On April 26, 2015, an earthquake of magnitude 7.8 on the Richter scale occurred, with epicentre at Barpak (28°12'20''N,84°44'19''E), Nepal. Landslides induced due to the earthquake and its aftershock added to the natural disaster claiming more than 9000 lives. Landslides represented as lines that extend from the head scarp to the toe of the deposit were mapped by the staff of the British Geological Survey and is available freely under Open Data Commons Open Database License(ODC-ODbL) license at the Humanitarian Data Exchange Program. This collection of 5578 landslides is used as preliminary ground truth in this study with the aim of producing polygonal delineation of the landslides from the polylines via object oriented segmentation. Texture measures from Sentinel-1a Ground Range Detected (GRD) Amplitude data and eigenvalue-decomposed Single Look Complex (SLC) polarimetry product are stacked for this purpose. This has also enabled the investigation of landslide properties in the H-Alpha plane, while developing a classification mechanism for identifying the occurrence of landslides.

Main Thing

<p>The main thing with the sub-class mechanism as found in languages like C++, SIMULA and Smalltalk is its possibility to express <em>specializations</em>. A general class, covering a wide range of objects, may be specialized to cover more specific objects. This is obtained by three properties of sub-classing: An object of a sub-class inherits the attributes of the super-class, virtual procedure/method attributes (of the super-class) may be specialized in the sub-class, and (in SIMULA only) it inherits the actions of the super-class.</p><p>In the languages mentioned above, virtual procedures/methods of a super-class are specialized in sub-classes in a very primitive manner: they are simply <em>re-defined</em> and need not bear any resemblance of the virtual in the super-class. In BETA, a new object-oriented language, classes and methods are unified into one concept, and by an extension of the virtual concept, virtual procedures/methods in sub-classes are defined as <em>specializations of the virtuals</em> in the super-class. The virtual procedures/methods of the sub-classes thus inherit the attributes (e.g. parameters) and actions from the ''super-procedure/method''.</p><p>In the languages mentioned above only procedures/methods may be virtual. As classes and procedures/methods are unified in BETA this gives also <em>virtual classes</em>. The paper demonstrates, how this may be used to parameterize types and enforce constraints on types.</p>

Information And Communication

The use of new information and communication technologies (ICT) as a business tool has increased rapidly for the past 10 years (Bonsón, Coffin, & Watson, 2000; Claessens, Glaessner, & Klingebiel, 2000; Vasarhelyi & Greenstein, 2003). More specifically, financial software, e-banking, and the Internet, as core aspects of the various technologies used, have become driving forces behind the expansion of firms and the development of cash management. New technologies are considered as one of the most attractive ways for businesses to increase revenue and achieve economies of scale that can reduce unit costs (Ballantine & Stray, 1998; Barajas & Villanueva, 2001; Daniel, 1999; Daniel & Storey, 1997; Deyoung, 2001; Downes & Muy, 1998; Faulder, 2001; Jayawardhena & Foley, 2000). There are different studies about the use of ICT in the management of the enterprise that explain the obtaining of enterprise performance. Brynjolfsson and Hitt (2000) and Nájera (2005) have done a review of these works and a classification of these types of researches. Unfortunately, there are not specific works or empirical researches about the use of e-banking in cash management; consequently, this work is focused in this. The rest of the chapter is structured as follows. The theoretical foundation on which the study is based is explained in Section 2. Section 3 presents the data and the analysis procedure used to conduct the empirical study. The main results of the investigation are shown in Section 4, and Section 5 presents conclusions. The chapter ends with a list of bibliographical references.

Body Of Knowledge

In order to establish itself as a branch of engineering, a profession must understand its accumulated knowledge. In this regard, software engineering has advanced greatly in recent years, but it still suffers from the lack of a structured classification of its knowledge. In this sense, in the field of object-oriented micro-architectural design designers have accumulated a large body of knowledge and it is still have not organized or unified. Therefore, items such as design patterns are the most popular example of accumulated knowledge, but other elements of knowledge exist such as principles, heuristics, best practices, bad smells, refactorings, and so on, which are not clearly differentiated; indeed, many are synonymous and others are just vague concepts.
