  1. 1. Molecular Dynamics Simulations of Biomimetic Carbohydrate Materials

    Författare :Qiong Zhang; Hans Ågren; Robert J. Woods; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics simulation; carbohydrate; cellulose; xyloglucan; cyclodextrin; Molecular biology; Molekylärbiologi;

    Sammanfattning : The present thesis honors contemporary molecular dynamics simulation methodologies which provide powerful means to predict data, interpret observations and widen our understanding of the dynamics, structures and interactions of carbohydrate systems. With this as starting point my thesis work embarked on several cutting edge problems summarized as follows. LÄS MER

  2. 2. Passive Optical Top-of-Rack Interconnect for Data Center Networks

    Författare :Yuxin Cheng; Jiajia Chen; Lena Wosinska; Matteo Fiorani; Qiong Zhang; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical communications; data center interconnects; MAC protocol; dynamic bandwidth allocation.; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Optical networks offering ultra-high capacity and low energy consumption per bit are considered as a good option to handle the rapidly growing traffic volume inside data center (DCs). However, most of the optical interconnect architectures proposed for DCs so far are mainly focused on the aggregation/core tiers of the data center networks (DCNs), while relying on the conventional top-of-rack (ToR) electronic packet switches (EPS) in the access tier.

  3. 3. The Location and Variability of Southern ocean Fronts

    Författare :Robert M. Graham; Agatha M. de Boer; Jonas Nycander; Qiong Zhang; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The location of fronts has a direct influence on both the physical and biological processes in the Southern Ocean. Moreover, the Subtropical Front (STF) is believed play a key role in the global climate system. LÄS MER

  4. 4. Variability and feedbacks in the middle atmosphere

    Författare :Maartje Kuilman; Bodil Karlsson; Qiong Zhang; Hauke Schmidt; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Middle atmosphere dynamics; noctilucent clouds; solar cycle effects; climate feedbacks; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Sammanfattning : The importance of the middle atmosphere for the weather and climate on Earth is increasingly realized. Variability and feedback processes in the middle atmosphere need to be better understood and form the subject of this thesis. LÄS MER

  5. 5. New insights into past atmospheric circulation dynamics

    Författare :Francesco Muschitiello; Barbara Wohlfarth; Richard Gyllencreutz; Qiong Zhang; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Climate change associated with shifts in atmospheric circulation patterns has a great influence on ecosystems and societies. To predict future climate change it is important to obtain a detailed understanding of how climate behaved in the past, with special focus on the regional-scale and short-term expressions of changes in atmospheric circulation dynamics.
