The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author

Spectral properties of Andreev reflection from quantum turbulence in 3He-B: What do they tell about turbulent fluctuations?
No full textOne of the experimental techniques developed to measure quantum turbulence at low temperatures in 3He-B utilizes the Andreev reflection of thermal quasiparticle excitations from quantized vortices and vortex structures. We present the results of theoretical, numerical, and experimental study of Andreev scattering from quantum turbulence in 3He-B. We analyze the spectral properties of the Andreev reflection and compare these with the spectral properties of superfluid turbulence, and discuss the physical mechanisms responsible for the scaling of spectral densities. Finally, we discuss the relation between our findings and related observables in ordinary turbulence

High-performance, Cost-effective 3D Stacked Wide-Operand Adders
No full textThrough-Silicon Vias (TSV) based 3D Stacked IC (3D-SIC) technology introduces new design opportunities for wide operand width addition units. Different from state of the art direct folding proposals we introduce two cost-effective 3D Stacked Hybrid Adders with identical tier structure, which potentially makes the manufacturing of hardware wide-operand fast adders a reality. An N-bitadder implemented on a K identical tier stacked IC performs in parallel two N=K-bit additions on each tier according to the anticipated computation principle. Inter-tier carry signals performing the appropriate sum selection are propagated by TSVs. The practical implications of direct folding and of our hybrid carry-select/prefix approaches are evaluated by a thorough case study on 65nm CMOS 3D adder implementations, for operand sizes up to 4096 bits and 16 tiers. Our simulations indicate that in almost all configurations at least one of the two proposed 3D stacked hybrid approaches is faster than the fastest 3D folding approach. When considering an appropriate metric for 3D designs, i.e., the delay-footprint-heterogeneity product, the hybrid adders substantially outperform the folding counterparts by a factor in-between 1:67 and 23:95.Accepted Author ManuscriptComputer Engineerin
Neurodevelopmental outcome of preterm infants with ventricular dilatation with and without associated haemorrhage
No full textThis study investigated whether in preterm children who had ventricular dilatation (VD) on neonatal cranial ultrasound outcome at age 8 years was influenced by the additional presence of germinal matrix haemorrhage--intraventricular haemorrhage (GMH-IVH). Six-hundred and ninety-nine preterm infants (<33 wks' gestation, mean 29.6 wks [SD 2.1]) with either normal cranial ultrasound (n=616; 286 females, 330 males), or with VD with (n=66; 32 females, 34 males) or without (n=17; 4 females, 13 males) GMH-IVH were enrolled in the study. At age 8 years outcome was assessed in 567 (81%) of the 699 children by neurological examination, the Test of Motor Impairment (TOMI), the test of Visuo-Motor Integration (VMI), and the Wechsler Intelligence Scales for Children. Results showed that the proportion of children with disabling impairments was higher in the group with VD and GMH-IVH. Performance on TOMI and VMI (even in those without disabling impairments) was poorer in those with VD and GMH-IVH than in children with normal scans or those with VD only. Children with VD and GMH-IVH had significantly lower performance IQ than children with normal ultrasound, whereas those with VD only were not different from those with normal scans. Results suggest the presence of subtle white matter injury that has not been identified by neonatal cranial ultrasound. Although this study did not investigate biochemical markers of haemorrhage, we hypothesize that non-protein-bound iron is likely to be a contributing factor to white matter damage in preterm infants
