This paper presents a middleware platform, Prottoy for the development of smart object systems. A smart object has some specific characteristics e.g., augmentation variation, perceptual feedback provision, push-pull model, etc. In addition a smart object could be stand-alone, co-operative or associated with an external application. Generic pervasive middlewares have no clean support for accommo...

The smart meters in electricity grids enable fine-grained consumption monitoring. Thus, suppliers could adjust their tariffs. However, as smart meters are deployed within the smart grid field, authentication and key establishment between smart grid parties (smart meters, aggregators, and servers) become an urgency. Besides, as privacy is becoming a big concern for smart meters, smart grid parti...

Smart environments integrate a multitude of different device ensembles and aim to facilitate proactive assistance in multi-display scenarios. However, the integration of existing software, especially visualization systems, to take advantage of these novel capabilities is still a challenging task. In this paper we present a smart view management concept for an integration that combines and displ...

The smart card has a microprocessor or a memory chip embedded in a plastic card. It has been in wide use in Europe and Japan for payment, entry into buildings and computer systems, and storage and access of special types of information. In the US, despite efforts by the credit card industry, the smart card has not been nearly as widely adopted as in Europe and Japan. In this article, we will re...

This paper explores the effects of in-class level differentiation by making innovative use of an interactive whiteboard (SMARTboard) on math proficiency. Therefore, we evaluate the use of SMARTboard in class, in combination with teacher training, using a randomized field experiment among 199 pre-vocational students in 7 th -grade in the Netherlands. During six weeks, students in the interventio...

In this thesis we propose a design for a ubiquitous and interoperable device based on the smart card architecture to meet the challenges of privacy, trust, and security for traditional and emerging technologies like personal computers, smart phones and tablets. Such a device is referred a User Centric Tamper-Resistant Device (UCTD). To support the smart card architecture for the UCTD initiative...

Smart environments integrate Information and Communication Technologies (ICT) into devices, vehicles, buildings and cities to offer an increased quality of life, energy efficiency and economical sustainability. In this perspective, the individual has a core role and so has networking, which enables such entities to cooperate. However, the huge amount of sensitive data, social aspects and the mi...
