Mathematical Model of Speeds Change Device on the Basis of Switched Differential Mechanisms
International Applied Mechanics, 2019The geometry and kinematics of a dynamic system with several degrees of freedom and controllable friction clutches are considered. The necessary kinematic transmission ratio between the input and output links is obtained using the friction clutches. The model uses a smooth approximation of the discontinuous function of the moment of friction.

A new mechanism for negative differential resistance (NDR) originating from local orbital symmetry matching between an electrode and a molecule in a single molecular electronic device is proposed and demonstrated by a joint experimental and theoretical scanning tunneling microscope study of a cobalt phthalocyanines (CoPc) molecule on a gold substrate ...

Privacy-Preservation Mechanisms for Smart Energy Metering Devices Based on Differential Privacy
2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW), 2019This paper investigates the application of differential privacy to the Smart Grid. Due to the nature of the Smart Grid, data drawn from it can be used to predict individuals behaviours and actions inside their homes which is a huge privacy violation. We show an attack that is able to predict behaviour with up to 94.3% precision.

Tethered robots often experience entangling of their cables with obstacles in uncertain disaster environments. This paper proposes a spherical tether handling device that unfastens a robot's tether during surveys by releasing the tether and carrying it aside.

2015 International Symposium on Micro-NanoMechatronics and Human Science (MHS), 2015
The present study was designed to investigate the effect of the uniaxial mechanical strain on the proliferation and differentiation of mouse mesenchymal stem D1 cells seeded into the octacalcium phosphate (OCP)/ Gelatin (Gel) composite in vitro. The mechanical stimulation with a uniaxial loading device was analyzed by finite element analysis in order ...

A tunneling injection mechanism into the channel of a modulation doping field effect transistor is discussed. In the presaturation regime of the drain current, the source current exhibits negative differential resistance as a result of the charge control by the gate field in the channel.

The drug release pattern of micronized ethynodiol diacetate from silicone devices was thoroughly investigated in polyethylene glycol-containing elution media with a wide range of solubility and partition properties. When high drug solubility was maintained, the drug release pattern followed a Q - t1/2 relationship (matrix controlled). Under this matrix-

LVAD+Pulsatility immediately post-OHT, with partial attenuation of this difference by 6 months, and normalization by 12 months post-OHT. Conclusion: Aortic stiffness is markedly increased immediately post-OHT among patients bridged with CF-LVADs, with attenuation of this increased stiffness over the first year after transplant.
