However, resource provisioning may also be achieved without predicting the future workload as discussed in [26], where the authors propose a technique for dynamically adapting thresholds to meet QoS targets.
Frings et al. compared various threshold settings [12] in [18F]FLT PET and found that the 50% background adapted threshold, A50%, had the best trade-off between success rate and repeatability.
Figure 6 shows the response of metrics and their adapted thresholds.
Pre-adapt thresholds differed from thresholds after adapting to both the original (F 1,29) = 68.9, p < 0.001) or sharpened images (F 1,29) = 73.5, p < 0.001), while the original and sharpened adapting conditions did not differ from each other (F 1,29) = 0.145, p = 0.71).
In order to achieve accuracy of 0.1 μm and below, we additionally implemented a segmentation algorithm based on geodesic active contours that allow for arbitrary cross sections and uses locally adapted thresholds.
Clinicians must be aware of this increased risk profile and should adapt thresholds for clinical observation and repeated cranial imaging studies for respective patients.
With the help of PT and HeRATE, the current and predicted thermal environment is described in health-related frequencies of exceeding locally adapted thresholds based on daily values at a fixed time (noon = 12 MLT) which is representative for a few hours around noon.
In this work, we adopt the OTSU algorithm to determine a self-adapting threshold.
The histogram of a distant matrix (obtained with Principal Component Analysis technique) and the variance of a mean image allow adapting the threshold level according to outdoor conditions.
However, increasing the 'easiness' of examinations could be balanced by adapting the threshold for a pass for candidates.
This finding supports the notion that modulating the execution drift-rate in our model reflects similar computations as adapting the threshold in the traditional drift-diffusion models without a dynamic pressure on the drift rate.
