The purpose of this study is to fully evaluate a short range IEEE 802.11g channel at 2.4 GHz frequency by dynamic linking Ansys HFSS, a full wave electromagnet tool, and Ansys Designer, a system leveldesign simulator.The study presented in paper shows the integration of a 3D field solver and a circuit solver that enables the calculation of radiation patterns, electric field plots, bit error rate, constellation plots while incorporates the actual transmitter and receiver antennas and devices as well as TX/RX system with numerous modulation schemes. Multipath effects are also considered because the entire physical environment is modeled. Frequency and time domain responses are seamlessly combined in order to yield a complete response of the entire system. The scenario of the WiFi network is a room comprised of a router, a notebook and a phone. The concepts shown in this paper can be applied to Zigbee, Bluetooth, WiMax and many other wireless network types.

Agriculture is primary occupation in India and largely depends on ground water because of unscheduled canals, lowrain fall etc., Electrical Energy consumption for agricultural purpose has a major share in national energy consumption. Even though several methods have been followed from the past to lift ground water, pumps operated by electrical motors occupy larger percentage. Thus availability of electricity and availability of ground water became two vital elements for flourishment of agriculture and country to prosper. Operating hours of pumpset for various crops depends on amount of water required for the crop. In a crop cycle, for proper crop growth several irrigation cycles need to be scheduled. As there is direct dependence on electricity with water required for crops, estimation of energy consumed based on water required will definitely be an imperative task of interest. There is always a chance to show a high value for energy consumed by agricultural sector, which is not metered in Andhra Pradesh. In this paper, energy consumed for various crops is estimated in six districts of Andhra Pradesh covered by Andhra Pradesh Southern Power Distribution Company Limited (APSPDCL). This method may be useful in arriving at most reliable estimates for the energy consumed in agriculture.

A nation’s financial system is much more than just an intermediary that ensures the allocation of savings to investment. The efficiency of such a system is endogenously achieved if the financial structure of that economy promotes optimal use of the resources available for development. It is against the importance of finance in enhancing economic growth and development especially in developing economies like Nigeria, that we questioned whether financial structure has positive and significant impact on economic growth and development in Nigeria. The results revealed from our findings support existing literature that total financial structure has positive and significant impact on economic growth. However, while some sectors exert more influence (banking and market), other sectors (such as insurance) were found to have non-significant impact on economic growth. We therefore recommend that greater efforts should be made by govern-ment and the regulatory authorities at ensuring that an enabling environment is provided (through strengthening of existing laws and regulations) where all the components of the financial sector can compete favorably.

This paper is devoted to make use of the boundary element method as a practical problem solving tool to analyze the soilpile interaction problems. A computer program was adopted for the analysis process. It is a computer package called PGroupN which is concerned mainly with the analysis of the pile group problems. A non-linear soil model has been adopted with this program to assess the pile-soil interaction within the group. Some parametric studies were carried out with this problem including the pile diameter, pile length, spacing to diameter ratio, soil type (sand) and the thickness of stratum. It was found that for 9 pile group analyzed, the corner pile carries about 4% more than the average load, while the border and the center piles carry 2% and 10% less than the average load, respectively. As the ratio of pile spacing to diameter (S/D) increases, the difference between loads on each pile decreases, especially between the corner and the center piles

Microarray datasets enables the analysis of expression of thousands of genes across hundreds of samples. Usually classifiers do not perform well for large number of features (genes) as is the case of microarray datasets. That is why a small number of informative and discriminative features are always desirable for efficient classification. Many existing feature selection approaches have been proposed which attempts sample classification based on the analysis of gene expression values. In this paper a linear regression based feature selection algorithm for two class microarray datasets has been developed which divides the training dataset into two subtypes based on the class information. Using one of the classes as the base condition, a linear regression based model is developed. Using this regression model the divergence of each gene across the two classes are calculated and thus genes with higher divergence values are selected as important features from the second subtype of the training data. The classification performance of the proposed approach is evaluated with SVM, Random Forest and AdaBoost classifiers. Results show that the proposed approach provides better accuracy values compared to other existing approaches i.e. ReliefF, CFS, decision tree based attribute selector and attribute selection using correlation analysis.

Marriage as an institution in India has strong spiritual connotations. It goes beyond the mere satisfaction of physical desires-one of the four goals of human life i.e. Dharma (conducting one’s duty with compassion and righteousness), Artha (earning money), Kama (satisfying physical desires) and Moksha (liberation). These goals have been sanctioned by the Hindu scriptures which complete the cycle of life. The present generation in India and elsewhere has indulged in pursuing Artha and Kama so much, that they seem to have neglected the other main two goals of life-Dharma and Moksha. It is by incorporating these into life that the Kama may be meaningful. The present paper explores the religious connotation of the term ‘Kama’ in Hinduism keeping in view Maharshi Ramana’s poetry. It considers the metaphor of marriage in a spiritual sense and relates the usage of this metaphor to other poets in Indian religious tradition. It is in this perspective that metaphor of marriage is to be seen portraying the higher concept of union of soul-bride and God- bridegroom.

P2P network have dramatically gain popularity for the past few years. However, these networks suffer from problem like free-riding, Tragedy of Common which degrades the performance of the network. Here, the authors present several approaches to overcome the problem of free-riding. They have categorized the approaches and have described each category’s important features and implementations.

This paper studied the application of logit regression analysis to homeownership in Ado-Ekiti area of Ekiti State (Nigeria). The performance of the logit model in terms of classification of homeowners with respect to the average monthly income of some individuals was examined. The data of homeownership and income was fitted to the model by the WLS techniques. Result showed that the odds ratio in favour of owning a house by an individual whose average monthly income is 0.158 (N Million) was 1.0387. Also the probability of owning a house by the individual was 0.51.

The present study aims at analyzing whether there is significant difference in brands preference among five main brands of talcum powder used by the customers of the four major cities of the state of Uttar Pradesh in India. In this study a set of its 240 sales samples each in every city under study was examined through the retailers and found to be allocated among four communities i.e. Hindus, Muslims, Sikhs and Christians. Brand preferences are usually studied by attempting to profile and understand loyal consumers. The five brands under study are as follows: - Ponds, Lakme, Fa, Wild stone, Cinthol.
