Reversible logic design(RLD) is gaining great importance due to its low power consumption and less dissipation of heat, especially Reversible logic gates(RLG) are employed in quantum computing, optical computing and designing low power CMOS, etc. Reversible logic design reduces the number of garbage output and reduces the complexity of the circuit. Code converters are widely used in digital systems for enhancing security, reducing the number of hardware components, minimizing the level of switching activities which reduces the power consumption and improves the speed of operation. In this paper we have simulated the design of code converters like Binary code to Gray code, Gray code to Binary code, BCD code to Excess-3 code and Excess-3 code to BCD code by using Reversible logic gates.Keywords

White Matter Lesions are small areas of dead cells found in the parts of the brain. In general it is difficult for medical experts accurately quantify the WMLs due to decreased contrast between White Matter (WM) and Grey Matter (GM) in MRI brain images. The main aim is to detect the White Matter Lesions present in MRI brain images which may result in memory loss or even death. This can be done by Fuzzy C-means Clustering (FCM) algorithm which is less sensitive to noise present at output and it detects false lesions also. To overcome this and to make detection more accurate Particle Swarm Optimization algorithm is used. PSO yields high sensitivity, specificity and overall accuracy over FCM.

The scientific and technological advantages o f nanostructured particles and materials have been attracting considerable attention. The main objective of this work is to synthesis titanium (Ti) nano particles by using the ball milling process and to characterize them. Titanium powder of initial size 4μm was milled for 40 hours. At the end o f 20 hours, it was observed that the agglomerated nanoparticles size varied from 200nm to 326nm. At the end o f 30 hours, it was observed that the agglomerated nano particles size varied from 90nm to 140nm. At the end of 35 hours, it was observed that the particles were o f nano particles size whose range was 84nm to 119nm. At the end of 40hours it was observed that the particles were of nano size whose range was 66nm to 120nm. The Ti nano particles produced were characterized by Wide Angle X-ray Diffraction (WAXD), Energy Dispersive X-ray Analysis(EDXA) and SEM analysis techniques and the images of the same were obtained.- Power Quality Improvement in Power System Using Multilevel Inverter under Non Linear Load Condition

The multilevel inverter reduces the harmonic contents and achieves sinusoidal signals. The hybrid active filter to achieve power quality compensation and active power filter with low power rating is used to filter the other higher order harmonics and power factor can also be improved. Almost near to unity with the help of shunt capacitors this system helps to improve the electrical supply quality. A Multilevel Inverter (MLI) is a power electronic device built to produce a desired A.C voltage from several levels of DC voltages.
Generally unbalanced voltages will occur at supply side these can be eliminated by using multi-level Inverter. Hence increase the efficiency of the system if the system stability problems or power quality issues which needs to be resolved and limited utilization and they operate at relatively low power level with respect to the designed power rating during most of long-term field operations High temperature peaks and variations on switching devices due to the intermittency which accelerates the degradation of the switching devices. To tackle the overloading issue, this system therefore proposes a hybrid power control concept with the objective to improve the system performance and increase the power factor of multilevel inverter and hence MATLAB simulation have been carried out.

Indian spices are known for their aroma and flavour widely rigorous in the international and domestic market. The Black pepper “King of Spices” and Cardamom (small) “Queen of Spices” are predominantly grown in the regions of Chikmangalore, Shimoga, Idukki and Ernakulam, the former two of state Karnataka and latter to Kerala. These selected spices supply chain differs from other agricultural commodities due to long gestation period and small, marginal growers. Thus, black pepper and Cardamom are considered to be the potential spices for value addition. It holds a huge export potential than the traditional raw spice export. A study was conducted to assess the consumer preference towards various attributes in quality of spices was studied by confronting attributes like prices, usage of branded spices, switching pattern from branded spices to other and willing to pay more to get the desired quality were analyses using SPSS software. Among the selected districts, 34.75 per cent of consumers are brand conscious, specifically Chikmangalore shows the highest preference for branded spices. Hence, this district was found suitable for marketing of value added spices.Keywords
