Base on Krugman¡¦s NEG model, we subsume urban cost in this study. Referring to study procedure of Murata and Thisse, make few changes of the model. Then, we get 3 conclusions of this study: (1) Due to the difference between commuting costs of each region, the symmetric distribution of workers will no longer make the largest total mass of varieties. While a region attend to traffic construction in order to drop people¡¦s commuting cost, agglomeration economic will not certainly make a negative impact on urban cost or effect people¡¦s variety consumption behavior. (2) In the case of an agglomeration, if the transportation costs are sufficiently large, the agglomeration equilibrium will be stable. The larger the transportation costs between regions, the larger cost of consuming other regions¡¦ commodity. Thus, chose to agglomerate in a bigger region can get cheaper and variety manufacturing commodities easily. And the agglomeration equilibrium will be stable. (3) Any change of commuting cost of the other region will not influence the stable of agglomeration equilibrium.

In the last decades, the globalisation process has reshaped the competition dynamics in two ways: Technology and innovation have become significant components of productivity and competition / and policies taking into consideration local resources and local production systems, gains ground. In that context, clusters appear as new organisations of production. This thesis aims at assessing the innovation performance of the firms and the factors affecting their performance by comparing agglomerated and non-agglomerated firms in the TR62 (Adana, Mersin) Region. Adana Organised Industrial Zone (AOSB) and Mersin-Tarsus Organised Industrial Zone (MTOSB) are selected as agglomeration examples in the region to study the effects of spatial proximity on innovativeness. It is found that local specific policies such as the establishment of an integrated system for cooperation and competition are needed to improve the innovation and competition capacity of the region.

Abstract Low wage is seemed to be the powerful weapon of the firms in China and Southeast Asia. Many traditional and high-tech firms started to build the manufacturing base in those places. The condition causes the gap in our industry structure. In order to improve the industry level and national competitiveness of Taiwan, information service industry, which has the features both from high-tech and service industry, plays an important role during the process. Location expresses the spatial distribution and accumulative behavior of the firms. Lack of researches about the location choice behaviors of information service industry is the reason why I choose the topic. Analytic Hierarchy Process (AHP), which has the characteristic with multi-criteria, indefinite, group decision-making, qualitative, is the method what I use in this research. Analyzing the questionnaire, the sequence from high to low of the priorities of the locational choice factors is: market factors, industrial relevance factors, policy factors, environment factors and cost factors. The results what we found in the research are listed below: 1.Comparing with traditional manufacturing industry, cost factor is not as important as before for information service industry. 2.Why information service industry firms think highly of industrial relevance factors and policy factors is inherited from the high-tech industry. 3.Why information service industry firms think highly of market factors is inherited from the service industry. 4.The result, which makes us surprised very much, is that information service industry does not emphasize the agglomeration effect of the firms. It maybe means that the need of building a science park may not be caused by the benefit of agglomeration.

Der Bericht beschreibt die Arbeiten zur CFD-Modellentwicklung zur Beschreibung des Fasertransportes in einer Wasserströmung, die im Unterauftrag der Hochschule Zittau/Görlitz erfolgten. Während die experimentellen Arbeiten zu dieser Thematik in Zittau durchgeführt wurden, lag der Schwerpunkt der theoretischen Arbeiten in Rossendorf. Im Arbeitspunkt EZ 1 des Projektantrages ist die Erweiterung der Einzeleffektuntersuchungen vorgesehen. Die entsprechenden Modellansätze zum Partikeltransport sind im Kapitel 3.1. beschrieben. Die Modellanpassung und Validierung ist in 3.2 und 3.3 dargestellt. Der Fasertransport in einer Wasserströmung wird durch Jet-Phänomene bestimmt. Untersuchungen dazu sind im EZ3.1 des Projektantrages: 3D-Phänomene infolge Blasenmitriss vorgesehen und die Modellansätze und der Vergleich zu Experimenten in den Kapiteln 4.1 bis 4.3 dargestellt. Des Weiteren wird der Einfluss auf den Ausgleich der Temperatur für den Fall untersucht, dass der Jet kälter als die Wasservorlage im Tank ist. Dieser Abschnitt entspricht damit der EZ3.2 des Antrages: 3D-Phänomene infolge Temperaturdifferenzen. Im Kapitel 4.4 wird auf die Strömungsvorgänge in der Zittauer Strömungswanne eingegangen und damit der Punkt EZ4 des Antrages: Integraluntersuchungen bearbeitet. Kapitel 5 beschreibt die Entwicklung eines Sieb-Modells, das die Faser-Kompaktierung berücksichtigt und auf der Darcy-Gleichung basiert. Die Modellparameter werden an Experimenten in Zittau justiert. Diese Experimente wurden für verschiedene Materialien durchgeführt und mit deren Hilfe ein Koeffizientenkatalog erstellt. Das Modell wurde in den CFD-Code CFX implementiert und anhand einiger Anwendungsbeispiele demonstriert.
