2. 1. Distributed Optimization of P2P Media Delivery Overlays

   Author : Amir H. Payberah; Seif Haridi; Alberto Montresor; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; P2P overlay networks; P2P live streaming; Distributed optimization; Electronics; Elektronik; Computer and systems science; Data- och systemvetenskap;

   Abstract : Media streaming over the Internet is becoming increasingly popular. Currently, most media is delivered using global content-delivery networks, providing a scalable and robust client-server model. However, content delivery infrastructures are expensive. READ MORE

4. 2. Securing functional programs with floating-label information-flow control

   Author : Pablo Buiras; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; covert timing channels; LIO; concurrency; type-level programming; floating-label; Haskell; internal timing; dynamic enforcement; DC labels; dynamic policies; lazy evaluation; information-flow control; cache-based attacks; language-based security; hybrid enforcement; flow-sensitivity; functional programming; privileges;

   Abstract : The work presented in this thesis focuses on information-flow control systems for functional programs, particularly on the LIO library in Haskell. The thesis considers threemain aspects in this area: timing covert channels, dynamic policies andenforcement mechanisms that improve precision of the analysis. READ MORE

5. 3. Secure GNSS-based Positioning and Timing : Distance-Decreasing attacks, fault detection and exclusion, and attack detection with the help of opportunistic signals

   Author : Kewei Zhang; Panagiotis Papadimitratos; Erik G. Larsson; Christina Pöpper; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Abstract : With trillions of devices connected in large scale systems in a wired or wireless manner, positioning and synchronization become vital. Global Navigation Satellite System (GNSS) is the first choice to provide global coverage for positioning and synchronization services. READ MORE

6. 4. Functional Programming for Embedded Systems

   Author : Abhiroop Sarkar; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Embedded Systems; Timing; Concurrency; Functional Programming; Virtual Machine; Language Runtime;

   Abstract : Embedded Systems application development has traditionally been carried out in low-level machine-oriented programming languages like C or Assembler that can result in unsafe, error-prone and difficult-to-maintain code. Functional programming with features such as higher-order functions, algebraic data types, polymorphism, strong static typing and automatic memory management appears to be an ideal candidate to address the issues with low-level languages plaguing embedded systems.

7. 5. Timing-Based Localization using Multipath Information

   Author : Andreas Bergström; Fredrik Gustafsson; Gustaf Hendeby; Fredrik Gunnarsson; Erik Leitinger; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The measurements of radio signals are commonly used for localization purposes where the goal is to determine the spatial position of one or multiple objects. In realistic scenarios, any transmitted radio signal will be affected by the environment through reflections, diffraction at edges and corners etc. READ MORE
