Three-dimensional numerical simulations of the atmospheric flow on giant planets using the primitive equations show that shallow thermal forcing confined to pressures near the cloud tops can produce deep zonal winds from the tropopause all the way down to the bottom of the atmosphere. These deep winds can attain speeds comparable to the zonal jet speeds within the shallow, forced layer; they ar...

An inexpensive yet portable device for calibrating four different flow meters in the undergraduate fluid mechanics laboratory was designed and constructed. The apparatus contains a rotameter, a turbine-type meter, a venturi meter, and an orifice meter. All four meters are calibrated simultaneously using a volumetric measuring tank. Results obtained by undergraduate students are presented, and a...

Weight function distributions for an electromagnetic flow meter with a non-insulating pipe are numerically simulated and verified. The weight function distribution is very important for solution of flow velocity of distribution. In this paper, a finite element method (FEM) is used for solving the weight function distribution for this novel electromagnetic flow meter. First of all, a numerical s...

We analyze the scepticism on the hydrodynamic turbulence in Keplerian astrophysical disks expressed in Balbus and Hawley 2006 and show the failure of arguments of the paper. Recently Balbus and Hawley 2006 (BH06) have shown time-dependent three-dimensional nonlinear wave solution when considering a local Keplerian flow. Authors have demonstrated that the linear wave solution derived in Johnson ...

The paper describes the functioning of the measuring system of a wave thermoanemometer. The effect of the application of a thermal wave induced by forcing quasirandom signals (PRBS) is also discussed. Correlation analysis of signals generated in the receiving wires of the thermoanemometric sensor is presented.

A 5-megacycle Doppler flow meter, calibrated in-vitro, was found to give a linear response to blood flow in the ranges commonly encountered in haemodialysis. With this, blood flow through artificial kidneys could be measured simply and with a clinically acceptable error. The method is safe, as blood lines do not have to be punctured or disconnected and hence there is no risk of introducing infe...

Simple Network Management Protocol version 3 is an extension of earlier versions addressing security and administration features of SNMP. SNMPv3 has additional features like different message format and defines new management information bases (MIB) for security, configuration, notification, view-based access control and proxy forwarding. Simulation of SNMPv3 traffic flow meter MIB has been car...

A mass smart meter roll-out represents a vast challenge concerning the performing of the corresponding installation processes. Starting from the hypothesis that meter operators would be able to successfully implement a mass smart meter roll-out in Germany under the current conditions, we show that a determined lack of process support by information and communication technology (ICT) indicates t...
