Abstract: The Steel structures can undergo a natural process called corrosion, which can compromise their safety and durability. Given the inevitability of corrosion, it is crucial to evaluate the load-carrying capability of corroded structural components. This study aimed to investigate the impact of localized corrosion on the load-bearing capacity of tubular steel columns subjected to eccentric compression, by conducting parametric finite element analysis and examining the effects of the degree of volume loss (DOV) due to corrosion damage along the column on its residual compressive strength. Additionally, the reliability of corroded steel tubes was evaluated using normal distribution in MATLAB, to estimate the probability of failure and assess the risk of failure.

Abstract: India constitutes 10 % of the world’s tractor market share whereas in implements only 1 % market share of the world is held by India. Among implements, the rotavator is one of the highest-sold implements by volume. Hence advancement and improvement in the performance of rotavator operation are of importance via the advancement of technology. Currently, there have been such advancements and the products are available in the market to increase the performance of the rotavator. This study segregates the current advancement in rotavator technology into two sections namely mechanical advancements and instrumentation-based systems. Mechanical advancement technology includes multiple shaft rotavators that intend to reduce the operation time and achieve the pulverization level with a single pass. Another technology is the multi-rotor gear system, wherein the drive ratio is changed manually or through a shift lever to provide different rotavator blade RPM for different crop and soil conditions to attain desired performance. There has also been a lot of development in the design of blades which is covered in this study since rotavator blades pulverize the soil. Hence it is an important mechanical part that directly interacts with the soil. In an instrumentation-based system, a digital rotavator system has been studied indicating the optimal zone of operation with rental and serviceability parameters intended to improve pulverization, achieve high field capacity, and less fuel consumption. There has been a study to indicate the ratio of the peripheral speed of the rotavator and the forward speed of the tractor through instrumentation to improve the pulverization over the current practice. This paper intends to present a study on the current rotavator products being developed which are presently in operation to have a whereabouts and comparison of the recent trend in the advancement of the technology, the way forward, and the amount of improvement from the earlier practices.

Abstract: The effort each farmer takes to produce food grains has to be appreciated and we should minimize the wastage of food grains. To solve the problem of wastage of food grains in Fair Price Shops due to factors like poor storage, transportation or poor management, we’ve been working on Decentralized Public Distribution System using blockchain. By this we might able to track from where the food grains have been purchased and how it is transported and stored. Also we can track it up to how it reaches the public. By tracking this we can come to an idea of how to not waste food grains and also audit it properly. This will create an impact in the traceability of food grains so that we will be able to minimize the wastage of food grains during the supply. This will also point out the suspicious activities that takes place in the supply chain. This application also helps to audit the food chain and store transactions in an organized manner. Everyone will be accountable for the food grains they’ve wasted and they’ll try to act more responsibly than before. This idea will also make the existing system more secure, advanced and automated.

Abstract: This study examines the use of paraffin as a phase change material (PCM) with various concentrations of graphene nanoparticles for cooling battery packs using numerical and experimental methods. To test their impact on battery cooling, we specifically added 100 grams of paraffin and utilised 1%, 5%, and 10% graphene. The primary objective of the study is to assess the thermal performance of a battery pack using PCM-based cooling at various discharge rates. To simulate the cooling process, a computational fluid dynamics (CFD) model was created, and experiments were run to confirm the numerical findings. The study’s findings demonstrated how greatly adding graphene nanoparticles improved the PCM-based cooling system’s ability to transfer heat. As the percentage of graphene in the battery pack increased, the CFD simulations projected a drop in temperature, which the experimental data confirmed. The 10% graphene combination in particular produced the finest cooling results. The work offers insightful knowledge into the planning and improvement of PCM-based battery pack cooling systems, with the utilisation of graphene nanoparticles as a potent boost. The findings can be utilised to create battery cooling systems for a variety of uses, such as electric vehicles and renewable energy storage systems.

Abstract: There are a lot of features in our system(laptop/desktop) where no change has been made for long time and need to be upgraded ,like TOT (time out timer) to make the system go into sleep mode, and no proper energy saving algorithm based on detection of the outside world. This paper presents the system with an idea and implementation that outsmart the previous technology still in use. Computer vision being one of the branches of artificial intelligence that teaches and equips machines to comprehend the visual environment has many applications in today’s world and can offer lot in this as well. Digital images and deep learning models may be used by computers to precisely detect, categorize, and respond to things. Based on that, our ideas make the system capable of preventing person from coming very near to screen thereby preventing eye strain, taking smart decision to shut down the system if someone left the system running (even if movie is playing) and forget to shutdown. Not letting the system to go into sleep mode if anyone is there and looking (reading) at screen. These all features as a result somewhat also help in safety of the system, prolong the system’s life and save energy. Looking at the world report on vision by WHO, there are billions of people facing eye issues and many of that could have been prevented as per the report, so these features could have also helped at base level to at least reduce this number by prevention.

Abstract: Fiber reinforced recycled rubber beam can offer a perfect solution to meet the demands of sustainable structures with superior strength and flexibility. It combines rubberized concrete, steel fiber and percentage replacement of rubber and steel fiber to enhance the strength, stability, durability and overall performance. This paper presents the results of recent experimental investigations on rubberized concrete. Chipped and crumbed tire rubber particles were used to replace coarse and fine aggregate with varying percentages of replacement levels. The replacement levels selected were 25%, 50%, 75% and 100% by volume of the coarse and fine aggregates. Steel fibers were also added to the concrete mix to improve the performance of the concrete. The mechanical and fracture properties of the rubber concrete were examined. The optimal replacement ratio of the rubber particles have also been analysed to meet the strength requirements and fracture criteria.

Abstract: This paper represents experimental investigation carried out to study the effect of magnetic field on energy savings in vapour compression refrigeration system. By applying magnetic field at liquid line, atomization of the fluid will takes place and reduces the specific volume of the fluid molecules. The reduction in specific volume of fluid molecules leads to drop in the viscosity that reduces the pumping power required by compressor as well as increases heat transfer in vapour and condenser due to raised mass flow rates of the refrigerant. The COP was initially measured without application of magnetic field, and then magnetic field applied to liquid refrigerant in different positions. The strength of each magnetic pair was 100gauss. By the impact of magnetic field by the magnetic pair in different positions at liquid line, the COP increased upto 41.36% for R134a refrigerant when compared to simple VCR.

Abstract: Solar energy is inexhaustible and has a strong affinity to give surplus power among other sources of renewable energy which is received on the surface of Earth. The study focused on the design of tubular-type solar air collectors where the tubes are placed adjacent to each other at an equidistance of 10.08 mm and are made from a conductive material like aluminium. The parameters of design namely size and volume flow rate from an air heater are estimated by assuming that it gives a maximum efficiency of 35% with a flow rate of 0.0125 kg/s. The other parameters like the equivalent diameter of the duct, number of tubes, Reynold number, frictional effect, pressure drop, and power consumption by fan used in tubular type solar air heater are evaluated for an airflow rate of 0.0125 kg/s. The diameter of tubes used in the tubular solar heater is selected based on the heat removal factor and it is available in standard size here it is considered as 38.1 mm for analysis. The newly designed solar air heater maximizes the usage of solar energy in the tubular absorber surface and gives a maximum temperature of the air at the exit.

Abstract: The most versatile metal additive manufacturing technology, known as laser powder bed fusion, has been shown to produce geometrically challenging, high-performance metallic objects in near net shape with up to 99.9% relative density in a shorter amount of time. The most common engineering materials utilized for structural and sub-structural applications are steels and iron-based alloys. Steels have distinguished themselves from other metallic materials thanks to their availability in more than 3500 grades and a variety of qualities, including high strength, corrosion resistance, good ductility, low cost, and recyclability. However, the LPBF process for steels and iron-based alloys has not yet been fully adopted in industrial applications because there is little information about the processing conditions currently available, there are no specific materials standards, a lack of knowledge to correlate the process parameters, and there are other technical challenges like part variability, dimensional accuracy from a design model to an actual component, limited feedstock materials, and manual post-processing. The purpose of this review is to provide an overview of the steels and iron-based alloys used in the LPBF process by summarizing their key process parameters and microstructure evolution during solidification, as well as highlighting metallurgical defects and potential control methods, all of which have a direct impact on mechanical performance.

Abstract: In the last few decades, the rate of fossil fuel consumptions have increased drastically, causing severe environmental challenges. So, it is very important for us to consider of a sustainable eco-friendly alternative fuel. In such, use of hydrogen as an alternative fuel can be done due to its special properties like wide range of flammability, zero carbon content etc. This research work is based on 5% hydrogen addition in diesel at 3.5 kW rated power with a constant speed of 1500 rpm. This research is carried out on single cylinder, 4-stroke, water cooled, CRDi diesel engine at 0-80% load. The conclusion of this research was that the NOx emission increases compared to diesel fuel, but particulate matter decreases significantly. CO emission decreases with 5% hydrogen addition in diesel. NO emission decreases at low load conditions with hydrogen addition but at higher load it increases slightly. CO2 decreases at low load condition with hydrogen addition in diesel. HC decreases at higher load with hydrogen addition in diesel, but at low load condition, it increases slightly. Brake thermal efficiency increases at higher load condition with hydrogen addition in diesel. Brake power and BSFC for 5% hydrogen addition in diesel however showed slight difference in performance at varying load conditions.

Abstract: In India, a large portion of rain-fed land has low productivity, is at high risk, has little exposure to technology, and is vulnerable to the degradation of natural resources. Watershed Development Programmes (WDP) have been started in India to improve the production and sustain the ecology in dry and semi-arid areas by adopting appropriate technology in production and conservation, along with fulfilling the basic necessities of communities for food, water, and shelter. In the present study area of the Itagi watershed, various types of water and soil conservation structures, such as contour bunds, check dams, farm ponds, recharge pits, earthen checks, rubble checks, etc., were constructed in an area of 4636 hectares under ‘Sujala’ WDP during the year 2004. The total costs of these soil and water conservation structures were Rs. 356.6 lakhs, including administrative costs of Rs. 19.81 lakhs. The present paper reveals the impact of WDP on crop area, productivity, and benefit-cost ratios of various crops. The analysis of the data illustrates that after the implementation of the WDP, the productivity of various crops has increased by 16–80%, the area of cultivation has increased, and the benefit-cost ratio for all the crops has increased.In addition, many more benefits, like a change in cropping pattern, groundwater recharge increment, reduction in soil erosion, increased employment opportunities, etc., were also noticed.
