Hexacopter Pitch Estimator for a Pitch Stabilizer

IFAC Proceedings Volumes, 2013
Abstract The paper presents the development and mathematical modelling of an estimator within the control scheme of the pitch motion of a hexacopter. The pitch estimator is constructed as a classic Luenberger-Kalman filter. The authors also discuss the problem of acceleration measurement realized during the flight of the hexacopter.

Functionalized Lignin Derivatives as Melt‐Spinnable Precursors for Carbon Fiber Production without Stabilization

Advanced Functional Materials, EarlyView.
By turning off hydrogen bonds by bulky ethyl cinnamate ester derivatization, softwood kraft lignin can flow under elevated temperatures, providing tough fiber in the melt for high take‐up speed. Subsequently, lignin ethyl cinnamate derivatives are readily stabilized with only dilute nitric acid leading to direct carbonized fiber with outstanding ...

Investigating the variation of intonation contours in Northern Vietnamese tones

Frontiers in Education
Intonation is an instrument for structuring discourse and emphasizing different types of information. In German, for example, pitch is used to highlight focus, while in Vietnamese, different pitch contours distinguish lexical tones.

Development of Thick-foil and Fine-pitch GEMs with a Laser Etching Technique

, 2009
We have produced thick-foil and fine-pitch gas electron multipliers (GEMs) using a laser etching technique. To improve production yield we have employed a new material, Liquid Crystal Polymer, instead of polyimide as an insulator layer.

Dynamically Adaptive Wrinkle‐Structured Light‐Regulating Films for Energy‐Efficient Buildings

Advanced Functional Materials, EarlyView.
A scalable, moisture‐responsive cellulose nanofibril/polyvinyl alcohol (CNF/PVA)‐glycerol film with switchable wrinkled surfaces for dynamic light regulation is developed. Compared to glass, it achieves tunable light diffusion for daylight harvesting, thermal regulation, and privacy control.

Commentary on "The Influence of Pitch Height on the Perception of Submissiveness and Threat in Musical Passages" by David Huron, Daryl Kinney, and Kristin Precoda

Empirical Musicology Review, 2006
Increasingly, the Arts and Humanities and Science fields are finding common ground, as illustrated in Huron et al.’s fine paper. My commentary discusses the origin of the idea that pitch and motivation have an evolved relationship.

The pitch-heave dynamics of transportation vehicles [PDF]

, 1975
The analysis and design of suspensions for vehicles of finite length using pitch-heave models is presented. Dynamic models for the finite length vehicle include the spatial distribution of the guideway input disturbance over the vehicle length, as well ...
