Design of Semi-Adaptive 190-200 KHz Digital Band Pass Filters for SAR Applications
Technologies have advanced rapidly in the field of digital signal processing due to advances made in high speed, low cost digital integrated chips. These technologies have further stimulated ever increasing use of signal representation in digital form for purposes of transmission, measurement, control and storage. Design of digital filters especially adaptive or semi adaptive is the necessity of the hour for SAR applications. The aim of this research work is to design and performance evaluation of 380-400 KHz Bartlett, Blackman and Chebyshev digital semi adaptive filters. For this work XILINX and MATLAB softwares were used for the design. As pert of practical research work these designs were translated using FPGA hardware SPARTAN-3E kit. These were optimized, analyzed, compared and evaluated keeping the sampling frequency at 5 MHz for 64 order. Both these filters designed using software and hardware were tested by passing a sinusoidal test signal of 381 KHz along with noise and the filtered output signals are presented.

Embedded system based water distribution rationally for homes using RFID Technology
Now a day we are facing drinking water problems in our life. In course of time we will more struggle of this problem due to shortage of the drinking water, since water is more essential for every family or every human to live, in parallel ground water level is going down gradually. In this paper we have designed and implemented an embedded system based water distribution rationally for homes using RFID Technology, which can be organized in streets and required places. In this system only authorized members can obtain the required water for homes. This system consists of various devices like, microcontroller, keyboard, LCD, RFID reader and stepper motor. The RFID reads the id number from passive tag and sends to the microcontroller, if the id number is valid then microcontroller request to the authorized person’s password. After verifying the password the microcontroller request to enter the required water quantity (eg.50 liters per day), then the controller sends the control signals to open the gate vole by stepper. This system is more constructive to protect the wastage of waters and man power is reduced. Here the water filling of main tank, based on bore well water level is automated.

Grouping strategies in Collaborative learning –An experimental Study
In a typical class room with students of different learning styles and influences due to cultural or social factors, monitoring the individual student can be enhanced by going through their interaction with each other through a collaborative learning approach. We propose a model of two types of collaborations. The first allows dynamical grouping driven by the students’ performance within heterogeneous (mixing high, medium, low marks achievers) or homogeneous (similar marks achievers). The second type consists of static groups (the students agreed to form fixed groups, not moving from one group to another group). We have applied the two types of model in constructing the knowledge for Java coding for application development through collaborative learning process in which each student has a more or less equal role in bringing out the outputs for the laboratory exercises. Our results prove that the static groups have significant effect in spite of the presence of extra encouragement for participating in dynamic grouping. This result establishes, especially in the context of rural learners in, the evidence of gaining educational benefits from the social interactions and cultural factors.

A comparative study on body composition of Shyrbot (Barbus grypus) fish reared in different salinities
Effect of different salinity on body composition of shyrbot fish was investigated. Shyrbot fingerlings with an average weight of 3.96 grams were reared under different salinities (0, 3, 6, 9, 12 and 15g). Analysis of body composition showed a significant effect of different levels of salinity on protein, fat, moisture and ash (p<0.01) of the fishes. The highest level of protein, ash and moisture and lowest amount of fat were obtained in 15ppt salinity followed by 12 and 9ppt salinity. The highest amount of fat was obtained in freshwater followed by 3 and 6ppt. In higher salinities (9, 12 & 15ppt) low fat and energy stored. The results suggest that Shyrbot fingerlings until 6ppt salinity can be easily developed.
