The phase-locked loop (PLL) frequency synthesizer is a critical device of wireless transceivers. It works as a local oscillator (LO) for frequency translation and channel selection in the transceivers but suffers phase noise including reference spurs.… Contents 1 Introduction 1.1 Motivation 1.2
Minimizing fuel consumption is one of the major concerns in the aviation industry. There have been many attempts to improve the fuel efficiency of aircraft. One of the methods proposed is to vary the lift-to-drag ratio of the aircraft in different flight
The work documented in this thesis has been carried out at Ericsson Microwave Systems AB in Luleå. The company has developed a system for remote support. The system enables personnel working at Ericsson to access equipment at their customers’ sites via the
The aim of this Master Thesis is to investigate if and how acoustic signals can be used for state monitoring of operating hydro power machinery. In the past decades the manpower in Vattenfall AB’s hydro power facilities has decreased, and with that
The aim of this work was to investigate theoretically and experimentally the fact that it is possible to create sound by using the nonlinearity in air. A speaker was built verifying the theory that if at least two high frequencies at high
Close conjunction detection is the task of finding which satellites will come within a given distance of other satellites. The algorithms described here are implemented on the Connection Machine (CM) in a program called CM-COMBO. It will find close conjunctions of satellites
This research addresses the problem of modeling time-dependent traffic flow with real-time traffic sensor data for the purpose of online traffic estimation and prediction to support ATMS/ATIS in an urban transportation network. The fundamental objectives of this study are to formulate and
The central theme of this thesis is the use of imaging Surface Plasmon Resonance (iSPR) as a tool in the characterization of surfaces with laterally varying properties. Within the scope of this work, an instrument for iSPR analysis was designed and built.
The air entrained by the impact of jets ejected by plunging breakers was studied both theoretically and experimentally using laboratory plunging jets which are in horizontal relative motion with respect to the free surface. In order to investigate the influence of the
Wake-up logic is responsible for informing instructions in the Window that are waiting to execute, about the availability of their input operands. The conventional method of wake-up consumes a significant percentage of the Instruction Window energy. Reducing the wake-up energy also addresses
