New product development (NPD) projects are typically managed through a series of screens, or gates, where ideas compete for resources. Ideas are carved into projects, and these projects are reviewed, and approved or ...

This paper presents a hybrid model for the integrated development of products based on the decision models Funnel and Stage Gate. This hybrid model was designed in its complete and simplified versions with the main purpose ...

In many situations, System Dynamics modelers have to capture attributes of items that are tracked in an aging chain. The outflow of items from the stocks in these chains usually depends on the attributes that are tracked ...

Protein folding occurs in a very high dimensional phase space with an exponentially large number of states, and according to the energy landscape theory it exhibits a topology resembling a funnel. In this statistical ...

Although the external larval morphology of many species of Microhylidae has been characterized, ontogenetic studies in the family are scarce and partial. In the present study, we describe the development of the oral funnel, ...
