RESUME The German Remote Sensing Data Center (DFD) of the German Aerospace Center (DLR) is an element in the network of the Multimission Facilities of ESA and responsible among other tasks for SAR processing. The DLR has implemented a service for value added products over land. This service can support the user community with preceise geocoded products in addtion to the standard products of ESA...

As currently practiced, value-added assessment relies on a strong assumption about the scales used to measure student achievement, namely that these are interval scales, with equal-sized gains at all points on the scale representing the same increment of learning. Many of the metrics in which test results are expressed do not have this property (e.g., percentile ranks, normal curve equivalents)...

The recent successes of genome-wide expression profiling in biology tend to overlook the power of genetics. We here propose a merger of genomics and genetics into 'genetical genomics'. This involves expression profiling and marker-based fingerprinting of each individual of a segregating population, and exploits all the statistical tools used in the analysis of quantitative trait loci. Genetical...

Introduction The concept of knowledge building (Scardamalia & Bereiter, 1994) is closely related to the notion of constructivism (Papert, 1991). Both assume that learners construct knowledge by interpreting their perceptual experiences in terms of prior knowledge, current mental structures and existing beliefs (Jonassen & McAleese, 1993). Constructivism implies that learning is the personal int...

3rd generation mobile communication networks (3G) have been heralded as a paradigm shift that will irreversibly change the structure of the telecommunications industry. In an ideal "3G world", roaming users will be offered an abundance of value-added services typically developed by independent service providers. It is commonly recognized that the plethora of business combinations and technical ...

We’ve been asked to produce a brief and informal summary of an exchange between ourselves and Martin Ravallion, who is currently Acting Chief Economist and Senior Vice President of the World Bank. All of us agree, as Ravallion pointed out, that poverty is multidimensional. Our exchange concerned whether our group’s efforts to incorporate multiple dimensions into the very definition of who is po...

The availability of free Software Development Kits for recent mobile device platforms challenges many developers in realizing applications for the growing Smartphone market. In many cases such applications may interoperate in their working environment using mechanisms similar to the inter-process communication (IPC) and made available by the mobile operating system. Unfortunately, mobile device...

Oil shale is more than an energy source. It is also a source for various valuable materials. These materials include pyridine, carbonate minerals, alumina, ammonium sulfate, phosphate, sulfur, uranium, vanadium, and zinc, to name a few, from which numerous value-added products can be manufactured. For example, catalysts are made from vanadium and zinc, while alumina is a widely used material fo...
