Retailers are adopting self-service technologies (SSTs) to improve the quality of service. Self-service technologies indicate any technological application, but the most typical SST is interactive kiosks which refer to computer workstations for public access. Kiosks have widely been used for...

This article provides a national perspective on hospital performance for 30-day risk-standardized mortality rates and risk-standardized readmission rates for patients hospitalized with acute myocardial infarction and heart failure.

In 2009, the Centers for Medicare & Medicaid Services publicly reported hospital-level risk-standardized 30-day mortality and readmission rates after acute myocardial infarction (AMI) and heart failure (HF). The authors calculated 30-day mortality and readmission rates for all Medicare...

Econometricians have recently been interested in estimating and testing the mean reversion parameter (κ) in linear diffusion models. It has been documented that the maximum likelihood estimator (MLE) of κ tends to over estimate the true value. Its asymptotic distribution, on the other...

This paper presents a fast coordinated control scheme of the rotor side converter (RSC), the Direct Current (DC) chopper and the grid side converter (GSC) of doubly fed induction generator (DFIG) wind turbine generators (WTGs) to improve the low voltage ride through (LVRT) and high voltage ride...

This paper presents the day-ahead energy planning of passenger cars with 100% electric vehicle (EV) penetration in the Nordic region by 2050. EVs will play an important role in the future energy systems which can both reduce the greenhouse gas (GHG) emissions from the transport sector and...

This paper develops the approximate nite-sample bias of the ordinary least squares or quasi maximum likelihood estimator of the mean reversion parameter in continuous-time Levy processes. For the special case of Gaussian processes, our results reduce to those of Tang and Chen (2009) (when the...
