1. On Specifying and Estimating Economic Growth as a Spatial Process : Convergence, Inequality, and Migration
Sammanfattning : This thesis includes three self-contained papers. The first paper considers the effect of geographically dependent observations on cross-sectional growth convergence and proposes a way of decomposing the level of technology taking into account geographical variation in growth rates.

2. Estimation Problems in Array Signal Processing, System Identification, and Radar Imagery
Sammanfattning : This thesis is concerned with parameter estimation, signal processing, and applications. In the first part, imaging using radar is considered. More specifically, two methods are presented for estimation and removal of ground-surface reflections in ground penetrating radar which otherwise hinder reliable detection of shallowly buried landmines.

3. Emission estimation based on traffic models and measurements
Sammanfattning : Traffic congestion increases travel times, but also results in higher energy usage and vehicular emissions. To evaluate the impact of traffic emissions on environment and human health, the accurate estimation of their rates and location is required. LÄS MER
4. Four-dimensional computed tomography and image processing to investigate moisture in wood
Sammanfattning : Kiln drying is the most energy-consuming operation in the industrial production of sawn timber and optimising the process is necessary to improve its efficiency. A key to achieving this is to speed up the drying, but this must not come at the cost of deteriorating the quality of the sawn timber. LÄS MER
5. Ultra-Reliable Short-Packet Communications: Fundamental Limits and Enabling Technologies
Sammanfattning : The paradigm shift from 4G to 5G communications, anticipated to enable ultra-reliable low-latency communications (URLLC), will enforce a radical change in the design of wireless communication systems. Unlike in 4G systems, where the main objective is to provide a large transmission rate, in URLLC, as implied by its name, the objective is to enable transmissions with low latency and, simultaneously, very high reliability.
