Subharmonic solutions of a nonconvex noncoercive hamiltonian system

, 2003
In this paper we study the existence of subharmonic solutions of the Hamiltonian system Jẋ+ u∗∇G(t, u(x)) = e(t) where u is a linear map, G is a C1-function and e is a continuous ...

Ambient Pressure Sensitivity of Subharmonic Vibrating Single Microbubbles [PDF]

Objective: The response of ultrasound contrast agents is sensitive to ambient pressure, especially via their scattered subharmonic signal, which makes them a promising candidate for non-invasive pressure measurements in vivo.

Generalized Lindelöf Finiteness Conditions for the λ-Type of a Subharmonic Function

, 2002
Встановлено критерій скінченності λ-типу субгармонійної функції. У випадку, коли λ(r) = rᵖ L(r), ρ ∊ N , де L — повільно змінна функція, цей критерій збігається з критерієм Ліндельофа.We establish a finiteness criterion for the λ-type of a subharmonic ...

Subharmonic mixer design

, 2001
This graduate project report contains a presentation of a design of an X-band subharmonic mixer using two non-biased Schottky diodes in an antiparallel configuration as non-linear devices to produce harmonics for the mixing function. A computer simulator

Minimal subharmonic functions and related integral representations

A Choquet-type integral representation result for non-negative subharmonic functions of a one-dimensional regular diffusion is established. The representation allows in particular an integral equation for strictly positive subharmonic functions that is ...
