An ultrahigh-strength textile fiber-supported Schiff base copper complex PEEK-SB@Cu(II) was prepared by chloromethylation and amination of a commercially available poly(ether ether ketone) (PEEK) fiber, followed functionalization acetate chelation treatment. The fibers derived from the preparation stages catalytic runs were characterized using diverse techniques to investigate these changes. Moreover, incorporated with NaBH4 presented effective photocatalytic activities for fast exhaustive...
Introduction: Two-dimensional (2D) materials, such as MXene (Ti3C2Tx), have garnered extensive attention in recent years due to their exceptional performance across various domains. The flake size of Ti3C2Tx notably influences its specific surface area, a pivotal factor interfacial interactions within electrochemistry. Method: Presently, modifying the bulk typically involves complex and costly processes, like ultrasonic treatment isolation. Leveraging preparation principle MXenes, which...
In this paper, a self-compensation method for improving the accuracy of roll angle measurement linear stage caused by non-parallelism dual-beam due to time-dependent mechanical deformation support is proposed and integrated into 5-DOF sensor verify feasibility. The between two laser beams online real-time monitored pair small autocollimator units. Through ray-tracing analysis, separate moving induced error determined. A series experiments under different supporting forces ambient conditions...
The Large High Altitude Air Shower Observatory (LHAASO) has three sub-arrays, KM2A, WCDA and WFCTA. flux variations of cosmic ray air showers were studied by analyzing the KM2A data during thunderstorm on 10 June 2021. number shower events that meet trigger conditions increases significantly in atmospheric electric fields, with maximum fractional increase 20%. rates (increases or decreases) are found to be strongly dependent primary zenith angle. secondary particles significantly, following...
Currently, the widely used pendulum-type precision level cannot be miniaturized because reducing size of pendulum will reduce its displacement so as to decrease measurement accuracy and resolution. Moreover, commercial can only sense one direction. In this paper, an innovative compact high-accuracy dual-axis is proposed. Based on optical principle light refraction reference invariant liquid level, no more needed. addition, based transmission design, there reflection signal interfere with...
Though emotion speech recognition has gained increasing interest in the field of Human Computer Interaction, it is still a challenge to automatically determine state type and boundaries each emotionally salient segment continuous speech, which named as Automatic Emotion Variation Detection (AEVD). In this task, input utterances are not pre-segmented may contain variations. This paper proposes Multi-timescaled Sliding Window based AEVD (MSW-AEVD). Firstly, sliding window with fixed-length...
Emotion recognition from speech plays an important role in developing affective and intelligent Human Computer Interaction. The goal of this work is to build Automatic Variation Detection (AEVD) system determine each emotional salient segment continuous speech. We focus on emotion detection angry-neutral speech, which common recent studies AEVD. This study proposes a novel framework for AEVD using Multi-scaled Sliding Window (MSW-AEVD) assign class window-shift by fusion decisions all the...
<title>Abstract</title> During the study, we investigate and compare spatial prediction result of landslide hazards with a relative less-used model BFT (Best-first Decision Tree) its three integrated models RSBFT (RandomSubspace ensemble based BFTree), MBBFT (MultiBoost BFT), BABFT (Bagging BFT) in Meixian County, Baoji city, Shaanxi province, China. BFTree is machine learning technique by optimizing split nodes standard decision tree. Integrated an excellent method combining several weakly...
The Location-based service scheme have already involved in every aspect of People's daily life and are increasingly used various industries. Aiming at the problem security efficiency mobile terminal users’ trajectory privacy protection location-based service, we propose a k-anonymous based on differential privacy. This adopts technology to add Laplace noise user's many times generate 2k trajectory, then according similarity determine k-1 users whose similar user sets them real as an...
There are different kinematics and static stiffness characteristics for structure parameters of the same type Parallel mechanism. So reasonable design becomes a key problem parallel mechanism design. In this paper, parameter optimization method 3-UPU is proposed based on comprehensive dexterity. First, position mathematical model derived Jacobi matrix established. By two methods (the condition number evaluation dexterity evaluation), proposed. Through analysis, latter superior to former. The...
