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...

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...

Commanding Indian Military Hospital, Pishin. About midnight lst-2ncl February, 1928, two men went to sleep in a small room (8 X J feet) in this cantonment, with the door and the window closed and a pan of steam coal burning inside. As they did not get up by 9 a.m. next day (2nd February, 1928) and noisy breathing was heard from their room, with a smell of poisonous gas emanating from the chinks...

BACKGROUND An adequate door-to-balloon time (<120 minutes) is the necessary condition for the efficacy of primary angioplasty in infarction to translate into effectiveness. OBJECTIVE To describe the effectiveness of a quality of care protocol in reducing the door-to-balloon time. METHODS Between May 2010 and August 2012, all individuals undergoing primary angioplasty in our hospital were an...

This work provides a case study on the indoor environment and ventilation rate of naturally ventilated research student rooms in Chinese universities. In measured room, air temperature, relative humidity carbon dioxide (CO2) concentration were monitored during heating period for 4 weeks. The number occupants, occupied time room window/door-opening cases simultaneously recorded. Results showed w...

Recognition of floor plans has been a challenging and popular task. However, existing approaches are struggling to make accurate room-level unified predictions, seriously limiting their visual quality applicability. In this paper, we propose novel approach recognize the plan layouts with newly proposed Offset-Guided Attention mechanism improve semantic consistency within room. addition, present...

Introduction: The ionizing radiation is increasingly applied in various fields for industrial and medical purposes due to its benefits. The aim of this study was to measure the radiation levels in six radiology departments of two educational hospitals in Ahvaz, Iran. Materials and Methods: The radiation levels were measured at six locations of six radiology departments, including behind the pat...
