  1. 1. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Svante Rosenlind; [2023]
    Nyckelord :Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

    Sammanfattning : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. LÄS MER

  3. 2. RBC with Endogenous Health

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Författare :Linnéa Ekberg; Rasmus Grehn; [2023]
    Nyckelord :Business cycle; Health; Health investment; Time allocation;

    Sammanfattning : The purpose of this paper is to contribute to the limited literature on RBC models with endogenous health accumulation. To this end, we develop an infinitely lived agent model with endogenous health, productivity shocks, and health shocks. Health is conceptualized as a capital stock in accordance with the Grossman model. LÄS MER

  4. 3. Ray-tracing Based Investigations on the Deployment of RISs in Indoor Scenarios

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

    Författare :Swaroop Divya Sai Prem Nambala; Dexin Kong; [2023]
    Nyckelord :Reconfigurable intelligent surface; RIS; optimization; Ray-tracing; Mixed integer linear programming MILP ; Complex impulse response; Wireless Insite.; Technology and Engineering;

    Sammanfattning : Reconfigurable intelligence surface (RIS) is a promising candidate technology for future 6G wireless communication systems. In existing communication systems, the network operators are unable to control the propagation environment, which causes significant limitations on communication performance. LÄS MER

  5. 4. High Level Synthesis for ASIC and FPGA

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

    Författare :Malin Heyden; [2023]
    Nyckelord :HLS; high level synthesis; asic; fpga; catapult; filter; sfir; Technology and Engineering;

    Sammanfattning : This thesis aims to evaluate the performance of Siemens’ High Level Synthesis (HLS) tool Catapult. HLS can be considered the next step up in abstraction level from writing traditional Register Transfer Level (RTL) code which is time consuming and error prone. LÄS MER

  7. 5. Development of GNSS Type Processing for the Characterization of the Mobile Propagation Channel

    Master-uppsats, KTH/Fastigheter och byggande

    Författare :Adrien Bardou; [2021]
    Nyckelord :LMS Channel; Multi-paths; GNSS; SCHUN; Simulation; LMS-kanal; flerv¨agar; GNSS; SCHUN; Simulering;

    Sammanfattning : Mobile communication systems are undergoing significant development on increasingly wide frequency bands (5G in particular). To support this development, a detailed characterization of the propagation of electromagnetic waves in L, S and C band between a station (satellite, airborne or ground) and a mobile platform is necessary to analyze and model the phenomena that have a decisive impact on the performance, availability and operability of systems.
