Energy transfer and grain size effects during the Standard Penetration Test (SPT) and Large Penetration Test (LPT)
… the mean grain size. Based on this observation, trend-lines with the same shape as the (CD)SPT trend-line are established for the back-calculated (CD)LPT data. A method for generating the grain size effect trend-line for LPT is then proposed. These trend lines provide a rational approach to …

The Altman corporation failure prediction model : applied among South African medical schemes
… 82% accuracy rate and 17.9% error rate. A linear trend line inserted in the graph shows the accuracy improving from 72% to 91% between the period 2003/2004 to 2011/2012. This outcome is consistent with the conclusion in previous studies (Aziz and Humayon, 2006: 27) that showed the accuracy …

Computational studies of electronic structure of doped graphene
… a 2.99eV wide band gap is obtained. An ascending trend line (band gap as a function of dopant atoms) is also obtained from extensive simulation results. The results of this work, i.e., heteroatoms co-doping band gap control suggests novel nanoelectronics device applications based on graphene.

Analysis and behavior of preexisting landslides
… residual and fully softened failure envelopes, a trend line for an effective normal stress of 50 kPa was developed to better describe the stress dependent nature of the drained residual strength and data for seven additional soils were added to the database. In addition, mathematical equations …

Employment opportunities in the South African hotel industry with special reference to tourism
… accepting that oscillations about the suggested trend line will become greater in the future. In order to predict the growth of domestic tourism, cognisance had to be taken of the demographic development of the various population groups. The distribution of wealth among the various groups was …

Automated Machine Learning for Predicting Trends in Time Series Data
… algorithm, TreNet was proposed for predicting trends in time series data. While TreNet was shown to have superior performance to a number of alternative approaches, the validation method used did not take into account the sequential nature of time series data. It also did not deal with model …

Ecological and Genetic Status of the Purple Pitcher Plant, <i>Sarracenia purpurea</i> L., in Maryland and Virginia
… plant population extinction dates, based on trend line from 130 years of data, are 2015 (Maryland) and 2055 (Virginia). Disturbance, especially natural fire, played an essential role in maintaining purple pitcher plant historically in Maryland and Virginia. <em>Sarracenia purpurea</em> blooms …

On the fretting wear of nuclear power plant heat exchanger tubes using a fracture mechanics approach : theory and verification
… that the prediction of the wear volume using the trend line was close to the prediction of the wear using the experimental one. This discrepancy was adjusted using randomly selected three data points to properly calibrate the crack tip sliding displacement (CTSD). Calibrating the model using three …

Artificial Anisotropy for Transverse Thermoelectric Heat Flux Sensing
… 59°. Data collected are then used to generate a linear trend line that describes the devices response to a given heat flux. These experimental results are compared to theoretical predictions using thermoelectric theory. The results indicate that the device does exhibit transverse thermoelectric …

Rocky Mountain ski resort residential real estate : mile high profits or downhill returns?
… 18 years of data collected, the real price index trended cyclically but steadily upwards, confirming the existence of a robust property market. Using the real price index, a system of equations was developed as the foundation for the econometric model. The New Home Construction Equation (a measure …

Hedging against exporting costs and risks in the South African extractive industry
The revolutionisation of international economies and monetary systems has been taking place since the early 1970s. This occurred due to the diminishing fixed exchange rate systems of, initially, the Gold Standard and subsequently the Bretton Woods System. The collapse of these systems, especially …
