Today, there is a great need for intrusion detection system to detect the unwanted traffic on a network, as the attack on networks has increased exponentially. Hence intrusion detection system is ideal to keep the information safely from attacks. The IDS (intrusion detection system) can be defined as tools, methods or resources to help identify asses and report unauthorized or unapproved network activity. This paper aims at classifying NSL-KDD dataset using decision tree algorithms to construct a model with respect to their metric data and study the performance of decision tree algorithms. The result is compared on the basis of confusion matrices. From the results the authors inferred that random forest is more accurate and random tree ensures speed when compared with other classifiers.

Every mobile operator of today"s world switches their technology over from 2G (second generation) to 3G (third generation) network. Operators are keen analyzing their CDR (call detail record) obtained over the past usage for predicting the behavior of their customers and their usage. The operators are willing to mine knowledge from real-world dataset which implies the pattern of user mentality on this changing world. To identify the usage of 2G and 3G services the classification models were trained using the data collected from PAKDD 2006 dataset. In order to obtain the prediction accuracy, the classifiers were evaluated using 10 folds cross validation. On comparing the results of the experiment, J48 performed more accurately and random tree consumed less time.

作者： chandrasekaran S. Cumming R.G. Rochtchina E. Mitchell P. P. Mitchell 张磊 Department of Ophthalmology University of Sydney Westmead Hospital Hawkesbury Road Westmead NSW 2145 Australia Dr.

Purpose: To examine incident relationships between elevated intraocular pressure (IOP), open-angle glaucoma (OAG), and use of glaucoma medications with 5- year incident cataract. Design: Population-based cohort study. Participants: The Australian Blue Mountains Eye Study examined 3654 participants 21 mmHg in either eye were classified as having ocular hypertension (OH), as were non-OAG subjects with IOP < 22 mmHg using glaucoma medications. Wisconsin levels 4 to 5 were graded as nuclear cataract, at least 5% lens involvement was graded as cortical cataract, and any PSC defined its presence. Results: The 5- year incidence of nuclear cataract was 23.4% (592/2532), or 23.1% (574/2486) after excluding subjects using glaucoma medication. A marginally significant association was found for elevated IOP or OH at baseline and incident nuclear cataract (odds ratio [OR] 1.93 95% confidence interval (CI), 0.97- 3.89, and OR, 1.83 95% CI, 0.96- 3.48, respectively) in subjects not using glaucoma medications, after multivariate adjustment. Age-and gender-adjusted analyses showed similar but statistically significant associations.

研究了细菌胶原酶作为助剂在鞣制系统中的作用，细菌胶原酶的使用能够使单宁更好地向皮内渗透，提升坯革对单宁的吸收率。对不同浓度细菌胶原酶预处理过的坯革的鞣制动力学进行了研究，得到了鞣制过程中坯革对单宁的等温吸收曲线和不同经验公式（Parabolic公式、Cegarra—Puente公式以及修正后的Cegarra—Puente公式）的拟合曲线。结果表明修正后的Cegarra—Puente公式与实验所得数据拟合程度最好，用该公式计算出的吸收速率常数表明，酶助鞣工艺比对照组有更高的速率常数以及更快的吸收动力学。和对照组相比，不同温度条件下的酶处理均会使单宁的吸收率和吸收速率常数明显提高，而且酶处理后坯革的表面活化能明显降低，由Arrhenius公式得出，酶助鞣工艺与对照组相比坯革表面活化能降低了60％。
