There is no line of demarcation between the shoulder and elbow regions. Pain In the arm may originate at the shoulder with reference downwards or less often at the elbow with reference upwards. Most pains indicated by the patient at the elbow or forearm have a local origin, since at the more distal part of the upper limb the capacity for correct localization is good. Once it is clear that the elbow region is at fault, the joint and the muscles about it are tested by ten movements. 1. Four. Passive extension, flexion, pronation, supination-full range, LOM, painful, painless. 2. Four. Resisted extension, flexion, pronation, supination-strong, weak, painful, painless. 3. Two. Resisted flexion, extension at the wrist-painful, painless. The muscles that perform theses two movements arise from the humeral epicondyles and a lesion in either often causes pain felt at the elbow although the tissuse affected is not functionally a part of the elbow (i. e. Tennis elbow and Golfer's elbow).

본 논문에서는 깊이맵 업샘플링을 이용하여 객관적 메트릭과 3D 주관적 평가 사이의 관계를 조사한다. 전자의 경우, 다양한 참조(full-reference) 및 무참조(no-reference) 평가도구가 깊이맵의 품질을 측정하기위해 적용되고, 3D평가는 주관적 평가로 얻는다. 이 두 개의 결과는 세 가지의 상관계수를 이용하여 상호 관련성을 찾은 후에, 최적으로 주관평가에 근접한 객관적 메트릭을 얻는다.

Is the history of surgery an independent field of research into Chinese medicine? The historical sources are fragmentary, scattered, and riddled with fantastical descriptions. To unlock the references made in sixteenth-century texts to the use of silk thread to stitch up damaged tracheas, which are taken to be factual, the author of this article proposes a research method he calls "investigating precedents." Every independent reference to this kind of surgery must be dealt with separately. We cannot assume, a priori, that a reference to what must have been a very sophisticated procedure is either a far-fetched interpretation or a fabrication, nor should we evaluate it according to modern surgical criteria. Apart from extraordinary cases, we have no records of other types of surgery in the history of Chinese medicine, therefore we must find a method that allows us to investigate these records on their own terms.

This paper proposes a high speed systolic array architecture for full search block matching algorithm (FBMA). The pixels of the search area for a reference block are input only one time to find the matched candidate block and reused to compute the sum of absolute difference (SAD) for the adjacent candidate blocks. Each row of designed 2-dimensional systolic array compares the reference block with the adjacent blocks of the same row in search area. The lower rows of the designed array get the pixels from the upper row and compute the SAD with reusing the overlapped pixels of the candidate blocks within same column of the search area. This designed array has no data broadcasting and global paths. The comparison with existing architectures shows that this array is superior in terms of throughput through it requires a little more hardware.

In this paper, a novel control scheme compensating for source voltage unbalance and current harmonics and power factor correction in unified active power filter systems combined with shunt passive filters is proposed, where no low/high-pass filter are used in deriving the reference voltage for compensation. Using digital all-pass filters, the phase angle and the reference voltages compensating for harmonic current and unbalanced voltage are derived from the positive sequence component of the unbalanced voltage. The amplitude of d-axis current in a series filter is controlled as zero for power factor correction. The validity of the proposed control scheme has been verified by experimental results.

A DC current sensor is disclosed in which two pairs of saturable cores are provided so as enclose a conductor carrying a direct current to be measured. On each of the saturable cores, a bias winding, a feedback winding and an output winding are wound. Circuit for detection of an asymmetry in the magnetization current, generated by a reference alternating voltage, in a signal-conditioner. The reference alternating voltage is fed to the respective series circuits such that no resultant induction current is induced in the modulating current. The voltages over the resistor form input signals for two peak value detectors, the strength of the output signal of which represents the degree of asymmetry of magnetization current. This paper describes the development a DC current sensor and its signal-conditioner.

A high speed Analog parallel processing-based Viterbi decoder with a circularly connected 2D analog processing cell array is proposed. It has a 2D parallel processing structure in which an analog processing cell is placed at each node of trellis diagram is connected circulary so that infinitively expanding trellis diagram is realized with the fixed size of circuits. The proposed Viterbi decoder has advantages in that it is operated with better performance of error corrections, has a shorter latency and requires no path memories. In this parer, the performance of error correction as a reference position with the Analog parallel processing-based Viterbi decoder is testd via the software simulation

The computed-torque method (CTM) shows good trajectory tracking performance in controlling robot manipulator if there is no disturbance or modelling errors. But with the increase of a payload or the disturbance of a manipulator, the tracking errors become large. So there have been many researches to reduce the tracking error. In this paper, we propose a new control algorithm based on the CTM that decreases a tracking error by generating new reference trajectory to the controller. In this algorithm we used the concept of sliding mode theory and fuzzy system to reduce chattering in control input. For the numerical simulation, we used a 2-link robot manipulator. To simulate the disturbance due to a modelling uncertainty, we added errors to each elements of the inertia matrix and the nonlinear terms and assumed a payload to the end-effector. In this simulation, proposed method showed better trajectory tracking performance compared with the CTM.

In this paper, a new adaptive control scheme is proposed that uses a special form of rational function-type linear operator in the parameter adaptation and that removes the augmenting signal terms of the control input components. This adaptation scheme is applied to the MRAC of continuous-time, linear time-invariant, minimum-phase plants whose relative degrees are arbitrary. This scheme can be applied without any change of the controller structure to the adaptive systems regardless of the relative degree if it is greater than 1. And this scheme does not require any signal augmentation for arbitrary relative-degree plants if the reference model has no zeros. The asymptotic stability of the adaptive systems controlled by this scheme is shown by a hyper-stability method.

The purpose of this study is to identify torque characteristics in capacitor type electric motors and to illustrate the effects of several design parameters on the fluctuating components of the motor torque. To do this, two revolving field theory and stationary reference frame theory were applied to derive governing equations for the torque generated by motor. For simulation studies, parameters of the motor components were measured under the conditions of no loading and locking. Based on these, effects of several design variables on the torque characteristics were analyzed and compared with the actual measurements, which were estimated indirectly by measuring the stator voltage and current. Then, some illustrative improvements in design are suggested by taking Taguchi method.
