Abstract: Abstract: -More applications apply in the sensor networks, people deploy sensor nodes at nature environment, modern building and war. Sensor devices are designed small shape and low weight, so the battery energy capacity is limited. Not all sensor routing algorithms can be adaptive to moving object tracking system, especially for secure and emergency sensor network, the routing algorithm do not need data aggregation, this paper main investigates a routing algorithm for tracking, it can reduce energy consumption and take long lifetime and reduce the number of dead nodes. Our algorithm is called sensor on demand betweenness vector(SOBV). When the sensor nodes send information of geographic information, human behaviors and vehicle traffics by SODV routing algorithm, SOBV is multipath routing algorithm based on the characteristics of network topology.
Keywords: Betweenness, Network model, Routing algorithm, Object tracking.

Abstract: There is a project of Autonomous monitoring system being solved at Tomas Bata University in Zlin. Within the framework of this project a small airship driven by ultrasonic detectors is being developed. This airship shall be capable of independent operation in an enclosed hall, bearing a camera or another monitoring system. There are several voltages needed to power the circuits of the airship. To ensure their feeding from a Li-Pol battery, a small and lightweight power supply has been designed. In this article, aspects of designing such power supply unit are analysed. Some attention is also devoted to the wider aspects of using the airships, mainly their advantages of low power consumption, and to the circumstances of employing the developed circuits.

Abstract: This paper deals with the problem of numerical analysis of multidimensional systems with interval parameters in relation to the operability of MIMO systems. The problem is based on the assumption that only the state matrix of a MIMO system contains interval parameters. The problem of operability estimation of the MIMO system is solved with degeneration factors. Degeneration factors are constructed using the singular values of the criterion matrices of the system. The operability analysis algorithm is realized with the interval arithmetic for the case when the relative estimation of the state matrix is more than 0.5, and with the sensitivity theory when the relative estimation of the state matrix is equal or less than 0.5. There is an example.

Number of paper pages: 10
Abstract: To improve the overall efficiency of power system, the performance of distribution system must be improved. It is done by installing shunt capacitors in radial distribution system. The problem of capacitor allocation in electric distribution systems involves maximizing "energy and peak power (demand) loss reductions" by means of capacitor installations. As a result power factor of distribution system improves .There is also lots of saving in terms of money. A 10 bus radial distribution system is taken as model. Then a load flow programs is executed on MATLAB. Then by using load flow data & fuzzy techniques the determination of suitable location of capacitor placement and its size is done. Shunt capacitors to be placed at the nodes of the system will be represented as reactive power injections. Fuzzy techniques have advantages of simplicity, less computations & fast results. The same techniques can be applied to complex distribution systems & dynamic loads.

Abstract: Natural Convection process within a closed cavity when heat source is on the vertical wall of it special importance .heat source generate constant heat flux. A common practical example of this case is electronic boards inside a computer or radiator in the room. One of the important parameters in designing electronic boards in the computer or another things is the maximum temperature of pieces; therefore we must examine the factors that affect this to have a reduced the maximum temperature. Governing equations on fluid flow mass, velocity and energy equations using the finite element method with power law, pr = 0.7, a non-uniform network is converted to algebraic form. Because of buoyancy force the Momentum equation depended on temperature. Momentum equations and energy equation are solved simultaneously. Momentum equations that include unknown pressure solve with Simple algorithm. The velocities are obtained from Momentum equation must satisfy continuity equatio!
n. Heat generation is constant. Wallfs temperature is T‡ (temperature of environment). At first velocity of fluid is . With these boundary conditions we check the effect of thermal springs placed inside the cavity, cavity dimensional, size of thermal springs (heat source) to reduce temperature. Convergence of the energy equation is 10-7. Convergence standard is temperature changes.

Abstract: Cross-linked polyethylene (XLPE) high voltage cables have been widely used in power transmission and distribution systems. Ageing deterioration of XLPE insulating material can not be avoidable due to its made of polymeric material. This paper mentions to the experimental results on artificial ageing test of 22 kV XLPE cable for distribution system application in Thailand. XLPE insulating material of 22 kV cable was sliced to 60-70 µm in thick and subjected to ac high voltage stress at 23◦C, 60◦C, 75◦C and 90◦C. The specimens were tested under different electrical stress levels varying from 50kV/mm to 130kV/mm. Testing voltage was constantly applied to the specimen until breakdown. Five specimens were tested at each temperature level and each voltage stress level. Breakdown voltage and average time to breakdown were used to evaluate life time of insulating material. Furthermore, the physical model by J. P. Crine for predicts life time of XL!
PE insulating material was adopted as life time model and was determined in order to compare the experimental results. Acceptable life time results were obtained from Crine's model comparing with the experimental result. In addition, Fourier transform infrared spectroscopy (FTIR) for chemical analysis and scanning electron microscope (SEM) for physical analysis were conducted on tested specimens.

Abstract: We present a hybrid PTL/CMOS logic synthesis method based on BDD (Binary decision diagram) and compared the results with their conventional static CMOS in terms of various design constraints as area, power and power delay product in an experimental BSIM3V3 90 nm technology. This approach uses multilevel PTL logic cells that are automatically constructed from only a few basic cells and determine the best mixture of PTL and CMOS cells using BDD. Experimental results shows that proposed hybrid PTL/ CMOS full subtractor gives best results over Pass transistor and CMOS logic based full subtractor.

Abstract: In this paper we perform a study of the effects of a close approach in the three-dimensional space between a planet and a cloud of particles, with the goal of understanding the dispersion of this cloud in terms of the variations of velocity, energy, angular momentum and inclination. It is assumed that the cloud is formed at the periapsis and the particles differ only by the magnitude of the velocity at this point. In this research we use the three-dimensional circular restricted three-body problem as the basic model for this close approach. A numerical algorithm is developed and implemented to study this problem and then it is applied to a cloud of particles, based in an analytical description of the close approach maneuver in the three-dimensional space. Analytical equations based in the patched conics approximation are used to calculate the variation in velocity, angular momentum, energy and inclination of the spacecraft that performs this maneuver.

Abstract: There are several different possibilities to change the trajectory of a space vehicle. One of the most modern engine is ion propulsion. It is expected that, to leave Earth, engines based on chemical propulsion will be used in the near future, with solar electric propulsion (SEP) making other maneuvers of the mission. This paper considers that an optimization of maneuvers will be performed in interplanetary missions using solar electric propulsion and Gravity Assisted Maneuver to try to reduce the costs of the mission. Usining the high specific impulse and the capacity of the electric propulsion to lead the spacecraft into a Gravity Assisted Maneuver with the Earth after a year of the departure of the spacecraft. Missions using the thrusters PPS1350 and the Phall 1 will be simulated for performance comparison. An indirect optimization method will be used in the simulations.

Abstract: This paper presents comparative study of contact stresses and strains at horizontal continuous casting and an innovative method of the half-finished products to horizontal continuous casting of metals. Withdrawal of half-finished products to continuous casting of metals is generally realized by using one or more pairs of metal rollers made of steel. The pairs of rollers are electromechanical and hydraulic driven. This method of half-finished products, although most prevalent, also presents drawbacks. The method proposed by the authors, using jaws firing concentrically oriented, with the half-finished product which is subject of the withdrawal operation.The proposed method is an innovative, and eliminates the hydraulic system of roller shrinkage on the profile, the necessary system in withdrawals roller case. In this way is ensure energy saving and improves facility efficiency and product quality. In terms of curvilinear wire vertical continuous casting, the authors!
propose the optimization of withdrawal cylinders. In vertical continuous casting withdrawal cylinders are generally used to withdraw several sizes and types of profiles. This is because vertical continuous casting applies only to the large semi-manufactured and change withdrawal cylinders for every size and shape of the semi-manufacturing is not economical. Thus, because the same cylinders are used to withdraw for several types and sizes of semi-manufactured products, slip and deformation may occur, which may affect product quality and reliability of vertical continuous casting. To overcome this problem, the authors propose optimization withdrawal cylinders. This optimization is done by machining the cylinder with more rays that adapts to different kinds of round shapes, but also may withdraw and blooms or billets.

Title of the Paper: A Genetic learning Motion planning of an Autonomous Mobile Robots
Authors as they appear in the Paper: Hachour Ouarda
Email addresses of all the authors: kala_ouarda@yahoo.fr
Number of paper pages: 10
Abstract: This paper describes how soft computing technology as Genetic Algorithms (GAs) can be applied for path planning of an Autonomous Mobile Robot (AMR). GAs are search algorithms based on the mechanics of natural genetics. They combine survival of the littlest among string structures with a structured yet randomized information exchange to form a search algorithm with some of the innovative flair of human search. The proposed GA approach has an advantage of adaptivity such that the GA works perfectly even if an environment is unknown. . These environments were randomly generated . While randomized, GAs are no simple random walk. They efficiently exploit historical information to speculate on new search points (sub path positions) with expected improved performance. We measure the number of generations of candidates. The coding of GA is to affect label 0 for free cell and 1 for hazardous cell. This way of work is very useful later if the substring is inherited to new ge!
nerations by genetic operators. The objective is to find a feasible and flexible path from initial area source to destination target area, flexible because the user can change the position of obstacles it has no effect since the environment is unknown. This robust method can deal a wide number of environments and gives to our robot the autonomous decision of how to avoid obstacles and how to attend the target. More, the path planning procedure covers the environments structure and the propagate distances through free space from the source position. For any starting point within the environment representing the initial position of the mobile robot, the shortest path to the goal is traced. The results gotten of the GA on randomly generated terrains are very satisfactory and promising.

Title of the Paper: The proposed Grid _Based Navigation Approach
Authors as they appear in the Paper: Hachour Ouarda
Email addresses of all the authors: kala_ouarda@yahoo.fr
Number of paper pages: 10
Abstract: Navigation is a major challenge for autonomous, mobile robots. The problem can basically be divided into positioning and path planning. In this paper we present a scheme for path finding, we focus on positioning. Starting out from an initial position in the grid, the mobile robot can autonomously head for destination cells in the grid. On its way it determines the current location in the grid using a connectivity_cell principle by picking up line-Crossing cells. This principle will be clarified in detail. A key ability needed by an autonomous, mobile robot is the possibility to navigate through the space. The focus is on the ability to move and on being self sufficient. The robot navigates on a grid which regularly divides the ground into rectangular cells. To carry out tasks in various environments as in space applications, the robot succeeds to reach its target without collisions. The proposed approach can deal a wide number of environments. This navigation appro!
ach has an advantage of adaptivity such that the intelligent autonomous mobile robot approach works perfectly even if an environment is unknown. The results are promising for next future work of this domain.

Title of the Paper: Novel Mobile Robot Path planning Algorithm
Authors as they appear in the Paper: Hachour Ouarda
Email addresses of all the authors:
Number of paper pages: 10
Abstract: In this present work we propose a novel mobile robot path planning algorithm. Autonomous robots which work without human operators are required in robotic fields. In order to achieve tasks, autonomous robots have to be intelligent and should decide their own action. When the autonomous robot decides its action, it is necessary to plan optimally depending on their tasks. More, when a robot moves from a point to a target point in its given environment, it is necessary to plan an optimal or feasible path avoiding obstacles in its way and answer to some criterion of autonomy requirements such as : thermal, energy, time, and safety for example. First, we assume that the goal position is unknown. Secondly, only obstacles in the "relevant" area (according to the logical position ) are consider, i.e. the obstacles that are far, or in the direction opposite to the movement of the robot are not relevant. In this context, a full range of "main sub_position concepts" for vehi!
cle control have been investigated by the execution of the asked mission. These feasible sub_position works demonstrate that obstacle detection and collision avoidance are improved with good results. While this model has been successful for the path planning problem, it is problematic for robots to react, act, decide, and to take a suitable action "high level reasoning". Much of the challenge of the mobile robots requires intelligence at subconscious level. In this context, the proposed path planning algorithm provides the robot the possibility to move from the initial position to the final position (target). The results are satisfactory to see the great number of environments treated.

Title of the Paper: Analysis of Intra-Person Variability of Features for Off-line Signature Verification
Authors as they appear in the Paper: Bence Kovari, Hassan Charaf
Email addresses of all the authors: beny@aut.bme.hu
Number of paper pages: 10
Abstract: One of the major challenges in off-line signature verification is the fact that a person's own signature is influenced by a number of external and internal factors. This influence results in a high variability even between signatures written by the same signer. This paper proposes a method which is able to model the intra-person variability of a signature feature and also to identify and eliminate the effects of external factors. To demonstrate the efficiency of the algorithm, a sample signature verifier is constructed and evaluated on the Signature Verification Competition 2004 database. Experiments have shown that by using 3 features (endings, loops and skew vectors) an average error rate of 12% can be achieved by the system. These results may be further improved by increasing the number of features, used during the comparison of signatures.

Abstract: Many efforts have been invested in the last years, based on sensor technology and signal processing, to develop electronic travel aids (ETA) capable to improve the mobility of blind users in unknown or dynamically changing environment. In spite of these efforts, the already proposed ETAs do not meet the requirements of the blind community and the traditional tools (white cane and guiding dogs) are still the only used by visually impaired. In this paper, research efforts to improve the main two components of an ETA tool: the Obstacles Detection System (ODS) and the Man-machine Interface (MMI) are presented. Now, for the first time, the ODS under development is bioinspired from the visual system of insects, particularly from the locust and from the fly. Some original results of the author's team, related to the new concept of Acoustical Virtual Reality (AVR) used as a MMI is then discussed in more detail. Some conclusions and the further developments in this area are!
also presented.

Title of the Paper: Softcomputing approach to segmentation of speech in phonetic units
Authors as they appear in the Paper: Mario Malcangi
Email addresses of all the authors: malcangi@dico.unimi.it
Number of paper pages: 8
Abstract: Speech-To-Text and Text-To-Speech applications are essentially based on an effective separation of phonetic units, so the segmentation of uttered speech into phonetic units is a key processing task for successfully implementing speech recognition systems. Softcomputing methods demonstrate to be more effective than other methods due to the capability neural networks and fuzzy logic to be trained by expert. This work phonetic segmentation of uttered speech that separates vowels from consonants is based on a fuzzy logic inference engine tuned by an expert using speech features distribution. Only time-domain feature-extraction algorithms are applied to speech to extract features, so minimum computational cost was achieved. Fuzzy decision logic is used to infer about phonetic units separation point. A set of tests has been executed to demonstrate that this approach can be effective in separating phonetic units, while requiring minimal computing power and reducing s!
ystem complexity.

Abstract: This paper presents comparative study of contact stresses and strains at horizontal continuous casting and an innovative method of the half-finished products to horizontal continuous casting of metals. Withdrawal of half-finished products to continuous casting of metals is generally realized by using one or more pairs of metal rollers made of steel. The pairs of rollers are electromechanical and hydraulic driven. This method of half-finished products, although most prevalent, also presents drawbacks. The method proposed by the authors, using jaws firing concentrically oriented, with the half-finished product which is subject of the withdrawal operation.The proposed method is an innovative, and eliminates the hydraulic system of roller shrinkage on the profile, the necessary system in withdrawals roller case. In this way is ensure energy saving and improves facility efficiency and product quality. In terms of curvilinear wire vertical continuous casting, the authors!
propose the optimization of withdrawal cylinders. In vertical continuous casting withdrawal cylinders are generally used to withdraw several sizes and types of profiles. This is because vertical continuous casting applies only to the large semi-manufactured and change withdrawal cylinders for every size and shape of the semi-manufacturing is not economical. Thus, because the same cylinders are used to withdraw for several types and sizes of semi-manufactured products, slip and deformation may occur, which may affect product quality and reliability of vertical continuous casting. To overcome this problem, the authors propose optimization withdrawal cylinders. This optimization is done by machining the cylinder with more rays that adapts to different kinds of round shapes, but also may withdraw and blooms or billets.

Abstract: Multiview video plus depth (MVD) data format is proposed as the main three dimensional (3D) representation that supports 3D video (3DV) system. It consists of multiview color video and multiple associated depth videos which indicate the distance between the captured scene and cameras. Due to the limitation of current obtaining depth video techniques, the obtained depth map may be not accurate. The inaccuracy will make the original continuous contents, such as background, foreground and static objects, be discontinuous in real depth map. This will result in poor virtual view rendering performance and low depth compression efficiency in 3DV system. To solve the problem, we propose a novel depth preprocessing method based on 3D perception to eliminate the errors in depth video and improve the compression efficiency of depth video in this paper. Firstly, we define a perception factor according to 3D perception of human visual system. In 3DV system, human visual attent!
ion is attracted not only by image visual attention effect, but also by particular 3D perception. Then the perception factor is utilized to decide which part of depth map should be protected and which part need to be smoothed by low-pass filtering in the spatial or temporal dimension. And then, the preprocessing depth and color videos are transformed into new videos in which a frame is composed of the same rows of pixels in original video in temporal direction. The transformed depth video is smoothened with the aid of transformed color video. Finally, the smoothened depth video is reconstructed into the final depth video. Experimental results show that the proposed method saves the bit-rate by 7.02%~48.34% in depth compression while it keeps the virtual view rendering performance.

Abstract: Nowadays, wireless sensor networks (WSNs) are becoming increasingly beneficial, worthwhile and a challenging research area. The advancements in WSN enable a wide range of environmental monitoring and object tracking applications. Moreover, multihop (node by node) routing in WSN is affected by new devices constantly entering or leaving the network. Therefore, nature in-spired self-maintained protocols are required to tackle the problems arising in WSN. We proposed ant colony stimulated routing, which shows an outstanding performance for WSNs. In this manuscript, a self-optimized (ACO) routing protocol for WSN and the results are presented. Link quality, energy level and velocity parameters are used to discover an optimal route. The signal strength, remaining power and timestamp metrics are trade in from physical layer to network layer. The emitted decision through the WSN discovery will establish the optimal route from source to destination. The adopted architecture!
helps ACO in improving the overall data throughput; especially in the case of real time traffic.

Abstract: The aim of the study reported in this paper was to undertake a study about the influence of technology in the form of products that incorporate technology, using a standard methodology developed for this purpose. Examples of products and their shape changes over time were analyzed, to understand the extent to which these changes are consequences of the developments in technology. A review of the evolution of form, taking into account the technology of a selected range of consumer products that incorporate technology, with the aim of deconstructing archetypes that are fixed and propose new ideas was accomplished. In particular, a range of technologies that are foreseen for the future were considered. Selecting specific cases of products, from a historical perspective, one can see what have been the determinants of their shape, which led to the establishment of their archetypal form. A comparative methodology was developed, in order to "decode" the role of technology!
as a determinant of the shape of products. Understanding the importance of technology as a modeling influence for products' form, what role this has in the consumer society, and what is its responsibility as a major element in the deconstruction of the archetypes of form is intended in this study. The influence of technology in the transformation of products is demonstrated, considering three distinct types of alterations caused by changes in technology, in a tripartite view, which focuses on: product changes, in the cases where technological change leads to a radical change of product form; product change, if technological change is not reflected so much in the change of form, but rather in the performance and the yield of the product; and, ultimately, change in the product in the event of technological change leading to a deconstruction of the product as an object. It is emphasized that the product as a physical object may disappear or may be dissolved in the environment!
or the architecture, with the advent of emerging technologies and the
ir new capabilities that will certainly cause changes in the shape of products.

Abstract: In the recent years, an important issue in the process for sustainable development in Taiwan village communities has emerged as that our villages has been aging and the young people and men in their prime have been moving out into the cities for job reason, which results in the improper care for community elders and children physically and mentally. Our government has thus actively promoted various health welfare measures to improve community living environment and raise the living quality of community residents. We can see from these that community health and welfare have become issues needed immediate solutions in Taiwan¡¦s communities. This study applied Fuzzy Analytic Hierarchy Process (FAHP) to examine these issues and selected three communities in Miaoli County, Taiwan for real case survey, analysis and evaluation in order to propose the best guidelines for the future references in community self diagnosis, enhancing improvement and strategies planning. Our r!
esults indicated that, to create community health, it needed particularly to strengthen: community organizational operation flexibility, spontaneous sense of community, local self-sufficiency and link with the government to form excellent communities mutually helped by industries, government, school and citizen, and to realize their advantages and improve their disadvantages thru these guidelines.

Abstract: In this paper two different oscilloscope control methods are presented. The first method is the classic method to send the SCPI commands via RS232 serial interface. The second method is to use the LabVIEW divers. The first oscilloscope is the HAMEG HM407, which has its control program implemented in MATLAB. The second oscilloscope is the NI PXI-5412 with the control program in LabVIEW. The second control program is much faster and mare simple, but with the classic method we can configure more and have a better control over the oscilloscope. The classic method is also general, because it can be controlled any oscilloscopes and equipment, even if they have no driver. In the first method the driver is made, in the second method a driver is used.

Abstract: Water Distribution System forms that component of water supply scheme which conveys water from source to destination. Effective operation and maintenance of the system depends upon the system parameters such as frictional resistance of pipes. But the ageing of the pipes changes the resistance characteristics considerably; also the leaks in the system and the unauthorized consumption's may drastically alter the behavior of the system. Leakage from the WDN apart from leading to loss of good quality water also leads to contamination of the Water Distribution System from sewer line and ground water. With a view to see the effect of leakage a steady state mathematical formulation with and without leakage for water distribution network is introduced which calculate pipe discharge and nodal head in distribution system. Following [2], these formulations have been named as pipe discharge formulations, nodal head formulation, nodal head correction formulation and loop discha!
rge correction formulation. The analysis methods on lines of method of balancing heads (Hardy Cross method), method of balancing flows, Newton Raphson method, Linear theory method and Finite element method are developed and compared. Comparative results of these methods to two simple example networks are presented. Presented formulations and analysis methods would be of great help to students, academicians and practicing engineers. This forms one of the objectives of this paper, apart from comparing them.

Abstract: The Discrete Tchebichef Transform (DTT) is a linear orthogonal transform which has higher energy compactness property like other orthogonal transform such as Discrete Cosine Transform (DCT). It is recently found applications in image analysis and compression. This paper proposes a new approach of fast zigzag pruning algorithm of 4x4 DTT coefficients. The principal idea of the proposed algorithm is to make use of the distributed arithmetic and symmetry property of 2-D DTT, which combines the similar terms of the pruned output. Normalization of each coefficient is done by merging the multiplication terms with the quantization matrix so as to reduce the computation. Equal number of zigzag pruned coefficients and block pruned coefficients are used for comparison to test the efficiency of our algorithm. Experimental method shows that our method is competitive with the block pruned method. Specifically for 3x3 block pruned case, our method provides lesser computational c!
omplexity and has higher peak signal to noise ratio (PSNR).
Keywords: Discrete cosine transform, Discrete-tchebichef transform, Image compression, Peak signal to noise ratio, Zigzag prune.

Abstract: Nowadays, wireless sensor networks (WSNs) are becoming increasingly beneficial, worthwhile and a challenging research area. The advancements in WSN enable a wide range of environmental monitoring and object tracking applications. Moreover, multihop (node by node) routing in WSN is affected by new devices constantly entering or leaving the network. Therefore, nature inspired self-maintained protocols are required to tackle the problems arising in WSN. We proposed ant colony stimulated routing, which shows an outstanding performance for WSNs. In this manuscript, a cross layer design based self-optimized (ACO) routing protocol for WSN and the results are presented. Link quality, energy level and velocity parameters are used to discover an optimal route. The signal strength, remaining power and timestamp metrics are trade in from physical layer to network layer. The emitted decision through the WSN discovery will establish the optimal route from source to destination. !
The adopted cross layer architecture helps ACO in improving the overall data delivery ratio; especially in the case of real time traffic.

Abstract: Parallel 2-point and 3-point block method will simultaneously compute the numerical solutions at two and three points respectively are suitable for solving large system of first order ordinary differential equations (ODEs) using variable step size. The Gauss Seidel iteration will be implemented for the block methods. The parallelism across the system is considered for the parallelization of the proposed methods using the Message Passing Interface (MPI) communication environment which runs on High Performance Computing (HPC). Numerical examples are given to illustrate the efficiency of the parallel implementation of the proposed method using 2, 4 and 6 processors with respect to the sequential one.

Abstract: This article deals with various techniques of VoIP attacks and VoIP communication security. These threats are divided in several categories according to their specific behaviour and their impact on the affected system. We describe effective methods to prevent or mitigate these attacks. Our work was especially focused on Spam over Internet Telephony (SPIT) as a real threat for the future and we consider spam in IP telephony to be very serious due to situation we face in e-mail communication. We have developed both an AntiSPIT tool defending communication systems against SPIT attacks and a tool generating SPIT attacks. AntiSPIT represents an effective protection based on statistical blacklist and works without participation of the called party which is significant advantage, AntiSPIT was implemented into Asterisk open-source platform and became one way of protection against the voice spam expected in near future.

Abstract: This paper represent the appropriate software support for Process Management, and those tools which are used in a whole range of Czech and world-class manufacturing production and non-manufacturing enterprises as well as in organizations and other public sector administration institutions. The innovation in the tuition process lies in the fact that this software is not used for modelling the processes within the university (the organization itself) – but rather, that the students themselves model and analyze processes drawn from real-world praxis (working practices) in manufacturing production and non-manufacturing enterprises.

Abstract: In this paper is presented a method for invariant 2D object representation based on the Mellin-Fourier Transform (MFT), modified for the application. The so obtained image representation is invariant against 2D rotation, scaling, and translation change (RST). The representation is additionally made invariant to significant contrast and illumination changes. The method is aimed at content-based object retrieval in large image databases. A new algorithm for fast closest vector search in the database is proposed as well. The experimental results obtained using the software implementation of the method proved the method efficiency. The method is suitable for various applications, such as detection of children sexual abuse in multimedia files, search of handwritten and printed documents, etc.

Abstract: A national identification number of natural persons is used by the governments of many countries in various ways. The main objective is to improve security in online services and unify authentication. In the Slovak Republic, National identification number based on birth date is currently used, which does not correspond with EU legislation. In our article we describe our new prototypes of Unique Person Identifier prepared on the basis of request of the Ministry of Interior of the Slovak Republic. The scheme is based on the idea of the Austrian system. Moreover, an introduction of proposal of an electronic system for identity management (IDM) in the Slovak Republic is presented.

Abstract: The paper presents a hybrid wireless sensor network which contains both mobile and fixed nodes, which enables the monitoring of chronic patients and their home environment via normal or, if necessary, emergency communication with long-distance transmitting system like Internet. Each patient and his/her home compose a hybrid node, i.e. a sensor node pair, one for patient (mobile) and one for his/her environment (mobile or fixed). The hybrid node is integrated in a real-time homecare monitoring system able to monitor and diagnose patients outside hospital and also to control the home/car ambiance. If the patient is transported by specially equipped car, the hybrid node becomes fully mobile. Because the number of assisted patients is time-dependent, we can consider that the hybrid node belongs to a scalable ad-hoc wireless sensor network (WSN). This WSN covers an administrative delimited area and contains a central fixed node which monitors the patients and emergency !
communication and also makes decision for the entire network. One can say that the network has three levels: basic (hybrid nodes for chronic patients), medium (general practitioner and ambulances), and high level (specific physicians at hospital and city hall services). Both nodes, mobile and fixed are presented as same as the design stages which drove to respective hardware architecture. From the software architecture it is described the communication engine because of the particularity in its implementation. Several critical tests were made for reliability of the architecture and some of the results are presented.

Abstract: A major issue in time series analysis and particularly in the study of meteorological time series is to model and to predict their behaviour. The first step to reach this goal is the data analysis. It is what we shall do in this article, focusing on the long range dependence (LRD) property. Various estimators of LRD have been proposed. Their accuracy have been generally tested using simulated time series since sometimes only their asymptotic property are known, or worse, no asymptotic property have been proved. For ten annual and monthly data series collected in Dobrudja region, for 41 years, we did the statistical analysis and we compare the results.

Abstract: An outpatient clinic is a very complex department to manage. The management of the outpatient department should given greater emphasis on its medical facilities in order to ensure the services provided are in high quality, which conforms to customer or patient satisfaction. Long waiting time for treatment at the department is always the main problem faced by the management, and even worst the consultation time is tremendously shorter than the waiting time. This situation has been a common complaint by the patients and remains to occur even though an appointment system is implemented. The implementation of inefficient appointment and inconsistent service time contributes to the dissatisfaction among patients as well as giving a huge impact to the healthcare's overall operations. Therefore, the purpose of this study is to analyze the multiphase patient flow system in Obstetrics and Gynecology Department (O&G Department) of a specialist centre by developing a simulati!
on model that illustrates the actual patient flow in the department. The Arena 7.0 software package is used to develop the simulation model in order to examine the patient flow, especially the waiting time involved. In addition, 120 questionnaires were distributed to patients to gather direct responds and opinions towards the services provided. The information gathered was used to aid the model improvement process. The result obtained from the simulation model shows that a long waiting time does exist in the system. Based on the developed simulation model, two proposed experimentation are being done to find the right solutions to reduce the patients' waiting time and at the same time enhanced the quality of services of the O&G Department. The proposed experimentation model can be effective to the system and is possible to be implemented in the department.

Abstract: The aim of this work is the depth of the snow cover computing in the desired point based on the geographical characteristics of a specific geographical point in a modeled area. The measured data are known on few places. These places are coincident with raingauge stations. These data have been collected by many continuous observations and measurements at the specific climatologic raingauging stations of Slovak Hydrometeorogical Institute. An interpolation method is necessary to obtain a representation of real situation about whole surface. The main characteristic of the interpolation computing is the fact that it is time-consuming. In paper, we present two cheap approaches of HPC. The first solution is a utilization of graphics processing units (GPUs) where the availability of enormous computational performance of easily programmable GPUs can rapidly decrease time of computing. The second one is a utilization of multi-thread CPUs. In our article we demonstrate how t!
o deploy the CUDA architecture, which utilizes the powerful parallel computation capacity of GPU, to accelerate computational process of snow cover depth using the inverse-distance weighting (IDW) method. The performance of GPU we face with OpenMP implementation of IDW method. We consider variable number of threads per CPU. The outputs are visualized by the GIS Grass tool
