It is well-known that many robust stability and performance problems in control lead to computing the structured singular values of some closed-loop system transfer matrices. The standard definition of structured singular value assumes that the uncertainties are only norm bounded. However, in many applications, the uncertainties involved are constrained, for example, the uncertain parameters ar...

A new kind of linear model with partially variant coefficients is proposed and a series of iterative algorithms are introduced and verified. The new generalized linear model includes the ordinary linear regression model as a special case. The iterative algorithms efficiently overcome some difficulties in computation with multidimensional inputs and incessantly appending parameters. An important...

This paper contains investigations on the behavior of five artificial rocklike materials subjected to abrasive water jet cutting. The influence of the test parameters, i.e. applied pump pressure, traverse rate and abrasive mass flow rate was investigated, as well as the influence of several material parameters, e.g. compressive strength, Young's modulus, absorbed fracture energy and crack veloc...

This paper proposed a new method to analyze the human walking by using a 3-wheels rollator walker instrumented with encoders and a 3D accelerometer/gyrometer. In order to develop the walking quality index and monitor the health state of elderly people at home, the walking of 23 young adults and 25 elderly people (> 69 years) with the help of the walker, are compared. Besides of the comparison o...

In order to distinguish dysfunctional gait, clinicians require a measure of reference gait parameters for each population. This study provided normative values for widely used parameters in more than 1,400 able-bodied adults over the age of 65. We also measured the foot clearance parameters (i.e., height of the foot above ground during swing phase) that are crucial to understand the complex rel...

This paper studies estimation of partially linear hazard regression models with varying coefficients for multivariate survival data. A profile pseudo-partial likelihood estimation method is proposed. The estimation of the parameters of the linear part is accomplished via maximization of the profile pseudo-partial likelihood, while the varying-coefficient functions are considered as nuisance par...

We construct a set of order parameters for non-Abelian gauge theories which probe directly the unbroken group and are free of the deficiencies caused by quantum fluctuations and gauge fixing which have plagued all previous attempts. These operators can be used to map out the phase diagram of a non-Abelian gauge theory. PACS numbers:11.15.-q,03.65.Bz,03.80.+r Typeset using REVTEX

This paper describes how the most complete recent linguistic results on Korean scrambling (switching of word order) can be readily incorporated into an existing principlesand-parameters parser with minimal additional machinery. Out of all 29 sets of examples in chapters 2.2 and 3.2 of perhaps the most advanced linguistic analysis of Korean scrambling, [5]. 6 sets of examples can be correctly pa...

Motivated by applications to goodness of fit testing, the empirical likelihood approach is generalized to allow for the number of constraints to grow with the sample size and for the constraints to use estimated criteria functions. The latter is needed to handle naturally occurring nuisance parameters. A central limit theorem is proved to deal with quadratic forms based on random vectors of inc...

We present two-dimensional filter banks with directional vanishing moments. The directional-vanishing-moment condition is crucial for the regularity of directional filter banks. However, it is a challenging task to design orthogonal filter banks with directional vanishing moments. Due to the lack of multidimensional factorization theorems, traditional one-dimensional methods cannot be extended ...
