Qualtrics has many features for skipping over questions that are not applicable to a particular respondent, and other more complex modes of branching. This workshop covers skip logic, display logic, choice randomization and question randomization. The survey flow diagram is explored, including block branching and branching based on random number generation. The Getting Started with Qualtrics workshop or equivalent experience is necessary. Note that access to Qualtrics is managed by the Office of Institutional Research and Assessment. Please contact Jonathan Bonilla at JBonilla1@umassd.edu at least three business days prior to this workshop to request access. Students must have a Faculty or Staff advisor request access on their behalf. This workshop will take place via Zoom. A meeting link will be sent to registrants via email on the morning of the event. Contact Rich Legault for more information at 508-999-8799, or email RLegault@umassd.edu. Seating is limited, so please register today!
Join this exciting online event to honor our local community and labor heroes who make a difference in promoting social and economic justice in SE Mass. We will especially recognize unsung heroes with jobs that are not always recognized for the role they play in keeping our community safe and running during the time of COVID.
Topic: Analysis and Implementation of INFOTAXIS as a Practical Strategy to Maximize Target-Search Efficiency Location: Dion 114 Zoom Teleconference: https://umassd.zoom.us/j/94433745094 Please contact Dr. John R. Buck via email at jbuck@umassd.edu for Meeting ID and Passcode. Abstract: Traditionally, search strategies are categorized into one of two types: explorative and exploitative. Explorative search strategies search by exploring an area without using gathered information to guide their search; this strategy type functions best when there is high clutter, which makes detections untrustworthy. Exploitative search strategies search by trusting available information and using it to guide their search; this strategy type functions best when there is low clutter, which makes detections, and thus, available information, more trustworthy. Infotaxis melds the two types of search strategies together by using explorative tactics in high clutter density and exploitative tactics in low clutter density to detect targets faster than established search strategies. It achieves this by maximizing information gain through maximizing entropy reduction. Infotaxis selects which grid cells it measures each iteration by calculating which cell will reduce the amount of entropy or uncertainty the most. Previously, infotaxis has been used to search for a target based on passive odor sensing. This thesis tests a version of infotaxis that instead uses active sensing to capitalize on available information and in turn, speed up the search process. This thesis demonstrates that infotaxis is faster than traditional search strategies and can be implemented into a searching robot using ultrasonic sensors. Through constructing a MATLAB search strategy simulation, the speed of infotaxis is compared to three other search strategies: Maximum A Posteriori (MAP), cycling in order and random searching. Infotaxis is found to be faster than cycling in order and random searching under all tested conditions, and it is slightly faster than MAP when the probability of detection, PD, decreases. Infotaxis is implemented into a real search for a single target by programming an iRobot Create 2 to search a linear row of ten cells with the infotaxis method using an HC-SR04 ultrasonic sensor to make detections. With PD = 0.7 and a probability of false alarm, PD = 0.1, the robot finds the target with infotaxis 100% faster than MAP. By implementing infotaxis using a robot and ultrasonic sensor, this thesis demonstrates that infotaxis can be used as a search strategy in the real world, outside of simulations.

Mechanical Engineering (MNE) SEMINAR DATE: October 29, 2021 TIME: 2:00 p.m. - 3:00 p.m. LOCATION: https://umassd.zoom.us/j/96411224622?pwd=dStHeXhscHBZczE5UHVDek1YYUJ2Zz09 Meeting ID: 964 1122 4622 For Passcode, please contact: hling1@umassd.edu or scunha@umassd.edu SPEAKER: Dr. David Murphy, Assistant Professor Department of Mechanical Engineering, University of South Florida TOPIC: Flapping Flight in Air and Water: Bio-Inspiration from Tiny Insects and Sea Butterflies ABSTRACT: The flapping of wings is a common locomotion technique for tiny animals in both air and water. Insects flap their wings to fly in air, and zooplanktonic marine snails called sea butterflies flap wing-like appendages (called parapodia) to "fly" in water. Further, some tiny insect species are able to locomote via wing flapping in both air and water. Despite the thousand-fold difference in density between air and water, the flight systems of these very different animals show surprising similarities in how the wings move and in how they generate lift. These similarities point towards the possibility of designing a bio-inspired micro-aerial vehicle capable of aerial and aquatic flapping flight, but the fluid dynamics of such flight systems are not well understood. Here I describe our experimental efforts to understand this locomotion system. BIO: Dr. David Murphy began as an Assistant Professor in the USF Department of Mechanical Engineering in 2016. He was awarded a National Academies of Science Gulf Research Program Early Career Research Fellowship in 2017 and received an NSF CAREER award in 2019. His research focuses on biological, ecological, and environmental fluid mechanics, and his work has taken him from Antarctica to Bermuda. Dr. Murphy received his PhD in Civil and Environmental Engineering in 2012 from the Georgia Institute of Technology and subsequently served as postdoctoral fellow in Mechanical Engineering at Johns Hopkins University. He also received an MS in Mechanical Engineering from Georgia Tech and an MPhil in Biological Science from Cambridge University. He completed a double BS in Mechanical and Biomedical Engineering from the University of Alabama at Birmingham. For more information please contact Dr. Hangjian Ling, MNE Seminar Coordinator (hling1@umassd.edu). All are welcome. Students taking MNE-500 are REQUIRED to attend! All other MNE BS and MS students are encouraged to attend. EAS students are also encouraged to attend.
Are you a meditator or curious about meditation? Have questions or experiences to discuss? Want to hear about other people's experiences? MONDAY NIGHT CLASS may be for you! ALL FORMS of yoga, meditation, mindfulness and contemplative practice can provide serious health benefits. Regular practice is needed but can be difficult without a support group. MONDAY NIGHT CLASS is a WEEKLY ONLINE SALON-style meeting for discussion of contemplative practice. It's free and open to all. The "SALON" concept refers to people gathering for lively informal conversation, often on literary and philosophical topics. BEGINNING September 27, we'll meet ONLINE every Monday, from 7:00-8:30pm For info contact Jerry Solfvin, PhD, at JSOLFVIN@UMASSD.EDU FREE & OPEN TO ALL. Register in advance at: https://umassd.zoom.us/meeting/register/tJUpc-muqTsiHdHYkvFounmHQy86Xtxpsykk
