   Keywords : Logistics; fashion industry; hangers; single-used plastic hangers; pre-hanged clothes; sustainability; circularity;

   Abstract : In line with globalization, increased customer awareness, and increasingly stringent regulations regarding sustainability, the fashion industry faces huge challenges in line with several dimensions of sustainability. Until today, the biggest focus has been on environmental improvements linked to transportations and environmentally sustainable textiles. READ MORE

3. 12. Personalized Federated Learning for mmWave Beam Prediction Using Non-IID Sub-6 GHz Channels

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Yuan Cheng; [2022]
   Keywords : Personalized Federated Learning; Millimeter wave; Beamforming; DeepMIMO; Non-IID; Personaliserad Federad Inlärning; Millimetervågor; Strålformning; DeepMIMO; Icke-IID;

   Abstract : While it is difficult for base stations to estimate the millimeter wave (mmWave) channels and find the optimal mmWave beam for user equipments (UEs) quickly, the sub-6 GHz channels which are usually easier to obtain and more robust to blockages could be used to reduce the time before initial access and enhance the reliability of mmWave communication. Considering that the channel information is collected by a massive number of radio base stations and would be sensitive to privacy and security, Federated Learning (FL) is a match for this use case.

4. 13. Grain Size Analysis of Late Pleistocene Loess Deposits, Jersey

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Joakim Edlund; [2022]
   Keywords : Jersey; loess; grain size; ice age; past climate; Jersey; löss; kornstorlek; istid; forntida klimat;

   Abstract : As the world faces the effects of rapid climate change it is essential that we understand how the Earth’s climate has evolved in recent geological history. The island of Jersey harbours loess deposits which hold clues to recent climate change which have not been extensively studied. READ MORE

5. 14. Cross coupling in a two-axis control system for stabilized platforms

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Bill Lavebratt; [2022]
   Keywords : MIMO; Modeling; Two-axis gimbal system; Decoupler; Inner loop disturbance compensation; Control theory.;

   Abstract : Inertial stabilized platforms consisting of a two-axis gimbal assembly are often modelled as two independent SISO systems, describing the dynamics of the elevation axis and the azimuth axis respectively. In reality the state of the elevation channel and the state of the azimuth channel affect each other. READ MORE

6. 15. Adaptive Modulation Coding Scheme in Amplify and Forward Relay Networks

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Nirnay Reddy Nallavelli; Sushma Swaraj Chilupuri; [2022]
   Keywords : Adaptive Modulation; Modulation and Coding Schemes; Amplify and Forward; Signal to Noise Ratio; Nakagami-m Distribution.;

   Abstract : Wireless communications have become an essential part of our daily life. Despite the fact that wireless networks are simple to set up and deploy, the channel conditionsin wireless networks are susceptible to fading and attenuation, thereby reducing the transmission efficiency and reliability.
