Full textThere is a paradox : modernity values are in crisis and, simultaneously me social carnavalisation is generalized. Everywhere, there is an uncontrolled laughter, and humoristic attitude is becoming me imposed mode of communication for me entire social world, and more particularly in firms. An evolution of me concept of laughter is noticeable in the working world ; Iaughter is forbidden in industrial companies, tolerated and encouraged in service companies, and obligatory in the start-up companies. This evolution is a translation of the position of laughter in society as a whole, and can be used as a social indication. Indeed, we find this evolution in several social periods showing an inflection in values which govem a society at a given time, and through that it inform US of a major social transformation, and for us here about me transition between modemity and postmodernity. Laughter allows this analysis through its specific characters, especially the neutral desire and a retum to sources. To burst out Iaughing means to shatter me basics, so that we reconstruct them differently and start again on new basis. Thus, laughter has this fundamental charactenstic to destroy and to build in the same movement, to be a fertilizing violence, in other words to laugh to death is equivalent to a rebirth

This thesis is the exploration of the natural and cultural environment through design. The natural landscape is a richly complex system reliant on interdependencies, change, and renewal. It is laden with multiple, even contradictory interpretations, yet it is one of intimate associations and often pastoral repose. Unlike the often static, simplistic order of the human environment, the natural environment is understood and enjoyed through formal and interactive relationships set in an emerging process of time. As such, a very positive reference for societies' state can be found in observing and transforming all evolving landscape that surrounds, nourishes, and defines us. The landscape, the "point of departure," becomes meaningful in its expression of the perpetual possibility of an occurrence, change or design. The vehicle for this investigation is a design projection for a small park in conjunction with the 1992 summer Olympic Games in Barcelona, Spain. The programmatic requirements are to supply temporary exhibit space for the Olympic/global ideal and to function as a formal and pedestrian link between the closed formal axis of the city and its extension to the Olympic Stadium. A strong design concern is the interpretation of the site as a temporal, spatial, and formal continuum of what existed before, the needs during the three week Olympic celebration, and its return to a daily routine as a new botanical garden. The first section is an elaboration of the relativistic character of the natural environment and its reference to both the process of design and the human experience. The second section describes the site in terms of landscape, its formal attributes and its place in geographic time. The third section describes the site in terms of memory, autobiographical and cultural time, the impact of man's relation to nature, and the specific plastic effects that it has had on the existing condition and form. The last section reveals the site in terms of change, or both the literal and lyrical passage of design. This part synoptically describes the temporal and formal configuration between what was, what is, and what might be.

Full textThe starting point of the project is an analysis of my own memories of elementary school. By drawing up the school from memory and analyzing selected spaces, I have investigated what I remember about the school building and why. The experience of many of the spaces I remember as exciting was about a discovery. An organization of spatial relationships in relation to direction led to an idea of a spatial structure and orientation based on two intersecting axes. Internal directions in relation to two intersecting axes have been analyzed by Palladios Villa Rotonda and Palazzo Della Torre. The directions from the analysis have been put in relation to the directions of the site. The the analysis resulted in two volumes with a passage between. Through the passage, the outer primary axis spans a wall in front of the school towards the road and the forest which constitutes the far border of the schoolyard. At the intersection of the axes is an inner courtyard, an vestibule for the buildings and the inner transverse axis. The inner axes provides a spatial structure around which rooms are organized. A pillar system helps to emphasize the directions in the building. A long vestibule surrounded by pillars leads from the entrances by the inner courtyard to the end point of the inner vestibule, a light room that extends through the floors. The northern part for the younger children has a staircase in front of the light room, the staircase recur for the older children in the southern part behind the light room. In connection with corridors and public areas, there are rooms with qualities from the analysis to be discovered.

Full textThe emergence of contemporary art implied many new ways of organizing and presenting art. The Museum of Forgetting is a small and nomadic contemporary art gallery with a strong idea-based foundation. This thesis describes, what the Museum of Forgetting is and how it is made through an Actor Network Theory-perspective. Because of the complexity in what Museum of Forgetting is, it is also relevant to examine how an organization such as Museum of Forgetting can be studied. The purpose of this thesis is to increase the understanding of non-traditional museums and contemporary art galleries by displaying the associations with and within the Museum of Forgetting. Previous studies of contemporary art have shown that one problem of contemporary art and its organization is the dependence on external financiers. Therefore, the critical perspective, characterizing contemporary art, can be difficult to achieve. Because of this, there is reason to study alternative organizational forms of presenting and organizing art. This thesis increases the understanding of non-traditional art galleries and museums by expanding what idea-based museums can be and by showing the importance of anti-groups for the creation of the identities of non-traditional art galleries and museums. The empirical and analytical findings show, that the Museum of Forgetting, through an ANT perspective, consists of two cycles. A small one, that is actualized at each exhibition and a large one, describing the identity of the Museum of Forgetting. The small cycle consists of the following units: the exhibition-idea, the artists, the artworks, the place and the financing. The large cycle consists of: exhibitions, the article ”Media without memory” and non-location as well as anti-groups. The unifying factors for both cycles are one obligatory passage point manifested in two spokespersons and one obligatory non-passage point manifested in the article Media without memory. The spokespersons strategies to maintain their position as obligatory passage point varies, depending on which actor to enrol in the network. In essence, according to my findings, the Museum of Forgetting should be understood as two cycles which are coalesced by an obligatory non-passage point, manifested in Media without memory and an obligatory passage point, manifested in two spokespersons, whose communications with the different parts of the cycles and identification of anti-groups, are essential for maintaining the homeomorphism of the Museum of Forgetting.

Full textSkin, which is a protective coating and the ultimate interface between humans and the environment, is constantly subjected to aggressive physical and chemical agents from the external environment. Despite its role as a barrier, skin is a route of entry for toxic or medicinal compounds that bring about the development of therapeutic or toxic effects, which may be local or systemic. The surface of the skin undergoes continuous gradients of humidity and temperature that induce profound changes in the structural and physiological condition of the skin. It is therefore necessary to take into account the influence of " spatial-temporal " variability of the characteristics of this external environment in the assessment of percutaneous absorption. Currently, the widely in vitro techniques used for percutaneous absorption studies are based on diffusion cells : static diffusion cell " Franz cell " or flow cells. The use of these devices has been validated in many instances. However, these devices do not allow us to explore and consider the influence of the characteristics of the external environment, particulary moisture and temperature, on percutaneous absorption. In this work we implement a new apparatus to examine the influence of external environmental conditions (humidity and temperature) on the percutaneous absorption. We then applied this technique to study the percutaneous penetration of vapors of a glycol ether : 2-Butoxyethanol (ex vivo study in humans). The last part of our work focuses on the development of an integrated package ready-to-use for studies of ex vivo percutaneous in human. This part stems from the fact that human skin after abdominoplasty is the gold standard in percutaneous penetration studies, however, ist availability and supply are often inadequate. In addition, the operations of preparation and characterization are require time and costs (staff, equipment, consumables etc. . . )

Full textThe adjoint mode of Algorithmic Differentiation (AD) is particularly attractive for computing gradients. However, this mode needs to use the intermediate values of the original simulation in reverse order at a cost that increases with the length of the simulation. AD research looks for strategies to reduce this cost, for instance by taking advantage of the structure of the given program. In this work, we consider on one hand the frequent case of Fixed-Point loops for which several authors have proposed adapted adjoint strategies. Among these strategies, we select the one introduced by B. Christianson. We specify further the selected method and we describe the way we implemented it inside the AD tool Tapenade. Experiments on a medium-size application shows a major reduction of the memory needed to store trajectories. On the other hand, we study checkpointing in the case of MPI parallel programs with point-to-point communications. We propose techniques to apply checkpointing to these programs. We provide proof of correctness of our techniques and we experiment them on representative CFD codes

Full textIn this thesis we propose novel algorithms for video analysis. The first contribution of this thesis is in the domain of video segmentation wherein the objective is to obtain a dense and coherent spatio-temporal segmentation. We propose joining both spatial and temporal aspects of a video into a single notion Fiber. A fiber is a set of trajectories which are spatially connected by a mesh. Fibers are built by jointly assessing spatial and temporal aspects of the video. Compared to the state-of-the-art, a fiber based video segmentation presents advantages such as a natural spatio-temporal neighborhood accessor by a mesh, and temporal correspondences for most pixels in the video. Furthermore, this fiber-based segmentation is of quasi-linear complexity w.r.t. the number of pixels. The second contribution is in the realm of multiple object tracking. We proposed a tracking approach which utilizes cues from point tracks, kinematics of moving objects and global appearance of detections. Unification of all these cues is performed on a Conditional Random Field. Subsequently this model is optimized by a combination of message passing and an Iterated Conditional Modes (ICM) variant to infer object-trajectories. A third, minor, contribution relates to the development of suitable feature descriptor for appearance matching of persons. All of our proposed approaches achieve competitive and better results (both qualitatively and quantitatively) than state-of-the-art on open source datasets

Full textChemical synaptic transmission enables information flow in the brain between neurons. This process critically depends on neurotransmitter release, which is governed by calcium-regulated exocytosis. The speed, efficacy, and reliability of synaptic transmission are critically affected by the spatiotemporal calcium dynamics and the distance that Ca2+ ions travel to reach the vesicular sensor. We hypothesize that variations in the nanoscale organization of VGCCs and synaptic vesicles contribute to the diversity of synaptic function. However, direct experimental observation of this fundamental second messenger system is not currently possible due to its submillisecond timescale and submicron spatial scale. Therefore, we have taken a computational approach to study the spatiotemporal dynamics of Ca2+ -triggered vesicle fusion. In the course of this work, we have adapted classical point process methods and generative models to interpret differences in channel-vesicle topographies in the weak and strong cerebellar synapses. The function impact of inferred arrangements was further explored using Monte Carlo (MC) simulations of calcium dynamics and vesicular fusion, with experimentally constrained parameters. We found that small VGCC clusters with tight coupling distance between calcium channels and vesicle can account for the functional characterises of the strong synapses, while the arrangement where VGCCs are loosely coupled and excluded from the vicinity of the vesicle can reproduce the behaviour of weak synapses. Thus suggesting that nanoscale distribution of VGCCs and synaptic vesicles differs among synapses and is a key factor underlying functional synaptic diversity. Along the way, we have delineated critical factors and parameters for simulations of vesicle release time course and probability. We found that among the critical factors are the stochastic opening of the calcium channels, affinity of fixed endogenous buffer and vesicles sensor, as well as duration of calcium entry. Month-long particle-based simulations motivated our efforts to explore novel analytical methods inspired from mean-field first-passage methods. We have established a probability distribution of a single calcium ion being bound to the sensor. The model was validated using particle based Monte Carlo simulations. Because of the nature of the analytical method we were able to simulate the binding of Ca2+ ions to a sensor between nanoseconds to 100’s milliseconds of diffusion-reaction time. The rapid calculations using the analytical method were much more amenable to parameter searching and understanding how on and off-rate constants of the sensor and competing buffers interacted. These simulations, for example, showed clearly that the off-rate constant of the buffer critically influenced the time course of the sensor occupancy on the microsecond and millisecond time scale for experimental-like parameters, and in turn also define the time course of vesicle fusion. Once we surpass some of the initial hurdles, this novel approach will represent the first analytical-based approach that predicts spatial-temporal profile Ca2+ dynamics and how it drives vesicle fusion. We aspire to use this approach as a building block for a new, efficient diffusion reaction simulator of vesicle release, enhancing precision and accuracy while significantly reducing computational time
