On a New Discrete SEIADR Model with Mixed Controls: Study of Its Properties
(MDPI, 2018-12-25)
A new discrete SEIADR epidemic model is built based on previous continuous models. The model considers two extra subpopulation, namely, asymptomatic and lying corpses on the usual SEIR models. It can be of potential interest ...
Some Formal Results on Positivity, Stability, and Endemic Steady-State Attainability Based on Linear Algebraic Tools for a Class of Epidemic Models with Eventual Incommensurate Delays
(Hindawi, 2019-07-08)
A formal description of typical compartmental epidemic models obtained is presented by splitting the state into an infective substate, or infective compartment, and a noninfective substate, or noninfective compartment. A ...
Nanostructured giant magneto-impedance multilayers deposited onto flexible substrates for low pressure sensing
(Springer, 2012-04)
Nanostructured FeNi-based multilayers are very suitable for use as magnetic sensors using the giant magneto-impedance effect. New fields of application can be opened with these materials deposited onto flexible substrates. ...
On a New Epidemic Model with Asymptomatic and Dead-Infective Subpopulations with Feedback Controls Useful for Ebola Disease
(Hindawi Publishing Corporation, 2017-02-19)
This paper studies the nonnegativity and local and global stability properties of the solutions of a newly proposed SEIADR model which incorporates asymptomatic and dead-infective subpopulations into the standard SEIR model ...
Magnetocaloric Effect Caused by Paramagnetic Austenite–Ferromagnetic Martensite Phase Transformation
(MDPI, 2018-12-21)
In the present work, the magnetization of Ni50Mn17.5Ga25Cu7.5 alloy undergoing the first-order phase transition from paramagnetic austenite to ferromagnetic martensite was measured to evaluate the magnetic-field-induced ...
Metallic Glass/PVDF Magnetoelectric Laminates for Resonant Sensors and Actuators: A Review
(MDPI, 2017-05-31)
Among magnetoelectric (ME) heterostructures, ME laminates of the type Metglas-like/PVDF (magnetostrictive+piezoelectric constituents) have shown the highest induced ME voltages, usually detected at the magnetoelastic ...
Sensor Applications of Soft Magnetic Materials Based on Magneto-Impedance, Magneto-Elastic Resonance and Magneto-Electricity
(MDPI, 2014-04-25)
The outstanding properties of selected soft magnetic materials make them successful candidates for building high performance sensors. In this paper we present our recent work regarding different sensing technologies based ...
Enhanced mass sensitivity in novel magnetoelastic resonators geometries for advanced detection systems
(Elsevier, 2019-10-01)
Acoustic wave based sensors have a major impact in the detection of low concentration of biological and chemical agents. Magnetoelastic resonator platforms are particularly interesting due to their low cost and wireless ...
Exchange biased FeNi/FeMn bilayers with coercivity and switching field enhanced by FeMn surface oxidation
(AIP Publishing, 2013-09)
FeNi/FeMn bilayers were grown in a magnetic field and subjected to heat treatments at temperatures of 50 to 350 degrees C in vacuum or in a gas mixture containing oxygen. In the as-deposited state, the hysteresis loop of ...
Size Dependence of the Magnetoelastic Properties of Metallic Glasses for Actuation Applications
(MDPI, 2019-10-04)
We present an exhaustive study of the magnetoelastic properties of 24 strips with different rectangular dimensions, cut from a long ribbon of Metglas((R)) 2826MB3. The strips have a length-to-width ratio R = L/w ranging ...
