This study examines integration among Karachi Stock Exchange of Pakistan and Shanghai Stock Exchange of China. Monthly data ranging from January 2001 to December 2010 is included and tested in this paper. This relationship is tested by using descriptive statistics and correlation matrix. Data stationary is ensured by Unit Root Test. Evidence from Granger Causality and Impulse Response Test. The Results shows that SSE and KSE has no long term relationship or impact on each other focusing on the data of KSE (Karachi Stock Exchange) and SSE (Shanghai Stock Exchange).

The present study is an attempt to find out appropriate ARIMA model by using Box-Jenkins methodology to forecast the export/import of wood based panel in India on time series data for a period of 16 years from 1996-97 to 2011-12. Test criterion like lowest Bayesian Information Criterion (BIC), R2 value and lowest of mean absolute percentage error (MAPE) are applied to predict the accuracy of the model. This study found ARIMA (0,1,0) with R2: 0.83 for the export and ARIMA (0,1,1) with R2: 0.87 for the import to forecast of export/import of wood based panel. The estimated export and import of wood based panels in the year 2020 would be increased by 170% and 127% in respect to 2012.

Gesture Recognition plays a vital role in computer vision. The purpose of this survey is to provide a detailed overview and categories of current issues and trends. The recognition of human hand gesture movement can be performed at various levels of abstraction. Many applications and algorithms were discussed here with the explanation of system recognition framework. General overview of an action and its various applications were discussed in this paper. Most of the recognition system uses the data sets like KTH, Weizmann. Some other data sets were used by the action recognition system. In this paper, various approaches for image representation, feature extraction, activity detection and action recognition were also discussed.

Worldwide national policies on higher education are giving increasing importance to improve the quality of education on offer. Consequently, the evaluation of teachers’ performance is especially relevant for the academic institutions as it helps to define efficient plans to guarantee quality of teachers and the teaching learning process. However, a key challenge is to understand the complex range of features associated with teacher evaluation, the contentiuos issues on accuracy and reliability of classical evaluation methods coupled with both mixed empirical evidence about their effects on students’ learning and conflicts of interest between key actors of education systems. This paper is an overview of evaluation of teachers’ performance in higher institutions, challenges in the progress, the main research areas and its applications to develop an effective and improved teachers’ performance evaluation system.

Dilaceration can be seen in both the permanent and deciduous dentitions, and is more commonly found in posterior teeth. Periapical radiographs are the most appropriate way to diagnose the presence of root dilacerations. The controlled regularly tapered preparation of the curved canals is the ultimate challenge in endodontics. Careful and meticulous technique will yield a safe and sufficient enlargement of the curved canals. This article gives a two interesting case reports of root dilacerations and its management endodontically by using both hand and rotary instruments.

Risk assessment is an important and more popular aid in decision making process. Risk assessment is generally performed using models and model is a function of some parameters which are usually affected by uncertainty. Here, we consider that the model parameters are affected by epistemic uncertainty. To represent epistemic uncertainty generally triangular fuzzy numbers or trapezoidal fuzzy numbers are used. In this paper, Cauchy fuzzy number together with triangular fuzzy numbers is used to represent epistemic type uncertainty. An effort has been made to fuse Cauchy fuzzy number with triangular fuzzy number and then human health risk assessment is carried out under fuzzy environment.

Densities, viscosities and ultrasonic velocities have been measured for the binary mixtures of anisic aldehyde with methyl acetate, ethyl acetate and n- butyl acetate over the entire composition range at 303.15,308.15,313.15 and 318.15K .The excess values were correlated using Redlich – Kister polynomial equation. The excess values were examined in order to have an insight into the inter molecular interactions among the components of the binary mixtures that lead to the possible dipole- dipole interactions or hydrogen bond formation between unlike molecules. Excess molar volumes, deviation in adiabatic compressibilities, deviation in viscosity and excess free length are negative in the whole composition range for all the systems at all temperatures.

The developing countries mostly rely on traditional medicines. The traditional medicines involve the use of different plant extracts or the bioactive constituents. This type of studies provides health applications at affordable costs. Biochemical studies of the individual plant parts is a necessary prerequisite in order to evaluate their importance in the over all metabolism of the plant. In the present study various plant parts of selected medicinal plants were evaluated, separately for their metabolite content. Maximum amount of total soluble sugars and lipids were present in leaves of Rumex vesicarius, starch in stem of Sisymbrium irio. The leaves of Rumex vesicarius showed more content of metabolites as compared to the other plant parts.

In the changing world, today's complex and competitive, successful and effective organizations that can provide a variety of factors to create the demand, among the factors governing the ability of employees and corporate culture of an organization has a special place in Kermanshah. The data collection questionnaire to measure organizational culture, organizational culture Hafstd 43 items (1990) and to assess the ability of the questionnaire, 12 questions, capability Asprytzr (1996) is used. Hypothesis test to By Spearman correlation test were positive and significant relationship was demonstrated in total, meaning that the result-oriented and component principle easy to control the hardware capabilities.

A Novel type of analog divider is described. The circuit enables division of a dc voltage with another dc voltage. The constant of division is dependent upon two resistor values. Employing precision resistors, an acceptable level of accuracy can be obtained in the division. Verification of the feasibility of the circuit configurations are established by way of test results on a proto type.
