This deliverable provides a look at the social, legal and regulatory aspects of network and information security in the Future Internet. It will indicate how likely are the future threats identified in the project to cause serious impacts on the society and the economy, whether or not European legislation is in place to deal with them, if the countermeasures developed for them are applicable in...

Construction contractors have big influences upon projects and their successes. Therefore, it is quite critical to select a qualified contractor in the process of construction management. A competent construction contractor is one of the indispensable conditions of a proper process and completion of a construction project. There are several theoretical frameworks or models applied in the evalua...

OBJECTIVE The aim of this study was to test for differences in injury rates for contractor-operated underground coal mines relative to owner-operated mines in Kentucky, controlling for other covariates. METHODS We used disparities between MSHA contractor data and surface reclamation permit data to identify mines operated by contractors. We then used negative binomial regression to estimate in...

A side-effect of the national debate about employer-provided benefits has been to focus attention on the cost of hiring and retaining employees. This has led to renewed interest in the issue of when a worker is an employee vs. an independent contractor. The IRS must make determinations regarding worker status. This determination process which has evolved through judicial precedent, is subjectiv...

We propose an eigenvalue contractor for symmetric matrices. Given a symmetric interval matrix A and an interval approximation of its eigenvalue sets λ1, . . . ,λn the contractor reduces the entries of A S such that no matrix with eigenvalues in λ1, . . . ,λn is omitted. Our contractor is based on sequentially reducing the entries of A. We discuss properties of the method and demonstrate its per...

One of the fundamental activities in multiagent systems is the exchange of tasks among agents (Davis & Smith 1983). In particular, we are interested in contracts among selfinterested agents (Sandholm & Lesser 1995), where a contractor desires to find a contractee that will perform the task for the lowest payment, and a contractee wants to perform tasks that maximize its profit (payment received...

This paper describes preconditioned conjugate gradient methods for solving sparse symmetric and positive definite systems of linear equations. Necessary and sufficient conditions are given for when these preconditioners can be used and an analysis of their effectiveness is given. Efficient computer implementations of these methods are discussed and results on the CYBER 203 and the Finite Elemen...

In many countries, state and private owners often categorize contractors into various groups based on their capacities as well as their previous performance. These categories are then used for several purposes including contract award and prequalification. A number of different statistical algorithms can be used to categorize the contractors. No one algorithm can be used globally in all situati...

F iscal regime is one of the main differences between petroleum contracts. Fiscal regimes in oil contracts are divided to two main categories namely Concessionary and Contractual Systems. In contractual systems, the main difference between service and production sharing contracts is the way of compensation of contractor services which could be in cash or in kind. In production sharin...
