  1. 1. LSTM-attack on polyalphabetic cyphers with known plaintext : Case study on the Hagelin C-38 and Siemens and Halske T52

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

    Author : Oriol Closa; [2023]
    Keywords : ;

    Abstract : Polyalphabetic cyphers have been used for centuries and well into the 1970s to transmit all kinds of messages. Since then, computers and modern cryptography have taken over making bruteforce attacks unfeasible when designed properly. READ MORE

    Abstract : To meet the aims of the Paris climate agreement, it is necessary to reduce energy use in buildings. Efficient HVAC systems are a critical part in achieving a low delivered energy use. READ MORE

  6. 5. 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
