The aim of this paper is to construct a model which decomposes a 3D image into two components: the first one containing the geometrical structure of the image, the second one containing the noise. The proposed method is based on a second order variational model and an undecimated wavelet thresholding operator. The numerical implementation is described, and(More)
In this paper, we propose a hybrid scheduling algorithm based on renewal process with the awareness of energy consumption in real-time systems. This algorithm overcomes overlapped jobs in multi-task systems by modeling time duration of jobs in a certain task as ON/OF renewal process with the consideration of energy consumption. The positive effects of this(More)
In this paper, a novel spectrum handoff scheme for cognitive ultra-wide band industrial networks (CUWBINs) is proposed, where secondary users (SUs) can access the licensed channels despite the present of primary users' signals. To maintain continuous connectivity between the cognitive users, licensed channels can be opportunistically used by an SU as long(More)
A new high porosity resorcinol-formaldehyde (RF) aerogel with improved particle necking is presented in this work. This RF aerogel was developed under CO2 supercritical drying conditions without any structural shrinkage. The water content and the catalyst percentage were varied to modify the particles' nucleation and growth mechanisms and to control(More)
