Sum of the Parts: Leveraging BIM to achieve effective delivery of mass customised housing

The UK housing market has, over the recent 5 years, experienced considerable economic pressures both from the market place and the construction sector. The need for an economic and mass produced housing type that specifically targets the market to achieve the balance for the need of affordability and the benefits of mass customisation is a key focus for delivery. This study sought to deliver a mass produced housing system that could also deliver a high level of customisation. Historically housing that has been mass produced to ensure affordability, has removed a high level of customisation to ensure that the final costs were controlled. This paper also examines the design factors that are integral to the process of delivery of affordable housing. In addition, it will observe the gaps between affordability and mass customisation of a modern method of construction delivered project and the move away from traditional methods of delivery, mapping the shift in the procurement of the design for such housing typologies

Using deep learning to understand and mitigate the qubit noise environment

Understanding the spectrum of noise acting on a qubit can yield valuable information about its environment, and crucially underpins the optimization of dynamical decoupling protocols that can mitigate such noise. However, extracting accurate noise spectra from typical time-dynamics measurements on qubits is intractable using standard methods. Here, we propose to address this challenge using deep learning algorithms, leveraging the remarkable progress made in the field of image recognition, natural language processing, and more recently, structured data. We demonstrate a neural network based methodology that allows for extraction of the noise spectrum associated with any qubit surrounded by an arbitrary bath, with significantly greater accuracy than the current methods of choice. The technique requires only a two-pulse echo decay curve as input data and can further be extended either for constructing customized optimal dynamical decoupling protocols or for obtaining critical qubit attributes such as its proximity to the sample surface. Our results can be applied to a wide range of qubit platforms, and provide a framework for improving qubit performance with applications not only in quantum computing and nanoscale sensing but also in material characterization techniques such as magnetic resonance.Comment: Accepted for publication, 15 pages, 10 figure

Investigating the 'latent' deficit hypothesis : age at time of head injury, executive and implicit functions and behavioral insight

This study investigated the 'latent deficit' hypothesis in two groups of frontotemporal headinjured patients, those injured prior to steep morphological and corresponding functional maturational periods for frontotemporal networks (≤ age 25), and those injured >28 years. The latent deficit hypothesis proposes that early injuries produce enduring cognitive deficits manifest later in the lifespan with graver consequences for behavior than adult injuries, particularly after frontal pathology (Eslinger, Grattan, Damasio & Damasio, 1992). Implicit and executive deficits both contribute to behavioral insight after frontotemporal head injury (Barker, Andrade, Romanowski, Morton & Wasti, 2006). On the basis of morphological and behavioral data, we hypothesised that early injury would confer greater vulnerability to impairment on tasks associated with frontotemporal regions than later injury. Patients completed experimental tasks of implicit cognition, executive function measures and the DEX measure of behavioural insight (Behavioral Assessment of the Dysexecutive Syndrome: Wilson, Alderman, Burgess, Emslie, & Evans, 1996). The Early Injury group were more impaired on implicit cognition tasks compared to controls that Late Injury patients. There were no marked group differences on most executive function measures. Executive ability only contributed to behavioral awareness in the Early Injury Group. Findings showed that age at injury moderates the relationship between executive and implicit cognition and behavioral insight and that early injuries result in longstanding deficits to functions associated with frontotemporal regions partially supporting the latent deficit hypothesis

Pittsburgh's Failed Industry Targeting Strategy of the 1960s

In the 1960's and early 1970's, public and private leaders made a substantial effort to promote Pittsburgh's existing transportation industry as a center for the emerging urban transportation market. The selection of the rapid transit industry for targeting in the 1960's purportedly addressed two issues. Despite national acclaim for its Renaissance redevelopment since World War II, the metropolitan region still needed an effective mass transportation system. Moreover, industrial development efforts had not substantially diversified the region's manufacturing base that still specialized in primary metals. Operating in the region's Renaissance tradition of a public and private partnership, corporate executives and public officials pursued a three-pronged strategy: build an innovative rapid transportation system for Allegheny County, use it as a showcase for testing and marketing rapid transit hardware of regional corporations, and promote the city as a center of the rapid transportation industry. They settled on Westinghouse's automated, rubber-tired vehicle running on a separate cement guideway, known locally as "Skybus," for the demonstration project and the region's mass transit solution. The mass transit plan and industry targeting strategy foundered by the early 1970's because leadership weakened in both poles of the partnership. The Westinghouse technology divided the corporate community, while populist political sentiment diminished the ability of the Democratic party's political machine to deliver key public decisions. The Pittsburgh case suggests that a successful industry targeting strategy may depend more on effective leadership and local politics than on the quality of the selection process and vigorous pursuit of traditional economic development programs in support of the targeted industry

The Chesapeake Bay and the Control of NOx Emissions: A Policy Analysis

Nitrogen oxide emissions not only affect air quality but have recently been found to be an important source of nitrate pollution in the Chesapeake Bay. This analysis examines the costs, emissions, source-specific and location-specific allocations of NOX emissions reductions and the ancillary ozone related health benefits under a range of policy scenarios. The paper includes analysis of three separate policies. The first is a detailed analysis of the effect on nitrate loadings to the Bay of command and control policies specified in the Clean Air Act and as part of the OTAG process. The second is a comparison of alternative scenarios for reducing NOX emissions that meet nitrate loading goals, with or without concern for reducing ozone concentrations and the health effects they cause. The third is a comparison of alternative approaches to allocate NOX emissions to meet NOX reduction and ozone exposure goals while capturing the ancillary effect on nitrate loadings. This last analysis focuses on the stake the Bay jurisdictions have in the outcome of negotiations over NOX trading programs being developed by EPA for reducing ozone in the Eastern U.S. With the primary focus on the Chesapeake Bay jurisdiction, all three analyses integrate the ancillary ozone benefits of policies to reduce nitrate pollution, including examination of how these ancillary benefits change under alternative meteorological episodes, and explore lower cost alternatives to current regulatory programs in both qualitative and quantitative terms. We find that the Chesapeake Bay benefits from efforts to reduce NOX emissions to meet the ambient air quality standard for ozone. Airborne NOX emission reductions slated to occur under the Clean Air Act in the Bay airshed will reduce nitrate loadings to the Bay by about 27 percent of the baseline airborne levels. The additional controls of NOX contemplated in what we term the OTAG scenario is estimated to result in an additional 20 percent reduction from this baseline. However, the paper's analysis of possible least cost options shows that the costs of obtaining such reductions can be significantly reduced by rearranging the allocation of emissions reductions to take advantage of source-type and locational considerations. In addition, we find that adding consideration of ancillary ozone-related health benefits to the picture does not alter any qualitative conclusions. Quantitatively, unless a link between ozone and mortality risk is assumed, the benefits are too small to affect the cost-saving allocations of NOX reductions. If the case for such a link can be made, the results change dramatically, with large overall increases in NOX reductions and a relative shift in controls to non-Bay states and utility sources. These specific effects are sensitive to the source-receptor coefficients linking NOX to ozone, however. Our analyses also suggest that the Bay jurisdictions have a stake in the outcome of the NOX trading debate -- that some trading designs can lead to better outcomes for these jurisdictions than others. Nevertheless, a common feature of cost-savings policies is that they both rearrange emissions reductions and, in the aggregate, reduce emissions less than a command and control system. Thus, some trading regimes result in significantly smaller loadings reductions (up to 25 percent smaller) than the command and control approach.
