oil and gas transmission pipelines are critical items of infrastructure in providing energy sources to regions and countries. steel pipes are commonly used which can be subject to both internal and external corrosion. this paper presents an advanced nondestructive inspection technique for detection of oil-gas pipeline corrosion defect. the pulsed eddy current (pec) method has been successfully ...

Metal oxide surge arresters (ZNO) are used widely in power system to protect equipments from over voltages. Non uniform potential distribution leads to the depressed service life and low safe reliability, so grading ring is applied on HV surge arrester order to uniform the electric field distribution. One of the problems of arresters is leakage current in power frequency that different paramet...

in this paper vibration of ferromagnetic rectangular plates which are subjected to an inclined magnetic field is investigated based on classical plate theory and maxwell equations. levy type solution and finite element method using comsol software are used to obtain the frequency of the plate subjected to different boundary conditions, good agreements is obtained when computed results are compa...

The design and implementation of an FPGA core that parallelises all the necessary operations to compute the non-bonded interactions in a MD simulation with the purpose of accelarating the LAMMPS MD software is presented in this paper. Our MD processor core comprised of 4 identical pipelines working independently in parallel to evaluate the non-bonded potentials, forces and virials was implement...

Maxwell 3D of Ansoft software were used for this study. Ansoft’s solutions are based on a more general program using Maxwell’s equations. A simple analysis has been done for calculating the magnetic force interacted between two magnets of similar poles facing each other. The modeling in Anosoft has been described.

The following example compares the modelling results of a TQFP package given by the commercial tool Ansoft Maxwell Q3D and the tool Advanced Package Model provided by IC-EMC. Both software give models in terms of R, L, C lumped elements. An equivalent geometrical model is built under IC-EMC from basic mechanical data. Even if some differences exist between the geometrical models built with both...

The FPGA High Performance Computing Alliance built a 64 FPGA parallel Computer called “Maxwell” at EPCC in Edinburgh. Half of the FPGAs are from Nallatech and half from AlphaData. This poster paper presents the experience of beginning to program the Nallatech half of the machine with the Nallatech software stack, consisting of DIME-C and DIMEtalk. Also covered is the glue-layer template library...
