Electronic commerce becomes an important competitive advantage for small and medium-sized enterprises. Those enterprises therefore need a tool to easily exhibit and sell their products on the Internet. Electronic shops are the best solution to be accessible online but can be quite expensive. This paper presents eSarine, a Struts-based open source webshop, which is especially designed for small ...

In this paper the concept and design of a software framework which provides a transparent data flow for interactive Mixed Reality (MR) applications is discussed. The design was affected by our demands on platform independency, simplicity, network transparency, maximum performance and availability of runtime debugging facilities. Our software framework tries to simplify the development of MR app...

The beamline network system at SPring-8 consists of three LANs; a BL-LAN for beamline component control, a BL-USER-LAN for beamline experimental users and an OA-LAN for the information services. These LANs are interconnected by a firewall system. Since the network traffic and the number of beamlines have increased, we upgraded the backbone of BL-USER-LAN from Fast Ethernet to Gigabit Ethernet. ...

In this paper we present a new approach to reasoning about actions and causation which is based on a conditional logic. The conditional implication is interpreted as causal implication. This makes it possible to formalize in a uniform way causal dependencies between actions and their immediate and indirect effects. The proposed approach also provides a natural formalization of concurrent action...

The criterion used for partitioning is d-separation: a parallel between causal independency property and vertex separation in digraphs. If X, Y and Z represent the vertex subsets of two neighbouring partition regions and respectively the border between them, the d-separation criterion is used to decide if " knowing Z renders Y irrelevant to X ". It follows that diagnosis may be performed locall...

Emotional surveillance of drivers possesses significant potential for increased security within passenger transport. In an automotive setting the interaction can further be improved by social awareness of an MMI. Within this scope the detection of security relevant behavior patterns as aggressiveness or sadness is discussed. The focus lies on real-life usage respecting online processing, subjec...

Pawlak recently introduced rough set flow graphs (RSFGs) as a graphical framework for reasoning from data. No study, however, has yet investigated the complexity of the accompanying inference algorithm, nor the complexity of inference in RSFGs. In this paper, we show that the traditional RSFG inference algorithm has exponential time complexity. We then propose a new RSFG inference algorithm tha...

Figure 1 illustrates the general FTTx (Fiber-to-the-x) architecture using a WDM-PON (Wavelength Division Multiplexed Passive Optical Network). As can be seen in the figure, this general-purpose architecture can serve multiple applications for both the business and residential customer. This functionality is possible since each end point is connected to the central office through a dedicated bid...

We present the design of an asynchronous microcontroller core featuring binary compatibility with the MCS 251 family. The work is involved in a specific application project targeting portable electromagnetic measurement systems with very low power consumption. Delay insensitivity was chosen to allow a fast design of complex but safe asynchronous circuits, by means of automatic synthesis and ind...

Vehicular manufacturers want to reduce the number of electronic components in the vehicles foremost to reduce cost and complexity, but not to the price of decreased functionality or quality. In this work we outline a method to facilitate a reduction of hardware components in vehicles, through integration of large real-time software components to the same hardware platform. The focus is on contr...
