Indicating Human Activity Intensity using Accelerometer
Abstract: In this paper, we propose to develop a system that senses the human activity and indicates the intensity of action performed. Intention is to broadly classify human as inactive, underactive, overactive and hyperactive by simply turning on the LED of the system corresponding to the data received on the controller from ADXL345. The focus is on the fact that energy expenditure is related to the sum of integral of values …

Time History Analysis for an Underground Powerhouse Structure Considering Soil Interaction
Abstract: AbstractThe project deals with the analysis and design of an underground powerhouse constructed on three different soil types (silty, sandy, clay). Though each powerhouse has mostly similar components and machines but the analysis and design of civil structures in a plant are always done with different ideas and optimized techniques. Hence this paper is based on some new and different considerations in analysis and design aspects and optimization. The objective …

Small-Scale Model Study on the Load-Deflection Characteristics of Single Piles under Static Lateral Load
Abstract: The capacity of a certain mathematical model to mimic a behavior occurring on a larger scale often concerns engineers. To evaluate a particular structure's safety factor, model uncertainty is an important consideration. Piles have been widely used to support axial and lateral loads for a wide range of structures, including high-rise buildings, transmission towers, power plants, offshore structures, highway and railway structures. Many transmission towers, high-rise buildings, highway and railway …

Analysis of Natural Frequency for Three-Dimensional Model of Transformer Winding Using FEA
Abstract: AbstractPower transfer winding is prone to a number of events of a short circuit. However, over a period of time, capabilities of winding to withstand forces generated during such events decrease. In order to understand the behavior of winding at excitation, study of natural frequency is an important parameter. In this paper, winding’s radial and axial modes are studied with the help of finite element approach. Three-dimensional (3D) and two-dimensional …

BUCKLING ANALYSIS OF COMPOSITE CYLINDRICAL SHELL STRUCTURE USING FINITE ELEMENT ANALYSIS
Abstract: When designing cylindrical shells one should consider not only the strength problem in service, but also the buckling problem. Cylindrical shells such as thin-walled structures are susceptible to buckling when subjected to static and dynamic stresses. The vessels are exposed to dynamic sea conditions depending on their usage. The functional failure of a pressurized composite vessel or a composite pipe in the form of leakage or weeping of the contained …

A Contribution to the Frequency and Transient Analysis of High Voltage Bushings
Abstract: The paper suggests a method for determining the frequency characteristics and transient response of capacitively graded high voltage bushings. It is based on an s-domain circuit model that describes the grading conducting foils and the insulating layers. In most cases, they are of different axial lengths. A system of simultaneous differential and algebraic equations is derived taking these differences into account. Its closed-form solution, subject to the boundary conditions, can …

Scheduling of PCB Assembly Using Particle Swarm Optimization Algorithm
Abstract: This paper deals with the problem of scheduling ‘N’ printed circuit boards (PCBs) on a single machine equipped with an automatic component interchange mechanism. The total number of different components required to process all ‘N’ PCBs is greater than the capacity of the spool. If the essential components are not on the spool, then one or more component switches must take place earlier than the PCB can be processed. The …
