  1. 1. Data-driven Interpolation Methods Applied to Antenna System Responses : Implementation of and Benchmarking

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

    Author : Lucas Åkerstedt; [2023]
    Keywords : Model Order Reduction; Loewner Framework; State-space Representation; Nevanlinna-Pick Interpolation; Vector Fitting; Cauchy interpolation; Antenna System Responses; Benchmarking; MoM; Data-driven; Interpolation; Modelordningsreducering; Loewner Ramverk; Tillståndsrepresentation; NevanlinnaPick Interpolering; Vector Fitting; Cauchy Interpolering; Antennsystemsvar; Prestandajämförelse; MoM; Datadriven; Interpolering;

    Abstract : With the advances in the telecommunications industry, there is a need to solve the in-band full-duplex (IBFD) problem for antenna systems. One premise for solving the IBFD problem is to have strong isolation between transmitter and receiver antennas in an antenna system. READ MORE

  3. 2. Compact Ku-band Microwave Filters Realised using Suspended Integrated Stripline Technology

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

    Author : Henrik Åkerberg; [2023]
    Keywords : Suspended Substrate Stripline; Microwave filter; Low Profile; Quasi-Planar; Bandpass Filter; Hängande-Substrat-Stripline; Mikrovågsfilter; Låg profil; Kvasi-planar; Bandpassfilter;

    Abstract : As the fifth generation of telecommunications is deployed, and the number of devices transmitting in the microwave bands grows, effective filtering technologies are becoming ever more important. When a filter is designed, some performance trade-offs have to be made, and one of them is the trade-off between filter size and electrical performance. READ MORE

  4. 3. State Estimation Using a Parametric Approximation of the Viterbi Algorithm

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Åslund Jakob; [2021]
    Keywords : State estimation; Viterbi algorithm;

    Abstract : In this work, a new method of approximating the Maximum-likelihood estimate has been presented. The method consists of first using the Viterbi algorithm to estimate the log likelihood of the state, and then approximating that log likelihood to keep the computational complexity down. READ MORE

  5. 4. Studying the effectiveness of dynamic analysis for fingerprinting Android malware behavior

    University essay from Linköpings universitet/Databas och informationsteknik

    Author : Viktor Regard; [2019]
    Keywords : Android malware; dynamic analysis; droidbox; cuckoodroid; droidscope; mobsf; malware behavior; correlation; pearson correlation; cosine similarity; euclidean distance; chebyshev distance; mahalanobis distance; similarity analysis; static features; dynamic features; tf-idf; term frequency inverse document frequency; AMD; Android malware dataset; malware dataset; UpDroid; EC2;

    Abstract : Android is the second most targeted operating system for malware authors and to counter the development of Android malware, more knowledge about their behavior is needed. There are mainly two approaches to analyze Android malware, namely static and dynamic analysis. READ MORE

  6. 5. Cross-Platform Modelling for Human Activity Recognition System

    University essay from Umeå universitet/Statistik

    Author : Dan Arvidsson; [2018]
    Keywords : ;

    Abstract : Human activity recognition (HAR) systems have a large set of potential applications in healthcare, e.g. fall detection and tracking physical activities. HAR systems based on wearable sensors have gained the most attraction, due to smartphones having these sensors embedded in them. READ MORE
