The interpretation of the differential threshold in the central visual field
Documenta Ophthalmologica, 1986Computer assisted perimetry has revolutionised the investigation of the visual field. Experience of central field assessment with the Octopus Automated Perimeter shows that sensitivity recorded with target size 3 across all age groups can frequently be greater than the published normative values. Use of the latter values can therefore provide a serious

Progressive Differential Thresholding for Network Anomaly Detection
2011 IEEE International Conference on Communications (ICC), 2011In this paper, we propose a Progressive Differential Thresholding (PDT) framework for coordinated network anomaly detection. Under the proposed framework, nodes present on a packet's path progressively encode their opinion (malicious or benign) inside a packet.

Differential Threshold Measurement on the Light Reflex of the Human Pupil
Ophthalmologica, 19581. Introduction Before discussing the threshold of the pupil reflex, it seems necessary to state that its value depends mainly on intrinsic qualities of the individual nervous system and, in some degree, on the mechanical properties of the iris tissue.

Statistical Analysis of a Differential Threshold Logic Circuit Configuration
IEEE Transactions on Computers, 1976A differential current-switching circuit configuration is proposed for implementing threshold logic, and a first-order statistical analysis of the configuration is described. The configuration is intended for use within functional digital integrated circuits. It can be realized in a form that is fully compatible with conventional emitter-coupled logic (

A thresholding method based on two-dimensional fractional differentiation
Image and Vision Computing, 2009In this paper, we present a new thresholding technique based on two-dimensional fractional differentiation, that was obtained through the extension of the one-dimensional fractional differentiation. A new geometric interpretation of the two-dimensional fractional differentiation is also presented in the paper.

Psychophysical Differentiation of Pain by Threshold Methods
1992Pain represents an unpleasant, distressing, and agonizing sensation. It cannot be described in terms of perception only, but refers to a complex experience with concomitant psychophysical components. Acute pain serves warning and protection functions, whereas chronic pain is also characterized by emotional reactions such as anxiety and depression ...

Differential Asynchrony Thresholds for Auditory Pulse Trains
The Journal of the Acoustical Society of America, 1969Absolute and differential thresholds for a single temporal discontinuity, or “gap,” were obtained for auditory pulse trains as a function of: (1) the interpulse interval surrounding the gap region, and, (2) the magnitude of the reference gap. Under conditions implicating a spectral analysis, e.g., a large number of pulses at high pulse frequencies, the

Matching Forces: Constant Errors and Differential Thresholds
Perception, 1989A contralateral limb-matching procedure was used to study the perception of forces generated by the elbow flexor muscles. Subjects were required to generate forces ranging from 15 to 85% of their maximum voluntary contraction (MVC range: 169–482 N), and after achieving the target force to produce a force of the same perceived intensity with their ...

Differential implementations of threshold logic gates
Signals, Circuits and Systems, 2003. SCS 2003. International Symposium on, 2003This paper reviews differential implementations of threshold logic gates, detailing two classes of solutions: capacitive (switched capacitor and floating gate), and conductance/current.
