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 study, intelligent control of human eye movements system for the emotional support by a huggable pet type robot via Gaussian RBF neural network based on sliding mode control is presented. Despite active research and significant progress in the last three decades on control of human eye movements, it remains challenging issue due to its applications in prosthetic eyes and robotics. The geometry and model of human eye movements system are investigated and this system is considered as a nonlinear control system. The specified model may only be an academic exercise. It can have scientific importance in understanding of the human movement system in general. Also, it can be useful for robotics. By using Gaussian RBF Neural Networks Based on Sliding Mode control, the control goal can be achieved. The adaptation laws of designed controllers are obtained based on sliding mode control methodology without calculating the Jacobian of the system. The proposed method is capable to control of human eye movements system. Intelligent methods such as artificial neural networks are proposed to control the human eye movements and numerical simulations are presented. It is concluded that the intelligent controls applied to control of human eye movements system are emulated from the neural controls in biological system. © 2011 IEEE.

This paper presents a design and measurements of multichannel integrated circuits dedicated to recording of neurobiological signals. 64 recording channels have been implemented in a single chip using a commercially available CMOS 180 nm process. A single recording amplifier consumes only 25 μW from 1.8 V supply and occupies 0.13 mm 2 of the silicon area. Its main parameters such as the low/high cut off frequencies and the voltage gain are controlled thanks to the on-chip register. User is able to change the low cut off frequency in the 60 mHz - 100 Hz range in each channel independently while the high cut off frequency and the voltage gain can be set to 4.7 kHz / 12 kHz and 139 V/V / 1100 V/V respectively. The input referred noise depends on the bandwidth of the recording channel and is equal to 3.7 μV (100 Hz - 12 kHz) or to 7.6 μV (3 Hz - 12 kHz). This paper deals with problems that are present in a multichannel integrated recording electronics for neurobiology experiments such as: ability to record input signals in the frequency range below a single Hz, and the spread of the cut off frequencies from channel to channel in such systems. Up to our knowledge the solution presented in this paper is the first one reporting the multichannel IC that is able both to record extremely low frequency signals in each channel with a small spread of this parameter from channel to channel.

The electric power is indispensable for modern life. However, there is a problem of harmonic disturbance when the harmonic power runs into electronic devices. To overcome the problem and realize a stable supply of the electric power is an important issue. In this study, we have developed a voltage-current waveform telemetry system for the remote measurement of the harmonics in the power delivery lines. The system consists of sensors, preamplifiers, a single board computer, and power collectors. Improvements are made on all of these components except the sensors. The power collector is a coil that can be placed around the same power line that we measure. We have designed the power collector by a finite element method(FEM) so that it can provide enough electricity for the computer to work properly. Thus, no other power source such as a battery except the secondary rechargeable battery for the recovery is necessary at the measurement place. The preamplifier in the new system is a single-supply differential amplifier circuit, and the single board computer has an inexpensive SH-3 CPU. Through experiments, we have confirmed that the power collector can provide sufficient electricity and that the new system can successfully measure the waveforms and the harmonics in power delivery systems. © 2011 The Institute of electrical Engineers of Japan.

Motion detection is an important computer vision problem that has been used in different applications including surveillance. Most of the applications require fast processing due to their real time nature. The GPU (Graphic Processing Unit) is used as a cost-efficient tool that provides great opportunities for parallel processing. This paper studies the performance of the GPU in implementing a realistic motion detection application and compares the performance of multiple GPUs and CPU for this class of applications. The experimental results have shown that the GPU based system demonstrated high speedup and it is therefore a good low cost solution for real-time scenarios such as in video surveillance systems.

Parkinson's disease is a neurodegenerative disorder and is associated with motor symptoms, including tremor. The DBS (Deep Brain Stimulation) involves electrode implantation into subcortical structures for long-term stimulation at frequencies greater than 100Hz. The mechanism by which chronic, electrical Deep Brain Stimulation with high frequency, suppresses tremor in Parkinson's disease is unknown, but might involve a gradual change in network properties controlling the generation of tremor. First, we performed linear and nonlinear analysis of the tremor signals to determine a set of parameters and rules for recognizing the behavior of the investigated patient and to characterize the typical responses for several forms of DBS. Second, we found patterns for homogeneous group for data reduction. We used Data Mining and Knowledge discovery techniques to reduce the number of data. Then, we found "clusters" the most well-known used and commonly partitioning methods used: K-means and K-medoids. To support such predictions, we develop a model of the tremor, to perform tests determining the DBS reducing the tremor or inducing tolerance and lesion if the stimulation is chronic.
