1. Non-galvanic Interconnects for Millimeter-wave Systems
Sammanfattning : Fueled by the increasing demand for higher data rates, millimeter-wave (mmW) systems emerged as a candidate that can provide multi-gigabit per second (Gb/s) transmission. This demand is mainly driven by modern communication systems and several other wireless and sensing applications such as production quality inspection and imaging systems. LÄS MER
2. Aperiodic Array Synthesis for Telecommunications
Sammanfattning : Arrays of antennas offer important advantages over single-element antennas and are thus a key part of most advanced communication systems. The majority of current arrays are based on a classical regular layout, which offer simple design criteria despite some limitations. LÄS MER
3. Taper and volume equations for poplar trees growing on farmland in Sweden
Sammanfattning : Effective management of poplar plantations for high yield production would be facilitated by the availability of improved equations for predicting the taper and volume of poplar stems. Therefore, this thesis is based upon a polynomial stem taper equation and two volume equations constructed for individual poplar trees growing on farmland. LÄS MER
4. Statistical modeling and design in forestry : The case of single tree models
Sammanfattning : Forest quantification methods have evolved from a simple graphical approach to complex regression models with stochastic structural components. Currently, mixed effects models methodology is receiving attention in the forestry literature. LÄS MER
5. Empirical models for estimating volume and biomass of poplars on farmland in Sweden
Sammanfattning : There is growing interest in establishing short-rotation poplar plantations in Sweden, primarily as a future feedstock for bioenergy. Cost-efficient planning and effective management of these plantations would be greatly facilitated by robust equations for estimating the taper, volume and height of poplar trees, and the biomass of poplar stumps and roots.
