When moving through cluttered environments we use different forms of the same source of information to avoid stationary and moving objects. A stationary obstacle can be avoided by looking at it, registering the differential parallactic displacements on the retina around it during pursuit fixation, and then acting on that information. Such information also specifies one's general heading. A movi...

Background Materials choice has long been recognized as a key factor in realizing the full safety and environmental potential of fusion power. Because the materials are de-coupled from the fusion energy source (the plasma), the long-term neutron-induced activation of components can be tailored by proper selection of materials to avoid generation of waste that would require deep geological dispo...

The aim of this paper is, on the one hand, to critically investigate Kuhn’s stance on the assessment of the pursuit worthiness of scientific theories, and, on the other hand, to show the actuality of some of Kuhn’s points on this issue, in view of their critical analysis. To this end we show that Kuhn presents certain tools, which may help scientists to overcome communication breakdowns when en...

Bidders on eBay frequently engage in sniping: submitting a bid seconds before the end of the auction. In this paper, we use a field experiment to measure the size of the benefit obtained by a bidder who snipes rather than bidding early. Previous research by Roth and Ockenfels (2002) documents the extent of this sniping. We identified pairs of identical items sold by the same seller and ending n...

Resistance of wood reacted in situ with phosphorus pentoxide-amine to the brown-rot fungus Gloeophyllum trabeum and white-rot fungus Trametes versicolor was examined. Wood reacted with either octyl, tribromo, or nitro derivatives were more resistant to both fungi. Threshold retention values of phosphoramide-reacted wood to white-rot fungus T. versicolor ranged from 2.9 to 13.3 mmol, while these...

Over half of the total electricity consumption is used in buildings. Air-conditioning and electric lighting are the two main resources of electricity consumption in high rise buildings. One way to reduce electricity consumption would be to limit heat gain into buildings, therefore reduce the demand for air-conditioning during hot summer months especially in hot regions. On the other hand natura...

Fatigue is a common problem in rheumatoid arthritis (RA), experienced by the majority of patients, with fatigue scores that are often higher than pain scores [1,2]. Despite this, patients feel fatigue has been largely ignored by clinicians. This article provides a personal overview of the journey of RA fatigue from ‘nonexistence’ to ‘hot topic’ and looks toward a time when fatigue might return ...

In recent years sustainability has become a ‘hot topic’ and something al organisations want to be seen as being identified with. The twin disciplines of quality and HRM have joined this bandwagon. In HR terms this has meant a shift in emphasis away from human management to resource management with the argument that organisations need to allow the needs and aspirations of individuals to be place...

Pursuit formation control of double-integrator Multi-Agent Systems (MASs) is considered in this paper. To achieve a formation, a hierarchical control scheme is proposed in two layers. In the first layer, in a leaderless architecture, each agent pursues another one in a cyclic topology to achieve a regular polygon formation around a centroid, namely, pursuit centroid, and in the second layer, th...
