Derivative-free iterative methods are useful to approximate the numerical solutions when given function lacks explicit derivative information or derivatives too expensive compute. Exploring convergence properties of such is crucial in their development. The behavior approaches and determining practical applicability require conducting local as well semi-local analysis. In this study, we explore...

A challenge is presented to the usual account of the development of the Manchester Baby which focuses on the contribution made to the project by the topologist M.H.A. (Max) Newman and other members of the Dept. of Mathematics. Based on an extensive re-examination of the primary source material, it is suggested that a very much more significant role was played by mathematicians than is allowed f...

We propose a correspondence between the physics of certain small charge black holes in AdSk × Sl and large charge black holes in AdSl × Sk. The curvature singularities of these solutions arise, following Myers and Tafjord, from a condensate of giant gravitons. When the number of condensed giants Ng is much greater than the number of background branes N , we propose that the system has an equiva...

Article history: Received 25 October 2011 Available online 4 November 2011 A meta-analysis of longitudinal studies was conducted to investigate stability and change in work values across the life span. Both rank-order stability and mean-level change were investigated using an integrative classification for intrinsic, extrinsic, social and status work values (Ross, Schwartz, & Surkis, 1999). Res...

Fossil bone collagen C dating and δC and δN isotopic measurements of the rodent Canariomys bravoi from Tenerife (Canary Islands, Spain) were used to test two different hypotheses about the causes of extinctions of endemic vertebrates on islands, climate versus humans. For the Tenerife giant rat, we show that it survived the climatic change that occurred between the Middle and Late Holocene, but...

AI Technologies are applicable to Homeland Security, particularly in problems of analysis, discovery and prediction. We describe relevant AI techniques including Link Analysis, dynamic Decision Support and Agent Organization modeling, whereby anomalous activities may be detected and threats deterred. We also discuss application of techniques in local government and to security matters close to ...
