A Novel Security Enhanced Decoder Based on XOR Detection for Optical Code Division Multiple Access System Using Multi-Diagonal Code

Abstract: Objective: The main aim of this research paper is to design a security enhanced decoder based on the XOR logic gate detection technique. Methods/Statistical Analysis: An all optical XOR gate has been designed by using Semiconductor Optical Amplifier (SOA) for the secure transmission in Optical code division multiple access system. Multi Diagonal (MD) code is implemented with all optical logical gate detection using non-linear effects in semiconductor optical amplifiers. To realize the XOR gate, two identical SOAs in MZI structure have been used. Finding: The Non-Return-to-Zero (NRZ) and RZ bit format have been compared and results show that using NRZ bit format the performance is better than RZ bit format and its optimum power comes out to be 0.6mW. A new design of Multi-diagonal code has been proposed by using all optical logical gate detection considering nonlinear effects in SOA. The design has successfully worked at Bit Error Rate (BER) 8.77×10 -09 . Application/Improvements: This design having decoder based on XOR logic gate utilizing the Multi-diagonal code will have wide applications in military for the secure transmission of data.

Efficient Hydrolysis of Lignocellulosic Biomass: Potential Challenges and Future Perspectives for Biorefineries

Abstract: Dwindling of petroleum-based fuels together with their frightening environmental effects has enforced the emergence of lignocellulose-based biorefineries Being most abundant and bio-renewable, lignocellulosic biomass holds enormous potential for production of biofuels, bio-based chemicals and materials for a sustainable energy future Utilization of lignocellulosic materials in a biorefinery requires a well-designed pre-treatment technology with reasonable processing cost for deconstruction of the lignocellulose complex Current technologies rely on chemical, physico-chemical and biochemical conversion routes for effective hydrolysis of lignocellulosic materials Identification of novel enzymes and microbes to counteract the pre-treatment-induced inhibitory products is a prime area of research as chemical detoxification method carries financial constrains Valorization of biomass is greatly influenced by generation of co-products in biorefining processes and their selective recovery, which may considerably reduce the cost involved in biofuel production The lab-to-industry transition of a bioprocess technology necessitates a sound techno-economical evaluation for optimum product yield to hit the market place

Robotics and Automation in Textile Industry

Abstract: For Many years, the application of automation has resulted in significant benefits to industrial world. High levels of consistency and precision in work pieces and high levels of repeatability and accuracy in manufacturing equipment have been required. Economic Justification can be shown only for large quantities of production. To achieve this, we need adaptive manipulation systems having some robotics mechanisms. Robotics is no longer a restricted field; it is a universal subject! As a result, the application of robotics in the industrial world as well as the textile industry has resulted in significant benefits. Application of robotics in textile industry is directed at minimizing human efforts in labour-intensive processes. Today automation in textile industry is often to be synonymous with Robotics. Since computer plays a key role in robotics, the word robot has a specific meaning and it has an emphasis in industry specially related to textiles.
