The period since 2000 has been marked by numerous scandals in the corporate and political worlds. Dubious accounting practices and the illicit claiming of expenses by British MPs have become daily stories. At the same time, there has been growing scholarly interest in work practices at the other end of the business world, as in studies of various forms of worker 'resistance' (Ackroyd and Thomps...

The rapid time variation of mobile radio channels is often modeled as a random process with second order moments reeecting vehicle speed, bandwidth and the scattering environment. These statistics typically show that there is little room for prediction of channel properties such as received power or complex taps of the impulse response coeecients, at least when linear predictor structures are c...

This report presents the results of a limited evaluation of the block cipher MARS. No important weaknesses or flaws were found on MARS. The round function of MARS looks simple but is relatively complex to analyse because of the different natures of the involved components. MARS is an iterated cipher which runs in 32 rounds, but the rounds are not of the same type, which is somewhat unusual. The...

We describe the results of the first tests made on LISA, a simulator of planetary environments designed and built in Padua, dedicated to the study of the limit of bacterial life on the planet Mars. Tests on the cryogenic circuit, on the UV illumination and on bacterial coltures at room temperature that shall be used as references are described.

Sensitivity analysis (SA) is a commonly used approach for identifying important parameters that dominate model behaviors. We use a newly developed software package, a Problem Solving environment for Uncertainty Analysis and Design Exploration (PSUADE), to evaluate the effectiveness and efficiency of ten widely used SAmethods, including seven qualitative and three quantitative ones. All SAmethod...

The long-term future of life depends on expansion in space. In fact, pioneers such as Konstantin Tsiolkovsky [2], Robert Goddard, Freeman Dyson [3-6], Robert Forward [7], John D. Bernal [8], Michael Hart [9], and many others proposed technologies to expand life in space. Scientific plans exist for mining the asteroids[10, 11], settling Mars [12-14] and space colonies that could house billions [...

Although automation has advanced in manufacturing, the growth of automation in construction has been slow. Conventional methods of manufacturing automation do not lend themselves to construction of large structures with internal features. This may explain the slow rate of growth in construction automation. Contour Crafting (CC) is a recent layered fabrication technology that has a great potenti...

This paper seeks to predict efficiency ratings for Magic: The Gathering cards in the Draft format. This paper first uses reliable data gathered from the Magic community as the true efficiency ratings. Then, this paper discusses which of the available features are used and the reasoning behind using or not using a feature. This paper then examines a variety of regression algorithms to determine ...

Java is widely deployed on a variety of processor architectures. Consequently, an understanding of microarchitecture level Java performance is critical to optimize current systems and to aid design and development of future processor architectures for Java. Although this is facilitated by a rich set of processor performance counters featured on several contemporary processors, complex processor...
