1. 1. On Cyber-Security for In-Vehicle Software

   Författare :Aljoscha Lautenbach; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicular Security; Memory Protection; Automotive Security; Memory Exploitation; In-Vehicle Network; Risk Assessment; CAN authentication; Secure Software Development;

   Sammanfattning : We live in a highly connected world, which brings many opportunities, but which also makes us vulnerable to attacks. Security in regular IT systems, such as desktop and server systems, has decades of active research behind it, whereas security in the automotive domain is still a relatively new topic. LÄS MER

3. 2. Process and representation in multiple-cue judgment

   Författare :Anna-Carin Olsson; Peter Juslin; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Psykologi;

   Sammanfattning : This thesis investigates the cognitive processes and representations underlying human judgment in a multiple-cue judgment task. Several recent models assume that people have several qualitatively distinct and competing levels of knowledge representations (Ashby, Alfonso-Reese, Turken, & Waldron, 1998; Erickson & Kruschke, 1998; Nosofsky, Palmeri, & McKinley, 1994; Sloman, 1996).

4. 3. Quantization, Perception and Speech Coding

   Författare :Fredrik Nordén; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis is about compression of speech signals, a research area known as speech coding. The aim of a speech coder is to provide efficient digital representations of speech signals, required in digital transmission and storage systems. Contemporary speech coding algorithms typically separate the speech signal into sets of parameters. LÄS MER

5. 4. Understanding virtual speakers

   Författare :Jens Nirme; The Educational Technology Group; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Verbal Comprehension; Multimodality; Audiovisual integration; Gesture; Educational Technology;

   Sammanfattning : This thesis addresses how verbal comprehension is affected by seeing the speaker and in particular when the speaker is an animated virtual speaker. Two people visually co-present – one talking and the other listening, trying to comprehend what is said – is a central and critical scenario whether one is interested in human cognition, communication or learning.

7. 5. Deep Learning for Active Fire Detection Using Multi-Source Satellite Image Time Series

   Författare :Yu Zhao; Yifang Ban; Andrea Nascetti; Josephine Sullivan; Cartalis Constantinos; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wildfire; Remote Sensing; Active Fire Detection; GOES-R ABI; Suomi-NPP VIIRS; Image Segmentation; Deep Learning; Gated Recurrent Units GRU ; Transformer.; Vilda Bränder; Fjärranalys; Aktiv Branddetektering; GOES- R ABI; Suomi-NPP VIIRS; Bildsegmentering; Djupinlärning; Gated Recurrent Units GRU ; Transformer; Geoinformatik; Geoinformatics;

   Sammanfattning : In recent years, climate change and human activities have caused increas- ing numbers of wildfires. Earth observation data with various spatial and temporal resolutions have shown great potential in detecting and monitoring wildfires. LÄS MER
