Any bipartite Eulerian graph, any Eulerian graph with evenly many vertices, and any bipartite graph with evenly many vertices and edges, has an even number of spanning trees. More generally, a graph has evenly many spanning trees if and only if it has an Eulerian edge cut. ∗Work supported in part by NSF grant CCR-9258355 and by matching funds from Xerox Corp.

Measuring the effectiveness of sharia banking organizations is now even more crucial due to expanding popularity worldwide and in Indonesia particular. The ability maximize resources under their control will undoubtedly be determined by efficiency measurement. In other words, a company's productivity increase with increased efficiency. Data Envelopment Analysis (DEA) idea, which measures busine...

One of the major challenges in denotational semantics is the construction of a fully abstract semantics for a higher-order sequential programming language. For the past fifteen years, research on this problem has focused on developing a semantics for PCF, an idealized functional programming language based on the typed λ-calculus. Unlike most practical languages, PCF has no facilities for observ...

Mosaicing and super resolution are two ways to combine information from multiple frames in video sequences. Mosaicing displays the information of multiple frames in a single panoramic image. Super-resolution uses regions which appear in multiple frames to improve resolution and reduce noise. The aim of this work is constructing a high resolution mosaic from a video sequence in an efficient way....

Power MOSFET technology has developed toward higher cell density for lower on-resistance. The super-junction device utilizing charge balance theory was introduced to semiconductor industry ten years ago and it set a new benchmark in the high-voltage power MOSFET market [1] . The Super-Junction (SJ) MOSFETs enable higher power conversion efficiency. However, the extremely fast switching performa...
