In this paper, we present for the first time efficient explicit formulas for arithmetic in the degree 0 divisor class group of a real hyperelliptic curve. Hereby, we consider real hyperelliptic curves of genus 2 given in affine coordinates for which the underlying finite field has characteristic > 3. These formulas are much faster than the optimized generic(More)
We present an optimization framework for generating diverse variations of physics-based character motions. This allows for the automatic synthesis of rich variations in style for simulated jumps, flips, and walks. While well-posed motion optimization problems result in a single optimal motion, we explore using underconstrained motion descriptions and then(More)
For multiple-input multiple-output wireless systems, we investigate the important question of how many antennas to place in fixed-length arrays, accounting for both spatial correlation and mutual coupling at the transmitter and receiver. We show that there is an optimal antenna configuration yielding the highest capacity which depends strongly on the array(More)
We present an optimization framework that produces a diverse range of motions for physics-based characters for tasks such as jumps, flips, and walks. This stands in contrast to the more common use of optimization to produce a single optimal motion. The solutions can be optimized to achieve motion diversity or diversity in the proportions of the simulated(More)
Web content quality assessment is a typical static ranking problem. Heuristic content and TFIDF features based statistical systems have proven effective for Web content quality assessment. But they are all language dependent features, which are not suitable for cross-language ranking. In this paper, we fuse a series of language-independent features(More)
In Internet of Things (IoT), both physical things (such as devices, gateways and commodities etc.) and virtual things (like multimedia content and application software) are assigned unique IoT identifiers (IoT ID), which are similar to the domain name used for locating online resources in Internet. However, until now the format of IoT ID is not globally(More)
The inevitability of IPv6 has come to fore. How to resolve the problem of IP address registration has been a great challenge for network management. The existing solution uses manual registration mechanism, not suitable for dealing with massive IPv6 addresses. Based on the Extensible Provisioning Protocol, we propose an “EPP-IP” mechanism to(More)
The rapid development of cloud computing has made traditional data centers energy hungry. Thus it is very important to reduce the amount of calculations on the cloud. In this paper we focus on the energy saving in cloud storage service. First we analyze rsync algorithm widely used in the cloud synchronization service and reveal how this algorithm will lead(More)
