Electronic Marketplaces (or e-Marketplaces) require technologies which provide support for the adaptability, flexibility and
the integration of business applications in order to meet rapid changes in business environment. Traditional web technologies
are unable to meet the new business requirements which are derived from the rapid growth of e-Marketplaces. In this research,
a service-oriented framework is proposed in order to address the issues associated with the development of e-Marketplaces.
Specifically, it introduces a generic trading model oriented to e-Marketplaces so as to overcome the inadequacy of existing
models and to facilitate the development of a computational trading process. In the proposed framework, required services
are identified through the utilization of the business-centric trading model. Using a service metamodel, services are equipped
with intelligence such that they work seamlessly and coherently within and across e-Marketplaces. A multi-model driven integrated
development platform has been developed to support the proposed models and framework. The proposed framework and concepts
have been validated through a case study of a mutual funds auction in an e-Marketplace.

There are only a few ethical regulations that deal explicitly with robots, in contrast to a vast number of regulations, which
may be applied. We will focus on ethical issues with regard to “responsibility and autonomous robots”, “machines as a replacement
for humans”, and “tele-presence”. Furthermore we will examine examples from special fields of application (medicine and healthcare,
armed forces, and entertainment). We do not claim to present a complete list of ethical issue nor of regulations in the field
of robotics, but we will demonstrate that there are legal challenges with regard to these issues.

A number of mobile applications have emerged that allow users to locate one another. However, people have expressed concerns
about the privacy implications associated with this class of software, suggesting that broad adoption may only happen to the
extent that these concerns are adequately addressed. In this article, we report on our work on P eopleF inder, an application that enables cell phone and laptop users to selectively share their locations with others (e.g. friends,
family, and colleagues). The objective of our work has been to better understand people’s attitudes and behaviors towards
privacy as they interact with such an application, and to explore technologies that empower users to more effectively and
efficiently specify their privacy preferences (or “policies”). These technologies include user interfaces for specifying rules
and auditing disclosures, as well as machine learning techniques to refine user policies based on their feedback. We present
evaluations of these technologies in the context of one laboratory study and three field studies.

This paper studies the steady-state queue length process of the MAP/G/1 queue under the dyadic control of the D-policy and multiple server vacations. We derive the probability generating function of the queue length and the mean queue
length. We then present computational experiences and compare the MAP queue with the Poisson queue.

In this paper, we present a method for development and specification of web services based on the quality system documentation.
The general assumption is that service oriented architecture is based on business services and these business services mostly
correspond to exchanged documentation in a real business system. Documentation of a quality system is recognized in form of
documents that describe business processes in a real business system and identify exchanged documentation with environment.
Presented method uses documentation of quality system and documentation flow for web service specification. We developed the
CASE tool for web service specification based on a new approach, and we compare it to other existing tools.

Image registration is a computationally intensive application in the medical imaging domain that places stringent requirements
on performance and memory management efficiency. This paper develops techniques for mapping rigid image registration applications
onto configurable hardware under real-time performance constraints. Building on the framework of homogeneous parameterized
dataflow, which provides an effective formal model of design and analysis of hardware and software for signal processing applications,
we develop novel methods for representing and exploring the hardware design space when mapping image registration algorithms
onto configurable hardware. Our techniques result in an efficient framework for trading off performance and configurable hardware
resource usage based on the constraints of a given application. Based on trends that we have observed when applying these
techniques, we also present a novel architecture that enables dynamically-reconfigurable image registration. This proposed
architecture has the ability to tune its parallel processing structure adaptively based on relevant characteristics of the
input images.

Currently, standards for web services are being developed via three different initiatives (W3C, Semantic web services and
ebXML). To the best of our knowledge, no theoretical perspectives underlie these standardization efforts. Without the benefit
of a strong theoretical basis, the results, within and across these initiatives, have remained piecemeal. We suggest ‘Language–Action
Theories’ as a plausible perspective that can effectively define, assess and refine web services standards. In this paper,
we first investigate the existing initiatives to identify commonalities that point to theories of ‘Language–Action’ as an
appropriate theoretical basis for web services standards. Next, we adapt work from these theories to develop a comprehensive
reference framework for understanding web services standards. Finally, we use this reference framework to assess the three
initiatives, and analyze the findings to provide insights for future development and refinement of web services standards.

This paper describes the simulated car racing competition that was arranged as part of the 2007 IEEE Congress on Evolutionary
Computation. Both the game that was used as the domain for the competition, the controllers submitted as entries to the competition
and its results are presented. With this paper, we hope to provide some insight into the efficacy of various computational
intelligence methods on a well-defined game task, as well as an example of one way of running a competition. In the process,
we provide a set of reference results for those who wish to use the simplerace game to benchmark their own algorithms. The paper is co-authored by the organizers and participants of the competition.

In this paper we present an application fostering the integration and interoperability of computational lexicons, focusing
on the particular case of mutual linking and cross-lingual enrichment of two wordnets, the ItalWordNet and Sinica BOW lexicons.
This is intended as a case-study investigating the needs and requirements of semi-automatic integration and interoperability
of lexical resources, in the view of developing a prototype web application to support the GlobalWordNet Grid initiative.
