Published: December 2020

The availability of Sanitary napkin pads is very much essential for the menstrual health of women in India. The cultural taboos associated with the menstrual health as well as the cost of the pads prevent are forcing many women to adapt to home-made clothe pads which are unhygienic and uncomfortable. Research has been going on in the manufacturing of low cost sanitary pads. The timely availability is more important than the cost of the napkins. In schools and colleges or in public places like railway stations, airports, bus stations while travelling people might find it difficult to find the stores or shops selling the napkins. Hence it is necessary to have a vending machine for easy access and availability at all times. The drawback of the system is that once the stocks are used up there is a time lag before the refilling of the stock. This can be solved by having a vending machine which accepts non cash transactions as well as that can inform the maintenance people the stock position. This helps in timely replenishment of the stocks to ensure round the clock availability.

Data Access Control has become a demanding issue in cloud storage systems. Access control is the protection method to control who can view or access the information in computing scenarios. Some techniques have been designed formost of the security strategiesprovidedtotheclients accessingtheuploadeddata. AQuantitative Sørensen–Dice Indexing Damgård–Jurik Cryptosystem based Data Access Control (QSDIDJC-DAC) method is introduced to avoid the illegitimate data access in the cloud server. Initially, the QSDIDJC-DAC method comprises five processes, namely registration, key generation, authentication, encryption and decryption for data access. At first, the clientsregister their information to the cloud server. After that, the cloud server generates the key pairs (i.e., public key, private key). Then the client encrypts the data with the general public key and sends it to the cloud server for storing the data. During the data access, the user transmits the request to the cloud server. Upon receiving the request, the authentication server verifies the cloud user is a legitimate user using the Quantitative Sørensen–Dice similarity coefficient with higher authentication accuracy. The Similarity Coefficient matches the requested user with user information stored in the cloud server on the time of registration. Based on the similarity value, the legitimate and illegitimate users are correctly identified with minimum time consumption. After performing the verification process, the cloud server allows legitimate users to access the data. Subsequently, the client decrypts the data with the help of their private key. This helps to enhance the data access control in the cloud server with a better security level. Experimental assessment is carried out on factors such as authentication accuracy, computation time and data confidentiality rate with recognize to some of the cloud users and thedata.

Design and Development of Multi Element Wing for Automobile Application
Authors: Palanivendhan M , Vengatesan S , Dutta Somyadeep , Jain Shubham
Published: December 2020

Vehicle aerodynamics is a broad encompassing field that describes the forces acting on an object when moving through a fluid. When stationary, the exterior surfaces of an automobile experience one atmospheric pressure; the upper and lower surface as well as the front and rear surfaces all have the same pressures exerted and ultimately achieve equilibrium with the summation of forces being equal to zero. As the vehicle starts to move through the fluid, the pressures exerted on the exterior surfaces change proportional to the square of velocity. These pressure changes create forces acting on the surface of the vehicle that can drastically hinder the performance of the vehicle. Aerodynamicists study this natural phenomenon to try and minimize forces that inhibit motion and, in some cases, develop these forces and use them to improve performance and safety. Vehicle aerodynamicists are primarily concerned with two dominant forces that interact with a vehicle; lift and drag. The management of these forces is crucial to the performance of any vehicle however the philosophy of vehicle aerodynamics differ significantly depending on the application. In this work introducing multi element in the rear of the vehicle to maintain the lift force and computational fluid dynamics analysis carry out to measure the performance of the multielement wing.

Published: December 2020

Electricity has become a desirable source of propulsion for automobiles for not leaving behind any pollutants during their running operation. The source of electricity comes from batteries connected together to deliver the rated amount of current in order to propel the vehicle and its auxiliary systems. Internal Combustion vehicles have improved significantly since their inception in the 1800s in terms of mechanical and thermal efficiency. However, only a fraction of the produced mechanical energy is utilized as the driving torque of the vehicle with the rest being lost as a result of mechanical and heat losses. Then comes the problem of harmful pollutants resulting due to the operation of the vehicles like unburnt Hydro Carbons, Carbon Monoxide and Nitrogen Oxides. Although the levels of these harmful exhaust gases have come down with the passing of emission laws around the world over the years, the zero-emission operation of all-electric vehicles is seen as an attractive option for transportation purposes. Electric vehicles negate the issue of mechanical losses by having the electrical power delivered directly to the wheels (through vehicles that use an in-wheel motor system which directly deliver the power to the wheel hub) or through a differential like in a conventional rear-wheel drive vehicle. The battery pack stores and delivers electric power to the wheels and the auxiliary systems. Like an Internal-Combustion engine, a battery pack delivers peak-discharge current (analogous to peak torque in an IC engine at a certain temperature) at a particular operating temperature of the battery pack. Therefore, it is vital to maintain the operating temperature of the battery pack to sustain the performance and the longevity of the battery pack. Prolonged exposure to high temperatures can significantly impact the power delivery and the life-cycle of the battery pack. The battery pack can be cooled by air, liquid or thermo-electric means. This research will be centered around air-cooling as it does not require any special components and it is economical. If the casing of the battery pack has larger surface area for cooling and is made up of materials which have good thermal conductivity, the performance and the longevity of the vehicle can be improved. Our objective is to design a casing and perform thermal and CFD analysis to visualize the thermal performance of the casing while rest (charging/discharging phase) and during motion.

Two-wheeler with higher cc engine (180 or above) or even lower cc bikes which has aerodynamic elevation for pillion section has many problems regarding safety as well vehicle’s balance at high speed with pillion riders. Sudden braking, sudden acceleration or jumping of vehicle due to road variation can be dangerous for the pillion rider. Two-wheeler especially motorbikes and scooters have extra safety hook design extension for pillion rider to hold for safety. Sudden braking causes the bike to decelerate. the upper and the lower body of the rider riding the bike will also decelerate. For the pillion rider his/her upper body will not experience the same forces as experienced by the rider. Pillion rider lower body will decelerate with the bike as its contact with the foot of the pillion rider at footrest. To properly balance his/her upper body, the pillion rider has to hold the hook extension provided, or by holding a bike structure or by holding the bike rider. Similarly, in case of acceleration, pillion rider’s upper body tends to lean backward. To balance the force again the pillion rider has to hold the hook extension or bike rider or any other bike structure for support. In this work decided to rectify this by introducing a retrofitted joint to ensure extra safety with proper seating angle for pillion rider either during acceleration or deceleration. The modification will help to reduce the drag and lift force experienced by the pillion rider. To do this have considered "TVS Apache rtr 180" beast model to carry out our simulation to find out suitable characteristics for retrofitted joint. To carry out part designing using SOLIDWORKS software. To find out suitable characteristics for retrofitted point by simulation using MATLAB software.

The contemporary work emphasizes the importance of using coconut inflorescence fibril as a viable alternate to manmade fibril in polymer matrix composites for application components undergoing wear. The extracted inflorescence fibril from coconut tree is exposed to mercerization treatment with 5% wt/vol of aqueous solution. The composite samples were fabricated by varying the fibril content (10, 20, 30 and 40 wt %) of fibril/polyester matrix. The composite specimens were subjected to wear test employing a pin on disc tribometric setup under dry sliding state. Design of experiments inspired taguchi analysis is employed for wear analysis. The experiments were performed for 16 trial runs for the load (5, 10, 15, 20 N), sliding distance of (250, 500, 750 and 100 m) and sliding velocity of (6.3, 12.5, 19 and 25.3 m/s) as the operating parameters. The parametric analysis revealed fibril content is the more inducing parameter which have a notable impact on the wear behaviour of the composites ensued by sliding distance. Artificial Neural Networks (ANN) is adopted to forecast the dry sliding wear behaviour of the composites over a broad scope of test conditions. The extensive experimentation leads to the conclusion that fortification of inflorescence fibril to the polyester resin resulted in improvement of wear resistance up to optimum fibril content and then decrease in wear resistance was observed when the fibril content increases. Finally SEM analysis was performed on the wornout surfaces to study the governing mechanism such as ploughing, wedge formation and fibril pullouts.
