by humans and computers. They also allow machines to produce or update semantic wiki pages as humans can do. This opens the opportunity to consider machines as new member of communities to produce and maintain knowledge. ``Smart agents'' can reduce the overhead of communities in the process of continuously knowledge building and correct humans errors. A smart agent can compute automatically cat...

This paper aims at examining the sustainability of smartcard payment in retailing and consumer services. The analytical results of our survey data suggest that usefulness, ease of use, convenience, automatic addvalue service, security, reliability, and participation of popular service providers have considerable effects on continuous use of smartcard payment. The present work empirically identi...

The smart meter (SM) privacy problem is addressed together with the cost of energy for the consumer. It is assumed that a storage device, e.g., an electrical battery, is available to the consumer, which can be utilized both to achieve privacy and to reduce the energy cost by modifying the energy consumption profile. Privacy is measured via the squared-error distortion between the SM readings, w...

Cities are facing many challenges; challenges linked to world-wide trends like urbanisation, climate changes and globalisation. In parallel to these trends, we have seen a rapid digitalisation in and of different parts of society. Cities and local governments have been appointed an important role in overcoming these world-wide challenges, and subsequently, in policy practices digitalisation is ...

2011 This paper was commissioned by the Education for All Global Monitoring Report as background information to assist in drafting the 2012 report. It was presented at a Meeting of experts on " Expanding opportunities for the marginalized through skills development " organized by the GMR and BMZ in Bonn, Germany (3-4 November 2010). The paper has not been edited by the team. The views and opini...

Implementing smart metering is an important field for energy policy to successfully meet energy efficiency targets. From an integrated social acceptance and customer perceved vaue theory perspective we model the importance of customer value of smart metering in this regard. ...

Finding an optimal coalition structure is a hard problem. In order to simplify this process, it is possible to explore some characteristics of the agents organization. In this paper we propose an algorithm that deals with a particular family of games in characteristic function, but is able to search in a much smaller space by considering organizational issues such as constraints in the number o...

A threat analysis framework and methodology was developed by the authors to catalogue threats, vulnerabilities, attacks and countermeasures for smart cards (contact and contactless) and wireless sensor network node technologies. The goal of this research was to determine “Security Lessons” learned from the world of smart cards that may be applied to wireless sensor network nodes and vice versa.

It is important to develop tools that support sense-making by providing representations that help to capture the externalisation of the thinking process. The paper focuses on a new method for identifying the sense-making processes of experts by combing probes with cognitive task analysis methods. The data-frame sense-making model is used as a theoretical frame, and the probes have been develope...

Global energy generation and delivery systems are transitioning to a new computerized “smart grid”. One of the principle components of the smart grid is an advanced metering infrastructure (AMI). AMI replaces the analog meters with computerized systems that report usage over digital communication interfaces, e.g., phone lines. However, with this infrastructure comes new risk. In this paper, we ...
