Mathematical modeling of heat generation and transport in lithium/polymer‐electrolyte batteries for electric vehicle applications has been conducted. The results demonstrate that thermal management may not be a serious problem under low discharge rates. However, high rates, the temperature battery increase remarkably if thickness cell stack exceeds certain value. Also, due to conductivity polymer, improvement cooling conditions is an effective means improving removal large‐stack systems. For...
Abstract Purpose Epilepsy is one of the most disabling neurological disorders, which affects all age groups and often results in severe consequences. Since misdiagnoses are common, many pediatric patients fail to receive correct treatment. Recently, 18 F-fluorodeoxyglucose positron emission tomography ( F-FDG PET) imaging has been used for evaluation epilepsy. However, epileptic focus very difficult be identified by visual assessment since it may present either hypo- or hyper-metabolic...
Fault localization is one of the most important issues for modular multilevel converters (MMCs) consisting numerous switches. This article proposes an isolation forest (IF) based submodule (SM) switch open-circuit fault method MMCs. Based on continuous sampling SM capacitor voltages, a number trees (ITs) are produced to construct IFs Through comparison IFs' outputs, faulty can be effectively localized. The proposed IF-based only requires voltages in MMC concise low-data-volume tree models,...

Multi-view classification based on evidence theory aims to enhance result reliability by effectively quantifying prediction uncertainty at the level, particularly when dealing with low-quality views. However, these methods face limitations in real-world applications due sensitivity of estimated view distribution, leading two main issues: 1) difficulty making clear judgments about whether trust predictions vague scores, and 2) potential negative impact integrating information from views...

Mode filters are fundamental elements in a mode-division multiplexing (MDM) system for reducing modal cross-talk or realizing routing. However, the previously reported silicon mode can only filter one specific at time and multiple modes filtering usually needs cascade of several filters, which is adverse to highly integrated MDM systems. Here, we propose unique concept realize compact, scalable flexible based on backward conversion gratings elaborately embedded multimode waveguide. Our...
Relentless semiconductor scaling and ever increasing device integration have resulted in the exponentially growing size of back-end design, which makes simulation very time- resource-consuming.

However, unlike tasks, most problems are mathematically physically well-defined, e.g., power delivery network sign off post-layout circuit It then brings broad interests community where how deploy...
