The Salt House Project : Designing for Death (DfD)
We as architects consider ourselves creators. We work under the false assumption that buildings will last forever. However, the fact is that every building eventually dies. This thesis rethinks the question of death. The Salt House Project is a product of this questioning. It tests radically rapid …

Estimation of Defocus Blur in Virtual Environments Comparing Graph Cuts and Convolutional Neural Network
… graph cuts and convolutional neural network (DfD-net) to estimate depth from defocus blur using a natural (Middlebury) and a virtual (Maya) dataset. Graph Cuts showed similar performance for both natural and virtual datasets in terms of NMAE and NRMSE. However, with regard to SSIM, the …

Selection and evaluation of joint types and joining processes for concurrent assembly/disassembly-based design
… concerns resulted in the Design-for-Disassembly (DFD) approach, which stresses ease-of-disassembly and environmental compatibility. However, when applied independently of DFA, DFD underestimates the importance of assembly, and consequently can result in increased assembly time and cost. …

Design function deployment: a concurrent engineering design system
… To this end, Design Function Deployment (DFD) has been developed. DFD enables the capture of customers' requirements, the establishment of design specifications and constraints in a solution neutral form, the generation of conceptual designs (architectures), the development of detailed …

Applying "Design for Disassembly" to connection design in steel structures
Design for Disassembly (DfD), also known as Design for Deconstruction, is an emerging initiative of sustainable construction that favors disassembly over demolition, considering a building's full life cycle during the design phase to maximize the materials that can eventually be salvaged for reuse …

Spacecraft design-for-demise strategy, analysis and impact on low earth orbit space missions
… disposal is referred to as Design-for-Demise (DfD). Re-designing spacecraft parts to demise guarantees adherence to NASA reentry requirements that dictate the risk of human casualty anywhere on Earth due to a reentering debris with KE =/> 15J be less than 1:10,000 (0.0001). NASA sanctioned …

Designing buildings for disassembly : stimulating a change in the designer's role
… Here, the potential of Design for Disassembly (DfD) is explored as a solution for a new type of architecture that allows for both recyclability of material and space. Particular attention is given to the benefits that result from this new way of designing while beginning the process of an …

Modeling and Analysis of Optical Blur for Everyday Photography
… an approach to two-frame Depth from Defocus (DFD) in everyday settings. The main challenge here is that the inter-frame motion needs to be estimated in addition to depth from just two images. We propose conditions to control the camera focus to guarantee near-optimal DFD estimation and a …

Identificación de biomarcadores en el músculo post-mortem asociados a defectos de calidad en la carne de vacuno
… de vacuno, concretamente la carne conocida como DFD (del inglés: Dark, Firm, Dry) caracterizada por presentar un valor de pH elevado a las 24 horas post-mortem (pH24 ≥ 6). Este descenso anómalo del pH afecta a la conversión del músculo en carne, resultando en un producto de mala calidad …

Textile Design for Disassembly: A creative textile design methodology for designing detachable connections for material combinations
… the adaptation of Design for Disassembly (DfD) to Textile Design for Disassembly (TDfD) as a strategy to create textile combinations which can be taken apart into their recyclable components at end of life as well as contribute to the longevity of textile products. DfD originates from …

Point Spread Function Engineering for Scene Recovery
… scenes in images. A typical depth from defocus (DFD) technique computes depth from two or more images that are captured with circular aperture lenses of different focus settings. Circular apertures produce circular defocus PSFs. In this thesis, I show that the use of a circular aperture severely …
