To address the uneven distribution of thermal environment in buildings and temperature deviation between end sensing devices work area, this paper presents a simulation experimental study indoor characteristics its influencing factors, taking an office northern area as research object. Firstly, three-dimensional model building is constructed based on ANSYS software to simulate summer winter und...

Building penetrations are the most-potent elements providing daylight and moderating lighting energy consumption affecting indoor comfort consequent usage. In a semi-tropical climate with green environment such as Sydney, there is radical demand to extend windows views. This research aims optimize sunlight admission maintain while minimizing consumption. The method for investigation simulate mu...

Recently, expanded metal mesh has been used on the facades of many buildings in Taiwan. Therefore, this study, we evaluated impact natural lighting and energy consumption office buildings. First, compatibility EnergyPlus DIVA simulation software with was verified using field measurements. The results show a high correlation between measurement, except for some periods direct sunlight. Then, eff...

The paper is based upon the performance of various w indows in designing FIR Filter. The cosine hyperbolic w indow has been used to design a better FIR Filter in terms of ripple ratio, side-lobe roll off ratio and main-lobe w idth w ith its advantages of no power series expansion in frequency domain hence need less hardware. The spectral characteristic of cosh window is compared with other wind...

failure of the quay walls due to earthquakes results in severe economic loss. because of hazards threatening such inexpensive nodes of national and international transportation networks, seismic design of quay walls is still an evolving topic in marine structural engineering. this study investigates the sensitivity of the gravity-type quay wall stability respect to uncertain soil and seismic pr...

This research is focusing on the impact of changing position black painted side room (dark surface, or wall, ceiling floor) interior space illumination to determine best for dark surface inside room. The rectangular have six sides including and floor, every a it could be covered with low high LRV material, but this painting covering illuminance space. So, aim least negative if get material work...

A new simple form window with the application of FIR filter design based on the exponential function is proposed in this article. An improved window having a closed simple formula which is symmetric ameliorates ripple ratio in comparison with cosine hyperbolic window. The proposed window has been derived in the same way as Kaiser window, but its advantages have no power series expansion in its ...

Exposure to radiation from different types of television sets was measured to ascertain the levels of hazards posed to the human biological system. Measurement of the annual radiation dose hazards was performed using a halogen-quenched GM tube with thin mica end window having a density of 1.5 mg/cm2, effective window diameter of 0.360 inch and side wall of 0.012 inch thick. The GM tube was plac...

background: in order to improve the evaluation of possible rectal toxicity based on the rectal normal tissue complication probability (ntcp), we consider the fractional dependence of the ntcp on the wall thickness (tw) and rectal displacement (rm). materials and methods: the two-dimensional ntcp model (ntcp2d) was developed using radiotherapy plans of ten randomly selected patients with prostat...
