An increasingly large number of firms outsource their Information Technology (IT). Firms that contemplate IT outsourcing have two alternatives: (1) contract with a vendor (i.e., outsourcing) or (2) set up their own IT subsidiary (i.e. quasi-outsourcing). This study examines some of the determinants of the outsourcing vs. quasi-outsourcing decision. Using primary data collected in France and Ger...

— A code is said to be two-weight if the non-zero codewords have only two different a weight w 1 and w 2. Two-weight codes are closely related to strongly regular graphs. In this paper. It is shown that a consta-cyclic code of composite length can be put in the quasi-twisted form. Based on this transformation, a new construction method of quasi-twisted (QT) two-weight codes is presented. A larg...

The aim of this paper is to consider time-dependent variational and quasi-variational inequalities and to study under which assumptions the continuity of solutions with respect to the time can be ensured. Making on appropriate use of the set convergence in Mosco’s sense, we get the desiderate continuity results for strongly monotone variational and quasi-variational inequalities. The continuity...

We show how Max-SMT-based invariant generation can be exploited for proving non-termination of programs. The construction of the proof of nontermination is guided by the generation of quasi-invariants – properties such that if they hold at a location during execution once, then they will continue to hold at that location from then onwards. The check that quasi-invariants can indeed be reached i...

We examine the Fermi-surface effect called nesting for Fulde–Ferrell–Larkin–Ovchinnikov (FFLO) state in strongly Pauli-limited quasi-two-dimensional superconductors, focusing on of three-dimensional factors, such as interlayer electron transfer, pairing, and off-plane magnetic fields including those perpendicular to most conductive layers (hereinafter fields). systems with a large Maki paramete...

It is well known that intra-regular semigroups (ordered semigroups) play an essential role in studying the structure of semigroups (ordered semigroups). In this paper we present a structure theorem referring to the decomposition of ordered semigroups into left strongly simple components, that is, into components, which are both simple and left quasi-regular. We prove, among others, that if an o...

in this paper we investigate decompositions of submodules in modules over a proufer domain into intersections of quasi-primary and classical quasi-primary submodules. in particular, existence and uniqueness of quasi-primary decompositions in modules over a proufer domain of finite character are proved. proufer domain; primary submodule; quasi-primary submodule; classical quasi-primary; decomposi...
