Seminar: Engineering Cutting-Edge Solutions at Martin Defense Group
Charlie Field Mechanical Engineer Martin Defense Group, Honolulu, Hawaii Charlie Field is a graduate of the Ocean and Resources Engineering department, and earned his Master’s Degree from UH in 2012. During his time in the program, he interned at a local engineering company, Navatek, and was hired full-time as a Mechanical Engineer. Navatek is now Martin Defense Group, a leader in developing cutting-edge solutions in the defense and maritime industries. Leading the way in research, engineering, design, and innovation, the team of scientists and engineers believe in finding solutions that don’t just innovate, but that spark lasting change. Through partnerships
Seminar: Learning what tickles your flow from data
Benjamin Herrmann Research Associate Department of Mechanical Engineering at University of Washington Institute of Fluid Mechanics at Technische Universität Braunschweig Many fluid flows behave as selective amplifiers of external disturbances –where most perturbations are damped out, a few favored excitation patterns lead to largely amplified responses. Resolvent analysis is a technique to identify these most-responsive forcings along with the corresponding most-amplified responses, based on the governing equations of the system. Interest in the method has continued to grow during the past decade due to its potential to reveal structures in turbulent flows, and to guide sensor/actuator placement for flow control
Seminar: Pacific Shipyards International, Project Management in Ship Repair
Troy Keipper, PE Programs Vice President Pacific Shipyards International (PSI) Pacific Shipyards International is a locally owned and operated full-service shipyard in Hawaii, with long-standing roots to the region dating back to 1944. PSI is a substantial and integral part of the Navy’s efforts to maintain the active surface ships and submarines which are home ported in Pearl Harbor. Our customers include the U.S. Navy, U.S. Army, Coast Guard, Military Sealift Command National Oceanic & Atmospheric Association, University of Hawaii, and many commercial marine operators and contractors. PSI’s new shipyard facility, located within 5.3 miles of Pearl Harbor Naval Shipyard
Seminar: Buoyancy controlled float swarms for distributed sensing in coastal waterways
Zoom Meeting ID______ 977 4017 0381 Passcode: meseminarTrevor Harrison, Ph.D. National Science Foundation Fellow Department of Mechanical Engineering University of Washington Abstract Buoyancy-controlled underwater floats have produced a wealth of in situ observational data from the open ocean. When deployed in large numbers, or ‘swarms’, floats offer a unique capacity to simultaneously map, in three-dimensions, environmental variables, such as currents, temperatures, and dissolved oxygen. This sensing paradigm is equally relevant in coastal waterways, yet remains underutilized due to economic and technical limitations of existing platforms. To that end, we have developed the microFloat, a buoyancy-controlled float designed specifically for the strong currents and density gradients observed in
Seminar: Bioinspired Propulsion and Sensing Systems Enabling Next Generation Underwater Vehicles
Zoom Meeting ID______ 944 3679 2959 Passcode: ore792Michael Krieg, PhD Assistant Professor Department of Ocean & Resources Engineering University of Hawai'i at Mānoa Even the most robust and sophisticated underwater robots pale in comparison to the performance of the ocean’s natural inhabitants, as many of which seem to traverse turbulent environments with ease and also demonstrate effective long range migration patterns. This talk analyzes a novel propulsion mechanism inspired by the locomotion of squid and jellyfish; whereby, finite fluid jets are ejected from a flexible internal cavity in a periodic fashion. Vortex ring formation, which is associated with expelled jets starting from rest, causes the thrust associated with this
Seminar: Martin Defense Group Overview
Holmes 247 2540 Dole Street, Honolulu, HI, United StatesCharlie Field Senior Engineer Martin Defense Group Location Information: **this seminar will be held both in person (Holmes Hall 247) and over Zoom** Meeting ID: 960 4654 5799 Passcode: OREseminar https://hawaii.zoom.us/j/96046545799 The mission of Martin Defense Group (MDG) is to convert research into products by leveraging emerging technologies and applying them to National problem sets with speed, trust, and expertise. We are built upon core engineering expertise that utilizes the latest design tools including: CFD analysis, finite element analysis, sea-keeping analysis, mechanical systems design, hydro-mechanical simulation, and concept design.

Seminar: Miniature Soft Robotic Systems Towards Complex Fluidic Environments
Bilger Hall 150 2545 McCarthy Mall, Honolulu, HI, United StatesTianlu Wang Assistant Professor Department of Mechanical Engineering University of Hawai’i at Mānoa Location Information **This seminar will be held both in person (Bilger Hall 150) and over Zoom** https://hawaii.zoom.us/j/95081858686 Meeting ID: 950 8185 8686 Passcode: OREseminar The emerging field of miniature soft robots with unprecedented maneuverability, adaptation, and safe interactions with surrounding environments has endowed new platforms to overcome critical challenges in hard-to-reach marine and biomedical scenarios. Focusing on system-level construction, we first synergized soft actuators and bio-inspired structures to create small-scale soft robots emulating larval zebrafish and jellyfish. A class of magnetically actuated laval fish-like milliswimmers was investigated
