   Sammanfattning : The implementation of automated systems in manufacturing industries increases efficiency, precision, and safety by reducing human intervention, errors, and waste. Variable loads can cause several problems for automation systems. LÄS MER

4. 3. Balans-en : Construction of a self-balancing robot with tilt setpoint correction

   Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Hanna Modin; Kasper Georén; [2023]
   Nyckelord :Mechatronics; two wheeled self-balancing robot; robot; inverted pendulum; control engineering; Mekatronik; tvåhjulig självbalanserande robot; robot; inverterad pendel; reglerteknik;

   Sammanfattning : This report presents the construction of a two-wheeled self balancing robot with the ability to handle an uneven load. Two-wheeled self-balancing robots have proven to be a potential solution to the problem of efficient warehouse management, thanks to their ability to navigate tight spaces quickly and efficiently while balancing their load.

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

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

   Sammanfattning : 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.

7. 5. The Sequential Sharing Problem in the Future City Logistics by the Multi - purpose Vehicles : An adaptive large neighbourhood search heuristic and formulations for the multi-depot pick-up and delivery problem with time windows, partial-recharging strategies, the fleet sizing and the mixed fleet of single-purpose vehicles and multi-purpose vehicles

   Master-uppsats, KTH/Transportplanering

   Författare :Haoye Chen; [2021]
   Nyckelord :Multi-purpose Vehicle; Sequential Sharing; Pick-up and Delivery Problem with Time Windows; Adaptive Large Neighbourhood Search; Partial Recharging Strategy; Multifunktions Fordon; Sekventiell Delning; Upphämtnings- och Leveransproblem med Tidsfönster; Anpassningsbar Stor Grannskapssökning; Partiell Laddningsstrategi;

   Sammanfattning : There are different transportations in the city logistics (e.g., passengers, freights, and wastes), which are handled respectively by single-purpose vehicles (SVs) of the corresponding type. The multi-purpose vehicle (MV) is a future concept whose load modules can be changed for different urban transportations. LÄS MER
