1. 6. Drivers of global land use change : are increasing demands for food and bioenergy offset by technological change and yield increase?

   Författare :Kerstin Engstrom; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Global land use change; food demands; bioenergy demands; technological change; modelling; scenarios; uncertainty;

   Sammanfattning : Globally, the food and energy demands of the growing global population are rising and require increased agricultural production. Additionally, climate change will have adverse effects on agricultural productivity. LÄS MER

3. 7. Transformational knowledge practices in social-ecological systems

   Författare :Diego Galafassi; Victor Galaz; David Tàbara; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transformations; knowledge coproduction; participatory processes; creativity; art-science; scenarios;

   Sammanfattning : Climate change and poverty alleviation are examples of interconnected challenges propelling changes across environmental, social, cultural and political spheres. Interconnected challenges are characterized by multiple causality, feedback loops, non-linear dynamics. LÄS MER

4. 8. Target Tracking in Complex Scenarios

   Författare :Daniel Svensson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ran- dom finite sets; multiple-model filtering; radar.; state estimation; Target tracking; performance evaluation; sensor models;

   Sammanfattning : This thesis is concerned with three important components in target track- ing, namely multiple-model filtering, data association and sensor resolution modeling. For multiple-model filtering, the preferred method has long been the Interacting Multiple Model (IMM) filter, which relies on the assumption that immediate model shifts have the highest probability.

5. 9. Broadband Wireless OFDM Systems

   Författare :Maxime Flament; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel model; 4th Generation Wireless 4GW ; shadowing; MMIC; WLAN; scenarios; mobile data; OFDM; turbo codes; propagation; license-exempt bands; coding; 60 GHz channel; broadband wireless; interference; Virtual Cellular Network VCN ; front-end;

   Sammanfattning : While the readiness of the telecommunication market and the users' need for broadband mobile data are not currently noticeable, a set of presented megatrends and scenarios suggest that broadband mobile data access will develop quickly in the next ten years. Identification of the potential frequency bands offering cheap and trouble-free wireless infrastructure is therefore an important step towards the definition of new air interfaces. LÄS MER

7. 10. Global Ocean Futures : Governance of marine fisheries in the Anthropocene

   Författare :Andrew Merrie; Henrik Österblom; Victor Galaz; Per Olsson; Edward Allison; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fisheries; futures; global governance; marine ecosystems; scenarios; social-ecological system; Sustainability Science; vetenskap om hållbar utveckling;

   Sammanfattning : This PhD thesis provides an analysis of how an adaptive governance approach can be applied to address existing and emerging challenges in global governance with a focus on marine, wild-capture fisheries. All the papers share a coupled social-ecological framing while providing diverse but complementary perspectives. LÄS MER
