Network Flow Pattern Extraction by Clustering Eugine KangEugine Kang
This document discusses a study that uses clustering techniques to analyze network flow data and extract patterns of torrent usage at Korea University. The study transforms network flow data by time blocks. It then uses k-means clustering and principal component analysis to identify optimal cluster numbers and visualize cluster formations. The study finds that 7 clusters best captures distinct torrent usage patterns. It analyzes the stability of the clusters and identifies two clusters that show regular torrent usage during working hours and heavy overall usage. The goal is to help network administrators identify times of heavy bandwidth usage.
The document is a clinical practice guideline for acute kidney injury (AKI) published by Kidney Disease: Improving Global Outcomes (KDIGO) in 2012. It contains recommendations on defining and classifying AKI, evaluating patients at risk, preventing AKI, treating AKI with renal replacement therapy, and managing specific causes of AKI like contrast-induced nephropathy. The guideline includes sections on introduction and methodology, definition of AKI, prevention and general treatment of AKI, contrast-induced AKI, and dialysis interventions. It provides tables summarizing recommendation statements and clinical practice recommendations supported by evidence reviews.
