Background: In this study, measurement of indoor radon and its progeny levels was carried out in Gas Turbine Power Station in Haryana ( India ), where natural gas is used as fuel. For comparison, the results of a study carried out in thermal power plant in Haryana are also presented. Radon being a ubiquitous air pollutant has global impact and its monitoring in the environment at work places is...

This paper presents a simplifiedlagrangian multiplier based algorithm to solve the fixed head hydrothermalscheduling problem. In fixed head hydrothermal scheduling problem, waterdischarge rate is modeled as quadratic function of hydropower generation andfuel cost is modeled as quadratic function of thermal power generation. Thepower output of each hydro unit varies with the rate of water discha...

Cold atmospheric plasma (CAP) has received great attention due to its noteworthy ability, and has also been widely studied over few decades in physics, biology and medicine. The purpose of this study is to evaluate the cold atmospheric pressure plasma effects on the proliferation of breast cancer cells. MDA-MB-231 was used for this experiment. MDA-MB-231 cells were cultured in 24-well plate and...

In this work, we characterize the power and thermal characteristics of a Pentium M system in response to a widely available power-management mechanism, DVFS (dynamic voltage and frequency scaling) and cooling capacity. We observe transient and steady-state responses to changing the DVFS state with custom microbenchmarks and develop a model that captures the power-thermal relationship for this s...

Abstract: A novel converter that can directly transform electrical, wind, hydraulic and other types of mechanical energy into thermal energy is presented in this study. First, the thermal energy of the converter is classified and then calculated by a finite element method. The eddy current distribution in the stator of the converter is also discussed. Second, the temperature field of the conver...

Wind sensors are widely used in many critical applications, such as navigation, weather forecast, aerospace and wind energy assessment. The thermal wind sensor can measure wind speed and direction at the same time, by measuring the temperature gradient on the sensor's surface which is induced by the wind flow. Compared to traditional mechanical wind sensors, there are two main advantages for th...

This paper focuses on the design of a 10 MW hybrid power plant using the technical specifications (data sheet) of an industrial solar panel. The main purpose was to find out the exact electrical properties of the solar panel specialy with conjunction to its temperature, to optimize overall output energy. We first describe the most important types of solar power plants and afterwards focus on el...

This paper investigates three models to implement Tradable Green Certificates (TGC) system with aid of game theory approach. In particular, the competition between thermal and renewable power plants is formulated in three models: namely cooperative, Nash and Stackelberg game models. The price of TGC is assumed to be determined by the legislative body (government) which is fixed. Numerical examp...

Background and Aim: Diode laser is a great choice for soft tissue surgery. The diode laser is partially absorbed by hard dental tissues, making it safe for soft tissue surgery. This study aimed to compare the tissue thermal changes induced by three types of diode lasers at 810, 940, and 980nm wavelengths. Materials and Methods: In this in-vitro experimental study, using a diode laser device (c...

Power semiconductors can be modeled as a thermal network of resistors and capacitors. The thermal boundary condition of such a model is typically defined as the heat sink surface temperature which is assumed to be constant. In reality, the heat sink surface temperature underneath the power module is not exactly known. In this paper we show how to set up a thermal model of the heat sink in form ...
