This technology's main adoption areas are agriculture, supply chain, food sector, energy industries, Health care, Real estate, Voting system, and education sector. This paper reviewed existing related works and applications using blockchain technology. Forgery or fraud on medical documents is a significant ch Read More

Background: Electrical Discharge Machining (EDM) has been widely applied in manufacturing high strength and high hardness of mental material due to no mechanical forces in the EDM process. The discharge state, an important process parameter of EDM, directly affects the machining quality and machining efficiency. So, it is necessary to detect the real-time discharge state of EDM. Therefore, discharge state detection Read More

Background: Ball bearings are widely used in industry. They are core components of mechanical equipment. The research on the structural improvement of ball bearings is beneficial to enhancing the performance of bearing. Comparing with traditional structure, novel ball bearing has brought a lot of advantages and solved many problems in the working. Objective: The study aims to report the latest research on the str Read More

Background: People suffering from hearing and speaking disabilities have a few ways of communicating with other people. One of these is to communicate through the use of sign language. Objective: Developing a system for sign language recognition becomes essential for the deaf as well as a mute person. The recognition system acts as a translator between a disabled and an able person. This eliminates the hindranc Read More

Background: Polycystic ovary syndrome is commonly known as PCOS and it is surprising that it affects up to 18% of women of reproductive age. PCOS is the most usually occurring hormonerelated disorder. Some of the symptoms of PCOS are irregular periods, increased facial and body hair growth, attain more weight, darkening of skin, diabetes and trouble conceiving (infertility). It also came to light that patients suffering fro Read More

Background: Breast cancer causes millions of deaths all over the world every year. It has become the most common type of cancer in women. Early detection will help in better prognosis and increase the chance of survival. Automating the classification using Computer-Aided Diagnosis (CAD) systems can make the diagnosis less prone to errors. Multi-class classification and Binary classification of breast cancer is a challe Read More

Objective: The paper aims to solve the problem of determining the sliding surface of soil landslide, and to provide the basis for landslide stability analysis and prevention engineering. Methods: In this paper, the sliding surface is determined by field exploration and comprehensively determined by the FLAC3D numerical simulation method. At the same time, Sweden Arc Method and FLAC3D numerical simulation are used to make Read More

Background: The influence of the second air-gap length on the performance of permanent magnet synchronous motor is usually ignored. A comparative analysis is made of line-start high-voltage permanent magnet synchronous motor in this paper. Objective: The purpose of this paper is to analyze the influence of the second air-gap length on the motor performance. Methods: A 10kV 1000kW permanent magnet synchro Read More
