  1. 1. Active stabilisation of a micro-sized fibre cavity using tilt locking to enable quantum operations on single ions

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Jannek Hansen; [2021]
    Keywords : Quantum computation; optical cavity; microcavity; locking; tilt locking; cavity stabilization; Gaussian-Hermitian modes; quantum computer; higher-order transverse modes; Physics and Astronomy;

    Abstract : In this thesis, the tilt locking scheme is applied to create an error signal that monitors length changes in a fibre-based microcavity. To find a robust and precise locking technique is an essential step towards quantum operations on single rare-earth ions doped in microcrystals. Quantum computing and information is a frontier of modern physics. READ MORE

  2. 2. Boost your spare parts supply - A case study on cooperation terms in the spare parts supply chain focused on the supplier-buyer dyad

    University essay from Lunds universitet/Teknisk logistik

    Author : Måns Krantz; Anders Fasth Gillstedt; [2021]
    Keywords : Purchasing; After-Sales; Spare Parts; Supply Chain Management; Supplier Collaboration; Consignment Stock Strategy; Technology and Engineering;

    Abstract : Purchasing has become an increasingly important function in manufacturing companies, as it accounts for a large extent of total spending and influences a company's competitive position. It is relevant for Tetra Pak, a global manufacturer of packaging and processing solutions, active since the 1950s. Tetra Pak has over 100. READ MORE

  3. 3. Tipping Markets : An analysis of the Commission's proposal for a Digital Markets Act

    University essay from Uppsala universitet/Juridiska institutionen

    Author : Hedvig Sylwan; [2021]
    Keywords : ;

    Abstract : The particular characteristics and practices of digital platforms have given rise to the phenomenon of “tipping”, where one platform provider takes the whole market. There has been a growing concern among competition law regulators and enforcers that the traditional ex-post antitrust instruments cannot remedy the distortion of competition it causes in digital markets.

  4. 4. Investigation on how presentation attack detection can be used to increase security for face recognition as biometric identification : Improvements on traditional locking system

    University essay from Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Author : Fredrik Öberg; [2021]
    Keywords : Face Recognition; Presentation Attacks; Convolutional Neural Network;

    Abstract : Biometric identification has already been applied to society today, as today’s mobile phones use fingerprints and other methods like iris and the face itself. With growth for technologies like computer vision, the Internet of Things, Artificial Intelligence, The use of face recognition as a biometric identification on ordinary doors has become increasingly common.

  5. 5. Improving image quality of a streak camera using periodic shadowing

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : David-Gabriel Lange; [2021]
    Keywords : combustion physics; laser; lock-in amplification; laser induced fluorescence; periodic shadowing; Rhodamine B; streak camera; Mode-locking; microfluidics; fluorescence lifetime imaging; Physics and Astronomy;

    Abstract : Stray light suppression using a method inspired by lock-in amplification, called periodic shadowing, is examined and demonstrated for a measurement involving a streak camera. The experiment consists of resolving the fluorescent decay of the dye Rhodamine B (RhB) and examining both the rise and the decay of the fluorescence. READ MORE
