Abstract:

An inverse problem for unsteady forced convection in an annular duct is presented. The simulated temperature data taken at the outer wall are used to estimate the time-dependent axially varying surface heat flux distribution at the inner wall of the annular passage. No prior information on the functional form of the unknown wall heat flux is needed in the inverse method. The effects of the functional form of the wall heat flux, the number of the measurement points, and the measurement errors on the accuracy of the estimation are investigated. It is shown that the reconstruction of the timewise

This research investigated potential fire hazards originating in hidden areas of pressurized sections of aircrafts. The objective was to establish a laboratory-scale flammability test method to predict the behavior of fire propagation under real fire conditions. A confined fire apparatus (CFA) was designed and constructed, and several tests were conducted to better understand the involved mechanisms and their consequences and to estimate flame spreading in hidden-zone fires.

The Luzon Strait (LS) is a key region for estimating carbon sources and sinks in the South China Sea (SCS) and is highly influenced by the Kuroshio Current (KC) and typhoons. Understanding the variations in the sea surface partial pressure of carbon dioxide (pCO2-sw) under the combined effects of typhoons and KC in this region is crucial for estimating local and regional changes in ocean carbon flux. Based on valuable in situ pCO2-sw and remote sensing data, this study aimed to reveal the temporal variations and the physical mechanisms of pCO2-sw variations under the comprehensive effects of b

Comparison of model-computed winds, wind stress, and heat flux with in situ data collected on moored meteorological buoys in the western GoM and over GB in 1995 shows that during the passage of atmospheric fronts over this region, MM5 provides a reasonable prediction

In systems neuroscience, neural activity that represents movements or sensory stimuli is often characterized by spatial tuning curves that may change in response to training, attention, altered mechanics, or the passage of time. A vital step in determining whether tuning curves change is accounting for estimation uncertainty due to measurement noise. In this study, we address the issue of tuning curve stability using methods that take uncertainty directly into account.

When the rotor flux linkage of the motor undergoes sudden changes, the nonlinear flux linkage model shows a speed fluctuation of 5%, whereas the parameter-adaptive flux linkage model reduces the error to 0.6%.

Abstract For estimating lateral flux in the ocean using fixed or mobile platforms, the authors present a method of analyzing the estimation error and designing the sampling strategy. When an array of moorings is used, spatial aliasing leads to an error in flux estimation. When an autonomous underwater vehicle (AUV) is run, measurements along its course are made at different times. Such nonsynopticity in the measurements leads to an error in flux estimation. It is assumed that the temporal–spatial autocovariance function of the flux variable can be estimated from historical data or ocean models

A method for real-time estimation of rotor flux linkage of permanent-magnet synchronous machines (PMSMs) under both steady state and free-running conditions is proposed in this paper. At steady state, a method for the estimation of rotor flux linkage is proposed based on the injection of variable-period zero-voltage perturbation, of which the accuracy is irrespective of the influence of voltage-source inverter (VSI) nonlinearity. Moreover, for the estimation of rotor flux linkage under free-running condition, due to system inertia after shutdown or fault in the motor driver, an effective appro

Abstract The aim of this contribution is to provide an overview of the calculation procedures of risk analysis, that is, the effects and consequences of pool fires. Fires and explosions are the most significant and most common causes of damage to equipment and of injuries and death in industry. Damages are a direct consequence of the generated heat flux. Mathematical tools for the prediction of heat flux at a distance can be divided into four classes: semi-empirical models, field models, integral models and zone models. Semi-empirical modeling is a relatively simple technique providing models

O objetivo do presente trabalho foi a validação das predições da dinâmica ruminal e pós-ruminal dos nutrientes e do crescimento microbiano no rúmen, usando as equações do sistema Cornell. O experimento foi realizado durante as estações chuvosa e seca do ano de 1996, em uma área de pastagem natural localizada no município de Viçosa (MG). Foram utilizados novilhos canulados no esôfago, rúmen e abomaso, durante dois períodos experimentais em cada estação, e usados indicadores externos (Cr2O3 e Eu) para estimativa do consumo e da taxa de passagem da digesta no rúmen. Foram determinados os fluxos d

Abstract:

To investigate the impact of two CO2 observation datasets obtained from the Korean Peninsula on the surface CO2 flux estimation over Asia, the two datasets are assimilated into the CarbonTracker (CT) inverse modeling system and the estimated surface CO2 fluxes are analyzed. Anmyeon-do (AMY) and Gosan (GSN) sites in the Korean Peninsula have observed surface CO2 mole fraction since the late 1990s. To investigate the effect of assimilating the additional Korean observations on the surface CO2 flux estimation over Asia, two experiments are conducted. The reference experiment (CNTL) only assimilat

Abstract:

Introduction. In the distributed and autonomous generation systems using renewable energy sources, low-power generating units (not more than 100-200 kW) based on microturbines function. Microturbines operate most efficiently at high rotational speeds. In this regard, the generator running with a microturbine must also be a high-speed one. A generator is a switched reluctance electric machine (EM) that needs information on the rotor position. It is difficult to use a position sensor in such mechanisms at high speeds. This paper discusses the issues of sensorless control of a high-speed switched
