This paper investigates the dynamic conditional correlations (DCC) of stock returns between China and international markets. Statistics suggest that stock-return correlations across markets are time-varying, displaying a structural change triggered by an upward shift in China’s adoption of financial liberalization and the occurrence of the worldwide financial crisis. The dynamic correlations ar...

We present a method for temporally consistent motion segmentation from RGB-D videos assuming a piecewise rigid motion model. We formulate global energies over entire RGB-D sequences in terms of the segmentation of each frame into a number of objects, and the rigid motion of each object through the sequence. We develop a novel initialization procedure that clusters feature tracks obtained from t...

This paper presents a system for overlaying 3D GIS data information such as 3D buildings onto a 2D physical urban map. We propose a map recognition framework by analysis of distribution of local intersections in order to recognize the area of the physical map from a whole map. The retrieval of the geographical area described by the physical map is based on a hashing scheme, which is called LLAH...

Now let (x, y, z) be a representative of a class in E and suppose z 6= 0 then (xz , y z , 1) is the unique representative of [(x, y, z)], the class of (x, y, z), in the plane z = 1. So we can think of projective points on E with nonzero z-coordinate as corresponding bijectively to solutions (x, y) of y = x + ax + b. Now suppose z = 0, then [(x, y, z)] ∈ E implies that x = 0, so there is exactly...

Winning business strategies are grounded in sustainable competitive advantage. A company has competitive advantage whenever it has an edge over rivals in securing customers and defending against competitive forces. There are many sources of competitive advantage: making the highest-quality product, providing superior customer service, achieving lower costs than rivals, having a more convenient ...

Introduction: Of Titan’s three seas, Kraken has the largest area, and sprawls over the widest range of latitude and longitude. This extent means it sees the largest variations in tidal accelerations due to Saturn’s gravity, and thus has the largest tides. New Cassini observations map the seas (figure 1) and allow quantification of tidal processes : a feature of particular interest is a narrow ‘...

I. Porteous has shown that the Cayley projective plane can be coordinatized in a way resembling homogeneous coordinates. We will show how to construct line coordinates in a similar way. As an illustration, we give an explicit example to show that the Cayley projective plane is not Desarguean.

Search is a ubiquitous behavior for a variety of species. Converging evidence from several domains suggests that there may be common principles that apply to search processes regardless of the species, or contexts, in which they are observed. Theories of cognitive or memory search have been motivated by findings in the animal foraging literature, and have recently been the subject of increased ...
