Many experiments record sequential trajectories where each trajectory consists of oscillations and fluctuations around zero. Such can be viewed as zero-mean functional data. When there are structural breaks (on the sequence trajectories) in higher order moments, it is not always easy to spot these by mere visual inspection. Motivated this challenging problem brain signal analysis, we propose a ...

abstract present study used translog cost function for determining break point of paddy farms. requested data set include inputs’ prices and quantities, and production amounts had been acquired from 500 rice farmers of guilan province at 2009. model used in this study is seemingly unrelated regressions (sur). the results showed that labor and pesticides had the highest and lowest share of produ...

We investigate van Rijsbergen’s -measure, break-even point, and 11-point averaged precision, all of which can be translated into 1-dimensional scalar quantity from the precision and the recall. These investigations can be done by comparing to tetrachoric (four-fold) correlation coefficient and phi (four-fold point) coefficient, which are often used as the index of statistical association in a 2...

The Circular Economy introduced new research challenges to be faced. Linear and circular supply chain comparisons require general methodologies obtain significant scalable results. A two-step methodology is here proposed facilitate the interpretation of results during a Life Cycle Assessment (LCA). Firstly, an LCA analysis has been conducted on four single-use - Polypropylene (PP), Polylactic a...
