1. 1. The Global Fashion System : On its social-ecological intertwinedness

   Författare :Celinda Palm; Sarah E. Cornell; Tiina Häyhä; Fredrik Moberg; Kate Fletcher; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sustainability; Fashion; Social-ecological system; Transdisciplinarity; Critical realism; Positionality; Hållbarhet; Mode; Social-ekologiska system; Tvärvetenskap; Kritisk realism; Positionalitet; vetenskap om hållbar utveckling; Sustainability Science;

   Sammanfattning : The fashion industry contributes to shaping the state of the planet: impacts of production and consumption of textile fast-fashion are rising, and the growing number of sustainability-oriented actions have not slowed current trends. The industry’s (un)sustainability is mainly researched within two epistemic communities: fashion studies concerned with social sustainability, and circular economy focused on material biophysical and technological aspects of material cycles along the value chain.

3. 2. Secure System Virtualization : End-to-End Verification of Memory Isolation

   Författare :Hamed Nemati; Mads Dam; Gustavo Betarte; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Platform Security; Hypervisor; Formal Verification; Theorem Proving; HOL4; Cache attack; Security Monitor; Information Flow; Computer Science; Datalogi;

   Sammanfattning : Over the last years, security-kernels have played a promising role in reshaping the landscape of platform security on embedded devices. Security-kernels, such as separation kernels, enable constructing high-assurance mixed-criticality execution platforms on a small TCB, which enforces isolation between components. LÄS MER

5. 4. Nutrient cycling in agroecosystems: nitrogen cycling in southern Sweden in the 1850s and two Tanzanian villages in the 1990s

   Författare :Lars-Erik Williams; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nutrient; nutrient model; nutrient cycling; nitrogen fixation; nitrogen budget; mixed system; miombo; manure; livestock; land use; historical system; food production; efficiency; crops; agroecosystem; carrying capacity; phosphorus; Scania; sustainability; Plant ecology; Växtekologi;

   Sammanfattning : This study presents a general model for analysing nutrient cycling in agroecosystems. The focus is on food production intensity, human carrying capacity, sustainability and efficiency. The model can be used on systems including different kinds of land uses, which makes it applicable for studies on different scales. LÄS MER

7. 5. Event-Driven Architectures for Heterogeneous Neuromorphic Computing Systems

   Författare :Mattias Nilsson; Fredrik Sandin; Foteini Liwicki; Jerker Delsing; Chiara Bartolozzi; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neuromorphic computing; Mixed-signal; Low-power; Non-von Neumann; Spatiotemporal pattern recognition; System integration; Cyber-Physical Systems; Cyberfysiska system;

   Sammanfattning : Mixed-signal neuromorphic processors have brain-like organization and device physics optimized for emulation of spiking neural networks (SNNs), and offer an energy-efficient alternative for implementing artificial intelligence in applications where deep learning based on conventional digital computing is unfeasible or unsustainable. However, efficient use of such hardware requires appropriate configuration of its inhomogeneous, analog neurosynaptic circuits, with methods for sparse, spike-timing-based information encoding and processing.
