ck-means and fck-means: Two Deterministic Initialization Procedures for k-means Algorithm Using a Modified Crowding Distance

open access: yesActa Informatica Pragensia, 2023
This paper presents two novel deterministic initialization procedures for k-means clustering based on a modified crowding distance. The procedures, named ck-means and fck-means, use more crowded points as initial centroids.

A vortex-implanted initialization scheme for the mesoscale eddy prediction: Idealized experiments

open access: yesFrontiers in Marine Science, 2022
Mesoscale eddy prediction has been a big challenge to oceanographers and marine environment forecasters. Although the traditional initialization for the prediction, i.e., through assimilating the satellite-derived sea level anomalies (SLA) into a model ...

Initials Within Initials [PDF]

open access: yesThe Library, 2019
Abstract This paper examines a number of sixteenth-century display capitals whose design incorporates the initials of either their owners or their creators. It then recounts the history of a small group of existing capitals that were modified to include the initials of those responsible for the text in which they appear.

Impact of initial conditions on the initiation of ferroresonance

open access: yesInternational Journal of Electrical Power & Energy Systems, 2009
The impact of initial conditions on the initiation of ferroresonance is investigated. The investigation is carried out by simulating the behavior of the model of a 275 kV electromagnetic voltage transformer circuit for a range of practical values of other system parameters.
