Improving Resolution of Census Data in Metropolitan Areas using a Dasymetric Approach: Applications for the Baltimore Ecosystem Study

open access: yesCities and the Environment, 2008
A dasymetric map is a type of thematic map where boundaries are altered by the distribution of other phenomena. In dasymetric maps, administrative or enumeration boundaries are redrawn to better represent the distribution of data classes.

Solidarity in the Digital Commons

open access: yes
Wittel and Bachman explore solidarity in the field of the digital commons. In particular, they focus on two flagship projects of the digital commons, on the knowledge commons represented by Wikipedia and on the software commons represented by the open-source software movement. The main result of this chapter is surprising.

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

open access: yesAdvanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.
