public relations, can facilitate processes and significantly improve the relationships towards positive results

A comunicação interna como fator de inovação nas Micro e Pequenas Empresas

The work presents a literature review on the topic of internal communication as an innovation factor in Micro and Small Business. The objective is to discuss how internal communication can be an essential factor in the pursuit of innovation and the consequent competitive advantage in the Micro and Small Enterprises scenario. We present the concepts of integrated communication, organizational communication, internal communication, whether crafted by a philosophy of Public Relations, can lead these companies to gain competitive advantage and overcome the limitations and challenges imposed on them

Análise do gerenciamento de projetos de produtos na área de desenvolvimento de motores em uma indústria automotiva

L'un des facteurs nécessaires pour qu’une entreprise reste compétitive sur le marché est la création ou l'amélioration d'un produit afin qu’il réponde aux besoins et aux attentes des clients, ainsi, le Processus de Développement de Produits (PDP) est essentiel. Pour la réussite du PDP, il est souhaitable de suivre un système standard de gestion de projet. L'objectif de cette étude est d'analyser la gestion de projets dans le processus de développement de produits dans l'industrie automobile afin d'identifier les possibilités d’amélioration. Par conséquent, nous avons procédé à une revue de littérature sur le sujet, analysé les lignes directrices et les pratiques du processus de développement de produit dans l’entreprise. Comme résultat, il a été obtenu que le système de développement de produits créé par l’entreprise requiert la clarification des outils utiles à la gestion de projet. Un problème de communication et de gestion des coûts a également été constaté dans le domaine du développement du moteur lourd
