With the unfolding shift of global geostrategic gravity centers as a result of the rise of emerging powers like China and India, America's strategic priorities are shifting too, that is, away from such "quagmires" as the Middle East and more towards the Asia Pacific, Eurasia and the Arctic. The United States thus seeks to disengage from the Middle East, which means it is no longer as worried about

Reconstruction from Three Images of Six Point Objects

Abstract. This paper deals with the problem of reconstructing the locations of six points in space from three different images. It is assumed that the correspondences between the points in the different images are known. This paper shows that there are in general three solutions to the problem of determining the shape of the object, but some of them may be complex and some may not be physically re

Recommendations for Speed Management Strategies and Policies.

The aim of the project MASTER (MAnaging Speeds of Traffic on European Roads) was to produce information that can be cited in the preparation of national and EU decisions concerning speed management and speed control equipment standards. For this purpose, the project looked for answers to three key questions: 1)What are acceptable ranges of speeds? 2)What are the key factors influencing drivers’ ch

The Molecular Evolution of Snakes as revealed by Mitogenomic Data

Snakes (Serpentes) are a diverse suborder of reptiles that, along with lizards and amphisbaenians, belong to the reptilian order Squamata. The phylogenetic position of snakes relative to lizards and amphisbaenians has been debated for about 140 years. Despite the many morphological and molecular studies that had been done, no consensus had been reached as to the phylogenetic position of snakes or

Fault Behaviour of Wind Farms with Fixed-Speed and Doubly-Fed Induction Generators

Abstract in UndeterminedThis paper focuses on the fault current contribution of wind farms with Fixed-Speed (FSIG) and Doubly-Fed Induction Generators (DFIG). The fault current delivered by a single FSIG during both symmetrical and unsymmetrical faults is found analytically and validated through simulations. Simulations of a detailed model of a wind farm with several FSIG or DFIG are then performe

Max-Min Fair Optimization Models in Network Design

Max-min fairness (MMF) is a general objective of multi-criteria optimization with important and natural applications in communication network design. The notion of MMF and optimization models involving MMF seem not to be commonly known to network designers and therefore they are not used to an extent they deserve. Moreover, the MMF approaches are sometimes “reinvented”, in some cases not correctly
