In order to represent and reconstruct sharp features (i.e., corners) by an implicitly defined curve, we add so–called corner detector functions, which are special radial basis functions, to the function defining the initial curve. The parameters controlling them are automatically adjusted by applying an evolution process.
The Erdős-Turán law gives a normal approximation for the order of a randomly chosen permutation of n objects. In this paper, we provide a sharp error estimate for the approximation, showing that, if the mean of the approximating normal distribution is slightly adjusted, the error is of order log−1/2n.

یکی از عوامل مهم و تاثیر گذار در شرکت های سرمایه گذاری، محاسبه و مدیریت ریسک می باشد و از انواع ریسکی که این گونه شرکت ها با آن مواجه هستند، ریسک بازار از جایگاه مهمی برخوردار می باشد. امروزه یکی از روش های متداول و کاربردی که در اندازه گیری ریسک بازار مورد استفاده بسیاری از موسسات مالی و سرمایه گذاری دنیا قرار می گیرد، روش ارزش در معرض خطر می باشد. ارزش در معرض خطر حداکثر زیانی را که برای یک ش...
The incidence and patterns of and factors associated with inappropriate antibiotic use were studied in a tertiary care center in Thailand. The incidence of inappropriate antibiotic use was 25%. Admission to the surgical department (adjusted odds ratio, 2.0; P=.02) and to the obstetrics and gynecology department (adjusted odds ratio, 2.0; P=.03) were associated with inappropriate antibiotic use,...
Natural history studies have identified factors that predict evolution to multiple sclerosis or risk of disability accumulation over time. Although these studies are based on large multicentre cohorts with long follow-ups, they have limitations such as lack of standardized protocols, a retrospective data collection or lack of a systematic magnetic resonance imaging acquisition and analysis prot...
BACKGROUND Vaginal breech delivery is associated with adverse perinatal outcome. The aim of this study was to identify factors associated with adverse perinatal outcome in term breech pregnancies, and to provide clinicians an aid in selecting women for a trial of vaginal labor with the fetus in breech position. METHODS We conducted a retrospective, nationwide, Finnish population-based case-co...
An Adjusted Likelihood Ratio Test for Separability in Unbalanced Multivariate Repeated Measures Data
We propose an adjusted likelihood ratio test of two-factor separability (Kronecker product structure) for unbalanced multivariate repeated measures data. Here we address the particular case where the within subject correlation is believed to decrease exponentially in both dimensions (e.g., temporal and spatial dimensions). However, the test can be easily generalized to factor specific matrices ...
