background: municipal solid waste (msw) is the natural result of human activities. msw generation modeling is of prime im­portance in designing and programming municipal solid waste management system. this study tests the short-term pre­diction of waste generation by artificial neural network (ann) and principal component-regression analysis. methods: two forecasting techniques are presented in...

Arterial Blood pressure (BP) is influenced by numerous factors. Guidelines on measurement of BP contain recommendations on the position of the back by advising that the subject should sit with back supported. The objectives of this work are: i) to determine whether unsupported back during BP measurement in sitting position has significant effect on BP, ii) to determine the relationship between ...

The implementation of corrosion detection in submarine pipelines is difficult, and a combined PCA-MLP prediction model proposed to improve the accuracy pipelines. Firstly, rate multiphase flow pipeline South China Sea simulated by De Waard 95 transient simulation software OLGA compared with actual rate; then, according data OLGA, principal component analysis (PCA) used reduce dimensionality fac...

A series of 21 compounds isolated from Curcuma zedoaria was subjected to cytotoxicity test against MCF7; Ca Ski; PC3 and HT-29 cancer cell lines; and a normal HUVEC cell line. To rationalize the structure-activity relationships of the isolated compounds; a set of electronic; steric and hydrophobic descriptors were calculated using density functional theory (DFT) method. Statistical analyses wer...

Multivariate statistical methods including pattern recognition (Principal Component Analysis--PCA) and modeling (Multiple Linear Regression--MLR, Partial Least Squares--PLS, as well as Principal Component Regression--PCR) methods were carried out to evaluate the state of ambient air in Miskolc (second largest city in Hungary). Samples were taken from near the ground at a place with an extremely...

Evaporation is an essential component of hydrological cycle. Several meteorologicalfactors play role in the amount of pan evaporation. These factors are often related to eachother. In this study, a multiple linear regression (MLR) in conjunction with PrincipalComponent Analysis (PCA) was used for modeling of pan evaporation. After thestandardization of the variables, independent components were...

Objective: To evaluate the predictive role of inflammatory parameters, especially monocyte-to-lymphocyte (MLR) ratio, on diagnosis prostate cancer (PCa). Material and Methods: The data patients undergoing biopsy between July 2015 2019 were retrospectively analyzed. including age, PSA, neutrophil-to-lymphocyte (NLR), platelet-to-lymphocyte (PLR), MLR histopathologies recorded. Patients grouped a...
