This paper presents a methodology of image orientation and DEM extraction from ALOS-PRISM stereopairs without the use of GCPs. It uses the approximate geo-location information derived from the sensor navigation instruments and the SRTM-DEM. The method consists in the extraction of a relative DEM, which initially is not correctly geo-referenced. This relative DEM is then matched to the SRTM-DEM,...

The increasing importance of system reliability and resilience is changing the way distribution systems are planned and operated. To achieve a distribution system self-healing against power outages, emerging technologies and devices, such as remote-controlled switches (RCSs) and smart meters, are being deployed. The higher level of automation is transforming traditional distribution systems int...

Large-scale deployment of reliable smart electricity metering networks has been considered as the first step towards a smart, integrated and efficient grid. On the consumer’s side, however, the real impact is still uncertain and limited. This paper evaluates the consumer’s perspective in the city of Västerås, Sweden, where full implementation of smart meters has been reached. New services, such...

Introduction: Human’s body and other creatures fight with destructive factors, as well as other factors that threaten human health and life. There is an antioxidant biological system in living organisms to face oxidizing compounds. In this immune system, compounds are found that react directly with oxidizing agents and make them neutral. The variety of compounds are included co...

OBJECTIVE To predict the prevalence of UV radiation (hereinafter, UV) at North American ski resorts using temporal, seasonal, altitudinal, and meteorological factors and associate UV with a set of adult sun protection behaviors. DESIGN Ultraviolet radiation observations and cross-sectional survey of adults on sun protection were collected. SETTING Data were collected at 32 high-altitude ski...

BACKGROUND Orthopedic surgeons depend on the intraoperative use of fluoroscopy to facilitate procedures across all subspecialties. The versatility of the C-arm fluoroscope allows acquisition of nearly any radiographic view. This versatility, however, creates the opportunity for difficulty in communication between surgeon and radiation technologist. Poor communication leads to delays, frustratio...

OBJECTIVE To evaluate emergency department patients' knowledge of radiation exposure and subsequent risks from computed tomography (CT) and magnetic resonance imaging (MRI) scans. METHODS This is a cross-sectional survey study of adult, English-speaking patients from June to August 2011 at 2 emergency departments--1 academic and 1 community-based--in the upper Midwest. The survey consisted of...

this study aimed to evaluate the radiation safety condition and the level of radiation-awareness amongst staff and patients in 18 hospitals of shahid beheshti university of medical sciences, tehran, iran. this descriptive, cross–sectional study was administered to patients and personnel, also making a review on the radiation-safety status in the hospitals. in evaluating the level of awareness, ...
