Processing tabular data holds significant importance across various domains and applications. This study investigates the performance and limitations of fine-tuned models for tabular data analysis, specifically focusing on using fine-tuning mechanics on an English model towards a potential German model. The validation of the effectiveness of the tr...

Within the Mobility Choices (MC) project we have developed an app that allows users to record their travel behavior and encourages them to try out new means of transportation that may better fit their preferences. Tracks explicitly released by the users are anonymized and can be analyzed by authorized institutions. For recorded tracks, the freely a...

With Cloud Computing and multi-core CPUs parallel computing resources are becoming more and more affordable and commonly available. Parallel programming should as well be easily accessible for everyone. Unfortunately, existing frameworks and systems are powerful but often very complex to use for anyone who lacks the knowledge about underlying conce...

Optimization with the Distributed Execution Framework

There is high demand for library routines that can be included into arbitrary programs and executed in parallel in the Cloud. So our approach is to provide a framework that supports the parallelized execution of library routines, written in different programming languages, from any platform. Our Distributed Execution Framework (DEF) allows to (1) d...

An application’s user documentation, also referred to as the user manual, is one of the core elements required in application distribution. While there exist many tools to aid an application’s developer in creating and maintaining documentation on and for the code itself, there are no tools that are complementing code development with user document...

An application's user documentation, also referred to as the user manual, is one of the core elements required in application distribution. While there exist many tools to aid an application's developer in creating and maintaining documentation on and for the code itself, there are no tools that complement code development with user documentation f...

Automated generation of application documentation targeted to the end user is sparsely investigated. This is partly due to the fact that, up to now, no application model existed, providing the required comprehensive information about the application. The new generation of Eclipse based Rich Client Platform applications is developed on the basis of...

Due to the recent explosion of research data based on novel scientific instruments and corresponding experiments, automatic features, in particular in data analysis, has become more essential than ever. In this paper we present a new Automatic Analysis Framework (AAF) that is able to increase the productivity of data analysis. The AAF can be used f...

This paper introduces the advanced breath analysis (ABA) platform, an innovative scientific research platform for the entire breath research domain. Within the ABA project, we are investigating novel data management concepts and semantic web technologies to document breath analysis studies for the long run as well as to enable their full automatic...

In this paper we present a novel Code Execution Framework that can execute code of different problem solving environments (PSE), such as MATLAB, R and Octave, in parallel. In many e-Science domains different specialists are working together and need to share data or even execute calculations using programs created by other persons. Each specialist...

In this paper we present a novel dataspace-based support platform for the international breath gas analysis community, which consists of over 30 institutions world wide with rapidly expanding research studies in various application domains. The work discussed in this paper is mainly consolidated of two independently targeted frameworks: a data life...

In this paper we present a novel Kerberos-based security concept for heterogeneous distributed e-Science infrastructures. The e-Science infrastructure we have recently developed is currently being tested by the breath gas analysis community, whose activities are based on large-scale collaborations. In many e-Science domains personal related data (e...

Sharing data within Grid environments can potentially result in losing control over data usage. If the shared information is medical data laws must be followed, enabling tightly controlled, reconstructible access. To comply with these regulations it must be guaranteed, that each data access and modification is recorded to enable audit trails. The p...

Scientific dataspaces aim at providing associated mechanisms for managing semantically rich relationships among scientific data sources (primary data) and its corresponding findings (derived data). The latter result from a set of activities defining concrete preprocessing and analysis methods (background data) that were applied to a source dataset....

Sharing data within grid environments always results in losing control over data usage. If the shared information is medical data, this violates laws as specified in HIPAA, because access to such data must be reconstructible and needs to be tightly controlled. To comply with these regulations it must be guaranteed, that each data access and modific...

Cloud computing allows delivering information technology power on demand. Be it either the hosting of a certain Web application or the outsourcing of an entire server or data center by means of virtualization. Applying these techniques however goes along with handing over the ultimate control of data to a third party. This paper investigates the ap...

Within the Austrian Grid project phase 2, three different groups, each allocated to a different work package, join their efforts to implement a grid infrastructure for the european research project "Breath Gas Analysis for molecular oriented diseases''. This position paper provides background on the task and the resulting requirements, a presentati...

In 2003, MIT Technology Review listed Grid computing as one of 'Ten Emerging Technologies That Will Change the World' [5]. Five years later, is Grid computing ready for the undergraduate classroom? In this panel, a group of educators share their experiences in teaching Grid computing over the past several years and in various settings, and discuss...
