In this paper, we define a set inequalities that are satisfied by stable multi-skill workforce schedules. In our analysis, a schedule is said to be stable if it does not contain a blocking pair, extending the notion of blocking pair in the Marriage Model of Gale-Shapley. Skill efficiency is chosen as the criterion in the preference structure. The proposed algorithm either constructs a stable mu...

LetX be a complex Banach space andX∗ its dual space. We consider the topological subspace Π X { x, x∗ : x∗ x 1 ‖x‖ ‖x∗‖} of the product space BX ×BX∗ , equipped with norm and weak-∗ topology on the unit ball BX ofX and its dual unit ball BX∗ , respectively. It is easy to see that Π X is a closed subspace of BX × BX∗ . For two complex Banach spaces X and Y , denote by Cb BX : Y the Banach space ...

A dynamic model shaping a process of knowledge management (KM) culture change is suggested. It is aimed at providing effective KM of employees for obtaining desired results in an organization. The essential requirements for obtaining KM culture change are determined. The proposed model realizes these requirements. Dynamics of the model are expressed by a change of its parameters. It is adjusted...

We investigated the release angle that maximises the distance attained in a long soccer throw-in. One male soccer player performed maximum-effort throws using release angles of between 10 and 60o, and the throws were analysed using two-dimensional videography. The player’s optimum release angle was calculated by substituting mathematical expressions for the measured relationships between releas...

In November 1998 the CSC SEAS Center achieved the rating of CMM Level 5 and became the sixth organization in the world to have ever attained that goal. The Capability Maturity Model (CMM) (Reference 1) is a worldwide recognized benchmark of process maturity for software organizations and is used to assess the quality of an organization’s software process. During the period covered by this study...

It is a cruel reality that the goal of producing “perfect software” remains elusive. When software is part of a critical system, it is necessary to estimate the risk associated with its use. Software reliability is defined as the probability of failure free execution given a specific environment and a fixed time interval. The goal of reliability assessment is not just to estimate the failure pr...

BACKGROUND The purpose of this study was to undertake an economic evaluation to compare the cost-effectiveness of recombinant (r)FSH with urinary (u)FSH for attaining clinical pregnancy with assisted reproduction. METHODS Mathematical modelling was utilized incorporating a Markovian decision framework and a Monte Carlo simulation. Statistical representations of recurrent events over time were...
