In this article, we prove Malinnikova’s result for Weinstein operator as follows: Let \({(ɸ_n)}_{n=1}^∞\) be an orthonormal basis for \(L_α^2 (R_+^d )\). If the sequences \({(e_n)}_{n=1}^∞⊂R_+^d\) and \({(a_n)}_{n=1}^∞⊂R_+^d\) are bound

The aim of this paper is to prove new variations of uncertainty principles for Weinstein operator. The first of these results is variation of Heisenberg-type in equality for Weinstein transform that is for s>0. Then, there exists a constant C(α,s),

Using harmonic analysis associated with the Weinstein operator on R+d ΔW=∑j=1d∂2∂xj2+2α+1xd∂∂xd,α>−12, we study the associated Poisson semigroup. Next, in this context, we study the Littlewood–Paley function denoted gα(f). Especiall

The aim of this paper is to prove new uncertainty principles for the Weinstein operator. The first of these results is a sharp Heisenberg-type inequality for the Weinstein transform, that is, for s≥1 and f∈Lα2(R+d), ‖|x|sf‖Lα2(R+d)‖|ξ|sF

This paper presents fast test protocols for ageing IGBT modules in power cycling conditions, and a monitoring device that tracks the on-state voltage V CE and junction temperature T J of IGBTs during ageing test operations. This device is implemented

This paper describes a part of a larger supervision system able to monitor the on-state voltage VCE and the junction temperature TJ of IGBT in operation. That system is associated to an ageing test bench stressing IGBT modules by power cycling. All a
