The MOOC-ability of design education

In the past three years, Massive Open Online Courses (MOOCs) have become an important new way for universities to reach out to possible matriculates, life long learners and alumni. Although MOOCs already cover a vast amount of subjects and curricula, it is remarkable to ascertain the lack of Architectural Design courses on the main platforms...

Informed Design to Robotic Production Systems; Developing Robotic 3D Printing System for Informed Material Deposition

This paper discusses the development of an informed Design-to-Robotic-Production (D2RP) system for additive manufacturing to achieve performative porosity in architecture at various scales. An extended series of experiments on materiality, fabrication and robotics were designed and carried out resulting in the production of a one-to-one scale...

Conforming finite elements with embedded strong discontinuities

The possibility of embedding strong discontinuities into finite elements allowed the simulation of different problems, namely, brickwork masonry fracture, dynamic fracture, failure in finite strain problems and simulation of reinforcement concrete members. However, despite the significant contributions to this field, a general embedded...

Finite element and b-spline methods for one-dimensional non-local elasticity

Non-local elasticity theories have been intensively applied to a wide range of problems in physics and applied mechanics. Most applications are based either on the integrodifferential constitutive Icm proposed by Eringen or on the gradient constitutive law developed by Aifantis and co-workers. In this work, M>e study a one-dimensional non-local...

Inversion of seismic reflection data through focusing

Since most of the easy hydrocarbon reservoirs have been found, accurate sub-surface imaging for oil and gas exploration and production is crucial. Seismic data can provide a band-limited reconstruction of impedance contrasts between different rock formations as well as a subsurface velocity model. Current compute power allows for the use of the...

Higher order implicit time integration schemes to solve incompressible Navier-Stokes on co-located grids using consistent unsteady Rhie-Chow

Noting that time-accurate computations of the unsteady incompressible Navier-Stokes (INS) equations can be computationally expensive, a family of higher order implicit multi-stage time integration schemes (namely ESDIRK) is used for advancing the solution to the unsteady INS in time. The higher order time integration schemes have the potential...

A comparison of explicit continuous and discontinuous Galerkin methods and finite differences for wave propagation in 3D heterogeneous media

On the time-stepping stability of continuous mass-lumped and discontinuous Galerkin finite elements for the 3D acoustic wave equation

We solve the three-dimensional acoustic wave equation, discretized on tetrahedral meshes. Two methods are considered: mass-lumped continuous finite elements and the symmetric interior-penalty discontinuous Galerkin method (SIP-DG). Combining the spatial discretization with the leap-frog time-stepping scheme, which is second-order accurate and...
