A NOVEL HYPERSPECTRAL LINE-SCAN IMAGING METHOD FOR WHOLE SURFACES OF ROUND-SHAPED AGRICULTURAL PRODUCTS
(2019-01-01)The goal of this research was to develop an online whole surface imaging inspection system for round fruit. Many round-shaped fruits have potential consumer safety issues or quality management problems that current real-time ... -
A VORTEX RING THEORY FOR HORIZONTAL-AXIS WIND TURBINES AND EXPERIMENTAL INVESTIGATION OF THE PERFORMANCE CHARACTERISTICS OF A NOVEL VERTICAL-AXIS WIND TURBINE
(2021-01-01)In conjunction with the continuity equation, the Cauchy equation forms the basis in formulating existing wind turbine (WT) aerodynamics theories such as the actuator disk (ADT), rotating annular stream-tube (RAST) and blade ... -
An active forming grinding method for cylindrical involute gears based on a second-order transmission error model
(Science Research Association, 2019-03-23)An active form-grinding method is proposed to obtain excellent and stable contact performance of cylindrical gears by designing modification forms based on a predesigned controllable second-order transmission error ... -
An active learning Kriging-assisted method for reliability-based design optimization under distributional probability-box model
(Springer Nature, 2020-07-10)Due to lack of sufficient data and information in engineering practice, it is often difficult to obtain precise probability distributions of some uncertain variables and parameters in reliability-based design optimization ... -
An Adaptive Digital Autopilot for Fixed-Wing Aircraft with Actuator Faults
(2021-10-21)This paper develops an adaptive digital autopilot for a fixed-wing aircraft and compares its performance with a fixed-gain autopilot. The adaptive digital autopilot is constructed by augmenting the autopilot architecture ... -
Adaptive Energy Control of Longitudinal Aircraft Dynamics
(American Institute of Aeronautics and Astronautics, 2021-12-29)The Total Energy Control System (TECS) is a method to control airplane longitudinal flight dynamics by regulating energy and energy balance. This multiple input, multiple output method accounts for the highly coupled ... -
An Adaptive PID Autotuner for Multicopters with Experimental Results
(2021-09-27)This paper develops an adaptive PID autotuner for multicopters, and presents simulation and experimental results. The autotuner consists of adaptive digital control laws based on retrospective cost adaptive control implemented ... -
Additive Manufacture of Plasma Diagnostic Components Final Report Phase II
(2018-04-16)There is now a well-established set of plasma diagnostics (see e.g. [3]), but these remain some of the most expensive assemblies in fusion systems since for every system they have to be custom built, and time for diagnostic ... -
Adiabatic Compression of a Compact Torus
(Taylor & Francis, 2017-09-08)A design point is presented here for a prototype fusion neutron source for waste transmutation ( n/s), based on the adiabatic compression of a compact torus (spheromak). The design utilizes the CORSICA (2D equilibrium) and ... -
AERODYNAMIC ANALYSIS OF STATIONARY AND FLAPPING WINGS IN UNSTEADY FLOW ENVIRONMENTS AT LOW REYNOLDS NUMBERS
(2022-01-01)This thesis investigates nonlinear flow physics of flapping wings in unsteady ambient flow environments at low Reynolds numbers, where most birds, insects, and small unmanned aerial vehicles (UAVs) maneuver or operate, ... -
Aluminum-alloyed lightweight stainless steels strengthened by B2-(Ni,Fe)Al precipitates
(Elsevier, 2021-05-08)The age hardenability of Al-alloyed lightweight stainless steels with the base chemical composition Fe–10.5Cr–3Al (wt.%) and Ni concentrations in the range 3–15 wt.% was studied. Alloys containing 3% and 6% Ni exhibited ... -
Analysis of Wake Structures Behind an Oscillating Square Cylinder Using Dynamic Mode Decomposition
(AIAA Aviation Forum, 2016)A dynamic mode decomposition (DMD) algorithm has been used to analyze the vortex structures shedding from an oscillating square cylinder. The flow fields are simulated using a high-order accurate flux reconstruction/correction ... -
An approach to rapid distributed manufacturing of broad spectrum anti-viral griffithsin using cell-free systems to mitigate pandemics
(2022-12-20)This study describes the cell-free biomanufacturing of a broad-spectrum antiviral protein, griffithsin (GRFT) such that it can be produced with consistent purity and potency in less than 24 hours. We demonstrate GRFT ... -
Assessment of Online Professional Development on Faculty Teaching Virtually
(American Society for Engineering Education, 2021-07-26)This evidence-based practice paper discusses an assessment of a recent faculty training in the summer of 2020, due to COVID-19, at a medium size university and its impact on the faculty teaching in the fall 2020 semester. ... -
Bateson Information Revisited: A New Paradigm
(MDPI, 2020-05-11)The goal of this work is to explain a novel information paradigm claiming that all information results from a process, intrinsic to living beings, of self-production; a sensory commensurable, self-referential feedback ... -
Biocompatible Nanocapsules for Self-Healing Dental Resins and Bone Cements
(ACS, 2022-08-31)Bone cements and dental resins are methacrylatebased materials that have been in use for many years, but their failure rates are quite high with essentially all dental resins failing within 10 years and 25% of all ... -
