1	Binocular interactions in human vision Midgley, Caroline Ann January 1998 (has links) Early visual processing is subject to binocular interactions because cells in striate cortex show binocular responses and ocular dominance (Hubel & Weisel, 1968). The work presented in this thesis suggests that these physiological interactions can be revealed in psychophysical experiments using normal human observers. In the region corresponding to the blind spot, where binocular interactions differ from areas of the visual field which are represented by two eyes, monocular contrast sensitivity is increased. This finding can be partially explained by an absence of normal binocular interactions in this location (Chapter 2). A hemianopic patient was studied in an attempt to discover whether the effect in normal observers was mediated by either a mechanism in striate cortex or via a subcortical pathway. However, the results were unable to distinguish between these two explanations (Chapter 3).In a visual search task, no difference in reaction time was observed for targets presented to the region corresponding to the blind spot compared with targets presented to adjacent binocularly represented areas of the visual field. Since performance was unaffected by the monocularity of the region corresponding to the blind, pop-out for orientation may be mediated beyond striate cortex where cells are binocularly balanced (Chapter 5). Further support for this contention was provided by studies of orientation pop-out in central vision which found that dichoptic presentation of stimuli did not affect the degree of pop-out obtained and that in general, visual search for a target based solely on eye of origin is impossible (Chapter 6). However, a task that measured orientation difference sensitivity more directly than the search experiments, found that thresholds were higher for dichoptically presented stimuli. This suggests the involvement of neurons that receive a weighted input from each eye. A model of orientation difference coding can account for the results by assuming that the range of inhibition across which orientation differences are coded is narrower for dichoptic stimuli leading to a greater resolvable orientation difference (Chapter 7). 150 Blind spots; Contrast sensitivity

4	Real-time pro-active safety in construction Allread, Benjamin Scott 18 May 2009 (has links) Collisions between personnel on foot and heavy equipment or materials on a construction site can be characterized as a contact collision. These types of incidents are a common occurrence on a work site. Technology is needed to improve work zone safety by alerting workers that are in danger of collisions pro-actively and in real-time. Developing this technology may assist in collecting previously un-recorded data on "near-misses" (close-calls). An approach is presented in this paper that is based on wireless radio frequency technology to alert workers in real-time when they are in danger. Various experiments are described that have been conducted in order to gain better understanding of the technology's potential, including measuring equipment blind spots and alert (or safety) zones. Blind spots areas are measured for six common construction vehicles to help determine the required (or minimum) alert distance (safety zone) for the equipment. A computer program was developed in-house to automatically calculate the percentage of blind spots on 2-dimensional planes and in the overall 3-dimensional volume. The blind spots results directly indicate the necessary safety zones for the equipment. The proximity device results show that technology demonstrated the capability of collecting important safety data while pro-actively detecting hazardous situations and warning workers and equipment operators during imminent potential hazardous events. Furthermore, the presented research can lead to improve the overall safety performance in construction and elsewhere through improved learning and education by providing relevant information to decision makers at all levels.

5	"Ich dichte in die wüste Zeit" - Ich-Konstruktionen in der Lyrik der deutschsprachiger Schriftsteller_innen Israels / "I am writing into deserted times" - Constructions of the I in the German poetry of the Israeli writers Netti Boleslav and Jenny Aloni Poppe, Judith 27 August 2015 (has links) Die vorliegende Arbeit untersucht eine in der bisherigen Literaturgeschichtsschreibung unbeachtete Literatur – die deutschsprachige Literatur Israels. Exemplarisch wird dafür die Lyrik zweier Autor_innen, Jenny Aloni und Netti Boleslav, in den Blick genommen. Jenny Aloni und Netti Boleslav emigrierten Ende der 1930er Jahre aus dem nationalsozialistischen Deutschland bzw. Prag nach Israel, fanden dort eine neue Heimat und verfassten bis zu ihrem Tod in den 1980er bzw. 1990er Jahren in deutscher Sprache Lyrik und Prosa. Leben und Werk der Autor_innen werden in der Arbeit auf der Basis von Dokumenten wie Tagebüchern, Briefen und unveröffentlichten Manuskripten rekonstruiert, die hier zum Teil erstmals aus dem Nachlass gezogen und in die literarische Öffentlichkeit eingebracht werden. Die hermeneutische Untersuchung der Gedichte in ihrem poetischen Eigenwert wird durch die Einbeziehung poststrukturalistisch-kulturwissenschaftlicher Methoden ergänzt. Die Studie rückt die Ich-Konstruktionen in den Fokus – sowohl die der empirische Autor_innen als auch die der literarischen Ichs – und verfolgt damit die Fäden an unterschiedliche Zeiten und Orte zurück, in und an denen die Literatur ihre Spuren hinterlassen hat. Auf der Basis der Analysen wird die untersuchte Literatur, basierend auf Konzepten von Deleuze/Guattari und Kühne, schließlich als „Kleine Zwischenliteratur“ bezeichnet. Die Literatur Alonis und Boleslavs erscheint in Spannungsfeldern zwischen deutschem und israelischem Literaturbetrieb, mäandert zwischen Einheiten wie Böhmen, dem nationalsozialistischen und postnationalsozialistischen Deutschland, dem Staat Israel, der CSSR aber auch zwischen „jüdischer“ und „israelischer“ Literatur, deutscher Popkultur, Naturlyrik und zionistischer Geschichtsschreibung. Die Literaturgeschichte hat diese einmalige Positionierung der deutschsprachigen Literatur bisher nahezu unbeachtet gelassen. Mit der vorliegenden Arbeit wird dieser blinde Fleck geschlossen. Um dieser Literatur ihr Zuhause zu geben, so die abschließende Forderung der Arbeit, sind transdisziplinär und transnational Überlegungen anzustellen, wie die Literaturwissenschaft den Schnittmengen zwischen diesen zwei Literaturgeschichten institutionell und konzeptionell gerecht werden kann. 100 Deutschsprachige Literatur Israels Deutschsprachige Lyrik Israels Lyrik Israel Netti Boleslav Jenny Aloni Benno Fruchtmann Mirjam Michaelis Werner Bukofzer Sechstagekrieg Literatur Sechstagekrieg Lyrik Holocaust Shoah Eine kleine Literatur Lyrik nach der Shoah Literatur nach der Shoah Jerusalem Lyrik Jerusalem Literatur Alte Heimat Lyrik Israelische Lyrik Leerstellen deutsche Literaturgeschichte Max Brod Krieg 1948 Israel Literatur Krieg 1948 Israel Lyrik deutsche Literatur Israel Jeckes Israel Literatur Jekkes Israel Literatur Zwischenliteratur Theodizee Literatur Israeli literature German language Israeli poetry German poetry Israel Netti Boleslav Jenny Aloni Benno Fruchtmann Mirjam Michaelis Werner Bukofzer Six Day War literature Six Day War poetry Holocaust Shoah poetry after the Shoah literature after the Shoah Jerusalem poetry Jerusalem literature Israeli poetry blind spots German history of literature Max Brod war 1948 Israel literature war 1948 Israel poetry Jekkes literature Israel Jekkes poetry Israel Theodizee literature Philosophie (PPN619942320)
