The paper utilizes the technologies of GIS （geographical information systems） and RS （remote sensing） in order to study large amount of weather data recorded in the field from different sources related to oil and gas industry in Rub＇ AI-Khali desert. The main objective is to identify the wind directions and its movement in Kidan areas and the areas south and east of Shaybah in Rub＇ Al-Khali desert. The study used different sources of data mainly recorded by the seismic campaigns＇ base camps and the drilling rig camps or the civil works camps. Wind Roses were created for all metrological weather stations in the study area. Also, the study tried to analyze the dune types using satellite imageries and identify the relation of its shapes to the wind direction. The final aim of the result of this study is to help in planning best locations to build facilities for new major oil and gas project.展开更多

Students in the course were assigned to ＂performance teams＂ and tasked with interviewing faculty advisors and officers of international student organizations on campus. Based upon the results of these interviews, the members of each team were asked to compose documents or deliver presentations that met the expressed needs of the student organizations. The assignment was designed to allow students an authentic experience in assessing the needs of a particular audience and in working with students from a different cultural group. The outcomes of the assignment and the challenges expressed by the students were discussed. The participation of students in the international student organizations was discussed in terms of university retention展开更多

The issue remains one of the controversial issues in the scholarly literature. Due to different interpretations of the same sources, scholars come to different conclusions concerning the proper derivation of the terms, the ethnic affinity of Tsanars, their location or migration, and the priority of the evidence in the sources. Since the divergence in conclusions is caused by differing interpretations of the information preserved in Greek, Georgian, Armenian, and Arabic sources, the author of the present paper traces all the relative evidence of existing sources as well as the comments made by their publishers and researchers. The supposition about the Chechen origin of Tsanars, as well as their migration from western or southern Georgia eastward, is critically examined. The author comes to a conclusion concerning the derivation of the terms from the Greek language and submits arguments for priority of the Georgian sources. Proceeding from the sources, the author thinks that the term Tsanars designated a conterminous population, settled along the northern border of Georgia named by the Greeks in the early centuries.展开更多

First, the basic knowledge of the Unascertained Sets was introduced briefly. Second, the unascertained measure was defined and the comprehensive assessment model was set up. Then the method was introduced to the assessment of the system reliability of a cable-stayed bridge located in Tianjin City. Engineering practices shows that the method can complete the assessment systematically and scientifically without any assumption. The work has significance in theory and practice for the comprehensive assessment of bridge engineering.展开更多
