In this article, we will estimate efficiency amountof decision-making unit by offering the continuous piecewise polynomialextrapolation and interpolation by CCR model input-oriented on the assumptionthat it is constant returns to scale in different times. And finally, we willestimate efficiency amount of decision-making unit indifferent times byoffering an example.

Multi-Layer Perceptrons (MLPs) have been successfully applied in many pattern classification tasks. However, a drawback of these learning machines is that they cannot handle input vectors that present missing data on its features. A recommended way for dealing with missing values is imputation, i.e., to fill in missing data with plausible values. This paper presents a brief review of handling m...

Most of the existing multimodal prototypes enabling users to combine 2D gestures and speech are task-oriented. They help adult users to solve particular information tasks often in 2D standard Graphical User Interfaces. This paper describes the NICE HCA system which aims at demonstrating multimodal conversation between humans and embodied historical and literary characters. The target users are ...

Abstract Heart patients displays several symptoms and it is hard to point them. Data envelopment analysis (DEA) provides a comparative efficiency degree for each decision-making units (DMUs) with several inputs and outputs. Evaluating of hospitals is one of the major applications in DEA. In this study, a comparison of additive model with standard input oriented and output oriented M...

AbstractThe current study examined the modification devices (MDs) used by non-native speakers (NNSs) learning EFL during dyadic task-based interactions. Three meaning-oriented tasks, namely picture-description, spot-the-difference, and opinion-exchange, were used to elicit data from 24(12 male and 12 female, forming 4 male-male, 4 female-female, and 4 male-female dyads) Iranian EFL learners wit...

this study was inspired by vanpatten and uludag’s (2011) study on the transferability of training via processing instruction to output tasks and mori’s (2002) work on the development of talk-in-interaction during a group task. an interview was devised as the pretest, posttest, and delayed posttest to compare four intervention types for teaching the simple past passive: traditional intervention ...

Tasks and business entities are the major constituents of processes but they not always considered equally important. The activity-centric approach artifact-oriented one have radically different visions. former focuses on control flow, i.e., representation precedence constraints between tasks, considers dataflow an add-on. latter emphasizes states defines transitions in a declarative way that m...
