  2. 1. Molecular Dynamics Simulations of Biomimetic Carbohydrate Materials

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

    Abstract : 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. READ MORE

  4. 2. Understanding West African Monsoon Variability : Insights from Paleoclimate Modelling of Past Warm Climates

    Author : Ellen Berntell; Qiong Zhang; Alessandra Giannini; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; West African Monsoon; Monsoon Variability; Paleoclimate; Climate modelling; naturgeografi; Physical Geography;

    Abstract : The Sahel, a water-vulnerable region in West Africa, relies heavily on rainfed agriculture. The region experienced pronounced droughts during the 20th Century, emphasising the socio-economic importance of understanding the drivers of the rainfall variability. READ MORE

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

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

    Abstract : 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.

  6. 4. The Location and Variability of Southern ocean Fronts

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

    Abstract : 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. READ MORE

  7. 5. Variability and feedbacks in the middle atmosphere

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

    Abstract : 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. READ MORE
