During recent years, for the ever-growing number of users with the exponential growth of high-data-rate traffic demand, quality of experience (QoE) has emerged as an important issue, providing important measures and assessment metrics for users, service providers and operators. Meanwhile, rapid development of information and communications technology(More)
We analyze a number of techniques for pricing American options under a regime switching stochastic process. The techniques analyzed include both explicit and implicit discretiza-tions with the focus being on methods which are unconditionally stable. In the case of implicit methods we also compare a number of iterative procedures for solving the associated(More)
OBJECTIVE To assess the clinical and haemodynamic effects of carvedilol for patients with cirrhosis and portal hypertension. DESIGN A systematic review and meta-analysis. DATA SOURCES We searched PubMed, Cochrane library databases, EMBASE and the Science Citation Index Expanded through December 2015. Only randomised controlled trials (RCTs) were(More)
In the past few years, particle filtering has emerged as a powerful methodology for solving problems in communications. Many such problems can be represented as dynamic state-space models that involve nonlinear functions and non-Gaussian noise. These problems are very difficult to solve with classical methods, and as an alternative approach, particle(More)
Microarray technologies, which can measure tens of thousands of gene expression values simultaneously in a single experiment, have become a common research method for biomedical researchers. Computational tools to analyze microarray data for biological discovery are needed. In this paper, we investigate the feasibility of using formal concept analysis (FCA)(More)
Chronic pain is a common long-term condition that affects a person's physical and emotional functioning. Currently, the integrated biopsychosocial approach is the mainstay treatment for people with chronic pain. Self-reporting (the use of questionnaires) is one of the most common methods to evaluate treatment outcome. The questionnaires can consist of more(More)
