background: in the steel industry, coke-fueled furnaces are used for smelting iron ore to produce cast iron are considered as sources of annoying noise.this study aims to evaluate the noise pollution blast furnace and sound source characteristics in order to present noise control measures in the steel industry. methods: measurement of noise level and its frequency analysis was performed using s...

The number of public displays is rapidly increasing due to their decreasing prices and the advantages of their dynamic behavior. If the displayed content depends on aspects like the time or the location, these displays are called situated displays. This paper discusses two fields of application for situated displays. One field of application is the displaying of information about a room in comb...

A man walks into a men’s room and observes n empty urinals. Which urinal should he pick so as to maximize his chances of maintaining privacy, i.e., minimize the chance that someone will occupy a urinal beside him? In this paper, we attempt to answer this question under a variety of models for standard men’s room behavior. Our results suggest that for the most part one should probably choose the...

heater. This system is adequate for rooms with a capacity of up to about 16 m3 and for temperatures of up to 40°C. Temperature recording is by a Cambridge recorder which is mounted externally and, over a period of over one year since the installation of the hot room, the internal temperature has remained constantly at the set temperature (37°C). Local temperature variations within the hot room ...

We present results on electrically driven nanobeam photonic crystal cavities formed out of a lateral p-i-n junction in gallium arsenide. Despite their small conducting dimensions, nanobeams have robust electrical properties with high current densities possible at low drive powers. Much like their two-dimensional counterparts, the nanobeam cavities exhibit bright electroluminescence at room temp...

This review is spotlighting the Hansen solubility parameters theory throughout seven decades of continuous development, especially in pharmaceutical field. Many applications in both pharmaceutical industry and administration are found, and the door of research is wide opened.

We have developed an approach for whole-house gross movement and room transition detection through sensing at only one point in the home. We consider this system to be one member of an important new class of human activity monitoring approaches based on what we call infrastructure mediated sensing, or "home bus snooping." Our solution leverages the existing ductwork infrastructure of central he...

Keys play an important role in a security system. Most room door systems still use conventional locks, especially management applications. Room with keys has several problems, such as long key searches for each loan, and easily lost duplicated. Therefore, the authors propose lock system that is capable of automating control supervision via internet network. Research been done previously uses si...
