Fact: Blue images always look sharper than white images to the user. Siemens Display Technologies implemented blue backlights in its flat panel display product line and had the same feedback from its customers: bluish pictures look brighter. Therefore we wanted to research this theme and try to explain this unique “feature” from a more theoretical point of view. We can explain why, under interi...

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 50+. The human capital framework suggests that retirement may cause an increase in cognitive dec...

Photon detectors are indispensable in many areas of fundamental physics research, particularly in the emerging field of particle astrophysics, as well as in medical imaging and nuclear non-proliferation. For a significant progress in all these areas a new, inexpensive industrial massproduction photosensor technology is needed. In order to reach that goal we have introduced several innovations. ...

-------------------------------------------------------------------------------------------------------------------Abstract: We investigate the long run consequences of infrastructure provision on per capita income in a panel of countries over the period 1950-1992. Simple panel based tests are developed which enable us to isolate the sign and direction of the long run effect of infrastructure o...

The recent LIBOR scandals have demonstrated that the panel banks did not report in good faith, leading some to question whether LIBOR was ever accurate. This article derives the equilibrium LIBOR reporting strategy and quantifies the LIBOR bias. It finds that the current trimming mechanism cannot prevent LIBOR rigging, although the LIBOR gets less biased when the cross-sectional dispersion of t...

In this paper we investigate the impact of colorimetric observer categories on the prediction of the average suprathreshold color difference perception. The observer categories were obtained from an observer classification experiment, while the color difference data were obtained from an experiment involving a liquid crystal display (LCD) with fluorescent backlight. The same observer panel with...

1Advanced Computing Research Centre, University of South Australia, Mawson Lakes, South Australia 5095 {Phillip Lock. [email protected]} Abstract. Game playing in immersive projection environments such as caves and domes is assumed to offer an enhanced experience but there is little quantitative research that measures this. This paper reports on a study of user performance statistics wh...

In this paper, we will introduce two different three dimensional VR-based user interface for telecommunication network management. The first one is an immersive system, using HMD and other 3D input devices. The other is a WWW-based flat screen 3D collaborative user interface. The architecture of each system and our observation from it will be described. Then, a comparison will be made to show t...

Folding of flat sheets of material into intricate three-dimensional structures provides a new technology for production of cores and sandwich structures of high strength/weight and/or strength/volume ratios. Geometric patterns are generated by transforming flat sheets of materials (traditional or composite) by imposing a permanent fold at specific edges of tessellated sheets. This might result ...

Nowadays there are several grid connected converter in the grid system. These grid connected converters are generally the converters of renewable energy sources, industrial four quadrant drives and other converters with DC link. These converters are connected to the grid through a three phase bridge. The standards prescribe the maximal harmonic emission which could be easily limited with high s...
