Comparative Analysis of Spatio and Viterbi Encoding and Decoding Techniques in Hardware Description Language

The paper focuses on the design and synthesis of hardware chip for Spatio and Viterbi encoding and decoding techniques. Both techniques are used for digital data encoding and decoding in transmitter and receiver respectively. These techniques are used for error control coding found in convolution codes. Spatio coding is also used to eliminate crosstalk among interconnect wires, thereby reducing delay. The encoded data is in packet form may be of 2018;N2019; bits. Data is decoded at different clock pluses at which it is encoded. A comparative analysis is done for hardware parameter, timing parameters and device utilization. Design is implemented in Xilinx 14.2 VHDL software, and functional simulation was carried out in Modelsim 10.1 b, student edition. Hardware parameters such as size cost and timings are extracted from the design code

Phyto-synthesis of silver nanoparticles from Plumeria pudica leaf extract and its application in anti-cancerous activity

AbstractIn this study, we have developed an environment friendly and novel approach for the synthesis of silver nanoparticles utilising plumeria pudica leaf extract. In this technique, the leaf extract was employed as both a reducing agent for the reduction of a silver nitrate (AgNO3) solution and a capping agent, leading to the synthesis of silver nanoparticles (Ag NPs). The outcomes of these analyses revealed an average particle size of ∼19 nm as determined by SEM, while XRD measurements indicated a crystalline domain size of ∼12 nm and a lattice parameter of approximately 4.087467 Å. Furthermore, the anti-cancer potential of the synthesised silver nanoparticles was evaluated, unveiling an IC50 value of around 28 µM. This suggests that the introduced silver nanoparticles may have triggered apoptosis, consequently inducing cell death. These findings underscore the potential of utilising environmentally benign silver nanoparticles in lung cancer chemotherapy
