Summary Science gateways are digital interfaces to advanced technologies that support science/engineering research/education. Frequently implemented as Web and mobile applications, they provide access community resources such software, data, collaboration tools, instrumentation, high‐performance computing. We anticipate opportunities for growth within a fragmented community. Through large‐scale survey, we measured the extent characteristics of gateway (reliance on nature existing resources)...
Abstract nanoHUB.org is arguably one of the most successful science gateways funded by National Science Foundation (NSF). It cyberinfrastructure that supports Network for Computational Nanotechnology (NCN), currently serving over 240,000 users annually in 172 countries worldwide. features a range resources including seminars, online courses, short full-fledged tool-powered curricula, and 260 simulations modeling tools. nanoHUB functions as scientific cloud where cannot only design run their...
Nowadays, research in various disciplines is enhanced via computational methods, cutting-edge technologies and diverse resources including infrastructures instruments. Such are often complex researchers need means to conduct their an efficient way without getting distracted with information technology nuances. Science gateways address such demands offer user interfaces tailored a specific community. Creators of science face breadth topics manifold challenges, which necessitate close...
The Science Gateways Community Institute was one of the first two software institutes funded by National Foundation's Office Advanced Cyberinfrastructure in August, 2016. structure and services offered institute were developed as a result seven years planning grants that focus groups, 5000-person survey development strategic plan. Now in, we provide an overview institute's service offerings their usage, reflect on experiences some early clients, review our approaches to metrics evaluation,...
In this paper a heuristic decomposition algorithm for scheduling the generalized batch chemical plant is presented. The problem decomposed into smaller, more tractable problems which are solved to optimality. solutions smaller then concatenated in pre-specified manner get an approximate solution original problem. This consists mainly of two basic components: spatial and temporal decomposition. decomposition, represented as directed graph groups processing storage units. product orders...
With the rise of science gateway use in recent years, we anticipate there are additional opportunities for growth, but field is currently fragmented. We describe our efforts to measure extent and characteristics community through a large-scale survey. Our goal was understand what type support services might be provided community.
The science gateway nanoHUB.org is the world's largest nanotechnology user facility, serving 167, 196 users in 2010 with over 2,300 resources including 189 simulation programs. Surveys of nanoHUB and automated usage analysis find widespread use formal classroom education, thereby connecting recent research more rapidly closely to education. Analysis 719 citations scientific literature by 1,300 authors documents programs new collaborations, researchers outside community originating program,...
The science gateway nanoHUB.org, funded by the National Science Foundation (NSF), serves a large scientific community dedicated to research and education in nanotechnology with community-contributed simulation codes as well vast repository of other materials such recorded presentations, teaching materials, workshops courses. Nearly 330,000 users annually access over 4400 items content on nanoHUB, including 343 tools. Arguably largest facility world, nanoHUB has led way not only providing...
Workforce development is an important topic in distributed computing. While traditional curricula engineering and computer science focus primarily on disciplinary technical expertise, facilitating research cyberinfrastructures requires a diverse set of non-discipline-specific skills including usability, business planning, community building. Science gateways, digital platforms that facilitate the use complex computing resources, are increasingly popular form cyberinfrastructure. The Gateways...
Probabilistic mixture models have been widely used for different machine learning and pattern recognition tasks such as clustering, dimensionality reduction, classification. In this paper, we focus on trying to solve the most common challenges related supervised algorithms by using probability distribution functions. With modeling strategy, identify sub-labels generate synthetic data in order reach better classification accuracy. It means increasing training synthetically increase
The research landscape applying computational methods has become increasingly interdisciplinary and complex regarding the computing ecosystem with novel hardware, software, data, lab instruments.Reproducibility of results, usability tools, sharing are all crucial for timely collaboration teaching.HUBzero is a widely used science gateway framework designed to support online communities efficient publication processes.The paper discusses growth five gateways nanoHUB, MyGeoHub, QUBEShub,...
The main goal of the US Science Gateways Community Institute (SGCI) is to serve science gateways achieve sustainability and growth. allow engineering communities access shared data, software, computing services, instruments, educational materials, other resources specific their disciplines. Thus, are a subgroup scientific software means for addressing also suitable vice versa, e.g., best practices engineering. Since tailored communities, understanding users' requirements critical...
The science gateway framework HUBzero® has been enhanced and further developed since its initial vision in 1996 -- always driven by requirements of the diverse communities applying for their research. is part a computational landscape that never evolved as fast last decade. Novel frameworks concepts on user interface side such Javascript libraries Jupyter notebooks support working environment with easy-to-use interfaces while novel technologies backend allow effective efficient modeling,...
