Liquid helium flows around an oscillating cylinder
No full textThe complementary flows of normal viscous liquid helium (He I) and of superfluid helium (He II) around an oscillating obstacle, of rectangular cross-section, have been studied experimentally by using the particle tracking velocimetry technique, with solid deuterium particles. The observed particle behaviour in He II is very similar to that seen in He I. It seems therefore that, without some kind of special forcing acting differently on each superfluid helium component, on length scales which the experiment can access, the oscillating quantum flow mimics the classical one
Beloved: a political composition
No full textThe emergent term, traumatic fiction describes the extraordinary violence inflicted on individuals and groups during a traumatic twentieth-century history which encompasses two world wars, various genocides, the Great Depression, and the Cold War. Traumatic fiction narratives mirror the neurosis of traumatic experience by distorting conventional narrative structures and using literary techniques like fragmentation, textual gaps, and repetition. They critique the social, economic, and political structures which make and maintain trauma. Traumatic fiction narratives focus on the problems of amnesia and memory in the construction of the historical narrative. It questions a "true" historical narrative by focusing on traditionally suppressed voices. Toni Morrison's novel, Beloved (1987) exemplifies this genre of traumatic fiction. However, critics have confused Toni Morrison's traumatic fiction writing style with music. Critics like Lars Eckstein, Peter J. Capuano, and Joanna Wolfe focus their analysis on Morrison's "jazzthetic" quality or the novel's similarities to a slave song; they also argue that the numerous songs incorporated in the novel make the musical quality of her writing essential to understanding this novel. By focusing on the supposed musical quality of her writing, critics have missed Morrison's political purpose. This paper argues that Beloved shows that the dominant white culture, historically contemptuous of the black experience, defines slavery in ways that create trauma for black Americans. Traumatic fiction, it suggests, allows Morrison to access the past and rewrite slavery's narrative. Traumatic techniques allow Morrison to transform her readers into co-witnesses so that a victim's trauma can be externalized, giving the victims much-needed distance from their trauma. That distance allows victims to revisit, reflect, rework, and retell history from a black perspective in order to transcend shame of slavery imposed by white society. Morrison uses traumatic fiction techniques because they provide a language, unmarked by white discourse, for Morrison to tell a black story of slavery that resists forgetting and silencing. Morrison challenges the seemingly authenticated historical story that upholds individualism in order to create room for a new black cultural memory that highlights community, which is its true story.M.A.Includes bibliographical referencesby Kimberly Rose Rotte
The Driving School System: Learning Basic Driving Skills From a Teacher in a Real Car
No full textTo offer increased security and comfort, advanced driver-assistance systems (ADASs) should consider individual driving styles. Here, we present a system that learns a human's basic driving behavior and demonstrate its use as ADAS by issuing alerts when detecting inconsistent driving behavior. In contrast to much other work in this area, which is based on or obtained from simulation, our system is implemented as a multithreaded parallel central processing unit (CPU)/graphics processing unit (GPU) architecture in a real car and trained with real driving data to generate steering and acceleration control for road following. It also implements a method for detecting independently moving objects (IMOs) for spotting obstacles. Both learning and IMO detection algorithms are data driven and thus improve above the limitations of model-based approaches. The system's ability to imitate the teacher's behavior is analyzed on known and unknown streets, and results suggest its use for steering assistance but limit the use of the acceleration signal to curve negotiation. We propose that this ability to adapt to the driver can lead to better acceptance of ADAS, which is an important sales argument.sponsorship: Sponsored by: IEEE Intelligent Transportation Systems Society

Creation of a framework genetic linkage map of colonial bentgrass and the identification of genomic regions associated with dollar spot resistance.
No full textCreeping bentgrass (Agrostis stolonifera L. 2n=4x=28, A2A2A3A3) is a cool season turfgrass known for its lateral growth habit, fine texture and ability to tolerate low mowing heights. One of the biggest maintenance problems for creeping bentgrass is the fungal disease dollar spot caused by Sclerotinia homoeocarpa. Currently the disease is controlled through heavy fungicide use but a more practical long term approach lies through the development of resistant cultivars. Colonial bentgrass (A. capillaris L. 2n=4x=28, A1A1A2A2) is a species related to creeping bentgrass which is resistant to dollar spot. We have generated fertile creeping x colonial bentgrass interspecific hybrids. One plant, designated TH15, was backcrossed with a different creeping plant to generate a mapping population which segregated for dollar spot resistance. The objective of this thesis was to determine which areas of the colonial bentgrass genome are associated with dollar spot resistance. To do this we used the hybrid backcross population to generate a framework genetic linkage map of colonial bentgrass. We created and annotated EST libraries for both creeping and colonial bentgrass and used these libraries as a resource for mapping genes. A new approach to marker development, termed dideoxy polymorphism scanning, was developed to efficiently map genes on the colonial bentgrass map. The colonial bentgrass linkage map contains 212 AFLPs and 110 gene based markers and totals 1157 cM.
By comparing phenotypic data obtained from field trails we identified regions potentially associated with dollar spot resistance in colonial bentgrass. The segregation of resistance in the backcross population suggests a three gene recessive epistasis model for dollar spot resistance in colonial bentgrass. By comparing genotypes we identified colonial bentgrass loci on groups 2A1 and 3A1 that are common in all resistant individuals. We hypothesize that genes related to dollar spot resistance may lie on these groups. Other resistant backcross individuals not included in the mapping population also shared these loci proportions significantly higher then expected by random chance (p < 0.05). This lends additional support to our model of dollar spot resistance in colonial bentgrass.Ph.D.Includes bibliographical references (p. 144-156)by David Rotte
An examination of some proposed correlates of depressive illness
No full textTen depressed subjects, ten recovered subjects and ten control subjects were assessed by the use of the Beck Depression Inventory, the Hostility Direction of Hostility Questionnaire, the Rotter Internal-External Control Scale and the Bene Anthony Family Relations Test. The depressed subjects differed significantly from the recovered and control group in the amount of hostility shown, and from the control group in the direction of hostility. Depressives did not differ significantly from the other two groups in their scores of the amount of internal control, nor in the way they perceived family relations in childhood. The results were seen to support Freud's and Bibring's theories concerning amount and direction of hostility. Rotter's internal-external control hypothesis could not be demonstrated. Nor did family feelings in childhood contribute to Bibring's theory of helplessness. The Family Relations Test was not able to distinguish between family relations of depressives and non- depressives
Strengthening of thin metallic cylindrical shells using fibre reinforced polymers
No full textSteel silos are widely used as long-term or short-term containers for the storage
of granular solids, of which a huge range are stored, from flour to iron ore pellets,
coals, cement, crushed rocks, plastic pellets, chemical materials, sand, and concrete
aggregates. The radius to thickness ratio for silos is in the range of 200 to 3000, so
they fall into the category of thin shells, for which failure by buckling is the main
concern and requires special attention in design. The primary aim of this thesis is to
investigate the possible application of Fibre Reinforced Polymer (FRP) as a new
repair and strengthening technique to increase the buckling capacity of thin metallic
cylindrical shells. Extensive research has been conducted on the use of fibre
reinforced polymer (FRP) composites to strengthen concrete, masonry and timber
structures as well as metallic beams. However, all these studies were concerned with
failure of the structure by material breakdown, rather than stability. As a result, this
thesis marks a major departure in the potential exploitation of FRP in civil
engineering structures.
Many analyses of cylindrical shells are presented in the thesis. These are all
focussed on strengthening the shell against different failure modes. Two loading
conditions were explored: uniform internal pressure accompanied by axial load near
a base boundary, and axial loads with geometric imperfections. For the latter, local
imperfections are usually critical, and two categories of imperfection were studied in
detail: an inward axisymmetric imperfection and a local dent imperfection.
For the first loading condition, which leads to elephant’s foot buckling, an
analytical method was used to derive general equations governing the linear elastic
behaviour of a cylindrical shell that has been strengthened with FRP subject to
internal pressure and axial compression. It was used to identify optimal application
of the FRP. All the later studies were conducted using nonlinear finite element
analysis (using the ABAQUS program) to obtain extensive predictions of many
conditions causing shell buckling and the strengthening effect of well-placed FRP.
In all the cases studied in this thesis, it was shown that a small quantity of FRP
composite, applied within a small zone, can provide a significant enhancement of the
resistance to buckling failure of a thin metal cylinder. These calculations demonstrate
that this new technique is of considerable practical value. However, it is clear that
not all the relevant questions have been fully answered, so the author poses
appropriate questions and makes suggestions for future work
Modeling Temporally Precise Spike Artefacts to Study Their Impact on Spike Correlation Analyses
No full textDue to technical advances, the number of neurons recorded in parallel increases drastically. This development reveals new types of artefacts: Common noise and cross-talk are observed in the raw parallel recording signals [1-3], as well as hyper-synchronous spike events at sampling rate precision in sorted spike data (‚synchrofacts‘; 3-5). These likely originate from environmental electromagnetic signals that couple into the recording signals. Here we concentrate on synchrofacts and their effects on results of spike data analyses, such as cross-correlation and higher-order synchronous or spatio-temporal spike patterns.In experimental data sets, e.g. recorded in macaque M1/PM1 with 100-electrode Utah arrays and manually spike sorted, we noticed synchrofacts in population histograms at a bin size matching the sampling rate (30 kHz). The complexity distribution [6], i.e. the histogram of synchronous events of a certain size (number of spikes across neurons) and their counts, shows entries up to 60, far larger than predicted by independent data of the same rate. Not all channels participate equally, but this is not related to the spatial electrode distribution.To systematically study the effects of the synchrofacts on analysis results, we formulate a stochastic data generation model in which we have control over synchrofacts, ‚neuronal‘ correlations and firing rates. We model background activity as independent Poisson processes and inject ‚neuronal‘ correlations and synchrofacts each formulated by separate Compound Poisson Processes (CPPs, 7-8). A CPP generates synchronous events with event sizes given by its amplitude distribution and inserts these spikes randomly into the neuronal spike trains. To model the observed synchrofacts we adapt the spike assignment with a non-uniform assignment distribution.In the next step, we apply various analysis methods to the artificial data to determine how synchrofacts affect the analysis results. Questions we are going to address are: a) does the presence of synchrofacts decrease the detectability of neuronal correlation activity, b) which type of correlation activity (pairwise or higher-order) is more diluted, and c) which synchrofact parameters (rate, correlation order, distribution over neurons, distribution over time) are mostly affecting the results. In order to do this we compare the analysis results from data with and without synchrofacts. This allows us to propose suitable methods of dealing with them.ReferencesMusial P, Baker S, Gerstein G, King E, Keating J (2002) Signal-to-noise ratio improvement in multiple electrode recording, Journal of Neuroscience Methods, Volume 115, Issue 1, Pages 29-43, ISSN 0165-0270, 10.1016/S0165-0270(01)00516-7Dann B, Michaels JA, Schaffelhofer S, Scherberger H (2016) Uniting functional network topology and oscillations in the fronto-parietal single unit network of behaving primates, eLife 2016;5:e15719, 10.7554/eLife.15719Essink S, Kleinjohann A, Barthélemy F, Ito J, Riehle A, Brochier T, Grün S (2019) Detection and Removal of Artefacts in Multi-Channel Electrophysiology Recordings, Bernstein Conference 2019, 10.12751/nncn.bc2019.0068Sprenger J (2014) Spatial Dependence of the Spike-Related Component of the Local Field Potential in Motor Cortex (Master’s thesis, RWTH Aachen).Torre E, Quaglio P, Denker M, Brochier T, Riehle A, Grün S (2016) Synchronous Spike Patterns in Macaque Motor Cortex during an Instructed-Delay Reach-to-Grasp Task, J.
