in most cases, fiber reinforced self-compacting concrete (frscc) contains only one type of fiber. the use of two or more types of fibers in a suitable combination may potentially not only improve the overal properties of self-compacting concrete, but may also result in performance synergie. the combining of fibers, often called hybridization, is investigated in this paper for a cimentetious mat...

Lisp applications need to show a reasonable cost-beneet relationship between the ooered expressiveness and their demand for storage and run-time. Drawbacks in eeciency, apparent in Lisp as a dynamically typed programming language, can be avoided by optimizations. Statically inferred type information can be decisive for the success of these optimizations. This paper describes a practical approac...

In this paper, we present constructions of abelian Paley type group schemes by using multiplicative characters of finite fields and Arasu-Dillon-Player difference sets. The constructions produce many new Paley type group schemes that were previous unknown in our classification of Paley type group schemes in finite fields of small orders.

This study investigates the process of perpetration and concealment of management fraud in financial statements. First, we argue that fraud schemes consist of two components: “account schemes” and “evidence schemes.” Account schemes are the schemes through which management perpetrates fraud by manipulating account balances or disclosures. Evidence schemes are the schemes through which managemen...

A new construction is described for designing secret-key certiicate schemes based on signature schemes other than of the Fiat-Shamir type. Also described are practical secret-key certiicate issuing protocols that enable the Certiication Authority to certify public keys, without being able to compromise the conndentiality of the corresponding secret keys. Furthermore the design of secure showing...
