With the great concerns on alleviating the pollution on the environment and traffic congestions; there is a trend for developing the electric vehicles [1], [2]. For such drive system, the in-wheel machines draw the main attention due to its relative higher torque density and compact structure [1]. With the permanent magnet (PM) located on the stator teeth, the flux switching permanent magnet machine...
In the last decades the electrical stimulation therapy has played an important role for neural regeneration. However, the amplitude of electric shocks will be decayed greatly after penetrating into biological tissues. The patient will also suffer from the skin injury caused by electrodes. Recent years, the positive effect of magnetic stimulation on neuronal growth has been studied for several years...
The interface magnetic phenomenon, which forms the backbone of modern information technology, is of great interest for several decades. When two or more dissimilar materials with different long-range magnetic orderings and/or functionalities are combined together, it may give rise to new interfacial properties, such as the proximity effect [1]. The exchange coupling between two FM layers, as well...
The recent rise of mobile applications such as Internet of Things (IoT), wearable electronics, and context aware computing has renewed the search for a universal embedded memory technology [1]. Such a technology should combine fast read/write, low voltage operation, low power consumption, non-volatility, infinite endurance, with CMOS process compatibility. Magnetic Random Access Memory based on Spin...
High temperature superconducting (HTS) cables for large current transmission in general have a multilayer structure consisting of parallel connected tapes, twisted in each layer. The control of current distribution among these layers is an important issue for design and optimization of a HTS cable because this would significantly affect the current transmission capacity and power losses. The pinned...
We propose a machine learning-based method to automatically detect flow diverters in cerebral C-arm CT images. An appearance detector is learned to generate hypotheses of a flow diverter's location in a volumetric image. A probabilistic framework incorporating a local appearance and shape model is developed to trace the flow diverter. Promising results have been obtained on clinical data. The proposed...
Moving seawater through geomagnetic field can evoke a distribution of weak electric currents in the medium, which may generate a measurable magnetic field. The velocity vector of moving seawater can be resolved by using the ship wave theory, and the induced magnetic field can be evaluated by solving the Maxwell equations. Simulation results show that the induced magnetic field by the wake of a typical...
This paper explores a way to promote the maximum capacity of distributed generations (DGs) that a distributed network could consume through network reconfiguration. The reconfiguration model considering wind power and photovoltaic is established and an improved particle swarm optimization (PSO) algorithm based on statistics is proposed to solve the problem. The algorithm is improved by introducing...
Magnetic logic has recently become an attractive candidate for future electronics. This paper describes the demonstration of a four-terminal spintronic device with distinct read- and write-paths (“mCell”). The mCell enables a non-volatile circuit technology (mLogic) with gain sufficient to drive fanout independent of CMOS [1]. Measured material properties and prototype device results are presented.
This paper presents a novel method of multiresolution morphological gradient (MMG), which uses trapezoid structuring elements (SE), for the identification of power disturbances. MMG is a nonlinear morphological transform which presents the gradient information in the output. Another simple morphological operator, closing operator which can extract envelopes of signals, is also applied in combination...
There is increasing demand of advanced TEM techniques for modern IC failure analysis. Some practical issues of using TEM holography in studying MOSFETs P-N junction, channel strain and magnetic domains are discussed in this paper. It is shown that salicide/contact have significant effect on the phase diagram of shallow S/D P-N junction and hinders its application in shallow junction devices. In holography...

In this work, TEM dark-filed off-axis holography using objective lens was investigated to study strain distribution in Fin structure induced by stress liner. Compared with Lorentz lens mode holography, objective lens holography provides much more improved spatial resolution and contrast which are critical for reliable strain measurement of small structures such as FinFETs. Result was also compared...
This paper presents an aptamer-based microchip for sensitive and quantitative detection of biomolecules using matrix-assisted laser desorption/ ionization time-of-flight mass spectrometry (MALDI-TOF MS). The device is capable of both isolating analyte from samples and dispensing purified samples onto a probe plate for a following MS analysis. Aptamers selectively captured and released target molecules...
This paper explains how the method of system identification can be applied to a quadrotor helicopter. First the first principles model is studied. The open-loop model is an unstable system, which is simulated using a closed-loop scheme. Then, a 12th order Auto Regressive Moving Average with eXogenous inputs (ARMAX) model is obtained based on the simulation data.
