Vestas V90-3MW Wind Turbine Gearbox Health Assessment Using a Vibration-Based Condition Monitoring System

open access: yesShock and Vibration, 2016
Reliable monitoring for the early fault diagnosis of gearbox faults is of great concern for the wind industry. This paper presents a novel approach for health condition monitoring (CM) and fault diagnosis in wind turbine gearboxes using vibration ...

Conditions for the acceptance of deontic conditionals.

open access: yesCanadian Journal of Experimental Psychology / Revue canadienne de psychologie expérimentale, 2004
Recent psychological research has investigated how people assess the probability of an indicative conditional. Most people give the conditional probability of q given p as the probability of if p then q. Asking about the probability of an indicative conditional, one is in effect asking about its acceptability. But on what basis are deontic conditionals

On conditional decomposability [PDF]

open access: yesSystems & Control Letters, 2012
The requirement of a language to be conditionally decomposable is imposed on a specification language in the coordination supervisory control framework of discrete-event systems. In this paper, we present a polynomial-time algorithm for the verification whether a language is conditionally decomposable with respect to given alphabets.

Effect of different catalyst preparation methods on the synthesis of carbon nanotubes with the flame pyrolysis method

open access: yesAIP Advances, 2018
The Flame pyrolysis method used to synthesize carbon nanotubes was studied in this work. In order to improve the quality of synthesized carbon nanotubes, it is important to change the corresponding natures of the catalyst.

Cooling Performance Enhancement of Air-Cooled Condensers by Guiding Air Flow

open access: yesEnergies, 2019
Adverse wind effects on the thermo-flow performances of air-cooled condensers (ACCs) can be effectively restrained by wind-proof devices, such as air deflectors.

A New Method of Identifying the Limit Condition of Injection Pump Wear in Self-Ignition Engines

open access: yesEnergies, 2020
The quality or reliability of diagnostics is understood as obtaining the most likely diagnosis, and finding possible causes leading to incorrect operation of the system. In real engine running conditions it is often very difficult.

Conditions and conditioning, stability and stabilization

open access: yesApplied Mathematics and Computation, 1989
The author reviews several concepts, including condition and stability, useful for dealing with the numerical solution of boundary value problems. In order to investigate a class of second order scalar problems, a generalization of the concept of well-conditioning is considered. The results are applied to the Korteweg-de Vries and Burgers equations.

To condition or not to condition—That is the question: The evolution of nonmyeloablative conditions for transplantation [PDF]

open access: yesExperimental Hematology, 2016
In 1985, Eugene Cronkite and his colleagues published, in Experimental Hematology, data indicating that five consecutive "transfusions" of large numbers of marrow cells significantly increase the number of donor-derived cells detected by day 10 of a spleen colony-forming assay, the most primitive hematopoietic cells detectable at that time, present in ...

Analysis of the Effects of Blade Installation Angle and Blade Number on Radial-Inflow Turbine Stator Flow Performance

open access: yesEnergies, 2018
Organic Rankine cycle (ORC) is a reliable technology to recover low-grade heat sources. The radial-inflow turbine is a critical component, which has a significant influence on the overall efficiency of ORC system.

Operant Conditioning [PDF]

open access: yesAnnual Review of Psychology, 2003
Operant behavior is behavior “controlled” by its consequences. In practice, operant conditioning is the study of reversible behavior maintained by reinforcement schedules. We review empirical studies and theoretical approaches to two large classes of operant behavior: interval timing and choice.
