  1. 1. Laboratory starlight simulator for future space-based heterodyne interferometry

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : William Karlsson; [2023]
    Keywords : Angular resolution; Astronomy; Coherence length; Digital delay lines; Fiber optical circuit; Heterodyne interferometry; Interference; Laboratory starlight simulator; NIR light Near-Infrared ; Optical path differences; Space exploration; Starlight; Testbed environment;

    Abstract : In astronomy, interferometry by ground-based telescopes offers the greatest angular resolution. However, the Earth´s atmosphere distorts the incident wavefront from a celestial object, leading to blurring and signal loss. It also restricts the transmission of specific wavelengths within the electromagnetic spectrum. READ MORE

  2. 2. Towards a tunable, wide-band acoustic transducer operating in the quantum regime.

    University essay from KTH/Tillämpad fysik

    Author : Abel Hugot; [2022]
    Keywords : Hybrid quantum systems; Acoustics; Impedance matching; SQUIDs; Hybrida kvantsystem; Akustik; Impedansanpassning; SQUIDs.;

    Abstract : In the past decade we have seen fast development of new quantum technologies that promise to revolutionise communications and computing. Many different routes are explored to physically implement such quantum technologies. Among others, we can mention superconducting circuits, spin-based devices and photonic devices. READ MORE

  3. 3. Optimization Approaches for Feedback Delay Networks

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

    Author : Johannes Hörngren; [2022]
    Keywords : ;

    Abstract : Feedback delay networks are systems based on a set of delay lines whose outputs get fed back into each others inputs. This kind of architecture is mainly used to provide a system for artificial reverberation, that is, a system to emulate the prolonging of sound in a physical space. READ MORE

  4. 4. Evaluation of Angle of Arrival based positioning for keyless entry access control

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

    Author : Martin Englund; [2018]
    Keywords : Angle of arrival; Positioning; Keyless entry access control; Bluetooth Low Energy;

    Abstract : This thesis aims at evaluating a proposed interferometry Angle of Arrival method for Bluetooth Low Energy and investigating the feasibility of using it together with current technology in a keyless entry access control solution. The current technology is an evaluation kit from Texas Instrument that is used together with various types of antennae arranged in arrays. READ MORE

  5. 5. The effect of delay-lines on sequence recall - A study of B-RAAM

    University essay from Institutionen för kommunikation och information

    Author : Timea Eriksson; [2005]
    Keywords : Long-term dependencies; primacy effect; delay-lines; B-RAAM;

    Abstract : Connectionist models have been criticized for not being able to form compositional representations of recursive data structures such as trees and lists, a matter that has been addressed by models as Elman networks, RAAM and B-RAAM. These architectures seem to have common features with the human short-term memory regarding recall. READ MORE
