  1. 1. Time-based Key for Coverless Audio Steganography: A Proposed Behavioral Method to Increase Capacity

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : John Alanko Öberg; Carl Svensson; [2023]
    Keywords : Coverless audio steganography; information hiding; covert communication; effective capacity; behavioral; Täcklös ljudsteganografi; informationsdöljning; hemlig kommunikation; effektiv kapacitet; beteendemässig;

    Abstract : Background. Coverless steganography is a relatively unexplored area of steganography where the message is not embedded into a cover media. Instead the message is derived from one or several properties already existing in the carrier media. This renders steganalysis methods used for traditional steganography useless. READ MORE

  3. 2. EV battery temperature estimation : Designing a model for minimal temperature of high-voltage battery in a BEV

    University essay from Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)

    Author : Björn Arvidsson; [2023]
    Keywords : BEV; temperature estimation; lowpass filter; BEV; lågpassfilter; temperaturestimering;

    Abstract : Fordonsindustrin är inne i ett skifte, där förbränningsmotorer (ICE) bör-jar fasas ut och det satsas mer på eldrift med hjälp av batterier (BEV).  I detta arbete, som efterfrågades av Volvo Cars, utvecklades en matema-tisk modell som uppskattar den lägsta temperaturen i en elbils högspän-ningsbatteri.

  4. 3. Exercise Classification with Machine Learning

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Joel Ekstrand; [2023]
    Keywords : Machine learning; signal processing; noise reduction; feature extraction; exercise classification; machine learning; signalprocessering; brusreducering; feature extraction; rörelseklassificering;

    Abstract : Innowearable AB has developed a product called Inno-XTM that calculates musclefatigue during three exercises: squat jumps, wall sit, and leg extension. Inno-X uses an accelerometer and a surface electromyography sensor. READ MORE

  5. 4. Adaptive Cruise Control and Platooning With Tire Slip Awareness

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

    Author : Filip Henriksson; Gustaf Reimer; [2022]
    Keywords : Platooning; tire slip; car following; C-ACC; autonomous driving;

    Abstract : Platooning is a method where a chain of vehiclesdrive with small inter-vehicular distances. The many benefitsof autonomous platooning includes improved fuel economy,less congestion and safer transportation. To create a safe andfunctional platoon the operational software needs to be able tohandle various road surfaces without the risk of a crash. READ MORE

  6. 5. Temperature Based Estimation of the Time-Resolved Massflux of ICE Exhaust Gas Flow

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mayur Khedekar; [2021]
    Keywords : ICE exhaust flow condition; Thermocouples; Resistance wire thermometers; Nu correlations; ICE exhaust Mass-fluxstudy; Heat transfer coefficient; Heat balance equation for thermocouple; Constant current anemometry; ICE-avgasflödesförhållande; Termoelement; Motståndstrådstermometrar; Nu-korrelationer; ICE-avgas Massflödesstudie; Värmeöverföringskoefficient; Värmebalansekvation för termoelement; Konstant strömanemometri;

    Abstract : The aim ofthe study was to provideinformation and experience gained with fine wire thermocouples (TCs)or resistance wire thermometers (RWTs) temperature signals to estimate the timeresolved heat transfercoefficient. Constant current method was assumed in the study and medium used in this study was air. READ MORE
