The triple jump is one of two track and field events in which the athlete aims to maximize the horizontal distance jumped. This jump is comprised of 3 take-off phases (hop, step, and jump), each playing an important role, as they require the jumper to tolerate extremely high forces of impact and to maintain a high level of horizontal velocity. The purpose of the study was to investigate the bio...

We present a new algorithm to perform blind signal separation (BSS), which takes a trade-off between the ordinary gradient infomax algorithm and the natural gradient infomax algorithm. Analyzing the algorithm, we show that desired equilibrium points are locally stable by choosing appropriate score functions and step sizes. The algorithm provides better performance than the ordinary gradient alg...

Virtual worlds exploration techniques are used in a wide variety of domains — from graph drawing to robot motion. This paper is dedicated to virtual world exploration techniques which have to help a human being to understand a 3D scene. An improved method of a viewpoint quality estimation is presented in the paper, together with a new method for an automatic 3D scene exploration, based on a vir...

In this article, an implicit hybrid method of order six is developed for the direct solution of second order ordinary differential equations using collocation and interpolation approach. To derive this method, the approximate solution power series is interpolated at the first and off-step points and its second and third derivatives are collocated at all points in the given interval. Besides hav...

We propose a new algorithm for automatic viewpoint selection for volume data sets. While most previous algorithms depend on information theoretic frameworks, our algorithm solely focuses on the data itself without off-line rendering steps, and finds a view direction which shows the data set’s features well. The algorithm consists of two main steps: feature selection and viewpoint selection. The...

BACKGROUND Because of concerns about the safety of long-acting β(2)-agonist (LABA) use in patients with asthma, withdrawal of the LABA is recommended by the US Food and Drug Administration once asthma is controlled by combination therapy with a LABA and inhaled corticosteroid (ICS). OBJECTIVE To perform a systematic review and meta-analysis assessing evidence supporting the discontinuation of...
