We present an architecture and software framework for semantic allies: Semantic systems that complement existing software applications with semantic services and interactions based on a background ontology. On the one hand, our Semantic Alliance framework follows an invasive approach: Users can profit from semantic technology without having to leave their accustomed workflows and tools. On the ...

In this paper we present the MyMultimediaWorld Internet-based platform designed to benchmark descriptors and description scheme for 3D object retrieval purpose. Relying on the MPEG-4 and MPEG-7 multimedia standards for data representation and description respectively, this open platform is designed to host multiple datasets, descriptors, descriptor extraction algorithms and similarity measures....

FPGA overlays are commonly implemented as coarse-grained reconfigurable architectures with a goal to improve designers’ productivity through balancing flexibility and ease of configuration of the underlying fabric. To truly facilitate full application acceleration, it is often necessary to also include a highly efficient processor that integrates and collaborates with the accelerators while mai...

 SEMATECH, a US based consortium of ten major semiconductor manufacturers, is developing a comprehensive system for the design of ICs below .25 μm, which exploits hierarchy, constraint directives, incremental processing, and concurrent design and analysis. This development of SEMATECH's Chip Hierarchical Design System (CHDS) includes major technological investments in algorithms for design pla...

PortAudio is an open source 'C' language API and library for implementing cross-platform real-time audio applications. This paper describes recent additions to the PortAudio API designed to assist in implementing synchronisation between real-time audio and other time-based data such as MIDI and computer graphics. Examples are presented that illustrate synchronisation of a graphical display to r...

Healthcare workers continue to operate in challenging environments when assessing and treating patients in low and middle-income countries (LMIC). These difficulties are exacerbated when it comes to the assessment of infant vital signs e.g. pulse, blood pressures. As part of the EU funded Supporting LIFE project, our aim is to develop a Mobile Health (mHealth) Android application with Wearable ...

The default messaging model for the OpenFabrics “Verbs” API is to consume receive buffers in order—regardless of the actual incoming message size—leading to inefficient registered memory usage. For example, many small messages can consume large amounts of registered memory. This paper introduces a new transport protocol in Open MPI implemented using the existing OpenFabrics Verbs API that exhib...

Consistently growing architectural complexity and machine scales make creating accurate performance models for large-scale applications increasingly challenging. Traditional analytic models are difficult and time-consuming to construct, and are often unable to capture full system and application complexity. To address these challenges, we automatically build models based on execution samples. W...

Motivation In many key applications in the field of metabolomics, such as toxicology or nutrigenomics, it is of interest to profile and detect physiological changes in metabolic pathways. For this purpose, it is useful to build a comprehensive graphical representation which shows metabolic processes occurring in an organism using networks. To model these systems it is possible to describe both ...

approved: ______________________________________________________ Christopher Scaffidi Application Programming Interfaces (APIs) enable software developers to utilize and create functionality that would otherwise take a lot of time and effort to build from scratch. Consequently, an essential part of software engineering training is for students to learn how to use APIs effectively. The existing ...
