As interturn short fault (ISF) in a permanent-magnet synchronous machine (PMSM) degrades its energy efficiency and may cause other problems, accurate diagnosis for the PMSMs is necessary. In this paper, we present method that uses voltage current residual components to diagnose phase severity of ISF PMSMs. A faulty-winding model (FWM) introduced analyze fault; describes relationship between decrease faulty winding characteristics such as resistance turn ratio. Based on model, suggest index...

We present a method that detects and classifies demagnetization interturn short faults (ISFs), which degrade the performance of permanent-magnet synchronous machines (PMSMs). Demagnetization ISF are analyzed using models; we focused on changes magnitude angle currents in frame. Those two increase input current compared with normal at same load torque. However, our analysis suggests causes β, whereas decrease β. exploit this difference response to classify fault if one is detected PMSM....

This paper reports our recent finding that a laser is radiated on thin light-absorbing elastic medium attached the skin can elicit tactile sensation of mechanical tap. Laser radiation to creates inner waves basis thermoelastic effects, which subsequently move and stimulate skin. We characterize associated stimulus by measuring its physical properties. In addition, perceptual identity confirmed comparing it electrical stimuli means spaces. All evidence claims indirect conveys short tap with...

Herein, the feasibility of gas tungsten arc welding‐based wire + additive manufacturing process for fabricating thin wall structures niobium‐1 wt% zirconium (NbZr1) alloy is investigated. Three different heat input conditions (low, medium, and high) have been selected it. The microstructure characterized by using optical microscopy, scanning electron X‐ray diffraction, energy‐dispersive spectroscopy, backscattered diffraction (EBSD). shows columnar dendritic structure elongated in build...

In this paper, we present an experimental study in which tested the feasibility of a hybrid haptic assistance scheme that combines guidance and disturbance. our method, is used initial phase learning, but it progressively turned into disturbance as learner's performance improves. The purpose to help learners become familiar with new motor skill more quickly easily, while use further improve learners' later stage training. order assess assistance, conducted human subjects experiment using...

With the growth of factory automation, deep learning-based methods have become popular diagnostic tools because they can extract features automatically and diagnose faults under various fault conditions. Among these methods, a novelty detection approach is useful if dataset imbalanced impossible reproduce perfectly in laboratory. This study proposes detection-based soft fault-diagnosis method for control cables using only currents flowing through cables. The proposed algorithm uses...

In this paper, we propose a method to diagnose an interturn short-circuit fault (ISCF) and demagnetization (DF) in interior permanent magnet synchronous machine (IPMSM) using 1-D convolutional neural network (1-D CNN). addition, the proposed detects even when two faults occur at same time. The CNN is used automatically extract features from raw signals use them detect classify faults. uses only three-phase current signals, so does not require additional sensors, which cost efficient....

This paper addresses a data-driven framework, modeling expert driving skills for performance-based haptic assistance using neural networks (NNs). We have built training simulator to collect data and provide proper feedback. establish an skill model by NNs with the collected data. Then, is applied optimized references of steering/pedaling movements. evaluate its application in two user experiments. The results first experiment demonstrate that our has appropriately captured experts' skills....

It is difficult to be aware of the personal context for providing a mobile recommendation, because each person's activities and preferences are ambiguous depend upon numerous unknown factors. In order solve this problem, we have focused on reality mining discover social relationships (e.g., family, friends, etc.) between people in real world. We assumed that any given person interrelated with those other people, investigated how take into account neighbor's contexts, which possibly an...

In this paper, we demonstrate that a laser irradiated on thin light-absorbing elastic medium attached the skin can elicit tactile sensation of mechanical tap. First, present simulation results show irradiation to creates inner waves basis thermoelastic effects and these trigger bending deformation medium, which then stimulates skin. Second, analyze physical properties associated stimulus by measuring its force profile. Third, identify perceptual characteristics in comparison those electrical...

This paper is concerned with the perceptual structure of homogeneous and deterministic haptic textures rendered by an electrovibration display. Textures were modeled using 32 regular tessellations polygons changing polygon, density, edge width, pixel intensity, image reversal. We conducted a experiment to estimate pairwise dissimilarities between cluster sorting procedure. then applied multi-dimensional scaling data obtained space that accounted for effects five design variables on texture...

Abstract The ER regulates the spatiotemporal organization of endolysosomal systems by membrane contact. In addition to tethering via heterotypic interactions on both organelles, we present a novel ER‐endosome mechanism mediated homotypic interactions. single‐pass transmembrane protein SCOTIN is detected in and endosomes. ‐knockout (KO) cells, ER‐late endosome contacts are reduced, perinuclear positioning endosomes disturbed. cytosolic proline‐rich domain (PRD) forms assemblies vitro...
