1. 11. Indoor Positioning and Machine Learning Algorithms

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

   Author : Raavi Uttarwar; Julián Valentín; [2021]
   Keywords : Indoor Positioning; Machine Learning; Bluetooth Low Energy; Technology and Engineering;

   Abstract : This master thesis focuses around improving the efficiency and accuracy of existing indoor positioning systems with the help of Machine Learning (ML). Our work is based on Bluetooth Low Energy (BLE) v5.1. Position estimation is currently being carried out using the Least-Squares (LS) method in the framework. READ MORE

3. 12. Wireless Power Transfer : Machine Learning Assisted Characteristics Prediction for Effective Wireless Power Transfer Systems

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

   Author : Shamsul Arefeen Al Mahmud; [2020]
   Keywords : Wireless power transfer; Machine learning; Coupling strength estimation; Load impedance estimation; Multi-transmitter wireless power transfer systems; Trådlös kraftöverföring; maskininlärning; uppskattning av kopplingsstyrka; uppskattning av belastningsimpedans; Multisändare trådlösa kraftöverföringssystem;

   Abstract : One of the main challenges in wireless power transfer (WPT) devices is performance degradation when the receiver’s position and characteristics vary. The variations in the system parameters such as load impedance and coupling strength in WPT devices affect performance characteristics such as output voltage and power. READ MORE

4. 13. Joint Estimation and Calibration for Motion Sensor

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

   Author : Peng Liu; [2020]
   Keywords : State space model; accelerometer array; parameter estimation; Maximum Likelihood; Expectation Maximization; Gradient Descent; ill-conditioned matrix.; tillståndsmodell; accelerometerarray; parameterskattning; maximimetoden; väntevärdesmaximering; gradientsökning; illakonditionerade matriser.;

   Abstract : In the thesis, a calibration method for positions of each accelerometer in an Inertial Sensor Array (IMU) sensor array is designed and implemented. In order to model the motion of the sensor array in the real world, we build up a state space model. Based on the model we use, the problem is to estimate the parameters within the state space model.

5. 14. CONSTRUCTION EQUIPMENT FUEL CONSUMPTION DURING IDLING : Characterization using multivariate data analysis at Volvo CE

   University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

   Author : Mujtaba Hassani; [2020]
   Keywords : Idling condition; environmental effect; diesel fuel; machine learning; multivariate data analysis; partial least square regression; support vector machine regression; principal component analysis; principal component regression; correlation coefficient matrix; artificial neural network; exhaust emission reduction techniques; global warming; emission regulation; CO2 estimation techniques; Gaussian process regression;

   Abstract : Human activities have increased the concentration of CO2 into the atmosphere, thus it has caused global warming. Construction equipment are semi-stationary machines and spend at least 30% of its life time during idling. The majority of the construction equipment is diesel powered and emits toxic emission into the environment. READ MORE

6. 15. A time series forecasting approach for queue wait-time prediction

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

   Author : Anton Stagge; [2020]
   Keywords : ;

   Abstract : Waiting in queues is an unavoidable part of life, and not knowing how long the wait is going to be can be a big source of anxiety. In an attempt to mitigate this, and to be able to manage their queues, companies often try to estimate wait-times. READ MORE
