چکیده
Traffic measurement provides critical real-world data for service providers and network administrators to perform capacity planning, accounting and billing, anomaly detection, and service provision. In many measurement functions, statistical methods play important roles in system designing, model building, formula deriving, and error analyzing. One of the greatest challenges in designing an online measurement function is to minimize the per-packet processing time in order to keep up with the line speed of the modern routers. To meet this challenge, one should minimize the number of memory accesses per packet and implement the measurement module in the on-die cache memory. Hence, it is critical to make the data structures of a measurement module as compact as possible. This book presents several novel online measurement methods that are compact and fast.

Towards Consumer Ethnocentrism and Animosity in Indonesia
This current study aimed at investigating the effects of gender (male versus female) and age (younger versus older) on consumer ethnocentrism and animosity in Indonesia in regard to eight opposed countries. Based on the ANOVA test, the findings showed that female and young consumers have a higher political and economical animosity; while female and old consumers tend to have higher ethnocent...
متن کاملFUZZY TRAIN ENERGY CONSUMPTION MINIMIZATION MODEL AND ALGORITHM
Train energy saving problem investigates how to control train's velocity such that the quantity of energy consumption is minimized and some system constraints are satis ed. On the assumption that the train's weights on different links are estimated by fuzzy variables when making the train scheduling strategy, we study the fuzzy train energy saving problem. First, we propose a fuzzy energy ...

متن کاملThe Status of Nitric Oxide and its Backup, Heme Oxygenase 1, in Thromboangiitis Obliterans
Background: Until recently, a gene polymorphism in the promoter region of endothelial nitric oxide synthase has been suggested as a risk factor for thromboangiitis obliterans (TAO) development. The aim of this study was to compare the metabolites of nitric oxide (NO) and its backup, heme-oxygenase-1 (HMOX1), between TAO patients and those of a smoking control group matched by race, age, sex, an...
