In High Speed Downlink Packet Access (HSDPA), the majority of results assumes that perfect channel estimation is available and does not consider a suitable method of channel estimation or its effect on system performance. In this paper, we present a channel estimation based on a simple pilot scheme with space time rake receiver taking into account the speed of User Equipment (UE) in HARQ contex...
This paper presents linear estimation techniques used to identify the stator resistance, the stator leakage inductance (transient inductance), the stator self inductance and rotor time constant of an induction motor with measuring its speed. Such estimation is important in the determination of the achieve performance for induction motor drives. The discrete-time parameter estimation models expr...
In diagnostic ultrasound imaging the speed of sound is assumed to be 1540 m/s in soft tissues. When the actual speed is different, the mismatch can lead to distortions in the acquired images, and so reduce their clinical value. Therefore, the estimation of the true speed has been pursued not only because it enables image correction but also as a way of tissue characterisation. In this paper, we...
A Modified Hardware-Efficient H.264/AVC Motion Estimation Using Adaptive Computation Aware Algorithm
In order to increase transmission efficiency of the real world video sequences, Motion estimation (2) plays an vital role. An improved version of the reconfigurable block motion estimation algorithm (3) is proposed in this paper. The new algorithm uses a small cross-shaped search patterns to speed up the motion estimation of stationary and quasistationary blocks. Also we propose a pipelining me...
In this study, we propose a novel markerless motion capture system (MCS) for monkeys, in which 3D surface images of monkeys were reconstructed by integrating data from four depth cameras, and a skeleton model of the monkey was fitted onto 3D images of monkeys in each frame of the video. To validate the MCS, first, estimated 3D positions of body parts were compared between the 3D MCS-assisted es...
metric (mapping evapotranspiration at high resolution with internalized calibration) is known as an appropriate surface energy balance model for the estimation of the spatial distribution of evapotranspiration (et) in semi-arid regions. based on lysimeter measurements, metric has shown et estimates of 10% on a sub-field scale on a daily basis. there is a need to identify how the model is sensit...
The permanent magnet synchronous motor is increasingly playing an important role in advanced motor drives. An encoder or resolver attached to the shaft of the motor typically supplies the feedbacks required for motor speed control. Many advanced motor drives cannot tolerate the use of these feedback devices because of reliability concerns in a harsh environment, price, space and weight limitati...
Smooth-pursuit eye velocity to a moving target is more accurate after an initial catch-up saccade than before, an enhancement that is poorly understood. We present an individual-differences-based method for identifying mechanisms underlying a physiological response and use it to test whether visual motion signals driving pursuit differ pre- and postsaccade. Correlating moment-to-moment measurem...
