1. E-handelssidoroch laddningstider
Kandidat-uppsats, Mittuniversitetet/Avdelningen för data- och systemvetenskapSammanfattning : In this study, the purpose is to measure how much the response time affect the effectiveness and usability of the user on e-commerce pages, and to evaluate whether displaying a loading symbol affects the user's opinion positively or negatively. This study is based on three theories, Nielsen's (2010) theory of how response time affect users effectiveness, Galetta et al. LÄS MER
2. Frequency Noise in Widely Tunable Lasers for Coherent Communication
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : The objectives of this thesis are to measure the frequency noise of a widely tunable semiconductor laser, determine the main causes for the frequency uctuations and investigate the requirements for laser frequency noise for mQAM modulation formats by means of simulations. The following theoretical aspects are covered: the derivation of the frequency noise spectrum and the detuned loading effect from the rate equations; the shape and the causes of the frequency noise power spectral density; the derivation of the linewidth spectrum from white and 1/f frequency noise; the functionality of the laser and feedback loop used for the measurements.
