This paper presents a review of conventional and novel carrier-based PWM methods that are used for control of multilevel inverters. Among the discussed methods are Phase disposition (PD) PWM, Opposite Phase disposition (POD) PWM, Alternative Phase disposition (APOD) PWM, Phase Shifted PWM and Asymmetrical PWM. The paper shows the simulation results and comparison of these methods. Key-Words: Re...

CONTEXT Gratitude intervention is expectedly an effective intervention to reduce depression and improve the quality of life in schizophrenic patients, but there is a lack of literature on it. AIMS We attempted to develop and test the effectiveness of the gratitude disposition promotion program for chronic schizophrenic patients in Korea. SETTINGS AND DESIGN Nonequivalent control group pre- ...

Aims While the disposition index provides a useful measure of B-cell function, its calculation requires the performance of a frequently sampled intravenous glucose tolerance test (FSIVGTT). Recently, the demonstration of a hyperbolic relationship between indices of insulin secretion and insulin sensitivity derived from the oral glucose tolerance test (OGTT) has led to the introduction of two no...

the current study examined interrelation of affectivity, emotional intelligence and personality and their roles in sport coaches’ transformational leadership style using their disposition. data are collected from 206 sport coaches. pearson correlation coefficient was used to analyze data. the results showed a positive deep relationship between positive affectivity with personality (r=0.251, p

OBJECTIVES We examined the association between anticholinergic medication exposure and subsequent cognitive and physical function in patients with delirium superimposed on dementia during rehabilitation. We also examined length of stay and discharge disposition by anticholinergic medication exposure. DESIGN In this secondary analysis we used control group data from an ongoing randomized clini...

BACKGROUND A patient's trajectory through the healthcare system affects resource use and outcomes. Data fields in population-based administrative health databases are potentially valuable resources for constructing care trajectories for entire populations, provided they can capture patient transitions between healthcare services. This study describes patient transitions from the emergency depar...

BACKGROUND Frailty is an aggregate expression of susceptibility to poor outcomes, owing to age-, and disease-related deficits that accumulate within multiple domains. Older patients who are frail before surgery are at an increased risk of morbidity and mortality, and use a disproportionately high amount of healthcare resources. While frailty is now a well-established risk factor for adverse pos...

BACKGROUND Transfer to an emergency room and hospitalization of nursing home residents is a growing problem that is poorly defined and reported. OBJECTIVES To assess the clinical effectiveness of a pilot project involving hospitalization of nursing home residents directly to an acute-care geriatric department. METHODS We retrospectively compared the hospitalization in an acute-care geriatri...

The disposition effect is a phenomenon in which investors hold onto losing assets longer than they hold onto gaining assets. In this study, we used functional magnetic resonance imaging (fMRI) to measure the response of valuation regions in the brain during the decision to keep or to sell an asset that followed a random walk in price. The most common explanation for the disposition effect is pr...
