A study on crack propagation and life expectancy
Cracks are the most common flaws that are usually observed occurring on metallic surfaces, however, the existence of a crack on any material deteriorates the overall strength of the component and in turn, becomes the prominent reason for the failure of the component. The purpose of this research is to find out the behavior of a crack when the component is put to undergo cyclic loading. The study of cracks comes under the section of the vast concept of 'Fracture Mechanics’. The concept gives detailed information about the formation and expansion of cracks and also contributes largely in determining the probable failure time of a component under cyclic or fatigue loads. It’s important to know the life of a component keeping the existence of a crack of even the smallest size under consideration. The project uses concepts and information from fracture mechanics and forecasts the process of propagation of cracks on metal and determines its life under a given loaded condition. To determine the life of the component pre-established relations and formulae are used and results are obtained using a numeric and graphical approach.

Air conditioning using Peltier effect
The current air-conditioning system does cooling by refrigerant gases such as Freon, CFCs, etc. While these refrigerants provide good output, their major disadvantage is the emission of harmful gases that damage the ozone layer. A way to overcome this issue is by making use of air conditioners that use thermoelectric modules for cooling, which work by the Peltier effect. These models do not emit any harmful agents, thereby protecting the environment. This project discussed in the paper deals with the study of those thermoelectric air conditioners using the Peltier module. Conventional compressor run cooling equipment has more limitations related to energy efficiency and Chloro-Fluro Carbon (CFC) refrigerants use. Both these factors indirectly point to the impending scenario of global warming. As most of the electricity generation relies on coal power plants, which add greenhouse gases to the atmosphere is the more cause of global warming. Thermoelectric air conditioners have multiple advantages over conventional air conditioners, like, they are smaller in size, they weigh less, have high reliability, have no mechanically moving parts, and no working fluid. This paper focuses on a Peltier Based Air conditioner that will be easily portable

Comparative study of Stainless Steel and Aluminium Alloy for static structural analysis of quick release coupling used in the steering system
The paper presents the design and analysis of Quick release coupling. Finite element analysis is used to evaluate the performance under severe turning of steering wheel conditions by comparing two materials. Aluminium Alloy and stainless steel are used as quick-release materials. DS Solidworks 2020 and ANSYS 19.2 are used to design and carry out the analysis for determining the distribution of forces, variation of stresses, and deformation across the quick release. The most reliable and efficient material of quick release coupling which is required in FSAE competitions is determined. Static structural analysis has been carried out using the axis-symmetric finite elements. To get appropriate results the model is divided into discrete elements so that the forces are applied effectively in each region

Digital rupee – dissecting the viability of CBDC in India
Crypto Currencies are gaining widespread attention all around the globe. Given many of the disadvantages and high risks involved in crypto transactions, new emergent mechanisms of exchange like Central Bank Digital Currency (CBDC) are entering the market domain which seems relatively promising and less risky. Indian economy can be characterized by ever-rising Non Performing Assets (NPA), low money multiplier, tax evasion, poor tax base, the menace of black money, and high currency deposit ratio (CDR); our research finds that CBDC along with effective policy intervention mechanism can act as a panacea towards ebbing out such perplexities which the economy is confronting. Research points out the poor banking habit among the Indian population which is the primary driving force behind the big divorce between theoretical and actual money multiplier in India. Implementation of CBDC has the requisite potential towards developing banking habits in the masses. Akin to two faces of a coin, with charms come concerns and in the same consonance implementation of CBDC also poses some daunting challenges. First and foremost is the concern of data security in the contemporary milieu when the advancement of science and technology is at its zenith and concomitantly cyber crimes have been witnessing a spur. However, CBDC is a form of cryptocurrency which is characterized by the storage of data using blockchain technology. Under the blockchain framework of data storage, pieces of data are stored in a decentralized manner which makes data theft and deletion an arduous task for cybercriminals. The use of mechanisms like ‘Tokenization’ can also contribute towards securing the data of depositors and preventing frauds and scams. Another impediment in the way is the existing digital divide in the economy, however, implementation of CBDC mechanism in a phased and targeted manner can curb out this impediment to a greater extent. The unprecedented economic crisis owing to the pandemic might have devastating implications in the future and in order to rejuvenate and get all cylinders firing for the Indian economy, CBDC implementation is a dire exigency given the implementation is efficient and in a phased and targeted manner.

Fire and safety in building
The point of this examination was to analyze fire security measures and their practicality in structures, the necessary measures are innovation-based. Structures ought to be planned so that inhabitants can escape without help from anyone else in the event of a fire. In any case, contextual investigations show that inhabitants frequently are discovered unable to escape on schedule and generally subvert precautional estimates needed to stay away from or get away from fire. The investigation approach depended on occurrence assessments what's more, genuine analyses, for example, unannounced clearing drills. The potential outcomes of computer-generated reality for examining human conduct in flames are up until this point scarcely received by specialists. By the by, since in virtual conditions test people can be confronted with the marvel of fire in a protected manner, Data was too gathered from books, magazines, diaries, and related articles, the application of a social evaluation and examination device in augmented simulation is required to be a significant enhancement on the current examination techniques. In everyday little data is thought about genuine human conduct in an occasion of fire flare-up. Thusly, it is smarter to let the fire security of structures be founded on genuine human conduct in the fire. It is critical to edify tenants on security measures to be taken during fire flare-ups in and around their structures and other fire counteraction techniques to embrace for their wellbeing. The investigation suggested reasonable fire security measures in understanding to best practices after due assessment of existing fire security measures as it applies to clients and the adequacy of these actions.

Design and analysis of underground water tank using STAAD Pro software
The water tank is a structure used to store water for supplying to households for drinking purposes, for industries as a coolant, and irrigational water for agricultural farming in some areas. Water tanks are classified on basis of their shapes and position of structure. In this paper, we had discussed the design of an underground water tank of Rectangular shape that is Designed and analyzed using Staad pro. Underground water tank faces a different type of loads compared to other structures, they mainly face horizontal or lateral loads due to earth pressure and water pressure or any liquid pressure which is been stored in the tank. The sidewalls of the underground water tank will face greater load at the bottom and the load linearly decreases towards the top.
