In this paper we present a higher order moment-matching algorithm for computing the distribution parameters of nonlinear transformation random variables. The new algorithm has two distinct aspects compared to the standard Unscented Kalman Filter (UKF). First, the sigma points are computed in two steps using the covariance matrix and higher-order moments. Second, the associated weights are positive...
According to the solution to transcendental equation for selective harmonic elimination inverter is difficult,a method of solution to switching angles based on the rapid expansion of cos(nα) was presented. The SHET transcendental equation has been simplified by the law of rapid expansion of cos(nα).This method enlarges the range of initial switching angles and there is no divergence or singular value...
Researching on cavitation of propeller which is an important part of ship bubble wake has important signification for studying ship bubble wake. The three viscous flow field of a five-blade high-skew propeller was simulated with numerical method. Based on RANS method, SST turbulent model and Single full cavitation model were used to simulate and analyze the cavitation characteristics of the propeller...
In clinical diagnosis, a grade indicating the severity of nuclear cataract is often manually assigned by a trained ophthalmologist to a patient after comparing the lens' opacity severity in his/her slit-lamp images with a set of standard photos. This grading scheme is often subjective and time-consuming. In this paper, a novel computer-aided diagnosis method via ranking is proposed to facilitate nuclear...
State-of-the-art deformable registration algorithms do not perform as well with FA sequences because they are designed to deal with changes of content appearance (e.g., due to different sensors imaging the same organs) but not with content changes, which occur throughout a FA sequence as different portions or the vascular structure are visible (perfused) in different frames. This paper presents a...
The paper describes a low complexity tree-structure based user scheduling algorithm in a MLD-based multi-user multiple-input multiple-output (MIMO) wireless systems. An M-branch selection algorithm, which selects M most-possible best branches at each step, is proposed to maximize the whole system sum-rate capacity. To make this work more feasible, some implementation problems such as complexity reduction,...
