Indirect measurement of the electrocaloric effect
… the various reports showed that the indirect method of measuring cooling (described in the following sections) did not usually agree with the direct method (actually measuring temperature change with a thermometer). However, there was no obvious systematic error: sometimes the …

A statistical investigation of ozone exposure assessment by direct and indirect measurement
Recent studies have proposed the application of exposure-based criteria in developing alternative primary ambient ozone standards. Historically, epidemiological studies of ozone have approached exposure assessment in a simplistic fashion with simplistic methods used to estimate ambient ozone …

Development of a Multidimensional Scale to Measure Attitudes Toward Workers With a Disability
… in their application in organizational settings. Indirect measurement has been beyond the scope of most organizations due to the complex and expensive implementation of these methods. Direct measures have been shown to be susceptible to threats to internal validity, such as reactivity and socially …

Quality Assurance Testing, and Sensitivity Studies for the SNO+ Experment
… understanding of detector systematics are key. Indirect background measurements and energy systematics have been studied. A quality assurance testing system was created and implemented. The system detects the oxygen contamination of liquid scintillator as an indirect measurement of radon-222 …

Survey of Knowledge of Fifty Registered Professional Nurses Regarding Selected Factors of Indirect Blood Pressure Measurement
… factors that contributed to variations in the indirect measurement of blood pressure. It was thought that assessment of the nurses' knowledge could contribute to more effective nursing services by disclosing areas of weakness which could be strengthened by hospital in-service and nursing …

A comparative study of construction waste generation rate based on different construction methods used in construction projects in Malaysia
… SV methods applied in this study, namely direct measurement and indirect measurement. The data were collected from 12 social amenities projects at the construction stage which can be divided into the Conventional Construction Method (CCM), the Mixed Construction Method (MCM) and the …

Comparison of Two Potential Streamgage Locations on Scott Creek at Swanton Pacific Ranch, California
… challenges in gage construction and discharge measurement capabilities. A detailed flood frequency analysis was completed using a direct watershed comparison, direct equations developed by Waananen and Crippen, a Log Pearson Type III Frequency Distribution, a regional analysis, and two-station …

Clinical and ultrasonic estimation of fetal weight
… been found to be of limited value because of the indirect measurement of fetal mass. Since the introduction of ultrasound scanning techniques to obstetrics in the mid- 1960's, it has become possible to visualise the fetus and to make direct measurements of fetal anatomy. By using ultrasound, …

Finding the missing connection: diffusion-based tractography reconstruction of the acoustic radiation and other applications
… limitations. The inherent limits related to the indirect measurement of the diffusion signal, and the strong dependence of this technique on acquisition, models and algorithm parameters, prevents the reliable reconstruction of some major white matter bundles. This dissertation targets the …

An Invariant Extended Kalman Filter for Indirect Wind Estimation Using a Small, Fixed-Wing Uncrewed Aerial Vehicle
… weather stations and weather balloons. In situ measurements using a UAV can be obtained for the thermodynamic state of the ABL using dedicated sensors that directly measure pressure, temperature, and humidity whereas the kinematic state (wind velocity) can be measured directly, using, for …

An Exploratory Study of the Application of Carbon Nanotubes to Skin Friction Measurements
… 2D flow. The sensor is a non-intrusive, direct measurement device with a 2 x 2 mm square sensor head surrounded by a small gap on each side (~0.004 inches). The translation of the sensing element is due to the nanotubes bending when a shear force is applied to the sensor head. Displacements are …

Analysis of magnetohydrodynamic (MHD) activity using electron cyclotron emission (ECE) diagnostics on Alcator C-Mod tokamak
… in terms of spatiotemporal resolution, such indirect measurement opens the door to improved physical understanding of ELMs. In particular, it is the first to reveal the poloidal structure of an ELM.

Rethinking the dithiothreitol based PM oxidative potential: measuring DTT consumption versus ROS generation
… most damaging ROS – •OH. Rather than taking an indirect measurement of oxidative potential introduced by ROS, this study directly measured the generation rate of •OH. Sodium terephthalate, which is able to oxidize •OH forming 2-hydroxyterephthalic acid (2-OHTA) was chosen as the probe to measure …

Asymptotic theory for Bayesian nonparametric inference in statistical models arising from partial differential equations
… of recovering an unknown function from a linear indirect measurement corrupted by additive Gaussian white noise. We employ a nonparametric Bayesian approach with standard Gaussian priors, for which the posterior-based reconstruction corresponds to a Tikhonov regulariser with a reproducing kernel …

Zeitgenössische Vorurteile : Erfassung, Erklärung und Reduktion
… Saucier & Miller, 2003). The scale allows for an indirect measurement of contemporary prejudice. The German version RAS-G was validated with prejudice scales, scales to measure stereotypes and discriminating behavioural intentions. Further, the attitude dimensions Right-Wing-Authoritarianism (RWA, …

The Speciation of Dissolved Uranium in Marine Waters
… inorganic form in marine waters, there is some indirect evidence to suggest that organic and colloidal uranium are present. Uranium is well known for its association with organics material, such as humic and fulvic acids. The indirect measurement of organic uranium has also been reported in …

The media's role in the consolidation of democracy in South Africa: the case of the SABC's soap operas as a cultural public sphere
… borrowed from film and television theories. By indirect measurement, MCDA model is used in the study to evaluate how democracy is represented (promoted, negated, omitted) in various aspects of the text.
