To appear: Proc. 2nd International Conference on Pervasive Computing (Pervasive 2004) c © Springer-Verlag Berlin Heidelberg 2004 Abstract. When smart objects participate in context-aware applications, changes in their real-world environment can have a significant impact on underlying networking structures. This paper presents a communication platform for smart objects that takes an object’s cur...

The availability of new self-sensing cement-based strain sensors allows the development of dense sensor networks for Structural Health Monitoring (SHM) of reinforced concrete structures. These sensors are fabricated by doping cement-matrix materials with conductive fillers, such as Multi Walled Carbon Nanotubes (MWCNTs), and can be embedded into structural elements made of reinforced concrete p...

Purpose-French universities can play a key role in generating Smart City approach through an innovative Public-Private Partnership dedicated to urban transformation. Methodology-We led an action-research study for five years with several research and pedagogic projects including users or citizens. Findings-The paper points out main factors of Smart City development. It also presents shared demo...

Many companies have designed and manufactured smart cards, which vary greatly in both the hardware they use and software development environments they provide. Java Card promises to make smart card programming easier, by introducing a common programming language and run–time environment. Also as a member of the Java family, Java Card raises up hopes of easy software portability from PCs to smar...

background: in megavoltage radiotherapy rooms, ordinary concrete is usually used due to its low construction costs, although higher density concrete are sometimes used, as well. the use of high-density concrete decreases the required thickness of the concrete barrier hence, its disadvantage is its high cost. in a nuclear reactor, neutron radiation is the most difficult to shield. a method for p...

Surfaces of carbon fibre roving were modified by means of a low temperature plasma treatment to improve their bonding with mineral fines; the latter serving as an inorganic fibre coating for the improved mechanical performance of carbon reinforcement in concrete matrices. Variation of the plasma conditions, such as gas composition and treatment time, was accomplished to establish polar groups o...

The paper gives an overview on the meta-data specification for administrating and enforcing enterprisewide security for heterogeneous and distributed information systems. The meta-data serves as a basis to maintain enterprise-wide security information centrally, to integrate isolated security specifications, to keep the consistency between different security policies, and to perform access cont...

This paper addresses the security of public-key cryptosystems in a \multi-user" setting, namely in the presence of attacks involving the encryption of related messages under di erent public keys, as exempli ed by H astad's classical attacks on RSA. We prove that security in the single-user setting implies security in the multi-user setting as long as the former is interpreted in the strong sens...

We identify a flaw in the security proof and a flaw in the concrete security analysis of the WOTS-PRF variant of the Winternitz one-time signature scheme, and discuss the implications to its concrete security.
