An extension of the basic local independence model to multiple observed classifications

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The basic local independence model (BLIM) is appropriate in situations where populations do not differ in the probabilities of the knowledge states and the probabilities of careless errors and lucky guesses of the items. In some situations, this is not the case. This work introduces the multiple observed classification local independence model

Differentiating Test Frequency and Self‐Heating Effects on the Fatigue Behavior of Normalized SAE 1045 Steel by In Situ Multisensor Monitoring

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT In this research, the fatigue behavior of a normalized SAE 1045 (C45E, 1.1191) steel was investigated at test frequencies between 5 and 260 Hz. The focus was on differentiating between frequency‐induced lifetime extension and lifetime‐reducing self‐heating phenomena.

Application of shifted Vieta-Lucas polynomials for the numerical treatment of Volterra-integro differential equations

Proceedings of the Nigerian Society of Physical Sciences
In this study, the numerical solution of the Volterra-integro differential equations was obtained by applying the variational iteration strategy with the shifted Vieta-Lucas polynomials. The proposed method builds the shifted Vieta-Lucas polynomials for

Back Pain and Prospective Frailty Status Among Older Men: Findings From the MrOS Study

Journal of the American Geriatrics Society, EarlyView.
ABSTRACT Background The association between back pain and frailty is uncertain. This study examined the association between back pain in older men and prospective frailty status an average of 7 years later. Methods Prospective cohort study using data from the Osteoporotic Fractures in Men Study.

q-GENERALIZATION OF BIPERIODIC FIBONACCI AND LUCAS POLYNOMIALS

, 2017
In this paper, we de fine q-analogue of the biperiodic Fibonacci and Lucas polynomials. We obtain generating function and several properties of these polynomials. We also define q-analogue of the biperiodic incomplete Fibonacci and Lucas polynomials.

Representing by several orthogonal polynomials for sums of finite products of Chebyshev polynomials of the first kind and Lucas polynomials

Advances in Difference Equations, 2019
In this paper, we investigate sums of finite products of Chebyshev polynomials of the first kind and those of Lucas polynomials. We express each of them as linear combinations of Hermite, extended Laguerre, Legendre, Gegenbauer, and Jacobi polynomials ...

Derivations and Identitites for Fibonacci and Lucas Polynomials

The Fibonacci Quarterly, 2013
We introduce the notion of Fibonacci and Lucas derivations of the polynomial algebras and prove that any element of kernel of the derivations defines a polynomial identity for the Fibonacci and Lucas polynomials. Also, we prove that any polynomial identity for Appel polynomial yields a polynomial identity for the Fibonacci and Lucas polynomials and ...

Self‐Ratings, Partner Perceptions, and Ideal Partner Preferences of Gelotophobia, Gelotophilia, and Katagelasticism in Couples: Congruence and Associations With Relationship Satisfaction

Journal of Personality, EarlyView.
ABSTRACT Objective How people deal with ridicule and being laughed at plays a role for romantic relationships. Gelotophobia (fear of being laughed at), gelotophilia (joy in being laughed at), and katagelasticism (joy in laughing at others) describe individual differences in dealing with laughter.
