2. 1. Conflicting Times : Multiple Temporalities in Contemporary Chinese Science Fiction

   Author : Erik Mo Welin; Joakim Enwall; Hua Li; Uppsala universitet; []
   Keywords : HUMANIORA; HUMANITIES; Science fiction; Chinese literature; Temporality; Time travel; Alternate history; Apocalypse; Chronopolitics; Sinologi; Sinology;

   Abstract : This dissertation explores the intersection of temporality and politics in contemporary Chinese science fiction. Building on previous research on Chinese science fiction, science fiction studies, as well as narrative theory and historical theory, the investigation focuses on eight key texts written by the writers Han Song, Liu Cixin, and Baoshu.

4. 2. Actomyosin in biocomputation

   Author : Aseem Salhotra; Alf Månsson; Henry Hess; Linnéuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; biocomputation; molecular motors; 3-SAT; surface chemistry; actomyosin; actin; myosin II; heavy meromyosin; myosin XI; engineered myosin; in vitro motility assay; nanofabrication; alternate computing; network based biocomputation; protein-surface interaction; longevity; prolongation; surface recycling; affinity purification; blocking actin; Bioteknik; Biotechnology; Biokemi; Biochemistry;

   Abstract : There exist complex mathematical problems that are important in real world applications such as weather prediction, molecular modelling, network route optimization and more. In general, such problems are solved using supercomputers with higher computing efficiency but this also consumes high energy along with high production and maintenance cost. READ MORE

5. 3. Particulate Formation in Gasoline Direct Injection Engines

   Author : Sreelekha Etikyala; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PM; Volatileorganic compounds; Gasoline Direct Injection; Particulate Number; Alternate fuels;

   Abstract : Gasoline direct injection (GDI) engines are facing a great challenge because of the need to comply with increasingly stringent emission regulations while improving fuel economy. GDI engines are popularly known for their high fuel efficiency (by the standards of gasoline engines) and low emissions, enabling higher compression ratios and thus increased volumetric efficiency.

6. 4. Particulate Formation in GDI Engines

   Author : Sreelekha Etikyala; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PM; Alternate fuels; Gasoline Direct Injection; internal combustion engines; Particulate Number; Load transients;

   Abstract : The need to comply with stringent emission regulations while improving fuel economy and reducing criteria pollutant emissions from transportation presents a major challenge in the design of gasoline Direct Injection (DI) engines because of the adverse effects of ultrafine Particulate Number (PN) emissions on human health and other environmental concerns. With upcoming advances in vehicle electrification, it may be the case that electric vehicles completely replace all current vehicles powered by internal combustion engines ensuring zero emissions.

7. 5. The alternate-phase return-to-zero modulation format in high-speed optical-fibre communications

   Author : Marco Forzati; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed optical transmission; return-to-zero; nonlinear optics; dispersion management; phase modulation; modulation formats; Fibre optics communication; fibres;

   Abstract : Increasing the channel bit rate is an efficient way to upgrade traffic capacity in installed transmission links. At bit rates of the order of 40 Gb/s, on-off keying transmission becomes severely impaired by non-linear effects,particularly Intra-channel Cross-Phase Modulation (IXPM) and Intra-channel Four-Wave Mixing (IFWM), which cause pulses in different bit slots to interact with each-other.
