1. Discerning the Receiver : A learning study with inexperienced writers aged 14-16
Abstract : The overall aim of the present study is to develop knowledge of Swedish students’ writing in English, and how teaching of a specific kind of writing can be designed and enacted. The study focuses on what the students need to discern in order to develop a more differentiated knowledge of how to adapt a message to an unknown receiver—in this case a message for a person at a hotel.

3. Reconfigurable Receiver Front-Ends for Advanced Telecommunication Technologies
Abstract : The exponential growth of converging technologies, including augmented reality, autonomous vehicles, machine-to-machine and machine-to-human interactions, biomedical and environmental sensory systems, and artificial intelligence, is driving the need for robust infrastructural systems capable of handling vast data volumes between end users and service providers. This demand has prompted a significant evolution in wireless communication, with 5G and subsequent generations requiring exponentially improved spectral and energy efficiency compared to their predecessors.
