It has long been known that for certain narrowly defined problems, special-purpose processors can achieve significant cost/performance gains over general purpose machines. We describe one such processor here: a custom accelerator for gene sequence analysis,. The use of rapid prototyping technology was crucial in our efforts to produce a working system in a short amount of time. Field programmab...

This paper deals with quality assurance procedures for general-purpose language resources. Special attention is paid to quality control in wordnet development. General issues of quality management are tackled; technical as well as methodological aspects are discussed. As a case study, the application of the described procedures is demonstrated on the quality evaluation techniques in the context...

One of the important issues in designing a brain-computer interface system is to select the type of mental activity to be imagined. In some of these systems, mental activity varies with user intent and action that must be controlled by the brain-computer system, and in a number of other signals, the received signals contain the same activity-related mental activity that should be performed by t...

ReaderBench is a multi-purpose, multi-lingual and flexible environment that enables the assessment of a wide range of learners’ productions and their manipulation by the teacher. ReaderBench allows the assessment of three main textual features: cohesion-based assessment, reading strategies identification and textual complexity evaluation, which have been subject to empirical validations. Reader...

Real-time auralization of physical models has attracted vivid interest over the last years. This is mainly due to the rising computational capabilities of personal computers and the accessibility of specialized (external) accelerating hardware, like GPGPUs (generalpurpose graphics processing units) or FPGAs (field programmable gate arrays). In this work, an extended framework of real-time physi...

In the last years, recursive functions over the reals (Theoret. Comput. Sci. 162 (1996) 23) have been 9 considered, first as a model of analog computation, and second to obtain analog characterizations of classical computational complexity classes (Unconventional Models of Computation, UMC 2002, 11 Lecture Notes in Computer Science, Vol. 2509, Springer, Berlin, pp. 1–14). However, one of the op...

Any organization that develops software strives to improve the quality of its products. To do this first requires an understanding of the quality of the current product version. Then by iteratively making changes, the software can be improved with subsequent versions. But this must be done in a systematic and methodical way and for this purpose, we have developed a specific strategy called SIQi...

The goal of aspect-oriented programming is to modularize crosscutting concerns (or aspects) at the code level. These aspects can be defined in either a general-purpose language or in a language that is fine-tuned to a specific aspect in consideration. Aspect-specific languages provide more concise and more readable aspect declarations but are limited to a specific domain. Moreover, multiple asp...
