  1. 1. Development of GNSS Type Processing for the Characterization of the Mobile Propagation Channel

    Master-uppsats, KTH/Fastigheter och byggande

    Författare :Adrien Bardou; [2021]
    Nyckelord :LMS Channel; Multi-paths; GNSS; SCHUN; Simulation; LMS-kanal; flerv¨agar; GNSS; SCHUN; Simulering;

    Sammanfattning : Mobile communication systems are undergoing significant development on increasingly wide frequency bands (5G in particular). To support this development, a detailed characterization of the propagation of electromagnetic waves in L, S and C band between a station (satellite, airborne or ground) and a mobile platform is necessary to analyze and model the phenomena that have a decisive impact on the performance, availability and operability of systems.

  3. 2. Control and balancing of a small vehicle with two wheels for autonomous driving

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Saro Batmanian; Pasam Naga; [2019]
    Nyckelord :Inverted pendulum; PID controller; Pole placement method; LQR; Hoverboard; Segways; Prototype; Arduino board; Gyroscope; Accelerometer; BLDC motor controllers; EPOS motor controllers; Embedded systems and control and bluetooth remote.;

    Sammanfattning : Control and balancing of an inverted pendulum has gained a lot of attention over the past few decades due to its unstable properties. This has become a great challenge for control engineers to verify and test the control theory. LÄS MER

  4. 3. Automatiska metoder för igenkänning, klassificering och extrahering av objekt från punktmoln insamlade med mobil laserskanning : En litteraturstudie

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad

    Författare :Carl Ljunggren; Emil Lundgren; [2019]
    Nyckelord :Mobil laserskanning; Automatiska metoder; Databearbetning;

    Sammanfattning : Digitalisering är för tillfället ett stort diskussionsämne och i de flesta delarnaav världen pågår det en övergång från analoga till digitala data. Digitala data ärmer flexibelt och kan innehålla mycket högre detaljnivå än vad som ärpraktiskt möjligt med analoga data. LÄS MER

    Sammanfattning : Due to the advancement in technology and the increase in the amount of data beingtransferred through wireless channels, many developments in the techniques and speedof data transfer have been observed in the past few decades. The current trend incellular technology is transforming from 4G to 5G. LÄS MER

  7. 5. Visualizing future buildings : User-centered design process and evaluation of a sensor-based MAR prototype

    Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Daniel Lindström; [2017]
    Nyckelord :Mobile Augmented Reality; MAR; Sensor-based MAR; User-Centered Design; UCD; Human-Computer Interaction; HCI;

    Sammanfattning : Mobile Augmented Reality (MAR) is an emerging technology that, when done right, can offer the users a rich experience. However, as with most emerging technologies, it is primarily technology-driven, often leaving the user needs aside. In this study a sensor-based MAR prototype was developed and evaluated, following a User-Centered Design process. LÄS MER
