6. Structural sound transmission and attenuation in lightweight structures
Abstract : Everyone wants a peaceful and quiet home, but in noisy cities it is a challenge to create such homes. New building techniques are mostly introduced for other purposes than noise control -- stability, economy, heat transfer and so on. READ MORE

7. Lightweight Authentication in Wireless Networks
Abstract : In this thesis, we develop and analyse two novel authentication protocols well suited for wireless devices. iven that wireless devices have limited resources such as processing power, bandwidth, storage, and energy, the proposed authentication protocols need to be lightweight. READ MORE

8. Thermodynamic and kinetic investigation of systems related to lightweight steels
Abstract : Lightweight steels have attracted considerable interest for automobile applications due to the weight reduction without loss of high strength and with retained excellent plasticity. In austenitic Fe-Mn-Al-C steels, the nano-precipitation of the κ-carbide within the austenitic matrix significantly contributes to the increase in yield strength. READ MORE

9. Light-weighting Methodology in Rail Vehicle Design through Introduction of Load Carrying Sandwich Panels
Abstract : Lightweight design in rail vehicles has been important for quite some time. Structures have been optimised to fulfill their purpose and cut unnecessary weight to reach allowable axle loads. Classically this is done by using steel, thin-walled structures, throughout the car body, or, alternatively, power-pressed aluminum profiles. READ MORE

10. Design, processing and properties of lightweight foams from cellulose nanofibers
Abstract : Foams are applied in many areas including thermal insulation of buildings, flotation devices, packaging, filters for water purification, CO2 sorbents and for biomedical devices. Today, the market is dominated by foams produced from synthetic, non-renewable polymers, which raises serious concerns for the sustainable and ecological development of our society. READ MORE
