  1. 1. Between Modern Schooling and Cultural Heritage : Education and Ethnicity in Southwest China

    Författare :Wei Wang; Pedagogik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Modern schooling; Cultural heritage; Ethnic minority education; Teacher; Teacher education; Teacher educator; Multicultural education; Internal Orientalism; Xishuangbanna 西双版纳 ; Qianjiang 黔江 ; Dai 傣族 ; Tujia 土家族 ; China;

    Sammanfattning : Since the late 1970s, China has experienced remarkable socioeconomic development. The trend towards marketisation and modernisation overturned culturally-rooted lifestyles, and more and more ethnic minorities in China have started to regard their traditional cultures as irrelevant to their livelihoods and future and chosen to move away from them.

  2. 2. Spatially Adaptive Analysis and Segmentation of Polarimetric SAR Data

    Författare :Wei Wang; Yifang Ban; Jianwei Wan; Xiaoxiang Zhu; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polarimetric SAR; Spatially adaptive; Edge detection; Spherically invariant random vector SIRV ; Superpixel; Simple linear iterative clustering SLIC ; Entropy rate; Segmentation;

    Sammanfattning : In recent years, Polarimetric Synthetic Aperture Radar (PolSAR) has been one of the most important instruments for earth observation, and is increasingly used in various remote sensing applications. Statistical modelling and scattering analysis are two main ways for PolSAR data interpretation, and have been intensively investigated in the past two decades. LÄS MER

  3. 3. Muliple-access techniques for adaptive wireless systems

    Författare :Wei Wang; Chalmers University of Technology; []

    Sammanfattning : With the growing demand for mobile content, the roles of mobile handsets have started shifting from merely communication tools to multi-media channels. This trend will push the current 3G/UMTS networks towards higher throughput, mobility and connectivity. LÄS MER

  4. 4. Mathematics textbooks for teaching : An analysis of content knowledge and pedagogical content knowledge concerning algebra in Swedish upper secondary education

    Författare :Wang Wei Sönnerhed; Berner Lindström; Jonas Emanuelsson; Ingemar Holgersson; Göteborgs universitet kommunikation och lärande Institutionen för pedagogik; []
    Nyckelord :mathematics textbooks; school algebra; solving methods; factorization; solving quadratic equations; mathematics teaching; content knowledge; pedagogical content knowledge; geometrical models; algebra history; embedded teaching trajectories;

    Sammanfattning : In school algebra, using different methods including factorization to solve quadratic equations is one common teaching and learning topic at upper secondary school level. This study is about analyzing the algebra content related to solving quadratic equations and the method of factorization as presented in Swedish mathematics textbooks with subject matter content knowledge (CK) and pedagogical content knowledge (PCK) as analytical tools.

  5. 5. 3D Electron Diffraction : Application and Development towards High-quality Structure Determination

    Författare :Yunchen Wang; Wei Wan; Xiaodong Zou; Junliang Sun; Mauro Gemmi; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; three-dimensional electron diffraction; structure determination; rotation electron diffraction; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Electron crystallography has been proven to be effective for structure determination of nano- and micron-sized crystals. In the past few years, 3D electron diffraction (3DED) techniques were used for the structure solution of various types of complex structures such as zeolites, metal-organic frameworks (MOF) and pharmaceutical compounds.
