Computational studies provide support for the involvement of intermolecular pi-interactions in chiral recognition secondary benzylic alcohols by enantioselective acyl transfer catalyst CF3-PIP.
This study examines how the prevalence of depression and anxiety symptoms differ by socioeconomic status explores their associations with diabetes in rural southwest China. Data were collected from a cross-sectional health interview examination survey 5,005 adults aged ≥ 35 years Height, weight, waist circumference, fasting blood glucose measurement taken. Depression assessed using Zung's Self-rating Scale (SDS) Self-Rating Anxiety (SAS), respectively. An individual position (SEP) index was...
Keyword Spotting (KWS) plays a vital role in human-computer interaction for smart on-device terminals and service robots.It remains challenging to achieve the trade-off between small footprint high accuracy KWS task.In this paper, we explore application of multi-scale temporal modeling smallfootprint keyword spotting task.We propose multi-branch convolution module (MTConv), CNN block consisting multiple filters with different kernel sizes, which enriches feature space.Besides, taking...
As a classic algorithm for realizing robot local path planning, the dynamic window approach (DWA) uses an objective function to choose optimal velocity commands. However, generated by DWA in complex environment is not smooth. Therefore, this paper proposes improved make of more smoother when avoiding obstacles. At same time, view condition that weight coefficients evaluation original remain unchanged, will add fuzzy controller realize adaptation, so as adapt environment, and can be smoother.
This article proposes a cognitive frequency diversity array (FDA) multiple-input multiple-output (MIMO) (FDA-MIMO) radar network (CFDA-MIMON) target discrimination and tracking algorithm under main-lobe deceptive trajectory interference. can be divided into two stages: search-discrimination-initialization tracking. The first stage mainly uses the distribution characteristics of interference on different radars to discriminate in network. A state initialization strategy driven by G-pair...
In this article, we investigate the problem of target localization with a multiple-input–multiple-output (MIMO) and frequency diverse array MIMO (FDA-MIMO) dual-mode radar system. The signal model for newly introduced system is presented in detail. On basis, computationally efficient method joint angle range estimation proposed by taking advantage subspace principle. First, direction-of-arrival (DOA) each determined utilizing fused data received via radar. order to solve coupling...
Range ambiguity is common for estimating range with the multiple-input and multiple-out (MIMO) radar employing elevated pulse repetition frequency (PRF). Despite that diverse array (FDA) or element-pulse coding (EPC) in transmitter provides possibility resolving at a single PRF, involved orthogonal waveform sequences are unpractical pulse-Doppler radars. In this paper, MIMO-based hybrid of FDA EPC investigated to mitigate enhance resolution, which so called EPC-FDA-MIMO. Employing ampliative...
This paper proposes an unambiguous method for joint angle and range estimation in colocated multiple-input multiple-output (MIMO) radar using the nested frequency diverse array (NFDA). Unlike a conventional phased (PA), transmission beampattern of FDA-MIMO depends not only on but also range, which enables precise identification ambiguous regions two-dimensional space. As result, we can simultaneously estimate targets radar, even when ambiguity exists. By employing configuration, degrees...
This paper investigates a multi-antenna, multi-input multi-output (MIMO) dual-functional radar and communication (DFRC) system platform. The simultaneously detects targets communicates with downlink cellular users. However, the modulated information within transmitted waveforms may be susceptible to eavesdropping. To ensure security of transmission, we introduce non-orthogonal multiple access (NOMA) technology enhance performance MIMO-DFRC Initially, consider scenario where channel state...
This article is focused on resolving the problem of suppressing mainbeam deceptive jammers in element-pulse coding (EPC) radar. At modeling stage, phase matrix (EPPCM) employed at transmit side, introducing extra degrees-of-freedom (DOFs) for discrimination true target and jammers. By utilizing DOFs, nonadaptive adaptive suppression method are developed. Firstly, order to suppress non-adaptively, EPPCM designed based steering vector orthogonalization (CSVO) method, which requires identical...
Traditional Text-Dependent Speaker Recognition (TDSR) systems model the user-specific spoken passwords with frame-based features such as mel frequency cepstral coefficient (MFCC) and use Dynamic Time Warping (DTW) or hidden Markov Model (HMM) classifiers to handle variable length of feature vector sequence. However, DTW can't deal cross-channel issue while HMM needs more computational complexity storage space. In this paper, we introduce text-independent framework GMM-UBM into text-dependent...
