Reproducible measurements based on myocardial perfusion studies for patient follow-upAbstract: Our aim is to derive quantitative measurements from Myocardium Perfusion Scintigraphic (MPS) exams for drug trials on Myocardium re-perfusion. We are considering 19 patients imaged 6 times to measure the ...
The results we obtained are similar to those we find in the literature (CHR--0.53±0.01; RCHR--1.56±0.02; Carpal-Ulnar Distance Ratio--0.30±0.01). This study shows that these methods are reproducible and the values represent normal reference values that can be used in further kinematic ...
In the follow-up work of the CAESAR, Robinette and Daanen [20] compared virtual tape measurements over two different scanners and scanning teams and showed that measurements are highly reproducible within the US Army defined error limits (cf. ANSUR experiments). Reproducibility error in their ...
but they are not the same. Accuracy reflects how close a measurement is to a known or accepted value, while precision reflects how reproducible measurements are, even if they are far from the accepted value. Measurements that are both precise and accurate are repeatable and very close to true ...
Measurementsare observations that are made in reference to a known value or unit. One may measure the length of a road, the weight of a bag of produce, or even the amount of light emitted by a lightbulb. Measurements have everyday applications as individuals use them to convey messages to...

However, using completion resistors that are too large can result in increased noise and errors due to bias currents. SIGNAL CONDITIONING STRAIN GAGE CIRCUIT R1 VEX R2 EXC+ IN+ IN- EXC- R3 Strain Gages R3 Signal Conditioner Figure 7. A signal conditioner provides excitation and bridge ...
If that doesn't work, please contact support so we can address the problem. Abstract Human exposure studies, compared with cell and animal models, are heavily relied upon to study the associations between health effects in humans and air pollutant inhalation. Human studies vary in exposure ...
Consequently, while feasible and reproducible, the utility of ex vivo TM measurements as quality metric for CRC surgery was not demonstrated. Notably, few studies have previously investigated a survival relationship with ex vivo TM measurements, and of these, focus has been on populations ...
Sedimentation and free fluid formation in a cement slurry can dramatically impact the final set cement properties. To ensure that the samples used in this study were stable, and that the results presented are reliable and reproducible, standard API free fluid tests and sedimentation tests (BP settl...
