Parallel analysis of axial pressing, casting and PIM as routes for production of alnico8
(European Powder Metallurgy Association (EPMA), 2010)
Samples of Alnico8 were prepared from the same starting powder by pressing, casting and powder injection moulding (PIM), respectively, and characterized by SEM and thermal analysis-DTA/TGA. Optimization of the sintering ...
Sintered strontium hexaferrite shaped by injection moulding in unidirectional magnetic and electromagnetic field
(European Powder Metallurgy Association (EPMA), 2010)
Strontium hexaferrite permanent magnets were produced by powder injection molding (PIM). The feedstock for powder injection molding was prepared by mixing strontium hexaferrite powder with a "Solvent system" organic binder. ...
A detailed XRD and FTIR analysis of Bi2O3 doped ZnO-SnO2 ceramics
(A Global Road Map for Ceramic Materials and Technologies: Forecasting the Future of Ceramics, Intern, 2008)
ZnO-SnO2 ceramics were prepared with a traditional powder mixed oxide route by mixing starting powders of ZnO and SnO2 in the molar ratio 2:1 and adding small amounts (0.5; 1.0; and 1.5 molar%) of Bi 2O3. These mixtures ...
Novel uniaxial anemometer containing NTC thick film segmented thermistors
(IEEE, New York, 2008)
A novel uniaxial anemometer was created using a NTC thick film segmented therinistor to measure wind speed and direction. The anemometer operated on the principle of heat loss caused by the air volume flow and air speed. ...
Differential balanced symmetrical T-type LC for EMI chip filters and their EM simulation
(IEEE, New York, 2008)
This paper presents the newly developed differential balanced symmetrical T-type LC EMI chip filters. Initially, two different types of T-type LC filters, produced by multilayer green sheet technology, were characterized ...
Characterization of the structure and magnetic properties of Fe49Co2V made by the powder metal injection molding route
(Advances in Powder Metallurgy and Particulate Materials - 2010, Proceedings of the 2010 Internationa, 2010)
The semi-hard magnetic alloy Fe49Co2V is widely used in electronics and automation. Many of these parts are complex ones which can be produced with significant advantages by the PIM technology. In this work the feedstock ...
Spectral and fractal analysis of biosignals and coloured noise
(IEEE, New York, 2007)
The amplitude power spectra and fractal dimensions of surrogate data designed as coloured noise were compared with spectra and FDs of biosignals in order to improve the tools for brain activity analysis. It is interesting ...
Multipolar anisotropy and domain semicircular alignment in sintered strontium hexaferrite shaped by PIM technology
(European Powder Metallurgy Association (EPMA), 2012)
Multipolar anisotropy was induced in strontium hexaferrite green samples in a high intensity magnetic field during feedstock injection by PIM (powder injection molding) technology. Strontium hexaferrite particles in the ...
Fuzzy logic point of view applied to diseases caused by dynamic mutations
(12th IEEE International Symposium on Computational Intelligence and Informatics, CINTI 2011 - Procee, 2011)
For the first time, this paper tries to explain the origins of diseases caused by unstable DNA repeats, known as dynamic mutations. It is common to find fairly simplified correlation between the number of DNA repeats and ...
Low frequency noise characteristics of BaTiO3-NiFe2O4 composites at phase transition
(Institute of Electrical and Electronics Engineers Inc., 2015)
In this work we present detailed investigation of low frequency noise characteristics of BaTiO3-NiFe2O4 ceramic composites of different percentage of NiFe2O4. At the particular temperatures (that gets under the broad maximum ...
