1. 6. Residential Demand Response in the Context of European Union Energy Policy

   Författare :Pia Stoll; Fredrik Gröndahl; Nils Brandt; Lars Nordström; Will Kling; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Industrial Ecology; Industriell ekologi;

   Sammanfattning : In order to achieve energy security, reduce global warming and promote the vision of a common electricity market, the European Union (EU) is transforming the EU electricity grid from a large set of independent hierarchical national grids into one meshed EU-wide grid. For the first time in the history of the electric power industry, residential consumers are being integrated into the grid as active consumers and micro-generators of electricity. LÄS MER

3. 7. 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

4. 8. Streaming Aggregation using Reconfigurable Hardware

   Författare :Prajith Ramakrishnan Geethakumari; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Streaming; Aggregation; Dataflow; FPGA;

   Sammanfattning : High throughput and low latency streaming aggregation is essential for many applications that analyze massive volumes of data in real-time. In many cases, high speed stream aggregation can be achieved incrementally by computing partial results for multiple windows. LÄS MER

5. 9. Impulse Radio UWB for the Internet-of-Things : A Study on UHF/UWB Hybrid Solution

   Författare :Zhuo Zou; Hannu Tenhunen; Tor Sverre Lande; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra-Wideband; impulse radio; IR-UWB; RFID; asymmetric links; UHF UWB hybrid; wireless sensing; energy detection; low power; radio receiver; positioning; Internet-of-Things;

   Sammanfattning : This dissertation investigates Ultra-Wideband (UWB) techniques for the next generation Radio Frequency Identification (RFID) towards the Internet-of-Things (IoT). In particular, an ultra-high frequency (UHF) wireless-powered UWB radio (UHF/UWB hybrid) with asymmetric links is explored from system architecture to circuit implementation. LÄS MER

7. 10. Complex methods of inquiry: structuring uncertainty

   Författare :PETER BEDNAR; Institutionen för informatik; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; information system; Contextual Analysis; Contextual Dependencies; Systems Approaches; Systems Thinking; Organizational change; Complex adaptive systems; Uncertainty management; Organizational Emergence; Change Management; Organizational Learning; Human Activity Systems;

   Sammanfattning : Organizational problem spaces can be viewed as complex, uncertain and ambiguous. They can also be understood as open problem spaces. As such, any engagement with them, and any effort to intervene in order to pursue desirable change, cannot be assumed to be just a matter of ‘complicatedness’. LÄS MER
