The paper presents a system using Decision tree, Particle swarm optimization, and Support vector regression to design a Median-type filter with a 2-level impulse detector for image enhancement, called DPSM filter. First, it employs a varying 2-level hybrid impulse noise detector (IND) to determine whether a pixel is contaminated by impulse noises or not. The 2-level IND is constructed by a deci...

OBJECTIVE: This study compared the results of the caloric test with those of the video head impulse test obtained during the same session and evaluated whether the former can be used to screen for non-acute vestibular dysfunction. METHODS: A total of 157 participants complaining of dizziness with vestibular characteristics of varying durations and clinical courses completed the caloric test a...

We present a new model of impulse buying, based on a social constructionist theory, which addresses some of the short-comings of previous models from economics, consumer behaviour, and psychology. Our model predicts that products are impulsively bought to reflect self-identity. Thus gender, as a major social category, should influence both the products bought impulsively and the buying consider...

We calculate the force operator for a charged particle in the field of an Aharonov–Bohm flux line. Formally this is the Lorentz force, with the magnetic field operator modified to include quantum corrections due to anomalous commutation relations. For stationary states, the magnitude of the force is proportional to the product of the wavenumber k with the amplitudes of the ‘pinioned’ components...

Action potentials (APs) and impulse responses in the soma and axon of the rapidly and slowly adapting (SA) abdominal stretch receptor neurons of the crayfish (Astacus leptodactylus) were recorded with single microelectrode current-clamp technique. Impulse frequency response to constant current injection was almost constant in the SA neuron while the response decayed completely in the rapidly ad...

We show that the original velocity—impulse density the impulse density. formulation of Oseledets is marginally ill-posed for the inviscid flow, At a first sight, the impulse density formulation also proand ...

Formally this is the Lorentz force, with the magnetic eld operator modiied to include quantum corrections due to anomolous commutation relations.

OBJECTIVE We examined the eye movement response patterns of a group of patients with bilateral vestibular loss (BVL) during suppression head impulse testing. Some showed a new saccadic strategy that may have potential for explaining how patients use saccades to recover from vestibular loss. METHODS Eight patients with severe BVL [vestibulo-ocular reflex (VOR) gains less than 0.35 and absent o...

Impulse The word ’impulse’ is used in many areas in different ways. In classical mechanics, the impulse is the integral of force with respect to time. It is also used to refer to a fast-acting force, which is often idealized by a step function or a delta function. In this text, it is used to represent any functional form of pressure increase, either static or transient, which can generate obser...
