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.

This article introduces a new class of experimental designs, called split factorials, which allow for the estimation of both response surface effects (fixed effects of crossed factors) and variance components arising from nested random effects. With an economical run size, split factorials provide flexibility in dividing the degrees of freedom among the different estimations. For a split factor...

Abstract Self-consolidating concrete (SCC) is one of the trending low-yield stress material innovations new age building industry due to its ability flow through heavily reinforced structural members without segregation and losing moderate viscosity. In this research paper, a V-funnel simulation has been developed for time establish validity with allowable design conditions according European s...

Abstract. In these notes we discuss some equidistribution problems with the aim to give reasonable error rates, i.e. we are interested in effective statements. We motivate some arguments by studying a concrete problem on a two-torus, and then describe recent results on the equidistribution of semisimple orbits obtained in joint work with G. Margulis and A. Venkatesh. We end by studying the rela...

We discuss UV/IR mixing effects in non-supersymmetric noncommutative U(N) gauge theories. We show that the singular (nonplanar) terms in the 2and 3-point functions, namely the poles and the logarithms, can be obtained from a manifestly gauge invariant effective action. The action, which involves open Wilson line operators, can be derived from closed strings exchange between two stacks of Dbrane...

Indonesia is an archipelagic country with many buildings located in the coastal area. Seawater contains 3.5% salt, which can eat away at strength and durability of concrete. Sodium salts be dangerous when combined reactive alkaline aggregates, crystallization concrete cavities destroy them due to pressure. Concrete porosity important study, especially beachfront that intersect ground. In Riau P...
