Mining Botnets and Their Evolution Patterns

引用

Journal of Computer Science & Technology 2013年第4期28卷 605-615页

作者： Jaehoon Choi Jaewoo Kang Jinseung Lee Chihwan Song Qingsong Jin Sunwon Lee Jinsun uh Department of Computer Science and Engineering Korea University Daou Technology Inc.

The botnet is the network of compromised computers that have fallen under the control of hackers after being infected by malicious programs such as trojan viruses. The compromised machines are mobilized to perform various attacks including mass spamming, distributed denial of service （DDoS） and additional trojans. This is becoming one of the most serious threats to the Internet infrastructure at present. We introduce a method to uncover compromised machines and characterize their behaviors using large email logs. We report various spain campaign variants with different characteristics and introduce a statistical method to combine them. We also report the long-term evolution patterns of the spare campaigns.

DYNAMIC BUILDING SIMULATIONS FOR THE EstABLISHMENT OF A MOROCCAN THERMAL REGULATION FOR BUILDINGS

Journal of Green Building 2014年第1期9卷 145-165页

Comprehensive dynamic building simulations are used in order to conduct sensitivity analyses on the influence of building shell parameters to the heating and cooling demands of a variety of building types in Morocco. In a first step, five climatic zones are defined covering the range of specific heating and cooling demand combinations of a reference building located in eleven locations throughout Morocco. Afterwards, 22 single parameter variations for each building type and each climate zone are performed and analyzed in such a way, that suitable promising combinations can be defined as well. This procedure is faster and easier to analyze than a multidimensional regression. The results show indeed that the selected combinations may reduce energy demands substantially. This paper explains the procedure and results in detail for one residential type of building and for one typical non-residential building. The major overall results are discussed.

哺乳动物性特异性抗原(H-Y抗原)的情况,已取得不少有用的资料;对这种抗原的免疫学、遗传学及生物功能,已有了一定了解。本文对此作一简要综述。H-Y抗原的免疫学在经典的啮齿类动物近交品系的皮肤移植中,证实了雄性特异性移植抗原H-Y(简称为H-Yt)的存在。它具有次要组织相容性抗原的性质。同样,用雌性细胞毒T淋巴细胞(CTL)技术,可检测到H-Y抗原的存在,称之为H-Yc。目前尚无证据表明这两种技术检测到的H-Y抗原是否属于同一种H-Y抗原。雄性特异性抗原还可用血清学技术检测到,称之为H-Ys抗原。
