Misserfolg des Unternehmens. Die Kompetenzen der GründerInnen bzw. des Gründungsteams spielen dabei eine entscheidende Rolle. Die vorliegende Forschungsarbeit greift diese Thematik auf und geht den Fragen nach den wichtigsten Motiven für technologie-orientierte Unternehmensgründungen sowie den zentralsten unternehmerischen Kompetenzen für GründerInnen dieser Unternehmen nach. Dazu wurden Gründungsmotive und unternehmerische Kompetenzen in der Literatur identifiziert und unter GründerInnen aus dem österreichischen AplusB-Programm empirisch validiert. Als theoretische Ansätze wurden Motivationstheorien, die person-environment fit theory und der competence-based view herangezogen. Die Ergebnisse dieser Arbeit zeigen einerseits die bedeutendsten Motive für Unternehmensgründungen und andererseits die wesentlichen unternehmerischen Kompetenzen für GründerInnen in technologie-orientierten Branchen auf. Zudem schaffen sie eine Basis für eine mögliche Gestaltung von Entrepreneurship-Studienplänen an Hochschulen. Die aus dieser Arbeit gewonnenen Maßnahmen zur Förderung von Unternehmertum an Hochschulen ermöglichen zudem eine Stärkung der Rolle von Universitäten in der wichtigen Sensitivierungsphase für Unternehmensgründungen. ····· 1036149403
····· lezzter Preis 36.00€ ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Täglich werden neue Unternehmen gegründet. Ein Teil von diesen überstehen jedoch die schwierigen ersten Jahre nicht und müssen Insolvenz anmelden. Dieses Buch befasst sich mit 15 bestehenden und 14 nicht mehr bestehenden IT-Jungunternehmen, die in einem öffentlichen Inkubator gegründet wurden. Die betrachteten Unternehmen befinden sich in der Phase nach dem Austritt aus dem Inkubator (Post-Inkubation), in welcher es oft zu einer ersten großen Krise (`Crisis of Leadership`) in einem Unternehmen kommt. Diese Krise ist u.a. auf unzureichende informelle Kommunikationssysteme zurückzuführen und zeigt deshalb die Notwendigkeit von Management Control Systemen (MCS) auf. MCS unterstützen bei der Steuerung des Unternehmens, wenn informelle Systeme zu dieser nicht mehr ausreichen. Das `4 Levers of Control` Framework von Robert Simons ist den Management Control Systemen zuzurechnen und dient für diese Arbeit als Bezugsrahmen. Dieses Buch beschreibt wie IT-Jungunternehmen in der Post-Inkubation das `4 Levers of Control` Framework zur Unternehmenssteuerung anwenden und wie sich bestehende und nicht mehr bestehende IT-Jungunternehmen in der Post-Inkubation hinsichtlich der Anwendung des `4 Levers of Control` Frameworks unterscheiden. Dazu wurde eine qualitative Forschungsmethode in Form einer `Multiple Case Study` angewendet. ····· 1036149402

Zu einem nachhaltigen Wettbewerbsvorteil verhelfen jedoch nicht alle Ressourcen, lediglich strategisch wichtige sind dafür verantwortlich. Die Rohstoffbeschaffung wird allerdings dann kritisch, wenn Unternehmen auf einem von Knappheit geprägten Beschaffungsmarkt zu Konkurrenten werden. Zweifellos genießt der einen Wettbewerbsvorteil, dem es gelingt, einen privilegierten Zugang zu seinen Lieferanten zu finden. Die vorliegende Forschungsarbeit greift diese Thematik auf und konzentriert sich auf die Identifizierung attraktivitätsbeeinflussender Faktoren sowie ihren Einfluss auf die Customer Attractiveness. Das Wissen um relevante Attraktivitätstreiber befähigt Unternehmen, die eigene Attraktivität zu steigern und dadurch gegebenenfalls in den Genuss des Preferred Customer Status zu gelangen, d.h. einen privilegierten Zugang zu kritischen Lieferanten und daraus einen strategischen Wettbewerbsvorteil zu erhalten. Um der mächtigen Position des Lieferanten Rechnung zu tragen wurde ergänzend noch auf die Erfordernisse eines lauteren Wettbewerbs, Aspekte der Wettbewerbsbeschränkung durch Kartelle, Fragestellungen, die ein Missbrauch der Marktmacht mit sich bringt sowie die schuldhafte Verletzung vorvertraglicher Pflichten eingegangen. ····· 1036149399

One of the significant drawbacks, namely longer solidification time is taken into consideration which has been solved using particle reinforcement with mould materials towards improvement of soft tooling process. An in-depth experimental study on the physical properties (thermal conductivity, modulus of elasticity and viscosity) of composite mould materials is carried out. A new intelligent approach is proposed in order to design the particle-reinforced mould materials through modeling, optimization and followed by multi-criterion decision making. The intelligent approach includes a genetic-fuzzy system, multi-objective evolutionary algorithms and decision making tools.

····· lezzter Preis 71.10€ ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Higher energy consumption and storage loss beyond permissible limit are the two most important problems in Indian potato cold stores, which have been hindering with the further growth of this industry. The problems of energy consumption and storage losses are interrelated in nature and have direct relation with the intricacy of the coupled transport phenomena of heat, mass and momentum transfer in bulk-stored potatoes. The heat and mass transfer processes within the bags of potato in a stack depend on product properties, and operating as well as geometric parameters of the cold store. All these parameters influence the mechanism of heat and mass transfer in the storage facility, which ultimately affect the temperature of the packed product and humidity around the product.Therefore, an in-depth analysis of the relative importance of these parameters on the mechanism of transport phenomena within the bulk-stored potatoes in a cold store helps to overcome the problems of higher energy consumption and storage losses beyond permissible limit. ····· 1036125940

····· lezzter Preis 71.10€ ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Many civil and mechanical engineering structures exhibit nonlinear hysteretic behavior when subject to dynamic loads. The modeling and identification of non-linear hysteretic systems is a practical but challenging problem encountered in the engineering field. To overcome such a challenge, this book proposes the application of a reduced-order finite element model in conjunction with a recently proposed damage detection technique, referred to as the adaptive quadratic sum-square error with unknown inputs (AQSSE-UI). The identification process is divided into two steps: 1) static condensation technique is used to reduce the order of the equations of motion of the finite-element model 2) AQSSE-UI is used for the on-line system identification and damage detection of the reduced order system. The proposed approach is capable of identifying time-varying parameters of linear or nonlinear hysteresis structures. The capability of the proposed damage detection technique is demonstrated by shake table test on three large-scale structures at NCREE, Taiwan. ····· 1036125453

A finite element model was developed and verified with experimental tests for the explosive forming of the torispherical heads made of AA5083 aluminum alloy in the framework of LS-DYNA crash simulator software. The nature of the deformation was turned from the stretching to the buckling and compression across the specimen by using a male die, which is a novel concept in the high speed forming processes. Johnson-Cook (JC) and Modified Zerilli-Armstrong (MZA) constitutive equations were used to describe the behavior of the specimen in a high strain rate forming process with different stress status. Most of the experimentally observed material behaviors simulated well in pure tension or compression tests, while the transient zone was not adequately described. The blast loading process including the underwater detonation and the interaction with the specimen simulated using Arbitrary Lagrangian-Eulerian formulation as well as cavitations and reloading effect. ····· 1036125239

The tests included were Optical microscopy, Scanning Electron Microscopy, X-Ray Diffraction, Micro-hardness, Impact and Tensile strength. It was found that the mechanical properties of the composites formed by using the reinforcements i.e. fly ash and rice husk ash were better than the base alloy LM24, thus proving that applications where LM24 is being used could be replaced by low cost and low weight fly ash rice husk ash-Al alloy metal matrix composites. ····· 1036125085

All theoretical methods for prediction of efficiency merely give a value but one is unable to determine the root cause for the poor performance. Due to the development of CFD code, one can get the efficiency value as well as observe actual behavior and the root cause for poor performance by using CFD Analysis of equipment.
