Quasi Free 238U (e,e'f)-Cross Section in Macroscopic-Microscopic Approach [PDF]

, 2002
We present the result of a theoretical study of inclusive quasi free electrofission of $^{238}$U. The off-shell $ $cross sections for the quasi free reaction stage have been calculated within the Plane Wave Impulse Approximation (PWIA), using a ...

Asymptotic estimation of some multiple integrals and the electromagnetic deuteron form factors at high momentum transfer

, 2007
A theorem about asymptotic estimation of multiple integral of a special type is proved for the case when the integrand peaks at the integration domain bound, but not at a point of extremum.

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Assessing safety conditions in underground excavations after a methane-air mixture explosion [PDF]

E3S Web of Conferences, 2019
A technique for evaluation of shock wave impulse after a methane-air mixture explosion is elaborated. The numerical model developed in previous studies has been verified in the laboratory by using laser initiation of explosives and measuring the pressure

Mechanical systems subjected to generalized nonholonomic constraints

, 2000
We study mechanical systems subject to constraint functions that can be dependent at some points and independent at the rest. Such systems are modelled by means of generalized codistributions.

On angled bounce-off impact of a drop impinging on a flowing soap film [PDF]

, 2017
Small drops impinging angularly on thin flowing soap films frequently demonstrate the rare emergence of bulk elastic effects working in-tandem with the more common-place hydrodynamic interactions. Three collision regimes are observable: (a) drop piercing

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

Advanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,
