Exposure levels for parametric arrays in light of guideline ambiguities
No full textRecent revelations about ambiguities in guidelines for very-high frequency sound and ultrasound requiremany everyday devices to be revisited in terms of guideline compliance. One device that has a high ultrasound component but is designed for audio broadcast is a parametric array. Acoustic radiation for commercial parametric arrays was measured at a distance of 3.5 m in an anechoic chamber. The output of the device is compared against three international regulations and guidelines for ultrasound exposure. The authors found that the device was not compliant under the conditions tested in the laborator

Rewriting history : postmodern and postcolonial negotiations in the fiction of J.G. Farrell, Timothy Mo, Kazuo Ishiguro and Salman Rushdie
No full textThis thesis is a study of the rewriting of history in the work of four novelists: J. G. Farrell, Timothy Mo, Kazuo Ishiguro and Salman Rushdie. I argue that their work occupies a particular position that is both within contemporary British fiction, yet at one remove from it.
Their work is situated within the context of critiques of history that are the source of a conflict between postmodernism and postcolonialism. I suggest that each writer engages with postmodemist aesthetics often in an attempt to produce critical histones that bear witness to the voices of those hitherto silenced in conventional historiography. However, these novelists remain anxious as to the potential consequences of mobilising postmodernist models of history, particularly as to the problems this creates concerning historical reference. The thesis aims to
identify the range of related attitudes to postmodernist critiques of history at this particular juncture of contemporary fiction in English.
I approach the specific position of the novelists under study through Homi Bhabha's work on the confluence of the postmodern and the postcolonial, focusing in particular on his suggestion that the postmodem refutation of Western epistemology enables a postcolonial space where a new range of histories emerge. Because each writer works between at least two cultures, and primarily within Britain, they negotiate from within received epistemology in an attempt to locate a space at its boundaries where conventional forms of knowledge no longer have efficacy. However, in contrast to Bhabha, these writers struggle to reach this space and remain sceptical as to the usefulness of postmodernism in making available new forms of
historiography. Ultimately, their work enables a critique of current ways of theorising the relationship between the postmodem and the postcolonial in literary studies
Generating high-performance FPGA accelerator designs for big data analytics with Fletcher and Apache Arrow
No full textAs big data analytics systems are squeezing out the last bits of performance of CPUs and GPUs, the next near-term and widely available alternative industry is considering for higher performance in the data center and cloud is the FPGA accelerator. We discuss several challenges a developer has to face when designing and integrating FPGA accelerators for big data analytics pipelines. On the software side, we observe complex run-time systems, hardware-unfriendly in-memory layouts of data sets, and (de)serialization overhead. On the hardware side, we observe a relative lack of platform-agnostic open-source tooling, a high design effort for data structure-specific interfaces, and a high design effort for infrastructure. The open source Fletcher framework addresses these challenges. It is built on top of Apache Arrow, which provides a common, hardware-friendly in-memory format to allow zero-copy communication of large tabular data, preventing (de)serialization overhead. Fletcher adds FPGA accelerators to the list of over eleven supported software languages. To deal with the hardware challenges, we present Arrow-specific components, providing easy-to-use, high-performance interfaces to accelerated kernels. The components are combined based on a generic architecture that is specialized according to the application through an extensive infrastructure generation framework that is presented in this article. All generated hardware is vendor-agnostic, and software drivers add a platform-agnostic layer, allowing users to create portable implementations.Computer Engineerin
The telomere binding protein TRF2 induces chromatin compaction.
No full textMammalian telomeres are specialized chromatin structures that require the telomere binding protein, TRF2, for maintaining chromosome stability. In addition to its ability to modulate DNA repair activities, TRF2 also has direct effects on DNA structure and topology. Given that mammalian telomeric chromatin includes nucleosomes, we investigated the effect of this protein on chromatin structure. TRF2 bound to reconstituted telomeric nucleosomal fibers through both its basic N-terminus and its C-terminal DNA binding domain. Analytical agarose gel electrophoresis (AAGE) studies showed that TRF2 promoted the folding of nucleosomal arrays into more compact structures by neutralizing negative surface charge. A construct containing the N-terminal and TRFH domains together altered the charge and radius of nucleosomal arrays similarly to full-length TRF2 suggesting that TRF2-driven changes in global chromatin structure were largely due to these regions. However, the most compact chromatin structures were induced by the isolated basic N-terminal region, as judged by both AAGE and atomic force microscopy. Although the N-terminal region condensed nucleosomal array fibers, the TRFH domain, known to alter DNA topology, was required for stimulation of a strand invasion-like reaction with nucleosomal arrays. Optimal strand invasion also required the C-terminal DNA binding domain. Furthermore, the reaction was not stimulated on linear histone-free DNA. Our data suggest that nucleosomal chromatin has the ability to facilitate this activity of TRF2 which is thought to be involved in stabilizing looped telomere structures
