Modelling some structural indicators in an h-index context: A shifted Zipf and a decreasing exponential model
نویسنده
چکیده
We derive the values of the ratio between the e-area and the h-area and the average number of excess citations to papers in the h-core in a shifted Zipf model and in a decreasing exponential citation model.

متن کاملInventory Model for Deteriorating Items Involving Fuzzy with Shortages and Exponential Demand
This paper considers the fuzzy inventory model for deteriorating items for power demand under fully backlogged conditions. We define various factors which are affecting the inventory cost by using the shortage costs. An intention of this paper is to study the inventory modelling through fuzzy environment. Inventory parameters, such as holding cost, shortage cost, purchasing cost and deteriorati...
متن کاملFunctional-Coefficient Autoregressive Model and its Application for Prediction of the Iranian Heavy Crude Oil Price
Time series and their methods of analysis are important subjects in statistics. Most of time series have a linear behavior and can be modelled by linear ARIMA models. However, some of realized time series have a nonlinear behavior and for modelling them one needs nonlinear models. For this, many good parametric nonlinear models such as bilinear model, exponential autoregressive model, threshold...
