This paper proposes an agent model with adaptive weight-based multi-objective algorithm to manage road-network congestion problem. Our focus is to construct a quantitative index series to describe the road-network congestion distribution, and use such indexes as weights in the multi-objective algorithm to shunt vehicles on those congested links. First, a multi-agent system is built, where each ...

In wireless sensor network to achieve higher consistency and load balancing the various multipath routing protocols have been proposed. Moreover, wireless sensor network typically incorporates heterogeneous applications within the same network. A sensor node may have multiple sensors i.e. light, temperature, motion etc. with different transmission characteristics. An important function of the t...

This paper presents a framework to carry out an novel method based Optimal Power Flow (OPF) for transmission congestion management in deregulated power system using Thyristor Controlled Series Capacitor (TCSC) and Generation Rescheduling. In the deregulated environment, some generators may not be willing to participate in the congestion management process for their own economic interest or some...

Receiver-driven layered multicast has been designed to support scalable multimedia applications and very recently used to support bulk file transfers. Layered multicast congestion control assumes that all the receivers behind a bottleneck are equally able to subscribe to a particular number of cumulative layers. This paper explores the requirement placed on heterogeneous receivers behind a bott...

Aim of the study: Portal vein congestion index has shown promise in detecting early portal venous hemodynamic changes chronic liver disease. The aim this study was to compare adult patients with disease that healthy controls, and evaluate differences index, if any, between common etiologies (chronic viral hepatitis, alcoholic disease, non-alcoholic fatty disease). Method materials: Eighty parti...

Accidents and congestion are two frustrating events, which can be observed very frequently on roads. Accidents, especially on expressways, can trigger heavy traffic congestions imposing huge external costs and reducing the level of service. Therefore it is obvious that accidents clearly have an impact on congestion. But the opposite, i.e. the effect of congestion on occurrence of accidents, is ...

Whether nasal congestion promotes obstructive sleep apnea is controversial. Therefore, we performed a randomized placebo-controlled cross-over trial on the effects of topical nasal decongestion in patients with obstructive sleep apnea syndrome (OSA) and nasal congestion. Twelve OSA patients with chronic nasal congestion (mean +/- SD age 49.1 +/- 11.1 years, apnea/hypopnea index 32.6 +/- 24.5/h)...

Traffic congestion index (i.e., TCI) is a metric for measuring urban road congestion degree. Since traffic congestion has been one of the major issues in most metropolises, it is a crucial demand to know the TCI of every road segment at every time slot. However, it is a challenging task, because the TCI sensors (e.g., road-side sensors, floating vehicles, etc.) are limited in spatial or tempora...

Many applications of Wireless Sensor Network (WSN) are designed for vital event monitoring and to ensure timeliness and reliability for the measured environmental values. The communication protocol needs to prioritize the real time data and ensure the timely delivery of the data to the sink node. In this paper, a routing protocol for WSN has been proposed with congestion and delay aware mode to...

BACKGROUND Handgrip strength (HGS) is a marker of lean muscle mass. This study aims to test the hypothesis that a low HGS reflects a diseased cardiac status and predicts future risk of circulatory congestion in chronic peritoneal dialysis (PD) patients. METHODS Two hundred and eighteen chronic PD patients were prospectively recruited from a single regional dialysis unit in Hong Kong. HGS, ser...
