The level set representation of shapes is useful for shape evolution and is widely used for the minimization of energies with respect to shapes. Many algorithms consider energies depending explicitly on the signed distance function (SDF) associated with a shape, and differentiate these energies with respect to the SDF directly in order to make the level set representation evolve. This framework...

Clustered voltage scaling scheme is an effective method of power consumption reduction without performance degradation. One of the main issues in this scheme is performance and power penalties due to insertion of level converting flip-flops at the interface from low-supply to high supply clusters to simultaneously perform latching and level converting functions. A new level converting flip-flop...

Multi-supply voltage design using Cluster Voltage Scaling (CVS) is an effective way to reduce power consumption without performance degradation. One of the major issues in this method is performance and power overhead due to insertion of Level Converting Flip-Flops (LCFF) at the interface from lowsupply to high-supply clusters to simultaneously perform latching and level conversion. In this pap...

We propose a novel technique for web search personalization that exploits the clustering of the results of web searches. Our approach is based on an automatic characterization of the user search history through the collection of semantic domains and web sources chosen by the user. The semantic domains are the terms extracted directly from the clusters contents which describe the main topics cov...

PGF (Portable Grammar Format) is a low-level language used as a target of compiling grammars written in GF (Grammatical Framework). Low-level and simple, PGF is easy to reason about, so that its language-theoretic properties can be established. It is also easy to write interpreters that perform parsing and generation with PGF grammars, and compilers converting PGF to other format. This paper gi...
