The objective of the work is to present, analyze critically and illustrate the possibilities of implementing the decomposition model of price effects in the works of E. E. Slutsky, the known American economist. Starting from the author's idea that the height of real consumer income is determined by the attainable quantity of goods along with available income and consumer use optimization, some decomposition...
Problems associated with introduction of data in modern models are a challenge in terms of interaction between legacy systems and new technologies. The necessity of adapting old system data structures is reflected primarily in economic non-viability of modernization of those systems, which are operational and functional and where changes to the system might hamper the utilization of the old recorded...
Management of change requests and problem reports for ICT systems, no matter if they are related to software, hardware or documents, plays very important role in the maintenance, documentation and planning of systems. These change requests and problem reports can be specified by any person during the whole life cycle of the system. This paper presents an approach in integrating maintenance concepts...
By the recent trends the households have a lot of intelligent, programmable electricity consumer devices and some generation units as PV too. The new network structure of the residential inhouse power systems suits to the requirement of the security, autonomy, renewable generation and economy. This suppose a parallel DC network that get directly the PV generation, stores that, supplies the LED lighting...
This paper describes the functionalities and characteristics of a system used for mobile learning. It describes how such a system can be implemented, and what must be taken into consideration for the deployment of the system on mobile devices. It is also mentioned how the system can be further upgraded in terms of functionality.
This paper deals with a topic of phonetic search in text form, which is a type of string matching algorithms. It describes a proposed solution for phonetic searching of the Slovak and neighborhood languages surnames. This solution was designed to improve a search precision and recall for persons with the surnames originated in these languages.
Wide application of computers in teaching and learning processes has not solved the problem of integrated description of classroom objects in these environments. This description would be beneficial at the application of advanced modeling and simulation in higher education processes towards a more intelligent application of computers. The authors analyzed some results in this area and published findings...
The presented path-guidance system is able to learn movements and to predict motion. It shall enhance safe navigation for surgeons in minimally invasive surgery by creating a virtual fixture which holds the end-effector's motion to a desired path and warning the surgeon in a dangerous situation. Surgeons can demonstrate interventions and best practices. The system collects information from surgeon...
The paper describes a concept of software tool for development of nodes localization in large wireless sensor network. The basic module is the event driven simulator that enables loading position of wireless network nodes, description of the behavior of nodes, description of the environment and modeling of wave propagation in defined space. Node localization and deployment problem in wireless sensor...
This paper presents two test systems, the first with Agilent equipments and the second with National Instruments equipments. A comparison will be made about the characteristics of each. In each test systems will be presented the three main equipments which are compulsory for a functional test system: power supply, multimeter and function generator.
This paper describes the process of preparing panoramic pictures for the presentation module of our 3D city agglomerations visualization system. First, script creation is discussed, which allows the smooth redraw of model given by the transition path. Second part of the paper deals with rendering settings for photorealistic outputs. Third part is about using network rendering for speeding rendering...
Integration and adding intelligence are essential objectives in development and application of information systems. An old wish of engineers is to have a highly integrated system for the handling of all necessary information during the entire lifecycle of an industrial product. Development of modeling and simulation based product lifecycle management (PLM) systems grounded the realization of such...
Determination of project completion time is crucial for considerable number of projects, especially for the time-terminated ones. Experience showed that it is not enough to use standard network planning methods (CPM/PERT) only, particularly for stochastic projects like research and development ones. In this paper, the project time determination is based on superposition for defined network diagram...
For an automated classification of heart murmurs there is a need of detailed analysis of heart sounds both in time and frequency domain. In this work the possibility of extracting the formant frequencies from the phonocardiogram was examined. The purpose of examination described here was to obtain a result which could facilitate the classification by offering additional information about the sound...
Surrogate data method is commonly required to confirm the non-accidental nature of simultaneous fluctuations of heart rate (HR) and blood pressure (BP) due to the spontaneous baroreceptor reflex (sBRR) mechanism. Previously proposed finite, ergodic Markov model with memory, enables derivation of all BRR temporal parameters for isodistributional (ID) surrogate data in closed form, thus eliminating...
The performance of a classification model depends not only on the algorithm by which the model is learned, but also on the training set. Manual annotation of the training data is a tedious and time consuming job. In order to overcome the problem of laborious hand-labeling of a large training set, a set of techniques called semi-supervised learning was designed. Co-training is one of the major semi-supervised...
This paper proposes modeling of MetaLex/CEN compliant legal acts based on MetaLex/CEN working group proposal and specific legal act drafting guidelines. XML model of drafting guidelines of the Parliament of the Autonomous Province of Vojvodina compliant with MetaLex/CEN working group proposal is created to illustrate the modeling.
This paper deals with the implementation of mobile measuring station in greenhouse environment navigated using potential field method. The function of a greenhouse is to create the optimal growing conditions for the full life of the plants. Using autonomous measuring systems helps to monitor all the necessary parameters for creating the optimal environment in the greenhouse. The robot equipped with...
Preferansz is the Hungarian version of the Preference card game. An on-line realization of this game is presented. The PrefiOnLine software system is designed to handle hundreds of parallel games without overload problems. The architecture of this system is briefly described. Some possibilities for creating robot players are discussed. Two different AI methods for controlling robot players are described...
Very often important process variables which are concerned with the final product quality cannot be measured by a sensor or the measurements are too expensive and often not reliable. In order to enable continuous monitoring of process variables and efficient process control, soft-sensors are usually used to estimate these difficult-to-measure process variables. Soft-sensor is based upon mathematical...
