OBJECTIVES Pancreatic enzyme replacement therapy (PERT) remains a backbone in the nutritional treatment of cystic fibrosis. Currently, there is a lack of an evidence-based tool that allows dose adjustment. To date, no studies have found an association between PERT dose and fat absorption. Therefore, the aim of the study was to assess the influence of both the PERT dose and the variability in th...

The Program Evaluation and Review Technique (PERT) has been widely used as a tool for project management. In PERT analysis the activity time distribution is assumed to be a beta distribution, and the mean and variance of the activity time are estimated. The activity mean and variance are very useful to find the expected project duration and variance of the critical path. By generalizing the ass...

Program evaluation and review techniques (PERT) is an efficient tool for large project management. In actual project control decisions, PERT has successfully been applied to business management, industry production, project scheduling control, logistics support, etc. However, classical PERT requires a crisp duration time representation for each activity. This requirement is often difficult for ...

BACKGROUND Integrating newly developed tests and treatments for severe pulmonary embolism (PE) into clinical care requires coordinated multispecialty collaboration. To meet this need, we developed a new paradigm: a multidisciplinary Pulmonary Embolism Response Team (PERT). In this report, we provide the first longitudinal analysis of patients treated by a PERT. METHODS Our PERT includes speci...

In this paper, we describe how a stochastic PERT network can be formulated as a Bayesian network. We approximate such PERT Bayesian network by mixtures of Gaussians hybrid Bayesian networks. Since there exists algorithms for solving mixtures of Gaussians hybrid Bayesian networks exactly, we can use these algorithms to make inferences in PERT Bayesian networks.

Background Pancreatic enzyme replacement therapy (PERT) is widely applied to patients with exocrine pancreatic insufficiency (EPI), but its effect and safety has not been quantified. Therefore we performed a meta-analysis to determine the efficacy and tolerance of PERT on patients with EPI. Materials and Methods PubMed, Medline, Cochrane library database, Evidence-based medicine/clinical tria...

This paper demonstrates the performance of PERT, a new TCP congestion control, for video streaming. PERT stands for Probabilistic Early Response TCP. As a delay based protocol, it measures the delay at the end host and adjusts the congestion window accordingly. As our NS-2 simulation results show, the late packet of the video streams are greatly decreased when applying PERT in heterogeneous env...

OBJECTIVE The benefits of pancreatic enzyme replacement therapy (PERT) in chronic pancreatitis (CP) are inadequately defined. We have undertaken a systematic review and meta-analysis of randomised controlled trials of PERT to determine the efficacy of PERT in exocrine pancreatic insufficiency (EPI) from CP. DESIGN Major databases were searched from 1966 to 2015 inclusive. The primary outcome ...

Difficulties with the interpretation of the parameters of the beta distribution let Malcolm et al. (1959) to suggest in the Program Evaluation and Review Technique (PERT) their by now classical expressions for the mean and variance for activity completion for practical applications. In this note, we shall provide an alternative for the PERT variance expression addressing a concern raised by Hah...
