The paper investigates whether the classical socio-technical matrix that differentiate 4 quadrants of social-technical system: people, structure, tasks and technology can still be useful for practical purposes. The paper gives a positive answer on the question, provided that the level of abstraction in defining these four quadrants is increased to deal with culture, type of structure, methods (...

This paper explores the usefulness of the ‘ethical matrix’, proposed by Ben Mepham, as a tool in technology assessment, specifically in food ethics. We consider what the matrix is, how it might be useful as a tool in ethical decisionmaking, and what drawbacks might be associated with it. We suggest that it is helpful for fact-finding in ethical debates relating to food ethics; but that it is mu...

Two methods are given for the calculus of the fundamental matrix for the generalized linear differential equations on the Banach space of functions of bounded variation. The main result extends the Peano-Baker formula in this framework.

The widely used Total Variation de-noising algorithm can preserve sharp edge, while removing noise. However, since fixed regularization parameter over entire image, small details and textures are often lost in the process. In this paper, we propose a modified Total Variation algorithm to better preserve smaller-scaled features. This is done by allowing an adaptive regularization parameter to co...

On-chip communication architectures have a significant impact on the power consumption and performance of modern Multi-Processor System-on-Chips (MPSoCs). However, customization of such architectures for an application requires the exploration of a large design space. Thus designers need tools to rapidly explore and evaluate relevant communication architecture configurations exhibiting diverse ...

This paper addresses issue of sensitivity of efficiency classification of variable returns to scale (VRS) technology for enhancing the credibility of data envelopment analysis (DEA) results in practical applications when an additional decision making unit (DMU) needs to be added to the set being considered. It also develops a structured approach to assisting practitioners in making an appropria...

In this paper we consider the expected value function of a stochastic simple recourse program with random technology matrix and integer variables in the second stage. Due to its separability the analysis is straightforward. Conditions for finiteness, continuity, Lipschitz continuity and differentiability are derived by conditioning upon the technology matrix. The corresponding results for a fix...
