In this paper, a fuzzy-logic-control (FLC) based maximum power point tracking (MPPT) algorithm for photovoltaic (PV) systems is proposed. The variation and output voltage are chosen as inputs of the proposed FLC, which simplifies calculation. Compared with conventional perturb observe (P&O) method, FLC-based MPPT can simultaneously improve dynamic steady state performance PV system.

Type-II Dirac/Weyl points, although impermissible in particle physics due to Lorentz covariance, were uncovered condensed matter physics, driven by fundamental interest and intriguing applications of topological materials. Recently, there has been a surge exploration such generic points using various engineered platforms including photonic crystals, waveguide arrays, metasurfaces, magnetized plasma polariton micropillars, aiming towards relativistic quantum emulation understanding exotic...
In comparison with conventional lasers, topological lasers are more robust and can be immune to disorder or de-fects if lasing occurs in topologically protected states. Previously reported were almost exclu-sively based on the first-order photonic insulators. Here, we show that achieved zero-dimensional corner state a second-order insulator, which is Kagome wave-guide array rhombic configuration. If gain present of structure, where resides, stable this achieved, lowest possible threshold,...
Potassium ion channels are the structural basis for excitation transmission, heartbeat, and other biological processes. The selectivity filter is a critical component of potassium channels, whose structure crucial to realizing their function.

Effective charging techniques must consider factors such as efficiency, lifecycle, time (CT), and battery temperature. Currently, most strategies primarily focus on CT losses (CL), overlooking the crucial influence of temperature life. Therefore, this study proposes a constant temperature–constant voltage (CT-CV) method based minimizing energy losses. The process is divided into three stages. In first stage, current (CC) implemented using 2C rate that aims to expedite but may result in rapid...

Graph visualization has been widely used to understand and present both global structural local adjacency information in relational data sets (e.g., transportation networks, citation or social networks). Graphs with dense edges, however, are difficult visualize because fast layout good clarity not always easily achieved. When the number of edges is large, edge bundling can be improve clarity, but many cases, could still too cluttered permit correct interpretation relations between nodes. In...
