Water quality samples are typically collected less frequently than flow since water quality sampling is costly. Load Estimator (LOADEST), provided by the United States Geological Survey, is used to predict water quality concentration (or load) on days when flow data are measured so that the water quality data are sufficient for annual pollutant load estimation. However, there is a need to ident...

Background: When actual measurement of stature cannot be done, other surrogate parameters can be used to predict stature. Stature in clinical medicine and in the field of scientific research can be easily estimated using various anthropometric parameters like arm span, knee height, foot length and breadth etc. Arm span has been proven to be one of the most reliable predictors. Thus this study w...

In this dissertation, we discuss two methods developed during my PhD study to simulate electron transfer systems. The first method, the semi-classical approximation, is derived from the stationary phase approximation to the path integral in the spin-coherent representation. The resulting equation of motion is a classical-like ordinary differential equation subject to a two-ended boundary condit...

OBJECTIVE We developed a new method of estimating visceral fat area (VFA) using multifrequency bioelectrical impedance (BI). RESEARCH DESIGN AND METHODS We considered abdominal composition as a parallel circuit model composed of VFA and subcutaneous fat area and calculated the impedance of VFA (IP(VFA)) from this model. The methods were tested against measures of VFA by computed tomography (C...

The objective of this study is to develop a multiple linear regression model that measures the relationship between the church services supply and the attendance to the services in the Uppsala diocese, Church of Sweden. By reviewing previous models and examining the nature of data available, two research questions were introduced, namely, the problem of omitted variables and the problem of spat...

Efron, Hastie, Johnstone and Tibshirani (2004) proposed Least Angle Regression (LAR), a solution path algorithm for the least squares regression. They pointed out that a slight modification of the LAR gives the LASSO (Tibshirani, 1996) solution path. However it is largely unknown how to extend this solution path algorithm to models beyond the least squares regression. In this work, we propose a...

FDM(fused deposition modelling) is a RP(rapid prototyping)technique used to manufacture prototypes on additive manufacturing technology.The material used is ABS(acronitirile butadiene styrene) plastic.The prototypes are made layer by layer addition of semi molten plastic and their joining by diffusion welding.In the present study effect of different parameters on response is studied.RSM(respons...

AIM In order to supply a scientific basis for uniting the normal reference value standard of hemoglobin of Chinese middlescent women. METHODS A research is made about the relationship between the normal reference value of 25,917 examples of hemoglobin of middlescent women and altitude in 268 areas in China, the normal reference values of hemoglobin of middlescent women are determined by the h...
