Viterbi decoder is working in wireless communications to decode the convolutional codes; those codes are used in every robust digital communication system. Such decoders are complex and waste large amount of power. In software defined radio receiver, field programmable gate array is considered as a highly configure option for software defined radio receiver is described using verilog code in Xilinx software. In this paper, used modification viterbi decoder for this reason reduced power and reduces number of slices, ACS, flip flops that can be implemented on FPGA. In this paper, a low power, adaptive viterbi decoder for SDR receiver is described using a verilog code and used constraint length is 9. The proposed design is implemented on Xilinx Spartan 3e.

Concrete, a homogeneous mixture of cement, fine aggregate, coarse aggregate and water is widely been used in construction activities. But cement and fine aggregate are becoming consequently costlier and their demand also increases every day. Meanwhile, industrial waste from manufacturing units also increases. On behalf ofutilization of industrial waste as well to minimize the construction material cost, some materials can replace the by-product of concrete. In this study we have chosen ceramic powder and copper slag as a replacement of cement and fine aggregate. More studies were carried out replacing cement but ceramic powder and replacing fine aggregate by copper slag separately. From the literature review we can to know maximum percentage of replacement of ingredients. In this study, different mix proportions were carried out by replacing different percentage of ceramic powder and copper slag. From the experimental results, it was observed that compressive strength was increased about 36%, when compared to conventional concrete.Keywords

Glory lily (Gloriosa superba L.) is one of the major medicinal plants of India cultivated for its seeds which are exported to developed countries for pharmaceutical use. Identifying germplasm is an important component for efficient and effective management of plant genetic resources. Variability for qualitative and quantitative traits was investigated in 18 genotypes of G. superba collected from different regions of Tamil Nadu and Andhra Pradesh. For qualitative traits, these genotypes were subjected to diversity analysis based on NBPGR descriptors. Fourteen qualitative and twenty quantitative traits of G. superba were evaluated to assess morphological variations among the genotypes collected. In qualitative traits, a large number of genotypes of the 18 clustered together, at 77% similarity in two clusters. Dendrogram constructed on the basis of twenty quantitative traits for the same set of genotypes did not reveal any clear pattern in grouping, and the genotypes were grouped into seven different clusters. Cluster analysis based on qualitative and quantitative traits revealed a different group of genotypes for each of the data-set. This clearly indicated that less variation existed between genotypes with respect to morphological traits. These easily observable morphological traits are useful tools for preliminary evaluation, because, they offer a fast and reliable approach for assessing extent of diversity in G. superba genotypes.Keywords

Phyllanthus amarus Schum. and Thonn (Euphorbiaceae) is recognized commonly as 'Bhumyamlaki' in the Indian system of medicine and has been traditionally used for treating a variety of ailments, including hepatic disorders. Anti-hepatic viral compounds such as phyllanthin and hypophyllanthin were evaluated in different types of in vitro cultures of Phyllanthus amarus by High Performance Liquid Chromatography (HPLC). Among the cultures, in vitro plantlets regenerating from the nodal segment recorded higher amounts of phyllanthin and hypophyllanthin.Keywords

Turmeric occupies about 6 per cent of the total area under spices and condiments in India. It is a long duration crop and the initial growth of turmeric is rather slow and takes about 4-5 months to cover the interspace. Therefore, the available space between the rows of turmeric could be effectively utilized by growing short duration crops like, vegetables, cereals etc. Hence, it is worthwhile to explore the possibilities of growing compatible crops with turmeric. With this background, this research project was formulated to find out the best compatible intercrop with turmeric, to study the effect of intercrops on growth and yield of turmeric and to determine the economic feasibility of turmeric based intercropping. In a nutshell, taking into consideration of the performance of various treatments in this experiment, it can be concluded that growing onion as an intercrop was found to be the best with respect to turmeric growth characters like plant height, number of leaves per plant, leaf length and leaf breadth. Although intercropping turmeric with cowpea is found compatible with maximum fresh turmeric rhizome yield per hectare (31.03 t/ha), the maximum B : C ration (2.53:1) was registered by turmeric intercropped with okra followed by turmeric + chilli (2.51:1). The monocropping of turmeric recorded the lowest B:C ration (1.70:1) among all the treatments.Keywords

Turmeric (Curcuma longa L.) is an ancient spice, native of India and South East Asia used from antiquity as spice and a dye. It is commonly propagated through rhizomes. The availability of disease free quality planting material is scarce during the cropping season (June – September). An experiment was conducted to study the performance of in vitro derived turmeric plants with conventional rhizome under field condition. The results indicated that the tissue culture plants showed better performance over the conventional rhizome planting. Tissue culture plants grew vigorously and taller than conventional type. The highest yield potential was observed in tissue cultureplants (40.83 tons/ha) as compared to the conventional rhizome planting (30.14 tons/ha). The rhizome rot incidence was lower (3.87%) in tissue culture plants than rhizome-derived plants (25.58%). However, the agronomic traits observed during the present study in tissue culture plants are stable and rhizome harvested from tissue culture plants can be used as disease free planting materials for further planting.Keywords

In India, there is a sweeping shift away from the centralised, controlled, and regularised regime and toward a more liberalised, market-friendly economic structure. Revolutionary advances in science and technology, particularly in information technology, have effectively transformed the modern world into a global village, resulting in a remarkable transformation in the economic system. The study’s major goals were to look at how the stated elements influenced the organisation climate in selected sugar mills in Tamil Nadu from the perspective of the employees. The present study is based on a survey method and is pragmatic in character. Personnel form five sugar mills provided the primary data for this study. There is a link between employees’ job happiness and their age, educational qualifications, monthly wage, designation, length of employment, number of family members, and marital status at selected sugar mills in Tamil nandu. In the sense that it indicated the degree of satisfaction of selected sugar mill employees in Tamil Nadu, the study was a pleasant experience. It is critical to meet the demands of sugar mill workers in order to create a friendly culture and a seamless interaction between both the mills and the employees.Keywords
