Industrial accidents are grave mishaps that result in injuries and fatalities to people and damage to property as well as the environment. The impact of the accident is exorbitant and society has to pay for decades. In most of the developed countries, the wellbeing of people and the environment is a top priority. The noble mission for every nation should be to reduce the level of the accident to "Zero" by adopting the Read More

Background: The manufacturing sector has observed dynamic changes during the last few years, from the product-oriented local economy to the customer-driven global economy. In this environment, manufacturing systems have been required to deliver highly flexible, demanddriven and customized products. Hence, the Multi-Agent System (MAS) technology can play an important role in making highly responsive productio Read More

Nanoalloy clusters have attracted a lot of attention in recent times and have grown enormously in various domains, ranging from semiconductor, material sciences, biophysics, life sciences to earth sciences. In this report, we presented a review of nanoalloy clusters and their application. The background of clusters, nanoalloys and their isomers, their classification, and potential applications ranging from catalysis, optoelectroni Read More

Aims & Objectives: Producing thin-walled rotationally symmetrical parts of difficult-tomachine materials by electrical discharge machining is an evolving field of research. Poor heat transmissivity, high hot strength and in-process deflection of thin-walledd Inconel 600 parts pose a great challenge for its processing by conventional machining methods. Methods: In this study, a novel hybrid process called Centreless Electric Read More

Background: Wireless sensor networks play a significant role in network technologies. It is difficult to determine an optimal route that satisfies the requirements of wireless sensor networks. Energy- aware and trust-aware routing protocols play a critical role in the security of wireless sensor networks. SRPMA routing protocols have limited parameters and functions. The ant colony algorithm is specifically designed to find the r Read More

Background: Modular Steel Buildings (MSB) are extensively used in petrochemical plants and refineries. Limited guidelines are available in the industry for analysis and design of (MSB) subject to accidental Vapor Cloud Explosions (VCEs). Objectives: The paper presents a simplified engineering model for Modular Steel Buildings (MSB) subject to accidental Vapor Cloud Explosions (VCEs). Methods: A Single Degree of F Read More

Background: Rolling mill vibration mechanism is very complex, and people have not found a satisfactory vibration control method. Rolling interface is one of the vibration sources of the rolling mill system, and its friction and lubrication state has a great impact on the vibration of the rolling mill system. It is necessary to establish an accurate friction model for the unsteady lubrication process of the roll gap and a nonlinear vibrati Read More

Background: The PWM Boost converter is a strongly nonlinear discrete system, especially when the input voltage or load varies widely, therefore, tuning the control parameters of which is a challenge work. Objective: In order to overcome the issues, Particle Swarm Optimization (PSO) is employed for tuning the parameters of a sliding mode controller of a boost converter. Methods: Based on the analysis of the Boost conv Read More

Nowadays when everything is digitalized, internet and web play a vital role in everyone’s life. When one has to ask something or has any online task to perform, one has to use the internet to access relevant webpages throughout. These webpages are mainly designed for large screen terminals. But due to mobility, convenience and economic reasons, most of the persons use Small Screen Terminals (SST) like mobile phone, palmt Read More

Background: Segmenting an image into multiple regions is a pre-processing phase of computer vision. For the same, determining an optimal set of thresholds is a challenging problem. Objective: This paper introduces a novel multi-level thresholding based image segmentation method. Methods: The presented method uses a novel variant of whale optimization algorithm to determine the optimal thresholds. For experimental valid Read More

Background: In recent years, patents suggest that four-wheeled robots have been widely used in outdoor reconnaissance fields. However, the emergency obstacle avoidance of the fourwheeled robot on the slope is affected by the slope angle and the friction coefficient of the slope, and its motor torque and yaw torque are prone to abrupt changes, causing the four-wheeled robot to slip greatly. According to relevant literatu Read More
