Optimization of LCL Filter Grid-Connected Inverters

Academic Journal of Science and Technology, 2023
 The increasing use of grid-connected inverters in power systems, driven by renewable energy growth and high-voltage, high-power open-loop devices, poses challenges due to PWM modulation generating harmful high-frequency harmonic currents. Optimizing parameter selection becomes crucial.LCL grid-connected inverters, as third-order systems, suffer from ...

Nutrimental Determinants of Chronological Aging and Competitiveness in the snf1Δ Warburg Model

Yeast, EarlyView.
Deletion of SNF1 in Saccharomyces cerevisiae alters chronological aging in a nutrient‐dependent manner, shortening lifespan under low‐nutrient conditions and extending it under high‐glucose and high‐amino‐acid conditions. Under nutrient‐rich conditions, the snf1∆ strain also showed an approximately 2‐log increase in competitiveness relative to the wild

Survey on differential estimators for 3d point clouds

Computer Graphics Forum, EarlyView.
Abstract Recent advancements in 3D scanning technologies, including LiDAR and photogrammetry, have enabled the precise digital replication of real‐world objects. These methods are widely used in fields such as GIS, robotics, and cultural heritage. However, the point clouds generated by such scans are often noisy and unstructured, posing challenges for ...

Tangent Blow‐Ups for Processing Non‐Manifold Geometry

Computer Graphics Forum, EarlyView.
Abstract Many geometry processing pipelines implicitly assume their input data is a manifold, or is sampled from one, with a unique tangent plane at every point. Geometric data, however, routinely contains sharp features like edges, corners, self‐intersections, branching junctions, and other singularities, rendering standard methods ill‐defined at ...
