Finite element analysis of UTM testing of Aluminium Alloy AA6082

Aluminum alloy AA6082 is one of the stronger alloys in its series and has high corrosion resistance properties. These properties combined with its light weight make it extremely useful in the aerospace and automotive industries. It is, hence, essential to test the given grade of aluminum and find out its mechanical properties and failure criteria for further applications in the industry. One of the major sources for testing the mechanical characteristics of a material is the Ultimate Tensile testing Machine (UTM). Tensile testing helps us to ensure a safe and high-quality material and to reduce the chances of failure in the respective field. The various mechanical characteristics provided as an output to the tensile testing experiment along with the interpretation of the flow curves obtained are necessary for the predicting the tensile behavior of the material (including necking and deformation homogeneity). Finite Element Method is a powerful tool used today for the simulation of such experiments and software using this are widely used to predict the mechanical properties of different materials, after validating a particular model. Another advantage is that it reduces the amount of material wastage as the validated model can then be used to find the mechanical properties of the given material under different boundary conditions, thus eliminating the need for those experiments. This project aims at developing and validating the uniaxial tensile test models of the proposed material, varying the strain rates, temperatures and material models, using the commercial FE software ABAQUS 6.14.

Carbon nanotubes based gas sensor

Carbon nanotube(CNT) based Gas sensors are at- tracting huge research interest as it gives high sensitivity, quick response, and stable sensors for industry, biomedicine, and more. The development of nanotechnology has opened a new gateway to build highly sensitive, cheap, portable sensors those who have low power consumption. The extremely high surface to volume ratio and the hollow structure of nanomaterials is perfect for the adsorption of gas molecules.Mainly, the advent of carbon nanotubes has boosted the inventions of gas sensors that exploit CNTs unique morphology, geometry, and properties. Upon exposure to some gases, the changes in carbon nanotubes properties can be determined by many methods. Therefore, carbon nanotube-based gas sensors and their mechanisms are widely studied. In this paper, a broad survey of current carbon nanotubes based gas sensing technology is presented. few experimental works done are reviewed. The types, fabrication, and the sensing mechanisms of the carbon nanotubes based gas sensors are discussed. The challenges of the research up to some extent are also addressed in this paper.

Acquisition, management, and delivery of drugs

The need for drug delivery is very critical especially in populous countries like India. Medication management plays an important part is ascertaining if the people in a country have access to the basics needs of healthcare. The system proposed in this paper would provide for medication management which includes acquirement of medications, management, and delivery of the drugs to the patients. This system would remove the need for going to the medical stores and reduces the unavailability of drugs for use. A composition of various technologies such as Big Data, Business Intelligence and Networking help in providing a solution to this problem. The proposed system in this paper addresses this need for medication management. The proposed system is expected to reduce the stress on traffic snarls as well in the cities in which it is implemented.

Optimization of turning process parameters for surface roughness in dry and wet condition of AISI 1045 steel using Taguchi method

The main purpose of today’s manufacturing industries is to produce low cost, high-quality products in short time. They mainly focused on achieving high quality, in term of part accuracy, surface finish, high production rate etc. So, the selection of optimal cutting parameters is a very important issue for every machining process in order to reduce the machining costs and increase the quality of machining products. In this paper, the cutting of AISI 1045 steel material under the wet and dry condition is carried out using CNC lathe machine. Taguchi method is used to formulate the experimental layout. The effect of cutting condition (spindle speed, feed rate and depth of cut) on surface roughness were studied and analyzed. The CNC turning machine is used to conduct experiments based on the Taguchi design of experiments (DOE) with the orthogonal L9 array. Optimal cutting parameters for each performance measure were obtained employing Taguchi techniques. The orthogonal array, signal to noise ratio and analysis of variance were employed to find minimum surface roughness. Optimum results are finally verified with the help of confirmation experiments.

A review of holographic optical elements in solar concentrator applications

Photovoltaic cells are used to convert sunlight into electricity; the commercial photovoltaic cells made up of silicon but the main drawback of the solar cells is low conversion efficiency. In order to improve conversion efficiency generally mirrors and lens system is used as conventional solar concentrators, in the fact they have some drawback of bulky in nature, high installation cost, need the tracking system to face the sun, and also concentrating both light and heat on the solar cell. To overcome these problems holographic solar concentrators were used as solar concentrators. Holography is one of the very promising technologies to produce solar concentrators; mostly volume phase holograms are used as holographic solar concentrators. The holographic solar concentrators have some major advantages of lightweight, cool light concentration, and selective wavelength concentrations for wavelength dependable solar cells. In this paper, a brief review and basic study of holographic solar concentrators have been discussed. The key contributions of each work examined here and different technologies also discussed. This review is useful to study about basic foundations and create new ideas for future research work.

Gait analysis: Approaches and applications

Gait analysis is systematic quantification and evaluation of human walking. It has applications in the field of clinical sciences, video surveillance, rehabilitation therapies, etc. Various state-of-the-science, as well as traditional approaches, have been used for evaluating the gait cycle. This narrative review provides a brief understanding of all such approaches and methods used by scientists and clinicians in India. State-of-the-science approaches include marker based systems, wearable or non-wearable, sensors system, support vector machine, etc. Whereas traditional approaches include observational analysis, videography, etc. 3D gait analysis provides reliable data, however, is currently in limited use due to high instrumentation and maintenance costs involved. Indian scientific community can benefit for traditional approaches which are low-cost, reliable, and can be easy to implement in all sort of set-ups with relative ease.
