This paper describes an end-to-end method for extracting moving targets from a real-time video stream, classifying them into predefined categories according to imagebased properties, and then robustly tracking them. Moving targets are detected using the pixel wise difference between consecutive image frames. A classification metric is applied these targets with a temporal consistency constraint...

Predicting the end-to-end packet delay and understanding the Internet dynamics are of great importance for many realtime and nonreal-time applications over the Internet, especially for the quality of service (QoS) provisioning and congestion control. After some preliminary statistical analysis, this paper presents a novel approach to predict the Internet end-to-end delay using multiple-model (M...

In these days interaction between different network applications are becoming more popular and to improve the speed and datatransfer rate delay difference between the multynetworks should minimize. In this paper we propose a Latency EQualization (LEQ) service, which equalizes the perceived latency for all clients participating in an interactive network application. The few routers used in LEQ c...

This paper proposes a stochastic model of an ATM based transport network layer of a UTRAN (UMTS Terrestrial Radio Access Network) that transmits the user data of different services such us voice, real time (RT) data and non-real time (NRT) data. Based on this stochastic model a numerical method is presented for the approximate analysis of end-to-end delay in UTRAN. A detailed discussion is prov...

Packet switched networks and message multiplexing have been a major upgrade for industrial systems communications. In the avionics domain, this evolution was brought by the introduction of Avionics Full Duplex Switched Ethernet (AFDX). Guaranteed upper bounds of end-to-end delays for messages transmitted over an AFDX network are mandatory for certification reasons. In this article, we present t...

Consider a network in which adjacent nodes exchange messages via multiple communication channels. Multiple channels between adjacent nodes are desirable due to their cost effectiveness and improved fault-tolerance. We consider the problem of providing deterministic quality of service guarantees in this network. We show that any scheduling protocol designed for a single channel can be converted ...

In this paper, we explore the use of end-to-end unicast traac measurements to estimate the delay characteristics of internal network links. Experiments consist of back-to-back packets sent from a sender to pairs of receivers. Building on recent work 11, 5, 4], we develop eecient techniques for estimating the link delay distribution. Moreover, we also provide a method to directly estimate the li...

A systematic method for connection-wise endto-end delay analysis in asynchronous transfer mode (ATM) networks is proposed. This method consists of the followings: (i) per-stream nodal analysis; (ii) output processes characterization; and (iii) moment matching scheme. Following our previous work [1], we employ H-MMPPs/Slotted D/1 to model ATM queues. Each virtual connection (VC) in ATM networks ...

abstract background: the pancreatojejunostomy has notoriously been known to carry a high rate of operative complications, morbidity and mortality, mainly due to anastomotic leak and ensuing septic complications. objective: in order to decrease anastomotic leak and its attendant morbidity and mortality in operations requiring a pancreato-jejunal anastomosis, and also in order to simplify the ope...

This paper proposed and evaluates a QOS routing policy in packets topology and irregular traffic of communications network called K-shortest Widest paths Q-Routing. The technique used for the evaluation signals of reinforcement is Q-learning. Compared to standard Q-Routing, the exploration of paths is limited to K best non loop paths in term of hops number (number of routers in a path) leading ...
