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.

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.

The observed spiral structure of the Milky Way [PDF]
, 2014 The spiral structure of the Milky Way is not yet well determined. The keys to understanding this structure are to increase the number of reliable spiral tracers and to determine their distances as accurately as possible.

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 ...

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,

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.

Design and Investigation of an Asymmetric Logarithmic Spiral Gear Drive
Applied Bionics and Biomechanics, 2022 Sliding on gear teeth working surfaces has negative effects on the performances of gears, such as tooth surface wear, pitting, etc. In order to reduce the gear sliding during high speed and heavy load, a new type of pure rolling gear, named as an ...
