Supercapacitors offer superior cycle life and high power densities, but as energy storage devices, they are limited by self-discharge processes manifested large potential decay leakage current, resulting in loss of stored low charging efficiency. To minimize Faradaic side reactions, this Letter has incorporated a sulfonate ion-exchange resin separators to trap impurities thereby suppress supercapacitors with PEDOT redox electrodes. The versatile separator design is generally applicable...

Micro-supercapacitors are poised to serve as on-chip power sources for electronics. However, the challenge simultaneously increase their power, energy, and lifetime demands new material combinations beyond current carbon-based systems. Here, we demonstrate that electro-deposition of an open-shell conjugated polymer with reduced graphene oxide achieves electrodes capacitance up 186 mF cm−2 (372 F cm−3). The extended delocalization within stabilizes redox states facilitates a 3 V wide...

Then research status FGD introduced, especially comprehensive utilization gypsum. Finally, some suggestions are put forward to solve problems existing application gypsum, which provides a reference for further and development.

This work presents a vital sign monitoring interface combining electrocardiogram (ECG) and reflective photoplethysmography (PPG) acquisition on stretchable kinesiology tapes (KTs). The integrated textile bands are less prone to electrode misplacement deliver high-quality diagnostic ECG signals with dry electrodes. PPG measured over the subclavian artery is used track blood oxygen saturation, in combination ECG, enables determination of pulse transit time inference pressure. multimodal...

Abstract As the consequences of building fire evacuation continue to be severe, some experts and scholars have proposed combine information modeling (BIM) technology with geographic system (GIS) construct a three-dimensional space scene evacuation. BIM has advantages refined modeling, help software, people its characteristics are simulated, GIS powerful spatial analysis functions analyze path. In this kind simulation method, two technologies complement each other achieve quantitative...

Accurate assessment of spasticity is crucial for physicians to select the most suitable treatment patients. However, current clinical practice standard limited by imprecise scales relying on perception. Here, we equipped clinician with a portable, multimodal sensor glove shift bedside evaluations from subjective perception objective measurements. The measurements were correlated biomechanical properties muscles and revealed dynamic characteristics spasticity, including catch symptoms...

As clinical evaluations of neuromuscular disorders such as hypertonia mostly rely on perception-based scales, the imprecise subjective ratings make it difficult to accurately monitor treatment progress. To promote objective evaluation, this work used a multi-modal sensing glove in double-blind study enable sensitive monitoring medication effects across 19 participants. The biomechanical measurements from effectively distinguished patient cohorts receiving baclofen or placebo with 95%...

Accumulation of liquid and solid impurities will result in increase overall pressure drop remarkable decrease pipeline flow efficiency during the process multiphase pipelines. Hence, it is necessary to conduct pigging operation pipelines so ensure transportation efficiency. According two-phase behavior under a operation, four flowing sections could be present horizontal isothermal gas-liquid Then mathematical model was built up this paper by use mixed Eulerean-Lagrangean method achieve...

In this paper, we took Karakoram range Himalayas as study area, and derived lake area 2001, 2014, 2017 with semantic segmentation algorithm. Firstly, five high-resolution images Mount Lucania were collected from Google Earth. Secondly, each image was labelled, 80000 training size 256×256 pixels using augmentation approach. Thirdly, a model stacking network U-Net SegNet based on these to extract trained. Then, another...

Abstract The effects of different grinding parameters on the glass edge quality and bending strength were investigated, including wheel speed, feeding rate, mesh shape. results show that Weibull modulus increase with increasing speed then decrease. rate has a similar influence modulus. There is an optimal matching relationship between as well rate. mesh. Taper cup more suitable to obtain smoother stronger glass.

Abstract In nature, the vertical and horizontal deformation components happen simultaneously for most geohazards, which sometimes bring disasters to human beings. As an advanced radar interferometry technique, InSAR (Interferometric Synthetic Aperture Radar) can efficiently obtain ground information at a global scale, but it only along LOS (line of sight) direction. To extract components, existing methods need least three-track measurements or azimuth measurements. However, is generally...

Spasticity is a neuromuscular disease manifested as increased muscle tone. Clinical spasticity evaluation such the Modified Ashworth Scale or Tardieu depends on perception and highly subjective. To improve objectivity in evaluation, multimodal glove used to quantify For patients with asymmetric tones present agonist antagonist muscles, shows different trends over two-month monitoring period. This work that it necessary segment analysis for groups each group may progress differently treatment.

摘要: 弹性环式支承结构作为航空发动机中典型的弹性支承结构,其配合紧度很大程度上影响支承系统的刚度,进一步影响转子系统动力学特性,但相关研究尚少。因此,首先建立了弹性环式支承结构的有限元模型,分析了配合紧度对其刚度及强度特性的影响,并发现可通过分段刚度出现时的位移与凸台高度之间的关系来判断弹性环式式支承结构的配合紧度,然后搭建了相关实验台与测试结果对比,验证了仿真结果的正确性,最后建立了考虑弹性环式支承结构配合紧度的转子系统有限元模型,研究了其对转子系统动力学特性的影响。研究表明:过盈配合下的弹性环式支承结构会导致转子系统临界转速升高,间隙配合会导致临界转速降低,并会引起转子系统非线性振动,研究结果可为采用弹性环式支承结构的转子支承系统设计提供理论参考。
