background: with increasing age, some changes appeared in specifications of vessels which including dimensions and elasticity in their. the changes in parameters such as resistance, inertance and compliance vessels appear and eventually changes in the environmental pulse releases are in circulation. these changes clearly appear in specification of photoplethysmogram particularly in the size and...

Piston plays a vital role in almost all types of vehicles. The present study discusses the behavioral study of a piston manufacturing plant. Manufacturing plants are complex repairable systems and therefore, it is difficult to evaluate the performance of a piston manufacturing plant using stochastic models. The stochastic model is an efficient performance evaluator for repairable systems. In...

Multivariate canonical state space dynamic models are developed by studying the eigenstructure of their transition matrices. Observability is introduced for time-varying model components defining locally observable dynamic models. Single component models that have a simple transition matrix are first discussed and categorized according to their forecast function. Then more complicated models, d...

Little research has been conducted so far on causes for errors in business process models. In this paper we investigate on how mainly domain independent factors such as the size or complexity of models influence errors observed in a wide range of existing business process models. In particular, we provide a set of six metrics presumably related to the comprehensibility of both the process model...
