Recent developments in speech, network and embedded-computer technologies indicate that human-computer interfaces that use speech as one or the main mode of interaction will become increasingly prevalent. Such interfaces must move beyond simple voice commands to support a dialogue-based interface if they are to provide for common requirements such as description resolution, perceptual anchoring...

This paper presents an in-depth analysis of Intel’s Haswell microarchitecture for streaming loop kernels. Among the new features examined is the dual-ring Uncore design, Cluster-on-Die mode, Uncore Frequency Scaling, core improvements as new and improved execution units, as well as improvements throughout the memory hierarchy. The Execution-Cache-Memory diagnostic performance model is used toge...

This paper experimentally investigates how GPUs execute instructions when used for general purpose computing (GPGPU). We use a light-weight realizing a vector operation to analyze which vector entries are updated subsequently, and identify regions where parallel execution can be expected. The results help us to understand how GPUs operate, and map this operation mode to the mathematical concept...

This paper presents two proposed approaches to color image decomposition with Bidimensional Empirical Mode Decomposition (BEMD) technique. The first one applies the BEMD on each channel separately and the second is based on interpolation of each channel in the sifting process. The application of the two methods shows the same performance of each approach in terms of PSNR and visual quality, but...

This paper presents two different approaches in color image decomposition domain with Bidimensional Empirical Mode Decomposition (BEMD). The first approach applies the BEMD on each channel separately and the second is based on interpolation of each channel in the sifting process. The comparison of two approaches shows the same performance of each approach in terms of visual quality, but they do...

We introduce Mercury, a new purely declarative logic programming language designed to provide the support that groups of application programmers need when building large programs. Mercury's strong type, mode and determinism systems improve program reliability by catching many errors at compile time. We present a new and relatively simple execution model that takes advantage of the information t...
