Objective: The interest concern towards the development of enabling technology towards new current mode devices has forced the designers and researchers for the invention of devices, which has having the characteristics like such as low power, robustness, compactness, efficiency and scalability. Methods: Second Generation Current Controlled Conveyor (CCCII) is the prevailing current mode device of the times today. Since its invention by A. Fabre, it has prominent applications in the field of analog signal processing and in biomedical applications too. In this manuscript, CCCII is used as an enabling device to design a Frequency Shift Keying (FSK) Generator. Results: The proposed topology is designed using a single active device CCCII with least passive components. The circuit enjoys the features of like electronic tunability of frequency using the bias current. Conclusion: It can be concluded that the FSK generator circuit designed using single CCCII confers better results in contrast to the existing structures. The maximum power consumption is 0.196 mW. The proposed circuit has the benefit of simple configuration, which is very much proficient for IC fabrication.

Linear Congruential

<p>This paper presents the Design and implementation into Field ProgrammableGate Array (FPGA) of a combine stream cipher and a simple linear congruential generator circuit to produce key stream. The LCG circuit is used to produce initialization vector (IV) each 2<sup>64</sup> clock cycle to the cipher trivium in other to strengthen the complexity of the cipher to known attacks on trivium. The LCGTrivium is designed to generate 2<sup>144</sup> bits of keystream from an 80-bits secret and a variable 80-bits initial value. To implement the LCG-Trivium on FPGA, we use VHDL to build a simple LCG and Trivium and a state machine to synchronize the functioning of the LCG and Trivium. The number of gates, memory and speed requirement on FPGA is giving after analysis. The design is simulated, synthesized and implemented in Quartus II 10.1, ModelSim-Altera 6.5 and Cyclone IV E EP4CE115F29C7N.</p>

In the present work the effect of the use of synthetic sound during incubation in chicken of the Hampshire breed was studied. For the stimulation, an electronic sound generator with amplitude of power 1250 mV and time interval of 134 ms, 176 ms, 210 ms and 380 ms was used. The study was carried out in three experiments. In the 1 st experiment we tried to determine the influence of sound stimulation on the hatching of chickens from egg set of the variant of weight. In the 2 nd experiment we tried to determine the influence of the variant of the beginning of sound stimulation on chicken hatching. In the 3 rd experiment we tried to determine the influence of sound stimulation with constant amplitude of power and the variant of the time interval on chicken hatching. The most suitable eggs to be used for the stimulation with synthetic sound are the ones with the weight of 58.0-60.0g. In this weight category, the chickens hatched earliest of all the groups and there was no decrease in hatchability either. In order to achieve an earlier beginning of beak clapping, a faster whole group beak clapping time, and a shorter hatching time of chickens, sound stimulation should begin at the 433 rd hour of hatching. At the constant amplitude of power of the stimulating sound, the earliest hatching was observed when the time interval was 176 ms. Less suitable for stimulation are the time intervals 134 ms and 380 ms.
