Islamic financial innovation: tools and trends / viewpoints by guest author Humayon A. Dar.
No full textIn a business context, innovation is of two types: model innovation and process innovation. Model innovation involves developing new instruments and methods (inputs) to achieve new objectives (outputs), which must bring new business and hence improve profitability. Process innovation is, in general, an incremental process that utilises existing instruments and methods in new formats and permutations to achieve desired objectives, goals and outcomes in a more efficient and cost effective way. In a business context, it will still be considered as an innovation if a desired outcome is achieved by utilising the same existing instruments and methods with no increased efficiency or cost effectiveness, as long as the new format and permutation result in increased profits
Optimizing Task Execution: The Impact of Dynamic Time Quantum and Priorities on Round Robin Scheduling
No full textTask scheduling algorithms are crucial for optimizing the utilization of computing resources. This work proposes a unique approach for improving task execution in real-time systems using an enhanced Round Robin scheduling algorithm variant incorporating dynamic time quantum and priority. The proposed algorithm adjusts the time slice allocated to each task based on execution time and priority, resulting in more efficient resource utilization. We also prioritize higher-priority tasks and execute them as soon as they arrive in the ready queue, ensuring the timely completion of critical tasks. We evaluate the performance of our algorithm using a set of real-world tasks and compare it with traditional Round Robin scheduling. The results show that our proposed approach significantly improves task execution time and resource utilization compared to conventional Round Robin scheduling. Our approach offers a promising solution for optimizing task execution in real-time systems. The combination of dynamic time quantum and priorities adds a unique element to the existing literature in this field
Wind Farms and Flexible Loads Contribution in Automatic Generation Control: An Extensive Review and Simulation
No full textWith the increasing integration of wind energy sources into conventional power systems, the demand for reserve power has risen due to associated forecasting errors. Consequently, developing innovative operating strategies for automatic generation control (AGC) has become crucial. These strategies ensure a real-time balance between load and generation while minimizing the reliance on operating reserves from conventional power plant units. Wind farms exhibit a strong interest in participating in AGC operations, especially when AGC is organized into different regulation areas encompassing various generation units. Further, the integration of flexible loads, such as electric vehicles and thermostatically controlled loads, is considered indispensable in modern power systems, which can have the capability to offer ancillary services to the grid through the AGC systems. This study initially presents the fundamental concepts of wind power plants and flexible load units, highlighting their significant contribution to load frequency control (LFC) as an important aspect of AGC. Subsequently, a real-time dynamic dispatch strategy for the AGC model is proposed, integrating reserve power from wind farms and flexible load units. For simulations, a future Pakistan power system model is developed using Dig SILENT Power Factory software (2020 SP3), and the obtained results are presented. The results demonstrate that wind farms and flexible loads can effectively contribute to power-balancing operations. However, given its cost-effectiveness, wind power should be operated at maximum capacity and only be utilized when there is a need to reduce power generation. Additionally, integrating reserves from these sources ensures power system security, reduces dependence on conventional sources, and enhances economic efficiency

Technological impact on the art of moviemaking: deploying new and convergent media to redefine a model for Pakistan’s cinema
No full textThis thesis examines the decline in Pakistani cinema during the last two decades. It examines the history of the cinema and exposes some possible, previously ignored, causes for that decline. This research led the author to ask “Can new and convergent media be helpful in reviving the Pakistani cinema?” The thesis introduces the ideas of established and emergent cinema, building on the work of Williams (1977) in discussing the ideas of dominant, residual and emergent culture. The exploration reveals two gaps in the film industry: first, the lack of training in the making of films; and, second, the change in possible production methods allowed by new and emergent technologies. The thesis addresses both of these gaps by suggesting new production paradigms which incorporate the new technology and by examining two scripts to develop methodologies for teaching. The scripts are produced into films as the practice section of the research. The first film, creative element 1, is developed using some of the new tehnologies, students as crew and the available resources of an educational establishment to test the methodologies that have been derived. The outcomes of the creative element 1 laid the foundation of the second film, creative element 2. It is shot on mobile phones and distributed from Pakistan through Vimeo with a negligible budget. The social networks helped to arrange equipment and locations and allowed extreme freedom to the filmmaker
