Analytically Riesz operators and Weyl and Browder type theorems [PDF]

open access: yesFunctional Analysis, Approximation and Computation 7 (2) (2015),1-7, 2015
Several spectra of analytically Riesz operators will be characterized. These results will led to prove Weyl and Browder type theorems for the aforementioned class of operators.

Operations research investigations of satellite power stations [PDF]

open access: yes
A systems model reflecting the design concepts of Satellite Power Stations (SPS) was developed. The model is of sufficient scope to include the interrelationships of the following major design parameters: the transportation to and between orbits ...

Avoidable Hospitalizations in Persons With Rheumatoid Arthritis: A Population‐Based Study Using Administrative Data

open access: yesArthritis Care &Research, EarlyView.
Objective We estimated incidence rates of avoidable hospitalizations by persons with rheumatoid arthritis (RA) relative to the general population. Methods We identified individuals meeting a validated case definition for RA based on International Classification of Diseases, Ninth Revision, Clinical Modification (ICD‐9‐CM) and ICD‐10‐CA codes in years ...

An introduction to the mincut graph of a graph [PDF]

open access: yesarXiv, 2018
There is a well-documented research programme on graph operators which addresses questions such as `Which graphs appear as images of graphs?'; `Which graphs are fixed under the operator?'; `What happens if the operator is iterated?' In this paper, we introduce an intersection graph called the mincut graph and state its characteristics.

Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.
