Desenvolvimento de um computador de bordo para veículo Baja-SAE

The objective of this paper is show the development of an Eletronic Control Unit (ECU) for Baja-SAE vehicles from its requirements to final implementation. An ECU for Baja-SAE vehicles is made of electric and electronic circuits (appropriated to the hostile situations of an off-road competition) able to make important measurements for the running or stand-by vehicle performance. For this development, some concepts were studied: embedded electronics concepts (mainly microcontrollers and data acquisition circuits) and sensoring. Both the studies were made considering the off-road environment. After these initial studies, the elaboration of the basics hardware and software (under simulations) has begun, and this elaboration objectives maximum performance and low implementation cost. After the theorical studies, basic definition of the hardware and software’s architectures and simulations, the printed circuit boards (PCB) were made, as exhaustive tests in these boards for debugging and verify if the boards work well. Once the system was tested in the university, it ran into a regional Southeast competition in 2010, that definitely proved the efficiency of the whole system

Tratamento farmacológico da epilepsia em cães

Seizure is a clinical manifestation of abnormal neuronal hyperactivity of the cerebral cortex, presentation clinical varies according to the location and extent of the brain. The classic seizure begins with an inicial period, named prodrome, followed by the aura, the ictus and finally the post-ictus phase. Seizures can be generalized or focal/partial types. Focal seizures with secondary generalization are the most common type in dogs. The seizure can be divided etiologically in intracraneal (idiopathic epilepsy; sintomatic; probably sintomatic epilepsy) and extracraneal disorders. After determining the etiology of seizures and critical analysis of the frequency, severity, and worry they cause to the owner, you should make the decision whether to launch an anticonvulsant drug therapy. Although the ideal is the elimination of seizures, the real goal should be to decrease the frequency and intensity of crises, without affecting the quality of life of patients taking the drugs used side effects acceptable. The veterinary should consider the bioavailability of the drug, contraindications, toxicity, drug interactions, the amount of daily administration, the availability of the owner and the cost of therapy. Seizures can be controlled in about 70- 80% of the dogs and in the majority of the cats when treated with Phenobarbital alone. Addition of a second drug (usually potassium bromide), decreases the number of seizures in more that 50% in about 70-80% of dogs. However, approximately 20-30% of dogs are refractory to this treatment. In these cases, it will be necessary to think in other pharmacological alternatives, like felbamate, gabapentin, levetiracetam, zonisamid, among others. It has been concluded that...

Avaliação de funcionamento das bombas hidráulicas do sistema de tratamento de efluentes da Empresa Parker Hannifin

On the field of the projects of hydraulic systems exists a lot of worries when we talk about the calculate of hydraulic pumps. In this case some facts must be considerate: length of tubes, fluid characteristics, height gauge, temperature, pressure, characteristics of tubes, flow required and others. For that mathematic calculates must be developed with the objective to optimize hydraulic pumps and agree to find an ideal machine (that don't requires more energy than necessary or less energy than it requires; that is the more critical case, cause exists the risk that the fluid pumped do not agree to become in your destiny). The wrong calculate of this machine can super-size its, bringing an excessive energy consumption. Actually it's an important subject because we are in the age of lack of energy what turn it more expensive. So the correct sizing of a hydraulic pump is connected with the fact that you have to uses the enough energy resources avoiding waste. The calculate of ideal pump in the pumping system is studied during years and a lot of specialists in this subject develop equations and theories to calculate its. Some researches study about this subject and all of them become to the same conclusion: to find the ideal pump we have to know the characteristics of fluid (cinematic viscosity), the required flow , overall yield (overall of motor x overall of pump) the high gauge or discharge pressure and the loss of repression. The pressure drop can be calculated with different theories: using Hazen-Williams, Darcy e Weisbach or Chézy (1775 - that starts the researches to calculate the pressure drop). Although the most used theory and what is most near to reality is the Darcy's equation. So, in this job the Darcy's equation were choice to calculate the drop pressure that consider what kind of flow we are studying: laminar or turbulent. The determination of the best pump to be used in the ... ( complete abstract click eletronic access below)

Aspectos formais da trilha musical de Yasunori Mitsuda para o game Chrono Cross e sua interação com o enredo

This work has the aim of evince compositional tools used in the development of musical scores for role-playing videogames through the analysis of Yasunori Mitsuda’s music for Chrono Cross (1999). This research is divided in two main parts: the first traces a historic path of the RPG genre on videogame consoles, since its birth as a tabletop game in the decade of 1970 until its consolidation on 3D game machines released in the 1990’s. The focus of this historical study concentrates on the aesthetics of this kind of game and on the multiple relations it settles with sound throughout the years. The second part is an analytical work on an assortment of pieces by Mitsuda for the aforementioned game, bringing up the most interesting aspects of the connections established between these compositions and the whole game.

Jogo baseado em simulação de vida artificial

The market of digital games have grown in the last years, becoming popular between many ages, the number of smartphones and tablets users have also showed a recent increase, including the ones using Android as operational system. The main objective of a digital game is the ludic activity but also it can be used as a tool to education, learning and even simulation. This work proposes the development of a game for smartphones or tablet running on Android operational system, this game will simulate living beings in an environment, each one with different behaviors, based in the concepts of artificial live, cellular automata and emergence. This way simulating the behavior of a living being community with a computational base in artificial live and following concepts of game design. The game can represent visually some characteristics of living beings, as well behaviors and interactions between them, in a very simple way. The game can be upgraded in the future to represent better living beings using more details to the simulation of these

Desenvolvimento de um código computacional para simulação e análise de espectros atômicos

The aim of this work was the development a computer code for simulation and analysis of atomic spectra from databases constructed from the literature. There were created four routines that can be useful for spectroscopic studies in the atomic processes of laser isotope separation. In the first routine, Possible Transitions, the program checks the possible electron transitions from an energy level of the atom present in the database considering the selection rules for an electric dipole transition. The second routine, Locator Transitions, checks the possible electronic transitions within a user-specified spectral region. The routine Spectra Simulator creates simulated spectra using the graphical application gnuplot through lorentzian curve and finally, the routine Electronic Temperature determines the temperature of electronic excitation of the atom, thought the Boltzmann Plot Method. To test the reliability of the program there were obtained experimental emission spectra of a hollow cathode discharge of dysprosium and argon as a buffer gas. The hollow cathode discharge has been subjected to different values of operating currents and pressure of inert gas. The spectra obtained were treated with the assistance of program routines developed (Transition Locator and Spectra Simulator) and temperatures electronic excitation of the atoms of dysprosium in the different discharge conditions were calculated (routine Electronic Temperature). The results showed that the electronic excitation temperature of the neutral dysprosium atoms in the hollow cathode discharge increases with increasing current applied to the cathode and also by increasing the gas pressure buffer. The determination coefficients, R2, obtained by the Electronic Temperature routine using the linear adjust of the Boltzmann Plot Method were greater...
