On p-electron conjugation in the five-membered ring of fluoranthene-type benzenoid hydrocarbons [PDF]

open access: yesJournal of the Serbian Chemical Society, 2009
A fluoranthene-type benzenoid hydrocarbon (FTBH) is a polycyclic conjugated system obtained by joining two ordinary benzenoid hydrocarbons so as to form a five-membered ring.

Minimizing detent force of permanent magnet linear synchronous machines by designing mover using mesh-level stochastic shaping

open access: yesEnergy Reports, 2023
Detent force is an inherent problem of permanent magnet linear synchronous machines (PMLSMs). In this paper, a mesh-level design methodology is proposed to minimize the detent force on PMLSMs.

Controlling Attribute Effect in Linear Regression [PDF]

open access: yes2013 IEEE 13th International Conference on Data Mining, 2013
In data mining we often have to learn from biased data, because, for instance, data comes from different batches or there was a gender or racial bias in the collection of social data. In some applications it may be necessary to explicitly control this bias in the models we learn from the data. This paper is the first to study learning linear regression

The reciprocal linear effect, a new optical effect of the Sagnac type

open access: yesOpen Physics, 2023
The Sagnac effect can be demonstrated with light propagating either along a circular contour or, as done by Wang et al., back and forth along a linear contour.

Beyond the Linear Stark Effect: A Retrospective

open access: yesAtoms, 2018
A review of studies of the electric-field influence on spectral lines is presented, beginning from the discovery of the Stark effect, and in particular focused on phenomena related to the effects of the plasma microfield non-uniformity.

Effect Displays in R for Generalised Linear Models

open access: yesJournal of Statistical Software, 2003
This paper describes the implementation in R of a method for tabular or graphical display of terms in a complex generalised linear model. By complex, I mean a model that contains terms related by marginality or hierarchy, such as polynomial terms, or ...

Tourism and Green Development: Analysis of Linear and Non-Linear Effects

open access: yesInternational Journal of Environmental Research and Public Health, 2022
Clarifying the relationship between tourism and green development is conducive to promoting the harmonious coexistence of tourism industry benefits and economic and environmental systems. The externalities of tourism on economies and the environment have sparked numerous fascinating academic research debates; however, few studies have considered the ...

The Case for Using the General Linear Model as a Unifying Conceptual Framework for Teaching Statistics and Psychometric Theory

open access: yesJournal of Methods and Measurement in the Social Sciences, 2015
The present paper argues for teaching statistics and psychometric theory using the GLM as a unifying conceptual framework. This helps students understand what analyses have in common, and also provides a firm grounding for understanding that more general
