Outline

• NEEScentral Overview
• Data Repository
• Telepresence
• Collaboration
• Future Plans

3
Overview NEES accounts

• NEES accounts give you access to
• NEEScentral data repository
• Telepresence capabilities
• Equipment Site NEESpops
• If you do not have an account, request one now
  at
• https//central.nees.org/acct
• Forget your password?
• https//central.nees.org/acct/forgotpass.php

4
Project Membership

• All project members may
• Create experiments, trials, and subfolders
• Upload data and other documentation
• Access (download/view) all parts of the project
• Admins may
• Delete subfolders and files
• Add members to a project
• NEESit Recommendation
• Make MUST-SIM and/or Project IT staff the project
  admin to start (and include a backup person)

5
Data Repository Interim File Hierarchy
6
Interim File Hierarchy (contd)

• Designed for flexibility
• Unlimited number of subfolders may be created
• A note on deletion
• ONLY allowed by the project admins
• Files may be uploaded individually or in bulk
• References
• http//it.nees.org/documentation/library/data_meta
  data/000281.php

7
From The Top Projects

• Each NEESR and preNEESR should have its own
  project
• Projects allow you to share data with other
  researchers
• All NEES users may create/manage their own
  project

8
Documentation Subfolders

• Exist at each level of the hierarchy
• NEESit Recommendation
• Place document(s) at the highest vertical level
  in the hierarchy where it is still relevant
  across the horizontal levels

9
Analysis Subfolders

• Pre-test simulations, design parameter studies,
  and post-test simulations
• Include all input and output files
• Document any assumptions made

?
10
Metadata

• Add metadata at the highest level
• Project/Experiment/Trial
• Subfolders
• Files
• Current metadata fields are very high level
• Title/Name
• Description
• Objective
• Start/End Date
• Add documents describing metadata when existing
  metadata fields are inadequate

11
Experiments

• Typically at least one (or more) experiment(s)
  per research group associated with the NEESR
• Experiment Setup
• Documents describing test setup, instrumentation
  plans, designs for specimen components, etc

12
Trials

• Minor changes to the configuration parameters
  defined at the experiment level
• Some experiments have only 1 trial
• Centrifuge tests typically have multiple trials
• Trial Configuration
• Files describing specific differences in the
  experiment setup that make this trial unique

13
Trial Repetitions

• Trials run multiple times without changes to
  setup/trial parameters
• Data averaged to improve data quality
• Trial repetitions store multiple data sets with
  no changes to setup/configuration

14
Trial Data

• Unprocessed Data
• Raw data files from data acquisition systems
  sensor data, video, still images
• Not always rawest form of data (or original
  source). Could be something converted or exported
  into another format
• Discourage use of proprietary formats in favor of
  exported formats
• Where you want to start sharing from (for
  deriving/converting)
• Up to PI to decide what is the most basic form of
  data
• Converted Data
• Data converted to engineering units and other
  simple conversations
• Example Voltage to strain/curvature/displacement,
  converting ASCII files from double float numbers
  to fixed decimal
• Corrected Data
• Data revised to compensate for problems or
  eliminate noise
• Include documentations describing modifications
  to the data
• Derived Data
• Secondary and tertiary data products
• Examples plotting rotation from displacement
  transducers, plotting strain profiles along a
  specimen axis

15
Data Sharing and Archiving Policy

• Policies apply to both experimental and
  simulation data
• Goals
• No data lost
• Ensure high quality data
• Provide sufficient data/metadata to reproduce
  experiment
• Investigators who create/collect data have a
  legitimate interest in benefiting from their
  investment of time and effort
• Data timelines
• Accessible to project participants as soon as it
  is recorded
• Structured Data submitted to the permanent
  repository within 6 months of the end of the
  experiment/simulation
• Made automatically accessible to the public no
  later than 12 months after the end of the
  experiment/simulation

16
Telepresence flexTPS

• Enables remote viewing and robotic control of
  live video over the internet
• Recommended tool for sharing video during an
  experiment
• Developed by Christopher Stanton, UT Austin

17
flexTPS (contd)

• Web browser is the only requirement
• Integrated with NEES authentication
  authorization
• Use your NEES account to access private streams
• Record capabilities available for authenticated
  users
• flexTPS User Guide

18
Data Viewing and Playback RDV

• Real-time Data Viewer
• View time synchronized, streaming data
• Live or archived
• Developed by Jason Hanley, SUNY/Buffalo
• Supported displays
• Numeric in chart or tabular form
• Video/Images in full resolution or scaled form
• Text Examples log messages, chat, etc

19
RDV (contd)

• Useful for remote collaboration during your
  experiments
• Requires use of Data Turbine
• See your IT admins or contact NEESit for details
  and/or assistance
• Obtain RDV from
• A NEESpop where you have access
• http//it.nees.org/support/demos/turbine/RDV.jnlp
• RDV Users Guide

NEES WebEx

• Real-time collaboration with distributed project
  team members
• Augment and complement face-to-face meetings with
  advanced online meeting capabilities
• Web-based, hosted service, with no up-front costs
  for new hardware or software
• Only requires a telephone and Internet connection
• Features
• View, annotate, or edit documents in real time
  through shared desktop or shared applications
• Shared white board
• Chat
• Video capabilities optional, but supports cheap
  web cameras
• Archive capabilities

• Future Work

22
NEEScentral

• Enhanced metadata model (ingestion tools)
• Google search
• PDFs, Word/Excel documents, etc
• Enhanced security
• Read only access to projects
• PI area
• Bulk Download
• Usability Enhancements
• File browsers, project and member sorting, etc

23
NEES Web Template

• Template for NEESR web sites
• Enables researchers to easily share data
• Page level security for project member access
• Linked to NEEScentral data repository, local data
  repository, or both
• Easily customizable
• Easily extensive by IT staff
• Interface to specific applications
• Provide customized tools that integrate with the
  data repository

24
SingleShot

• Christopher Stanton, UT Austin
• Supports NEESit interim hierarchy
• Extended metadata model
• Software Goals
• Enable researchers to manage data locally
• Synchronize with NEEScentral

25
NEES Activities Web Interface

• Web site to communicate current status of NEES
  research
• Publicly accessible for education and outreach
• Communicates dates and times for tests
• Highlights next four tests to occur
• Provides access to public telepresence
  streams/movies
