  • Identification of weak buses and elements participation in voltage instability of large multi bus power system

    In heavily loaded systems, voltage stability limit is usually dominant and voltage instability is usually observed following large disturbance. This is typically the case in the deregulated environment as the transmission systems are operating under more stressed condition due to increased transaction level associated with open access. In this paper simple voltage stability analysis is carried ...

  • Content Analysis of Toxic Elements in Soil by Simultaneous ICP

    Contaminated soil not only leads to contamination of untreated drinking water through permeation into river water and rainwater, it adversely affects health when the soil itself is directly ingested as a child puts the ground into a stoma into a play etc. Therefore, assessment of soil toxicity using a defined method is required. I In Japan, the Soil ...

  • EDXRF Analysis of Sulfur and Other Elements in Oil

    The concentrations of sulfur substances in fuel oil, which greatly contribute to air pollution and acid rain, are regulated by law in many countries, and these regulations are becoming stricter with the growing concern about their impact on the environment and the consequences for society. Here, using the easy-to-operate EDX-720 energy dispersive X-ray fluorescence spectrometer, we determined the ...

  • ICP Analysis of Multiple Elements in Drinking Water

    The amount of water typically consumed by an adult is said to be about two liters per day, and nearly all of this is tap water or mineral water, generally referred to as "drinking water." Conducting safety inspections are the responsibility of each country according to their respective regulations. Typically, there are many target elements included in the test, such as sodium (Na), calcium ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Finite element analysis of slip damping in riveted built–up beams

    Damping in built–up structures is produced by the energy dissipation due to micro–slip along the frictional interfaces. A finite element model of the linear elastic system has been formulated using the Euler–Bernoulli beam theory to investigate the damping phenomena in riveted connections. The discrete element system having two degrees of freedom per node representing ν and ∂v/∂x has been used ...

  • Finite element analysis of turbine generator rotor winding shorted turns

    Abstract Online magnetic flux monitoring via permanently installed air-gap flux probes is a well- established technology to determine the presence of shorted turns in a turbine generator rotor winding. Flux measurements are normally performed using flux probes installed in the machine air gap (on a stator wedge) and connected to portable or permanently installed instruments. In this ...

  • Optimal finite element modelling for modal analysis of liquid storage circular tanks

    Model analysis of liquid storage vertical tanks is a complex task due to fluid–structure–soil interaction. Analysis of tanks subjected to earthquake excitations using finite element modelling (FEM) has become a preferred technique. The FEM is validated by comparing its results with experimental and theoretical results in the literature. However, most finite element studies in literature do not ...

  • Theoretical analysis and finite element modelling of composite ferrocement–concrete beams

    Composite ferrocement–concrete beams have been introduced in the literature as a viable alternative for the conventional reinforced concrete beams. This paper presents a proposed theoretical and a three–dimensional non–linear finite element models for simulating and analysis of composite ferrocement–concrete system. The theoretical and the finite element models were used to analyse ten composite ...

  • Firmness evaluation of melon using its vibration characteristic and finite element analysis

    Analysis of the vibration responses of a fruit has been suggested as a non-destructive measure of its elastic properties (firmness). In this study, 'Huang gua' melons were excited using three types of balls (wooden, steel and rubber) and the vibration was detected by an accelerometer. The modulus of elasticity of the inner, middle and outer portions of melon flesh were determined using flat plate ...

  • Finite element analysis of buried continuous pipeline subjected to fault motion

    Pipeline generally extends over long distances traversing through wide variety of different soils, geological conditions and regions with different seismicity. Most analytical models developed in the past for pipeline fault crossing are of limited usage as models developed were useful only for strike slip fault. Incorporating the large geometric changes in analytical study is a tricky task; ...
