The paper presents a completely analytical formula to determine the phase back emf of a slotted BLDC motor with interior or exterior rotor and parallel or radial permanent magnet (PM) magnetization and concentrated winding. The formula is based on integrat ...
We question the global universe isotropy by probing the alignment of local structures in the cosmic microwave background (CMB) radiation. The original method proposed relies on a steerable wavelet decomposition of the CMB signal on the sphere. The analysis ...
The reliability of new overhead electric and telecommunication lines depends principally on the quality of their support structures. These structures are generally made of wood, metal or concrete. The complexity of a natural substance such as wood requires ...
This paper reviews the application of a novel methodology for analysing the isotropy of the universe by probing the alignment of local structures in the CMB. The strength of the proposed methodology relies on the steerable wavelet filtering of the CMB sign ...
The crystallisation of soluble sulphate salts is one of the most important factors of stone monument degradation. The origin of these salts is variable: Marine, air pollution, building or restoration material. The lack of certainty about these sources repr ...
Apparatus for retaining magnetic particles within a segment of a flow-through cell during flow of a fluid through the cell. The apparatus comprises (a) an electrical current source (12) (b) an electromagnet (13) having a winding (14) connected to the curre ...
