Energy Efficient and Reliable ARQ Scheme (ER-ACK) for Mission Critical M2M/IoT Services [PDF]

open access: yes, 2014
Wireless sensor networks (WSNs) are the main infrastructure for machine to machine (M2M) and Internet of thing (IoT). Since various sophisticated M2M/IoT services have their own quality-of-service (QoS) requirements, reliable data transmission in WSNs is

Medicare 1971: Changing Attitudes and Changing Legislation [PDF]

open access: yes, 1970
Bone conduction (BC) is the way sound energy is transmitted by the skull bones to the cochlea causing a sound perception. Even if the BC sound transmission involves several pathways including sound pressure induced in the ear canal, inertial forces ...

Solving the Time-Varying Inverse Kinematics Problem for the Da Vinci Surgical Robot

open access: yesApplied Sciences, 2019
A dialytic-elimination and Newton-iteration based quasi-analytic inverse kinematics approach is proposed for the 6 degree of freedom (DOF) active slave manipulator in the Da Vinci surgical robot and other similar systems. First, the transformation matrix-

Statistics and control of waves in disordered media

open access: yes, 2015
Fundamental concepts in the quasi-one-dimensional geometry of disordered wires and random waveguides in which ideas of scaling and the transmission matrix were first introduced are reviewed.

Research on transmission control method of tension tower hydraulic tension device based on PLC

open access: yesJournal of Applied Science and Engineering, 2023
Using the traditional method to control the transmission process of the tension tower hydraulic tightening device, there is a problem of slow speed step response in the range of device operating speed from 12km/h to 32km/h.

Non-universal transmission phase behaviour of a large quantum dot

open access: yes, 2017
The electron wave function experiences a phase modification at coherent transmission through a quantum dot. This transmission phase undergoes a characteristic shift of $\pi$ when scanning through a Coulomb-blockade resonance.

Vibrationally Mediated Control of Single Electron Transmission in Weakly Coupled Molecule-Metal Junctions [PDF]

open access: yes, 2010
We propose a mechanism which allows one to control the transmission of single electrons through a molecular junction. The principle utilizes the emergence of transmission sidebands when molecular vibrational modes are coupled to the electronic state ...

Transmissibility and transmission of respiratory viruses [PDF]

open access: yesNature Reviews Microbiology, 2021
Human respiratory virus infections lead to a spectrum of respiratory symptoms and disease severity, contributing to substantial morbidity, mortality and economic losses worldwide, as seen in the COVID-19 pandemic. Belonging to diverse families, respiratory viruses differ in how easy they spread (transmissibility) and the mechanism (modes) of ...

Generation principle and meshing characteristics of conjugate-curve circular arc gears

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2015
The generation principle and meshing characteristics of conjugate-curve circular arc gears, which is proposed based on the theory of conjugate curves, are studied in this paper.

Transmission statistics and focusing in single disordered samples

open access: yes, 2013
We show in microwave experiments and random matrix calculations that in samples with a large number of channels the statistics of transmission for different incident channels relative to the average transmission is determined by a single parameter, the ...
