Abstract:
This research proposes, implements and analyses a novel framework for multiobjective optimisation through evolutionary computing aimed at, but not restricted to, real-world problems in the engineering design domain. Evolutionary algorithms have been used to tackle a variety of non-linear multiobjective optimisation problems successfully, but their success is governed by key parameters which have been shown to be sensitive to the nature of the particular problem, incorporating concerns such as the number of objectives and variables, and the size and topology of the search space, making it hard

Discussing, defining and engaging with ‘terrorism’ has long been limited to the narrowly framed situations in which parties to an asymmetric conflict resort to the use of force and to the legitimacy they have in doing so. The problem with the limited understanding of ‘terrorism’ and ‘counterterrorism’ as ‘facts of objective reality’ is the lack of attention to the role of the extreme asymmetry of power in conflicts involving ‘terrorism’ that does not lend itself to analysis readily.

I define a network G = (V,E) composed of two parts: (i) the set of objects V, called nodes, and (ii) set of relationships (associations) E, called links, that connect objects in V.

Abstract:
Consumption of power and conservation of energy have become two of the biggest design challenges in construction of embedded systems. Energy is a resource in limited supply, but demands are increasing. Hence, much research is being performed to reduce power and energy usage or optimise performance under energy constraints. There are very few solutions that try to cater for the applications where the data input is not easily testable before run-time. These applications require an optimisation procedure that knows the power consumption of the system and is able to dynamically optimise operati

Abstract:
What usually goes unaddressed in the consultancy literature is an exploration of how consultants make sense of their contributions in particular when they come to work in politically laden contexts. Resulting conflictual debates with clients and colleagues severely influence how their advice is responded to. Against this background, consultants’ ability to determine and predict future outcomes of their work is hardly problematized. Additionally, consultants are mutually dependent on both colleagues and clients. This dependency underpins power differentials and the struggle which arises when th

Abstract:
Degree awarded (2004): DScCS, Computer Science, George Washington University<br>A common practice to save power and energy in embedded systems is to "put to sleep" or disable parts of the hardware. The memory system consumes a significant portion of the energy budget of the overall system, so it is a natural target for energy optimization techniques. The principle of software locality makes the memory subsystem an even better choice, since all memory blocks but the ones immediately required can be disabled at any given time. This opportunity is the motivation for developing energy optimization

Abstract:
Electro-hydrostatic Actuation Systems (EAS) successfully combine the advantages of electro-mechanical actuation - such as high-energy efficiency and low noise emission - with the benefits of electro-hydraulic technology –which include robustness and the precise handling of large forces. This paper defines keywords like EAS and Electro-hydraulic pump unit (EPU), and provides a comparison of the two technologies. Given the wide range of EAS technology topics, it is only possible to briefly introduce and discuss these in this paper. This technology has reached a level that renders it a strong mec
