Prezentizmus a prítomný moment (Presentism and the present moment )

open access: yesOstium, 2017
The paper examines the relation between presentism and the experience of the present moment. Some presentists believe that our experience of the present moment is in correspondence with the presentistic theory of the present moment. This link between our

Conditional moment closures for turbulent reacting flows [PDF]

open access: yes, 2003
Mathematical modelling of the turbulent combustion process is becoming increasingly applied in calculations to assist in the design and analysis of practical combustion devices for efficiency-improvement and emission reduction. The current requirement to

Interactive effects of joint angle, contraction state and method on estimates of achilles tendon moment arms [PDF]

open access: yes, 2013
Copyright @ 2013 Human Kinetics, IncThe muscle-tendon moment arm is an important input parameter for musculoskeletal models. Moment arms change as a function of joint angle and contraction state and depend on the method being employed.

Low power control for magnetically suspended control moment gyro based on current adaptive adjustment‐gimbal angular velocity feedforward method

open access: yesIET Electric Power Applications, 2022
Magnetically suspended control moment gyro (MSCMG) outputs gyro moment by changing the direction of the rotor angular momentum to adjust the spacecraft attitude.

Analysis of non scalar control problems for parabolic systems by the block moment method

open access: yesComptes Rendus. Mathématique, 2023
This article deals with abstract linear time invariant controlled systems of parabolic type. In [9], with A. Benabdallah, we introduced the block moment method for scalar control operators.

On bounded complex Jacobi matrices and related moment problems in the complex plane [PDF]

open access: yesSurveys in Mathematics and its Applications, 2023
In this paper we consider the following moment problem: find a positive Borel measure μ on ℂ subject to conditions ∫ zn dμ = sn, n∈ℤ+, where sn are prescribed complex numbers (moments).

Continued fractions which correspond to two series expansions and the strong Hamburger moment problem [PDF]

open access: yes, 2012
Just as the denominator polynomials of a J-fraction are orthogonal polynomials with respect to some moment functional, the denominator polynomials of an M-fraction are shown to satisfy a skew orthogonality relation with respect to a stronger moment ...

TRACKING OF MULTIPLE HUMAN OBJECTS USING COMBINATION OF DAUBECHIES COMPLEX WAVELET TRANSFORM AND ZERNIKE MOMENT [PDF]

open access: yesICTACT Journal on Image and Video Processing, 2020
The goal of multi object tracking is to find location of the target objects in number of consecutive frames of a video. Tracking of multiple human objects in a scene is one of the challenging problems in computer vision applications due to illumination ...

Optimization problems for construction foundations

open access: yesLietuvos Matematikos Rinkinys, 2000
The mathematical models for optimization of grillage-type foundations are presented. Minimi­sing of maximum in absolute value vertical reactive force, bending moment, and reaction-bending moment together is sought.

Moment Problems in Hereditary Function Spaces

open access: yesConcrete Operators, 2019
We introduce a concept of hereditary set of multi-indices, and consider vector spaces of functions generated by families associated to such sets of multi-indices, called hereditary function spaces.
