Trigonometric functions of nonlinear quantities

open access: yes, 1994
Trigonometric functions of nonlinear quantities are introduced. Functions of the form {line_integral}(x{sup a}), {line_integral}(x{sup y}), and {line_integral}{sup n}(x{sup a}) are reported, where {line_integral} is a trigonometric function such as cos ...

Analytical stress solution framework for lined compressed air energy storage chambers and its application to safe burial depth determination and supporting effectiveness evaluation

open access: yesDeep Underground Science and Engineering, EarlyView.
An analytical framework delivers a closed‐form stress solution for lined compressed air energy storage chambers, enabling the determination of the minimum safe burial depth. The solution quantitatively evaluates lining support effectiveness, offering a reliable tool for chamber design and optimization.

Dynamic response at the terminus of oblique intersecting joints subjected to stress waves

open access: yesDeep Underground Science and Engineering, EarlyView.
This study derives the propagation equation for stress waves impinging upon nonlinear oblique intersecting joints. It analyzes the dynamic response at the terminus of nonlinear oblique intersecting joints subjected to stress waves. Abstract To investigate the dynamic response at the terminus of oblique intersecting joints subjected to stress waves, a ...

Extension of Oppenheim's Problem to Bessel Functions

open access: yesJournal of Inequalities and Applications, 2007
Our aim is to extend some trigonometric inequalities to Bessel functions. Moreover, we deduce the hyperbolic analogue of these trigonometric inequalities, and we extend these inequalities to modified Bessel functions.

A Three‐Parameter Continuum Timoshenko Beam Framework for Evaluating Higher‐Mode Effects in High‐Rise Buildings With Rotational and Translational Base Flexibility

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Higher‐mode effects can significantly amplify seismic demands in high‐rise buildings, causing unintended damage over the building height. Engineered mechanisms are introduced at the base of these structures to mitigate higher‐mode effects. Existing continuum formulations for base‐flexible buildings commonly idealize the superstructure as a ...

Higher rank elliptic partition functions and multisymmetric elliptic functions

open access: yesNuclear Physics B
We introduce and investigate a class of glM+1 partition functions which is an extension of the one introduced by Foda-Manabe. We characterize the partition functions by a nested version of Izergin-Korepin analysis, and determine the explicit forms, for ...

Teaching Transformations of Trigonometric Functions with Technology

open access: yesJournal of Interactive Media in Education, 2020
Trigonometry is integral to mathematics education. The field of trigonometry plays a crucial role in the study of mathematics and its applications. Despite the importance of the subject, students struggle to understand trigonometric constructs such as ...

Pelvic axial rotation in hindlimb lame horses changes after diagnostic analgesia

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Visual assessment of mild to moderate hindlimb lameness has low sensitivity and specificity, potentially leading to flawed diagnostic procedures. Pelvic axial rotation (roll) makes the assessment more complex but is also a potential source of information. Objectives To describe pelvic roll patterns in horses with unilateral hindlimb

Periodontal disease, biomarkers of ADRD risk, and cognitive functioning

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Periodontitis is a hypothesized risk factor for cognitive impairment. Many prior studies lack information on biological markers of Alzheimer's disease and related dementias (ADRD) risk or genetic risk markers. We assessed the association between periodontitis, biological markers of ADRD risk, and cognitive test performance with ...
