The Development of Mathematical Models for Preliminary Prediction of Highway Construction Duration
… an understanding of the project factors having a statistically significant relationship with highway construction duration. Other industry sectors have successfully used statistical regression analysis to identify and model the project parameters related to construction duration. While the need is …

Ultimate Compression After Impact Load Prediction in Graphite/Epoxy Coupons Using Neural Network and Multivariate Statistical Analyses
… map (SOM) neural network and multivariate statistical regression analysis (MSRA). An optimized use of these data treatment tools allowed the generation of a simple, physically understandable equation that predicts the ultimate failure load of an impacted damaged coupon based uniquely on the …

Numerical analysis of direct-chill casting of aluminum ingot
… a fully coupled heat-transfer and thermal-stress analysis model, which has been developed using a commercial finite element (FE) package ABAQUS(TM) with a user subroutine developed in-house, the temperature and stress fields were obtained for various casting conditions. Three post-processing …

Speaker model adaptation in automatic speech recognition.
… transform. The third method is based on statistical regression analysis. Apart from transform adaptation, two more adaptation techniques which are based on statistical estimation are also described in detail. The first technique is based on Bayesian inference estimation. The second …

Firm level factors that affect returns to real estate investment trusts
… 1999 and are used as the dependent variable in a statistical regression analysis. The analysis includes independent variables drawn from a database and includes variables to adjust results for the impact of macroeconomic factors. In addition, indexes for the broader markets are identified and …

The acute and long lasting psychological effects of 3, 4-methylenedioxymethampethamine (MDMA, 'ecstasy'): a cohort study conducted during the period 2002-2007
… time; and number of errors. Interestingly, statistical regression analysis predicted that these deficits in executive functioning may be due to MDMA, (1) directly affecting other psychological processes: memory, impulsivity, and sleep, which indirectly affects performance on executive …

Institutional forces and the written business plan: the case of technology entrepreneurs in South Africa
… from a tertiary-level business education. Statistical regression analysis suggested that a range of wider factors appears to be influencing the South African technology entrepreneur's decision to write a business plan. This findings of this research offer practical implications for …

A Model for the PTX Properties of H2O-NaCl
… must be calculated from an equation of state. A statistical model that relates the vapor pressure of H₂O-NaCl to the fluid temperature and composition has been developed. The model consists of equations that predict the vapor pressure of H₂O-NaCl from the eutectic temperature (-21.2°C) to 1500°C …

Counter-flow Ion Mobility Analysis: Design, Instrumentation, and Characterization
… technique is called "counter-flow ion mobility analysis" (CIMA). Theoretical modeling of this new technique predicted that a resolution of over 1000 is possible, which is over one order of magnitude better than that of conventional IMS techniques currently used. A wind tunnel was designed and …

Asymmetric radiant fields and human thermal comfort
… advanced, voxelbased ray techniques and statistical regression analysis were used to accurately model human local geometry-related characteristics, i.e. projected area factors with respect to both direct and diffuse solar radiation, and view factors for individual parts of the human body. …
