    (UMT, Lahore, 2013) Rabiya Khan and Kamran All Khan
    This study aims at finding the viewership of TV dramas in Lahore, the capital city of the largest populated Punjab province of Pakistan The study is based on survey methodology and the data was collected through the questionnaire comprising 14 questions. A sample size of 100 respondents aged 20-50 was with equal representation of males and females from all walks of life was taken. The study found that the love affair dramas are highly popular among the TV dramas viewers, as compared to dramas based on social issues, home politics and comedy subjects.

    Microcontroller based intelligent hybrid energy source and grid integration
    (UMT, Lahore, 2013) Fahad Ali
    This research work presents a fuel cell/battery model based intelligent hybrid energy source connected with a micro grid, which would resolve power intermittency and variability issues. A hybrid energy source (HES) composed of more than one storage devices that when incorporated, overcome limitations in either and can supply both high power and energy densities. The model proposed in this research work is composed of a battery bank and a stack of fuel cells, controlled by a microcontroller (AVR). The AVR microcontroller senses the load properties and then operates the energy devices accordingly as per required demands of the load. The limitations like economics, fuel flexibility, efficiency & reliability can be handled by this hybrid energy source. Different topologies can be considered in the designing of a hybrid energy source. The proposed model is very smart in the monitoring and control of the quality and stability of power delivered. This proposed model is integrated with the electric grid, which controls the voltage and frequency, further smoothes the variability of the generated power. This model mainly consists of digital controller (AVR Microcontroller), DC/DC and DC/AC converters that efficiently manage the power flow to the both DC and AC sides. Simulation results are given to show the overall system performance including the power management of the system.
