Annotation graphs provide an efficient and expressive data model for linguistic annotations of time-series data. This paper reports progress on a complete software infrastructure supporting the rapid development of tools for transcribing and annotating time-series data. This general-purpose infrastructure uses annotation graphs as the underlying model, and allows developers to quickly create sp...

Today, there are numerous software patterns for the software engineering of User Interfaces through interaction object classes that can be automatically retargeted to different graphical environments. Such methods are usually deployed in implementing multi-platform User Interface libraries, delivering Application Programming Interfaces (APIs) typically split in two layers: (a) the top layer, en...

This paper presents Tarsos 1 , a modular software platform to extract and analyze pitch and scale organization in music, especially geared towards the analysis of non-Western music. Tarsos aims to be a user-friendly, graphical tool to explore tone scales and pitch organization in music of the world. With Tarsos pitch annotations are extracted from an audio signal that are then processed to form...

Scientific Workflow Systems have been developed as a means to enable scientists to carry out complex analysis operations on local and remote data sources in order to achieve their research goals. Systems typically provide a large number of components and facilities to enable such analysis to be performed and have matured to a point where they offer many complex capabilities. This complexity mak...

This paper explores the characteristics of DataCite to determine its possibilities and potential as a new bibliometric data source to analyze the scholarly production of open data. Open science and the increasing data sharing requirements from governments, funding bodies, institutions and scientific journals has led to a pressing demand for the development of data metrics. As a very first step ...

Different types of users require different functions in NLP software. It is difficult for a single platform to cover all types of users. When a framework aims to provide more interoperability, users are required to learn more concepts; users’ application designs are restricted to be compliant with the framework. While an interoperability framework is useful in certain cases, some types of users...

The purpose of the PAPI project is to specify a standard API for accessing hardware performance counters available on most modern microprocessors. These counters exist as a small set of registers that count "events", which are occurrences of specific signals and states related to the processor's function. Monitoring these events facilitates correlation between the structure of source/object cod...

Renewable energy resources, such as photovoltaic panels, typically have very volatile power-injection characteristics, which poses a number of challenges to the real-time control of electrical grids that contain a significant fraction of these resources. Recently, a new paradigm for controlling such grids, termed COMMELEC, was proposed; it uses explicit power setpoints instead of droop-control....

For this poster, the usability of the two most common IO libraries for parallel IO was evaluated, and compared against a pure MPI-IO implementation. Instead of solely focusing on the raw transfer bandwidth achieved, API issues such as data preparation and call overhead were also taken into consideration. The access pattern resulting from parallel IO in unstructured grid applications, which is a...

We describe the design, implementation, and deployment of the Comprehensive Extensible Data Documentation and Access Repository (CED2AR). This is a metadata repository system that allows researchers to search, browse, access, and cite confidential data and metadata through either a web-based user interface or programmatically through a search API, all the while re-reusing and linking to existin...
