Software engineers today are often asked to do both rapid production and careful engineering at the same time. One way to help resolve the tension between these often conflicting goals is to develop families of software and to invest in facilities for rapidly producing family members. Success in such an endeavor requires that the software engineers be able to identify the desired family members...

The second variation operator of minimal submanifolds of Riemannian manifolds (the Jacobi operator) carries information about stability properties of the submanifold when it is thought of as a critical point for the area functional. When the ambient Riemannian manifold is a sphere S, Simons [S] characterized the totally geodesic submanifolds as the minimal submanifolds of S either with the lowe...

We study the complexity of Banach space valued integration in the randomized setting. We are concerned with r-times continuously differentiable functions on the d-dimensional unit cube Q, with values in a Banach space X, and investigate the relation of the optimal convergence rate to the geometry of X. It turns out that the n-th minimal errors are bounded by cn−r/d−1+1/p if and only if X is of ...

We propose and investigate a large class of models possessing resonance factorized S-matrices. The associated Casimir energy describes a rich pattern of renormalization group trajectories related to flows in the coset models based on the simply laced Lie Algebras. From a simplest resonance S-matrix, satisfying the “φ3-property”, we predict new flows in non-unitary minimal models. Pacs numbers: ...

Let G be a simple graph of order n and minimal degree > cn (0 < c < 1=2). We prove that (1) There exist n0 1⁄4 n0(c) and k 1⁄4 k(c) such that if n > n0 and G contains a cycle Ct for some t > 2k ; then G contains a cycle Ct 2s for some positive s < k ; (2) Let G be 2-connected and nonbipartite. For each " (0 < " < 1), there exists n0 1⁄4 n0(c; ") such that if n n0 then G contains a cycle Ct for ...

This paper presents a template for the commonality analysis of a family of models of physical phenomena. The commonality analysis template includes documentation of the potential system context, the variabilities between models and the common aspects shared by all family members, including sections for terminology, goals, assumptions and theoretical models. The commonality analysis document als...

OBJECTIVE In this study, we evaluated the frequency of FMS-like tyrosine kinase 3 (FLT3-ITD and FLT3-TKD) and nucleophosmin (NPM1) mutations in Iranian patients with cytogenetically normal acute myeloid leukemia (CN-AML). The clinical and laboratory characteristics were compared between wild-type and mutant cases. MATERIALS AND METHODS Seventy newly diagnosed de novo AML patients were recruit...

Firms often determine whether or not to make components common across products by focusing on the manufacturing and sales of new products only. However, component commonality decisions that ignore remanufacturing can adversely affect the profitability of the firm. In this paper, we analyze how remanufacturing could reverse the OEM’s commonality decision that is based on the manufacturing and sa...

Component commonality and postponement have been the focus of research for the last twenty years. Since then numerous models and theories have been developed, but industrial evidence is still rare. This work will make a contribution and show the positive benefits of postponement and component commonality in the automotive industry. The insights from literature and a case study are combined to e...
