Opis:: In this paper, the MOS differential pair driven simultaneously from gates and bulk terminals is described. An approximated analytical solution of the voltage to current transfer function has been found for the proposed circuit. Four possible combinations of gate and bulk connections of the input signal are presented. Basing on the configuration giving the best linearity, the operational transconductance amplifier (OTA) has been designed and compared, by computer simulations, to the amplifier utilizing the gate driven classic MOS pair. 3rd order filters using the OTAs with linearized and simple MOS pair have been designed and the resulting parameters have been compared. Linearization through the presented simultaneous use of gate and bulk terminals seems to be useful for low voltage applications.

Opis:: Endopeptidase marker EpD1b and STS marker XustSSR2001-7DL are closely linked to very effective eyespot resistance gene Pch1. Because of this, the aim of this study was to compare the results obtained under lab conditions using such markers with the results obtained under field conditions. 134 wheat breeding lines and Triticum aestivum L. var. Randevous used as a eyespot resistance control were analized. The combination of three methods allowed to select eight completely resistant or high resistant lines, that could be used in following breeding processes. Results obtained using endopeptidase and STS markers in 100% correlate with the phenotyping scoring.

Opis:: This paper describes the idea and the implementation of the image detection algorithm, that can be used in integrated sensor networks for environment and traffic monitoring in urban areas. The algorithm is dedicated to the extraction of moving vehicles from real-time camera images for the evaluation of traffic parameters, such as the number of vehicles, their direction of movement and their approximate speed. The authors, apart from the careful selection of particular steps of the algorithm towards hardware implementation, also proposed novel improvements, resulting in increasing the robustness and the efficiency. A single, stationary, monochrome camera is used, simple shadow and highlight elimination is performed. The occlusions are not taken into account, due to placing the camera at a location high above the road. The algorithm is designed and implemented in pipelined hardware, therefore high frame-rate efficiency has been achieved. The algorithm has been implemented and tested in FPGA and ASIC.
