Control of the radiative heating of a glass plate

Luc Paquet

In a preceding paper (MSIA, 2012), we have studied the radiative heating of an infinite horizontal glass plate. Here, we want to control the temperature T(x, t) at time t along the flat glass thickness x during the fixed time of heating ] 0 , tf[ , by acting on the temperature u(t) of the black…

Homological projective duality for determinantal varieties

Marcello Bernardara, Michele Bolognesi, Daniele Faenzi

In this paper we prove Homological Projective Duality for categorical resolutions of several classes of linear determinantal varieties. By this we mean varieties that are cut out by the minors of a given rank of a matrix of linear forms on a given projective space. As applications, we obtain pairs…

Lossless error estimates for the stationary phase method with applications to propagation features for the Schrödinger equation

Felix Ali Mehmeti, Florent Dewez

We consider a version of the stationary phase method in one dimension of A. Erdelyi, allowing the phase to have stationary points of non-integer order and the amplitude to have integrable singularities. After having completed the original proof and improved the error estimate in the case of regular…

Synthesis of nanosized TiO2 powder by sol gel method at low temperature

W. Nachit, Samira Touhtouh, Zahra Ramzi, Mohamed Zbair, Adil Eddiai, Mohamed Rguiti, Abdelhadi Bouchikhi, Abdelowahed Hajjaji, Khalil Benkhouja

Nanotechnology is all about making products from very small constituents, components or subsystems to gain greatly enhanced material properties and functionality. Nanocrystalline anatase TiO2 was prepared by a facile sol–gel route at a temperature of 50°C under mild conditions. Titanium…

Dielectric characterization of lead zirconate-titane/polyurethane thin film composite: Volume fraction, frequency and temperature dependence

Sarah Aboubakr, Mohamed Rguiti, Madiha Yessari, Abdessamad Elballouti, Christian Courtois, Abdelowahed Hajjaji

The Lead Zirconate-titane (PZT) ceramic is known by its piezoelectric characteristic, but also by its stiffness. The use of a composite based on a polyurethane (PU) matrix charged by a piezoelectric material, enable to generate a large deformation of the material, therefore harvesting more energy.…

Elaboration and characterization of BZT lead-free ceramic prepared in chemical way and with the addition of a sintering aid (LBCU)

Madiha Yessari, Abdelowahed Hajjaji, Mohamed Rguiti, Sarah Aboubakr, A. Arbaoui

The Barium Titanates are very promising materials ecologically, but still have poor piezoelectric properties compared to the Lead Zirconate Titanates. So in order to improve them, a substitution of the zirconium in our ceramic (BT) has been investigated by X-ray diffraction (XRD) and grain size…
