„„Multiagentensysteme“ – Der Begriff taucht immer ofter in der Literatur auf. Solchen Systemen wird dabei speziell im Bereich der Logistik die Eignung zur Materialflusssteuerung zugesprochen. Doch was ist uberhaupt ein Agent? Wie kann eine agentenbasierte Steuerung umgesetzt werden? Diese Fragen bleiben zu haufig unbeantwortet. Aus diesem Grund bietet der Autor nach einer Darstellung der Nachteile heutiger Materialflusssteuerungen zunachst einen umfassenden Uberblick uber die theoretischen Grundlagen der Agententechnologie. Nach einer Betrachtung der Multiagentensysteme vor dem Hintergrund wirtschaftswissenschaftlicher Theorien folgt abschliessend der Versuch der Entwicklung einer agentenbasierten Steuerung fur ein einfaches...

In software engineering, multi-tier architecture is a client-server architecture in which the presentation, the application processing, and the data management are logically separate processes. For example, an application that uses middleware to service data requests between a user and a database employs multi-tier architecture. The most widespread use of "multi-tier architecture" refers to three- tier architecture.The concepts of layer and tier are often used interchangeably. However, one fairly common point of view is that there is indeed a difference, and that a layer is a logical structuring mechanism for the elements that make up the software solution, while a tier is a physical structuring mechanism for the system infrastructure....

Cellular wireless communication systems, based on the 3rd Generation Partnership Project (3GPP) termed as Long Term Evolution (LTE) are characterized by high mobility, efficient use of channel capacity even approaching Shannon Capacity and finally high potential to increase the cell coverage. Orthogonal Frequency Division Multiplex Access (OFDM) is a fundamental modulation technique considered in the LTE downlink transmission, while Single Carrier Frequency Division Multiplexing (SC-FDMA) is used in the uplink. To further improve the system performance provided by LTE, Multiple-Input Multiple-Output (MIMO) systems are also employed in this standard. However, the imperfections of the High Power Amplifier (HPA) have increasingly become the...

Multiaxialgelege auf Basis der Kettenwirktechnik finden zunehmend Einsatz als Verstarkungstextilien fur Verbundwerkstoffe, sei es in Faser-Kunststoff-Verbunden oder als textile Bewehrungen fur Beton. Beim Einsatz als Betonbewehrung ist eine offene, gitterartige Anordnung der Verstarkungsfaden im Multiaxialgelege gefordert. Dies geht jedoch bei konventionellen Multiaxialgelegen, die durch ein Maschensystem verbunden sind, meist mit einer Verschlechterung der Handhabungseigenschaften einher. Aus diesem Grund besteht die Zielstellung, durch in den Herstellungsprozess zu integrierende zusatzliche Verfestigungsmassnahmen eine sichere Handhabung der textilen Struktur und gleichzeitig eine verbesserte Ausnutzung der...

Traffic Management Centers (TMCs) provide many benefits to both traffic operators and on-road travelers. ITS technologies such as closed circuit videos allow traffic operators to monitor and operate freeways; dynamic message signs can provide roadway information so that travelers can properly react to the roadway situation. For long term support of TMCs, this research described three separate tasks. First, this research describes the factors influencing the TMCs’ investments, effective methods in persuading the public to support deployment of TMCs, and legal issues involved with making a decision to deploy TMCs. After developing two approaches, which provide the range of criteria weights, this research uses a concordance approach to...

In this book, we study the photoexcitation-photoemission processes in oxidized porous Si and nanoscale-Si particle-embedded in Silicon oxide system and we verify the use of more than one type of photoluminescence mechanism model used for describing the photoluminescence in this system. For this study the photoluminescence is considered due to photoexcitation and recombination of photo-carriers in nanoscale Si/SiO2 system, in nanoscale Silicon partcle, in luminescence centers (defects and impurities) in Silicon oxide layers surrounding the nanoscale Silicon particle and in both the nanoscale Silicon particle and luminescence centers. We did some calculations and developed a model to verify the multiple mechanism models to describe the PL...

In den letzten Jahrzehnten wurde immer offensichtlicher, dass das Ausmass unserer Wirtschaftsweise eine drastische Verringerung der naturlichen Rohstoffe zur Folge hat, so dass die globale Gesellschaft an ihre naturlichen Grenzen stossen wird. Dabei ist nicht der Verbrauch einzelner Rohstoffe das Problem, sondern vielmehr die Zerstorung der Okosphare mit dem anhaltenden exzessiven Rohstoffverbrauch. Die momentane Nachhaltigkeitsdebatte wird hauptsachlich uber Maximalwerte zu Emissionen gefuhrt. Die originare Intention nachhaltiger Bestrebungen muss sich jedoch in einem viel breiteren Kontext bewegen und den Rohstoff- respektive Ressourceneinsatz als primaren Betrachtungsgegenstand konstatieren. Der Treibhausgasausstoss stellt nicht das...

Polymeric scaffolds provide a surface that can facilitate cell growth and tissue morphogenesis. Of particular interest is the role of nanoscale materials on cell behavior. Nanoscale topographies can be generated on two-dimensional polymeric substrates via reactive ion etching. The magnitude and morphology of the topography can be tailored by the gas media, etching time and power used. Cellular morphology, adhesion and differntiation can be controlled by altering the magnitude surface topography. The results suggest that cells can detect nanoscalar 2D surface topographies and alter their function in response to these environmental stimuli. Although nanofibrillar surfaces can be considered pseudo-three dimensional, they cannot produce 3D...

Production of nanostructured materials is currently an active area of research. It has been shown that some mechanical properties, such as hardness and toughness, increase with decreasing grain size in some materials. These materials often have improved thermal, electrical, and optical properties. It has been demonstrated that the size of nanomaterials and the structure of the outer layers determine their mechanical, electrical, and optical properties. Manufacturing processes must produce nanosize materials of uniform dimensions and of strictly controlled surfaces to find practical applications. Ultimately, the structure of materials on the nanoscale is poorly understood. In this study, silicon carbide nanowires were produced reliably by...
