  1. 1. Integration of Attribute-Based Encryption and IoT: An IoT Security Architecture

    Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Ziyad Elbanna; [2023]
    Nyckelord :Internet of things; Attribute based encryption; Fine-grained access control; Key revocation; Proxy re-encryption;

    Sammanfattning : Services relying on internet of things (IoTs) are increasing day by day. IoT makes use of internet services like network connectivity and computing capability to transform everyday objects into smart things that can interact with users, and the environment to achieve a purpose they are designed for.

  3. 2. Detection of performance anomalies through Process Mining

    Master-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :Carmine Marra; [2022]
    Nyckelord :Process mining; Conformance Checking; performance anomalies; ERTMS ETCS; Railway system; complex computer systems.;

    Sammanfattning : Anomaly detection in computer systems operating within complex environments,such as cyber-physical systems (CPS), has become increasingly popularduring these last years due to useful insights this process can provide aboutcomputer systems’ health conditions against known reference nominal states.As performance anomalies lead degraded service delivery, and, eventually,system-wide failures, promptly detecting such anomalies may trigger timelyrecovery responses.

  4. 3. Framework to set up a generic environment for applications

    Master-uppsats, Linköpings universitet/Interaktiva och kognitiva system

    Författare :Ruben Das; [2021]
    Nyckelord :containers; docker; orchestration; kubernetes; infrastructure as code; terraform; mtte;

    Sammanfattning : Infrastructure is a common word used to express the basic equipment and structures that are needed e.g.  for a country or organisation to function properly. The same concept applies in the field of computer science, without infrastructure one would have problems operating software at scale. LÄS MER

  5. 4. A study about differences in performance with parallel and sequential sorting algorithms

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för programvaruteknik

    Författare :Joel Nyholm; [2021]
    Nyckelord :Sorting algorithms; Operating systems; Parallelism; Performance;

    Sammanfattning : Background: Sorting algorithms are an essential part of computer science. With the use of parallelism, these algorithms performance can improve. Objectives: To assess parallel sorting algorithms performance compared with their sequential counterparts and see what contextual factors make a difference in performance. LÄS MER

  7. 5. Dispersion management and characterization of ultrashort laser pulses for the optimization of parametric processes

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Axel Elfving; [2019]
    Nyckelord :frequency resolved optical gating; optical parametric amplification; difference frequency generation; nonlinear optics; laser pulse compression; lasers; optics; Technology and Engineering; Physics and Astronomy;

    Sammanfattning : This thesis set out to continue the development of a short-wave infrared (SWIR) optical parametric amplifier (OPA). The system is based on a Yb-ber chirped pulse amplification (CPA) laser delivering 400 fs long pulses, centered around 1030 nm, at 200 kHz repetition rate and 40 W average power. LÄS MER
