Various image enhancement algorithms are adopted to improve underwater images that often suffer from visual distortions. It is critical assess the output quality of undergoing algorithms, and use results optimise imaging systems. In our previous study, we created a benchmark for assessment via subjective experiments. Building on benchmark, this paper proposes new objective metric can automatica...

This paper presents JECho, a Java-based communication infrastructure for collaborative high performance applications. JECho implements a publish/subscribe communication paradigm, permitting distributed concurrent sets of components to provide interactive service to collaborating end users via event channels. JECho’s eager handler concept allows individual event subscribers to dynamically tailor...

Source code clones are copies or near-copies of other portions of code, often created by copying and pasting portions of source code. This working session is concerned with building a communal research infrastructure for clone detection. The intention of this working session is to try to build a consensus on how to continue to build a benchmark suite and results archive for cloneand source comp...

It is known that the performance of a genetic algorithm depends on the survival environment and the reproducibility of building blocks. In this paper, we propose a new encoding/crossover scheme that uses genic distance which explicitly de nes the distance between each pair of genes in the chromosome. It pursues both relatively high survival probabilities of more epistatic gene groups and divers...

In recent years Wireless Sensor Networks (WSNs) have enjoyed a growing amount of attention. One particularly promising prospect is to employ WSNs as an extension of the future internet into the real world; this motivates experimentally driven research to evaluate and benchmark new concepts on WSNs. With our poster we will show our approach to virtualizing Wireless Sensor Network testbeds. With ...

This paper studies the system optimum dynamic traffic assignment in a network consisting of a surface street grid and a congested freeway section. Vehicles can be diverted through off-ramps and on-ramps can be metered. The family of solutions are identified graphically using Newell’s queueing diagrams. Because enforcing diversion is still a technological puzzle, these results provide a benchmar...

Testing and debugging tools for concurrent programs are often validated on known bugs. To aid the development of these tools, we present the Race, Atomicity, and Deadlock Benchmark (RADBench) suite. The RADBench suite contains the full source of 10 real concurrency bugs found in large open-source software projects including Mozilla SpiderMonkey, Mozilla NSPR, Memcached, Apache Web Server, and G...

Developers often describe testing as being tedious and boring. Our work challenges this notion. We describe tools and methodologies crafted to test object-based storage devices (OSDs) for correctness and compliance with the T10 OSD standard. Special consideration is given to testing the security model of an OSD implementation. Some work was also carried out on building OSD benchmarks. This work...

Speech acts provide good insights into the communicative behavior of tweeters on Twitter. This paper is mainly concerned with speech act recognition in Twitter as a multiclass classification problem, for which we propose a set of word-based and character-based features. Inexpensive, robust and efficient, our method achieves an average F1 score of nearly 0.7 with the existence of much noise in o...

This report presents the results of a HECToR dCSE project to improve the performance of CP2K, a freely available and popular Density Functional Theory code, on HECToR. Building on a recently implemented domain decomposition method, further optimisation of the code was performed, and significant performance gains were measured around 30% on 256 cores (for a generally representative benchmark) an...
