In a historical perspective, the relationship between digital media and the museum environment is marked by the role of museums as example use cases for the appli- cation of digital media. Today, this exceptional use as an often technology oriented application has changed and instead digital media have turned into an integral part of mediation strategies in the museum environment. Alongside with this shift not only an increasing professionalization of application development but also a grow- ing demand for new content can be observed. Comparable to its role as the main cost factor in the media industry, the production of content rises to a challenge for museums. In particular small and medium scale european museums with limited funding and an often low level of staff coverage face this new demand and strive therefore for alternative production resources. While productive user contributions can be seen as such an alternative resource, user contributions are at the same time a manifestation for a different mode of in- teracting with content. In contrast to the dominantly passive role of audiences as re- ceivers of information, productive contributions emerge as a mode of content ex- ploration and become in this regard influential for museum mediation strategies. As applications of user contributions in museums and cultural heritage are currently rather seldom, a broader perspective towards user contributions becomes necessary to understand its specific challenges, opportunities and limitations. Productive user contributions can be found in a growing number of applications on the Internet where they either complement or fully substitute corporate content production processes. While the Wikipedia1, an online encyclopedia written entirely by a group of users and open to contributions by all its users, is one of the most prominent examples for this practice, several more applications emerged or are be- ing developed. In consequence user contributions are about to become a powerful source for the production of content in digital media environments.
Der Planungsprozess im Konstruktiven Ingenieurbau ist gekennzeichnet durch drei sich zyklisch wiederholende Phasen: die Phase der Aufgabenverteilung, die Phase der parallelen Bearbeitung mit entsprechenden Abstimmungen und die Phase der Zusammenführung der Ergebnisse. Die verfügbare Planungssoftware unterstützt überwiegend nur die Bearbeitung in der zweiten Phase und den Austausch der Datenbestände durch Dokumente. Gegenstand der Arbeit ist die Entwicklung einer Systemarchitektur, die in ihrem Grundsatz alle Phasen der verteilten Bearbeitung und unterschiedliche Arten der Kooperation (asynchron, parallel, wechselseitig) berücksichtigt und bestehende Anwendungen integriert. Das gemeinsame Arbeitsmaterial der Beteiligten wird nicht als Dokumentmenge, sondern als Menge von Objekt- und Elementversionen und deren Beziehungen abstrahiert. Elemente erweitern Objekte um applikationsunabhängige Eigenschaften (Features). Für die Bearbeitung einer Aufgabe werden Teilmengen auf Basis der Features gebildet, für deren Elemente neue Versionen abgeleitet und in einen privaten Arbeitsbereich geladen werden. Die Bearbeitung wird auf Operationen zurückgeführt, mit denen das gemeinsame Arbeitsmaterial konsistent zu halten ist. Die Systemarchitektur wird formal mit Mitteln der Mathematik beschrieben, verfügbare Technologie beschrieben und deren Einsatz in einem Umsetzungskonzept dargestellt. Das Umsetzungskonzept wird pilothaft implementiert. Dies erfolgt in der Umgebung des Internet in der Sprache Java unter Verwendung eines Versionsverwaltungswerkzeuges und relationalen Datenbanken.
There exists a big gap between the capabilities of current 3D-CAD applications and their actual usage in practice. Many architects and planners still prefer to draft in 2D because the benefits of 3D modeling are difficult to explain. This presentation offers a basis to view the 3D building model not merely as the source for 2D plan generation. By adding extra dimensions like Time and Cost to the 3D building model it becomes possible to generate dynamic information on building construction progress with regards to used material, resources and cost. These additional benefits are key elements to many planners and contractors and may therefore widen the acceptance of 3D building modeling in general.
In this Paper, we explored the relation between the electricity consumption in residential sector and the automobile energy consumption in transportation sector in accordance with the location of city by employing Geographic Information System (GIS). We found in the study that the electricity consumption per capita has a tendency that is higher in city center and lower in suburbs in Utsunomiya city. It is also noted that there is little difference among total consumption between city center and suburbs, despite the fact that the density of electric appliances tends to increase in a small size house of city center and the amount of automobile energy consumption from residence is lower in city center than in suburbs.
Digital maps are very easily applied as route guide maps. Route guide maps are provided through Web or a mobile phone services, and demand for such services is increasing. However, the production of a route guide map requires a great deal of time. Therefore, it is difficult for general users to make route guide maps. The purpose of the present research is the development of a system that can generate a route guide map using the Digital Map 2500 (Spatial Data Framework) published by the Geographical Survey Institute. This system will not require advanced equipment or expert knowledge. Therefore, anyone can produce route guide maps easily and quickly. By using the Digital Map 2500, the time and cost required in order to generate a map are reduced. Moreover, a useful route guide map can be created by simplifying the map form based on the human cognitive map.
A large-scale computer modeling and simulation method is presented for environmental flows in urban area. Several GIS and CAD data were used for the preparation of shape model and an automatic mesh generation method based on Delaunay method was developed. Parallel finite element method based on domain decomposition method was employed for the numerical simulation of natural phenomena. The present method was applied to the simulation of flood flow and wind flow in urban area. The present method is shown to be a useful planning and design tool for the natural disasters and the change of environments.

Pre-stressed structural elements are widely used in large-span structures. As a rule, they have higher stiffness characteristics. Pre-stressed rods can be applied as girders of different purpose, and as their separate parts, e.g. rods of trusses and frames. Among numerous ways of prestressing the compression of girders, trusses, and frames by tightenings from high-strength materials is under common application.
Research on Establishment of a Standard of Traffic Impact Assessment with Integrated Database System
(2004)
Planning support systems, such as geographical information system (GIS) and traffic flow simulation models, are widely in use in recent urban planning research. In this paper we propose a method to apply traffic impact assessment (TIA) to large-scale, commercial developments. In TIA research we often encounter the problem of increasing amount of data that is necessary for detailed investigation and analysis, as the scale of commercial developments become larger and more complex. As a result, TIA presents two problems. The first problem is the difficulty of data acquisition. The second problem is the reliability of data. As a solution, we developed an integrated database system.
