1. Impulse noise and brain injury. An experimental study in rats
Abstract : Abstract. Pressure waves, experienced as impulse noise, affect many body organs, although most attention has been paid to the inner ear. Impulse noise is produced by e.g. READ MORE

2. Millimeter-Wave Impulse Radio
Abstract : This thesis investigates the opportunity of wireless multi-gigabit per second communication at the millimeter-wave (mmW) frequencies around 60 GHz by using impulse radio and nanoelectronics. Today most wireless communication take place in the microwave region, where several different systems and applications are crowding the narrow-band channels. READ MORE

3. Assessment of experimental neurotrauma
Abstract : Model systems of closed head injury are designed to replicate aspects of traumatic brain injury, ischemia and epilepsy in man. The aim of this thesis was to (1) develop sensitive systems enabling analyses of the biochemical reactions, as reflected by leakage of marker compounds to the cerebrospinal fluid (CSF); and (2) develop and assess a new model for closed head injury and associated dynamic changes in the brain cell.

4. Sub-Nyquist Sampling Impulse Radio UWB Receivers for the Internet-of-Things
Abstract : In the era of Internet-of-Things, the demand for short range wireless links featured by low-power and low-cost, robust communication and high-precision positioning is growing rapidly. Impulse Radio Ultra-Wideband (IR-UWB) technology characterized by the transmission of sub-nanosecond pulses spanning up to several GHz band with extremely low power spectral density emerges as a promising candidate.
