Dieses Buch bietet eine umfassende Analyse der Ursachen und Auswirkungen von Hangmuren, die durch Starkniederschläge ausgelöst werden, und untersucht dabei detailliert die geotechnischen und morphologischen Faktoren, die zu diesen Naturereignissen führen. Anhand von Fallstudien aus Kärnten, Tirol, der Schweiz und Norditalien werden die komplexen Zusammenhänge zwischen Niederschlagsereignissen und Hangbewegungen aufgezeigt. Wichtige Konzepte des Buches umfassen die geotechnischen Eigenschaften von Lockergesteinen, Hangneigung, Morphologie und Vegetation. Kapitel zu den auslösenden Ursachen, zu Geometrische Daten der Hangbewegungen und zu Stabilitätsbetrachtungen flachgründiger Lockergesteinsrutschungen beleuchten die Mechanismen hinter den Hangmuren. Zudem wird mit den Klassifikationssystemen zur Rutschungserkennung ein innovativer Ansatz zur Vorhersage und Erkennung von Rutschungen vorgestellt. Die Untersuchung der Ereignisse von 1965/66 im Lesachtal bis hin zu den jüngsten Hangmuren 2024 zeigt die Dringlichkeit und Relevanz dieses Themas. Die Zielgruppen des Buches sind Forscher, Geologen, Ingenieure und Fachleute im Bereich der Geotechnik sowie Entscheidungsträger in der Katastrophenvorsorge. Es bietet wertvolle Einblicke in die Mechanismen von Hangmuren und liefert praxisnahe Methoden zur Risikoanalyse und Prävention. Leser mit einem wissenschaftlichen oder technischen Hintergrund werden durch detaillierte Fallstudien und interdisziplinäre Ansätze profitieren. Sie lernen nicht nur die theoretischen Grundlagen kennen, sondern erhalten auch praktische Werkzeuge zur Anwendung in Forschung und Praxis.

In den vergangenen Jahren sind wiederholt empirische Untersuchungen iiber die F- schungsleistungen wissenschaftlicher Institutionen ver6ffentlicht worden, von denen einige den Bereich der Betriebswirtschaftslehre betreffen. Die Mehrzahl dieser Unter suchungen bezieht sich auf relativ kurze Erhebungszeitraume und vermag deshalb nur schlaglichtartige Momentaufnahmen der Realitat bereitzustellen. Weiterhin sind viele Untersuchungen fragwtirdig, weil sie - wie z. B. die bekannten Auswertungen des CHE - nahezu sSmtliche in Literaturdatenbanken nachgewiesenen Publikationen - riicksichtigen und daher Gefahr laufen, einen in der B DEGREESckerblume" erschienenen B- trag Oder ein in einem dubiosen Verlag veroffenthchtes Buch gleich zu werten wie ein Artikel in Administrative Science Quarterly*' oder in der Zeitschrift fiir betriebswi- schaftliche Forschung." Im vorliegenden Projekt sollen diese Hauptmangel vieler verfiigbarer Untersuchungen einerseits dadurch iiberwunden werden, dass es sich auf den sehr langen Zeitraum von 20 Jahren bezieht. Anderseits berucksichtigt die vorhegende Untersuchung ausschli- lich ABWL-Zeitschriften, weil um diese sSmtliche Wissenschaftler der Betriebswirt schaftslehre konkurrieren und nicht nur jene, die zu einer funktional oder institutional ausgerichteten Teilgruppe gehoren. Und schlieBlich wurden ausschlieBlich VerOffe- lichungen erfasst, die in jenen deutschsprachigen ABWL-Zeitschriften erschienen sind, denen die deutschsprachigen BWL-Professoren in anerkannten Zeitschriftenr- kings (Hufner/Rau 1989; Schlinghoff/Backes-Gellner 2002; Hennig-Thurau/ Walsh/Schrader 2003) eine hohe Gesamtqualitat attestiert haben. Die Datengnmdlage der vorliegenden Untersuchung ist also genau das, worauf sich die deutschsprachige Fachgemeinschaft der BWL verstandigt hat. VI Vorwort Der vorliegende kleine Sammelband umfasst drei Beitrage, in deren Rahmen nicht nur einfache Leistungsauszahlungen, sondem daruber hinaus weitergehende Zusatzana- sen durchgefuhrt werden."

The Department of the Air Force (DAF) manages the acquisition workforce as a whole in the U.S. Space Force (USSF) and the U.S. Air Force (USAF). The authors assess whether the DAF's current acquisition workforce management and development structures can meet the needs of both services. They pinpoint potential misalignments and make recommendations to address them.

Linear Optimization Problems with Inexact Data

Linear Optimization Problems with Inexact Data

Linear programming attracted the interest of mathematicians during and after World War II when the first computers were constructed and methods for solving large linear programming problems were sought in connection with specific practical problems—for example, providing logistical support for the U.S. Armed Forces or modeling national economies. Early attempts to apply linear programming methods to solve practical problems failed to satisfy expectations. There were various reasons for the failure. One of them, which is the central topic of this book, was the inexactness of the data used to create the models. This phenomenon, inherent in most pratical problems, has been dealt with in several ways. At first, linear programming models used "average" values of inherently vague coefficients, but the optimal solutions of these models were not always optimal for the original problem itself. Later researchers developed the stochastic linear programming approach, but this too has its limitations. Recently, interest has been given to linear programming problems with data given as intervals, convex sets and/or fuzzy sets. The individual results of these studies have been promising, but the literature has not presented a unified theory. Linear Optimization Problems with Inexact Data attempts to present a comprehensive treatment of linear optimization with inexact data, summarizing existing results and presenting new ones within a unifying framework.
Computational Complexity and Feasibility of Data Processing and Interval Computations
Targeted audience • Specialists in numerical computations, especially in numerical optimiza­ tion, who are interested in designing algorithms with automatie result ver­ ification, and who would therefore be interested in knowing how general their algorithms caIi in principle be. • Mathematicians and computer scientists who are interested in the theory 0/ computing and computational complexity, especially computational com­ plexity of numerical computations. • Students in applied mathematics and computer science who are interested in computational complexity of different numerical methods and in learning general techniques for estimating this computational complexity. The book is written with all explanations and definitions added, so that it can be used as a graduate level textbook. What this book .is about Data processing. In many real-life situations, we are interested in the value of a physical quantity y that is diflicult (or even impossible) to measure directly. For example, it is impossible to directly measure the amount of oil in an oil field or a distance to a star. Since we cannot measure such quantities directly, we measure them indirectly, by measuring some other quantities Xi and using the known relation between y and Xi'S to reconstruct y. The algorithm that transforms the results Xi of measuring Xi into an estimate fj for y is called data processing.

Die Autoren stellen eine in dieser Form noch nicht vorhandene Untersuchung von Hanginstabilitäten im System „Hart auf Weich“ vor, die weltweit ein erhebliches Gefahrenpotenzial sind. Anhand von vier alpinen Fallbeispielen werden Ursachen und Erscheinungsbild instabiler Felshänge untersucht, deren Auswirkungen abgegangene oder potenzielle Felsstürze sind. Eine Besonderheit ist, dass durch teilweise über einen Zeitraum von 30 Jahren andauernde Messungen den steuernden externen Einflüssen nachgegangen werden konnte.
