Abstract:

Traffic congestion index reflects the state of traffic flow. The detection and analysis on traffic congestion index can be used to estimate the operation status of roads, to plan and organize road traffic for traffic managers, and to make the reasonable decisions of travelers to travel. The traffic conditions of several evaluation indexes were analyzed. Based on the theory of fuzzy mathematics, some membership functions of the evaluating indexes were designed. Three calculation methods of traffic congestion index were proposed. Their calculation results were compared mutually. The conclusion r

<p>Solar PV may cause power congestion to occur in a transmission line when there is high solar irradiance that causing solar PV to generate more power flow than demanded power flow. Transmission line congestion that can be made worst by adding extra power generating farm such as centralized PV farm of renewable energy which helps to deliver customers with the demand or load required. The power generated coming from solar PV is depending on the weather and can definitely worsen the flow in transmission line due to the power captured. In this case, the high solar irradiance can affect the

Abstract:

Efficient transmission of power is a pressing concern in modern power systems as it could relieve additional investments (e.g., right of way) and may improve stability. Non-uniform loading of transmission lines (which normally occurs due to the inefficient transmission of power) may lead to overloading of a few lines. These lines would then be prone to voltage instability. However, this problem would be aggravated under the network contingency condition. This paper focuses on improving the line loadability of the transmission system by considering the benchmark voltage stability index named ra

Abstract:

Background: Pregnant women with congenital heart disease carry a high risk of complications, especially when cardiac function is suboptimal. Increasing evidence suggests that impaired right ventricular (RV) function has a negative effect on placental function, possibly through venous congestion. We report a case series of hepatic and renal venous flow patterns in pregnant women with right ventricular dysfunction after repaired Tetralogy of Fallot (ToF), relative to those observed in normal pregnancy and preeclampsia. Methods: At 20–24 weeks pregnancy, RV function was measured by echocardiograp

ABSTRACT Introduction Mucormycosis is a rare opportunistic invasive fungal infection. The most commonly reported form of the disease is rhinocerebral mucormycosis. Early diagnosis of the disease and aggressive medical and surgical intervention prevent the high morbidity and mortality associated with mucormycosis. Case report A 54-year-old diabetic and hypertensive male presented with severe frontal headache and retro-orbital pain of 4 days duration with high-grade fever. On examination, the patient was conscious and oriented with a blood pressure of 210/100 mm Hg. The pupils were anisocoric. F

Allopurinol is used to reduce total uric acid levels in the body into oxypurinol which can inhibit xanthine oxidase. Allopurinol inhibits the precursors of uric acid formation, xanthine, and hypoxanthine. However, consumption of the drugs can cause side effects on the liver. The aim of the research was to determine the effect of allopurinol induction on the liver histopathology of male mice (Mus musculus) DDY strain. The method used in this research was an experimental design used post-test only that was divided into 4 groups of 4 mice per group. The control group (P0) was given 0.5% Na-CMC, a

Abstract:

The staggered work hours (SWH) policy is a practical strategy for managing travel demand, aiming to spread out the temporal distribution of travel volume by adjusting the schedules of travelers’ activities. The influence of the SWH policy on the commuting patterns of passengers using bus transit is not yet clear. We addressed this issue in a many-to-one bus line, treating commuters as Q-learning agents learning to minimize regrets by selecting appropriate bus runs. The learning outcomes reveal a SWH-induced equilibrium, where commuters departing from the same station with the same work start t

Highways are one of the important facilities and infrastructure for the achievement of an activity, so a good road pavement design is a must. The existence of highways is very necessary for the need for transportation facilities that can reach remote areas. The increase in traffic volume will result in a decrease in service caused by a decrease in road capacity, in line with the results of the survey/identification conducted, road damage is currently occurring in several areas, especially the Pati-Gabus road section, Pati Regency, which causes considerable losses, especially for road users. ,

Roundabouts are a common traffic infrastructure, which are supposed to facilitate safe and smooth traffic flow. Electric bikes as a common traffic tool in a lot of cities in China play an important role in relieving traffic congestion due to the rapid increase of motor vehicles on roads. However, compared with cyclists, e-bikers are more vulnerable because of their higher speed when colliding with motor vehicles. In this research, the spatial-temporal distribution characteristics of conflicts between motor vehicles and electric bikes (e-bikes) at signalized roundabouts are explored. First, the

In urban locations around the world, traffic congestion is a problem. Congestion has increased as a result of inadequate public transportation, stalled development of the road infrastructure, and increased use of private transportation by the public to meet the demand for travel. In developing nations like India, the issue has become more complex due to heterogeneous traffic on subpar road and control conditions. Travel delays and greater vehicle emissions are a result of traffic congestion. In developed nations, studies have been done to quantify congestion in order to assess the current cond

Patients with advanced cancer discharged from hospital also have a readmission rate as high as 34 percent.

Understanding congestion in space-time domain using performance measures is essential prior to suggesting improvement schemes to reduce congestion. With technological advances like Global Positioning System (GPS), many metropolitan planning organizations give more emphasis on travel time based performance measures to quantify congestion, than on traditional way of using volume-to-capacity (V/C) ratios. In India, often it may not be possible to use personal vehicles as probes for travel time data collection. However, the public transit buses fitted with GPS devices could be used as cheap and ef
