A Social Semantic Infrastructure for Decentralised Systems Based on Specification-Carrying Code and Trust
Decentralised systems made of autonomous devices and software are gaining more and more interest. These autonomous el ements usually do not know each other in advance and act without any central control. They thus form a society of devices and software, and as such need: basic interaction mechanisms for understanding each other and a social infrastructure supporting interactions...

Specification-Carrying Code for Self-Managed Systems
This paper proposes the notion of Specification-Carrying Code as an interaction mechanism for self-assembly of au- tonomous decentralised software components. Each au- tonomoussoftware entity incorporates more informationthan its operational behaviour, and publishes more data than its signature. The idea is to provide separately, for each en- tity, a functional part implementing its...

Towards an application framework for context-aware m-health applications
Several social-economical developments, like the ageing society, stimulate the use of ICT applications for mobile healthcare (e.g., tele-monitoring). To support novel m-health applications, the consequences of developing these applications should be considered in the scope of a comprehensive architecture. Additionally, contextual information plays an important role for personalised...

Context-aware QoS provisioning in an m-health service platform
Inevitably, healthcare goes mobile. Recently developed mobile healthcare (i.e. m-health) services allow healthcare professionals to monitor mobile patient's vital signs and provide feedback to this patient anywhere at any time. Due to the nature of current supporting mobile service platforms, m-health services are delivered with a best-effort, i.e., there are no guarantees on...

Measurements-based performance evaluation of 3G wireless networks supporting m-health services
The emergence of 3G networks gives rise to new mobile services in many different areas of our daily life. Examples of demanding mobile services are mobile-healthcare (i.e. m-health) services allowing the continuous monitoring of a patient's vital signs. However, a prerequisite for the successful deployment of m-health services are appropriate performance characteristics of...

Strategic behavior and underpricing in uniform price auctions: Evidence from finnish treasury auctions
We contribute to the debate on the optimal design of multiunit auctions by developingand testing robust implications of the leading theory of uniform price auctions on the bid distributions submitted by individual bidders. The theory, which emphasizes market power, has little support in a data set of Finnish Treasury auctions. A reason may be that the Treasury acts strategically by...

Comment on William C. Brainard and Herbert E. Scarf's "How to Compute Equilibrium Prices in 1891"
Bill and Herb have provided an illuminating and interesting presentation of Irving Fisher's Ph.D. dissertation Mathematical Investigations in the Theory of Value and Prices. They correctly emphasize that Fisher's fundamental contribution to the early theory of general equilibrium was the construction of a machine to compute the equilibrium quantities in a Walrasian model of...

Divisible good auctions: the role of allocation rules
We examine the role of allocation rules in determining the set of equilibrium prices in uniform- price auctions. Beginning with Wilson (1979), the theoretical literature has argued that these auctions are subject to possible low equilibrium prices. We show that this is due to the way the asset is being divided. We focus on allocation rules that specify the way the asset is divided in...

Mobile Health Care over 3G Networks: the MobiHealth Pilot System and Service
Health care is one of the most prominent areas for the application of wireless technologies. New services and applications are today under research and development targeting different areas of health care, from high risk and chronic patients' remote monitoring to mobility tools for the medical personnel. In this direction the MobiHealth1 project developed and trailed a system...

MobiHealth: ambulant patient monitoring over next generation public wireless networks
The use of health BANs together with advanced wireless communications enables remote management of chronic conditions and detection of health emergencies whilst maximising patient mobility. MobiHealth1,2 has developed a generic Body Area Network (BAN) for healthcare and an mhealth service platform. Biosignals measured by sensors connected to the BAN are transmitted to the remote...

Towards digital libraries of virtual hyperbooks
This paper describes a technique for integrating several (many) virtual hyperbooks in a digital library. We consider a virtual hyperbook model that comprises a domain ontology. By interconnecting the hyperbook's ontologies, we can create a multi-point of view ontology that describes a set of hyperbooks. A hypertext interface specification language can use this ontology to...

Integration of Hyperbooks into the Semantic Web
A crucial aspect of the Semantic Web is the capacity to add formalized meanings to information to enable non-human actors to process it. This is usually accomplished by linking the information to an ontology that describes the domain's concepts. In the Web's context it does not seem realistic to represent this semantic layer on a central server, as this model would not...

Trust as an Interaction Mechanism for Self-Organising Engineered Systems
Emerging computing infrastructures are heterogeneous, ubiquitous and mobile. Devices from personal computers, to handhelds, to printers, to embedded devices are very widely available. Further, today's wireless network infrastructures make it possible for devices to spontaneously interact. Many devices are mobile, carried by people or mobile machines. Thus, the environment...

"Using Exception Handling for Fault-Tolerance in Mobile Coordination-Based Environments", Exception Handling in Object Oriented Systems: towards Emerging Application Areas and New Programming Paradigms
Exception handling continues to be a challenging problem in object oriented system development. One reason for this is that today's software systems are getting increasingly more complex. Moreover, exception handling is needed in a wide range of emerging application areas, sometimes requiring domain-specific models for handling exceptions. Moreover, new programming paradigms...

Semantic Service Oriented Architecture
This paper describes a new prototype of a semantic Service Oriented Architecture (SOA) called Spec Services. Instead of publishing their API through a protocol like SOAP, as Web Services do, services can register to a service manager a powerful syntactic description or even semantic description of their capabilities. The client entity will then send a syntactic or semantic...
