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 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.

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.

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.

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.

In this paper, the main attention is focused on transient property of control input signal, we propose a novel adaptive controller for time-continuous single-input single-output linear systems with an input saturation in which i-th derivatives of the output signal (i = 1, ..., relative degree) are available. In the proposed adaptive controller, arbitrary deterministic signals can be used as an input of the reference models. It is shown theoretically that the tracking error between the controlled object output and the reference model output can converge to zero when the initial value of the tracking error satisfies a condition. Moreover, it is also shown theoretically that tracking performance can be improved by setting design parameter.

Abstract In this paper the continuous time stochastic constrained optimal control problem is formulated for the class of networked control systems assuming that time delays follow a discrete-time, finite Markov chain. Polytopic overapproximations of the system's trajectories are employed to produce a polyhedral inner approximation of the non-convex constraint set resulting from imposing the constraints in continuous time. The problem is cast in a Markov jump linear systems (MJLS) framework and a stochastic MPC controller is calculated explicitly, offline, coupling dynamic programming with parametric piecewise quadratic (PWQ) optimization. The calculated control law leads to stochastic stability of the closed loop system, in the mean square sense and respects the state and input constraints in continuous time.
The single-phase induction machine has the advantage of being powered by a single-phase voltage source. The availability of this power allows it to be widely used: electric household appliances, portable machine tools...

This paper deals with the output stabilization of time-delay systems with sector-bounded nonlinearity and disturbance. In this paper we will consider the problem of absolute stability for a class of time-delay systems which can be represented as a feedback connection of a linear dynamical system with unknown parameters and a uncertain nonlinearity satisfying a sector constraint. For a class of output control algorithms a controller providing exponential stability of equilibrium position without disturbance and L ∞ -stability for disturbed systems is proposed.
