  1. 1. Approach for frequency response-calibration for microphone arrays

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Jacob Drotz; [2023]
    Nyckelord :microphone array; frequency response; calibration; sine sweep; inverse filter; digital signal processing DSP ; convolution; Fast Fourier Transform FFT ; Discrete Fourier Transform DFT ; acoustic measurements; audio engineering; mikrofonarray; frekvenssvar; kalibrering; sinussvep; inverterat filter; digital signalbehandling; faltning; Fast Fourier Transform FFT ; Discrete Fourier Transform DFT ; akustiska mätningar; ljudteknik;

    Sammanfattning : Matched frequency responses are a fundamental starting point for a variety ofimplementations for microphone arrays. In this report, two methods for frequencyresponse-calibration of a pre-assembled microphone array are presented andevaluated. LÄS MER

  3. 2. Assessment and evaluation of heterogeneity in data from immune infiltration spatial niches in lung cancer

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Mahta Keivani Najafabadi; [2023]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : The protein biomarker expressions in three types of sampled immune INFILTration spatial niches in lung cancer tissue were measured using the new technology Digital Spatial Profiler (DSP). The three types of immune INFILTration that were observed in lung tumors were STROMA identified as immune cells separate from tumor cells, Tertiary lymphoid structures (TLS) identified as dense structures of organized immune cells and finally Infiltraterate where immune cells dispersed among and in direct contact with tumor cells (INFILT).

  4. 3. Filtering Pressure Oscillations in a Common Rail Pressure Signal with IIR Notch Filters for Injected Fuel Amount Estimation

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Marcus Akkila; Denis Ramsden; [2023]
    Nyckelord :DSP; Water hammer effect; IIR; Common-rail; Injected fuel amount estimation; Notch filter; Water hammer effect; IIR; Digital signalbehandling; Injektionsmängd; Common-rail; bandstoppfilter;

    Sammanfattning : This project concerns an inline six-cylinder (I6) diesel truck engine equipped with common-rail injection system. It has been done at the Swedish truck manufacturer Scania CV AB. The main focus is digital signal processing of the rail pressure sensor signal from the injection system. LÄS MER

  5. 4. The Impact of Management Control Systems on Diversification Strategy Processes : A Study of Diversified Firms

    Magister-uppsats, Uppsala universitet/Företagsekonomiska institutionen

    Författare :Kira Östlund; Naomi Akafare Akelmu; [2023]
    Nyckelord :Management Control Systems MCS ; Belief Controls; Interactive Controls; Boundary Controls; Diagnostic Controls; Diversification Strategy Processes DSP ; Initiation Stage; Searching Stage; Execution Stage;

    Sammanfattning : Purpose: The purpose of this research is to examine how Management Control Systems (MCS) impact Diversification Strategy Processes (DSP) in diversified firms. Method: A qualitative research method was used where five different profiled managers participated in the research. LÄS MER

  7. 5. Development of an embedded system platform for signal analysis and processing

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Philip Lind; [2023]
    Nyckelord :Digital signal processing; DSP; digital filter; FIR; IIR; Butterworth; Chebychev; windowed sinc; Digital signalbehandling; DSP; digitalt filter; FIR; IIR; Butterworth; Chebychev; sinc; fönstermetoder;

    Sammanfattning : Information is often stored and transmitted through electrical signals. This information may need refinement, which may be done by processing and altering the electrical signals, in which it is transmitted. When refining a signal, a frequency selective filter is often used. It can be implemented through digital signal processing (DSP). LÄS MER
