For decades, performance comparisons between real estate and financial assets have repeatedly indicated that private real estate investment exhibits significantly higher risk-adjusted returns than publicly traded financial assets such as common stocks. That is, there is an apparent “real estate risk premium puzzle.” In this paper, we find that the seemingly superior risk-adjusted returns of rea...

IMMIView is an interactive system that rely on multiple modality and multi-user interaction to support collaborative design review. It was designed to offer natural interaction in visualization setups such as large scale displays, head mounted displays or TabletPC computers. To support architectural design, our system provides content creation and manipulation, 3D scene navigation and annotatio...

Real solution classification of parametric polynomial systems is a crucial problem in real quantifier elimination which interests Volker Weispfenning and others. In this paper, we present a stepwise refinement algorithm for real solution classifications of a class of parametric systems consisting of polynomial equations, inequalities and inequations. For an input system, the algorithm outputs t...

Current graphics processors are very slow for displaying shaded 3D objects. A lot of work is being done in order to define faster display processors by using massive parallelism and VLSI components. Our proposal goes along this line with the supplemen­ tary aim of displaying images in real time, i.e., 25 or 30 times per second. We choose to design a graphics module without any working memory an...

This paper presents an efficient video filtering scheme and its implementation in a field-programmable logic device (FPLD). Since the proposed nonlinear, spatiotemporal filtering scheme is based on order statistics, its efficient implementation benefits from a bit-serial realization. The utilization of both the spatial and temporal correlation characteristics of the processed video significantl...

Despite the widespread importance of aqueous bicarbonate chemistry, its conjugate acid, carbonic acid, has remained uncharacterized in solution. Here we report the generation of deuterated carbonic acid in deuterium oxide solution by ultrafast protonation of bicarbonate and its persistence for nanoseconds. We follow the reaction dynamics upon photoexcitation of a photoacid by monitoring infrare...

This paper addresses optimization issues in fuzzy model-based predictive control. The success of linear predictive control in controlling constrained linear processes is mainly due to the fact that the on-line optimization problem is a convex one, usually a quadratic programme. When the process model is nonlinear fuzzy one, non-convex time consuming optimization is necessary, with no guarantee ...

the main goal of this note is to introduce another second-order differenceequation where every nontrivial solution is of minimal period 5, namelythe difference equation:xn+1 =1 + xn−1xnxn−1 − 1, n = 1, 2, 3, . . .with initial conditions x0 and x1 any real numbers such that x0x1 6= 1.
