Investigating The Harmonic Content Of A Pwm Inverter With Varying Modulation Index, Peter Makolo

Tanzania Journal of Engineering and Technology (TJET)

Photovoltaic energy is a clean and endless vital renewable energy. In order to generate electricity from solar energy an inverter is required to transform the direct current into alternating current. Also, with the emerging of new ultra-high voltage direct current transmission technology, the rectification and inverters play a great role. Most three-phase two-level inverters draw harmonics that cause heat dissipation, waveform distortions hence affect the electrical loads. Knowing that Total Harmonic Distortion content of voltage source inverter is important and must be within the allowable range. Several schemes are suggested to mitigate the distortion in order to produce as much …

Ainr: Automated Intrinsic Non-Rigid Registration For Accuracy Qualification Of Complex Freeform Products In 3d Printing, Weizhi Lin, Qiang Huang

Faculty Research, Scholarly, and Creative Activity

Non-rigid shape registration identifies the optimal non-rigid transformation between an actual product and its intended design to characterize their geometric dissimilarities. This transformation is usually determined by iteratively minimizing point-wise distances to match points with point-wise rigid motion. However, freeform products may exhibit complex spatial patterns of shape deviation, leading to premature iteration termination due to tradeoffs among local regions. One solution is to segment the complex design into semantic features and perform segment-wise rigid registration. Segment boundaries are typically placed along high-curvature regions, where deviations are more likely occur in 3D printing. However, since boundaries are generally more prone …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Hagfish produce extraordinary slime as a defense mechanism, releasing exudate from glands that rapidly form a fibrous, soft, ultra-dilute, water-capturing network upon contact with seawater (up to 10 000 times its original volume). The gland thread cell (GTC) produces high-strength protein threads (filament diameter df = 1–3 µm) meticulously coiled into skeins (coil diameter Do ∼ 150 µm) that rapidly unravel upon deployment to reveal their hidden length (Lf = 15 cm), forming a cohesive fibrous slime network through interaction with mucin vesicles and seawater. To date, no engineered material is able to replicate the fiber …

Fiber Recruitment Drives A Phase Transition Of Cell Polarization At A Critical Cell Spacing In Matrix-Mediated Tissue Remodeling, Xiangjun Peng, Yuxuan Huang, Wenyu Kong, Yanan Du, Elliot L Elson, Xi-Qiao Feng, Guy M Genin

2020-Current year OA Pubs

Biological tissues exhibit sharp phase transitions where cells collectively transition from disordered to ordered states at critical densities. We demonstrate through bio-chemo-mechanical modeling that this emergent behavior arises from a nonmonotonic dependence on nonlinear extracellular matrix (ECM) mechanics: mechanical communication between cells is optimized at intermediate stiffness values where cells can both generate sufficient forces and create strain-stiffened tension bands in the ECM. This balance establishes a critical cell spacing threshold for cell-cell communication ([Formula: see text]100 to 200 [Formula: see text]m) that is conserved across experimental observations for a broad range of cell types and collagen densities. Our model …

The circadian clock controls 24-h rhythmic processes. However, how genetic variations outside clock genes impact peripheral diurnal rhythms remains largely unknown. Here, we find that genetic variation contributes to different diurnal patterns of hepatic gene expression in both humans and mice. Nutritional challenges alter the rhythmicity of gene expression in mouse liver in a strain-specific manner. Remarkably, genetics and nutrition interdependently control more than 80% of rhythmic gene and enhancer-promoter interactions (E-PIs), with a noncanonical clock regulator, estrogen-related receptor gamma (ESRRγ), emerging as a top transcription factor during motif mining. Knockout of Esrrγ abolishes strain-specific metabolic processes in response to …
