1. 1. Method Development & Analysis of Seals using FEM

   University essay from KTH/Maskinkonstruktion

   Author : Lovisa Svanborg Östlin; [2023]
   Keywords : FEM; guidelines; hyperelastic materials; hyperelastic material models; method development; seals; FEM; riktlinjer; hyperelastiska material; hyperelastiska materialmodeller; metodutveckling; tätningar;

   Abstract : Hyperelasticity is a significant property of rubber, taken advantage of in engineering applications. A common application is the use of seals to prevent fluid transfer (liquid or gas) between solid regions. Volvo CE is often depending on external supplier when developing seals. READ MORE

3. 2. Backscatter Communications for 6G

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Lakshmi Rajeev Cheekati; Jin Yan; [2022]
   Keywords : Technology and Engineering;

   Abstract : The success of future Internet of Things (IoT) depends on, among the other things, developing energy-effcient communication techniques that can enable information exchange among billions of IoT devices with ultra-low/zero power consumption requirements. Ambient backscatter communications is an emerging technology, which utilizes the ambient Radio Frequency (RF) signal as the carrier to reduce the form-factor, and the battery requirements of low-cost small sensor type communication devices.
