Integer multiplication with overflow detection or saturation

IEEE Transactions on Computers, 2000
High-speed multiplication is frequently used in general-purpose and application-specific computer systems. These systems often support integer multiplication, where two n-bit integers are multiplied to produce a 2n-bit product. To prevent growth in word length, processors typically return the n least significant bits of the product and a flag that ...

Detecting GAN-Generated Imagery Using Saturation Cues

2019 IEEE International Conference on Image Processing (ICIP), 2019
Image forensics is an increasingly relevant problem, as it can potentially address online disinformation campaigns and mitigate problematic aspects of social media. Of particular interest, given its recent successes, is the detection of imagery produced by Generative Adversarial Networks (GANs), e.g. ‘deepfakes’.

Pulse oximetry saturation patterns detect repetitive reductions in airflow

Journal of Clinical Monitoring and Computing, 2011
Postoperative patients exhibiting signs or symptoms of obstructive sleep apnea (OSA) have been identified to be at increased risk for respiratory compromise. One of the key markers associated with OSA is repetitive reductions in airflow (RRiA). A real-time pulse oximeter saturation pattern recognition algorithm (OxiMax SPD™ intended for adult in ...

Additive fault detection in nonlinear dynamic systems with saturation

ISA Transactions, 2005
This paper describes the effects of input saturation on the performance of a model-based fault detection method based on the input-output parity equation approach. For this purpose, the level control of a chemical reactor has been chosen as the control process to be analyzed, where the saturation of the dynamic process is due to the inflow control ...

Sahlgren's Saturation Test for Detecting and Grading Acquired Dyschromatopsia

American Journal of Ophthalmology, 1981
A new sorting test requires only two minutes for quantitative estimation of saturation thresholds for bluish pigment colors. The test is highly sensitive to and specific for differences between normal subjects and individuals with acquired color vision defects.

Detection of movement artifact in recorded pulse oximeter saturation

European Journal of Pediatrics, 1997
Movement artifact (MA) must be detected when analysing recordings of pulse oximeter saturation (SpO2). Visual analysis of individual pulse waveforms is the safest, but also the most tedious, method for this purpose. We wanted to test the reliability of a computer algorithm (Edentec Motion Annotation System), based on a comparison between pulse and ...

Current-Transformer Saturation Detection With Genetically Optimized Neural Networks

IEEE Transactions on Power Delivery, 2005
Application of the genetic algorithm for the optimization of the artificial-neural-network (ANN)-based current-transformer (CT) saturation detector is presented. To determine the most suitable ANN topology for the CT state classifier, the rules of evolutionary improvement of the characteristics of individuals by concurrence and heredity are used.

In vivo detection of hemoglobin oxygen saturation and carboxyhemoglobin saturation variations with photoacoustic microscopy

SPIE Proceedings, 2012
A method for noninvasive simultaneously detecting hemoglobin oxygen saturation (SO2) and carboxyhemoglobin saturation (SCO) in subcutaneous microvasculature with multi-wavelength photoacoustic microscopy (PAM) is presented. In vitro blood samples mixed with different concentration of carboxyhemoglobin were used to testify the feasibility and accuracy ...

Current-Transformer Saturation Detection Using Savitzky-Golay Filter

IEEE Transactions on Power Delivery, 2016
A new application of the Savitzky-Golay (SG) filters in current-transformer saturation detection is proposed. The ability of the SG filters to handle noisy signals improves the robustness of the detection process in the presence of noise while requiring only low computational effort.

On detecting TCP path saturation in LTE networks

International Journal of Communication Systems, 2017
SummaryA significant part of the data in mobile networks is transferred as bulk data with transmission control protocol (TCP) as apps or video downloads. When the video takes too long to start, users are more prone to abandon watching, which eventually leads to decreased revenue for the content provider.
