Modelling iteration in engineering design
(16th International Conference on Engineering Design (ICED'07)16th International Conference on Engineering Design (ICED'07), 2007-08-28)
This paper examines design iteration and its modelling in the simulation of New Product Development (NPD) processes. A framework comprising six perspectives of iteration is proposed and it is argued that the importance of ...
Experimental behavior of reinforced concrete beams strengthened with prestressed CFRP shear straps
(American Society of Civil EngineersJournal of Composites for Construction (ASCE), 2007)
One promising means of increasing the capacity of existing shear-deficient beams is to strengthen the structure using external prestressed carbon fiber reinforced polymer (CFRP) straps. In this system, layers of CFRP tape ...
Supporting design planning through process model simulation
(University of CambridgeChurchill CollegeDepartment of Engineering, 2007-02-13)
Modelling and analysis of design processes is non-trivial and predicting the behaviour
of such systems is especially challenging. Nonetheless, the effective planning of design projects is critical for many engineering ...

Nonlinear FE analysis of cracks in tension and shear
(Institute of Civil EngineersMagazine of Concrete Research, 2007-05-01)
Smeared-crack finite element (FE) analyses of reinforced-concrete beams strengthened with prestressed carbonfibre-reinforced polymer (CFRP) shear straps have shown that, at high load levels, the stresses in the straps ...
The acoustics of curved and lined cylindrical ducts with mean flow
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsPembroke College, 2007-10-23)
This thesis considers linear perturbations to the steady flow of a compressible inviscid perfect gas along a cylindrical or annular duct. Particular consideration is given to the model of the duct boundary, and to the ...
The fluid mechanics of floating and sinking
(University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2007-10-02)
This thesis is concerned with the fluid mechanics of floating and sinking. More specifically, the majority of this thesis considers the role played by surface tension in allowing dense objects to float.
We first derive ...
Transcriptional profiling of MnSOD-mediated lifespan extension in Drosophila reveals a species-general network of aging and metabolic genes
(2007-12-09)
Abstract Background Several interventions increase lifespan in model organisms, including reduced insulin/insulin-like growth factor-like signaling (IIS), FOXO transcription factor activation, dietary restriction, and ...
Using expression arrays for copy number detection: an example from E. Coli
(2007-06-14)
Abstract Background The sequencing of many genomes and tiling arrays consisting of millions of DNA segments spanning entire genomes have made high-resolution copy number analysis possible. Microarray-based comparative ...
The topology of terminal quartic 3-folds
(University of Cambridge, 2007-06-20)
Let Y be a quartic hypersurface in P^4 with terminal singularities. The Grothendieck-Lefschetz theorem states that any Cartier divisor on Y is the restriction of
a Cartier divisor on P^4 . However, no such result holds ...
