  1. 11. Simulation of Radio Propagation Path in Indoor Environment

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

    Author : Minu Revathikumar; [2022]
    Keywords : Indoor 3D propagation model; millimeter waves mmWaves ; 5G; Basic propagation mechanism; Excess loss; Inomhus 3Dspridnings modell; millimeter vågor mmVågor ; 5G; Grundläggande spridnings mekanism; Överskotts förlust;

    Abstract : Several propagation channel models are designed to verify signal behavior in specific environments for future 5G cellular networks. Hence, with the massive development and demand of indoor wireless systems, a suitable design prior to deployment is required for energy and cost-efficient implementations. READ MORE

  3. 12. RayTracing Analysis and Simulator Design of Unmanned Aerial Vehicle Communication and Detection System in Urban Environment

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

    Author : Jie Huang; [2022]
    Keywords : Drone detection; phased array; angle of arrival; MUltiple SIgnal Classification; raytracing; reflection; diffraction; Drönardetektering; fasad array; ankomstvinkel; MUltiple SIgnal Classification; raytracing; reflektion; diffraktion;

    Abstract : In recent years, unmanned aerial vehicles (UAV), also called drones, have experienced a rapid increase, which leads to the concern of illegal use of them. Passive RF is one of the effective ways to detect drones by receiving drones’ communication signals. READ MORE

  4. 13. Development of Microfluidic 3D Cell Culture with a Nanocellulose-Based Scaffold for Spheroid Formation as a Potential Tool for Drug Screening

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Sara Payande; [2022]
    Keywords : 3D cell culture; Scaffold; Microfluidics; Layer-by-Layer; Cellulose Nanofibrils; Spheroids; HepG2; 3D cellodling; Matris; Mikrofluidik; Layer-by-Layer; Cellulosa Nanofibriller; Sfäroider; HepG2;

    Abstract : Abstract  Lack of clinical relevance is assumed to be the main reason behind the high failure rate of medical drugs in the very initial phases of clinical trials. Clinical relevance is difficult to achieve with current tools as they lack the biological and physiological cues found in vivo. READ MORE

  5. 14. Sann vänskap är ljudet mellan människor

    University essay from Lunds universitet/Företagsekonomiska institutionen
