  1. 1. Quantum Optical Description of High-order Harmonic Generation

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Isabel Moreno; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : High-order Harmonic Generation (HHG) is a highly non-linear process in which an atom interacts with a strong laser field. The laser field lowers the atomic potential barrier allowing bound electrons to escape into the continuum through tunnel ionization, propagate, and, with some probability, recombine with the parent ion.

  3. 2. IMPLICATION FOR THE UNIVERSITY OF GOTHENBURG TO ALIGN WITH THE GOVERNMENT’S TARGET REGARDING CLIMATE NEUTRALITY BY 2045 - Scenarios and Consequences

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Nafiseh Kazemi Ashtiani; [2023-06-21]
    Nyckelord :Climate Neutrality; GHG emissions; higher education institutions HEIs ; Net Zero emission; carbon footprint; carbon capture and storage CCS ;

    Sammanfattning : It is widely acknowledged that one of the most significant global challenges of the 21 st century is climate change. In its Fifth Assessment Report (2014), the Intergovernmental Panel on Climate Change (IPCC) described the present extent of the problem and the hazards involved, citing greenhouse gas emissions from human activities as the primary contributor to global warming since the mid-20th century.

  4. 3. A Multi-Level Perspective: Construction and Demolition Waste Management System : Case Study: Bengaluru

    Master-uppsats, Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Författare :Prashanth Ramakrishna; [2023]
    Nyckelord :Bengaluru; C D Waste Management; MLP Theory; Path Dependency;

    Sammanfattning : A significant proportion of construction and demolition (C&D) waste is encompassed within the broader category of global waste. The handling of C&D waste is subject to the influence of a tripartite of environmental, social, and economic factors. LÄS MER

  5. 4. Tyst stad : En studie om god ljudmiljö och blandstad vid planeringen av högljudda kulturaktiviteter

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för fysisk planering

    Författare :Martin Wallenius Kral; [2023]
    Nyckelord :soundscape; environmental noise; figure-ground; hi-fi; lo-fi; ljud; stadsplanering; planering; fysisk planering; buller; blandstad; kulturaktiviteter;

    Sammanfattning : I Stockholm pratades det om klubbdöden under 2019 eftersom flera högljudda kulturaktiviteter behövt stänga i innerstaden. Den huvudsakliga anledningen var konflikter mellan boende och kulturaktiviteter om bullerstörningar som naturligt uppstår när människor ska bo, verka och leva i en tät blandstadsmiljö. LÄS MER

  7. 5. Digital Front End Algorithms for Sub-Band Full Duplex

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Midhat Rizvi; Khaled Al-Khateeb; [2023]
    Nyckelord :Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

    Sammanfattning : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.
