Submersible Designer

In this lesson students will discover how a submersible's design enables humans to explore the deep ocean. As a result of doing this activity, students will understand that the physical features of water can be restrictive to movement. They will also understand the importance of design in underwater vehicles by designing their own submersible and how submersibles such as Alvin and the Autonomous Benthic Explorer (ABE) use energy, buoyancy, and gravity to enable them to move through the water. This hands-on activity uses online data resources and includes: focus questions, learning objectives, teaching time, audio/visual materials needed, background information, learning procedures, evaluations, extensions, as well as resources and student handouts. Educational levels: High school

Designer/industry interface

The transcript from the discussion panel section of this event provides an interesting exchange of ideas around the notion of textile reuse and value. Following on from the exhibition Ever & Again: Experimental Recycled Textiles in October 2007, the Textiles Environment Design (TED) Project organized a one day Textiles Upcycling Symposium at Chelsea College of Art & Design on Friday 18th July 2008. The aims of the Symposium were to engage the audience and invited fashion and interior textile designers in thinking about high quality and innovative recycling practices for the future (‘upcycling’). The morning session featured the work of 12 of the most well known designers working in this field, including Orsola De Castro – ‘From Somewhere’, Kate Goldsworthy, Amy Twigger Holroyd – ‘Keep and Share’, Emmeline Child – ‘Emmeline4Re’, Kerry Seager - ‘Junky Styling’, Cyndi Rhodes – ‘Worn Again’, and Barley Massey – ‘Fabrications’. For the afternoon session invited key participants from industry contributed to an informal panel discussion with the designers and audience, to discuss the potential for shifting these ideas into mainstream and larger scale commercial production. This was chaired by sustainable textiles expert Dr Jo Heeley. The day also included a keynote speech from Professor Marie O’Mahony and a presentation of the outcomes of the three-year research project led by Rebecca Earley, which has involved teaching staff, researchers and students from Chelsea College of Art & Design

Designer de Sitter Spacetimes

Recent observations in cosmology indicate an accelerating expansion of the universe postulated to arise from some form of dark energy, the paradigm being positive cosmological constant. De Sitter spacetime is the well-known isotropic solution to the Einstein equations with cosmological constant. However, as discussed here, it is not the most general, locally isotropic solution. One can construct an infinite family of such solutions, designer de Sitter spacetimes, which are everywhere locally isometric to a region of de Sitter spacetime. However, the global dynamics of these designer cosmologies is very different than that of de Sitter spacetime itself. The construction and dynamics of these designer de Sitter spacetimes is detailed along with some comments about their implications for the structure of our universe.Comment: 6 pages, no figure, correction of sign in eq.

Designer lipid-like peptides

A crucial bottleneck in membrane protein studies, particularly G-protein coupled receptors, is the notorious difficulty of finding an optimal detergent that can solubilize them and maintain their stability and function. Here we report rapid production of 12 unique mammalian olfactory receptors using short designer lipid-like peptides as detergents. The peptides were able to solubilize and stabilize each receptor. Circular dichroism showed that the purified olfactory receptors had alpha-helical secondary structures. Microscale thermophoresis suggested that the receptors were functional and bound their odorants. Blot intensity measurements indicated that milligram quantities of each olfactory receptor could be produced with at least one peptide detergent. The peptide detergents' capability was comparable to that of the detergent Brij-35. The ability of 10 peptide detergents to functionally solubilize 12 olfactory receptors demonstrates their usefulness as a new class of detergents for olfactory receptors, and possibly other G-protein coupled receptors and membrane proteins

Intelligent design guidance

This paper presents results from an investigation regarding the use of the Design Structure Matrix (DSM) as a means to guide a designer through the calculation of numerical relationships within the early design system Designer. Characteristics, relationships and goals are used within Designer to enable the evaluation and approximation of the design model and are represented within the system as a digraph. Despite being a useful representation of the interactions within the design model, the digraph does not aid the designer in identifying a sequence of activities that need to be performed in order to evaluate the model. The DSM system was used to represent the characteristics and the dependencies obtained through the relationships. The sequence of characteristics within the DSM was optimised and used to produce a design process to guide the designer in model evaluation. The objective of the optimisation was to minimise the amount of iteration within the design process. The process enabled a designer who is unfamiliar with the model to evaluate it and satisfy the design goals and requirements. Both the DSM system and the Designer system are generic in nature andmay be applied to any design problem

Stability in Designer Gravity

We study the stability of designer gravity theories, in which one considers gravity coupled to a tachyonic scalar with anti-de Sitter boundary conditions defined by a smooth function W. We construct Hamiltonian generators of the asymptotic symmetries using the covariant phase space method of Wald et al.and find they differ from the spinor charges except when W=0. The positivity of the spinor charge is used to establish a lower bound on the conserved energy of any solution that satisfies boundary conditions for which $W$ has a global minimum. A large class of designer gravity theories therefore have a stable ground state, which the AdS/CFT correspondence indicates should be the lowest energy soliton. We make progress towards proving this, by showing that minimum energy solutions are static. The generalization of our results to designer gravity theories in higher dimensions involving several tachyonic scalars is discussed.Comment: 29 page
