poor adhesion between two successive bituminous layers causes adverse effects on the structural strength of the pavement and develops a numbers of premature failure. to improve the adhesion, it is a general practice to apply a tack coat over an existing or newly constructed bituminous surface before laying another bituminous layer. the main objective of this study is to explore the influence of...

Subjective well-being changes over time. While the causes of these have been investigated extensively, few attempts made to capture through computational modelling. One notable exception is study by Rutledge et al. [Rutledge, R. B., Skandali, N., Dayan, P., & Dolan, J. (2014). A and neural model momentary subjective well-being. Proceedings National Academy Sciences, 111(33), 12252–12257. https:...

We consider a stage life testing model and assume that the information at which levels the failures occurred is not available. In order to find estimates for the lifetime distribution parameters, we propose an EM-algorithm approach which interprets the lack of knowledge about the stages as missing information. Furthermore, we illustrate the implementation difficulties caused by an increasing nu...
