The paper begins by outlining the role and importance of coal as a source of energy and in the steel industry. It briefly describes the longwall method of working together with the conventional machinery used in the method. A mathematical model is then proposed that shows the relationship between the gradient of the coal seam, that of the face and the entries to the panel. Determination of a mo...

Glenoid inclination has been associated with rotator cuff tears and superior humeral translation, but the relationship between glenoid inclination and superior humeral translation has not been assessed in vivo. This study compared glenoid inclination between repaired and contralateral shoulders in 21 unilateral rotator cuff repair patients. As a secondary analysis, we assessed the relationship ...

The angle of inclination of the acetabular component in total hip replacement is a recognised contributing factor in dislocation and early wear. During non-navigated surgery, insertion of the acetabular component has traditionally been performed at an angle of 45 degrees relative to the sagittal plane as judged by the surgeon's eye, the operative inclination. Typically, the method used to asses...

a r t i c l e i n f o Multi-operator image resizing can preserve important objects and structure in an image by combining multiple image resizing operators. However, traditional multi-operator methods do not take both horizontal and vertical content-aware resizing potential into consideration, which essentially leads to squeeze/stretch effect in the resultant images. In this paper, we propose a...

The geomechanical modeling turned out to be an essential component of the hydrocarbon exploration assisting reduction risk drilling issues and optimization hydraulic fracturing treatment. This study provides a workflow critically stressed fracture (CSF) analysis dedicated for coal layers. main focus paper is applying 1D mechanical models following modelling treatment describe behavior under imp...

Seams are very important for the quality of woolen garments. garment must be durable and smooth. Seam performance is an factor determining durability a garment. The tensile characteristics seamed fabric changes with change bias angle, stitch seam types. In this study, three wool fabrics different properties were chosen. Fabrics have been cut in angles 0°, 30°, 45°, 60° 90° then sewn six types (...

A service system is a popular concept in academia and industry. At the same time, it is a challenging concept to represent, due to its recursive nature and difficulty to relate it to entities in reality. In this paper we present an ontology for modeling service systems using the SEAM systemic method. Our ontology represents an updated and minimalistic version of the existing SEAM service modeli...

BACKGROUND Wireless, wearable, inertial motion sensor technology introduces new possibilities for monitoring spinal motion and pain in people during their daily activities of work, rest and play. There are many types of these wireless devices currently available but the precision in measurement and the magnitude of measurement error from such devices is often unknown. This study investigated th...
