Fuzzy time series (FTS) is one of the forecasting methods that has been developed until now. The fuzzy a method uses concept logic, which Song and Chissom first introduced. Markov chain in defuzzification. determination length interval plays an important role forming logic relationship (FLR), this FLR will be used to determine value. One can average-based. However, several studies use partition...

introduction in recent years due to problems associated with intensive agricultural systems, the role of legumes in the sustainability of cropping systems has been accelerated (draper, 2006). currently, one of the challenges of energy intensive agricultural systems is monoculture, which is associated with low biological diversity (carmine, 2007). iran has been considered as the area with low ag...

Abstract Al-Osh and Alzaid (1988) consider a Poisson moving average (PMA) model to describe the relation among integer-valued time series data; this model, however, is constrained by underlying equi-dispersion assumption for count data (i.e., that variance mean equal). This work instead introduces flexible contain over- or under-dispersion via Conway-Maxwell-Poisson (CMP) distribution related d...

BACKGROUND Areal bone mineral density is predictive for fracture risk. Microstructural bone parameters evaluated at the appendicular skeleton by high-resolution peripheral quantitative computed tomography (HR-pQCT) display differences between healthy patients and fracture patients. With the simple geometry of the cortex at the distal tibial diaphysis, a cortical index of the tibia combining mat...
