1. Developing a portable, customizable, single-channel EEG device for homecare and validating it against a commercial EEG device
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : There are several commercial electroencephalography (EEG) devices on the market; however, affordable devices are not versatile for diverse research applications. The purpose of this project was to investigate how to develop a low-cost, portable, single-channel EEG system for a research institute that could be used for neurofeedback-related applications in homecare.

2. Development of a QRNG front-end for shot noise measurement : analysis of quantum shot noise originating from photodiodes
University essay from Linköpings universitet/InformationskodningAbstract : As one of the more mature quantum technologies, quantum random number generators (QRNGs) fill an important role in producing secure and private keys for use in cryptogra- phy in e.g. quantum key distribution (QKD) systems. Many available QRNGs are expen- sive and optical QRNGs often require complex optical setups. READ MORE

5. A Modular Approach to Design and Implementation of an Active GNSS Antenna
University essay from Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakultetenAbstract : This masters thesis describes the design, implementation and testing of an active antenna intended for use with global navigation satellite systems. The active antenna is composed of two major parts, a dual-band circular patch antenna and a dual-band low-noise amplifier. To streamline the design process, a modular solution was adopted. READ MORE
