Precision Grasp Using An Arm-Hand System As A Hybrid Parallel-Serial System: A Novel Inverse Kinematics Solution, Shuwei Qiu, Shuwei Qiu Ph.D., P.Eng.
Electrical and Computer Engineering Publications
In this letter, we present a novel inverse kinematics (IK) solution for a robotic arm-hand system to achieve precision grasp. This problem is kinematically over-constrained and to address the issue and to solve the problem, we propose a new approach with three key insights. First, we propose a human-inspired thumb-first strategy and consider one finger of the robotic hand as the “thumb” to narrow down the search space and increase the success rate of our algorithm. Second, we formulate the arm-thumb serial chain as a closed chain such that the entire arm-hand system is controlled as a hybrid parallel-serial system. …

Improving The Power Outage Resilience Of Buildings With Solar Pv Through The Use Of Battery Systems And Ev Energy Storage, Huangjie Gong, Dan M. Ionel
Improving The Power Outage Resilience Of Buildings With Solar Pv Through The Use Of Battery Systems And Ev Energy Storage, Huangjie Gong, Dan M. Ionel
Electrical and Computer Engineering Faculty Publications
Buildings with solar photovoltaic (PV) generation and a stationary battery energy storage system (BESS) may self-sustain an uninterrupted full-level electricity supply during power outages. The duration of off-grid operation is dependent on the time of the power fault and the capabilities of the home energy management system (HEMS). In this paper, building resilience is quantified by analyzing the self-sustainment duration for all possible power outages throughout an entire year. An evaluation method is proposed and exercised on a reference house in California climate zone 9 for which the detailed electricity usage is simulated using the EnergyPlus software. The influence of …

The vitamin D hormone, 1,25dihydroxyvitamin D3 (1,25(OH)2D3), and related compounds derived from vitamin D3 or lumisterol as a result of metabolism via the enzyme CYP11A1, have been shown, when applied 24 hours before or immediately after UV irradiation, to protect human skin cells and skin from DNA damage due to UV exposure, by reducing both cyclobutane pyrimidine dimers (CPD) and oxidative damage in the form of 8‐oxo‐7,8‐dihydro‐2’‐ deoxyguanosine (8‐OHdG). We now report that knockdown of either the vitamin D receptor or the endoplasmic reticulum protein ERp57 by siRNA abolished the reductions in UV‐induced DNA damage with 20‐hydroxyvitamin D3 or 24‐hydroxylumisterol3, …

Civil and Environmental Engineering Faculty Publications
Loblolly pine (Pinus taeda L.) is a commercially important timber species planted across a wide temperature gradient in the southeastern U.S. It is critical to ensure that the planting stock is suitably adapted to the growing environment to achieve high productivity and survival. Long-term field studies, although considered the most reliable method for assessing cold hardiness of loblolly pine, are extremely resource-intensive and time-consuming. The development of a high-throughput screening tool to characterize and classify freeze tolerance among different genetic entries of seedlings will facilitate accurate deployment of highly productive and well-adapted families across the landscape. This study presents a …

Optimal Steering Of Nonredundant Cmg Configurations For Spacecraft Attitude Control, Victor Hakim
Optimal Steering Of Nonredundant Cmg Configurations For Spacecraft Attitude Control, Victor Hakim
Mechanical Engineering Master's Theses
This thesis presents the problem of optimal steering with three or two single-gimbal control moment gyros (SGCMGs). Most SGCMG configurations use more than three rotors so that the resulting Jacobian always has a nontrivial nullspace. We consider the specific case of a four-CMG pyramid configuration where only three or two CMGs are operational. We use the Gauss pseudospectral method to find the optimal gimbal angle trajectories of the CMGs and the states of an agile spacecraft subject to mission-specific constraints. We do so while either minimizing time or maximally avoiding the angular-momentum singularities. The proposed steering method is implemented in …

Teachers As Instructional Designers: Unearthing The Essence Of The Primary School Curriculum For Delivery Within The Remote Learning Classroom, Angela Gonzalez, Michael Poole
Journal of Practitioner Research
Moving our elementary curriculum to emergency remote instruction presented numerous challenges to our elementary school, as teachers recognized that elementary-age children could not be expected to spend the amount of time on computer screens that they had spent in face-to-face classrooms. Working with our colleagues, we adopted a “less is more” approach, using inquiry processes to make systematic and informed choices as to which state standards would be covered. We acted as instructional designers to develop coherent learning units for remote instruction, using inquiry processes to study the effectiveness of our lessons and adjust instruction accordingly. This work could only …

Influence Of Deposition Parameters On Optical Properties Of Sputtered Tungsten Oxide Films, Christopher Mkirema Maghanga
International Journal of Thin Film Science and Technology
Thin films of tungsten oxide were deposited on glass substrates at different temperatures and O2/Ar ratios using DC Magnetron sputtering system. The samples were characterized using x-ray diffractometry and spectrophotometer structurally and optically respectively. Analysis of the results reveals dependence of structure on thickness and temperature. The O2/Ar ratio is also found to influence the optical properties appreciably for the entire wavelength range studied. Visual inspection of the films show that O2/Ar ratio influences the coloration of the film which varies from clear to dark blue for high to low O2/Ar ratios respectively.
