6. CMOS Data Converters for Closed-Loop mmWave Transmitters
Abstract : With the increased amount of data consumed in mobile communication systems, new solutions for the infrastructure are needed. Massive multiple input multiple output (MIMO) is seen as a key enabler for providing this increased capacity. With the use of a large number of transmitters, the cost of each transmitter must be low.

7. Integrated Circuit Solutions for High Datarate Polymer Fiber Communication
Abstract : Most societies today are dependent on an Internet connection. It has to be reliable in any condition, energy efficient, but most importantly fast. High data rate communication is urgently needed, not only to connect one part of the world to the other, but also for short range applications to help us get through the day. READ MORE

8. Numerical modeling of deforming bubble transport related to cavitating hydraulic turbines
Abstract : Cavitation is a problem in many hydroelectric power plants since it can cause adverse effects on performance and damage to nearby solid surfaces. The concerns of this thesis are the numerical aspects of flow simulations in cavitating hydraulic turbines which contain several difficulties: turbulent and complex flows, steady and moving parts of the geometry, bubble transport and cavitation development.

9. High-Temperature Analog and Mixed-Signal Integrated Circuits in Bipolar Silicon Carbide Technology
Abstract : Silicon carbide (SiC) integrated circuits (ICs) can enable the emergence of robust and reliable systems, including data acquisition and on-site control for extreme environments with high temperature and high radiation such as deep earth drilling, space and aviation, electric and hybrid vehicles, and combustion engines. In particular, SiC ICs provide significant benefit by reducing power dissipation and leakage current at temperatures above 300 °C compared to the Si counterpart. READ MORE
