Spatiotemporal reconstruction of list mode PET data
We describe a method for computing a continuous time estimate of tracer density using list-mode positron emission tomography data. The rate function in each voxel is modeled as an ...

An electrothermally-aware full-chip substrate temperature gradient evaluation methodology for leakage dominant technologies with
As CMOS technology scales into the nanometer regime, power dissipation and associated thermal concerns in high-performance ICs due to on-chip hot-spots and thermal gradients are b...

Error estimation in wireless sensor networks
We present an analogy between the operation of a Wireless Sensor Network and the sampling and reconstruction of a signal. We measure the impact of three factors on the quality of ...

Noncoherent compressive sensing with application to distributed radar
—We consider a multi-static radar scenario with spatially dislocated receivers that can individually extract delay information only. Furthermore, we assume that the receivers are...
