Nuclear Quadrupole Resonance (NQR) is a radio frequency (RF) technique that can be used to detect the presence of quadrupolar nuclei, such as the 14N nucleus prevalent in many explosives and narcotics. The technique has been hampered by low signal-to-noise ratios and is further aggravated by the presence of RF interference (RFI). To ensure accurate detection, proposed detectors should exploit the
This doctoral thesis investigates changes in the volume and character of Swedish manufacturing sector innovation output between 1970 and 2007, a time span composed of both extended periods of relative prosperity and decline. More specifically, it examines whether changes in the number of innovations, the character of the innovating firms, and the distribution of innovations across industries are g
This thesis investigates how regulatory instruments, and specifically requirements rules, targeting energy use in existing residential buildings could be made part of the forceful intervention that is required to reduce the use of energy in existing residential buildings. Two approaches to the design of requirement rules are analyzed: a detail-steering approach and a target-oriented approach. The
This paper presents a high-speed QR decomposition (QRD) processor targeting the carrier-aggregated 4 × 4 Long Term Evolution-Advanced (LTE-A) receiver. The processor provides robustness in spatially correlated channels with reduced complexity by using modifications to the Householder transform, such as decomposing-target redefinition and matrix real-valued decomposition. In terms of hardware desig
