Advances in In-Situ Calibration of Attitude and Doppler Sensors for Precision Oceanographic Submersible Navigation
(2005)This paper reviews the development and experimental evaluation of three techniques for estimating the alignment matrix of Doppler sonars, which are commonly used for precision navigation of oceanographic submersibles, ... -
Auditory and Vestibular Control of Inverted Pendulum Dynamics in Spatial Orientation
(2019)Human standing balance requires continuously nulling the tendency to fall like an inverted pendulum, and this process relies on the convergence of information from multiple sensory modalities including vestibular, vision, ... -
Automatic Detection and Segmentation of Robot-Assisted Surgical Motions
(2007)Robotic surgical systems such as Intuitive Surgical's da Vinci system provide a rich source of motion and video data from surgical procedures. In principle, this data can be used to evaluate surgical skill, provide ... -
Camera Trackers
(1999)Tracking an object's location with inertial sensors works well over short time periods, but sensor drift and errors in integration cause errors to accumulate exponentially. Images, in contrast, work very well to determine ... -
A Combined Electrochemical-Biological System for the Production of Liquid Fuel from CO2
(2022)Biological photosynthesis is the origin of our liquid transportation fuels, from petroleum to corn ethanol. Biological photosynthesis has an efficiency of approximately 1% for the conversion of photons from sunlight to ... -
Competence Assessment and Automated Feedback for Ultrasound-Guided Intervention Training
(2018)There is an ongoing shift in the medical education community from a time-based model of medical education to a competency-based model. In the competency-based model, trainees’ performance must be continually monitored. But ... -
COMPUTER GRAPHICS OPTIQUE: Optical Superposition of Projected Computer Graphics
(2001)We present some ideas and demonstrations for a hybrid projector-based rendering and display technique we call Computer Graphics Optique. Instead of partially overlapping projected images to achieve a wide-area display, ... -
Countercurrent Flowthrough Pretreatment of Cellulosic Biomass
(2015)The aim of my work as a Link Fellow was to develop an analytical framework incorporating fluid mechanical, thermodynamics and kinetic factors to determine the feasible domains of hot water FT pretreatment. I addressed ... -
Creating Geo-Specific Road Databases for a Real-Time Interactive Driving Simulator
(2005)Geo-specific road database development is important to a driving simulation system and a very labor intensive process. Road databases for driving simulation need high resolution and accuracy. Even though commercial ... -
Defining and Refining Frameless Rendering
(1997)Frame1ess Rendering (FR) is a rendering paradigm which performs stochastic temporal filtering by updating pixels in a random order, based on most recent available input data, and displaying them to the screen immediately ... -
Deployment of an Inexpensive, Reliable, and Low Carbon Electric Power System Requires New Modeling Tools.
(2013)The electricity system is of fundamental importance to the decarbonization of the entire energy system, as fuel switching away from oil and natural gas and towards electricity is a key decarbonization statregy. The scenarios ... -
The Design and Evaluation of Distributed Graph-Theoretic Heuristics for Computing Pairwise Interactions of Moving Entities
(1998)In recent years the focus of training simulations, particularly those in the defense domain, has been on increasing the number of simulated entities. This focus, coupled with the requirement for geographically ... -
Design and simulation of intelligent control algorithms for bimanual robot-assisted retinal surgery training system
(2022-10)Vitreoretinal surgery is among the most delicate surgical tasks in which physiological hand tremor may severely diminish surgeon performance and put the eye at high risk of injury. Unerring targeting accuracy is required ... -
Design and Synthesis of Low-bandgap Polymers for Organic Photovoltaic Applications
(2015)This research at UCLA focused on the design and synthesis of novel conjugated polymers as the electron-donor material for photovoltaic devices. By careful molecular design both on the polymer backbone and the side chains, ... -
Developing /11 Situ Dissolved Inorganic Carbon Dioxide Instrumentation
(2019)The ocean carbon system plays a critical role in regulating carbon dioxide content in the atmosphere. With increased anthropogenic carbon input, it is even more important to understand the system through measurements, ... -
Developing High-Capacity Rechargeable Batteries Based on Lithium-Sulfur Chemistry
(2020)The development of portable and transportation applications, such as the booming electrical vehicles, heavily relies on high-energy battery technologies. As the current Li-ion batteries approach the energy storage limit, ... -
