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

    University essay from KTH/Hälsoinformatik och logistik

    Author : Jacob Drotz; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. Parameter Stability in Additive Normal Tempered Stable Processes for Equity Derivatives

    University essay from Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

    Author : Eduardo Alberto Alcantara Martinez; [2023]
    Keywords : Parameter Stability; Lévy Processes; Calibration; Volatility Surface; Subordination; Additive Normal Tempered Stable Processes; Stable Distribution; Variance Gamma Process; Normal Inverse Gaussian Process.;

    Abstract : This thesis focuses on the parameter stability of additive normal tempered stable processes when calibrating a volatility surface. The studied processes arise as a generalization of Lévy normal tempered stable processes, and their main characteristic are their time-dependent parameters. READ MORE

  4. 3. Shear Failure of Steel Fiber and Bar Reinforced Concrete Beams Without Stirrups : Predictions based on Nonlinear Finite Element Analyses

    University essay from KTH/Betongbyggnad

    Author : David Andersson; [2022]
    Keywords : Nonlinear finite element analysis; Shear failure; Fiber reinforced concrete beams; ATENA;

    Abstract : Shear failure in concrete beams are often brittle in nature and potentially dangerous without adequatereinforcing measures. In design of concrete, it is commonly recommended to install transversalreinforcement along the shear span to induce a more ductile structural response, improving the shearcapacity all together and providing sufficient warning prior to collapse.

  5. 4. Mussels in deep water with climate change: Spatial distribution of mussel (Mytilus galloprovincialis) growth offshore in the French Mediterranean with respect to climate change scenario RCP 8.5 Long Term and Integrated Multi-Trophic Aquaculture (IMTA) using Dynamic Energy Budget (DEB) modelling

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Victoria Persson; [2022]
    Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Mediterranean; Mytilus galloprovincialis; Dynamic Energy Budget; DEB; growth rate; France; mussel cultivation; mussel farming; offshore; aquaculture; climate change; Integrated Multi-Trophic Aquaculture; IMTA; Earth and Environmental Sciences;

    Abstract : Victoria Persson Abstract Mussel cultivation is a sustainable type of food production that may help mitigate the nutritional needs of a future world population of 10-12 billion in 2100. The demand for mussels on the French market is increasing but the production is saturated due to a lack of space for expanding the cultivation close to shore. READ MORE

  6. 5. Strain rate-dependent mechanical properties of high-density polyethylene(HDPE)

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Oscar Andersson; Alexander Wiklund; [2022]
    Keywords : HDPE; strain rate; DIC; inverse calibration; Abaqus; HDPE; töjningshastighet; DIC; Inverskalibrering; Abaqus;

    Abstract : In today’s packaging industry HDPE is widely used and correct understanding of itsproperties and how to model them is of vital importance. HDPE is a semi-crystallinepolymer with a known strain rate dependence, that is a higher yield and lower strainto failure at higher strain rates. READ MORE
