1	Opticality and the Work of Morris Louis (1912-1962) McColm, Donna January 2007 (has links) Master of Philosophy / This thesis investigates the work of Morris Louis (1912-1962) in relation to ‘opticality’, a theory developed by the prominent American art critic Clement Greenberg. Between the late 1930s and 1950s, Greenberg developed a comprehensive argument concerning the opticality, or the optical illusion, of abstract painting. This theory influenced common approaches towards Abstract Expressionist painting during the 1940s and 1950s, culminating in Greenberg’s writing on ‘Colourfield’ painting in major texts of the 1960s such as ‘Louis and Noland’ (1960). Through research into the development of Morris Louis’ technique, including several of his major series as well as lesser known works, this thesis argues that our understanding of Louis’ work has been constricted by a narrow perception of the opticality of his 'stain' paintings, and explores Louis' technique in light of alternative interpretations of his work. art history modernism art criticism clement greenberg morris louis abstract expressionism opticality colour field

5	Vers le contrôle de l'alignement et de l'orientation : théorie et expérience / Towards control of molecular alignement and orientation : an experimental and theoretical approach Tehini, Ronald 13 December 2010 (has links) Cette thèse traite du contrôle et de la caractérisation de l'alignement et de l'orientation du point de vue théorique et expérimental. L'alignement d'une molécule linéaire consiste à obtenir une probabilité élevée de localisation de l'axe internucléaire symétrique autour de l'axe de polarisation du champ tandis que l'orientation privilégie un sens particulier le long du champ. L'orientation à l'aide d'impulsions bi couleur (2+1) non résonnantes est étudiée en détail et les conditions permettant d'obtenir une orientation efficace sont examinées. Un schéma bi couleur où la deuxième harmonique est en quasi-résonance avec un niveau vibrationnel de la molécule est également étudié. Cette technique présente l'avantage d'offrir un paramètre supplémentaire à savoir l'écart à la résonance qui peut être ajusté de manière à optimiser l'orientation moléculaire. Finalement une nouvelle technique expérimentale de détection de l'alignement moléculaire est présentée. Celle-ci permet une détection monocoup de l'alignement moléculaire sur une étendue temporelle jusqu'alors inégalée. / This thesis is about the control and characterisation of the alignment and orientation of molecules by ultra short laser pulses on a theoretical and experimental approach. Alignment corresponds to a symmetric angular distribution of the molecular axis peaked along the laser field axis, whereas orientation provides an asymmetric distribution favouring one spatial direction. Orientation by sudden two-colour (2+1) pulses is studied extensively for the non resonant case and conditions required for achieving significant orientation are explored. A second two-colour scheme, where the second harmonic is in quasi resonance with a vibrational level of the molecule, is also presented and discussed. The last technique has the advantage to offer the detuning of the laser frequency as an additional free parameter, which can be adjusted to enhance molecular orientation. A new experimental polarization imaging 2D technique for the detection alignment is also developed. Experimental results on single shot detection of molecular alignment achieved over an unprecedented temporal span are presented.
