1. Sparse Array Synthesis of Complex Antenna Elements
Sammanfattning : Arrays of antennas can significantly improve the performances and extend the capabilities of single-element antennas. However, antenna arrays are expensive solutions and therefore it is critical to keep the costs to a minimum. 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. Numerical and experimental modelling for wave energy arrays optimization
Sammanfattning : Many wave power conversion devices, especially point-absorbers, do not provide alone the necessary amount of converted electricity to be cost effective, instead they are designed to be deployed in arrays of many units. Such arrays, or parks, can satisfy a large-scale energy demand, reduce the costs of the produced electricity and improve the reliability of the system. LÄS MER
4. Active and Passive Unequally Spaced Reflect-Arrays and Elements of RF Integration Techniques
Sammanfattning : Using an array synthesis tool based on a modified differential evolution algorithm, it is shown that the position-phase synthesis exhibits improved pattern characteristics compared to both the phase only and position only synthesis of uniform amplitude antenna arrays. The design of an unequally spaced planar reflect-array and an active power combining reflect-array are presented. LÄS MER
5. Practical tools for the configuration of control structures
Sammanfattning : Process industries have to operate in a very competitive and globalized environment, requiring efficient and sustainable production processes. Production targets need to be translated into control objectives and are usually formulated as performance specifications of the process. LÄS MER
