(2019-09-01)The influence of Fe-alloying on the structural transition temperatures, microstructure, and mechanical and magnetocaloric properties of polycrystalline Ni41Co9−xFexMn40Sn10 (at. %) (x = 0–3) alloys has been studied. The ... -
Enhanced magnetocaloric effect in rapidly solidified HoNi2 melt-spun ribbons
(2019-02-05)The structural, magnetic and magnetocaloric properties of HoNi2 melt-spun ribbons were investigated by X-ray diffraction, magnetization and specific heat measurements. The as-solidified ribbons samples produced are single ... -
Giant low-field magnetocaloric effect in Si alloyed Ni-Co-Mn-In alloys
(2019-01-15)For NiMn-based Heusler alloys, simultaneously achieving high magnetization difference and low thermal hysteresis across the magnetostructural transformation is of crucial importance to obtain large low-field actuated ... -
Critical magnetic and magnetocaloric behavior of amorphous melt-extracted Gd50(Co69.25Fe4.25Si13B13.5)50 microwires
(2019-07)We report on the structural, magnetic, and magnetocaloric properties and critical behavior of high-quality amorphous melt-extracted Gd50(Co69.25Fe4.25Si13B13.5)50 alloy microwires with an average diameter of 42 μm. The ... -
Tuning the reversible magnetocaloric effect in Ni-Mn-In based alloys through Co and Cu co-doping
(2019-03-01)The reversibility of the giant magnetocaloric effect (MCE) through the magnetic field–induced magnetostructural transformation in Ni–Mn–In‐based alloys is a key issue towards the potential magnetic refrigeration applications. ... -
Magnetic properties of GaAs:Mn self-assembled nanostructures grown at relatively high-temperature by Molecular Beam Epitaxy
(2019-04-01)We report the influence of the Mn atomic concentration (at.%) on the nanostructures formation and magnetic properties of GaAs:Mn layers grown by Molecular Beam Epitaxy at a relatively high substrate temperature of 530 °C ... -
Application of IoT with haptics interface in the smart manufacturing industry
(2019-05-01)The emerging technologies that make up Industry 4.0, include the Internet of Things and big data. The haptic interfaces have been used in different industries, but apparently, they are not integrated with the two technologies ... -
Dissimilarity-Based Linear Models for Corporate Bankruptcy Prediction
(2019-03-01)Bankruptcy prediction has acquired great relevance for financial institutions due to the complexity of global economies and the growing number of corporate failures, especially since the world financial crisis of 2008. In ... -
Seat Occupancy Detection Based on a Low-Power Microcontroller and a Single FSR
(2019-02-08)This paper proposes a microcontroller-based measurement system to detect and confirm the presence of a subject in a chair. The system relies on a single Force Sensing Resistor (FSR), which is arranged in the seat of the ... -
Hesitant Fuzzy Linguistic Term and TOPSIS to Assess Lean Performance
(2019-02-28)Manufacturing companies usually expect strategic improvements to focus on reducing both waste and variability in processes, whereas markets demand greater flexibility and low product costs. To deal with this issue, lean ... -
Calidad bacteriológica del agua en zonas marginadas de Ciudad Juárez, México, que carecen de agua potable entubada
(2018-01-01)En Ciudad Juárez el 12% de la población no cuenta con un suministro de agua apropiado, siendo el abastecimiento a base de pipas o directamente del pozo sin desinfectar los principales y únicos medios. Es por esto, que ... -
Zariski topology for multiplication modules with applications to frames, quantales and classical Krull dimension
(2019-09-01)For a multiplication R-module M we consider the Zariski topology in the set Spec (M) of prime submodules of M. We investigate the relationship between the algebraic properties of the submodules of M and the topological ... -
