Fall 2020 Office Hours

Posted on by Aaron

[July 12, 2020] Fall 2020 office hours will be as follows:

Monday – 1-2 PM – 211 Cushing
Wednesday – 9-11 AM – CDT space in O’Shaughnessy
Friday – 8:15 – 11 AM – Dedicated appointment block in either Cushing / O’Shaughnessy (typically Cushing)

Friday mornings are a dedicated block for scheduled appointments with students (BACS, CSE) that are intentionally excluded from recurring meetings.  Simply shoot myself or one of the admins a note (Tiffanie Sammons if you are coming from the CSE side or Claire Shelly if you are BACS or interested in the BACS) at least the day before by COB (Close of Business) and you as a student can schedule an appointment.  Depending on where the appointments are best suited, I will hold them either in O’Shaughnessy or in Cushing.

The Monday and Wednesday times are open to walk-ins, no appointment needed.

WristSense / EuroViz

Posted on by Aaron

[March 30th, 2020] Two updates with regards to papers.  Our short paper for EuroViz 2020 entitled “Characterizing Exploratory Behaviors on a Personal Visualization Interface Using Interaction Logs” was accepted to appear.  Congrats to Poorna on her hard work in driving the paper through.

Our paper presented last week at WristSense 2020 entitled “Improved Sleep Detection Through the Fusion of Phone Agent and Wearable Data Streams” won Honorable Mention for the Apple Best Paper Award.  Congrats to Stephen on the presentation and Gonzalo on their work for the paper.

PASS Updates

Posted on by Aaron

[January 29th, 2020] A few interesting updates on what is going on with the work on PASS (Provider Accessible Storage Subsystem) which fits under the broader umbrella of our Redundancy Elimination at the Edge work that is funded by NSF.  A bit more under the hood work but hopefully some fairly neat work down below the break.

Off to Dublin in June for ICC 2020

Posted on by Aaron

[January 27, 2020] Will be off to Dublin, Ireland in June 2020 for ICC 2020 as our paper on using aggregation as an indication of available bandwidth via purely passive estimations was accepted to the CQRM symposium.  If I recall, it was roughly 20 years ago that I went to my first “big” conference attending ICC when it was in Helsinki, Finland.  One out of two papers in on this go round to ICC 2020.  Wicked cool paper by my former Ph. D student Dr. Lixing Song with an assist from my current Ph. D student Al-Amin Mohammed to get it over the finish line.  Bit more on the paper after the break.

WeHab Code Downloads

Posted on by Aaron

[January 26th, 2020] One item that comes up every once in a while is our old WeHab project which brought to bear low-cost peripherals for the purpose of helping out with stroke rehabilitation / balance impairment.  For those who are so inclined, you are welcome to download the executables of the code along with instructions via Google Drive.  Note that the executables come as is and may be a bit dated.

 

 

Journal Paper – A game-theoretic analysis on the economic viability of mobile content pre-staging

Posted on by Aaron

[January 23rd, 2020] Our journal paper entitled “A game-theoretic analysis on the economic viability of mobile content pre-staging” is now live via the Wireless Networks journal.  The paper focuses on mobile content pre-staging with an eye towards whether or not said pre-staging is solely beneficial to the provider or pre-staging gains are shared with the end-user.  This is related to our on-going work NSF grant focusing on PASS (Provider Accessible Storage Subsystem) as this was a pre-cursor paper to that effort that we published at the INFOCOM Workshop on Smart Data Pricing back in 2016.  This particular paper offers some nice new insights and an expanded analysis relative to the shorter workshop paper.  Kudos to Prof. Liao (my former student, now a tenured professor at Central Michigan) and Prof. Li for their fantastic work on this effort.

Two new publications @ WristSense

Posted on by Aaron

[January 16th, 2020] Very good news for my student Gonzalo Martinez and post-doc Steve Mattingly who had their papers accepted for WristSense 2020.

  • The first paper entitled “Improved Sleep Detection Through the Fusion of Phone Agent and Wearable Data Streams” focuses on the extent to which phone agent data, specifically the screen on / off state, impacts the accuracy of time to bed and wake time as observed by the wearable.
  • The second paper entitled “On the Quality of Real-world Wearable Data in a Longitudinal Study of Information Workers” explores the quality of wearable data in terms of data consistency, interruptions / missing data, and charging behavior from the Garmin vivoSmart 3.

Both of these efforts are drawn from our data for Tesserae with one presented by Gonzalo and the other presented by Steve at the WristSense workshop at IEEE PerCom this year. Congrats again to Gonzalo and Steve on a job well done in driving these papers!
