A modified logarithmic spiral method for determining passive earth pressure
Journal of Rock Mechanics and Geotechnical Engineering, 2018 In this study, a modified logarithmic spiral method is proposed to determine the passive earth pressure and failure surface of cohesionless sloping backfill, with presence of wall–soil interface friction.

Broadband spin-controlled focusing via logarithmic-spiral nanoslits of varying width [PDF]
Laser and Photonics Reviews, 2015 This work presents analytical, numerical and experimental demonstrations of light diffracted through a logarithmic spiral (LS) nanoslit, which forms a type of switchable and focus-tunable structure.

Zbornik radova, 2022 U ovom radu detaljnije se proučavaju svojstva logaritamske spirale zadane upolarnom sustavu te je stoga u uvodu najprije ukratko objašnjen polarni sustav. Usredišnjem dijelu rada obrazloženo je svojstvo logaritamske spirale koja sve svojeradijalne zrake siječe pod istim konstantnim kutom.

Nihon Kikai Gakkai ronbunshu, 2022 To improve robot manipulability, force sensing for scissors is expected to be significant. In general scissors, the moment and the crossing angle of the blade depends on the cutting position, resulting in the difference of the required input force for ...

The Elliptic Logarithmic Spiral [PDF]
Nature, 1922 I AM much obliged to Mr. Wright for his correction (NATURE, July 8, p. 40). I had made a search in English and Continental books on curves and concluded that this spiral had been overlooked as a curve. But it appears to have been recognised in connexion with the spherical pendulum. Prof. Lamb in his “Dynamics,” p.

Frontiers in Energy Research, 2022 Accurate forecasting of an electric load is vital in the effective management of a power system, especially in flourishing regions. A new hybrid model called logarithmic spiral firefly algorithm-support vector regression (LS-FA-SVR) is proposed to ...

Ultralight Scalars and Spiral Galaxies [PDF]
, 2001 We study some possible astrophysical implications of a very weakly coupled ultralight dilaton-type scalar field. Such a field may develop an (approximately stable) network of domain walls.

A “Logarithmic Spiral” in the Brain: Images of an Intracranial Dermoid Cyst
Brain Science Advances, 2016 A logarithmic spiral is a self-similar spiral curve, which often appears in nature, e.g., mollusk shells. In the normal tissues of the human body, the cochlea is also an approximate logarithmic spiral. However, approximate logarithmic spirals are rarely,

Dynamics of an Invincible Troop Formation in Ancient Open Battlefields [PDF]
Interdisciplinary Description of Complex Systems, 2021 One of the most enthralling ancient magical battle formation tactics is the Chakravyuh -- a multilayer dynamic defensive structure, which was used in the 18-days long Kurukshetra war as described in the great Indian epic Mahabharata and in many ...
