Flexible polymer composite films are prepared by a solution cast method with polar polyvinylidene fluoride (PVDF) or non-polar epoxy as the matrix. BaTiO3 nanoparticles and nanofibers large aspect ratio used dielectric fillers after surface modification polydopamine. The effects of filler shape, polarity matrix on microstructure, constants breakdown strength composites investigated in detail. Surface polydopamine improves compatibility between well passivating surfaces BaTiO3. At same volume...
A carbon nanotube (CNT)/polymer composite is prepared with a CNT array using an electrospinning method and hot-pressing technology. This exhibits stable high dielectric permittivity low loss over wide frequency range, in addition to large energy density. Detailed facts of importance specialist readers are published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset. They made available submitted by the authors. Please note: The publisher responsible for...
In this research, double-blended materials such as fly ash and slag are used binders, basalt fibers (BF) mixed in varying volume fractions (0.2%, 0.4%, 0.6%, 0.8%, 1.0%) relative to the of concrete. Besides, sodium silicate (Na2SiO3) hydroxide (NaOH) served activators. The study investigates freeze-thaw resistance, microstructure, performance mechanism, internal damage distribution fiber geopolymer concrete (BFGPC) through cycle tests coupled with sulfate attack, SEM, energy dispersive...
Students' dropout rate is a key metric in online and open distance learning courses. We propose time-series classification method to construct data based on students' behaviour activities number of modules. Further, we prediction model the time series forest (TSF) algorithm. The proposed predictive interaction independent objectives subject domains. enables rates without requirement for pedagogical experts. Results show that accuracy two selected datasets increases as portion used grows....
Data streams, which can be considered as one of the primary sources what is called big data, arrive continuously with high speed. The biggest challenge in data streams mining to deal concept drifts, during ensemble methods are widely employed. ensembles for handling drift categorized into two different approaches: online and block-based approaches. disadvantage lies difficulty tuning block size provide a tradeoff between fast reactions drifts. Motivated by this challenge, we put forward an...
Cipadonoid A ( 1), a novel limonoid with an unprecedented skeleton, was isolated from the leaves of Cipadessa cinerasecns. Its structure and relative configuration were determined by spectroscopic analysis computer modeling. 1 represents new type limonoid, characterized rearranged tetrahydropyranyl ring B incorporating usually exocyclic C-30. possible biosynthetic pathway also proposed.
In order to enhance the accuracy of discrete element numerical simulations in processing small-seed particles, it is essential calibrate parameters seeds within software. This study employs a series physical tests obtain and contact red clover seeds. A model established. Plackett–Burman Design, steepest ascent, Central Composite Design experiments are sequentially conducted. The simulation deviation resting angle employed as evaluation criterion for parameter optimization. results indicate...
Abstract Phytochemical investigation of whole plants Euphorbia pilosa led to the isolation and identification two new daphnane‐diterpenoid glucosides, euphopilosides A B ( 1 2 , resp.), a ent ‐abietane, euphopilolide 3 ), together with eight known compounds. Compounds are first daphnane‐type diterpenoid glycosides. Their structures were elucidated by combination 1D‐ 2D‐NMR, MS analyses, acid hydrolysis. – 9 evaluated for their in vitro cytotoxicities against five human tumor cell lines,...
Abstract The deep forest presents a novel approach that yields competitive performance when compared to neural networks. Nevertheless, there are limited studies on the application of time series classification (TSC) tasks, and direct use cannot effectively capture relevant characteristics series. For that, this paper proposes cascade (TSCF), model specifically designed for TSC tasks. TSCF relies four base classifiers, i.e., random forest, completely shapelet diverse representation canonical...
Abstract The accurate identification of individual sheep is a crucial prerequisite for establishing digital farms and precision livestock farming. Currently, deep learning technology provides an efficient non-contact method identity recognition. In particular, convolutional neural networks can be used to learn features faces determine their corresponding identities. However, the existing face recognition models problems such as large model size, high computational costs, making it difficult...
Thirteen previously undescribed lindenane sesquiterpenoid dimers (LSDs), named chlorahololides G-S (1-13), were isolated from the whole plants of Chloranthus holostegius var. shimianensis, along with ten known analogues (14-23). The structures and absolute configurations compounds 1-13 elucidated through comprehensive spectroscopic analysis, NMR electronic circular dichroism (ECD) calculations, X-ray single-crystal diffraction. Chlorahololide G (1) represents first instance LSDs formed via a...
Abstract Three new pentacyclic steroids, taccalonolides W–Y ( 2 – 4 , resp.), have been isolated from the whole plants of Tacca plantaginea. Their structures were elucidated on basis spectroscopic methods including extensive 1D‐ and 2D‐NMR experiments.
