Body-Taps: Authenticating Your Device Through Few Simple Taps

2018 IEEE 9th International Conference on Biometrics Theory, Applications and Systems (BTAS), 2018
To fulfill the increasing demands on authentication methods on the smart mobile and wearable devices with small form factors and constrained screen displays, we introduce a novel authentication mechanism, Body-Taps, which authenticates a device based on ...

Use of Tap Water and Disinfection Practices in Outpatient Settings: A Survey of Otolaryngologists

Archives of Otolaryngology - Head and Neck Surgery, 1991
A survey of otolaryngologists belonging to the American Academy of Otolaryngology-Head and Neck Surgery was conducted to estimate the frequency of tap water use during otologic examinations and to assess methods used for disinfection of otologic instruments in outpatient settings. Questionnaires were returned by 516 persons residing in 49 states.

The effect of set point ratio and surface Young’s modulus on maximum tapping forces in fluid tapping mode atomic force microscopy

Journal of Applied Physics, 2010
There is great interest in using proximal probe techniques to simultaneously image and measure physical properties of surfaces with nanoscale spatial resolution. In this regard, there have been recent innovations in generating time-resolved force interaction between the tip and surface during regular operation of tapping mode atomic force microscopy ...

Optimization of tap settings and capacitor units with expert system on distribution system

Proceedings of TENCON '93. IEEE Region 10 International Conference on Computers, Communications and Automation, 2002
An expert system method for discrete VAr optimization on distribution system is presented in this paper. The expert system can aid the planning engineers to make an initial feasible solution, and to decide the position of transformer tap settings and the number of capacitor units.

Line-Drop Compensator Settings for Automatic Parallel Operation of Load-Tap-Changing Transformers

Transactions of the American Institute of Electrical Engineers. Part III: Power Apparatus and Systems, 1958
From these calculations, a load voltage with an error of approximately 0.12% can be maintained at the expense of increasing the circulating current from 10.2% to 10.62%.

Method and Software Tool for Assessment of Seasonal Step-Up Transformer Optimal Tap Settings

2020
In most European countries the generators’ step-up transformers are demanded to be equipped with tap changers, explicitly or through tanϕ.-voltage requirement. Releasing the maximum available reactive power range of generator or at different voltage levels at the point of common coupling is the prime purpose of required transformers variable turns ...

Transformer Tap Setting and System Voltage Raise Impact on Optimum Planning of Static Capcitors

IEEE Transactions on Power Apparatus and Systems, 1984
Capacitor planning is based on network voltage maintenance under the normal and abnormal power system operation. The security against contingencies, the transformer tao setting and system voltage steady state operating limits together with other variables feasible range define the problem boundaries.

Probing material properties of polymeric surface layers with tapping mode AFM: Which cantilever spring constant, tapping amplitude and amplitude set point gives good image contrast and minimal surface damage?

Ultramicroscopy, 2010
A phase shift between the oscillatory motion and drive motion of an AFM-cantilever used for tapping mode AFM imaging can be related to adhesive and elastic properties of surface layers. In this study it was studied how optimal contrast between hard and soft surface layers can be achieved while minimizing the surface damage.

Optimal tap setting and VAr compensation effect on energy consumption of electrical auxiliary system of steam power plants

2002 IEEE Region 10 Conference on Computers, Communications, Control and Power Engineering. TENCOM '02. Proceedings., 2002
Reduction of energy consumption in electrical auxiliary system (EAS) of steam power plants leads to considerable energy conservation that can be fed into a network. To reach this goal, two definite suggestions i.e. tap setting of transformers and installation of reactive power compensators have been presented, and analyzed from many aspects for unit 1 ...
