In the analysis more specifically in classification of continuous data stream using machine learning algorithms joint occurrence concept drift and imbalanced issue becomes provocative. Also, imbalance is again challenging when multi-class with minority class that too data-difficulty factors. Incremental ensemble models found promising handling theses issues. But most approaches are for two-clas...

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 ...

We develop a multi-objective model for resource allocation problem in PERT networks with exponentially or Erlang distributed activity durations, where the mean duration of each activity is a non-increasing function and the direct cost of each activity is a non-decreasing function of the amount of resource allocated to it. The decision variables of the model are the allocated resource quantities...

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...

Mobile Ad-hoc Network (MANET) is a network which is capable of autonomous operations and operates without base stations and without centralized administration. Nodes cooperate to provide services. In the mobile ad hoc network every node is router as well as host. They support dynamic topology and have limited energy and computed resources. Ad hoc routing protocols like as Dynamic source routing...

In this paper, we study the following theoretical scheduling problem: the tasks of a given application have to be statically distributed and executed on the heterogeneous servers of a multi-user system on a wide area, heterogeneous network, such as Internet. The application is divided into a set of communicating tasks that may be executed on at least one, and possibly several, servers. The proc...

This study investigates the properties of artiicial recurrent neural networks. Particular attention is paid to the question of how these nets can be applied to the identiication and control of non-linear dynamic processes. Since these kind of processes can only insuuciently be modelled by conventional methods, diierent approaches are required. Neural networks are considered to be useful for thi...
