1. 21. Automated Generation of EfficientBitslice Implementations forArbitrary Sboxes

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

   Author : Augustin Bariant; [2023]
   Keywords : Bitslicing; Cryptography; Whitebox; Compilation; Boolean circuits.; Parallélisation au bit; Cryptographie; Boîte blanche; Compilation; Circuits booléens.; Bitslicing; Kryptografi; Vit låda; Kompilering; Booleska kretsar.;

   Abstract : Whitebox cryptography aims at protecting standard cryptographic algorithmsthat execute in attacker-controlled environments. In these, the attacker is ableto read a secret key directly from memory. Common implementations mask alldata at runtime and operate on masked data by using many small precomputedtables. READ MORE

3. 22. Deep Reinforcement Learning on Social Environment Aware Navigation based on Maps

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

   Author : Victor Sanchez; [2023]
   Keywords : Deep Reinforcement Learning; Environment-aware navigation; Robotics; Artificial Intelligence; Apprentissage par renforcement profond; Navigation consciente de l’humain; Intelligence Artificielle; Robotique; Djup Förstärkande Inlärning; Människomedveten navigering; Robotik; Artificiell Intelligens;

   Abstract : Reinforcement learning (RL) has seen a fast expansion in recent years of its successful application to a range of decision-making and complex control tasks. Moreover, deep learning offers RL the opportunity to enlarge its spectrum of complex fields. READ MORE

4. 23. Towards Navigational Aids using Augmented Reality for People with Alzheimer’s Disease in Outdoor Environments : A user study using HoloLens 2 around a University campus

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

   Author : Léa Prémont; [2023]
   Keywords : Augmented reality; Alzheimer’s disease; Navigation; Assistive technology; HoloLens 2; Optical See-Through; Localization; Kalman filter; Hologram; TLX; SUS; Réalité augmentée; Alzheimer; Navigation; Technologie d’assistance; HoloLens 2; Optical See-Through; Localisation; Filtre de Kalman; Hologramme; TLX; SUS; Förstärkt verklighet; Alzheimers sjukdom; Navigering; Tekniska hjälpmedel; HoloLens 2; Optisk genomskinlighet; Lokalisering; Kalman-filter; Hologram; TLX; SUS;

   Abstract : This paper investigates the potential of augmented reality (AR) as a navigational aid for individuals with Alzheimer’s disease (AD), offering innovative solutions to the evolving challenges of AD care. As the disease progresses, patients often require more assistance and may transition to care centers, resulting in reduced independence. READ MORE

5. 24. Improving Behavior Trees that Use Reinforcement Learning with Control Barrier Functions : Modular, Learned, and Converging Control through Constraining a Learning Agent to Uphold Previously Achieved Sub Goals

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

   Author : Jannik Wagner; [2023]
   Keywords : Behavior Trees; Reinforcement Learning; Control Barrier Functions; Robotics; Artificial Intelligence; Verhaltensbäume; Verstärkendes Lernen; Kontrollbarrierefunktionen; Robotik; Künstliche Intelligenz; Beteendeträd; Förstärkningsinlärning; Kontrollbarriärfunktioner; Robotik; Artificiell Intelligens;

   Abstract : This thesis investigates combining learning action nodes in behavior trees with control barrier functions based on the extended active constraint conditions of the nodes and whether the approach improves the performance, in terms of training time and policy quality, compared to a purely learning-based approach. Behavior trees combine several behaviors, called action nodes, into one behavior by switching between them based on the current state. READ MORE

6. 25. Design of a Dielectric Radome using a Ray-Tracing Model for Satellite Communications

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

   Author : Flores Espinosa Núria; [2023]
   Keywords : Dielectric radome; Ray tracing; Array antenna; Lens antenna; Satellite communications; Radom dielèctric; Traçat de Rajos; Arranjament d’antenes; Antena de lent; Comunicacions per satèl·lit; Dielektrisk radome; Strålspårning; Gruppantenn; Linsantenn; Satellitkommunikation;

   Abstract : In recent years, there has been a huge increase in the use of satellite communications. This has led to a need for more capacity, which can be solved by moving towards higher frequency bands in search of higher bandwidths. READ MORE
