Current Spectrum(当前频谱)研究综述
Current Spectrum 当前频谱 - Objective: To investigate the current spectrum of cannabis-based product use through a patient survey at the University of British Columbia (UBC) Multiple Sclerosis (MS) Clinic. [1] Analysis of the spectrum allowed for the assignment of the trans conformer, but the gauche proved to be prohibitive, although it is believed to be present in the current spectrum. [2] A photocurrent spectrum of the ZnO UV sensor showed a peak at wavelength of about 370 nm, and the sensor did not show a response in wavelengths of the visible light region. [3] To establish whether diagnostic services target geographically important pathogens, there is a need to know the current spectrum of etiology. [4] OBJECTIVE To review the current spectrum, potential strategies, and implementation process of telemedicine in pediatric surgery. [5] In order to extract the information from the current spectrum and the object-oriented method, it is impossible to integrate the spectral domain and the space domain to explore the feasibility of the frequency domain processing method to improve the recognition accuracy. [6] This article reviews the current spectrum of HIV-associated skin conditions, focusing on common complaints, infections, drugassociated toxicity and malignancies based on recently published literature relevant to this area. [7] OBJECTIVES In this study, the authors reviewed their experience of pediatric PFUIs and discussed the current spectrum of potential management options. [8] Thus, it is proposed in this paper, that the fault characteristic frequencies of roller bearings are identified in the current spectrum with the aid of envelope analysis on the bearing vibration signal. [9] With an increased number of clinicians adopting the use of BTX in the management of temporomandibular disorders (TMD) and/or bruxism, as either a standalone treatment or as an adjunct, affirmation is required in regards to whether it has a clinically justifiable position among the current spectrum of available treatment modalities. [10] For finite-control-set model predictive control with long horizons, a method is proposed that allows targeted harmonics in the current spectrum to be suppressed. [11] For a contrast device without a grating coupler, no SPHP-related signature is found in the photocurrent spectrum, because the incident radiation from free space cannot excite the SPHP, due to the mismatch of momentum. [12] Spectrums of the external flux for induction machines are rich in harmonics and they are not quite the same as current spectrum. [13] In this brief review, we will discuss the current spectrum of clinical applications of synovial biopsy in routine rheumatologic care and will provide an analysis of the perspectives for its potential exploitation in patients with chronic inflammatory arthritides. [14] These demands are directly driven by the consumer’s expectations, application requirements, and saturation of frequency bands used in current spectrum. [15] Thus ReBaHFC offers a new time-quality trade-off in the current spectrum of hypergraph partitioners. [16]目的：通过在不列颠哥伦比亚大学 (UBC) 多发性硬化症 (MS) 诊所进行的患者调查，调查大麻产品的当前使用范围。 [1] 对光谱的分析允许分配反式构象，但事实证明，gauche 是令人望而却步的，尽管它被认为存在于当前光谱中。 [2] ZnO UV 传感器的光电流光谱在约 370 nm 的波长处显示出峰值，并且传感器在可见光区域的波长上没有显示出响应。 [3] 为了确定诊断服务是否针对地理上重要的病原体，需要了解当前的病因谱。 [4] 客观的 回顾儿科手术中远程医疗的当前范围、潜在策略和实施过程。 [5] 为了从当前频谱中提取信息，面向对象的方法无法将频谱域和空间域结合起来，探索频域处理方法提高识别精度的可行性。 [6] 本文回顾了当前与 HIV 相关的皮肤病谱，根据最近发表的与该领域相关的文献，重点关注常见的主诉、感染、药物相关毒性和恶性肿瘤。 [7] 目标 在这项研究中，作者回顾了他们在儿科 PFUI 方面的经验，并讨论了当前的潜在管理选择范围。 [8] 因此，本文提出通过对轴承振动信号进行包络分析，在当前频谱中识别滚动轴承的故障特征频率。 [9] 随着越来越多的临床医生采用 BTX 治疗颞下颌关节紊乱症 (TMD) 和/或磨牙症，作为独立治疗或辅助治疗，需要确认它在临床上是否具有合理的地位当前可用治疗方式的范围。 [10] 对于具有长范围的有限控制集模型预测控制，提出了一种方法，可以抑制电流频谱中的目标谐波。 [11] 对于没有光栅耦合器的对比装置，在光电流光谱中没有发现与 SPHP 相关的特征，因为来自自由空间的入射辐射由于动量的不匹配而不能激发 SPHP。 [12] 感应电机的外磁通频谱含有丰富的谐波，与电流频谱并不完全相同。 [13] 在这篇简短的综述中，我们将讨论滑膜活检在常规风湿病治疗中的当前临床应用范围，并将分析其在慢性炎症性关节炎患者中的潜在利用前景。 [14] 这些需求是由消费者的期望、应用需求和当前频谱中使用的频段饱和度直接驱动的。 [15] 因此，ReBaHFC 在当前的超图分区器范围内提供了新的时间质量权衡。 [16]
Stator Current Spectrum 定子电流谱
Hence, stator current spectrum of healthy and faulty machines is studied. [1] Starting from field calculations and analyzing various cases of eccentricity, the methodology for determining the indicators for evaluation from the stator current spectrum is shown. [2] The results show the level of EF affects the sideband peak values significantly in the stator current spectrum. [3] The stator current spectrum is studied as fault identification mean and it is shown that the fault signatures depend on the number of total demagnetized magnets, the relative position of the magnets on the rotor and the stator winding topology. [4] The causes of various harmonics in the stator current spectrum are first investigated for better understanding. [5] Many harmonic types are exists in the stator current spectrum in healthy or in faulty IMs. [6] The novelty of the paper is that the Vs spectrum has not been used previously for fault identification in AFPM machines, as well as the stator current spectrum has not been analyzed before for a double-sided rotor, coreless stator topology with static axis eccentricity fault. [7] This chapter presents a summary of the most frequent faults and its consequences on the stator current spectrum of an IM. [8]因此，研究了健康和故障机器的定子电流谱。 [1] 从现场计算和分析各种偏心情况开始，给出了从定子电流谱中确定评估指标的方法。 [2] 结果表明，EF 水平显着影响定子电流谱中的边带峰值。 [3] 定子电流谱被研究为故障识别平均值，结果表明故障特征取决于总退磁磁体的数量、磁体在转子上的相对位置和定子绕组拓扑。 [4] 为了更好地理解，首先研究了定子电流频谱中各种谐波的原因。 [5] 在正常或故障 IM 的定子电流频谱中存在许多谐波类型。 [6] 这篇论文的新颖之处在于，Vs 谱以前没有用于 AFPM 机器的故障识别，而且以前没有分析过具有静态轴偏心故障的双面转子、无铁芯定子拓扑的定子电流谱。 [7] nan [8]
Grid Current Spectrum
The main idea is reducing the amplitude of high-switching harmonic, which introduces a significant part to the grid current spectrum. [1] Offline computed optimal pulse patterns (OPPs) facilitate the shaping of the grid current spectrum at such low switching frequencies. [2] The simulation results showed that the MPC controller had the best performance for earth leakage current, total harmonic distortion (THD), and the grid current spectrum. [3]主要思想是降低高开关谐波的幅度，这在电网电流频谱中引入了重要部分。 [1] 离线计算的最佳脉冲模式 (OPP) 有助于在如此低的开关频率下对电网电流频谱进行整形。 [2] 仿真结果表明，MPC控制器对漏电电流、总谐波失真（THD）和电网电流频谱的性能最好。 [3]
Sequence Current Spectrum
The various contact methods are zero sequence current spectrum measurement, non-uniform time resampling of current, motor current spectrum analysis, vibration measurement, etc. [1] The method firstly smoothes the transient zero-sequence current spectrum of each feeder, and then performs EWT decomposition to extract the natural modal function that best characterizes the original signal, and obtains the energy peak and the intrinsic modal energy value to determine the probability of each line fault, respectively. [2]各种接触方法有零序电流谱测量、电流非均匀时间重采样、电机电流谱分析、振动测量等。 [1] 该方法首先对各馈线的暂态零序电流谱进行平滑，然后进行EWT分解，提取出最能表征原始信号的自然模态函数，得到能量峰值和固有模态能量值，确定各馈线的概率。线路故障，分别。 [2]
Motor Current Spectrum
Many faults exhibit specific fault frequencies in the motor current spectrum, which allows for fault detection. [1] Many of these faults induce specific frequency components in the motor current spectrum and can thus be used for fault detection and classification. [2]许多故障在电机电流谱中表现出特定的故障频率，从而可以进行故障检测。 [1] 其中许多故障会在电机电流频谱中产生特定的频率分量，因此可用于故障检测和分类。 [2]
current spectrum sharing
The analysis is based on stochastic geometry and combines opportunistic with concurrent spectrum sharing. [1] The current spectrum sharing systems are mainly based on propagation modeling. [2] Multiuser multiple-input multiple-output (MU-MIMO) cognitive radio (CR) systems can achieve higher spectral efficiency by multiplexing multiple users on the same time-frequency resources and allowing concurrent spectrum sharing instead of opportunistic sharing. [3]该分析基于随机几何并将机会主义与并发频谱共享相结合。 [1] 当前的频谱共享系统主要基于传播建模。 [2] 多用户多输入多输出 (MU-MIMO) 认知无线电 (CR) 系统可以通过在相同时频资源上复用多个用户并允许并发频谱共享而不是机会共享来实现更高的频谱效率。 [3]
current spectrum acces
This paper is concerned with a machine learning approach to cancel the interference for cognitive Internet of Things (C-IoT) in the concurrent spectrum access (CSA) model, where the C-IoT system is noncooperative and has very limited knowledge on the interference. [1] The mainstay of current spectrum access grants exclusive rights to proprietary occupants who exhibit tidal traffic patterns, leading to low usage of valuable spectrum resources. [2] In addition, current spectrum access techniques are also unable to detect network changes or even consider the requirements of unlicensed users, leading to a poorer quality of service (QoS) and excessive latency. [3]本文关注的是一种机器学习方法来消除并发频谱接入 (CSA) 模型中认知物联网 (C-IoT) 的干扰，其中 C-IoT 系统是不合作的并且对干扰的了解非常有限。 [1] 当前频谱访问的主体授予具有潮汐流量模式的专有占用者专有权利，导致宝贵频谱资源的使用率低。 [2] nan [3]
current spectrum analysi
Fault detection using current spectrum analysis is attracting an increasing interest as a condition-based monitoring (CBM) technique. [1] Current spectrum analysis is mainly employed to detect the anomaly. [2] Detection of PMSM rotor asymmetry currently relies on offline testing and online vibration/current spectrum analysis. [3]使用电流频谱分析的故障检测作为基于状态的监测 (CBM) 技术引起了越来越多的关注。 [1] 目前的频谱分析主要用于检测异常。 [2] PMSM转子不对称性的检测目前依赖于离线测试和在线振动/电流谱分析。 [3]
current spectrum show
The current spectrum shows that the third harmonic current accounts for the majority of the harmonics. [1] The photocurrent spectrum shows that the peak photocurrent intensity of grating coupled QWIP is about 16 times higher than that of nongrating QWIP. [2]电流谱显示三次谐波电流占谐波的大部分。 [1] 光电流谱表明，光栅耦合QWIP的峰值光电流强度约为非光栅QWIP的16倍。 [2]
current spectrum measurement
The various contact methods are zero sequence current spectrum measurement, non-uniform time resampling of current, motor current spectrum analysis, vibration measurement, etc. [1] X-ray photoelectron spectroscopy(XPS), UV–vis diffuse reflectance spectroscopy (DRS), photoluminescence spectra(PL) and Photocurrent spectrum measurement were applied to quantitatively characterize the bonding between TiO2 and rGO, the band gap energy of catalysts as well as electron–hole pairs recombination rate. [2]各种接触方法有零序电流谱测量、电流非均匀时间重采样、电机电流谱分析、振动测量等。 [1] 应用X射线光电子能谱(XPS)、紫外-可见漫反射光谱(DRS)、光致发光光谱(PL)和光电流光谱测量来定量表征TiO2和rGO之间的键合、催化剂的带隙能以及电子–空穴对复合率。 [2]
current spectrum condition
For this reason, wireless devices will need to continuously adapt to current spectrum conditions by changing their communication parameters in real-time. [1] The proposed mechanism analyzes the arriving traffic requirement as well as the current spectrum condition, and then takes the effectiveness and the complexity of spectrum defragmentation into consideration simultaneously. [2]出于这个原因，无线设备将需要通过实时更改其通信参数来不断适应当前的频谱条件。 [1] 该机制分析了到达的业务需求以及当前的频谱状况，然后同时考虑了频谱碎片整理的有效性和复杂性。 [2]
current spectrum allocation
To improve the efficiency of the current spectrum allocation, dynamic spectrum sharing is being considered by regulators in several jurisdictions. [1] As the number of wireless devices explodes in the lead up to the release of 5G communications technology, it is expected that the demands for usage of the wireless spectrum will increase to the point where current spectrum allocation methods will no longer be sufficient. [2]为了提高当前频谱分配的效率，多个司法管辖区的监管机构正在考虑动态频谱共享。 [1] 随着 5G 通信技术的发布，无线设备的数量激增，预计对无线频谱的使用需求将增加到当前频谱分配方法不再足够的程度。 [2]
