  1. 11. Modelling and Control of an Extruder Cooling System

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Christopher Fritzon; Nils Persson; [2021]
    Keywords : Technology and Engineering;

    Abstract : The thesis aims to develop knowledge of the physics and thermodynamics behind a nonlinearity in an air cooling system for an plastic extruder machine. To accomplish this, both nonlinear and linearized models were set up in Matlab and Simulink environments based on the laws of physics and thermodynamics. READ MORE

  3. 12. Numerical study of the effect of thermal ice loads on concrete dams

    University essay from KTH/Betongbyggnad

    Author : Imal Zuwak; Wasseem Kordoghly; [2020]
    Keywords : Arch dam; Buttress dam; Concrete; Finite element analysis; Ice load; Valvdamm; Lamelldamm; Betong; Finit elementanalys; Islast;

    Abstract : It is essential to understand the mechanics of ice load and how it affects concrete dams located in a cold climate, such as Sweden, where the temperature becomes sufficiently cold to freeze the surface of the reservoir. The purpose of this thesis is to study ice load distribution along concrete dams, and its response during the application of an ice load. READ MORE

  4. 13. Modelling of passive intermodulation in RF systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Martin Petek; [2020]
    Keywords : ;

    Abstract : Modern communication systems are increasing in complexity, power and dynamicrange. As a result, weaker signals can be detected which improves rangeand quality of service. However, this also results in greater sensitivity to spurioussignals which can impact system performance. READ MORE

  5. 14. Detection of Human Emotion from Noise Speech

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Sai Chandra Sekhar Reddy Nallamilli; Nihanth Kandi; [2020]
    Keywords : Neural Network; Activation Function; Fast Fourier Transform; Karhunen-Loeve Transform; speech enhancement; filtering; Wavelet Transform; Speech preprocessing; signal to noise ratio; shallow neural network;

    Abstract : Detection of a human emotion from human speech is always a challenging task. Factors like intonation, pitch, and loudness of signal vary from different human voice. So, it's important to know the exact pitch, intonation and loudness of a speech for making it a challenging task for detection. READ MORE

  6. 15. Predicting runners’ oxygen consumption on flat terrain using accelerometer data

    University essay from KTH/Matematisk statistik

    Author : Kevin Olsson; Valeriy Ivinskiy; [2019]
    Keywords : Bachelor Thesis; Prediciting oxygen consumption; Accelerometer; Fitness technology; Kandidatexamensarbete; Prediktion av syrekonsumtion; Accelerometer; Träningselektronik;

    Abstract : This project aimed to use accelerometer data and KPIs to predict the oxygen consumption of runners’ during exercises on flat terrain. Based on many studies researching the relationship between oxygen consumption and running economy and a small set of data, a model was constructed which had a prediction accuracy of 81.1% on one individual.
