Off-design analysis and control of a wood-fired combined-cycle power plant

Creator:: Brawn, Robert Charles
Abstract:: This report presents the off-design analysis of various wood-fired combined-cycle power plants using a computer model to simulate plant performance. The combined-cycle systems investigated are characterized by having a woodfueled combustor, an indirect-fired gas turbine, and a Rankine steam cycle. This work was conducted as part of a larger biomass...

Abstract:: Oregon has a rich history in the production of fruits, berries, vegetables, and ornamental crops; the state’s national and international reputation for delivering high-quality products is well-established and well-deserved. In the past, agriculture and forestry were the foundation of Oregon’s economy. Although other activities now are equal in size to...

Bipolar piezoelectric fatigue of Bi(Zn0.5Ti0.5)O3-(Bi0.5K0.5)TiO3-(Bi0.5Na0.5)TiO3 Pb-free ceramics

Creator:: Patterson, Eric A. and Cann, David P.
Abstract:: The piezoelectric fatigue behavior of Pb-free ceramics based on solid solutions of Bi(Zn₀.₅Ti₀.₅)O₃-(Bi₀.5K₀.₅)TiO₃-(Bi₀.₅Na₀.₅)TiO₃ was characterized at 50 kV/cm after 10⁶ bipolar cycles. Ferroelectric compositions containing 2.5% Bi(Zn₀.₅Ti₀.₅)O₃ exhibited only minor losses in maximum strain (~10%). In compositions with 5% Bi(Zn₀.₅Ti₀.₅)O₃ that exhibit large electric field-induced strains, the electromechanical strain actually...

Electromechanical strain in Bi(Zn1/2Ti1/2)O3–(Bi1/2Na1/2)TiO3–(Bi1/2K1/2)TiO3 solid solutions

Creator:: Patterson, Eric A., Cann, David P., Pokorny, Jan, and Reaney, Ian M.
Abstract:: Solid solutions ceramics of the Bi(Zn0.5Ti0.5)O-3-(Bi0.5K0.5)TiO3-(Bi0.5Na0.5)TiO3 ternary system for <20 mol. % BZT were created and confirmed to be single phase using x-ray diffraction. The dielectric dispersion showed decreasing T-max of the dielectric spectrum with a broadening of the transition with increasing BZT content. At 2.5BZT-40BKT-57.5BNT, a secondary transition commonly...

Effects of coupled atomic states on the resonance scattering of radiation

Creator:: Srivastava, Rajendra Prasad
Abstract:: The excitation and decay probabilities for resonance scattering of radiation from an atom with two coupled excited states and one ground state in an external static field are calculated as a function of time and frequency. Various oscillatory behaviors are found in all the probabilities. These oscillations depend on the...

Pile hammer selection by driving stress analysis

Creator:: Barrero-Quiroga, Franklin
Abstract:: This paper presents an application of the wave equation to the problem of selecting a driving hammer for prestressed concrete piles. The potentially damaging effects of these types of hammers on various prestressed concrete piles were analyzed by means of parametric studies carried out on a hypothetical group of problems...

Hot electron effects in N-channel MOSFET's

Creator:: Or, Siu-shun Burnette
Abstract:: The purpose of this work is to develop a new model for LDD n-MOSFET degradation in drain current under long-term AC use conditions for lifetime projection which includes a self-limiting effect in the hot-electron induced device degradation. Experimental results on LDD n-channel MOSFETs shows that the maximum drain current degradation...
