Fast pyrolysis of?pitch pine biomass?in a bubbling fluidized-bed reactor for bio-oil production
Pinus rigida pitch pine Thermogravimetric analysis Fast pyrolysis Bubbling fluidized-bed reactor Bio-oil
2023/12/18
The kinetic parameters for the pyrolysis of biomass of the pitch pine (Rigida pine?P. Mill) were examined by thermogravimetric analysis in the temperature range 25?°C to 700?°C, in which the main deco...
Wind turbine pitch optimization
Static trilobites horizontal axis wind turbine mechanical load
2015/8/7
We consider a static wind model for a three-bladed, horizontal-axis, pitch-controlled wind turbine. When placed in a wind field, the turbine experiences several mechanical loads, which generate power ...
Prairie Warbler Nest-site Selection, Nest Survival, and Demographic Response to Management in a Pitch Pine-Scrub Oak Barren
shrubland birds Setophaga discolor early-successional habitat shifting mosaic nest survival disturbance
2014/12/11
As shrubland bird populations decline, there is a critical need to understand the effects of habitat management. I studied a population of color-banded prairie warblers (Setophaga discolor) between 20...

FAST ACTING ROBUST CONTROLLER FOR PITCH CONTROL SYSTEM OF AIRCRAFT
characteristic ratios generalized time constant Butterworth polynomial
2010/1/11
In this paper a classical feedback controller has been designed to furnish
fast acting characteristics in the face of parametric perturbation using two
parameters, Generalized Time Constant and Char...
Speech Pre-Processing for Pitch and Pitch-Cylce Evolutions Smoothing
Pitch speech coder bit rate pitch cycle
2009/7/28
In low bit rate speech coders, pitch is usually transmitted once per frame and, when needed, the intermediate pitch values are obtained by interpolation between 2 adjacent pitch values. Although pitch...
Preparation of Mesophase Pitch and High Performance Carbon Fiber from Decant Oil
Decant oil Mesophase pitch Stabilization Preparation condition Carbon fiber
2009/7/24
The most efficient process and conditions for the preparation of mesophase pitch and carbon fiber from decant oil were examined. Mesophase pitch yield was extremely low (4.6%) when prepared directly b...
Variable Rotational Speed Control for Fixed-pitch Type Wind Turbines Using LPV Techniques
Rotational Speed Fixed-pitch Type LPV
2009/4/30
In the paper, we consider the problem of variable rotational speed control for a wind turbine with the pitch fixed from the view point of scheduling by wind speed. For this problem, we apply LPV (Line...
Effects of Pin Count and Faller Pitch of Gill-Drawing Frame on Irregularities of Sliver Made from Fine Denier Fibers
Fine denier fiber Pin-drafting Nip gauge Pin density Pitch between moving gill-faller bars
2009/4/21
In order to improve the quality of sliver made from fine denier fibers, a pin drafting method was investigated. Especially, the study of fiber control in drafting zone, pin count and pitch between mo...
