Cloud computing allows delivering information technology power on demand. Be it either the hosting of a certain Web application or outsourcing an entire server data center by means virtualization. Applying these techniques however goes along with handing over ultimate control to third party. This paper investigates Nimbus as cloud resource and shows example implementation for retaining user based virtual machine images encrypted client side. that procedures involved verifying validity...

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. many e-Science domains specialists are working together need to share data or even calculations using programs created by other persons. Each specialist may use environment therefore the collaboration become quite difficult. Our framework supports cloud platforms, Amazon Elastic Compute Cloud (EC2) Eucalyptus. Therefore it...

In this paper we show how the technologies associated with evolution of Cloud computing to Dew can contribute advancing scientific computational productivity through automation. current big data paradigm developments, there is growing trend towards automation mining and other analytical processes involved in science increase applications. There are already several efforts create automated platforms. However, these platforms prevalently oriented business engineering application domains. This...

In this paper we present a novel Kerberos-based security concept for heterogeneous distributed e-Science infrastructures. The infrastructure have recently developed is currently being tested by the breath gas analysis community, whose activities are based on large-scale collaborations. many domains personal related data (e.g. patient data) involved and therefore privacy very important. Several publications mentioned that it straightforward to add additional an existing means of Kerberos. Our...

There is high demand for library routines that can be included into arbitrary programs and executed in parallel the Cloud. So our approach to provide a framework supports parallelized execution of routines, written different programming languages, from any platform. Our Distributed Execution Framework (DEF) allows (1) deploy central (2) integrate these at runtime user way The environment routine completely transparent chosen environment. DEF provides client APIs with primitives like...

Within the Austrian Grid project phase 2, three different groups, each allocated to a work package, join their efforts implement grid infrastructure for european research "Breath Gas Analysis molecular oriented diseases''. This position paper provides background on task and resulting requirements, presentation solutions developed during related projects in application domain, identifies problems that have not yet been solved, finally presents intended solution be developed.

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 is mainly consolidated two independently targeted frameworks: data life cycle management framework e-Science applications and code execution handling multiple problem solving environments. first based on our previous work, particular...

Sharing data within grid environments always results in losing control over usage. If the shared information is medical data, this violates laws as specified HIPAA, because access to such must be reconstructible and needs tightly controlled. To comply with these regulations it guaranteed, that each modification recorded produce audit trails. The provided solution introduces a new concept for virtual computing consisting of secure machines, hosting indemnifying thorough trails by logging...

Within the Mobility Choices (MC) project we have developed an app that allows users to record their travel behavior and encourages them try out new means of transportation may better fit preferences. Tracks explicitly released by are anonymized can be analyzed authorized institutions. For recorded tracks, freely available automatically determines segments with mode; analyzes track according criteria environment, health, costs, time; indicates alternative connections criteria, which...

In 2003, MIT Technology Review listed Grid computing as one of 'Ten Emerging Technologies That Will Change the World' [5]. Five years later, is ready for undergraduate classroom? this panel, a group educators share their experiences in teaching over past several and various settings, discuss how subject materials should be developed future. Key points under discussion include place curriculum, role programming exercises, bottom-up versus top-down approaches, necessary platform. This panel...

The life-science and health care research environments offer an abundance of new opportunities for improvement their efficiency productivity using big data in collaborative processes. A key component this development is e-Science analytics, which typically supported by Cloud computing nowadays. However, the state-of-the-art technology does not provide appropriate support high-productivity analytics. In paper, we show how Cloud-based analytics systems can be increased (a) supporting...

An application's user documentation, also referred to as the manual, is one of core elements required in application distribution. While there exist many tools aid an developer creating and maintaining documentation on for code itself, are no that complement development with modern graphical applications. Approaches like literate programming not applicable this scenario, a library, but full be documented end-user. Documentation generation applications up now was only partially feasible due...

Sharing data within Grid environments can potentially result in losing control over usage. If the shared information is medical laws must be followed, enabling tightly controlled, reconstructible access. To comply with these regulations it guaranteed, that each access and modification recorded to enable audit trails. The provided solution introduces a new concept for virtualized Data which consist of secure virtual machines, harnessing hosting indemnifying thorough trails by logging...
