“开心网”是否真开心？

为了写这篇关于开心网的心理学文章，我终于又开始上开心网玩那些小游戏了。实际上，自我停止在自家菜园子种菜和到别人园子里“偷菜”到现在，已经快一年时间了。

Two-Level Genetic Algorithm for Clustered Traveling Salesman Problem with Application in Large-Scale TSPs

Let G = (V, E) be a complete undirected graph with vertex set V, edge set E, and edge weights l(e) satisfying the triangle inequality. The vertex set V is partitioned into clusters V1, V2, …, Vk. The clustered traveling salesman problem (CTSP) seeks to compute the shortest Hamiltonian tour that visits all the verti- ces, in which the vertices of each cluster are visited consecutively. A two-level genetic algorithm (TLGA) was developed for the problem, which favors neither intra-cluster paths nor inter-cluster paths, thus realized inte- grated evolutionary optimization for both levels of the CTSP. Results show that the algorithm is more effec- tive than known algorithms. A large-scale traveling salesman problem (TSP) can be converted into a CTSP by clustering so that it can then be solved by the algorithm. Test results demonstrate that the clustering TLGA for large TSPs is more effective and efficient than the classical genetic algorithm.

Instant Messaging Worms Propagation Simulation and Countermeasures

Instant messaging （IM） has become one of the most popular online communication tools among consumer and enterprise IM users. It provides instant message delivery, as well as convenient file transfer services. The increasing popularity and functionalities of IM programs have made it increasingly attractive for attackers, especially for worm writers. IM contact list offers worm an easy way of finding potential victims so that the worm could achieve a surprising spreading speed. This paper first presents our experimental results of simulating IM worm propagation in the logical network defined by IM contact lists, which is reported to be a scale-free network. Then, the existing proposals for detecting and containing IM worm epidemics are discussed. At last, a new algorithm for this purpose is presented, which is based on the observation of the bi-directional nature of IM worm traffic, and its advantages and possible improvements in implementation are analyzed. The simulation results show the proposed algorithm is of significant effect on restricting IM worm propagation.

Vapor corridor phenomenon and response of vegetation NPP in Longitudinal Range-Gorge Region

To study the causation and ecological effect of ＂Corridor＂ phenomena in the Longitudinal Range-Gorge Region （LRGR） in South China and South-East Asian. Supported by the geographic information system （GIS）, vegetation, climate and topography database of the LRGR are founded, The northernmost limit of the tropical rain forest is 28ο-22, which has been promoted 3 or 4 latitude by Vapor ＂Corridor Phenomenon＂. Through ANN analysis, landform proves to be a very important factor affecting NPP distribution. Affected by longitudinal valley landform and monsoon, moisture and quantity of heat has a longitudinal belt distribution, and NPP distribution has seemly distribution. Take Lyonia ovalifolia, Myrica nana scrub as an example, high NPP valuescrub distributes on a wet-tongue area in the valleys. The minimum temperature sensitive value to NPP is 1.588, and altitude is 1.053, precipitation is 1.006, aspect is 1.003. Corridor phenomenon in the LRGR formed special moisture and heat patterns and brings about a series of ecological effects, such as influencing space distribution of vegetation form and NPP spatial patterns of both vegetations and plants.     

英语编辑过程中要注意的问题分析

本文从期刊编辑中英语编辑过程中要注意的问题来探讨期刊英语中更加要注重翻译信与雅的特点,一般而言英语表达的文体特征可以分为词汇、句法和语篇特征三个部分,那么在编辑过程中,文体特征在很大程度与＂雅＂有密切的联系.期刊翻译原则的产生不是空穴来风,而是英语编辑的内在功能性要求所决定的,从某种意义上讲,英语编辑中要注重＂雅＂和＂信＂的原则.

简论改革开放初始阶段的“双轮驱动”

中国改革开放的初始阶段,党和政府顶层将突破口选择在国营企业,企图通过“放权让利”的方法振兴社会主义经济.但由于引起的严重的体制摩擦等原因,致使未能取得突破而驱动起改革开放之车.却是源自安徽的包产包干到户的农村改革和广东的改革开放先走一步、深圳等经济特区的建立,驱动起整个中国的改革开放.笔者称之为“双轮驱动”.35年的中国改革开放的历史,证明了“双轮驱动”的观点是成立的.
