英语作文写作技巧初探

大学生普遍认为英语写作比较难,究其原因,造成学生写作难的主要因素大致有以下几个方面:词汇贫乏、语言障碍和写作技能的生疏等.因此,大学生只要在平时的学习中多实践、多模仿,注意文章的构思、段落设计和文章连贯性等因素,就一定能写出一手好的英语文章.     

Starting and Sustaining an Undergraduate Research Program: The SURIEM Experience at Michigan State University

Abstract

Mentoring undergraduate students in research is both rewarding and challenging. In this paper we present how we established a summer Research Experience for Undergraduates (REU) program in the mathematical sciences at Michigan State University. A goal of our REU is to include students who are at an early stage of their study of mathematics. We share our experiences in recruiting students, designing research projects, and mentoring our participants. We discuss the challenges we faced and the solutions we found while working with a diverse group of undergraduate students from across the nation.

金钱会性质新论

金钱会是太平天国时期活跃于浙江南部的一个秘密社会组织.长期以来,史学界对金钱会的性质颇存歧见.从金钱会的领导骨干、会员成份、入会凭证、结社宗旨等方面来看,金钱会既不是"天地会的流派”,也不完全属于"教门”,更不是"农民的魔教团体”,而是一个为响应太平天国农民起义建立起来的亦教亦会的社会组织.     

Hybrid ants-like search algorithms for P2P media streaming distribution in ad hoc networks

Media streaming delivery in wireless ad hoc networks is challenging due to the stringent resource restrictions,po-tential high loss rate and the decentralized architecture. To support long and high-quality streams,one viable approach is that a media stream is partitioned into segments,and then the segments are replicated in a network and served in a peer-to-peer(P2P) fashion. However,the searching strategy for segments is one key problem with the approach. This paper proposes a hybrid ants-like search algorithm(HASA) for P2P media streaming distribution in ad hoc networks. It takes the advantages of random walks and ants-like algorithms for searching in unstructured P2P networks,such as low transmitting latency,less jitter times,and low unnecessary traffic. We quantify the performance of our scheme in terms of response time,jitter times,and network messages for media streaming distribution. Simulation results showed that it can effectively improve the search efficiency for P2P media streaming distribution in ad hoc networks.
