Remotely-sensed data obtained from satellites or aircraft are usually geometrically distorted due to the acquisition system and the movements of the platform. Preprocessing of satellite images prior to image classification and change detection is essential. Image Processing is a technique which is used to enhance raw images received from cameras and sensors placed on satellites, space probes and aircrafts or pictures taken in normal day-to-day life for various applications. Digital image processing is the technique of processing images in the form of discrete digital brightness quantities by means of using digital circuits or digital computers.

The purpose of present paper to study and introduces the concepts of fuzzy arw- super closed mappings and obtains some of their basic properties and characterizations in fuzzy topology.

This paper develops a heuristic algorithm for the multi-index fixed charge transportation problem. The efficiency of this algorithm for solving the multi-index fixed charge transportation problem has been proved by comparing the results obtained by using this algorithm with the existing exact method of solving multi-index fixed charge transportation problem. Further the proposed algorithm is extended to multi-index fixed charge fuzzy transportation problem in which all the parameters are considered as trapezoidal fuzzy numbers. A numerical example is presented to illustrate the proposed method.

Performance of a domestic split type air conditioner was evaluated by using two different refrigerants, i.e., R22 and R290. This paper presents the outcomes of this comparative study. The experimental investigation was conducted by using a 1 hp air conditioning unit. Power consumptions by the complete system including the evaporator as well the by the compressor alone were measured by clamp meter. Temperature was also measured at different locations by digital fluke thermometer whereas digital multimeter was used to measure the current supplied to the system. The air conditioner was run for six hours each time by setting three different set point temperatures, i.e., the cold air temperature coming out from the evaporator. From the measured information, coefficient of performance (COP), and energy efficiency ratio (ERR) were calculated for each refrigerant. The results revealed that R290 refrigerant has better COP and EER compared to R22 refrigerant. The usage of R290 refrigerant can reduce energy consumption up to 11 %. In addition to that, at the same air conditioning unit, the amount of R290 refrigerant required is relatively half of that required by R22 refrigerant.

It is significant that Karanta has made an effort to unravel the sensitivity of women's psychological pains in a way that the female can see her identity as a way of violence, oppression, helplessness. Her sacrifices, sacrifices, patience, tolerance and duty-keeping can be seen in the mind's eye, even in the shackles of female problems

Well-designed course assignments are a critical component of effective teaching and learning processes. It is our responsibility to create an assignment that is reflective of the course goal. Course assignments are created to measure the extent of our student’s knowledge. Therefore, based on our experience and knowledge, we have written below how at Mongolian University of Science and Technology the Profesional English course’s assignments should be created and carried out.

The present work envisages the synthesis of polyaniline and its doping with salt of a transition metal (Titanium) and effect of dopant on its optical properties to study changes in band gap. Polyaniline was synthesized by process of chemical oxidative polymerization. Chemical Doping of the dopant has been carried out in synthesized polyaniline by making different concentration of dopant in neutral medium and using THF as solvent. An effort has been done to see the effect of dopant in polyaniline by its properties characterized by UV-Visible spectroscopy and then determining band gap with the help of UV spectra.. A significant change has been observed after doping. UV-Visible study shows that optical parameters change after doping. The study reveals that strong dopant interaction takes place with polyaniline network which is responsible for observed changes.

We aimed to investigate factors associated with the creation of a learning organization at Shahid Beheshti University in Tehran through the perspective of faculty members of the university. research method is Descriptive- survey. Sample population in this research include faculty members of Shahid Beheshti University which 517 subjects were selected using multi-stages cluster sampling and the researcher questioner was delivered to the subjects. The question numbers were determined based on Morgan among 221 people. Data collected via questionnaire regularly. Questionnaire used in this study is feasibility of the approach and is based on the Likert scale ratings. Towards data analysis, descriptive and inferential statistical has been used. Descriptive statistical estimates the frequency distribution , percentage, density , mean , and .... . For hypothesis test, inferential statistical parameters such as Pearson correlation coefficient , ANOVA , t independent groups , multiple regression, post hoc Tukey test was used for data analysis . results showed that among the eight -component communication patterns , reward system , individual autonomy , risk - taking, conflict , identification, management support, coherence, integration and creating a learning organization at Shahid Beheshti University is a significant relationship between them which the description of each component of the items discussed during the study findings are presented.

The main aim of this study is analysis Employees’ involvement and quality improvement in Iranian small and medium enterprises (SMEs). This research is conducted based on descriptive and surveying method; to collect data, was chosen through questionnaire. For research’s purposes, a distinction was made between small firms (fewer than 50 employees) and medium-sized ones (between 50 and 250 employees), questionnaires was mailed to 600 Iranian SME randomly selected. The questionnaire was pre-tested and validated with the help of a panel of two academics/researchers on quality management issues and two quality managers in SME. Out of the sample, a total of 95 questionnaires were completed and returned. Data gathered through questionnaires were submitted to a set of statistical analyses tools, using SPSS (Statistical Package for Social Sciences), and punctually, some of Microsoft Excel’s statistics and data bases tools. In accordance with research purposes, univariate analyses were performed on issues strictly descriptive, while bivariate analysis tools were used on issues based on means comparison (Student’s T test and Chi-square test). Showed that in considered society, most SME developed training programs specifically focused on quality improvement, suggesting that, beyond fostering quality improvement awareness, SME supply their employees with tools necessary to develop their skills and(or acquire new insights needed to improve their performance. These evidences may indicate that top management is aware about the importance of training and development focused on quality improvement, for effective employees’ participation in quality continuous improvement initiatives.

Recent years, Light energy consumption minimization has become the important aspect. In this, it is proposed to develop a system that will help various organizations to play an effective role in saving electrical energy. Energy utilized for lighting purpose sums up to a considerable part in the overall energy consumed. Effective and efficient lighting helps in reducing the unwanted excessive use of energy wasted. Smart illuminance control techniques concentrates on providing effective illuminance at a work place by varying the dimming levels of the networked luminaires.so here we used arduino board and Light Dependent Resister sensor to control the room light. Keywords— Arduino, Light Dependent Resister
