Various works have used word alignments in parallel corpora to transfer information like POS tags, syntactic trees and word senses from source to target sentences. In this paper, we work on the problem of projecting s...

the integral histogram is a recently proposed preprocessing technique to compute histograms of arbitrary rectangular gridded (i.e. image or volume) regions in constant time. We formulate a general parallel version of the the integral histogram and analyse its implementation in Star Superscalar (StarSs). StarSs provides a uniform programming and runtime environment and facilitates the development of portable code for heterogeneous parallelarchitectures. In particular, we discuss the implementation for the multi-core IBM Cell Broadband Engine (Cell/B.E.) and provide extensive performance measurements and tradeoffs using two different scan orders or histogram propagation methods. For 640 x 480 images, a tile or block size of 28 x 28 and 16 histogram bins the parallel algorithm is able to reach greater than real-time performance of more than 200 frames per second.
In this paper we present our results in adapting a Spiking Neural P system (SNP system) simulator to a high performance graphics processing unit (GPU) platform. In particular, we extend our simulations to larger and m...

the implementation of a complex, large vocabulary, speech recognition application on a modern graphic processors (GPUs) is presented. the parallel single instruction, multiple data (SIMD) architecture is effectively exploited by performing various optimizations to expose the algorithmic parallelism. the work addresses particularly the realization of the Gaussian calculation, a key function. the result is an implementation that runs 3.75 faster than real-time and gives a tenfold speedup when compared to a highly optimized sequential CPU-based implementation. the work is also compared with some earlier work involved in building the same system on a Virtex 5-based, Alpha Data XRC-5T1 reconfigurable computer.

In this paper, we present an Information Service designed for maintaining resource information in Cloud datacenters. We employ a P2P cluster of super-peers that share the resource information and load of related activities in a Distributed Hash Table (DHT) based manner. Our DHT does not employ the standard keyspace range-partitioning, but implements more complicated algorithm to enable better distribution and fault-tolerance in the Cloud datacenter context. We implement a prototype of the proposed system and conduct comparative measurements that illustrate its scalable and fault-tolerant capabilities.

Recent turmoil in financial markets has invoked governments to monitor activities and transactions in the private sector more strictly. At the same time, policy makers strive to cut back on government spending by reducing the size of government agencies. these contradicting developments require governments to become leaner, meaning that more (new) tasks can be performed with fewer resources. In order to achieve these goals, we see a transformation from paper-based business-to-government information exchange to IT-enabled compliance architectures. However, the shape of these architectures is not yet clear, as are the challenges that come with a specific architecture design. the objective of this paper is to specify the dimensions of IT-enabled compliance architectures and the challenges that rise when transforming to such architectures. Drawing on dimensions described in literature, this paper compares two new compliance architectures, one in the meat processing industry and one in financial reporting. Findings indicate that compliance architectures require different choices regarding the frequency of reporting, the style of control, the formation of regulation, the type of dependencies, the auditing base and the way the underlying infrastructure accommodates business-to- government information exchange. this paper shows that while the transformation to IT-enabled compliance monitoring helps realize a lean-government, the design of the underlying architectures is subject to several, sector specific conditions, including established laws and regulations.
