 Abstract

The proposed paper analyses and models an interleaved Buck-Boost conversion using a PID controller. The Buck-Boost voltage converter is becoming prevalent in many applications due to the increasing need for energy. These methods have a broad variety of applications, including fuel cell power systems, solar energy systems (PV), uninterruptible electrical supplies (UPS), and electric vehicles. The BBC is still a crucial part of many technological systems, despite the issues. Because of its capacity to efficiently change voltage levels, it is helpful in many systems mentioned earlier. Researchers are still working to push beyond its boundaries and realize its full promise in a number of fields. Researchers have examined a variety of ways to address the issues of input current ripple, transient response, and efficiency to improve the performance of the BBC. This converter's capacity to be operated through shifting signals that are interleaved, have the identical frequency, but various phases, makes it stand out from other converters. The simultaneous operation of converters, which disperse current from the input across inductors, results in increased effectiveness and dependability in power electronics and also a reduction in ripples. This synergy considerably boosts the converter's conversion performance. The control approach for this converter is PID-based. In this work, we thoroughly simulate the interleaved Buck-Boost converter while carefully highlighting the results attained with the PID controller method was used.

 Abstract

Fiber Reinforced concrete (FRC) is concrete containing fibrous material which increase as structural and is gaining importance. It contains short discrete fibers thar are uniformly distributed and randomly oriented. The concept of using fibers as reinforcement is not new. Fibers have been used as reinforced since ancient time. Historically, horsehair was used in mortar straw in mud bricks. In the early 1900s, asbestos fibers were used in concrete, and in the 1950s the concept of composite materials came into being and fiber reinforced concrete was one of the topics of interest. Experiments were conducted on concrete cubs, cylinder and beam of standard size with addition of various percentages of human hair fibre i,e.. 0%, 0.5%, 1% and 1.5% by weight of cement fine & coarse aggregate and result were compared with of cement ,of plane cement concrete M-20 grade. For each percentage of human hair added in concrete , four cubes, three cylinders and three beams were tested for their respective mechanical properties at curing periods of 3, 7 and 28 days. Optimum hair fibre content was obtained as 1.5% by weight of cement

 Abstract

Network slicing (NS) is a main allowing technology used in cellular 5G wireless communication networks. NS is introduced by 3GPP (Third Generation Partnership Project) in releases 15 or 16. 5G network is standardized with more software implementation to provide better flexibility and support different services. Virtualization of network functions, commonly called VNF is a software-based technique to enable different function. The NS technique is mostly suitable for computing-distributed environments. Two different approaches are the random-access network function called as RAN and the core network function called as CN, which are used for fast network function deployment. Here, different algorithms are used for finding optimal solution with less complexity and time.

 Abstract

This empirical study investigates the intricate relationship between privacy concerns, data-sharing intentions, and gender differences among Instagram users. The research aims to measure the extent of privacy concerns users generally experience and how these concerns will influence the willingness of users to share data. A questionnaire was structured and administered to target Instagram active users with a sample size of 100 people, examining demographics, usage of the platform, content-sharing behavior, and privacy perceptions. The findings highlight significant privacy concerns, particularly with respect to data collection and sharing. Users' trust in Instagram's privacy measures, past experiences, and perceived benefits of data-sharing have come out as major factors. The regression analysis shows a positive impact of privacy concerns on data-sharing intentions, while gender differences have not exhibited any significant effect. This study gives valuable insights to digital professionals, policymakers, and marketers, stressing the critical role of privacy concerns in forming user behavior on Instagram in this digitally connected age.

 Abstract

India is still a backward and developing country. It is no surprise then that in a country such as ours depression is one of the most prevalent and common "mental health illnesses" that people suffer from along with "anxiety". Depression is a common mental disorder with over 280 million people of all ages, an estimated 3.8 per cent of the population suffering from it globally, as per the World Health Organization, It is thus expected that in the next ten years, depression will put more burden on nations than any other disease, as per World Bank.Jatropha curcas (Linnaeus) is a plant which belongs to family ''Euphorbiaceae and genus Jatropha''. This plant is native of America and is widely distributed, is also located in India, Africa, Asia and Europe where it grows in arid, tropical and sub-tropical environments. Its name derives from the Greek words "Jatros" (doctor) and "trophe" (food) which translates its medicinal traditional use.1 Such medicinal use is reported in diverse consumption of different parts of J. curcas, some of them through infusions for various conditions such as fever, burn, rheumatism, allergies, diarrhea, antidepressant intestinal cramping, healing , headach, sleeping.

 Abstract

Now a days hybrid composites materials becoming of key importance from an economical and ecological compatibility point of view using synthetic fibers such as carbon, glass, aramid, etc. is expensive because of higher cost of individual fibers. This requires alternative materials with less production cost and maximum strength. Naturally available jute and synthetic fiber carbon were used as reinforcement in this work. Natural fibers are inexpensive and synthetic fibers has greater strength which provides faster biodegradable rate compared to only synthetic composite materials such as glass, carbon and aramid, which are used as reinforcements and the cost become optimized. In this work, the objective was to develop, investigate and analyze the tensile behavior of a composite material using jute fiber and carbon fiber sandwich type composite. The results were studied. The experimental results shows that hybrid composites are having significantly greater value. The primary objective of the present work is to find the tensile properties of jute and carbon reinforced hybrid composite consists of 80% of jute and 8% of carbon fiber T-700 is used as a reinforcement and other 12% epoxy resin Ly556.

 Abstract

In both the real and virtual spheres of cyberspace, social engineering assaults have emerged as a key security concern. The goal of this study is to provide a comprehensive comparison of social engineering tactics and countermeasures employed in both of these settings. By comparing and contrasting the approaches taken in each case, this research hopes to shed light on the nuances of social engineering and the challenges inherent in reducing its risks. Better security measures for the physical world and the Internet could be developed with the help of the information gleaned from this inquiry into the complexities of countering social engineering attacks.

The aim of this paper is to study the effects of changes in interest rates on the performance of bonds issued by the Tunisian banking knowing that it is a significant component of financing. So, the bond issue is an essential link of investments. The studying of yield bond is an important first step. For many types of financial research. To date, this research has focused on the bond yield for banks. There regression models are tested by different methods. The first model is based only on relationship between Actuarial Rate of Return, maturity and coupon. The other models are prominent in the published literature on the bond yield.

Abstract: The present papers deals with historical events in Girish Karnad Tughlaq. It focuses on the Indian medieval history, myths and historical legends. There is a discussion between the old man and the young man regarding the political situation of the country wherein present rule contradicts with the past. Karnad projects the curious contradictions in the complex personality of Sultan who was at once a dreamer and a man of action, benevolent and cruel, devout the godless.
