A Software Product Line (SPL) is a family of similar programs, called variants, generated from common artifact base. Multi SPL (MPL) set interdependent SPLs: each variant can depend on variants other SPLs. MPLs are challenging to model and implement efficiently, especially when different the same must coexist interoperate. We address this challenge by introducing concept variability module (VM)...

Background Standardization of the semen analysis may improve reproducibility. We assessed variability between laboratories in semen analyses and evaluated whether a transformation using Z scores and regression statistics was able to reduce this variability. MaterialsAndMethods We performed a retrospective cohort study. We calculated between-laboratory coefficients of variation (CVB) for sperm c...

Upscaling based on the bandwidth of the kernel function is a flexible approach to upscale the data because the cells will be coarse-based on variability. The intensity of the coarsening of cells in this method can be controlled with bandwidth. In a smooth variability region, a large number of cells will be merged, and vice versa, they will remain fine with severe variability. Bandwidth variatio...

In this paper, we have examined the effect of climate variables on the yield average and variability of major grain crops (rice, maize, and wheat) in Iran from 1983 to 2014. For this purpose, we made use of the Just and Pope Production Function crop yields panel data. The results revealed that the influences of climate variables were different in the crops. The time trend positively influenced ...

By its frequency, colorectal cancer (CRC) has become a serious public health problem. BAT25 marker is included in the panel of five markers dedicated to the diagnosis of CCR microsatellite instability. The objective of this study was to evaluate the polymorphism and genetic diversity of the BAT25 marker in CRC cases in Senegal. This prospective study was performed on 22 CRC patients. After DNA ...

The research examined effect of climate variability on yield of the two dominant cool weather cereals (wheat and barley) in central highland and Arssi grain plough farming systems of Ethiopia using eight round unbalanced panel data (1994-2014). The stochastic frontier model result revealed that production inputs for producing wheat and barley in the two farming system had significant effect. Cr...

Middle and southern Iraq suffers from polluted soils due to crude oil, spilled on land, leakage from transmitting pipe networks, or petroleum products from refineries. Many researchers have studied pollution impacts on the soil in details, but there is a clear lack of investigation on the influence of crude oil on soil erodibility. Recent researches have investigated the influence of pollution ...

Objectives: Knowledge about gender differences in intra-limb coordination during walking provides insight into the adaptability of central nervous system for controlling gait in older adults. We assessed the variability and phase dynamic of the intra-limb coordination in older men and women during walking. Methods: Twenty two older people, 11 female and 11 male, participated in this study. T...
