1. 11. FIDUCIARY DUTY AND ESG CONSIDERATIONS – ARE THEY COMPATIBLE? A case study on institutional investors and their commitment to the Net-Zero Asset Owner Alliance

   University essay from Göteborgs universitet/Graduate School

   Author : Jenny Asplund; William Samadzadehaghdam; [2020-07-01]
   Keywords : SRI; Fiduciary duty; ESG; Institutional investors; Net-Zero Asset Owner Alliance; Shareholder engagement;

   Abstract : As a response to the issues regarding climate change, several organizations and initiatives are founded to tackle them, such as the Net-Zero Asset Owner Alliance (AOA), backed by the United Nations. The explicit goal of the institutional investors in this alliance is to decarbonize their portfolios by 2050. READ MORE

3. 12. Indoor Positioning Bluetooth Angle of Arrival

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

   Author : Mohammed M T Amer; Khadeeja Gamal Mohammed Atteya; [2020]
   Keywords : Angle of Arrival; Bluetooth Low energy; Indoor positioning; Internet of Things; Bluetooth direction finding.; Technology and Engineering;

   Abstract : In this thesis, we present the Angle of Arrival (AoA) technique to detect the direction of a source indoors using radio frequency (RF) signal. This technique estimates the direction of the incoming Bluetooth signal, using a tag as a transmitter and an array equipped with a number of antennas as a receiver. READ MORE

4. 13. Evaluation of Bluetooth 5.1 as an Indoor Positioning System

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Philip Andersson; Linus Persson; [2020]
   Keywords : Indoor Positioning System; AoA; RSSI; IMU; Sensor Fusion; Multipath Propagation; Inomhus positioneringssystem; AoA; RSSI; IMU; Sensor Fusion; Flervägsutbredning;

   Abstract : There is a high demand for Indoor Positioning Systems (IPS) due to the wide application possibilities. The main issue for localization by wireless signals in an indoor environment is the multipath propagation problem. Multipath propagation occurs when signals reflects and refract from an object, changing the signals characteristics. READ MORE

5. 14. Design of a Size Reduced Antenna Array for Angle of Arrival (AoA) Estimation for BLE 5.1

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

   Author : Felix Långberg; Jonas Thurborg; [2020]
   Keywords : Antenna; Array; Bluetooth; 5.1; Angle of arrival; optimization; Technology and Engineering;

   Abstract : Bluetooth low energy (BLE) 5.1 allows for Angle of Arrival(AoA) measurements which in turn requires antenna arrays to be used. These arrays must be low power which results in that an efficient switching pattern is applied and for greater field of view good omnidirectivity is necessary. READ MORE

6. 15. Improved Accuracy for Indoor Positioning with Bluetooth 5.1: From Theory to Measurements

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

   Author : Victor Sesma Santos; Victor Egorov; [2020]
   Keywords : Technology and Engineering;

   Abstract : In this thesis we are evaluating Bluetooth Low Energy (BLE) v5.1 in combination with Direction Of Arrival (DOA) algorithms and receiving antenna arrays for indoor positioning systems. The thesis is divided in two parts. The first part is the core of the thesis and is composed by the evaluation of DOA algorithms in a direction finding system. READ MORE
