  1. 1. Micromagnetic study of spin Hall nano-oscillator arrays and their synchronization dynamics

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

    Författare :Ari Sigurdsson; [2020]
    Nyckelord :spintronics; spin Hall nano-oscillators; spin wave; synchronization; micromagnetic modelling.; spinntronik; spinn-Hall nano-oscillatorer; spinn wave; synkronisering; mikromagnetisk modellering.;

    Sammanfattning : Spintronics is the study of electron spins and their utilization in electronic devices. Within this field, spin-based oscillators have shown promise for mi- crowave signal generation as they can operate at high frequencies, are small in scale and are compatible with modern fabrication techniques.

  2. 2. Radiation effects on wide bandgap semiconductor devices

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Patric Elf; [2020]
    Nyckelord :applied physics;

    Sammanfattning : Gallium nitride (GaN) based high-electron-mobility transistors (HEMTs) are used in a wide variety of areas, such as 5G, automotive, aeronautics/astronautics and sensing elds ranging from chemical, mechanical, biological to optical applications. Owing superior material properties, the GaN based HEMTs are especially useful in harsh operation environments e. LÄS MER

  3. 3. Numerical and experimental investigations of gas jet used in atomisation of metal powders

    Master-uppsats, KTH/Materialvetenskap

    Författare :Arun Kamalasekaran; [2020]
    Nyckelord :;

    Sammanfattning : The environmental impact caused by the traditional production techniques has led to increased research in the field of alternative production techniques such as additive manufacturing. However, the environmental sustainability of the manufacturing techniques that produce and supply powders to the additive manufacturing process can be improved significantly. LÄS MER

  4. 4. Design and Development of an Experimental Test Rig for Heat Sinks

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Gabriel Kaduvinal Abraham; [2020]
    Nyckelord :Cooling; Experimental Setup; Flow rate; Heat sink; Plumbing; Sensors; Thermal Efficiency; Kylning; experimentell installation; flödeshastighet; kylfläns; VVS; sensorer; värmeeffektivitet;

    Sammanfattning : Heat sinks are used mainly to take away the excessive heat which are produced in a component. This transfer of heat enables a smooth operation of the system with the heat generating component. The efficiency of heat sink is often dependent on the amount of heat it can take away within the smallest duration of time. LÄS MER

  5. 5. Comparative Life Cycle Assessment of Cardiac Monitoring Devices : A Case Study

    Master-uppsats, KTH/Industriell produktion

    Författare :Samruddha Kokare; [2020]
    Nyckelord :Life Cycle Assessment LCA ; Cardiac monitoring devices; Stretchable electronics; Livscykelbedömning LCA ; hjärtövervakningsanordningar; stretchbar elektronik;

    Sammanfattning : Current cardiac monitoring devices are rigid, bulky, and integrate poorly with the human skin, obstructing health monitoring for longer periods. With the miniaturization of electronics, soft and stretchable polymer substrate-based cardiac monitoring device is being developed at Mycronic AB to overcome the aforementioned issues and replacing the traditional rigid electronics-based cardiac monitoring devices.
