A promising trend in HF systems design for ocean surface mapping application is to change it from the land-based to platform-based. One of the new challenges to be faced is the motion of the platform, which will cause sampling jitter. This paper examines the effects of random jitter in sampling locations in the radar power spectrum, from which wind direction measurements are made. Random jitter leads...
The ChemCam instrument package on the Mars rover, “Curiosity”, is the first planetary instrument that employs laser-induced breakdown spectroscopy (LIBS) to determine the compositions of geological samples on another planet. However, the sampled spectra are often corrupted by various sources of interferences that would largely affect the accuracy of elemental concentration estimation. Therefore, preprocessing...
The power and energy consumed by a chip have become primary design constraints for embedded systems and are largely affected by software. However, there is a gap between software and hardware that makes it hard to predict which code consumes the least power before running it. Therefore, it is vital to discover which factors affect a program's energy consumption. In this paper we present an instruction-level...
