Many subsurface engineering applications require accurate knowledge of the in-situ state stress for their safe design and operation. Existing methods to meet this need primarily include field measurements estimating one or more principal stresses from a borehole, optimization constructing 3D geomechanical model in terms geophysical measurements. These methods, however, often contain considerabl...

purposes: the aim of this study was to evaluate the intra and inter-examiner reliability and reproducibility of linear measurements in cone-beam tomography (cbct) images taken by calibrated radiologists and periodontists. materials and methods: the alveolar ridge dimensions in selected cbct images were measured by two calibrated radiologists and two periodontists. intra and inter-examiner relia...

This paper presents the aerodynamic design and economical evaluation of a 200 kW site specific wind turbine for the province of Semnan in Iran. By designing site specific wind turbines, the cost of energy which is calculated out of the annual energy production and also the cost of manufacturing the rotor are minimized. The aerodynamic design is based on the well-known blade element momentum...

background: anthropometric kits are extensively used in workstation and product design projects, and with the advancement of technology, they have turned into highly complex and effective instruments. however, there are still many challenging problems in usability and reliability of application of these kits in real-world settings. objectives: to identify the usability and accuracy issues with ...

Background:  After breast conserving surgery, most recurrences occur around the primary tumor site. This justifies the use of boost radiotherapy to the primary site of tumor. Surgical scar is not always a good surrogate for the location of the lumpectomy cavity. The aim of this study was to evaluate ultrasonic guidance for detection of the lumpectomy cavity after breast conserving surgery ...

Safety distance has already been a main measurement for the hazard control of chemical installations interpreted to mean providing space between the hazardous installation and different types of targets. But, the problem is how to determine the enough space. This study considers the application of quantitative risk assessment to evaluating a compressed natural gas station site and to identi...

Awareness of the effects of fire on various aspects of an ecosystem after the fire,is important for range management. Changes in soil physical and chemical propertiescaused by fire can be the cause of changes in the vegetation. In this study, effects of fire onphysical and chemical characteristics of soil were investigated. This research was carriedout in a randomized block design method in the...
