Abstract: Power factor (PF) is defined as the ratio of active power to apparent power, so the mount of the active power from the total apparent power depends on power factor. Electricity companies exerting big efforts to explore ways to reduce costs, and one area that is drawing interest is power factor improvement (PFI). This paper discusses the saving in money due to PFI for the consumers and the economical advantages for the electricity companies, as well as the factors affecting this, such as PFI methods, harmonics and billing practices of the electrical utility. Kassala distribution net-work is taken as case study. The saving in money and economical effect of PFI are determined. The results show the big saving in money and other economical benefits due to PCI.

Abstract: The sand mining industry plays a crucial role in supporting various sectors of the economy, but its sustainability and responsible management are essential to mitigate its environmental impact and ensure the long-term availability of this valuable resource. Consequently, many stakeholders, including governments, industry players, and environmental organizations, are working to find solutions to the challenges associated with sand mining. The demand for sand is driven by various industries, particularly construction, which uses sand in concrete and asphalt production. As urbanization and infrastructure development increase worldwide, the demand for sand has risen significantly. Sustainable sand mining practices aim to balance the need for sand with environmental protection. This involves responsible extraction, reclamation of mined areas, and reducing dependence on natural sand through recycling and alternative materials. In some areas, illegal sand mining is a significant problem. It often occurs in sensitive ecological areas and can lead to conflicts between illegal miners, local communities, and authorities.

Abstract: Free Space Optical (FSO) communications has regained a great interest over the last few year, where optical transmission line uses the optical fibers cables as medium but in free space optical link we us the space as the medium to transmit the optical signal. The transmission medium of free space optical is significantly affected by the various weather conditions such as rain, fog, snow, wind, etc.

The performance of FSO system has faced adverse consequences due to various changes in the properties of the channel such as weather conditions and length of the channel up to which the information needs to be transmitted. This paper, study quality factor (Q-factor) for using two types of modulation formats and compares their performance. Hence the performance was analyzed by the Q-factor with respect to varying distance, data rate.

Abstract: The huge demand of electrical energy is growing day by day. Conventional energy source which is produced by fossil fuel is not sufficient to fulfil the current demand of electrical energy and this is also exhaustive in nature. Now it is serious issue for energy researchers to find any alternate energy option. Solar energy is one of the most expanding renewable Energy. The performance of solar cells depends upon solar irradiance and its angle of incidence of light on PV panel. When the temperature varies, its power and effectiveness also vary. The aim of researchers is to find power and effectiveness should be optimum. Continuous incident of light at optimum angle of PV panel can be made possible by dual axis solar tracker. In this type of tracking system, there are two servo-motor used to move the panel vertical and horizontal axis. LDR is used to sense the light intensity and send the analog signal to the microcontroller and according to the signal, microcontroller move the solar panel using servo motor. This design provides the comparative study between the fixed axis solar panel and dual axis solar tracker implementation on the Tinkercad free web application. As an experimental result show that the electricity generated by the proposed tracking system is total increase of about 8% to 22% over fixed-angle solar system.

Abstract: Timing error is now getting increased attention due to the high rate of error-occurrence on semiconductors. Even slight external disturbance can threaten the timing margin between successive clocks since the latest semiconductor operates with high frequency and small supply voltage. To deal with a timing error, many techniques have been introduced. Nevertheless, existing methods that mitigate a timing error mostly have time-delaying mechanisms and too complex operation, resulting in a timing problem on clock-based systems and hardware overhead. In the proposed work a novel timing-error-tolerant method that can correct a timing error instantly through a simple mechanism is demonstrated. By modifying a clock in a flip-flop, the proposed system can recover a timing error without the loss of time in the clock-based system.

Furthermore, in order to reduce power consumption in the stages were operation is not performed, gating mechanism is used to reduce the unwanted transition. Clock Gating computes the clock enabling signals of each FF one cycle ahead of time, based on the present cycle data of those FFs on which it depends. It has however a big advantage of avoiding the tight timing constraints of earlier methods, by allotting a full clock cycle for the enabling signals to be computed and propagate to their gaters. Due to the compact mechanism, the proposed system has low hardware overhead in comparison with existing timing-error-tolerant systems that can recover the error instantly. To verify our method, the proposed circuit is designed using Verilog HDL and simulated by Modelsim. Further, synthesis and power analysis is performed using Xilinx ISE.

Keywords: Error-tolerant systems, soft error, timing error, clock gating.

Abstract: The area of Bioinformatics has arisen from the needs of biologists to utilize and interpret the vast amounts of data that are constantly being gathered in genomics research. The ultimate goal of bioinformatics is to develop in silico models that will complement in vitro and in vivo biological experiments. Bioinformatics encompasses the development of databases to store and retrieve biological data, of algorithms and statistics to analyze and determine relationships in biological data, and of statistical tools to identify, interpret, and mine datasets. Database management, artificial intelligence, data mining, and knowledge representation can provide key solutions to the challenges posed by biological data. AI in bioinformatics provides both basic as well as clinical research with the help of biological sequence matching, proteinprotein interaction and function-structure analysis. This analysis helps in the design and discovery of drugs as well as complex systems. Deep learning (DL) has shown explosive growth in its application to bioinformatics and has demonstrated thrillingly promising power to mine the complex relationship hidden in large-scale biological and biomedical data.

Abstract: Recent advancements in web technology have given rise to numerous online shopping websites. However, online shopping comes with certain disadvantages. One notable challenge is the difficulty in visualizing how a particular garment would appear when worn, given the diverse variations in body size, shape, hair, and skin color across the human population. Ensuring the fit of clothing is of paramount importance to both customers and retailers. Our approach centers around assessing how a chosen garment complements the user's body and replicating its real-world appearance. This is achieved by identifying critical points on the garment and the user's body dimensions through image processing techniques. In this paper, we present an application designed, implemented, and tested to enhance the virtual dressing room experience
