This paper presents the Web service ldquoE-boardrdquo which is now in test phase at the Polytechnical Engineering College in Subotica. The capabilities of this system and various aspects of advanced information distribution are described in this article. The Web service was developed by use of following technigues: XHTML, CSS, JavaScript, PHP, AJAX, MySQL and XML. E-board is available at the following...
This device is a two-independent-front-wheel-driven robot vehicle. Each of the two front wheels is driven by an engine. The steering and running of the device is insured by these two engines. The vehicle is running on a given path with a given speed due to control circles. By increasing the number of sensors annexed to the control part of the robot vehicle, the device obtains wider autonomy.
The idea of knowledge approximation is naturally rooted in the usual examples of approximation in our experience. More abstract approximation, at the levels of syntactic structures representing knowledge, is becoming a need in the existing knowledge management, addressing a variety of important issues. Here we propose a method and its implementation, which generalizes the unification method to the...
The paper describes an algorithm model for loading low density parity check (LDPC) matrices. The paperpsilas main purpose is to present an algorithm solution which enables LDPC matrices to be loaded, providing more rapid and efficient application of analysis of error correction codes.
The problem of correct radio telemetry can only be solved if the signal is preprocessed. This work presents the pre-distortion and reconstruction process of a real time signal, and its effects.
Several years ago, at the Polytechnical College in Subotica, our own framework was implemented (our own framework) for distributing an e-learning curriculum via Internet for the following subjects: ldquoC++ programming languagerdquo, ldquoEnglish languagerdquo, and ldquoInternet technologiesrdquo. Those Web applications had numerous options, which was thought would help students in the learning process...
This paper demonstrates an efficient solution of teaching and education in computer laboratories. This article represents the continuation of research in the form of actual realization of a machine with many operating systems using virtual machines. In the current paper a solution is portrayed for the problem of distance control and administration of this system. The system is created using bash scripting...
This paper presents the realization of real embedded systems on the Internet. The experimental board communicates directly with the sensors to receive signals and to activate the actuators. The user interface on the client side is designed using HTML software. The Web server runs directly on the PIC microcontroller. A client-server application is set up for access over the Internet network in order...
This paper presents the development of Web based modular information system for the needs of distance learning. The capabilities of this system and development phases are described. This information system is developed by use of following techniques: XHTML, CSS, JavaScript, PHP, AJAX, MySQL and XML. For object oriented modeling UML is used. The information system will be available at the following...
Here, pattern formation on GaAs (001) surface after electrochemical layer removal with the help of image processing was investigated. The morphology of GaAs surface shown fractal behaviour under non-selective etching conditions. The morphological surface study was carried out using digital image processing of scanning electron microscope data. The surface patterns were segmented by the so called grade...
Machine learning presents the often used technique in natural language processing. The choices of learning algorithms, their realizations and practical applications are more than heterogeneous. This paper presents the review of memory based learning organization, the concepts of well-known k-nearest neighbor algorithm and its application in the conversion of texts.
There are considered two cases of the real semiring with pseudo-operations: one, when pseudo-operations are defined by monotone and continuous function g (then the pseudo-integral reduces on g-integral), and the second semiring ([a, b] , max, odot) , where odot is generated. There is proven a generalization of the Jensenpsilas inequality for the pseudo-integral.
The work considers the complex problems of dynamic optimization of exploiting resources that are not renewable. The analysis starts from the so-called Hotelling rule, the base for the theory of dynamism of exploiting these resources. Taking into consideration the appropriative suppositions and limitations, as well as the application of contemporary mathematical and diagrams analysis, the work attempts...
The superposition principle is a useful tool for constructing new solutions of ordinary and partial differential equations. Therefore, through this paper, we are considering the pseudo-linear superposition principle based on generated pseudo-operations of the following form: x oplus y = g-1 (g(x) + g(y)) , x odot y = g-1 (g(x)g(y)) , where g is a continuous generating function. Some possibilities...
