PaN-data ODI Deliverable: D5.3 Abstract This report demonstrates and evaluates the services being developed within the PaN-data ODI project. A survey of the implementation status of these services at all participating institutes is in- cluded. The metadata catalogue plays a central role in the PaN-data project. Therefore it is dis- cussed how scientists benefit from this service. The status of the tomography database is re- viewed. Details of the NeXus deployment at various partners are presented. Eventually, three data processing frameworks, which are developed within the PaN-data community, are compared by implementing two scientific use cases.

  • Scientific Software Useful for the Undergraduate Physics Laboratory
    Scientific software useful for the Undergraduate Physics Laboratory Windows Microcal Origin Origin is quite well distributed within the scientific community and is used in some of the research groups in the Faculty of Physics and Geosciences in Leipzig. There is a license available for students. Origin 8 and 7.5 might be downloaded from http://research.uni-leipzig.de/zno/Software/ . This website is accessible from your computer at home via a VPN connection (see https://www.urz.uni-leipzig.de/hilfe/anleitungen-a-z/vpn/ ). Running Origin requires a connection to the license server; this is unproblematic, if you computer is logged in into the University network; from home, it should sufficient to run the VPN client on your computer. Alternatively, you might bring your notebook to the University, connect to the wireless, start Origin and borrow the license for a maximum of 150 days. Please note that the license is automatically returned the next time you open Origin, when connected to the University network. For other options see Mac and Linux. Mac IGOR This is software from Wavemetrics; IGOR runs also under Windows. License for students? No idea. For other options see Linux. Linux Qtiplot Qtiplot is free software (in principle) and quite similar to Origin. It runs under Linux, Windows and Mac. The official site is (http://soft.proindependent.com/qtiplot.html).

ISSN 0973-1768 Volume 11, Number 6 (2015), pp. 4937-4948 © Research India Publications http://www.ripublication.com A Review On The Comparative Roles Of Mathematical Softwares In Fostering Scientific And Mathematical Research Emetere Moses Eterigho1 and Sanni Eshorame Samuel2 1Physics Department, Covenant University, P.M.B. 1023, Ota, Nigeria 2Chemical Engineering Department, Covenant University, P.M.B. 1023, Ota, Nigeria [email protected] Abstract Mathematical software tools used in science, research and engineering have a developmental trend. Various subdivisions for mathematical software applications are available in the aforementioned areas but the research intent or problem under study, determines the choice of software required for mathematical analyses. Since these software applications have their limitations, the features present in one type are often augmented or complemented by revised versions of the original versions in order to increase their abilities to multi-task. For example, the dynamic mathematics software was designed with integrated advantages of different types of existing mathematics software as an improved version for understanding numerical related problems for advanced mathematical content (advanced simulation). In recent times, science institutions have adopted the use of computer codes in solving mathematics related problems. The treatment of complex numerical analysis with the aid of mathematical software is currently used in all branches of physical, biological and social sciences. However, the programming language for mathematics related software varies with their functionalities. Many invaluable researches have been compromised within the confines of unacceptable but expedient standards because of insufficient understanding of the valuable services the available variety of mathematical software could offer.
