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.

1975 was declared the International Year of Women by the United Nations. The first UN Conference on Women and Development was held in Mexico City in 1975 under the motto 'Equality, Development and Peace'. At this conference, the objectives for the first UN Decade of Women (1976-1985) were set: equality between the sexes was to be achieved within the framework of changed relations between North ...

The use of bundled bars in highly loaded concrete members instead individual can reduce or even avoid reinforcement congestion, allowing easier placing and compaction concrete, since bundles (with two more side-by-side bars) are less obstructive to fresh-concrete flow. However, there is still a lack knowledge the fundamental phenomena related bond behavior bundles. Therefore, design code rules ...
