  1. 6. Customer churn prediction in a slow fashion e-commerce context : An analysis of the effect of static data in customer churn prediction

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

    Author : Luca Colasanti; [2023]
    Keywords : Survival Analysis; Time To Event prediction; Churn retention; Machine Learning; Deep Learning; Customer Clustering; E-commerce; Analisi di sopravvivenza; Previsione del tempo a evento; Ritenzione dall’abbandono dei clienti; Apprendimento automatico; Apprendimento profondo; Segmentazione della clientela; Commercio elettronico; Överlevnadsanalys; Tid till händelseförutsägelse; Churn Prediction; Maskininlärning; Djuplärning; Kundkluster; E-handel;

    Abstract : Survival analysis is a subfield of statistics where the goal is to analyse and model the data where the outcome is the time until the occurrence of an event of interest. Because of the intrinsic temporal nature of the analysis, the employment of more recently developed sequential models (Recurrent Neural Network (RNN) and Long Short Term Memory (LSTM)) has been paired with the use of dynamic temporal features, in contrast with the past reliance on static ones.

  3. 7. Assisted GNSS Positioning using State Space Corrections

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Oskar Philipsson; [2023]
    Keywords : positioning; GNSS; SSR; EKF; sensor fusion;

    Abstract : Classical GNSS based positioning has accuracy limitations due to many sources oferror. The error sources range from clock errors and orbit errors toerrors due to variations in atmospheric propagation delays. One way to improve GNSSpositioning is to generate real time corrections using a GNSS reference network. READ MORE

  4. 8. Automated High-Temperature Pressure Sensor Verification and Characterization

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Algirdas Bartkevicius; [2023]
    Keywords : Pressure sensor; sensor verification; sensor characterization; piezoelectric sensor; dynamic pressure sensor;

    Abstract : Gas turbines are widely used in power generation. Monitoring pressure variations in the combustion chamber allows for real-time assessment of the turbines performance, and can be used to optimize combustion processes, leading to reduced emissions. READ MORE

  5. 9. Machinability study on GCI brake discs - Effects of material variations and process behavior on tool life

    University essay from Lunds universitet/Industriell Produktion

    Author : Christian Jaunviksna; [2023]
    Keywords : Metal cutting Machinability Grey cast iron Tool wear Cutting data Hardness Microstructure Segmentation; Technology and Engineering;

    Abstract : Grey cast iron is one of the most used materials in the automotive industry. The material has a range of properties that makes it suitable for machining applications, but manufacturers still experience machinability problems. READ MORE

  6. 10. Dynamic Warning Signals and Time Lag Analysis for Seepage Prediction in Hydropower Dams : A Case Study of a Swedish Hydropower Plant

    University essay from Uppsala universitet/Datalogi

    Author : Lovisa Olsson; Julia Hellström; [2023]
    Keywords : hydropower; dam safety; dam monitoring; seepage; prediction models; data-driven methods; artificial intelligence; AI;  linear regression; Support Vector Regression; SVR; Long Short-Term Memory; LSTM;

    Abstract : Hydropower is an important energy source since it is fossil-free, renewable, and controllable. Characteristics that become especially important as the reliance on intermittent energy sources increases. However, the dams for the hydropower plants are also associated with large risks as a dam failure could have fatal consequences. READ MORE
