Modified poisson series to implement the method of multiple scales [PDF]
Mathematical Methods in the Applied Sciences, 2016 The method of multiple scales is a global perturbation technique that has resulted to be very useful in perturbed ordinary differential equations characterized by disparate time scales. The general principle behind the method is that the solution to the differential equation is uniformly expanded in terms of two or more independent variables, referred ...

Geosensor Network Optimisation to Support Decisions at Multiple Scales
, 2023 Geosensor networks are often used to monitor processes at different spatial scales. Existing approaches for configuring geosensor locations (i.e. sample design) do not address two key challenges: 1) they are limited to a single scale of analysis and do ...

Method of multiple scales with three time scales [PDF]
PAMM, 2007 AbstractSome confusion appears in the literature regarding the extension of the method of multiple scales to three or more time scales. While the work of Murdock and Wang [1] correctly indicates some obstructions to such an extension in some types of problems, other work suggests that the extension should almost never be possible [2]. These pessimistic

An IRT Analysis of Motive Questionnaires: The Unified Motive Scales [PDF]
, 2012 Multiple inventories claiming to assess the same explicit motive (achievement, power, or affiliation) show only mediocre convergent validity. In three studies (N = 1685) the structure, nomological net, and content coverage of multiple existing motive ...

Experience of Identity Change in People Who Reported a Diagnosis of Multiple Sclerosis : A Qualitative Inquiry [PDF]
, 2019 Background: A diagnosis of multiple sclerosis (MS) can lead to changes to a person’s sense of self. The aim of this study was to investigate the subjective experience of identity change and subsequent adjustment to MS.
