Future volatility forecasting intrigues many scholars, researchers, and people from the financial markets. The model and methodology used for forecasting are fundamental for asset pricing in general, since future volatility deeply influences the final result. Thus, this study uses databases from the companies Vale and Petrobrás, in the period from July 1994 to August 2013, to test the Univariate, Bivariate, GARCH, and EGARCH models (also analyzing the results for the linear and quadratic methods) in order to assess the best model for forecasting future volatility. The results indicate that the quadratic method can better forecast future volatility than the linear method. The Univariate model showed the best results, proving that it is more efficient to use only short-term volatility for future volatility forecasting. If it were necessary to include long-term volatility, the Bivariate model would be the best, despite the GARCH and EGARCH models showing similar results.

In recent years network security has become an important issue. Encryption has come up as a solution, and plays an important role in information security system. Many techniques are needed to protect the shared data. The present work focus on cryptography to secure the data while transmitting in the network. Firstly the data which is to be transmitted from sender to receiver in the network must be encrypted using the encryption algorithm in cryptography. Secondly, by using decryption technique the receiver can view the original data. In this paper we implemented three encrypt techniques like AES, DES and RSA algorithms and compared their performance of encrypt techniques based on the analysis of its stimulated time at the time of encryption and decryption. Experiments results are given to analyses the effectiveness of each algorithm.

Slums are known as culture of poverty. Thus there is lack of proper shelter, lack of basic requirements such as clean air, clean water, suitable toilets, and electricity. Lack of proper diet affects many, especially the growing children, lack of medical facilities result in spread of diseases, leading to ill health and loss of man-powers, lack of transport results in longer commuting times and longer hours to reach essential destinations. The concept of a slum varies widely from country to country and depends on a variety of defining parameters. Sometimes slums are used interchangeably with squatters. In general, it is considered as a residential area in urban vicinity inhabited by the very deprived who have no access to tenured land of their own, and hence ‘squat’ on vacant land, either private or public. For the thousands of poor in developing areas in India, especially urban areas have always been a means for improving their quality of life and environment, besides getting superior jobs and incomes. This, in contrast to deteriorating situation in the countryside areas has generated a substantial flow of migrants to cities, mainly in the last three decades. Priorities of urban migrants transform over time, depending on different conditions that they find themselves. The Raipur city is projecting immense development with sky scrapers, fancy flyovers, massive shopping malls and multiplexes. But what are co-existing are poverty, poverty of employment, poverty of shelter, poverty of basic necessities and poverty of access to basic infrastructure like electricity, water, drainage and sanitation. Housing for the poor is so scarce and consequently slums are mushrooming everywhere, with little action on the part of the authorities to ensure cheap housing for the poor. The so called slum rehabilitation authority does precious little by way of locating suitable land and constructing tenements with basic necessities. Poverty can be seen in the form of slum.

Flemingia macrophylla (Willd) Merril is a perennial leguminous shrub with higher potential of fodder use. The objective of the study was to identify its appropriate planting density,defoliation management, and fertilizer doses to the mature stands. The planting density experiment consisted of five treatments of different planting densities (15873, 18518, 22222, 27777 and 37037 plants ha-1) with four replications in a Randomized Complete Block Design (RCBD). Similarly, the defoliation management experiment was conducted in a 2x3 factorial combination using RCBD. The combinations of different levels of two factors; defoliation frequency (8 and 12 weeks interval) and defoliation intensity (0.25, 0.50 and 0.75 m defoliation height above the ground level), were used as treatments and replicated five times. Subsequent experiment was conducted on the three-year old mature stands of F. macrophylla for testing the treatments of five graded levels of phosphorus (P), viz. 0, 10, 30, 50 and 70 kg ha-1. Each level of P was combined with 30 kg N ha-1. The experiment was conducted in RCBD with four replications.

FDI is considered as an important tool for economic development of developing country. The term foreign direct investment is considered as one of the important contributors for the economic development of a country in particular and the world in general with the concept of globalization. Foreign direct investment has great impact on the development of developing country like Bangladesh. Foreign Direct Investment increases trade and investment, labor mobility, capital inflow, technology and know-how to the recipient country. The secondary data has been analyzed using tabular and graphical tools. Governments have now changed their policies from restricting towards promoting foreign investment. Though the government of Bangladesh provides fiscal, financial and other incentives, the actual flow of FDI is below the desired level.

Kinetics of Cyclization of propylene glycol and ethylene diamine to 2-methyl pyrazine has been studied over alumina-supported nanocrystalline MnFe2O4 catalyst in a differential flow fixed bed reactor in the temperature range 473 – 573 K. The partial pressures of propylene glycol and ethylene diamine were varied and rates were measured for the formation of 2 Methyl Pyrazine. Product selectivity as well as rate of formation of 2-methyl pyrazine was influenced by partial pressure of reactants. The rate equation R = k KP.KE PP PE / (1+ K P PP+K E PE )2 deduced, on the basis of adsorption of PG and ED in gas phase represented the data most satisfactorily.

The structural and catalytic properties of the mixed spinel ferrite system Mn1-xCuxFe2O4 (x=0, 0.25, 0.5,0.75, 1.0) have been investigated by X-Ray diffraction, Mössbauer and catalytic activity measurements.The variation of lattice parameter, crystallite size, and Mössbauer parameters of the product formed with the variation in the concentration of Cu has been studied.XRD Study revealed the formation of phase pure spinels with FCC cubic structure with particle size ranging from 5.21 nm to 20 nm. Lattice constant values showed constant decrease with increasing concentration.Mössbauer spectra showed the presence of Fe3+ at both octahedral and tetrahedral sites.These ferrites were used as catalysts in the alkylation of Aniline.A maximum conversion of 80.5 % of aniline with selectivity of 98.6 % towards N-methylaniline (NMA) has been obtained at a temperature 673 K, Methanol : Aniline molar ratio of 5:1 and weight hour space velocity (WHSV) of 0.2 h-1.It was found that the yield is maximum for CuFe2O4.The result is supported by acidity measurements.

Now a day’s parallel string matching problem is attracted by so many researchers because of the importance in information retrieval systems. While it is very easily stated and many of the simple algorithms perform very well in practice, numerous works have been published on the subject and research is still very active. In this paper we propose a omega parallel computing model for parallel string matching. Experimental results show that, on a multi-processor system, the omega model implementation of the proposed parallel string matching algorithm can reduce string matching time by more than 40%.

Antígona é uma obra cuja análise e discussão foi amplamente difundida. Entretanto trata-se de uma tragédia cujo conteúdo é profícuo e até esgotá-lo é um longo caminho. Sem negligenciar as várias pesquisas, ainda que nos mais diversos campos, no que concerne à Antígona, intenta-se repensar a posição dessa personagem em relação a seu tempo. Avaliar a força motriz que impulsionou seus atos e a fez tomar atitudes drásticas e, nesse contexto, localizá-la enquanto heroína ou vítima. Este trabalho objetiva fazer uma análise da tragédia grega Antígona, de Sófocles, sob a ótica da Psicanálise de Lacan para buscar compreender em que categoria a personagem se enquadra. Para tanto lançou-se mão de uma pesquisa bibliográfica cujos autores privilegiaram, de alguma maneira, a obra analisada. A fundamentação teórica versa em autores como Miriam Chnaiderman, Rachel Gazolla, Jacques Lacan, Evair Aparecida Marques, Kathrin H. Rosenfield, Sòfocles e Adalberto de Oliveira Souza. Fez-se uso de referenciais teóricos fundamentados em teorias psicanalíticas. O que foi possível observar em Antígona é uma consciente transgressão dos limites humanos. O Desejo de enterrar seu irmão Polinices representa o bem maior, o que é correto a fazer, a certeza de uma morte que não será em vão. Ela, então, age movida por esse desejo cujo objetivo primeiro é fazer o bem pela família, em nome do Oikos, a lei divina.

This study is done to examine the perceived service quality and purchasing aspects in various retail stores. This study becomes an important study as it helps in examining the differences among many variables of perceived service quality and purchasing aspects in retailing across the various demographic profiles. This study was carried out in three states. These three states are Delhi, Haryana (Gurgaon & Faridabad) and U.P. (Noida & Ghaziabad). A total sample size of 600 customers was chosen from seven organized stores in these three states. Finally 540 responses were received from these states. It gave a response rate of 90% in total. The data was analyzed with the help of proper statistical tools like descriptive statistics, Mean and Kruskal-Wallis test with One Way ANOVA was used. This test is applied as it is a non-parametric test and it is very helpful in finding out the difference among the different variables of Retail Service Quality Scale being used in this study. The scale used in this study was developed by Dhabolkar, Thorpe and Rentz. This scale was tested through reliability and validity first and then it was being used in the study to check out the significance difference among the different variables. The findings of the study state that there exists a significant difference among many variables across the various demographic profiles in the study. Finally implications for the managers are formulated in the study.
