Radiation force on relativistic jets in active galactic nuclei [PDF]

, 1999
Radiative deceleration of relativistic jets in active galactic nuclei as the result of inverse Compton scattering of soft photons from accretion discs is discussed.

Reconstruction and deceleration-acceleration transitions in modified gravity [PDF]

, 2010
We discuss the cosmological reconstruction in modified Gauss-Bonnet and F(R) gravities. Two alternative representations of the action (with and without auxiliary scalar) are considered.

Deceleration of a supersonic beam of SrF molecules to 120 m/s [PDF]

, 2016
We report on the deceleration of a beam of SrF molecules from 290 to 120~m/s. Following supersonic expansion, the molecules in the $X^2\Sigma$ ($v=0$, $N=1$) low-field seeking states are trapped by the moving potential wells of a traveling-wave Stark ...

Numerical Simulations of Shock Wave-Driven Jets [PDF]

, 2007
We present the results of numerical simulations of shock wave-driven jets in the solar atmosphere. The dependence of observable quantities like maximum velocity and deceleration on parameters such as the period and amplitude of initial disturbances and ...

Cold SO_2 molecules by Stark deceleration [PDF]

, 2007
We produce SO_2 molecules with a centre of mass velocity near zero using a Stark decelerator. Since the initial kinetic energy of the supersonic SO_2 molecular beam is high, and the removed kinetic energy per stage is small, 326 deceleration stages are ...

Assessment of the possibility of shortening the landing distance of maneuverable aircraft

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2023
The problem of implementing the landing of a maneuverable aircraft by a pilot on an undamaged section of a runway of minimum length is considered. A method of landing the aircraft is proposed, including movement along the landing glide path with minimum ...

Traveling-wave deceleration of SrF molecules [PDF]

, 2014
We report on the production, deceleration and detection of a SrF molecular beam. The molecules are captured from a supersonic expansion and are decelerated in the X$^2\Sigma^+ (v=0, N=1)$ state.

Slow Down! Digital Deceleration Towards A Socialist Social Media

tripleC: Communication, Capitalism & Critique, 2020
Hartmut Rosa argues that three systems of social acceleration (technical acceleration, the acceleration of social change and the acceleration of the pace of life) have emerged as fundamental to the human experience of late modernity.

Comparative Insights on Vehicles' Deceleration Measurements

Tehnički Glasnik
This paper investigates the possibilities of measuring vehicle deceleration using modern devices based on GPS (Global Positioning System) and MEMS (Micro Electro Mechanical System) technologies, with the aim of replacing traditional inertial devices. The
