Controle de velocidade e tração de rodas independentes para veículos elétricos

This work presents a proposal to replace thetraditional system of traction electric car that usesone electric motor and a mechanical differential, by two electric motors of lower power, controlled byelectronic control low cost. The proposed control isopen loop and uses the technique of Pulse WidthModulation (PWM), discrete and synchronizedaiming to reduce the generation of harmonics. The implementation of two smaller motor one on each wheel-drive distributes the weight of the vehicle, improving the heat exchange of the windings,beyond enable the power components supporting a current of 50% predicted for only one motor . The solution adopted for being open-loop, has a similar behavior to the mechanical differential, where theeffort imposed by the trajectory makes the velocity distribution between the wheels be appropriate tovehicle trajectory

Diagnóstico ambiental do Córrego Bandeirantes, município de Rio Claro, SP: parâmetros biológicos e metais-traço

This study was conducted to verify water quality and environmental impacts related to the occupation of the watershed of the Bandeirantes stream, located in Rio Claro, SP. The intention is to propose measures to enable the mitigation of negative impacts, and boosting the recovery and maintenance of the quality of water resources, preventing its complete degradation. Water analysis were performed at three different points, east, crossing the Ring Road (dirt road) and near the confluence with the Ribeirão Claro. The results indicated significant degradation of water, especially after the crossing, where it witnessed the accumulation of solid waste and easy access to the stream, both for animals as for people, due to limited riparian it. Another impact was observed the current construction of the Forum of Rio Claro in the right side of the stream studied, causing change in the landscape, change the flow properties and removal of existing vegetation at the site of work, defined as an environmentally protected area, as determined by existing law. Measures such as: restoration of riparian zones, effluent treatment, planned urban growth and environmental education of the population, would be essential to mitigate the environmental impacts of watershed Bandeirantes stream

Novo atrativo turístico para a orla de Barra Bonita - SP: memorial do Rio Tietê

Este trabalho tem como cidade escolhida a Estância Turística de Barra Bonita, município do centro-oeste paulista, conhecida pelo seu turismo às margens do Rio Tietê. Através dele pretende-se incluir uma nova atração turística na Orla do rio para atrair a atenção de um maior número de visitantes, assim como prolongar sua estadia no município. Será ela: o Memorial do Rio Tietê. Para a resolução do projeto foi trabalhado o conceito de turismo sustentável

Vocativos e o traço basicamente orientador da interação na Gramática Textual-Interativa

Within Textual-interactive Grammar, discourse markers are defined through a particular combination of linguistic features. One of them concerns the interactive role of discourse markers, and it is called “basic orientation of interaction”. As other authors have shown, this feature applies to expressions that play the following functions: Checking, Feedback, Injunction or Initiation. In this paper, we try to demonstrate that the feature under consideration also applies to Vocatives.

A simplificação como traço de um habitus tradutório para a Antropologia Brasileira em língua inglesa: um estudo baseado no corpus da oba O Povo Brasileiro de Darcy Ribeiro

The main purpose of this article is to investigate the social and linguistic behaviors of a translator, analyzing the use of simplification aspects in the translational process into English of the Anthropology developed by Darcy Ribeiro. With this aim, we used a parallel corpus composed by the work O povo brasileiro (1995) and by its respective translation, performed by Rabassa. The methodology used is that of Corpus-Based Translation Studies (BAKER, 1993, 1995, 1996; CAMARGO, 2005, 2007), Corpus Linguistics (BERBER SARDINHA, 2004) and Terminology (BARROS, 2004). We also adopted Sociology of Translation theories (SIMEONI, 1998, 2007; GOUANVIC,1999, 2005), as well as the habitus conception, proposed by Bourdieu (1980). Results show that this simplification may be found in Ribeiro’s translated texts, indicating the difficulties of conceptualizing the Brazilian universe in English

A explicitação como traço de um habitus tradutório para brasileirismos terminológicos em língua inglesa: um estudo baseado no corpus da obra O Povo Brasileiro, de Darcy Ribeiro

The main purpose of this article is to investigate the social and linguistic behaviors (the habitus) of a translator in face of cultural barriers in translation, analyzing the use of explicitation aspects in the translational process into English of the terminological Brazilianisms developed by Darcy Ribeiro. With this aim, we used a parallel corpus composed by the work O povo brasileiro (1995) and by its respective translation, performed by Rabassa. The methodology used is that of Corpus-Based Translation Studies (BAKER, 1993, 1995, 1996, 2000; CAMARGO, 2005, 2007), Corpus Linguistics (BERBER SARDINHA, 2004) and Terminology (BARROS, 2004). For data analysis, we adopted Sociology of Translation theories (SIMEONI, 1998, 2007; GOUANVIC, 1995, 1999), as well as the habitus conception, proposed by the sociologist Pierre Bourdieu (1980). We believe that, as pointed by Baker`s theories (1996), explicitation is a translator`s tendency or procedure, which explains, in the translated text, parts of the original text that have been left implicit by the author. Results show that this action may be found in Ribeiro’s translated texts, indicating the difficult of conceptualizing the Brazilian universe in English.

Estudo sobre o funcionamento de sistema de controle de tração em veículos automotores

This study explores the subject of traction control systems through bibliografy review on the spot of Mechanical Engineering. This paper has the objetivo of high light the main components and tecnology involved since MaxTrac system in 1971. It describes systems controled by throttle valve and breaks. Additionally, it i also presented basic knowlodged regarding electronic control unit and wheel sensors

Avaliação da influência do formato da porca e da pré-carga em juntas aparafusadas em tração

Many structures and mechanical equipment requires a union member, and the screw is one of the most used, the cost is low, it is versatile and easy to find on the market. The resulting pre-load assembly torque associated with the cyclical external load has great influence, so it will be studied carefully. This study analyzed some of these factors, as the format of nuts, and the washer material when they are incompatible with the bolt material can cause a reduction in life of the joint fatigue

Resistência à tração de coroas de NiCr cimentadas sobre munhões de liga de titânio, com 4 diferentes tipos de cimentos

In this work of tensile strength was evaluated the efficacy of 4 cements (S. S. White zinc phoshate, Ketac Cem Easymix glass ionomer, RelyX Luting 2 composite resin/glass ionomer and Panavia 21 TC special acrylic resin) used to fix NiCr crowns to usinated titanium alloy abutments. Were used 40 abutments distributed in groups of 10 elements, to each material. The mechanical essays were developed at a MTS 810 universal machine, adjusted to a 0.5 mm/m velocity. The ANOVA applied to data pointed out the existence of significant differences between groups; the subsequent Tukey´s test (p<0.05) also detected significant differences, except at comparisons of phosphate versus RelyX and phosphate versus Ketac Cem. The better performance was presented by Panavia 21 (1,127.996 N); RelyX (478.197 N) showed itself similar only to phosphate (430.662 N), wich had a performance similar to that of Ketac Cem (227.705 N).
