Article Type: Full Length Research Article Microalgae have the potential to produce enough biofuels to meet current US fuel demands. In order to achieve this potential, photobioreactors (PBRs) that are efficient, scalable, and affordable need to be developed. Models are an analytical tool that can be used to evaluate various PBRs. In this article, a physics-based dynamic model was developed for...

The hypothesis that futures rates are unbiased and efficient predictors of future spot interest rates has been one of the most controversial topics in the empirical literature on market efficiency. The first part of this article concentrates on the question of whether the hypothesis that rates are unbiased holds for the 3-month Euribor futures market. The empirical analysis differs from usually...

We study the detection problem of finding planted solutions in random instances of flat satisfiability problems, a generalization of boolean satisfiability formulas. We describe the properties of random instances of flat satisfiability, as well of the optimal rates of detection of the associated hypothesis testing problem. We also study the performance of an algorithmically efficient testing pr...

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...

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...
