Enhanced Multivariance Product Representation (EMPR) method is used to represent multivariate functions in terms of less‐variate structures. The EMPR method extends the HDMR expansion by inserting some additional support functions to increase the quality of the approximants obtained for dominantly or purely multiplicative analytical structures. This work aims to develop the generalized form of the EMPR method to be used in multivariate data partitioning approaches. For this purpose, the Generalized HDMR philosophy is taken into consideration to construct the details of the Generalized EMPR at constancy level as the introductory steps and encouraging results are obtained in data partitioning problems by using our new method. In addition, to examine this performance, a number of numerical implementations with concluding remarks are given at the end of this paper.
Scheduling in traditional distributed systems has been mainly studied for system performance parameters without data transmission requirements. With the emergence of Data Grids (DGs) and Data Centers, data-aware sched...

This paper deals with the battery life of mobile devices and PDAs at various load levels of the battery. For such testing of PDA battery life, there are many programs in ensuring the current battery status. Our developed appplications can determine the battery at defined time intervals and display its status on the device display in numeric format XX%, where the measured value is stored in an external file in XLS format. Addressing problem is designed to store the measured data of the appplication in tabular form, for better evaluation performance and the subsequent effect on the battery. Testing is focused on the impact of various device appplications, that means from low-end appplications to very demanding appplications with Wi-Fi, Bluetooth, GPS, for the battery status.

The aim of this work is to create application for mobile devices such as PDAs running under Windows Mobile. With this application, and PDA it will be able to process the analog data measured by the A / D converter and display it in graphs. Use of the converter has four analog inputs. These are converted into digital form and transmitted via the communication interface Ethernet to WiFi router. Application running on a PDA uses WiFi connection to download measured data and to processes them. The advantage of this solution is particularly small size and mobility of the PDA. This eliminates the need to transfer the measuring device. This makes a possibility of usage wide especially in the manufacturing industry in the halls where it should be measured in several places at the same time, and the values compared between each other.

In many desktop applications, an audio signal is captured from the microphone. Unfortunately, most applications lack quality visual indication of arousal microphone volume, which would clearly provide to users (surveillance) information on current values and, if so achieved within a short past. The usability of applications could be in using it as an acoustic monitoring or as a visual area, or volume level for the detection of a communication program. Usability is, of course, also in programs for recording and monitoring audio. The component is designed in .NET Framework.

This project consists in developing applications for mobile phones that allows users to query using the touch screen to check the status of remote devices. Current status of the remote visualization device is arranged on the display, thereby increasing user comfort when operating the remote device (currently designed for GSM communicator GD-06 Allegro), instead of the traditional communication via SMS. Applications for mobile devices is designed for. NET Compact Framework and is designed for Windows Mobile. This application is created in Visual Studio 2008 from Microsoft.

This project is carring out of design and development of software which is able to determine the ideal method of passing cars sweep so that the car is capable of a corner as quickly as possible without compromising safety to crew, or there is a deterioration in passenger comfort, or damage to tangible property transported. Thus a virtual model of a situation such as a desktop application programming in Microsoft Visual Studio 2008 was created. Thanks to the user who made aplication used as an example of automated driving. At the same time it can become the basis for further work on this topic.

The project is to create an application that converts the audio signal from your computer microphone to record format MP3. Application is designed to record and preserve the audio recordings to a file in a format of lossy compression of audio file compression based on MPEG algorithm (Motion Picture Experts Group). While maintaining a relatively high quality it can reduce the size of audio files in CD quality at about one tenth, for speech, however, it gives much worse results. The advantage of this application is the ability to set frequency range (the sampling) and set the width of the stream, which indicates the number of bits, by which a second of record is registred with. The application is written in C # using Microsoft Visual Studio 2008.

Radio Frequency Identification (RFID) is a popular automatic identification and an emerging wireless technology with highly promising applications. In an RFID system, the anti-collision algorithm is one of the primary mechanisms to address the issue of multi-object identification. This paper focused on a detailed study of the ALOHA anti-collision problem and a comparative study with the basic binary tree protocols. Two tag estimation methods were investigated and a performance analysis was successfully achieved based on various key design parameters such as the probability of a successful transmission, the collision ratio, the offered load, the system efficiency, the system throughput and the estimation accuracy of successful transmission.
