Purpose Rapid satellite capture by a free-floating space robot is a challenge problem because of no-fixed base and time-delay issues. This paper aims to present a modified target capturing control scheme for improving the control performance. Design/methodology/approach For handling such control...

Measurement error occurs in many biomedical fields. The challenges arise when errors are heteroscedastic since we literally have only one observation for each error distribution. This paper concerns the estimation of smooth distribution function when data are contaminated with heteroscedastic...

Purpose – The purpose of this paper is to analyze the prices and consumer behavior at Woot.com, a deep discount online retailer, and compare two selling mechanisms it uses – the regular “one deal a day” and the “woot‐off” mechanisms. The paper also compares the “one deal a day”...

We introduce the concept of an extremely negatively dependent (END) sequence of random variables with a given common marginal distribution. An END sequence has a partial sum which, subtracted by its mean, does not diverge as the number of random variables goes to infinity. We show that an END...

Purpose This paper aims to address the following issues: (1) most existing methods are based on recurrent network, which is time-consuming to train long sequences due to not allowing for full parallelism; (2) personalized preference generally are not considered reasonably; (3) existing methods...

In all kinds of modern fountains, music fountain can integrate human's sense of vision and hearing in real time, and plan the perfect environmental art effect in the urban planning landscape. Based on this, the theory of musical feature recognition was proposed, and the forms of the fountain and...
