Service-oriented support of cooperative workflows considerations for urban planning processes
Web-based information sources have evolved to an essential element in our daily and professional life. To process this faster and faster growing amount of information, web portals provide personalized access to specific information and communication services. In this paper, an example from urban planning is given. In this workflow, different actors are interacting in an ad-hoc manner. Therefore, a Portal Architecture has been built up, which provides the relevant information. This paper proposes a Service Orientated Architecture to provide access to business processes, software applications and hardware resources in a workflow oriented way.

Developing Web applications for mobile devices
Today, even small mobile devices access the Internet. Therewith, mobility issues have become an important technical and economic topic - not only in new but in proven and successful Web applications as well. The main problem derives from a growing development of heterogeneity in hardware and software of mobile devices. To overcome this problem, this paper presents a framework to develop Web applications for mobile devices. This framework issues important points when developing web application that also focuses on mobile users. This includes completely new developments, as well as development that issue an upgrade of existing Web applications to mobile devices. An important element in this framework is the employment of the fairly new CC/PP standard.

Estimation of class membership functions for grey-level based image fusion
In this paper we propose a new unsupervised method for estimating class membership functions from statistical data. It combines in an original way information derived from the histogram as well as prior knowledge of the requirements that the functions must satisfy and that cannot be derived from the histogram. The method has been tested successfully on MR brain images, and applications to image fusion are illustrated.

An Aggregating Discovery Service for the EPCglobal Network
Although the achievements of EPCglobal standardization efforts in the last years are substantial and the diffusion of the EPCglobal network continues, a service to access item-level information stored at potentially unknown supply chain partners is still missing. Without this 'Discovery Service' the EPCglobal network cannot be used with unknown business partners. In this contribution we present a novel Discovery Service approach. In contrast to other Discovery Service approaches we use the Discovery Service to aggregate the data of interest. This eliminates problems other approaches cannot solve, e.g. assuring data ownership, low access control maintenance effort, and minimal complexity for the information requester. We present a requirements model, describe the implementation of our Discovery Service approach, and compare it to existing Discovery Service approaches. Finally we show how to overcome scalability challenges to implement our Discovery Service approach in a real-world environment.

Collaborative Smart Items
Business information systems provide computer support for decision making across huge data sets. Smart Items are miniaturized computer and sensing systems embedded into physical goods, items and assets. This paper proposes collaborative Smart Items for pushing business relevant computing as close as possible into the real world. Collaboration is enabled through an auction-based negotiation mechanism running distributed between the Smart Items. This mechanism serves as an abstraction across Smart Items in order to enable a common reasoning on business critical contexts as they may occur in logistics, safety and highly dynamic planning scenarios. In this paper, we investigate auction-based collaboration for Smart Items and present first experimental results. We conclude that auctions facilitate reliable business information processing even under harsh industrial conditions such as information loss or device failure.

Improving supply chain visibility through RFID data
In our work, which is still in progress, we examine the visibility potentials of RFID technology within the context of Supply Chain Management (SCM). This analysis is conducted systematically by matching identified SCM visibility requirements and general RFID visibility potentials. Building on a four-step approach, we show how visibility in supply chains can be improved on the basis of RFID-generated data, and what impact this increase in visibility has on the goals of SCM.

Gain in Transparency versus Investment in the EPC Network - Analysis and Results of a Discrete Event Simulation Based on a Case Study in the Fashion Industry
The diffusion rate of Radio Frequency Identification (RFID) technology in supply chains is lower than expected. The main reason is the doubtful Return On Investment (ROI) mainly due to high tag prices. In this contribution, we leverage a prototypical RFID implementation in the fashion industry, extend this prototype by a discrete event simulation, and discuss the impact of an Electronic Product Code (EPC)-enabled supply chain concerning higher visibility. Thereby, we illustrate the benefit of the EPC network for Supply Chain Event Management (SCEM). Future researchers are provided with the simulation data which is available online and can be investigated.
