A Bayesian framework to predict deformations during supported excavations based on a semi-empirical method

The ground movements induced by the construction of supported excavation systems are generally predicted in the design stage by empirical/semi-empirical methods. However, these methods cannot account for the site-specific conditions and for information that become available as an excavation proceeds. A Bayesian updating methodology is proposed to update the predictions of ground movements in the later stages of excavation based on recorded deformation measurements. As an application, the proposed framework is used to predict the three-dimensional deformation shapes at four incremental excavation stages of an actual supported excavation project.

The limits of inclusive design in the current design practice

The adoption of inclusive design principles and methods in the design practice is meant to support the equity of use of everyday products by as many people as possible independently of their age, physical, sensorial and cognitive capabilities. Although the intention is highly valuable, inclusive design approaches have not been widely applied in industrial context. This paper analyses the findings of an empirical research conducted with industrial designers and product managers. The research indicates some of the hindrances to the adoption of inclusive design, such as the current way the market is considered and targeted, and; the way the designers are driven by the project's brief and budget to orient their research strategy and activities. The paper proposes a way to improve the current industrial mode by strategically supplying clients, designers or both together with information about inclusivity. © 2013 Taylor & Francis Group.
