Sistema informatizado para dispositivos móveis de coleta dos dados referentes à cesta básica do município de Botucatu/SP

The collection of prices for basic goods supply is very important for the population, based on the collection and processing of these data the CLI (Cost Living Index) is calculated among others, helping consumers to shop more rationally and with a clearer view of each product impact of each product on their household budget, not only food, but also cleaning products and personal hygiene ones. Nowadays, the project of collection of prices for basic goods supply is conducted weekly in Botucatu - SP through a spreadsheet. The aim of this work was to develop a software which utilized mobile devices in the data collection and storage phase, concerning the basic goods supply in Botucatu -SP. This was created in order to eliminate the need of taking notes in paper spreadsheets, increasing efficiency and accelerating the data processing. This work utilized the world of mobile technology and development tools, through the platform".NET" - Compact Framework and programming language Visual Basic".NET" was used in the handheld phase, enabling to develop a system using techniques of object oriented programming, with higher speed and reliability in the codes writing. A HP Pavilion dv3 personal computer and an Eten glofish x500+ handheld computer were used. At the end of the software development, collection, data storing and processing in a report, the phase of in loco paper spreadsheets were eliminated and it was possible to verify that the whole process was faster, more consistent, safer, more efficient and the data were more available.

Object oriented modeling of piston engines

This work reports a conception phase of a piston engine global model. The model objective is forecast the motor performance (power, torque and specific consumption as a function of rotation and environmental conditions). Global model or Zero-dimensional is based on flux balance through each engine component. The resulting differential equations represents a compressive unsteady flow, in which, all dimensional variables are areas or volumes. A review is presented first. The ordinary differential equation system is presented and a Runge-Kutta method is proposed to solve it numerically. The model includes the momentum conservation equation to link the gas dynamics with the engine moving parts rigid body mechanics. As an oriented to objects model the documentation follows the UML standard. A discussion about the class diagrams is presented, relating the classes with physical model related. The OOP approach allows evolution from simple models to most complex ones without total code rewrite. Copyright © 2001 Society of Automotive Engineers, Inc.

NCAP embedded using structured programming

This paper presents a network node embedded based on IEEE 1451 standard developed using structured programming to access the transducers in the WTIM. The NCAP was developed using Nios II processor and uClinux, a embedded operating system developed to features restricted hardware. Both hardware and software have dynamics features and they can be configured based in the application features. Based in this features, the NCAP was developed using the minimum components of hardware and software to that being implemented in remote environment like central point of data request. Many NCAP works are implemented with an object oriented structure. This is different from the surrounding implementations. In this project the NCAP was developed using structured programming. The tests of the NCAP were made using a ZigBee interface between NCAP and WTIM and the system demonstrated in areas of difficult access for long period of time due to need for low power consumption. © 2012 IEEE.
