应用于学生管理中的一种数学方法     

宋虎森 《长治学院学报》2014,(5)

重点管理法是将学生需要管理的事项,按其代表性、独特性等区分,并辅助一些简便的数学计算。以花费的时间或费用多寡排序,对学生加以分类,由此对重点类学生进行严格管控,次重点类学生进行一般管控,普通类学生进行简单管控即可。  相似文献   

微课勿重走“课内整合”老路——对微课应用的再思考     

王竹立 《电大教学》2014,(5):34-40

当前,微课研究正在陷入两个误区：一方面对微课的定义陷入繁琐论证之中,二是试图用微课改变学校内的课堂教学模式。微课是为在线学习而生的,是一种在线学习资源,应对现有的网络视频资源进行“微课化”改造。教育变革可能不是通过改造课堂而实现的,而必须通过发展网络教育与在线学习才能取得突破。  相似文献

Compression of double array structures for fixed length keywords     

Masao Fuketa  Hiroya Kitagawa  Takuki Ogawa  Kazuhiro Morita  Jun-ichi Aoe 《Information processing & management》2014

A trie is one of the data structures for keyword matching. It is used in natural language processing, IP address routing, and so on. It is represented by the matrix form, the link form, the double array, and LOUDS. The double array representation combines retrieval speed of the matrix form with compactness of the list form. LOUDS is a succinct data structure using bit-string. Retrieval speed of LOUDS is not faster than that of the double array, but its space usage is smaller. This paper proposes a compressed version of the double array by dividing the trie into multiple levels and removing the BASE array from the double array. Moreover, a retrieval algorithm and a construction algorithm are proposed. According to the presented experimental results for pseudo and real data sets, the retrieval speed of the presented method is almost the same as the double array, and its space usage is compressed to 66% comparing with LOUDS for a large set of keywords with fixed length.  相似文献   

Determination of Acid β-Galactosidase Activity: Methodology and Perspectives     

Radoslaw Kwapiszewski  Justyna Szczudlowska  Karina Kwapiszewska  Michal Chudy  Zbigniew Brzozka 《Indian journal of clinical biochemistry : IJCB》2014,29(1):57-62

Early, accurate diagnosis of lysosomal storage disorders is a major challenge, even for trained specialists. Finding innovative, accurate diagnostic methods, and high throughput, cost-effective tools are crucial to medical progress and will contribute to improved quality of life. The goal of this work was to improve currently used protocols to determine activity of acid β-galactosidase, and discuss the possibility analysing lysosomal enzymes with microfluidic systems. A principle of the determination of β-galactosidase activity was fluorometric measurement of a deprotonated form of 4-methylumbelliferone released in the enzymatic reaction. Measurements were performed using Jurkat T cells as a source of the enzyme. We observed the temperature-dependent substrate inhibition effect and determined the substrate (4-MU-β-d-galactopyranoside) concentration which should be used to determine acid β-galactosidase activity at 37 °C (0.8 mM) and at room temperature (0.6 mM). We proved that the sample incubation time may be significantly reduced to only a few minutes. We also showed that the amount of alkaline buffer used to stop the enzymatic reaction may be minimized and even, in some cases, eliminated. The presented results show how the sensitivity of the available methods to diagnose patients suffer from gangliosidosis GM1 or Morquio B disease can be improved. The proposed method may be easily implemented with microfluidic systems, which currently are promising tools for point-of-care applications.  相似文献
