Realization of energy-saving control modes on cranes of great load-carrying capacity [PDF]

, 1998
Saving energy is highly important for all types of lifting machinery. Research shows that it is possible to reduce energy consumption in mechanism drives at all stages of movement.

Dynamic analysis of the simultaneous movement of the jib lifting and crane turning mechanisms

Strength of Materials and Theory of Structures
Ефективність роботи стрілових кранів в значній мірі залежить від підвищення їхньої продуктивності при виконанні навантажувальних, розвантажувальних та монтажних операцій. Підвищення продуктивності стрілових кранів досягається за рахунок здійснення одночасної роботи окремих механізмів.

Laser‐Enabled Nanopinholes for Silicon Solar Cells with Polycrystalline Si/SiOx Passivating Contacts

Solar RRL, Volume 10, Issue 8, 27 April 2026.
Conductive nanoscale pinholes are created by selective heating of pyramid tips on randomly textured silicon via pulsed laser irradiation. Due to heat concentration at the pyramid tips, the dielectric passivating layer is selectively opened at the pyramid tips.

Leaf gas exchange measurement for steady‐state stomatal conductance model calibration

New Phytologist, Volume 250, Issue 1, Page 672-690, April 2026.
Summary Stomatal conductance models are essential components of crop and land surface models, but collecting data to calibrate them remains challenging due to large leaf‐to‐leaf variability, slow stomatal kinetics, and a lack of consistent measurement protocols, leading to unknown reliability and representativeness of calibrated model parameter ...

DESIGN AND REALIZATION OF A HAPTIC CRANE FORCE CONTROL FOR APPLICATION OF MATERIAL HANDLING BY USING ACTIVE FORCE CONTROL (AFC) [PDF]

, 2010
The final project highlights a method for controlling a haptic crane and hoist model based on an Active Force Control (AFC) strategy. It is a disturbance rejection control technique in which AFC is employed to control accurately and robustly the trolley ...

Muscle performance but not biomechanics associate with second knee injury in a matched cohort of athletes who passed functional return‐to‐sport criteria after ACL reconstruction

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 34, Issue 3, Page 1118-1130, March 2026.
Abstract Purpose Athletes remain at risk for a second knee injury after anterior cruciate ligament reconstruction (ACLR), even after passing return‐to‐sport (RTS) testing. While biomechanical asymmetries have been linked to reinjury, it is unclear whether deficits persist in athletes who meet RTS criteria.
