1. 1. Prototyping and Evaluation of a Lightweight Simulator Concept Combining Physical and Digital Assets

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Nicke Carlsson; Carl Månsson; [2023-09-27]
   Nyckelord :Virtual reality; extended reality; mixed reality; tactical training; simulation; combat; medical; treatment; tccc; unreal engine;

   Sammanfattning : Serious injuries often occur in high-risk environments such as warfare, urban combat, and traffic accidents. The medical proficiency of soldiers and first responders in these situations is paramount. LÄS MER

3. 2. Människa-dator interaktion under färd : en mixad studie hur designval påverkar förares interaktionstid

   Kandidat-uppsats,

   Författare :Björn Jalmskog; Johannes Tholsgård; [2022]
   Nyckelord :Infotainment system; User interface; HMI; HCI; Interaction design; nderhållningssystem; Användargränssnitt; HMI; HCI; Interaktionsdesign;

   Sammanfattning : Vi har undersökt hur grafisk formgivning och design kan påverka den interaktionstid som krävs av förare, när de framför en bil utrustad med ett underhållningssystem samtidigt som de ska justera ett antal funktioner. Denna teknik är något som vuxit fram inom fordonsbranschen som en del av den pågående globala digitalisering vi ser. LÄS MER

4. 3. Access Point Selection and Clustering Methods with Minimal Switching for Green Cell-Free Massive MIMO Networks

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Qinglong He; [2022]
   Nyckelord :Cell-free massive MIMO; multi-objective optimization; deep reinforcement learning; AP switch ON OFF; energy efficiency; Cellfri massiv MIMO; multiobjektiv optimering; djup förstärkningsinlärning; AP switch ON OFF; energieffektivitet;

   Sammanfattning : As a novel beyond fifth-generation (5G) concept, cell-free massive MIMO (multiple-input multiple-output) recently has become a promising physical-layer technology where an enormous number of distributed access points (APs), coordinated by a central processing unit (CPU), cooperate to coherently serve a large number of user equipments (UEs) in the same time/frequency resource. However, denser AP deployment in cell-free networks as well as an exponentially growing number of mobile UEs lead to higher power consumption. LÄS MER

5. 4. Towards Vision Zero using Virtual Reality

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Vivek Vivian; [2021]
   Nyckelord :;

   Sammanfattning : The number of individuals killed in road accidents around the world is rising. The problem of road safety is a big societal concern. Drivers have a challenge while overtaking vulnerable road users since it necessitates a well-timed, safe interaction between the vehicle, the road user, and approaching traffic. LÄS MER

7. 5. Analysis and Simulation Study of Stochastic Time-To-Collision as a Severity Measure in Traffic Security

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Per Niklas Benzler Waaler; [2020]
   Nyckelord :time; collision; ttc; stochastic; probability; transform; transformation; traffic; data; under; estimation; post; encroachment; mixture; distribution; simulation; study; encounter; conflict; trajectory; prediction; road; user; safety; severity; surrogate; measure; Mathematics and Statistics;

   Sammanfattning : Traffic accidents are extremely rare, creating the need for surrogate methods for safety analysis that makes efficient use of the information provided by traffic conflicts, which also are limited in availability. The severity measure time-to-collision (TTC) in combination with extreme value theory have so far been one of the primary measures used to infer traffic safety levels, but it relies on unrealistic assumptions that results in severity measures that do not always agree well with observed danger.
