Algorithms for the application of Hartmann-Shack wavefront sensors in ophthalmology
… of procedures and algorithms for applications of Hartmann-Shack wavefront sensors in ophthalmology. Two compact systems were built to do measurements of the entire optical system of the human eye. Automatic pre-correction modules were integrated to compensate a sphere of -11.25 dpt to 3.25 dpt and …

A thesis on the genitive case in Hartmann von Aue's Armer Heinrich
… of separately. For this purpose I selected Hartmann von Aue's "Armer Heinrich," a Mid. High German poem written in the 13th century. It is a truly scholarly production, and its language can safely be considered the best German of the author's time.

A CMOS-based Hartmann-Shack Sensor for Real-Time Adaptive Optical Applications
… is the need for a sensor and an actuator. The Hartmann-Shack wavefront sensor uses the displacement of spots in the focal plane of a lenslet array for subsequent calculation of the wavefront. The bandwidth of current sensors is mostly limited by software processing of the focal plane image to …

"The Nuremberg Chronicle and Its Readers: The Reception of Hartmann Schedel's ""Liber Cronicarum"""
While the Liber cronicarum had many potential uses, marginalia and other signs of use show that certain aspects of the Liber cronicarum inspired the most substantial reactions: its accounts of history and geography, its presentation of religious material, and its depiction of the Holy Roman …

The Portrayal of zorn in Hartmann von Aue’s Arthurian Romances and in Wolfram von Eschenbach’s Parzival
This thesis examines the portrayal of zorn in Hartmann von Aue’s Erec and Iwein, and in Wolfram von Eschenbach’s Parzival. The opening chapter provides an insight into the meaning of zorn and examines the physical signs, symptoms, and symbols of anger, as well as its theological, moral, and social …

An enquiry into Nicolai Hartmann's appreciation of Nietzsche's axiology
… has done more in this respect than Nicolai Hartmann who considers Friedrich Nietzsche to have been his immediate predecessor. Yet Hartmann is not well known in the English-speaking world. The following study represents an attempt to explain Hartmann's position in epistemology, ontology and …

Hochpräzise drei-dimensionale Bestimmung optischer und biomechanischer Eigenschaften der menschlichen Hornhaut
… das auf der Methode der Wellenfrontanalyse nach Hartmann-Shack basiert. Die kompakte, für den klinischen Einsatz aufgebaute Meßapparatur bildet die Oberfläche der Hornhaut unter Beachtung der Phasenbeziehung auf einem Hartmann-Shack-Sensor ab. Die Phasenbeziehung, die sich auch als Wellenfront …

The sins of the sons: a comparative analysis of guilt, atonement and redemption in Kafka's Die Verwandlung and Thomas Mann's Der Erwahlte with reference to Hartmann von Aue's Gregorius
… linked by their respective relationships to Hartmann von Aue‟s Gregorius. Bearing in mind this background source, it seeks to illuminate the complex issues of guilt, atonement and redemption addressed in both texts, through their consideration within a familial context. Like Hartmann‟s „good …

Inheritance of Resistance to Tomato Spotted Wilt Virus in Lettuce (Lactuca Sativa L.)
… have been no reports of resistance in lettuce. Hartmann (personal communication) undertook a preliminary screening program for TSWV resistance and found six lines of lettuce 'Tinto', PI 167128, PI 342510, PI 342517, PI 342522, and PI 342526 that showed less infection with TSWV than the …

Coherence-Gated Wave-Front Sensing in Strongly Scattering Samples
… is presented. This method combines Shack-Hartmann wave-front sensing and phase shifting interferometry (PSI). It employs virtual lenses to mimic the function of a conventional Shack-Hartmann sensor. The use of a modal estimation algorithm allows an approximation of the measured wave-front …

Magnetohydrodynamic Heat Transfer for Fusion Energy
… S/m), it is only possible to achieve high enough Hartmann numbers for partial flow relaminarization in the experiment. The flow loop allows for qualitative characterization of behavior in regions of steep magnetic field gradients and transitional flows . This thesis uses existing liquid metal …

Alis volat propriis: pathways, challenges and strategies for Australian women in elite-level sport leadership
… (e.g., Acosta & Carpenter, 2010; Cameron, 1996; Hartmann-Tews & Pfister, 2003; McKay, 1997; Robertson, 2010). Researchers have identified barriers that have inhibited women’s progression to elite-level roles. Little is known, however, about the pathways or experiences of women who do advance to …

Multi-Scale Model of the Stability of a Laterally Heated Liquid Bridge Under the Influence of an Axial Magnetic Field
… is obtaining sufficient resolution of the thin Hartmann boundary layers, which form perpendicular to the magnetic field at the solidification and melting fronts. A secondary challenge is due to the segregation of the flow into a strong convection cell near the free surface, and a nearly stagnant …

Assembly and proving of a wave front sensing confocal Scanning Laser Ophthalmoscope
… adaptive-optical cSLO. In this work a Shack-Hartmann wave front sensor was implemented into a slightly modified Heidelberg Retina Tomograph (HRT) and aberrations of model eyes were measured. Results show that this system is now ready for testing on living eyes.
