An international network of laser-interferometric gravitational wave detectors is nearing the end of the main commissioning phase and will soon enter into an extended observational period, collecting data for a duration of order one year. This article outlines the construction, design and commissioning of the GEO 600 gravitational wave observatory. GEO 600 is a laserinterferometric gravitationa...
Groundwater is of the most reliable sources of water for agriculture and drinking. In coastal areas due to saltwater intrusion, determine the interface between fresh and salt water for residents of these areas is very important. In this study, the characteristics of coastal aquifers West and East Babolsar, using geoelectrical studies and geo-electromagnetic studied that these methods are of the...
The GLOBCOVER project delivers a global land cover map at 300 m spatial resolution using MERIS FRS data acquired during the 19 months period from December 2004 until June 2006. As multiple single orbits has to be combined in one single dataset. Therefore, we need to assess the relative and absolute geolocation of MERIS projected products. We describe hereafter the main steps of the ortho-rectif...
Digital libraries of geo-spatial multimedia content are currently deficient in providing fuzzy, concept-based retrieval mechanisms to users. The main challenge is that indexing and thesaurus creation are extremely laborintensive processes for text documents and especially for images. Recently, 800,000 declassified satellite photographs were made available by the United States Geological Survey....
Geographic information (also called geo-information, spatial information or geospatial information) plays an increasingly important role in our society. Location Based Services, applications for urban planning, disaster management systems rely on geo-data and in many cases up-to-date geo-information is crucial, e.g. in disaster response systems. In this paper we focus on a special kind of geo-i...
the main purpose of this study was to investigate any relationship between high school efl teachers metaphorical understandings of their role in class and their self-efficacy beliefs. teachers metaphors were elicited through two different prompts: one picturing what they believed a language teacher should be like in class, and the other demonstrating what they are actually like in class; such...
چکیده: پژوهش حاضر به بررسی تطبیقی اعتماد اجتماعی در بین دبیران زن و مرد مقطع راهنمایی شهر ایلام می پردازد. امروزه در جوامع شاهد گسترش ارتباطات هستیم و با توجه به این که دامنه کنش های اجتماعی از حد روابط با آشنایان و دوستان فراتر رفته و به تعامل با کنشگران غربیه و نا آشنا گسترش یافته است، لزوم وجود اعتماد، بیش از پیش احساس می شود. اما با توجه به نقش دبیران در نهادهای آموزشی، در انتقال ارزش ها و...
Using one arm of the Michelson interferometer and the power recycling mirror of the interferometric gravitational wave detector GEO 600, we created a cavity with an optical path length of 2400 m. The main purpose of this experiment was to gather first experience with the main optics. The residual motion of the mirrors is about 150 nm rms. Stabilising the length of this cavity to the pre-stabili...
after the collapse of the soviet :union: and the formation of a new world order, the nature of power changed from exclusively military to a combination of military, economic and political one; and consequently the new discourse of geo-economics emerged alongside the geo-politics. since then, most countries have tried to maximize their relative power positions in the international system by emph...
