2. 6. Secure emergency communications of emergency responders : a case study of Kemi municipality in Finland

   Author : Heidi Hartikainen; Erik Borglund; Luleå tekniska universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; emergency management; information security; emergency response; emergency communications; secure communications; Data- och systemvetenskap; Computer and Systems Science;

   Abstract : Emergency response is highly time-critical and information dependent: every moment counts and organizations need to access various information that supports their decision making and informs them about the scale and location of the emergency, the damages, and the availability of human and physical resources. This kind information can originate from many different places and the situation can be stressful as there is a need to communicate quickly, reliably and accurately within their own organization, but also inter-organizationally.

4. 7. Multiantenna Cellular Communications : Channel Estimation, Feedback, and Resource Allocation

   Author : Emil Björnson; Björn Ottersten; Mats Bengtsson; Marios Kountouris; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel estimation; limited feedback; multicell communications; resource allocation;

   Abstract : The use of multiple antennas at base stations and user devices is a key component in the design of cellular communication systems that can meet the capacity demands of tomorrow. The downlink transmission from base stations to users is particularly limiting, both from a theoretical and a practical perspective, since user devices should be simple and power-efficient, and because many applications primarily create downlink traffic (e.

5. 8. FASHIONABLE POLITICS The discursive construction of ethical consumerism in corporate communications, news media, and social media

   Author : Johanna Arnesson; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ethical consumerism; neoliberalism; political brand cultures; consumer culture; critical discourse analysis; media and communication studies;

   Abstract : This thesis investigates the discursive construction of ethical consumerism – a notion that encompasses both ‘conscious’ consumption choices and responsible’ corporate activities – in mediated discourses about fashion and clothing consumption in Sweden. Drawing on the discourse-historical approach within critical discourse analysis, the study provides an empirical examination of discursive elements in corporate communications, newspapers, and social media, which construct the market as the best solution to social injustice and climate change.

6. 9. Mobile Satellite Broadcast and Multichannel Communications : analysis and design

   Author : Cristoff Martin; Björn Ottersten; Jack Winters; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; communications; satellite broadcast; mobile; MIMO; asymptotic analysis; spatial multiplexing; Signalbehandling; Signal processing; Signalbehandling;

   Abstract : In this thesis, analytical analysis and design techniques for wireless communications with diversity are studied. The impact of impairments such as correlated fading is analyzed using statistical models. Countermeasures designed to overcome, or even exploit, such effects are proposed and examined. READ MORE
