With the acceleration of the urbanization process, urban waterlogging problems are becoming more and more serious in Nanjing, China. In order to mitigate the urban waterlogging problems, it is necessary to reduce surface runoff from the source by rainwater harvesting and utilization. An urban...

In this paper we focus on numerical analysis of finite element methods with stabilizations for the optimal control of system governed by unsteady Oseen equations. Using continuous equal-order finite elements for both velocities and pressure, two fully discrete schemes are proposed. Convective...

The nitrogen cycle represents one of the most important nutrient cycles found in terrestrial ecosystems. Biological nitrogen removal is widely utilised for elimination of nitrogen from wastewater by means of nitrification and denitrification. Nitrogen removal can also be achieved through...

Purpose – The purpose of this paper is to present a prototype simulation system for driving performance of an electromagnetic unmanned robot applied to automotive test (URAT) to solve that it is difficult and dangerous to online debug control program and to quickly obtain test vehicle dynamic...

Purpose – The paper aims to overcome the shortcomings that proportional‐integral‐derivative (PID) control for unmanned robot applied to automotive test (URAT) needs a priori manual retuning, has large speed fluctuations and is hard to adjust control parameters. A novel control approach...

As the latest government effort to reform China's health care system, Urban Resident Basic Medical Insurance (URBMI) was piloted in seventy-nine cities during the summer of 2007, following State Council Policy Document 2007 No. 20's guidelines. This study presents the first economic analysis of...

The central part of pricing agricultural commodity futures options is to find appropriate stochastic process of the underlying assets. The Black's (1976) futures option pricing model laid the foundation for a new era of futures option valuation theory. The geometric Brownian motion assumption...

Weather conditions are a primary source of dairy production risk. Hot and humid weather induces heat stress, which reduces lactation. Heat abatement, such as ventilation, directly affects the temperature and humidity. Abatement can increase expected profit, but cannot eliminate the lost revenue...

Earlier work (Oster, 2005) has argued, based on existing medical literature and analysis of cross country data and vaccination programs, that parents who are carriers of hepatitis B have a higher offspring sex ratio (more boys) than non-carrier parents. Further, since a number of Asian...

Oster (2005) argued that parents with Hepatitis B (HBV) have more sons, which explained Asia's "missing women". Lin and Luoh (2008) show no relationship between gender and mother's HBV. We test for a relationship between paternal HBV and son share and find none.
