In this paper are introduced basic magnetic resonance (MR) methods for measuring the properties of the conductive gel structure during polymerization, particularly relaxation times T1, T2. Gel electrolytes based on the NaClO4 inorganic salt was measured. The measurement deals with 23Na nuclei. In our case to measure relaxation time T2, the Hahn echo was used. To measure relaxation time T1, the IR techniques (Inversion Recovery) was used. The value of relaxation time T2 is obtained by approximation of spectral lines and the value of relaxation time T2 is obtained by approximation of spin echo decline signal with two exponentials using a genetic algorithm for both times. The change of relaxation times T2 and T1 of 23Na nuclei during polymerization process indicate a change in the internal structure and chemical composition of gel electrolytes based on NaClO4.

The article deals with initial research into the methods of microscopic image processing methods for the study of diverticular disease. Functional and structural changes were found in tissues of persons afflicted with diverticular disease in previous medical research. The acquired images were processed manually. The goal of research into image processing methods for automatic or semiautomatic processing followed by manual supervision is to simplify and speed-up the image processing and evaluation of object parameters. The research is focused on increasing the accuracy of and speeding up the evaluation of tissue properties. ImageJ plug-ins implementing the proposed algorithms were developed for five kinds of image processing: circular muscle layer, longitudinal muscle layer, myenteric plexus layer, interstitial cells in myenteric plexus layer and interstitial cells of cajal in smooth muscle layer.

Recently, fiber optical communication and Orthogonal Frequency Division Multiplexing (OFDM) method are combined to obtain both advantages in a communication link called CO-OFDM. In this research, bit error rate (BER)-Distance variations are investigated for a constant signal to noise ratio (SNR) in CO-OFDM systems. Results also show the performance of the CO-OFDM system at different data rates and distances for one RF carrier and one optical carrier. There are 111 channels (C and L bands) can be used (191.4 to 185.9 THz) at 50 GHz spacing according to the Telecommunication Standardization Sector (ITU-T) standards. Wavelength Division Multiplexing (WDM) is the key factor to reach 1.7 Tb/s (111∗16 Gb/s) using only one optical cable utilizing C and L bands. In this research, CO-OFDM technique is modeled and simulated designing a Monte Carlo simulation. To the best of our knowledge, this work shows the first BER-Distance variations in a CO-OFDM communication link.

The method of the extraction of spatial information from 2-channel audio signal is presented in the paper. The proposed algorithm will be used to recover true spatial acoustical field for 5.0 surround system from archival 2-channel stereo recordings. There is a lot of such recordings (digital as well) which can be more attractive, when post processed to 5.0-channel standard and reproduced in home theater systems. The idea of the proposed approach is based on special utilization of amplitude-phase dependencies in input audio signal. The author have created a nonlinear algorithm of spatial information which intelligently splits 2-channel sound to 5 output channels in DTS (or Dolby Digital) 5.0 format. The proposed algorithm is also compatible with analog Dolby Surround coding. The efficiency of the method is proven objectively and subjectively. Author has also presented simple method of graphic presentation of received results. Thanks to combination of diagrams it is possible to estimate fast a quality of spatial effect. Effectively of presented sound spatialization method has been compared to known matrix Dolby Surround system and recordings made in multi-channel Dolby Digital 5.0 system.

Patients with Parkinson's disease (PD) usually suffer from hypokinetic dysarthria (HD), which involves impairment of phonation, articulation, prosody, and speech fluency. Our paper deals with parameters that can be used for the evaluation of motor aspects of speech and relevant methods of data acquisition and analysis. A review of specific parameters of HD and methods used for their evaluation may from the practical point of view contribute both to the diagnostic approaches to HD and to the development of suitable measures for assessment of its progression. The paper gives a description of the most frequently used parameters and their optimization to enable the best possible automatic classification of the various stages of Parkinson's disease.

In this paper, results of extensive research concerning synergy of dynamic routing and interconnection charging methods are presented. The impact of various dynamic traffic routing methods on different performances of interconnected telecommunications network with the application of bill-and-keep interconnection charging is analysed. For the purpose of our research, we developed the software for Routing and Interconnection Simulation — RIS. Analysing obtained results we noticed that with application of some routing methods, there are several links completely unused. We introduce the new load balance routing method in order to improve some performances of interconnected next generation networks — NGN.

The paper presents the design of a CMOS integrated circuit whose output voltage varies linearly with temperature. This sensor is implemented using two classical cross-connected current mirrors. The voltage value is read on the resistor of the lower Widlar mirror. We examined how the output voltage varies with temperature considering the open-output circuit. The sensor's design is made using resistors with negative, null or positive temperature-coefficient values. Circuit performance shall be emphasized when NTC and PTC resistor pairs are used. The maximum slope was computed for the output voltage and the maximum slope condition was estimated too. The circuit was sized to fit a maximum slope, thus resulting in a 6.27% error between the analytical and the simulated slope. The sensor's performance parameters are: the optimized output voltage slope (3.2813mV/°C), the optimized percentage slope (0.1946%/°C), low current consumption (30μA measured at 20°C), VDDmin of 2.8V, and supply regulation of 4289ppm/V at 3.5V. The sensor occupied-on-chip area is also small: 3075μm2. The total percentage variation of the output voltage slope with the manufacturing process is 25.4%, while the total variation of the output voltage with the manufacturing process amounts to 31.1%

Wireless Sensor Networks are by nature deployed over an undetermined geographical area with uncountable number of nodes, which makes them best studied through simulation. Due to special characteristics of these networks a number of simulation tools have been introduced by institutes and individuals each with different mechanisms and approaches. Hence, selecting a proper simulator based on the network under investigation is of vital role for the researchers. This paper provides a performance analysis of one of the renowned simulators, namely Castalia, through various scenarios and multiple cases. The study introduces some performance metrics which reflect different aspects of the tool and shows that Castalia is sensitive to large number of nodes in terms of execution time.

The optimal filter length of linear prediction (LP) model of musical signals are compared with speech signals in the paper. These musical signals are single musical instruments and vocal. Firstly, the global and segmental optimal orders of LP model are defined then the global optimal orders of LP model are measured for appropriately chosen musical and speech signals and finally statistical tests are performed. These tests determine if the differences between measured optimal orders are statistically significant or not.
