Disparity of externalizing the internal architecture of creation
Thesis (S.M. in Art, Culture and Technology)--Massachusetts Institute of Technology, Dept. of Architecture, 2012."June 2012." Cataloged from PDF version of thesis.Includes bibliographical references (p. 90-92).The completion of any visual work is not an arrival, but furthered from the origin, the inner plane of perspective, which is so readily lent from the context of communicating the seemingly coded space from which I am inspired. The closest visual language within my grasp to elucidate my inquiries and to extend the physical works into a shared plane of seeing is through prose. This exploration of my research through the coupling of visual works, contextualized through the lens of allegory, furthers my understandings to communicate the inconsistencies in visual articulation. The prose in this case will not be treated as a literary work but as an extension of pre-conscious vision around which my practice has centered. When we read, we activate both a consciously aware state and the pre-conscious workings of our memories, this internal plane where perspective can be realized as a special architecture without form. While writing has the potential to motivate all of the senses, I use it in an attempt to restore the concrete to its original state; the internalized presence of its dimension. I am captivated by a kind of site I cannot clearly articulate with words or works, but there is a clarity, which may be revealed through the parallel pursuit that I will here explore. I would like to see this work as a map of multiple dimensions, a set of architectures that together elucidate a whole.by Matthew Everett Lawson.S.M.in Art, Culture and Technolog
CATRA: Interactive Measuring and Modeling of Cataracts
We introduce an interactive method to assess cataracts in the human eye by crafting an optical solution that measures the perceptual impact of forward scattering on the foveal region. Current solutions rely on highly-trained clinicians to check the back scattering in the crystallin lens and test their predictions on visual acuity tests. Close-range parallax barriers create collimated beams of light to scan through sub-apertures, scattering light as it strikes a cataract. User feedback generates maps for opacity, attenuation, contrast and sub-aperture point-spread functions. The goal is to allow a general audience to operate a portable high-contrast light-field display to gain a meaningful understanding of their own visual conditions. User evaluations and validation with modified camera optics are performed. Compiled data is used to reconstruct the individual's cataract-affected view, offering a novel approach for capturing information for screening, diagnostic, and clinical analysis.Alfred P.

Sustainable Blue-Green Infrastructure: A social practice approach to understanding community preferences and stewardship
© 2019 Blue-Green Infrastructure (BGI) is an approach to urban flood resilience, recognised globally and in international literature, that capitalises on the benefits of working with urban green-spaces and naturalised water-flows. Literature reveals BGI's sustainable functioning and benefits-provision depend on the behaviour of those who use it, therefore local stewardship is often proposed to support maintenance. However, there is a gap in understanding the requirements and behaviours of users, as well as their potential for developing stewardship behaviours, that is not addressed through traditional analysis approaches based around demographics. Therefore, this research used correlation analysis of survey data from two locations in the UK to explore the potential contribution of Social Practice Theory (SPT) to improve such understanding. Results show statistically significant correlation (better than 1%) between performance of practices associated with urban BGI and attitudes towards BGI stewardship, whereas demographic variables showed little correlation. Reflection on the practices demonstrates that this connection is traceable through the meanings people attach to their practices, the benefits of BGI spaces as material to those practices and their competencies in relation to existing and proposed stewardship practices. Practices, it is proposed, have embedded behaviours and attitudes that transcend locational and demographic factors. These findings imply in a wider context that, for any proposed or existing BGI, understanding associated practices would improve targeting of stewardship-engagement towards users with compatible meanings and competencies. Furthermore, sustainable design of BGI would benefit from consultation with all identified user-groups in order to understand existing and potential practices
Modeling, optimizing and simulating robot calibration with accuracy improvement
This work describes techniques for modeling, optimizing and simulating calibration processes ofrobots using off-line programming. The identification of geometric parameters of the nominalkinematic model is optimized using techniques of numerical optimization of the mathematicalmodel. The simulation of the actual robot and the measurement system is achieved by introducingrandom errors representing their physical behavior and its statistical repeatability. An evaluationof the corrected nominal kinematic model brings about a clear perception of the influence ofdistinct variables involved in the process for a suitable planning, and indicates a considerableaccuracy improvement when the optimized model is compared to the non-optimized one
Femto-photography: capturing and visualizing the propagation of light
We present femto-photography, a novel imaging technique to capture and visualize the propagation of light. With an effective exposure time of 1.85 picoseconds (ps) per frame, we reconstruct movies of ultrafast events at an equivalent resolution of about one half trillion frames per second. Because cameras with this shutter speed do not exist, we re-purpose modern imaging hardware to record an ensemble average of repeatable events that are synchronized to a streak sensor, in which the time of arrival of light from the scene is coded in one of the sensor's spatial dimensions. We introduce reconstruction methods that allow us to visualize the propagation of femtosecond light pulses through macroscopic scenes; at such fast resolution, we must consider the notion of time-unwarping between the camera's and the world's space-time coordinate systems to take into account effects associated with the finite speed of light. We apply our femto-photography technique to visualizations of very different scenes, which allow us to observe the rich dynamics of time-resolved light transport effects, including scattering, specular reflections, diffuse interreflections, diffraction, caustics, and subsurface scattering. Our work has potential applications in artistic, educational, and scientific visualizations; industrial imaging to analyze material properties; and medical imaging to reconstruct subsurface elements. In addition, our time-resolved technique may motivate new forms of computational photography.MIT Media Lab ConsortiumLincoln LaboratoryMassachusetts Institute of Technology.

Genome-Wide Screen of Three Herpesviruses for Protein Subcellular Localization and Alteration of PML Nuclear Bodies
Herpesviruses are large, ubiquitous DNA viruses with complex host interactions, yet many of the proteins encoded by these viruses have not been functionally characterized. As a first step in functional characterization, we determined the subcellular localization of 234 epitope-tagged proteins from herpes simplex virus, cytomegalovirus, and Epstein–Barr virus. Twenty-four of the 93 proteins with nuclear localization formed subnuclear structures. Twelve of these localized to the nucleolus, and five at least partially localized with promyelocytic leukemia (PML) bodies, which are known to suppress viral lytic infection. In addition, two proteins disrupted Cajal bodies, and 19 of the nuclear proteins significantly decreased the number of PML bodies per cell, including six that were shown to be SUMO-modified. These results have provided the first functional insights into over 120 previously unstudied proteins and suggest that herpesviruses employ multiple strategies for manipulating nuclear bodies that control key cellular processes

Evaluating the multiple benefits of a Blue-Green Vision for urban surface water management
A Blue-Green City aims to recreate a naturally-oriented water cycle while contributing to the amenity of the city by bringing water management and green infrastructure together. The Blue-Green approach is more than a stormwater management strategy aimed at improving water quality and providing flood risk benefits. It can also provide important ecosystem services, socio-cultural benefits and adaptability to future (uncertain) changes in climate and landuse. However, quantitative evaluation of the benefits, their spatial distribution and co-dependencies are not well understood. The Blue-Green Cities Research Consortium has adopted an interdisciplinary approach to quantitatively evaluate the benefits of Blue-Green infrastructure (BGI) and their relative significance. A new ArcGIS evaluation tool has been developed which can identify the spatial distribution of different benefits and normalise benefits onto a uniform scale. This allows the local impact of multiple benefit types, benefit dependencies and dis-benefits to be directly compared, helping decision makers to co-optimise the benefits from the outset of project planning. The tool was successfully piloted in 2014 in Portland, Oregon, a city with a Blue-Green Vision and extensive investment in green infrastructure, primarily to help reduce the number of combined sewer overflows and improve water quality. This paper also reports on the application of the benefit evaluation tool in Newcastle (UK). Here, hydrodynamic models have been developed to simulate pluvial flood inundation and the movement of water through BGI. An overland flow model has been integrated with the subsurface drainage network to handle discontinuous free surface and pressurised flows. This allows the simulation of mixed flows in pipes and realistic modelling of sewer outflow events. A hypothetical future is presented for a residential area of Newcastle where all pavements and back-alleyways have permeable paving and all gardens are greenspace. Modelling shows that the BGI provides temporary storage and helps alleviate the burden on the subsurface system. The Blue-Green Vision for Newcastle was developed by the Learning and Action Alliance (LAA), an open arrangement where participants create a joint understanding of a problem and its possible solutions based on rational criticism and discussion. The LAA encourages cooperation between a diverse range of stakeholders from different disciplines and backgrounds, including local authorities, major landowners, water companies, academia and environmental groups, and represents a novel approach to facilitate the negotiation of a Blue-Green Vision that addresses strategic objectives, public realm improvements and, not least, the management of urban surface water
Delivering And Evaluating The Multiple Flood Risk Benefits In Blue-Green Cities: An Interdisciplinary Approach
A Blue-Green City aims to recreate a naturally-oriented water cycle while contributing to the amenity of the city by bringing water management and green infrastructure together. The Blue-Green approach is more than a stormwater management strategy aimed at improving water quality and providing flood risk benefits. It can also provide important ecosystem services and socio-cultural benefits when the urban system is in a non-flood condition. However, quantitative evaluation of benefits and the appraisal of the relative significance of each benefit in a given location are not well understood. The Blue-Green Cities Research Project aims to develop procedures for the robust evaluation of the multiple functionalities of Blue-Green Infrastructure (BGI) components within flood risk management (FRM) strategies. The salient environmental challenge of FRM cuts across disciplinary boundaries, hence an interdisciplinary approach aims to avoid partial framing of the ongoing FRM debate. The Consortium, comprising academics from eight UK institutions and numerous disciplines, will investigate linkages between human behaviours and physical processes, and produce an urban flood model to simulate the movement of water and sediment through Blue-Green features. Individual and institutional agents will be incorporated into the model to illustrate how their behavioural changes impact on flooding and vice versa. A methodological approach for evaluating the interaction of urban FRM components within the wider urban system will be developed and highlight where, when and to whom a range of benefits may accrue from BGI and other flood management interventions under non-flood and flood conditions. Recognition of the compound uncertainties involved in achieving multiple benefits at scale will be part of the ongoing robust method of uncertainty evaluation. The deliverables will be applied to a chosen demonstration case study, Newcastle, UK, in the final year of the project (2015). This paper will introduce the Blue-Green Cities Research Project and the novel, interdisciplinary framework that is adopted to investigate multiple FRM benefits
