A Web Based Approach to Virtual Appliance Creation, Programming and Management
The Internet and Web technology is advancing at a frantic pace, expanding into almost every aspect of our everyday life. One of the latest scientific activities for the Internet and the Web is the so-called pervasive or ubiquitous computing where networking plays a vital role in its core computational framework. In this, people are able to use the Internet and Web to manage the operation of embedded network devices, services and to coordinate their services in ways that create applications such as smart-homes, smart-offices, smart-cars etc, collectively referred to as intelligent environments. For ordinary people (non technologists) to be able to use this technology, it is required that the interaction between the users and the environment must be as transparent and simple as possible, employing intuitive and user-friendly interfaces wherever possible. A popular approach to empowering users to customise the functionality of their environments is via end-user programming. In this work-in-progress paper we describe an approach based on using a web based GUI to augment earlier work of ours concerning an end user programming paradigm known as Pervasive interactive Programming (PiP), in a way that makes it more flexible and easy to use. By doing this, we present a conceptual model and discuss the issues in developing and using this model. © 2010 IEEE
High-Performance Cloud Computing: A View of Scientific Applications
Scientific computing often requires the availability of a massive number of
computers for performing large scale experiments. Traditionally, these needs
have been addressed by using high-performance computing solutions and installed
facilities such as clusters and super computers, which are difficult to setup,
maintain, and operate. Cloud computing provides scientists with a completely
new model of utilizing the computing infrastructure. Compute resources, storage
resources, as well as applications, can be dynamically provisioned (and
integrated within the existing infrastructure) on a pay per use basis. These
resources can be released when they are no more needed. Such services are often
offered within the context of a Service Level Agreement (SLA), which ensure the
desired Quality of Service (QoS). Aneka, an enterprise Cloud computing
solution, harnesses the power of compute resources by relying on private and
public Clouds and delivers to users the desired QoS. Its flexible and service
based infrastructure supports multiple programming paradigms that make Aneka
address a variety of different scenarios: from finance applications to
computational science. As examples of scientific computing in the Cloud, we
present a preliminary case study on using Aneka for the classification of gene
expression data and the execution of fMRI brain imaging workflow.Comment: 13 pages, 9 figures, conference pape

FABRIC: A National-Scale Programmable Experimental Network Infrastructure
FABRIC is a unique national research infrastructure to enable cutting-edge and exploratory research at-scale in networking, cybersecurity, distributed computing and storage systems, machine learning, and science applications. It is an everywhere-programmable nationwide instrument comprised of novel extensible network elements equipped with large amounts of compute and storage, interconnected by high speed, dedicated optical links. It will connect a number of specialized testbeds for cloud research (NSF Cloud testbeds CloudLab and Chameleon), for research beyond 5G technologies (Platforms for Advanced Wireless Research or PAWR), as well as production high-performance computing facilities and science instruments to create a rich fabric for a wide variety of experimental activities
Research and Development Workstation Environment: the new class of Current Research Information Systems
Against the backdrop of the development of modern technologies in the field
of scientific research the new class of Current Research Information Systems
(CRIS) and related intelligent information technologies has arisen. It was
called - Research and Development Workstation Environment (RDWE) - the
comprehensive problem-oriented information systems for scientific research and
development lifecycle support. The given paper describes design and development
fundamentals of the RDWE class systems. The RDWE class system's generalized
information model is represented in the article as a three-tuple composite web
service that include: a set of atomic web services, each of them can be
designed and developed as a microservice or a desktop application, that allows
them to be used as an independent software separately; a set of functions, the
functional filling-up of the Research and Development Workstation Environment;
a subset of atomic web services that are required to implement function of
composite web service. In accordance with the fundamental information model of
the RDWE class the system for supporting research in the field of ontology
engineering - the automated building of applied ontology in an arbitrary domain
area, scientific and technical creativity - the automated preparation of
application documents for patenting inventions in Ukraine was developed. It was
called - Personal Research Information System. A distinctive feature of such
systems is the possibility of their problematic orientation to various types of
scientific activities by combining on a variety of functional services and
adding new ones within the cloud integrated environment. The main results of
our work are focused on enhancing the effectiveness of the scientist's research
and development lifecycle in the arbitrary domain area.Comment: In English, 13 pages, 1 figure, 1 table, added references in Russian.

DEVELOPMENT AND IMPLEMENTATION OF A BIOINFORMATICS ONLINE DISTANCE EDUCATION LEARNING TOOL FOR AFRICA
Bioinformatics refers to the creation and advancement of algorithms, computational and statistical techniques and theories for solving formal and practical problems arising from the management and analysis of biological data. However, some parts of the African continent have not been
properly sensitized to bio-scientific and computing field. Thus, there is the need for appropriate strategies of introducing the basic components of this emerging scientific field to part of the African populace through the development of an online distance education learning tool. This study involved the design of a bioinformatics online distance educative tool an implementation of the
bioinformatics online distance educative tool by a programming approach. Design and implementation were done using the Borland Delphi 7 Enterprise edition within its Integrated Development Environment. The advantage of using Delphi programming language in implementing this useful bioinformatics web tool is that Delphi programming language is an object oriented programming language that has a lot of extra facilities for the enhancement of further technical
functions, which ordinary HTML cannot handle. The development and use of a bioinformatics distance education software, as a teaching tool, in some African countries holds great promise for accommodating the needs of the populace, who live in cities, small towns and remote areas
