  1. 1. Evaluation and Optimization of LTE-V2X Mode 4 under Aperiodic Messages of Variable Size

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

    Author : Md Mamunur Rashid; [2023]
    Keywords : LTE-V2X; aperiodic; variable size; CAM; Technology and Engineering;

    Abstract : Vehicular networks connect vehicles for improved road safety and efficiency with the assistance of wireless information exchange. Vehicular networks are based on the frequent broadcast of awareness messages referred to as CAM (Cooperative Awareness Messages) or BSM (Basic Safety Message) in the ETSI and SAE standards, respectively.

    Abstract : The importance of accurately controlling the speed and torque of Synchronous Machines (SMs) in industry, transportation, aerospace, to name a few, can not be overstated. The driving unit to control the machines are called Variable Speed Drives (VSDs) and they can be designed in many different ways. READ MORE

  5. 4. Kalman-Filter Design and Evaluation for PMSM Rotor-Temperature Estimation

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Daniel Mårtensson; [2022]
    Keywords : Technology and Engineering;

    Abstract : The permanent magnet synchronous motor, PMSM, is an efficient electrical motor that has seen a greater prevalence in the automotive industry from the increasing demand for electrical vehicles. Managing the temperature of the permanent magnet rotor is important to optimize motor utilization and avoid hardware failures. READ MORE

  6. 5. Automatic analysis of tool status in band saws

    University essay from Umeå universitet/Institutionen för fysik

    Author : Axel Östman; [2022]
    Keywords : ;

    Abstract : The products with the highest return and longest life cycle in the sawmill industry are boards and planks. Unfortunately, a large part of the log becomes bi-products during the cutting process. One way to reduce the amount of bi-products in a sawline is to saw with as thin kerfs as possible. That is the cut of the blade. READ MORE
