The concept of alliance or preferably ‘alignment’, as I shall explain below – is central to the conduct of international politics, and thus the discipline of International Relations (IR). Duffield et al. (2008: 291) identify that ‘Alliances are one of the most significant phenomena in security studies and world politics more generally’, while Modelski (1963: 773) considers them ‘one of a dozen ...

In this article I locate some of the fundamental problems of self-determination within the context of an evolving international society. First, I argue that one particular manifestation of self-determination, that of national self-determination, is both a solution to the enduring problem of territorial legitimation in international relations as well as the source of subsequent challenges to ter...

Historically, issues of gender, race and the environment have received little attention in mainstream International Relations (IR) scholarship. Great strides have been made, however, in interrogating the inadequacies of the field in these areas and, similarly, in demonstrating the necessity of expanded definitions of security and violence in IR. Despite these strides, mainstream environmental s...

Linear time-invariant networks are modelled by linear differential-algebraic equations with constant coefficients. These equations can be represented by a matrix pencil. Many publications on this subject are restricted to regular matrix pencils. In particular, the influence of the Weierstrass structure of a regular pencil on the poles of its inverse is well known. In this paper we investigate s...

Background There are obvious problems involved in the accurate description of movement of the intrinsic bones within the foot and ankle. The 26 small bones are difficult, if not impossible to individually represent with standard skin mounted markers for motion analysis [1,2]. This international research collaboration has performed a number of studies in which invasively inserted intracortical p...

An in-silico assessment of the performance of 3D video-fluoroscopy for the analysis of the kinematics of long bones is proposed. A reliable knowledge of in-vivo joints kinematics in physiological conditions is fundamental in the clinical field. 3D videofluoroscopy theoretically permits a mm/deg level of accuracy in joint motion analysis, but the optimization algorithm for the pose estimation is...

We give a monoid presentation in terms of generators and defining relations for the partial analogue of the finite dual inverse symmetric monoid. AMS 2000 Mathematical Subject Classification 20M05, 68R15, 20M20.

231  Abstract—The kinematic of serial manipulators comprises the study of the relations between joint variables and Cartesian variables. We distinguish two problems, commonly referred to as the direct and inverse kinematic problems. The former reduces matrix multiplications, and poses no major problem. The inverse kinematic problems, however, is more challenging, for it involves intensive vari...

The state plays a central position in theoretical debates in International Relations (IR). Both Realists and Liberals see the state as the central actor in the international system and thereby follow a Western understanding of the state as the holder of the monopoly of force. In the IRsub discipline of security studies new categories such as weak state, quasi state or state failure have created...
