The Reynold’s equation and energy equation has been solved using finite difference method to study the effect of variation in offset factor on the performance characteristics such as oil-film temperatures, thermal pressures, load carrying capacity, power loss, and Sommerfeld’s number of offset-halves journal bearing. Numerical solution of Energy equation is achieved using Parabolic Temperature ...

—The rising share of energy generation of renewable energies leads to a more volatile energy generation. Large conventional generation capacities have to be kept in the system in order to smooth out the generation patterns of distributed generators. The controllability of electricity generation is on decrease. To improve adaptability of power systems due to these new challenges, the concept of ...

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...

Thermal modeling of an automotive cabin was performed in this paper to predict the inside cabin air temperature. To implement this task, thermal and ventilation loads were estimated and the mass and energy balance conservation equations for dry air and water vapor with considering a new parameter (air circulation ratio) as well as the balance equations of internal components of a cabin were de...

background: noise is one of the annoying agents in the environment and it is harmful agent in workplaces that its occurrence with work load, there are in many workstations. the aim of this study was to determine the combined effects of exposure to noise and work load on heart rate changes. methods: this cross-sectional study performed on 14 male students into climatic chamber in 2011.the mean ±...

The system reliability, performance, cost, and leakage power in deep sub micrometer era have a significant impact by thermal hotspots and temperature gradients. As the system complexity increases, it is very difficult to perform thermal management in a centralized approach due to state explosion and the overhead of monitoring the entire chip. In this work, a framework for distributed thermal ma...

The development of urban areas by densification of the existing urban infrastructure and setting up of new dwellings raises the question of spatial and temporal distribution of energy supplies to provide thermal comfort. Urban development projects are indeed not necessarily coordinated and may unexpectedly appear, either through new building projects or by opportunistic study of key area, or by...

Simple three point bending tests were performed on Ni-Ti wires with three different Af points (1 degree C, 13 degrees C and 34 degrees C) to clarify the relationship between Af temperature and load changes under constant deformation. Each wire was deformed at 37 degrees C and then thermal changes were imposed by temperatures of 2 degrees C or 60 degrees C. The load changes with thermal changes ...
