Abstract: The current scenario of Pakistan’s power sector stipulates the financial and technical viability of the utility companies to meet the escalating demands for electricity. Financial resources are required for the generation of electricity; which Pakistan cannot afford in the present situation. Pakistan have a huge potential for renewable energy resources; different areas across the country have a good irradiation value of solar energy. Through distributed generation arrangement, electricity can be generated near the consumer, e.g., a solar panel array or a small wind turbine, so that line losses of the distribution system decrease and voltage drop can be improved, and customers can also benefit through investing in DGs. This research aims at a comprehensive investigation of 07 High loss and tube well-dominated rural distribution feeders emanating from 132 KV Zafarwal Grid Station in Zafarwal, so that 1 MW Solar Distributed Generation study can be implemented for its impact on the high voltage Grid Station and optimization using the latest software tools like Arc GIS for geo database and GPS device for collection of real-time data from the field and Synergee Electric Software for load flow studies for PV and further optimization in the distribution network. The results of this research show that the optimal placement of solar PV on distribution lines introduces a power source near the load center, resulting in a reduction of voltage drop up to 3.5% and 35.21 % reduction in line losses. This decrease in voltage drop will lead to an improvement in power quality for users. It is recommended that before going to increase the level of distributed generation in the system a standard procedure should be developed, and it must be ensured that the inverter used by various consumers should not be allowed beyond a certain level of Harmonic contribution….

Abstract: The use of artificial intelligence in clinical trials opens the way for a period of transformation in which the potential to enhance efficiency, precision, and scope in clinical investigation is enormous. In this perspective, the promise and perils of AI regarding clinical trials are critically reviewed. On one hand, it’s where AI can really make some revolutionary changes to the most critical aspects of trial design and execution—like patient recruitment, data management, and predictive analytics—which are now adaptive and more driven by data; on the other hand, AI applied in clinical trials also brings considerable problems related to data integrity, ethical considerations, and regulatory compliance. Such potential of AI to further biases, break patient confidences, and exacerbate already wide inequities in healthcare raises the need for vigilant oversight. As AI is rapidly evolving, so too are principles that guide transparency, fairness, and ethical rigors that guide their application in clinical trials. This work presents a case for strong AI frameworks that are subject to firm validation and ethical scrutiny, which will ensure that the benefits of AI are realized with reduced risks associated with it. If the field goes down this road, AI integration in clinical trials is going to be the real catalyst for innovation, which could translate into achieving better patient outcomes and expanding frontiers for medical science….
