Abstract– Today, intelligent buildings have received more attention, as well as, microgrids will have the significant role in future smart power distribution system. Smart building integrated with microgrid can provide much comfort, quality, safety and high energy efficiency for the users. Microgrids can integrate the conventional and renewable energy power generation systems, energy storage systems and controllable loads. Microgrid planning is a complex problem with technical, economic, and environmental attributes that should be considered. In this paper, Multi Criteria Decision Making (MCDM) approach is suggested for the selection among various microgrid planning options. Different plans are generated by various combinations of conventional and renewable energy resources. Five attributes namely, profits from injecting power into grid at peak load, capital costs, cost of energy (COE), total emissions, and energy not served are considered. The Analytical Hierarchy Process (AHP) method is used for weighting the importance of the different criteria, and MULTIMOORA method is proposed for prioritizing of different plans. The final ranking of the plans is obtained considering uncertainty in demand. Three loading conditions are considered as high, medium and low. The proposed procedure is applied to a sample system and numerical results are presented.

Abstract– Purpose: The purpose of this paper is to quantify the impact of office design and reward system on the performance and motivation of the employees in banks both public and private sector of Gujrat. Office design such as lightening, furniture, noise, temperature etc and both extrinsic and intrinsic rewards are affecting the motivational and performance of employees. Design / Methodology / Approach: For data collection questionnaire method will be used. Questionnaire will be distributed among the respondents from the selected banks and SPSS will be used for data processing finding correlation and multiple regression analysis. Findings-Research Limitations: This study was conducted in district Gujrat only so there are chances that result may vary while moving to other geographical locations. Gujrat district is basically a smaller location where background of mostly workers is not well developed so priorities related to work environment many vary for them so in generalizing the results to the whole country results may vary from one location to other. The purposed model can be used for further studies in different geological locations. Practical Implications: The result allows banks decision makers to develop strategies that can increase the motivation and performance of their employees which ultimately results in higher performance of the banks. Banks should follow on the internal design of their offices so that their employee’s productivity and motivation can be increased. Also pay attention to the reward system to increase performance and motivation. Originality/Value: The findings allow the factors that can influence the performance and motivation of employees while they are at work. Purposed model include all the possible variables that influence it. This can be adopted in other cities to check the same phenomenon.

Abstract– Multilevel queue scheduling and Real time scheduling is common in CPU scheduling techniques. In this paper different techniques for scheduling these algorithms has been collected and discussed. Primarily an introduction to multilevel queue and real time scheduling are discussed. In multi-level queue scheduling, the starvation problem has been solved efficiently but this technique is not suitable for real time processes. To overcome this problem, an idea of new algorithm i.e., MLQPTS (Multilevel Queue with Priority & Time Sharing Scheduling) have been proposed. In this algorithm, all the processes are listed in a queue and this queue is built depending upon the priority of each process. This priority is calculated by considering the factors such as waiting time, processing time, deadline time, etc of each process. A queue executes for a specific time called Queue Execution Time. Each process gets its time share in execution depending upon the priority-level. After each execution interval, priority of each process is re-calculated and a new queue is built which accommodates the new incoming process as well. In this way, our proposed algorithm has the properties of MLQS and it can also accommodate real time processes. The objective of the study is to have better understanding of Multi-Level Queue and Real time scheduling and to see what challenges they have to face and how these challenges are resolved by using different techniques.

Simulating Solar and Wind Based Hybrid Systems Synchronized and Segmented for Grid Connectivity

Md. Sifat Ferdous Chowdhury and Mohammad Abdul Mannan

Abstract– This paper introduces the performance of hybrid power system which has a combination of solar power and wind power. PV array is extracting maximum energy from sunlight irradiation by using Maximum Power Point Tracker; it collects the power from the system and sends power to the dummy utility grid. On the other hand, depending on the velocity of the wind available, wind turbine rotates and energizes an asynchronous generator for power supply to the grid. These two separate sources are connected together for hybrid operation and synchronized appropriately for segmented power supply to the grid. For visual retrieve ‘SimPowerSystem’ tool of MATLAB has been used for simulating the same.

Abstract– The purpose of this study is to identify the effect of work overload on Job Satisfaction and effect of job satisfaction on employee performance and employee engagement. Literature supported the relationship between work overload and Job satisfaction, the relationship of job satisfaction with employees performance and employee engagement. To measure this, data was collected with the help of questionnaires. The questionnaires distributed among the sample size of 207 employees of Public Sector University of Gujranwala Division including teaching faculty and non teaching staff. Data was analyzed by using SPSS software. This study revealed the relationship of work overload on job satisfaction of the employee which is most important thing of any organization. This study provided further guidance to organization for making strategies to cope with these prevailing. So this study is important to overcome the problem of work overload which affects the job satisfaction which ultimately affects employee performance and employee engagement.

Abstract– This study has been undertaken to find out the impact of work family conflict and family work conflict on job satisfaction and life satisfaction of University employees. To see the impact of work and family conflicts on job satisfaction and life satisfaction, the study was conducted in education sector of Pakistan i.e. Public Sector University of Gujranwala Division of Pakistan. The data was collected from 180 respondents from the public sector university through questionnaire. The data was analyzed using SPSS. The results supported past literature and revealed that relationship exists between work & family conflicts and life & job satisfaction. The results also explored the new dimension that strong positive relationship exists between work-family conflict and family-work conflict. Further it revealed that job satisfaction and life satisfaction of an employee get affected due to the imbalance between his/her work and non-work responsibilities.
