There are several environmental factors such as temperature differential, moisture, oxidation, etc. that affect the extended life of the modified asphalt influencing its desired adhesive properties. Knowledge of the properties of asphalt adhesives can help to provide a more resilient and durable asphalt surface. In this study, a hybrid of Bayesian optimization algorithm and support vector regression approach is recommended to predict the adhesion force of asphalt. The effects of three important variables viz., conditions (fresh, wet and aged), binder types (base, 4% SB, 5% SB, 4% SBS and 5% SBS), and Carbon Nano Tube doses (0.5%, 1.0% and 1.5%) on adhesive force are taken into consideration. Real-life experimental data (405 specimens) are considered for model development. Using atomic force microscopy, the adhesive strength of nanoscales of test specimens is determined according to functional groups on the asphalt. It is found that the model predictions overlap with the experimental data with a high R2 of 90.5% and relative deviation are scattered around zero line. Besides, the mean, median and standard deviations of experimental and the predicted values are very close. In addition, the mean absolute Error, root mean square error and fractional bias values were found to be low, indicating the high performance of the developed model.

This research aims to tap into the largely opaque origins of opportunities in the online context by exploring the role of business model development as a key for the creation and configuration of the mental and social infrastructure necessary for the emergence of online entrepreneurial opportunity. Tracing the sources of online entrepreneurial opportunity reveals that successful online entrepreneurs claim to proactively manage their environment in terms of unfolding actions which result in the enactment and creation of entrepreneurial opportunities. Based on this real life contention and the emerging view of entrepreneurial opportunity, this chapter aims to achieve a deeper understanding on the creation of online opportunities through a quantitative study empirically testing the link between business model development and online entrepreneurial opportunity as creation in order to shed light on how business model generation shapes the way entrepreneurs socially co-create opportunities in the online context.
