Design and Analytical Evaluation of a New Self-Centering Connection with Bolted T-Stub Devices

open access: yesAdvances in Materials Science and Engineering, 2013
A new posttensioned T-stub connection (PTTC) for earthquake resistant steel moment resisting frames (MRFs) is introduced. The proposed connection consists of high strength posttensioned (PT) strands and bolted T-stubs.

Self-positioning ability of a sphericon-shaped magnetic millirobot rolling on an inclined surface

open access: yesAIP Advances, 2018
This paper introduces the novel self-positioning ability of a sphericon-shaped magnetic millirobot (SSMM) on an inclined surface. The SSMM is comprised of four identical half cones with a cylindrical magnet inserted into the geometric center, and it can ...

The Role of Biomaterials as Angiogenic Modulators of Spinal Cord Injury: Mimetics of the Spinal Cord, Cell and Angiogenic Factor Delivery Agents

open access: yesFrontiers in Pharmacology, 2018
Spinal cord injury (SCI) represents an extremely debilitating condition for which no efficacious treatment is available. One of the main contributors to the inhospitable environment found in SCI is the vascular disruption that happens at the moment of ...

Siła Krytyczna Ramienia Dźwigu przy Wyboczeniu z Płaszczyzny Zawieszenia

open access: yesEngineering Transactions, 1967
The usual method for computing the critical force of a bar with luffing rope for buckling out of the plane of suspension was, until recently, the same as for a bar fixed at its lower end the upper end remaining free.

Redundancy Resolution and Robust Control of Underwater Vehicle-Manipulator Systems with Minimizing Restoring Moment

open access: yesJournal of Institute of Control, Robotics and Systems, 2009
In this paper, redundancy resolution of UVMS (underwater vehicle-manipulate. system) is addressed. In general, UVMS has redundant DOFs (degrees of freedom) as many as DOFs of manipulator and these redundant DOFs can be used to optimize the configuration of UVMS while satisfying given tasks. We propose a performance index for redundancy resolution which

“Long-term stability of stimulating spiral nerve cuff electrodes on human peripheral nerves”

open access: yesJournal of NeuroEngineering and Rehabilitation, 2017
Background Electrical stimulation of the peripheral nerves has been shown to be effective in restoring sensory and motor functions in the lower and upper extremities. This neural stimulation can be applied via non-penetrating spiral nerve cuff electrodes,

Turkey's regional powerhood within regional (in)security complex: Transformation from a conflict-ridden environment into a security community [PDF]

open access: yesJournal of Regional Security, 2015
Many optimists believed that the 'Arab Spring' was a ripe moment for regional radiant Turkey with its pro-active stance that could trigger 'demonstrative effect' and transform the conflict-ridden Middle Eastern (in) security complex into a pluralistic ...
