      Abstract: Steady state dynamic recovery Kinetics is defined to quantify dislocation density during macro and micro-scale ausforming. High-stress regime of ausforming is liable to follow the rate controlling dynamic recovery kinetics of thermal glide by rapid advancements of kinks. Crystallographic orientation,  specific Taylor factor,  is observed to increase the work-hardening induced dynamic recovery. Stacking fault energy,  is found to be inversely proportional to. Distance covered by kinks,  is expressed as dislocation spacing of opposite signs. Crystallographic texture component S is found to be dynamically recovered faster than Goss orientation.

      Abstract: The modern air conditioner cools by using refrigeration gases like Freon, CFCs, etc. Although these refrigerants produce good results, one of their main drawbacks is the release of hazardous chemicals that affect the ozone molecules. Attempting to make utilisation of air conditioners that cool using thermoelectric cooling modules, which operate by the Peltier effect, becomes an option to solve this problem. These modules safeguard the ecosystem by not emitting any dangerous substances. This study investigated those Peltier-based thermoelectric air conditioners. The Peltier Effect, a thermoelectric recirculation pump, was the primary cooling mechanism used in the system. This model does not require a compressor, moving parts for the priming, etc. Thermoelectric air conditioners are superior to traditional air conditioners in a number of ways, including reduced size, less weight, higher reliability, and the absence of mechanical moving parts. The project intends to test the Peltier system's cooling capabilities indoors. The suggested design is to offer a good substitute for air conditioners, which require a significant initial investment and waste a lot of power.

  • Effect of Advanced Processing on the Development of Nano Bainite

      Abstract: A comprehensive report has been tried to address associating the advanced processes to develop high performance bainitic steel. The effect of novel processing like iso-thermal processing, thixoforming, quenching-partitioning and ausforming has been justified on the development of carbide free nano bainite. The single-variable stage iso-thermal holding of 0.34C-1.52Mn-1.48Si-0.93Ni-1.15Cr-0.40Mo-0.71Al steel at the temperature range of 668K-563K has revealed that the bainite, which formed at just above martensite start temperature, was associated with both high strength and toughness. The iso-thermal banitic processing of steel with composition 0.74C-1.64Si-1.82Mn-1Ni-0.36Mo-0.21Cr-0.047Al at 513K, 543K and 573K, performed just after the thixotropic flow of prior 50% deformed feedstock, produced globular grain with size 115 µm containing mixture of ferrite plate (0.063 µm) and austenite plate (0.040 µm). High carbon steel with composition 0.79C-1.98Mn-1.51Si-0.98Cr-0.24Mo-1.06Al-1.58V deformed 15% in 10 second during ausforming at 573K, enhanced the nano bainite development throughout the process. An equivalent process to quenching and partitioning process revealed that the pre-existing martensite plate enhanced the nano bainite kinetic. However, the effect of ausforming was found to be stronger than the effect of pre-existing martensite.

  • Cause, Detection, Effects, and Securing of Fake Renewable Energy Powered
           Instrument Landing System Signals on Landing of Aircraft

      Abstract: In recent years, the alternate source of energy has gained significant focus across the globe as the emission of greenhouse gases has contributed to global warming ominously. Being pivotal in economic development, the aviation industry is getting attention to contributing to greenhouse gas emissions worldwide. The airport’s carbon footprint can be lowered by replacing the traditional energy supply with renewable power. The enormous compulsory spaces surrounding runways may be utilized for solar plants. The same renewable energy can power the instruments installed for airport’s communication, surveillance, and navigation systems. One of the important instrument systems used at such an airport is the renewal energy-powered instrument landing system (REPILS). The present research analyses the cause, detection, and effects of three different fake REPILS signals. The first one is due to two landing system installations at the airport. The second fake signal may be generated using software-defined radio. It may be transmitted as a powerful signal to dominate the actual transmission. Finally, the last fake signal combines with a portion of the valid one, causing a variation in the correct approach path. Their detection and effects and securing techniques for arriving aircraft have been discussed.

  • Framework and Technical Analysis of Pressure Vessel

    • Free pre-print version: Loading...

      Pages: 31 - 37
      Abstract: This project will involve developing pressure vessels for a variety of fluids. Fluids can be kept in pressure vessels at pressures other than atmospheric pressure. They are made to transport fluids under specific pressure and temperature conditions. Gas, oxygen, etc. 100 to 20,000 psi of pressure can be used to store gases. In contrast to ambient pressure, they may store gases at a specific pressure. Therefore, we need pressure vessels for storage purposes. The analysis and development of hydraulic systems are carried out in SOLIDWORKS, and the parameters taken into account when designing the pressure vessel include the minimum design temperatures, the maximal proper safety pressure, the temperature, the safety factors, and the corrosion allowance. The American Society of Mechanical Engineers' (ASME) Pressure Vessel and Furnace Code were used to design these pressure vessels. The study's main goal is to build a pressure vessel in accordance with ASME specifications and perform thermal analysis on the pressure vessel comprised of different kinds of materials by adjusting the shell thickness of the vessel for various ambient temperatures. Finding the ideal thickness that ensures that the pressure vessel is appropriate to utilize in industry requires comparing the results. The worst-case scenario also takes into account the possibility of a crack on the pressure vessel's exterior surface. Fracture mechanics is used to examine the various crack geometries in various types of materials determining the pressure vessel's level of usability and safety.
