In this paper we propose a core, lightweight ontology around the axis of a serious game for adolescents. The Player-Specific Conflict Handling Ontology (PSCHO) that we propose provides a formal representation of the conflict in the domain of serious games. In particular, it maps visually manifested affective cues and emotional stimuli from the serious game to conflict handling styles, and sugge...

The evolution of embedded systems and their applications in every daily activity, derive the development of lightweight cryptography. Widely used crypto-libraries are too large to fit on constrained devices, like sensor nodes. Also, such libraries provide redundant functionality as each lightweight and ultra-lightweight application utilizes a limited and specific set of crypto-primitives and pr...

In this work, we present a practical passive attack on SASI, an ultra-lightweight mutual authentication protocol for RFID. This attack can be used to reveal with overwhelming probability the secret ID of the prover by eavesdropping about 2 authentications. The result dismantles SASI and, more generally, provides a new approach that threatens ultra-lightweight authentication protocols.

This paper was conducted to study the behavior of lightweight concrete, incorporating local lightweight aggregate (LWA), in terms of chloride ion permeability at different ages. The effect of lightweight fine aggregate replacement by normal weight sand (0, 25, 50 and 75% by volume) was investigated. Constant level of silica fume content (10% by weight of cement) as an addition was also consider...

A detailed analysis of the power demand an ultraefficient lightweight-battery electric vehicle is performed. The aim to overcome problem lightweight vehicles that may have a relatively bad environmental impact if their not extremely reduced. In particular, higher during production phase, which should be balanced by lower service life means design. As example vehicle, prototype for Shell Eco-mar...

We investigate a Web information structuring mechanism called lightweight deductive databases. Lightweight deductive databases enable more sophisticated automated searching, extraction, and processing, and can facilitate agent-based programming. We also explore how these deductive databases bene t from being distributed on the Web.
