1. Generation, Modulation, and Detection of Signals in Microwave Photonic Systems
Sammanfattning : This thesis deals with the use of photonic technology in microwave and millimeter-wave applications. The two major parts of this work have been techniques for transmission and signal generation. LÄS MER
2. Millimeter-Wave Photonics: Signal Sources and Transmission Links
Sammanfattning : With the use of higher and higher frequencies in a number of current and future wireless millimeter-wave applications it is beneficial to use photonics for several reasons. The use of optical fibers is an advantageous way to transport millimeter-waves in terms of loss, mechanical flexibility, weight, and insensitivity to electromagnetic interference. LÄS MER
3. Critical features and impacts of mathematics teacher professional development programs : Comparing and characterizing programs implemented at scale
Sammanfattning : The aim of this thesis is to contribute to the knowledge base on conceptualizations and impacts of teacher professional development (PD) programs. This is done by studying the case of two large-scale teacher PD programs. LÄS MER
4. Supporting instructional improvement at scale : The role of teacher professional development programs and mathematics curriculum materials
Sammanfattning : We are currently witnessing an increase of international interest in mathematics education, fueled partly by the growing concerns of students’ declining results, but also by changed perceptions of what mathematics students should master. In response, many initiatives have appeared in order to move away from traditional to more inquiry based approaches to teaching. LÄS MER
5. Working out work : from personal informatics to redesigning work
Sammanfattning : "Personal Informatics" (PI) and "Quantified Self" (QS) are two contemporary notions in the field of Human–Computer Interaction. Such hardware and software systems gather personalized quantified data and visualize them for the purpose of supporting self-reflection. LÄS MER
