We investigate the relationship between ageing, cognitive abilities and retirement using the Survey on Health, Ageing and Retirement in Europe (SHARE), a household panel that offers the possibility of comparing several European countries using nationally representative samples of the population aged 50þ . The human capital framework suggests that retirement may cause an increase in cognitive de...

Digital radiography is earning its place in the NDT market, as specialists realize this technology surpasses Film and Film Replacement. Portable digital Radiography provides many benefits to users. Fast images upon request for immediate analysis mean there is no compromise on image quality and no repositioning. Vidisco flat panel systems enable the reduction of working time and costs while enla...

Current consumer-level priced and state-of-the-art scanrate converters enable a spatio-temporal decoupling of the received video and the displayed video. This paper presents the results of a subjective assessment indicating the preferred CRT-display format.

While most market transactions are subject to strong incentives, transactions within firms are often not incentivized. We offer an explanation for this observation based on envy among agents in an otherwise standard moral hazard model with multiple agents. Envious agents suffer if other agents receive a higher wage due to random shocks to their performance measures. The necessary compensation f...

For large sized glass handling robot, reliability improving activity increases the importance. The activity is divided into two phases of design phase and line usage phase. At the design phase, accurate simulation for keeping the limitation of material or gear strength and accurate torque control are the key. At the line usage phase, supporting tool for preventive maintenance activity is the ke...

Flat transactions with savepoints are a variation of the classical flat transactions that allows the user to go undo work done so far back to a certain point within the transaction. This is as opposed to pure classical flat transactions that either commit to whole work done so far or undo it. Recently, this mechanism is being offered by some major database products. Their semantics, however, se...

Artifacts and surfaces that can display digital content are proliferating at a steady rate. Many of these displays will be peripheral, i.e., used for content that is not directly related to one’s primary activities. However, what kinds of content would people want to see on such peripheral displays? We have begun to investigate the use of peripheral displays in three workplace contexts: within ...

The radiation efficiency of an infinite flat panel which is radiating an infinite plane wave into an infinite half space can be shown to be equal to the inverse of the cosine of the angle between the direction of propagation of the plane wave and the normal to the panel. The fact that this radiation efficiency tends to infinity as the angle tends to 90° causes problems with simple theories of s...

The simple aerial display system called holographic pyramid has been eliciting much attention recently. However, the image that appears to be floating in the pyramid has no depth information because it is merely a virtual image of a 2D image displayed on a flat-panel display and reflected at the surface of a transparent board of the pyramid. Therefore, we propose a new holographic pyramid syste...
