Upon the Modeling and the Optimization of the Debiting Process through Computer Aided Non-Conventional Technologies

The debiting process of the remarkable properties materials can be managed through unconventional technologies as the complex electrical erosion. We present the modeling of the previous experimental results to obtain a mathematical dependence of the output parameters (processing time, surface quality) on the input parameters (voltage or current). All the experimental data are memorized on a database and for each particular debiting process a new dependence is built. Because all the experiments applied in the Romanian laboratories or practical applications of the nonconventional technological processes in the factories were based on the particular conditions of one activity, this papers presents the technical implementation of a computer-aided solution that keeps all previous experimental data, optimizes the processing conditions and eventual manage the driving gear. The flow-chart we present in this paper offers a solution for practitioners to reduce the electrical consumption while a technological processing of special materials is necessary. The computer program and the database can be easily adapted to any technological processes (conventional or not).

Computer Based Interpretation of the Students' Evaluation of the Teaching Staff

The goal of this paper is to offer a full support for universities and quality assessment committees in retrieving the feedback from their students regarding to their teaching staff. The computer based application presented before ([Cri07]) collects data from the students. Another part of the application, presented in this paper, processes this data and presents the statistical results concerning each teacher.

Internet: Romania vs. Europe

This paper presents various access ways to Internet for home users, both for those who are low consumers (consumed time online or traffic monthly value), or large consumers (unlimited connection). The main purpose of the work consists in making a comparison between the situation of the Internet in Romania and other countries in Europe such as Hungary (more western than Romania, so a little more developed, still an Eastern country comparing to the more developed countries in Western Europe and others well developed such as England, Italy, France, and to those in development such as Poland, and at the periphery of Europe such as Ukraine.

Computer Aided Optimization of the Unconventional Processing

The unconventional technologies, currently applied at a certain category of materials, difficult to be processed through usual techniques, have undergone during the last 60 years all the stages, since their discovery to their use on a large scale. They are based on elementary mechanisms which run the processing through classic methods, yet, they use in addition the interconnections of these methods. This leads to a plus in performance by increasing the outcomes precision, reducing the processing time, increasing the quality of the finite product, etc. This performance can be much increased by using the computer and a software product in assisting the human operator in the processing by an unconventional method such as; the electric or electro-chemical erosion, the complex electric-electro-chemical erosion, the processing by a laser fascicle and so on. The present work presents such an application based on a data base combining the previous experimental results, which proposes a method of optimization of the outcomes.

Application for Evaluation of the Professional Competencies of the Teaching Staff

The goal of the presented application is to offer a full support for universities in retrieving the feedback from their students with regard to their teachers. This is the main reason we described it in this paper. To build this application the following tools have been used: Microsoft Notepad 5.1 (to make the source files), Adobe Photoshop CS3 (to make the background image) and Adobe Flash Media Encoder 8 (to render the video clips).

Teacher's Evaluation - a Component of Quality Assessment System

One of the most important activities to increase the importance and the responsibility of the higher education is the quality management, assessment and evaluation. Starting from 2006, a national mechanism was created in Romania and all the educational institutions have to apply a concrete algorithm to ensure the internal evaluation, the external evaluation and, the most important, to increase the quality of the educational process. This paper presents the implementation of the quality assessment in "Tibiscus" University of Timisoara, particularly at the Faculty of Computers and Applied Computer Science.

Expert Software for the Determination of Juvenile People's Obesity

Keeping the health condition at the juvenile population is the concern of both the medical staff and the physical education teachers. Considering the steady tendency of the growth of the number of the youth with excessive weight (overweighted or obese) the intervention to combat this phenomenon must be initiated in the early stage when this condition occurs. The screening method for evaluating the body weight presented in this study uses a calculus program through which, based on the input data (age, sex, weight the width of the skin fold) an evaluation regarding each juvenile's weight and the body structure can be done. This program can be used in schools, high schools, universities, to signal the weight excess and to appreciate the intervention results for getting a normal weight.

About Testing the Speed of Calculating the Shortest Route

Applied into a various area of domains, the graph theory and its applications allow the determination of the shortest route. The common algorithm to solve this problem is Bellman-Kalaba, based on the matrix multiplying operation. If the graph is very large (e.g., the dimension of the associated incidence matrix is big) one of the main problems is to reduce the calculus time. This paper presents a testing method able to analyze if an acceleration of the Bellman-Kalaba is possible and able to determine the time efficiency.

Expert System for Quality Assessment in "Tibiscus" University

The periodical evaluation of the teaching staff in "Tibiscus" University is based on the specification of the Romanian Agency for Quality Assurance in Higher Education (ARACIS), namely "The quality of teaching and researching staff: The universities must dispose of teaching staff which, as number and functional base must be correctly allocated to the total number of students, depending on the study domain and regarding the qualifications it must depend on the specific of the study program and the proposed quality objectives." This paper presents the implementation of an expert system, offering to the students the possibility to perform the evaluation in a modern way and to the evaluation committee a quick access to all necessary data.
