Most of steel structures in Japanese harbors are becoming older, the maintenance is one of big problems in our society. As one of anti-corrosion methods for steel structures in seawater, there is a process using electro-deposition of calcareous coating by impression of electric current ... En savoir plus
An approach to the development of the higher order theories of beams, rods, plates and shells have been proposed in our previous publications. It is based on series expansion of the corresponding field equations in term of the cross-section coordinates. The proposed approach is general ... En savoir plus
High precision ‘designer’ magnetic fields are needed for the latest generation of particle physics experiments, such as the search for the Electric Dipole Moment of the neutron. The shift in focus from the high energy frontier to precision measurements of these small quantities will ... En savoir plus
CT and MRI are current techniques used for stroke detection. Although they are favored for their high accuracy and resolution, there are many situations that a potable and low-cost imaging technique is required. Ultra-sound technique is portable, but it cannot be used for stroke ... En savoir plus
This paper presents a new design methodology of quasi-conformal transformation optics (QCTO) based modified Luneburg lens antennas using a broadband anti-reflective (AR) layer. The design used QCTO technique to modify portion of the lens’s spherical geometry into a flat surface for ... En savoir plus
Photothermal deflection spectroscopy (PDS) relies on the angular displacement of a probe beam through a fluid with varying index of refraction. The precise angular displacement of the probe beam is dependent on the entire index of refraction field, which is in turn dependent on fluid ... En savoir plus
Deep geological repositories (DGRs) are currently being proposed in several countries to deal with the nuclear waste. The safe long-term disposal of the waste is guaranteed by a multi-barrier system, which includes a natural barrier (host rocks) and an engineered barrier system. Large ... En savoir plus
This paper studies external corrosion of an underground transmission pipeline carrying natural gas. Pitting corrosion and Stress Corrosion Cracking (SCC) are two most common external corrosion types for buried pipelines and they usually happen when the mitigation methods such as coating ...

This paper proposes a solution method using piezoelectric sensors to detect an anomaly, such as a deformation caused by a crack or fracture, in a pipeline. COMSOL Multiphysics, a simulation software, is used to induce anomalies of different magnitudes to a pipe and record the data from ... En savoir plus
The present study aimed to determine the effect of nanofluid concentration, channel inclusion, flow rate, and heat flux, on the thermal effectiveness of Al2O3 nanofluid and 6061-T6 aluminum foam metal with 91% porosity and 40 linear pores per inch as components in a heat exchange system ...
