On the structure of generalized threshold arch processes
Statistics & Probability Letters, 2010 The aim of this paper is to develop probabilistic studies, useful for applications, namely in what concerns the implementation and validation of subsequent statistical methods. More precisely, we establish new conditions on the stationarity and ergodicity of the GTARCH model and obtain an unique representation of its conditional volatility in terms of ...

Threshold Estimation for a Spectrally Negative Lévy Process [PDF]
Mathematical Problems in Engineering, 2020 Consider a spectrally negative Lévy process with unknown diffusion coefficient and Lévy measure and suppose that the high frequency trading data is given. We use the techniques of threshold estimation and regularized Laplace inversion to obtain the estimator of survival probability for a spectrally negative Lévy process.

Thresholding algorithm for local and parallel processing
Electrical Engineering in Japan, 2005 AbstractIn this paper, we propose a thresholding algorithm. This algorithm works under a severe constraint: each pixel in a processed image must be derived from only information of its neighboring pixels. This constraint is very important for a low‐cost device such as a mobile camera, because it makes it possible to process each pixel in parallel.

Health Literacy, Self‐Efficacy and Knowledge of Sickle Cell Disease Among Caregivers
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Sickle cell disease (SCD) is a hereditary blood disorder in which abnormal haemoglobin leads to severe anaemia, painful crises and organ failure. Caregivers’ health literacy (HL) – their ability to assess, understand and apply information, and interact with healthcare professionals – is crucial for managing children with SCD, yet ...
