In general, existing cQA forums provide only textual answers, which are not informative enough for many questions. Conventional MMQA aims to seek multimedia answers without the assistance of textual answers. This MMQA scheme using diversification method is able to enrich textual answers in cQA with appropriate meta data which improves the informativeness and it bridges two gaps (i) The gap between questions and textual answers (ii) The gap between textual answer and multimedia answer. This scheme consists of three components: answer medium selection, query generation and data selection and presentation. This scheme determines the type of media information that can be added for a textual answer. This scheme predicts the type of medium to be added using Naïve Bayes Classifier, it automatically generates query based on QA knowledge and performs multimedia search. Finally this scheme performs query adaptive re-ranking and duplicate removal to obtain a set of images and videos for presentation along with textual answer. This scheme uses diversification methods to make the enriched media data more diverse. This scheme uses Page Ranking algorithm to retrieve more relevant and diverse search results.

Social security is an important political issue for any country that brings influential and profound political and legal impacts. Its most important political and legal impact is seen in emergencies when social administrators should manage a crisis in terms of their natural duty. To this end, they inevitably choose to limit their citizens’ personal rights. Since paving proper grounds to exercise personal rights, crisis management and national security are, inter alia, the functions of the governments and the guidelines to provide them are contradictory due to their natures, limiting the domination of personal rights is considered as one the most reasonable guidelines to curb existing problems in a political society. The important issue created by the scope of such limitation in personal rights that causes the biggest challenges to the legitimation of such guidelines during emergencies is the principle of no harm and forbidding harms to other people as a proper criterion for governmental discretion scope in exercising the rules of emergency time and in limiting personal rights.

One of the main problems in sampling survey is the optimal allocation of resources. The solution of this problem is rather arbitrary due to the fact that no best allocation is defined. In this model, the allocation problem was to find the allocation of a sample to strata which minimizes cost of investigation. The idea of optimal allocation under a multivariate stratified sampling based on an alternative approach earlier worked on by Diaz- Garcia and Ranos– Quiroga was applied. The matrix of the variance-covariances of the vector of the stratified variables was obtained. An emperical data from a household survey conducted in Ogun state was used. The frame consisted 880,970 households in the twenty local government areas (LGA) of Ogun state. Each of the 20 LGAs that made up the state was seen as a stratified cluster. Post stratification in this study ensured that some variables that are suitable for stratification was achieved after selection of the sample. The four characteristics of interest were occupation, income, household size and educational level. The study transformed all variables in the stratified sampling plan by using dummy variables ranging from 1-3. The estimates used in the computation were calculated using statistical software Splus. The post stratification estimator ?st does not have the same variance as the stratified sample mean. Stratification produced a gain in precision in the estimation of characteristics of the household survey. The results of the estimates in the study revealed that proportionate allocation can lead to smaller sampling variances than for simple random samples of the same size.

The objective of this paper is to explore perception among the pass out graduates of different universities regarding challenges faced by graduates’ business education in Pakistan. A total of 300 respondents were randomly selected from different universities of Pakistan giving a response rate of 83 percent. The selection was made through simple random sample. The data obtained through questionnaire. The result of this study revealed that most of the respondents are satisfied regarding major reason of joining MBA programme. MBA programme helps in career development, deliver managerial skills, provide good opportunity of employability. Above 70 percent respondents working in well reputed organizations at top and middle level management, rest of them at lower level and non-managerial and they have completed their degree in full time programme before joining organization. It was found also that they have good business insight and career development. Overall result shows that 80 percent respondents have achieved their goal and made improvement in career, work status and management abilities. The result shows that all skills important for employer but most important are managerial, conceptual and interpersonal skills that MBA programme must deliver.

Vibrational spectral analysis was carried out for 2-chloro-1-fluoro-4-nitrobenzene (CFNB) by using the FT-IR and FT-Raman spectroscopy in the range of 4000 cm-1 to 400 cm-1 and 4000 cm-1 to 100 cm-1 respectively. The theoretical computational density functional theory (DFT/B3LYP) was performed at 6-311+G** levels to derive equilibrium geometry, vibrational wavenumbers, infrared intensities and Raman scattering activities. The complete vibrational assignment was performed on the basis of the potential energy distribution (PED), calculated with scaled quantum mechanics (SQM) method. Natural bond orbital (NBO) analysis was applied to study stability of the molecule arising from charge delocalization. Quantum chemical parameters such as the highest occupied molecular orbital energy (HOMO), the lowest unoccupied molecular orbital energy (LUMO), energy gap (?E), were calculated.

The need to generate pollution free energy has triggered the effect towards the usage of wind energy interconnection with the grid. Thus, the wind power plants l interfaced with the grid causes the power quality problems such as a harmonics, voltage sag etc., Active power filters are the powerful tool for mitigation of harmonics. This proposed work describes the methodology for improving power quality of the grid system interfaced with renewable energy. The inverter used this methodology can also be used as a power converter for injecting power from RES to grid along with harmonic compensation. This concept is validated through dynamic simulation using MATLAB/Simulink Power system toolbox.

The aim of this study was to determine greenhouse gas (GHG) emissions and indicators for energy use and to evaluate energy sensitivity of seed and grain corn production in Pars Abad Moghan, Iran. The data was collected by a face-to-face interview method from 144 corn farms during 2011 year. Most of energy consumption in seed and grain corns was related to diesel fuel and chemical fertilizers. The net energy, energy productivity, energy intensity and GHG emission were -4688.77 MJ ha-1, 0.06 Kg MJ-1, 16.4 MJ Kg-1 and 1810.11 kg CO2eq ha-1 for seed corn and 58330.63, 0.18, 5.53 and 1490.13 kg CO2eq ha-1 for grain corn, respectively. The percentage share of renewable, nonrenewable, direct and indirect energies were 3, 97, 46 and 54 for seed corn, and 2, 98, 50 and 50 for grain corn, respectively. The highest value of GHG emission belonged to diesel fuel with share of 64.22% and 66.66 % of total emission for seed and grain corn, respectively. An econometric model was also developed to estimate the impact of energy inputs on yield by using Cobb-Douglas production function. For this purpose, seed and grain corn yields were assumed to be functions of energy inputs.

Present investigation deals with the assessment of fecundity of catfish Macrones vittatus (Bloch, 1794) collected from Bhategaon dam, Maharashtra during January to December 2011. The mean value of fecundity produced by an individual fish was found to vary between 2562 to 26316. In Macrones vittatus (Bloch, 1794) maximum number of eggs was observed in 162 mm in total length and 30065 mg in body weight, whereas, minimum was observed in 102 mm in total length and 9265 mg in body weight. The relationship of fecundity with other parameters such as Total length (TL), Total weight (TW), Ovary weight (OW) and Ovary length (OL) were found to be linear and non linear and the values of correlation coefficient (r) was 0.92, -0.11, 0.93 and 0.81.
