The complexity of a network nowadays and its increasingly amount of traffic data has contributed to the occurrence of problems and anomalies. A traffic characterization, called Digital Signature for Network Segment using Flow Analysis (DSNSF) is important to help Network Management in avoiding these problems. We propose two methods to generate a digital signature capable of describing the traffic behavior. For this purpose, we used the statistical method Principal Component Analysis (PCA) and the clustering algorithm K-Means. The resulting DSNSFs are then submitted to testing with real data to evaluate its precision.
Strangulating obstruction of the small intestine by anomalous mesenteric bands is an uncommon cause of colic in horses.The most commonly reported bands are mesodiverticular bands that are embryological remnants of the vitelline arteries. Despite the congenital nature of the anomaly, a wide age range of horses can be affected. This report describes a case of small intestinal strangulating obstruction caused by an unusual, anomalous congenital band attached to the ileocaecal fold in a yearling colt. Information including case background, history, clinical, laboratory, surgical and pathological findings is described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
