By means of Contractor Iteration Method, we solve and visualize the Lane-Emden(-Fowler) equation Δu+ u = 0, in Ω, u = 0, on ∂Ω. It is shown that the present method converges quadratically as Newton’s method and the computation of Contractor Iteration Method is cheaper than the Newton’s method. Keywords—Positive Solutions; Newton’s Method; Contractor Iteration Method; Eigenpairs.

This article studies the role of installment payments in relationships characterized by moral hazard and sunk costs. We rule out vertical integration and payments contingent on the product of the contractor. Instead, each payment is negotiated as and when made. In such circumstances, an initial (down)payment serves to redress the weakness of the contractor in ex post renegotiations. Ifhigher ef...

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...

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...
