ABOUT THE APPROACH TO THE DETERMINATION OF CERTAIN KINEMATIC PARAMETERS OF THE CAR’S MOVEMENT ON THE HUMP BRAKING POSITIONS OF MARSHALLING YARDS

International Journal of Advanced Studies, 2018
In the design of marshalling hump, the choice of optimal parameters of great importance to have accurate values of the kinematic parameters of the movement of the cars, uncoupling at all parts.

Confinement‐Induced Nonlocality and Optical Nonlinearity of Transdimensional Titanium Nitride Films in the Epsilon‐Near‐Zero Region

Advanced Optical Materials, EarlyView.
The epsilon‐near‐zero (ENZ) effect in metals emerges only in nanometer‐scale films with exceptional optical quality. Titanium nitride (TiN) films grown by molecular beam epitaxy retain high crystallinity down to 2 nm and exhibit dramatically enhanced nonlinear optical responses near the ENZ region.

The Effect of Speed Humps on Highways Pavement Condition [PDF]

International Journal of Engineering, 2020
Speed humps used as a tool of traffic calming technique that applied to force drivers to reduce their vehicle’ speeds at some locations. For developed countries, the implementations of speed humps are often used within residential areas as well as at locations of schools crossing.  For developing countries (e.g.

Public Evaluation of Speed Humps Performance and Effectiveness [PDF]

Civil Engineering Journal, 2018
In Egypt, it is believed that speed humps are the cheapest and best solutions to reduce vehicles speed and thus reduce the number of potential accidents. Due to the lack of specifications in Egypt that govern the installation of speed humps, they were spread randomly and with different dimensions without adequate studies.

3D‐Printing Aided Rapid Prototyping of Pretensioned Tensegrity Structures for Robotic Applications

Advanced Robotics Research, EarlyView.
Printing, injection molding, and assembly (PMA) is a method for rapid prototyping mesoscale, topologically complex, and tensioned tensegrity structures. In combination with PMA method, two mold design strategies: modular mold and compact channel layout, enable efficiency and scalability for tensegrity fabrication.

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

Advanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

An example of calculating time, speed and brake way of the car on the site of the second braking position at the hump yard under the influence of small crosswinds

Вестник Научно-исследовательского института железнодорожного транспорта, 2016
To present day the speed of sliding car in the theory of calculation of marshaling hump determined by the formula of free falling body, where the acceleration of free falling bodies are given with the inertia of the wheelsets, which is unacceptable ...

Cyclic Mechanical Loading of Cardiomyocytes via Pressure‐Driven Non‐Planar Membrane Deformation in a Bioreactor System

Advanced Science, EarlyView.
In this research article, Mansoor and coworkers present a novel device that applies controlled mechanical stimuli to cardiomyocytes using pressure‐driven membrane deformation. By exposing cells to physiologically and pathologically relevant loading conditions, the platform reproduces distinct structural, functional and molecular responses associated ...

Hair Follicle Seedling Cryomicroneedles from Hierarchical Microfluidic Organoid on a Chip

Advanced Science, EarlyView.
In this paper, a hierarchical microfluidic chip is developed to produce uniform hair follicle organoids (HFOs) in cryomicroneedles. Cryopreservation agents encapsulate HFOs, preserving viability and hair growth potential. The cryomicroneedles enable simple intradermal transplantation with good skin penetration.

Perception Based Level of Service for Speed Humps in Mixed Traffic Conditions - a Case Study in India

Communications
Speed humps are used to reduce vehicle speeds and enhance the road safety. However, there has been very limited study that discusses the Level of Service (LOS) that a speed hump provides to its road users.
