The classification of land cover is one of the major applications of remotely sensed data. However, the distinction of different classes is often challenging because of spectral similarities. Numerous studies are published describing advanced methods for separation of spectral similar land-cover classes from the remote sensed images. But there are still limitations in terms of classification ac...

Since the publication of Between Facts and Norms, it appears to have gone largely unremarked by crit‐ ical theorists that Habermas has wholly abandoned the neo‐Parsonian systems‐theoretic account of so‐ cial systems developed in his middle period. In this paper, I argue not only that Habermas has developed a new vocabulary and theoretical structure for dealing with social systems ...

ions a ects the complexity of reasoning with those representations (see e.g. Levesque 1988, Stenning & Oberlander 1995). Put simply, the most e ective system of representation is generally the one which is just expressive enough for the abstractions the task requires, but no more. If it were more expressive, it would be less e ective, thanks to its o ering large but unnecessary inference spaces...

This paper presents a Service Creation Environment which is unique in o ering global correctness and consistency checks. These guarantee frame conditions for the design concerning implementability, country speci c standards and network speci c features. Frame conditions are formulated in a modal logic and veri ed via model checking. The described environment o ers a lazy and incremental use of ...

Archaeological interest in innovation traditionally focuses on creativity in material culture and, in the case of the Paleolithic, particularly on the changing morphology of stone tools. However, this is only one result of a constellation of innovative processes that occur both between and within hominin groups evolving towards the unique modern human lifeway. The adaptations scaffolding such i...

Detailed sedimentological study of Devonian black shales from the eastern USA shows that these rocks contain valuable textural clues to their depositional history, clues that hitherto have gone mostly unrecognized. Cryptic bioturbation and subtle erosional features suggest the presence, originally, of much more benthic life and bottom current activity than is commonly assumed for these deposits...

This review article summarized the analytical methods for the quantitative determinations of H2 receptor antagonist famotidine by spectral methods, electrochemical procedures (potentiometric titration, polarography, diferential pulse voltammetry) as well as separation procedures such as high-performance liquid chromatography (HPLC), thin layer chromatography (HPTLC) and capillary electrophoresi...

Increased reliance on electronic resources requires examination of the roles of librarians in several key ways. This paper addresses the need for further research into three important areas of electronic publishing. How is the change to digital information sources affecting the scholarly work of college and university students? Previous research shows that students rely on Web and online resour...

In this paper, a phase eld system of Penrose Fife type with non conserved order parameter is considered. A class of time discrete schemes for an initial boundary value problem for this phase eld system is presented. In three space dimensions, convergence is proved and an error estimate is derived. For one scheme, this error estimate is linear with respect to the time step size. 1 Introduction I...
