Designing Your Ideal Creative Network.

Tuesday, September 25, 2012, 11:00am – 11:30am

Abstract

Difficult problems can often be solved by talking with the 'right' person. But, finding that person can be tricky. Social networking systems might make this easier, but they aren't really designed for problem solving. This talk will explore some of the ways in which we might develop networks that can amplify our problem solving skills.

Some Assembly Required: Organizing in the 21st century

Monday, September 24, 2012, 9:00am – 9:30am

Abstract

Recent technological advances provide comprehensive digital traces of social actions, interactions, and transactions. These data provide an unprecedented exploratorium to model the socio-technical motivations for creating, maintaining, dissolving, and reconstituting into teams – for research, business, or social causes. Using examples from research in virtual organizations (such as nanoHUB) and massively multiplayer online games, Contractor will argue that Network Science serves as the foundation for the development of social network theories and methods to help advance our ability to understand the emergence of effective teams. More importantly, he will argue that these insights will also enable effective teams by building a new generation of recommender systems that leverage our research insights on the socio-technical motivations for creating ties.

Ewa Deelman

Ewa Deelman is a Research Associate Professor at the USC Computer Science Department and a Project Leader at the USC Information Sciences Institute. Dr. Deelman's research interests include the design and exploration of collaborative, distributed scientific environments, with particular emphasis on workflow management as well as the management of large amounts of data and metadata. At ISI, Dr. Deelman is leading the Pegasus project, which designs and implements workflow mapping techniques for large-scale applications running in distributed environments. Pegasus is being used today in a number of scientific disciplines, enabling researches to formulate complex computations in a declarative way. Over the years, Dr. Deelman worked with a number of application domains including astronomy, bioinformatics, earthquake science, gravitational-wave physics, and others. As part of these collaborations, new advances in computer science and in the domain sciences were made. For example, the data intensive workflows in LIGO (gravitational-wave physics) motivated new workflow analysis algorithms that minimize workflow data footprint during execution. On the other hand, improvements in the scalability of workflows enabled SCEC scientists (earthquake science) to develop new physics-based seismic hazard maps of Southern California. In 2007, Dr. Deelman edited a book on workflow research: “Workflows in e-Science: Scientific Workflows for Grids”, published by Springer 2007. She is also the founder of the annual Workshop on Workflows in Support of Large-Scale Science, which is held in conjunction with the Super Computing conference. In 1997 Dr. Deelman received her PhD in Computer Science from the Rensselaer Polytechnic Institute. Her thesis topic was in the area of parallel discrete event simulation, where she applied parallel programming techniques to the simulation of the spread of Lyme disease in nature.

Managing Workflows Within HUBzero: How to Use Pegasus to Execute Computational Pipelines

Monday, September 24, 2012, 11:30am – 12:00pm

Abstract

This talk will focus on the ability to construct and execute computational pipelines/workflows within the HUBzero environment using the Pegasus Workflow Management System. Pegasus is available today in NEES.org, DiaGrid.org, and other hubs. Pegasus allows users to develop workflows at a high-level of abstraction, without worrying about the details of the execution environment. The workflow includes information about the workflow steps, the input and output data they take-in and produce. Each hub is pre-configured for a particular execution environment, so that users can seamlessly launch their workflows on the available resources. Pegasus provides monitoring interfaces to follow the progress of the workflow. When failures occur, it tries to recover from them. However, if recovery is not possible, Pegasus provides detailed failure information. The standalone version of Pegasus has been used in a variety of domains: astronomy, bioinformatics, earth science, physics, and others. Pegasus within the hub opens up its capabilities to a broader range of users.

The Science Gateways and their Democratization and Acceleration of Science

Tuesday, September 25, 2012, 9:30am – 10:00am

Abstract

As science today grows increasingly digital, it poses exciting challenges and opportunities for researchers. Whether it¹s streaming data from sensors, simulating the formation of tornadoes, annotating and sharing tagged audio and video data, or using geographic information systems to anticipate the spread of disease, the frontiers of transformative science are enormous and continue to grow. Many scientists are turning to web portals or science gateways to allow them to analyze, share, and understand large volumes of data more effectively. The existence of science gateways ‹ and the sophisticated cyberinfrastructure (CI) tools and resources behind these accessible web interfaces can significantly improve the productivity of researchers facing the most difficult challenges. Most important, science gateways can democratize access to the cyberinfrastructure that enables cutting edge science. Now the best minds can tackle today¹s most challenging science problems, regardless of institutional affiliation.

Science gateway developers face several challenges. They often work in isolation even though development can be quite similar across domain areas, they bridge local, campus, national and sometimes international cyberinfrastructure, they need foundational building blocks so they can focus on higher-level grand-challenge functionality. Sustainable funding for science gateways can also be difficult to secure as they span the worlds of research and infrastructure. Experiences from the 7-year TeraGrid Science Gateways program, continuing gateway activities in XSEDE and new efforts to form a Science Gateways Institute will be discussed.

Welcome and describe the format of the Science Gateways breakout session

STEMEdhub.org a Group Approach to Hubs

Tuesday, September 25, 2012

Abstract

Authors: Ann Bessenbacher, Debora Steffen, Gabriela Weaver, Wilella Burgess

Unlike most hubs that are designed around one central concept, STEMEdhub.org was created under the general concept of STEM (Science, Technology, Engineering and Math) Education and it was designed as a set of smaller hubs set up as groups. We envisioned communities of practice being created under these smaller group umbrellas in the beginning, but as the hub evolves and grows over time we see the communities blending with each other and new larger communities emerging. The group approach has also allowed us to maximize the benefits of having a hub to many projects while sharing the expense of creation and maintenance amongst them. It also provides a robust and sustainable base that will continue beyond the life of any one project.

At the moment STEMEdhub.org has groups under three central themes: K-12 education, undergraduate education, and STEM education conferences. While developing groups in these areas we have discovered best practices, as well as how to maximize group features. During the presentation I will show how we have set-up the hub amongst the different groups, the best practices we have learned, new resource organization developed for groups, the challenges of working with multiple groups and agendas, as well as ideas for future group developments.

Porting HUBzero to RHEL6

Tuesday, September 25, 2012, 4:00pm – 4:30pm

Abstract

In this presentation we discuss our effort in porting the HUBzero platform from Debian GNU/Linux 5.0 "lenny" to Redhat Enterprise Linux 6.0, RHEL6. RHEL6 is the most commonly utilized enterprise-class Linux distribution, and is required by our University's data center to integrate with existing services for virtual machine management, firewall management, data backup management, system monitoring, and security updates. We have taken the open source HUBzero packages, available from hubzero.org, and repackaged them from Debian's .deb format to RHEL6's .rpm package format. Building RPM packages not only includes the required software and data files, but also post-installation scripts to properly configure the software in an RHEL6 environment and setting a YUM repository for hosting our RPM packages. During the talk, we will cover the issues involved in porting the HUBzero platform to different versions of OpenLDAP, MySQL, Apache, and OpenVZ than it was originally designed for. Finally, we will present a GitHub hosted repository of our RPM build scripts, so that other HUBzero users may easily contribute changes.

ISO:16363 & OAI-PMH: Research Data Management in the HUBzero Environment

Monday, September 24, 2012

Abstract

Authors: Amy Hatfield, Neal Harmeyer, Matthew Kroll, Brandon Beatty

The Purdue University Research Repository (PURR), built on the HUBzero platform, is designed to provide a virtual collaboration space for scientific research with the support of long-term preservation strategies. In light of the National Science Foundation Data Archiving Policy which states “researchers have a special obligation to scientific openness and accountability when the research is publicly funded," PURR serves as both research environment and data management provider. As PURR users may submit research data in a variety of file formats, a number of steps must be taken to successfully maintain data functionality. In order to insure long-term preservation and accessibility of the data, preservation actions take place at submission and throughout the life of each dataset. At present, HUBzero does not include robust long-term preservation support; as such, the PURR Project Team has been working to extend the PURR HUBzero platform to that end. The primary guiding document in this process has been the ISO:16363 Standard for Trustworthy Digital Repositories. The ISO standard calls for the implementation of descriptive and preservation metadata models, digital preservation planning and procedures, and a commitment to repository security and longevity. Additionally, the project team has focused upon integration of the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). During a panel presentation, the PURR Project Team will illustrate and discuss the methods being employed to extend the HUBzero platform to comply with the NSF Data Archiving Policy and ISO:16363 Trusted Digital Repositories Standard.

Introducing the Rappture Toolkit

Monday, September 24, 2012

Abstract

Rappture is the Rapid APPlication infrastrucTURE, a toolkit within the HUBzero platform that makes it easy to develop a graphical user interface for scientific modeling tools. Once you describe the input/output for your simulator, Rappture handles the rest, generating a graphical interface automatically based on your description. Within your code, you access the input values and save resulting output values by using the Rappture application programming interface, which has bindings for a variety of languages, including C/C++, Fortran, MATLAB, Octave, Python, Perl, Java, Ruby, and Tcl. You can embed the Rappture calls within your tool, or create a wrapper script that wraps around your tool, leaving it untouched. Either way, users will see a simple, graphical interface where they can enter input values, press the "Simulate" button, and visualize the outputs as line graphs, contour plots, 3D isosurfaces, molecules, and more. They can run your tool again and again, and explore your model within a large parameter space. The resulting application is easy to deploy on any HUBzero-powered site, so a large community of users can access it through their web browser.

This talk provides an overview of Rappture and shows how to create tools in minutes by using the new Rappture builder.

What is under the hood?

Uploading and publishing new tools

Tuesday, September 25, 2012

Abstract

HUBzero lets you access simulation tools online via an ordinary web browser. Where do the tools come from? From you--hundreds of you throughout the world who are developing simulation and modeling tools for your hub. Anyone can upload their own code onto a hub and publish a tool for a limited group of colleagues or for the entire world to use. The code can be kept protected or given out as open source.

This tutorial shows you exactly how to do that, starting with the tool registration form, taking you through the process of uploading code into a Subversion repository, developing and testing your code within a workspace, and finally, approving and publishing your tool. This is a good starting point for all new tool developers, to help them understand the overall process.

Tuesday, September 25, 2012

Abstract

Rappture is the Rapid APPlication infrastrucTURE, a toolkit within the HUBzero platform that makes it easy to develop a graphical user interface for scientific modeling tools.

This talk describes the new Rappture Regression Tester tool, which executes a series of tests that you define to verify the correct operation of your tool. Use this tool as you fix bugs and introduce new features, to make sure that your tool continues to function correctly in all cases. Where discrepancies are found, this tool will flag the differences and help you understand whether your tool is broken or the new behavior is correct.

Using cceHub components to build simple data exploration tools

Monday, September 24, 2012

Abstract

Several components developed as part of the cceHUB database project (namely com_dataview and com_form) were used to PROTOTYPE a new component supporting basic data exploration functions: the creation and display of frequency charts/tables, cross-tabulations, simple regressions, and correlation matrices.

These functions access individual tables already uploaded to databases accessible from the Hub; there is no provision at this time for uploading data that can then be explored, although tools for doing so have also been built using com_form, and could in principle serve that function.

This presentation would hope to identify interest among conference attendees to justify further development of the PROTOTYPE, since this software is not ready for deployment at this time.

Usability Evaluation of a Research Repository and Collaboration Website for Human-Animal Bond Researchers

Tuesday, September 25, 2012

Abstract

Authors: Tao Zhang, Deborah J. Maron, Christopher C. Charles

This paper describes an empirical usability evaluation of HABRI (Human-Animal Bond Research Initiative) Central as part of the effort to develop an open-access research repository and collaboration platform for human-animal bond researchers. By repurposing and altering key features of the original HUBzero system, HABRI Central hosts previously published materials from related disciplines and an extensive bibliography, in addition to traditional hub materials such as tools and datasets. It is expected that changes made in HABRI Central can be extended to other hubs with similar bibliographic functionality requirements.

Seven graduate students in the College of Veterinary Medicine at Purdue participated in the usability evaluation. They performed tasks including exploration of the system, finding an article in the repository, submitting an article to the repository, adding bibliographic information of an article to the repository, and using user groups and questions and answers. Participants also answered open questions regarding their overall experience and rated HABRI Central’s usability using the System Usability Scale (SUS). Response measures included task successfulness, navigational steps, task time, participant comments and behavior notes recorded by the experimenter. The evaluation took about one hour for each participant.

Results of the evaluation showed that the overall user experience of HABRI Central is satisfactory, but the results also indicated a number of usability issues. Participants had difficulty in inputting metadata such as resource type and author information when submitting an article to the repository. Participant comments and experimenter notes during the article submission process indicated that the workflow could be further improved to reduce user confusion. There were also interface design issues regarding page layout and consistency. It is expected that findings from this study and the evaluation methodology can be extended to the development and evaluation of similar systems based on the HUBzero platform.

PURR: A Research Data Curation Service Model Using HUBzero

Monday, September 24, 2012

Abstract

Authors: Courtney Earl Matthews, Michael Witt

The Purdue University Research Repository (PURR, http://research.hub.purdue.edu) uses HUBzero to provide a research collaboration and data management solution for campus researchers. The National Science Foundation, the National Institutes of Health, and other funding agencies have begun requiring that researchers describe in their grant proposals how they will manage and share the data that will be produced in their research. Purdue researchers can include PURR in their data management plans, invite collaborators to work with them in private projects on PURR, and publish datasets that can be cited using Digital Object Identifiers (DOI). This presentation will explore Purdue’s data repository service model including its service definition, governance, roles and responsibilities, workflows, policies, and support, in addition to the functional role of HUBzero. The collaborative approach of the Purdue University Libraries, Office of the Vice President for Research, and Information Technology at Purdue in developing and maintaining PURR will also be presented. Support for the entire research data lifecycle – from the creation of datasets to their long-term digital preservation and eventual reuse – will be displayed in a live demonstration that will include an overview of the project functionality and dataset publication that was developed for PURR.

WaterHUB: Enabling hydrological exploration, modeling and collaboration

Tuesday, September 25, 2012

Abstract

Authors: Lan Zhao, Carol X. Song, Venkatesh Merwade, Shandian Zhe

Studies of water in the environment are fundamental in many research disciplines. The importance of understanding water related issues, including quantity and quality at local, national, and global sales, has grown significantly in the past decade. There is a strong need for a community-oriented cyberinfrastructure for researchers and educators to explore hydrological processes using observed data and computationally intensive modeling tools. For example, the SWAT model (Soil and Water Assessment Tool) has been widely used to study the impact of land management practices in large, complex watersheds. The model is data intensive and requires a lot of computation power, for example, to calibrate for a large watershed. However, researchers typically run this model as a stand-alone desktop application, which not only limits the size of the problems that researchers can tackle due to resource constraints, but is not conducive to collaboration. No service exists that allows modelers to share their model inputs which are time-consuming to set up. This presentation will describe the development of a hydrological collaboration tool and workflow, SWATShare, in the WaterHUB (http://water-hub.org). SWATShare not only supports end-to-end SWAT simulations using the XSEDE HPC resources but also allows easy data/model publishing, discovery and sharing within the community. The SWATShare tool builds on top of the HUBzero web platform and is implemented using an extensible layered system architecture including a FLEX based GIS user interface, a set of geospatial data and modeling services, and HPC resources at the backend. It extends the core HUBzero software stacks to bring large scale geospatial data and modeling capabilities into HUBzero. We will also discuss our experience of using SWATShare in a civil engineering graduate-level class taught at Purdue in fall 2011 as well as future work. Our experience developing the WaterHUB will also contribute to a recently awarded NSF SI2 project.

Using the work-flow management functionality in the PharmaHUB

Tuesday, September 25, 2012

Abstract

Authors: L. Mockus, G. Joglekar, J.M. Laínez, G.V. Reklaitis

The pharmaHUB (www.pharmahub.org) was created for research collaboration and knowledge sharing in the pharmaceutical domain. The pharmaHUB is implemented on the HUBzero2 platform whose main features include the capability of performing interactive simulation and modeling tools via a web browser. Currently, the pharmaHUB encompasses a range of contributed models and simulations, including particle-surface adhesion, DEM modeling of rotating drums, hopper discharge and high shear mixing, compartment modeling of particle blending, roller compaction, cake filtration, tablet dissolution, visualization of molecular crystals and multipurpose plant production planning among others. These tools address different portions of the product development cycle and are deployed independently. However, it is usually required along the product development cycle to have the outputs of some of these tools as partial inputs for another one. Here, we describe the use of one of the latest Hub capabilities which allows connecting different independent simulation tools using a Pegasus workflow management model. Two examples are provided. One of them is related to the process of individualizing drug dosage regimens using two tools: a Bayesian parameter estimator for the drug gabapentin and a dose optimizer. The second example is an interactive data entry and retrieval system for managing the information generated during dry powder blending experiments. The key component of the system is the workflow for the associated experiment. The workflow allows capturing the operational aspect of a work procedure. It also provides the reference points for defining the data to be recorded and designing the data entry forms. Each recorded experiment is an instance of its associated workflow. The experimental data is stored in a MySQL database and can be retrieved using a graphical user interface.

CyberSecurity for NEEShub: Best-practices and Lessons Learned

Tuesday, September 25, 2012, 4:30pm – 5:00pm

Abstract

The George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) operates a shared network of civil engineering experimental facilities aimed at facilitating research on mitigating the impact of earthquakes. The network depends on a reliable distributed cyberinfrastructure among 15 universities to successfully work as an integrated co-laboratory for over 5,000 users from around the world.

Cybersecurity is a critical aspect to achieve the reliability required for research environments such as NEES. The network has developed a comprehensive cybersecurity approach that includes best-practice cybersecurity policies and controls and annual security audits at each of the NEES sites. The goal of the cybersecurity practices is to protect the computational resources and archived research data at NEES from malicious access that might violate the data’s confidentiality or integrity or make the network or its data unavailable. Eight types of security controls have been implemented: user authentication; access control; perimeter defenses; network engineering; monitoring/auditing; data loss prevention; security evaluations; and patch management.

In this talk, we will review the evolution of the NEES cybersecurity infrastructure since its inception at Purdue University and will present a description of the security controls implemented to fulfill the particular requirements of this projects. Finally, we will share experiences and lessons learned from a handful of actual cybersecurity incidents.

Implementation of HUBzero as a Knowledge Management System in a Large Organization

Monday, September 24, 2012

Abstract

Authors: Gaurav Nanda, Jonathan Tan, Peter Auyeung, Mark Lehto

HUBzero has not only been an effective research and academic collaboration platform but through this study, it has also proven itself to be an effective knowledge management solution for commercial organizations. Knowledge management efforts typically focus on organizational objectives such as improved performance, competitive advantage, innovation, the sharing of lessons learned, integration and continuous improvement of the organization. In an ongoing project with Reliability Engineering division of a large company, the HUB-in-a-box version of HUBzero has been successfully implemented to play the role of a knowledge base of different reliability tools being used in the company like Failure Mode Effects Analysis, Reliability Growth Curves etc. HUBzero acted as a medium for building organizational memory and will allow people in working different areas to collaborate in a social networking manner which will not only improve the quality of the work but will also save a lot of time by reusing the work done by colleagues to solve a similar problem.

Challenges faced during the implementation of HUBzero included selection of the HUBzero server and maintaining its security, which were accomplished with the help for HUBzero development team at Purdue. We also devised a method for automated data collection from people and getting author's consent before publishing. A dashboard was developed by interfacing HUBzero and one of the existing groupware in the organization for selecting and publishing good quality resources.

Some of the areas in which ongoing/future work is planned include developing a generic guideline/template for requirements analysis for HUBzero implementation projects. We also want to develop the measures of effectiveness, metrics detailing how much HUBzero actually helps the end users by performing usability analysis. Based on the results of these studies, we expect to enhance the usability of HUBzero as a knowledge management system in a large enterprise setting.

Data Curation and Quality Assurance in NEEShub

Monday, September 24, 2012

Abstract

Earthquake engineering is a vibrant inter-disciplinary area that brings together researchers from seismology, structural, mechanical, and geotechnical engineering whose effort results in saving lives and protecting property during earthquakes and tsunamis. The NEES Data Repository serves the needs of the earthquake engineering community. Research teams carry out path-breaking research on small and large scale models using among other equipment shake tables, tsunami basins, and centrifuges. Such diversity represents a challenge for the collection of data and of sufficient documentation to make the data and the conditions of their origin understandable, not only to the earthquake research community, but also to practitioners and educators in the present and in the future.

Data use and re-use is one of the key goals of the NEES, during this talk I will discuss some of the solutions implemented by the NEEScomm IT team in the NEEShub that help to manage research data, collect necessary metadata and documentation for correct understanding and interpretation of the archived data. The high-quality of metadata, their consistency and predictability is essential for successful stewardship of research data and for easy transfer of knowledge from the research team to the repository with as little loss as possible. The tools that assist research teams with archiving their data need to be intuitive and non-intrusive so that the processes of metadata capture and solicitation of documentation can be pushed upstream back to the research teams that are the best source information. The NEES preservation framework is a blend of system provided data, information extracted from the files themselves, and metadata solicited from the research teams. It is an environment that provides storage for long-term access to authentic re-usable research data and preservation services, as well as virtual space for sharing and collaboration.

Upper Cumberland Rural STEM Initiative

Tuesday, September 25, 2012

Abstract

Authors: Sally Pardue, Marc Robinson

The Upper Cumberland Rural STEM Initiative through the Millard Oakley STEM Center at Tennessee Technological University is using HUBzero to power an online collaboration zone designed to bring together three key partner types to enhance science, technology, engineering, and mathematics education. Twenty-one local education agencies (LEAs) covering more than 6000 square miles and serving more than 72,000 students, eleven community and business entities, and three post-secondary institutions form the UCRSI. This regional project serves a economically challenged rural area and is part of the TN STEM Innovation Network (theTSIN.org), a funded program under Tennessee's Race To the Top grant from the federal Department of Education. HUBzero allows the UCRSI project to reduce start-up costs and to decrease time to implementation by not requiring a "design and build from scratch" approach to communication. We are able to jumpstart a welcoming interactive web portal where members can immediately retrieve useful information and form working groups to share STEM education resources across the boundaries of k-12 education, higher education, and industry. UCRSI.org hosts open groups formed by the membership of teachers, community volunteers, and families as well as restricted groups for related professional development workshops for STEM education. The presentation will provide a timeline for live site implementation and strategies for membership growth and engagement.

Windows Tools on NEEShub

Tuesday, September 25, 2012, 2:00pm – 2:30pm

Abstract

Authors: Brian Rohler, Rajesh Thyagarajan, Dawn Weisman

The signature service of a hub is its ability to deliver interactive, graphical simulation tools through any web browser. In the world of portals and cyber-environments, this capability is unique. Unlike a portal, tools in a hub are interactive; actions can be performed, without waiting for a web page to refresh. Results can be visualized without having to obtain a login to a supercomputer, reserve time on a supercomputer, or wait for a batch job to engage. New tools can be deployed without writing special code for the web.

The Network for Earthquake Engineering Simulation (NEES) infrastructure is made up of 14 earthquake engineering and tsunami research sites located at universities across the United States. NEEShub (http://nees.org) connects the work of the research sites’ experimental facilities, researchers, practitioners, educators, and students. NEEShub acts as the gateway to the earthquake engineering research data repositories and to a virtual research environment.

NEEShub is powered by the Hubzero infrastructure and hence includes a tool execution and delivery mechanism based on Virtual Network Computing (VNC). Using this architecture, NEEShub has over 50 different tools, out of which 11 are Windows based, with more tools under development. NEEShub relies on its user community to contribute tools and other resources. Participation from the community is important as this helps NEEScomm provide a more sophisticated set of useful tools to the NEES community.

NEEShub is the first and currently, the only hub that provides Windows based tools to the NEES community. This presentation will present greater insight into the tools that are available on the NEEShub, demonstrate the complete Windows tool contribution workflow and offer insight into the implementation details including the system architecture, software and hardware requirements.

InvertNet: Advancing Digitization of Biological Collections

Tuesday, September 25, 2012

Abstract

Authors: Omar Sobh, Joe Leigh, Obaid Sarvana, Nahil Sobh

InvertNet, one of the three Thematic Collection Networks (TCNs) funded in the first round of the U.S. National Science Foundation’s Advancing Digitization of Biological Collections (ADBC) program, is tasked with providing digital access to ~60 million specimens housed in 22 arthropod (primarily insect) collections at institutions distributed throughout the upper midwestern USA. The traditional workflow for insect collection digitization involves manually keying information from specimen labels into a database and attaching a unique identifier label to each specimen. This remains the dominant paradigm, despite some recent attempts to automate various steps in the process using more advanced technologies. InvertNet aims to develop improved semi-automated, high-throughput workflows for digitizing and providing access to invertebrate collections that balance the need for speed and cost-effectiveness with long-term preservation of specimens and accuracy of data capture. The proposed workflows build on recent methods for digitizing and providing access to high-quality images of multiple specimens (e.g., entire drawers of pinned insects) simultaneously. Limitations of previous approaches are discussed and possible solutions are proposed that incorporate advanced imaging and 3-D reconstruction technologies. InvertNet couples efficient digitization workflows with a highly robust network infrastructure capable of managing massive amounts of image data and related metadata and delivering high-quality images, including interactive 3-D reconstructions in real time via the Internet.

The Balancing Act of Release Management

Tuesday, September 25, 2012, 11:30am – Noon

Abstract

The Wish list is the mechanism many Hubs use to collect requests for new or enhanced functionality. A large Wish list is a classic ‘good problem’ indicating an active user community with creative ideas for improving a Hub.

Since most IT teams are limited in the number of people available to implement wishes, numerous decisions need to be made regarding how to work through wishes in the Wish list or, for more complex Hubs, how to bundle a set of wishes into a software release. Variables such as strategic direction, available resources, user expectations, yearly timing, and wish complexity/duration must all be taken into account.

NEEScomm IT, the team responsible for NEEShub, has been managing a large, diverse Wish list since July 2010. Working with key users in the NEES community, an overall release process has been developed and followed to review, prioritize, and select wishes for each release cycle. This talk will describe the basic steps in the NEES release process and lessons learned from multiple iterations through the process.

Usability Evaluation of a Research Repository and Collaboration Website for Human-Animal Bond Researchers

Tuesday, September 25, 2012

Abstract

Authors: Tao Zhang, Deborah J. Maron, Christopher C. Charles

This paper describes an empirical usability evaluation of HABRI (Human-Animal Bond Research Initiative) Central as part of the effort to develop an open-access research repository and collaboration platform for human-animal bond researchers. By repurposing and altering key features of the original HUBzero system, HABRI Central hosts previously published materials from related disciplines and an extensive bibliography, in addition to traditional hub materials such as tools and datasets. It is expected that changes made in HABRI Central can be extended to other hubs with similar bibliographic functionality requirements.

Seven graduate students in the College of Veterinary Medicine at Purdue participated in the usability evaluation. They performed tasks including exploration of the system, finding an article in the repository, submitting an article to the repository, adding bibliographic information of an article to the repository, and using user groups and questions and answers. Participants also answered open questions regarding their overall experience and rated HABRI Central’s usability using the System Usability Scale (SUS). Response measures included task successfulness, navigational steps, task time, participant comments and behavior notes recorded by the experimenter. The evaluation took about one hour for each participant.

Results of the evaluation showed that the overall user experience of HABRI Central is satisfactory, but the results also indicated a number of usability issues. Participants had difficulty in inputting metadata such as resource type and author information when submitting an article to the repository. Participant comments and experimenter notes during the article submission process indicated that the workflow could be further improved to reduce user confusion. There were also interface design issues regarding page layout and consistency. It is expected that findings from this study and the evaluation methodology can be extended to the development and evaluation of similar systems based on the HUBzero platform.

Abstract

Authors: H. Zhong, J.D. Velasquez, G. Nanda, E. Huebner

Collaboration is one of the key outcomes of Senior Design (SD), a course common to many engineering schools, aiming to encourage students to work in teams, analyze and synthesize unstructured problems in practical settings, and help prepare students for the workplace. SD students face challenges with locating, synthesizing, and integrating the distributed knowledge and expertise in an effort to address the real-world problem given to them as part of the course. Due to the overload of information, the innovation and decision-making expected of the students can sometimes be slow, erratic and disjointed. To enhance the collaboration of SD students, HUB-CI, which is being developed by faculty members and students of the School of Industrial Engineering at Purdue University Collaboratorium Initiative, enhances HUB capabilities with collaborative intelligence (CI). Collaborative Control Theory (CCT) methodologies and tools have been designed to optimize the utility of various networks on HUB-CI. In the portfolio of HUB-CI, Collaborative Network Optimization (CNO) matches resources to related collaborative participants by minimizing the total cost of mapping. Based on CNO, the tool CNO Team Formation can automatically provide dynamic matching and grouping of students to appropriate projects according to students’ skills, area of interest, and customer expectations. Another methodology in HUB-CI, Collaborative Insight (Co-Insight), is the core of collaboration tools such as Co-viz and Co-design. It facilitates collaboration by reducing conflicts and errors while participants are working asynchronously in parallel. Co-viz keeps the collaborative decision-making smoother by providing analytics results and visualizations automatically, and Co-design enables remote physical collaboration in the lifecycle of engineering development through telerobotics testbeds. Several existing and emerging HUB-CI protocols and tools designed in the domain of education and engineering are also being applied for cultural, art, business, and healthcare networks. Preliminary results from the implementation of HUB-CI in a SD course will be presented.
