The transport properties of nontrivial spin textures are coming under closer scrutiny as the amount experimental data and theoretical simulations is increasing. To extend commonly accepted yet simplifying approximate picture effects taking place in systems with spatially varying magnetization, it important to understand building blocks for textures---the homochiral spin-spiral states. In this w...

The objective of the paper is to develop a novel intelligent pitch control system of a 2MW wind turbine driven by variable-speed hydraulic pump-controlled system. For realizing the intelligent pitch controller, self-organizing fuzzy sliding mode control, which combines fuzzy sliding mode control and self-organizing modifier, is proposed. In order to verify the proposed concept experimentally, a...

Self-motion, steering, and obstacle avoidance during navigation in the real world require humans to travel along curved paths. Many perceptual models have been proposed that focus on heading, which specifies the direction of travel along straight paths, but not on path curvature, which humans accurately perceive and is critical to everyday locomotion. In primates, including humans, dorsal media...

We present an algorithm for tracking individual instruments in polyphonic music recordings. The algorithm takes as input the instrument identities of the recording and uses non-negative matrix factorisation to compute an instrument-independent pitch activation function. The Viterbi algorithm is applied to find the most likely path through a number of candidate instrument and pitch combinations ...

Chiral 3D photonic crystals are an interesting subclass of 3D photonic crystals. For example, large complete 3D photonic bandgaps have been predicted for high-index-contrast silicon square-spiral structures; corresponding experiments using glancing-incidence deposition, interference lithography, or direct laser writing have been published. In addition to complete gaps or stop bands, theory also...
