The purpose in this study is constructing digital filter with application of modern microprocessor systems, learning methods of automatic projecting and perfecting skills of programming in language of assembler. In this study, the microprocessor of firm MICROCHIP PICl 6C711 is used which has possibilities of analog signal's processing. DAC is not a part of the microcontroller and it is carried out separately, its entrances are connected to port B. The program written in language of assembler is universal for all microcontrollers of MICROCHIP having a possibility for analog signal's processing. It is necessary to configure ports and to consider specification GPR (General Purpose Register) and special registers according to the documentation on demanded model. © Medwell Journals, 2011.

If identification of the stationary logical object (LO) is understood to be its identification with an adequate finite-automation model among set of finite automation, in cases where two completely different aims (object logical structural model construction and device logical control) are being pursued, serious contradictions might arise. With the help of an adequate model received, one tries both to construct appropriate structural model of the computing unit (CU) and consider the object as a control object (CO) to control it. It goes without saying that during the development of the controlling unit of CO, which represents the logical object, its structural model is also being under construction and the object identification, the digital signal processor (DSP), is used as the main central process unit for its high control ability and computing power. Through the introduction of a rough set theory into the multi-sensor information fusion technology, the principal distinction between finite-automation identification for development of the logical structure object model and for logical control of the technological device is shown in this paper. In this work, the conversion of potential dynamic technological object to the guided dynamic object is achieved. It is possible to reach the object of self-control. ©2011 Academic Journals.

In this study, we investigate the usability aspects of the website interface design by introducing the design and implementation of a system named Web Interface Evaluation (WIE). This system evaluates the web interface through a study on a number of web interface features about 55 features extracted from different HTML web pages, English and Arabic ones and then classify these pages to high, middle, low quality, this is done by the comparison of the extracted features with threshold values. These threshold values were extracted based on an extensive survey of design, recommendations from recognized experts and usability studies. © Medwell Journals, 2011.
