 Abstract

A heat pipe is an important tool for effective cooling performance of the electronic devices. The main focus of this paper is to review applications of heat pipe in electronic system. Miniaturization of chips and increasing processing speed decreases the heat transfer surface area and generates very high heat fluxes resulting in large temperature rise in electronics devices. Therefore, for an effective cooling heat pipe is a better selection because of its high efficiency and reliability. A major part of this review paper is allocated to applications of different types of heat pipe and modern trends in heat pipe technology. Nanofluids are dilute suspensions of nanoparticles composite materials with the specific aim of increasing the thermal conductivity of heat transfer fluids. Authors also analyzed some of the applications of heat pipes with nanofluid for electronic cooling.

In order to extend the useful life of a Wireless Sensor Network (WSN), Redundancy Management of Multipath Routing abstractions emphasize the use of many data pathways to improve system security and reliability against malevolent or unreliable nodes while balancing this against energy cost. In order to increase query success probability and network lifespan, these abstracts suggest voting-based intrusion detection techniques to find and eliminate malicious nodes, dynamic algorithms that modify settings at runtime in response to environmental changes, and mathematical models to determine the ideal redundancy levels for multipath routing.

 Abstract

The advent of 5G technology marks a significant milestone in the evolution of wireless communication, offering unprecedented speed, capacity, and connectivity. This review paper dissects the core architecture of 5G, addresses critical security concerns, and explores its novel applications. We begin by examining the Next-Generation Radio Access Network (NG-RAN), which leverages millimeter wave communications, massive MIMO, and advanced channel coding and modulation techniques to enhance data rates and connectivity. The 5G Core Network (5GC) is highlighted for its service-based architecture, network slicing, and the separation of control and user planes, which collectively contribute to greater network flexibility and scalability. The roles of Network Function Virtualization (NFV) and Software-Defined Networking (SDN) in providing dynamic resource allocation and centralized network control are also discussed. Security concerns inherent to 5G, such as network slicing security, user privacy, authentication, and secure communication, are critically evaluated, underscoring the need for robust security measures and compliance with data protection regulations. The paper then delves into the transformative applications enabled by 5G, including Enhanced Mobile Broadband (eMBB) for high-speed internet and multimedia services, Ultra-Reliable Low-Latency Communications (URLLC) for applications like remote surgery and industrial automation, and Massive Machine-Type Communications (mMTC) supporting IoT and smart city initiatives. Emerging trends and future directions, such as the integration of Artificial Intelligence (AI) and edge computing, standardization efforts, spectrum management, and energy efficiency, are explored to provide insights into the ongoing evolution of 5G technology. The paper concludes by summarizing key findings, identifying open challenges, and discussing the potential long-term impact of 5G on various sectors and society as a whole. This comprehensive review aims to provide a clear understanding of 5G technology, its current state, and future possibilities.

 Abstract

For a given sequential data such as stock market prices or streaming stories in a newswire, we might be interested in when these data change in some way, such as a stock price falling or the document topics shifting. This abrupt change can cause shift in sequence and divide the sequence into two parts. For example If n items are put to test their lives then their lives will be x_1,x_2,.....,x_n. If there is one break in sequence, then sequence is divided into two parts. Suppose the change occurs at point mth, the sequence will be x_1,x_2,.....,x_m. and x_m,x_2,.....,x_(n+1). If we view our data as observations from a generative process, then we care about when the generative parameters change. Now the problem is how to detect and estimate the break point. For a given sequential data such as stock market prices or streaming stories in a newswire, we might be interested in when these data change in some way, such as a stock price falling or the document topics shifting. The goal of this paper is to explain a technical report on Bayesian changepoint detection and estimation by applying the Bayesian preliminary test estimation(BPTE) method in my research work, and to work through the framework and code for a Weibull model.

 Abstract

Online business transactions have been an important tool in today's world. The Selling and purchasing of goods has also taken a paradigm shift in recent years with people selling and purchasing goods through online portals. It offers two things that the regular market could never provide i.e. (a) Convenience and (b) range to choose from. It also saves time as the buyer no longer need to go to the market and select something from a wide range, which would take more time and would be a more expensive practice. The paper attempts to study the issues concerning market competition and fair standards of trading in online food delivery Apps vis a vis the Competition Act ,2002. The core areas causing bargaining power imbalance and information asymmetry between e-commerce marketplace platforms and their business users have been discussed.

 Abstract

In this article, a combination of Homotopy Analysis Method (HAM) and Integral Transform (Laplace method) with less computation is proposed to solve nonlinear wave equations. Based on this method, schemes are developed to obtain approximation solutions of Schock wave, soliton and travelling type solution for nonlinear wave equations. The proposed method is called Homotopy Analysis Transform Method (HATM). The results of applying this procedure to the studied cases show the high accuracy and efficiency of the new technique. The study represents the significant features of HATM also.
