Abstract This article addresses claims made about the impact of intermedial theatre with reference to examples of contemporary practice. In particular it makes references to Brecht in this context and differentiates between Brechtian politics and aesthetics. The professed aim of intermedial practitioners to dislocate the bearings of experiencers of their work and to afford new perceptions by means of a radical play between mediums appears to resonate, at the level of principles of composition, with Brecht’s “radical separation of the elements.” However, at the level of politics, Brecht’s drama sought a broader understanding of isolated individuals by inviting audiences to see their experience in connection with a total historical process. But, regarding the Marxist trajectory in which Brecht’s practice was located, the context changed markedly post-1968, and beyond recognition post-1989. The article thus proposes that a new formulation is required of the impacts of new perceptions elicited by contemporary intermedial practices and ends with a brief consideration of Rancière’s account of the clash of heterogeneous elements in intermedial practice.

Abstract. In situ soil moisture data from 122 stations across the United States are used to evaluate the impact of a new bare ground evaporation formulation at ECMWF. In November 2010, the bare ground evaporation used in ECMWF's operational Integrated Forecasting System (IFS) was enhanced by adopting a lower stress threshold than for the vegetation, allowing a higher evaporation. It results in more realistic soil moisture values when compared to in situ data, particularly over dry areas. Use was made of the operational IFS and offline experiments for the evaluation. The latter are based on a fixed version of the IFS and make it possible to assess the impact of a single modification, while the operational analysis is based on a continuous effort to improve the analysis and modelling systems, resulting in frequent updates (a few times a year). Considering the field sites with a fraction of bare ground greater than 0.2, the root mean square difference (RMSD) of soil moisture is shown to decrease from 0.118 m3 m−3 to 0.087 m3 m−3 when using the new formulation in offline experiments, and from 0.110 m3 m−3 to 0.088 m3 m−3 in operations. It also improves correlations. Additionally, the impact of the new formulation on the terrestrial microwave emission at a global scale is investigated. Realistic and dynamically consistent fields of brightness temperature as a function of the land surface conditions are required for the assimilation of the SMOS data. Brightness temperature simulated from surface fields from two offline experiments with the Community Microwave Emission Modelling (CMEM) platform present monthly mean differences up to 7 K. Offline experiments with the new formulation present drier soil moisture, hence simulated brightness temperature with its surface fields are larger. They are also closer to SMOS remotely sensed brightness temperature.

<p>Architects use media such as drawings and models to test and better understand their designs. These media are frequently scaled for convenience and reduced to two dimensions for clarity; however, in relying on these methods, the direct and visceral experience of inhabiting space is neglected. Phenomenologists such as Juhani Pallasmaa point out that this problem is exacerbated by the picture plane. The flat page or screen acts as an impenetrable window, excluding the viewer from a truly embodied appreciation of the designed spatial qualities.  This research investigates the use of virtual reality (VR) as a tool for conceiving architecture without alienating the designer from the user’s perspective. It is suggested that the holistic and subjective approach of immersive media is a necessary complement to the more abstracted and objective views of architectural tradition: plan, section, and elevation. The recent availability of consumer-grade VR allows the testing of this opportunity without many of the technological limitations of research done in the 1990’s. This research aims to describe tendencies of VR design and thus guide the incorporation of immersive technologies into contemporary practice.  To study the impact of VR, a real-time engine is used to develop an interactive program which allows the modelling of conceptual designs while immersed within them. Its efficacy is studied with three groups (architecture students, architects, and members of the public) from which quantitative and qualitative data is collected. By identifying the unique benefits of such tools, it is proposed how each group could make good use of the technology and extend the abilities of their existing workflows.</p>

The Impact

Although recent work in Decision-Based Design (DBD) recognizes the need for an enterprise perspective in which the expected net revenue is the primary driver of utility, for the overwhelming majority of contributions in the DBD literature, the emphasis in the problem formulation is exclusively on the design artifact. This formulation of DBD problems is too narrow in scope, in that the use of resources during the design and development phase is overlooked. This omission makes it impossible to consider tradeoffs between the design artifact and the design process. In this paper, we reformulate the DBD problem in terms of the design process rather than the artifact. This new formulation more accurately represents the tradeoffs under consideration in an enterprise context and simplifies to the traditional DBD formulation if design phase resource use is assumed to be negligible. As a first step towards establishing this new formulation, a simple example problem is introduced and solved. The example involves a choice between two concepts, with an option to perform an analysis to reduce the uncertainty. Although several simplifying assumptions are made in this work that are not likely to apply in practical design problems, the intent of this work is to qualitatively explore the impact of relaxing some of the assumptions made implicitly in previous work in DBD. These assumptions include ignoring the costs of the design phase as well as the assumption that the value of a particular information source is independent of the ability to gain additional information from subsequent analyses. Solving the design process decision problem in this manner confirms the intuition that an analysis is worth performing only when the cost is low, the quality is high, and there is significant overlap in the predicted utility of the two concepts. In addition, this new DBD formulation is compared to related work in information economics, and we show that the new DBD formulation provides a more comprehensive model of the problem when a sequence of information sources is available.

Force Displacement

This paper presents a new formulation for elastic-plastic contact in the normal direction between two round surfaces that is solely based on material properties and contact geometries. The problem is formulated as three separate domains: the elastic regime, mixed elastic-plastic behavior, and unconstrained (fully plastic) flow. Solutions for the force-displacement relationship in the elastic regime follow from Hertz’s classical solution. In the fully plastic regime, two assumptions are made: that there is a uniform pressure distribution and that there is conservation of volume. The force-displacement relationship in the intermediate, mixed elastic-plastic regime is approximated by enforcing continuity between the elastic and fully plastic regimes. Transitions between the three regimes are determined based on empirical quantities: the von Mises yield criterion is used to determine the initiation of mixed elastic-plastic deformation, and Brinell’s hardness for the onset of unconstrained flow. Unloading from each of these three regimes is modeled as an elastic process with different radii of curvature based on the regime in which the maximum force occurred. Simulation results explore the relationship between the impact velocity and coefficient of restitution. Further comparisons are made between the model, experimental results found in the literature, and other existing elastic-plastic models.

Abstract. In the SURFEX/ISBA-Crocus multi-layer snowpack model, the snow microstructure has up to now been characterised by the grain size and by semi-empirical shape variables which cannot be measured easily in the field or linked to other relevant snow properties. In this work we introduce a new formulation of snow metamorphism directly based on equations describing the rate of change of the optical diameter (dopt). This variable is considered here to be equal to the equivalent sphere optical diameter, which is inversely proportional to the specific surface area (SSA). dopt thus represents quantitatively some of the geometric characteristics of a porous medium. Different prognostic rate equations of dopt, including a re-formulation of the original Crocus scheme and the parameterisations from Taillandier et al. (2007) and Flanner and Zender (2006), were evaluated by comparing their predictions to field measurements carried out at Summit Camp (Greenland) in May and June 2011 and at Col de Porte (French Alps) during the 2009/10 and 2011/12 winter seasons. We focused especially on results in terms of SSA. In addition, we tested the impact of the different formulations on the simulated density profile, the total snow height, the snow water equivalent (SWE) and the surface albedo. Results indicate that all formulations perform well, with median values of the RMSD between measured and simulated SSA lower than 10 m2 kg−1. Incorporating the optical diameter as a fully fledged prognostic variable is an important step forward in the quantitative description of the snow microstructure within snowpack models, because it opens the way to data assimilation of various electromagnetic observations.

Abstract The wide variety of silicon materials used by various groups to investigate LeTID make it difficult to directly compare the defect concentrations (Nt) using the typical normalised defect density (NDD) metric. Here, we propose a new formulation for a relative defect concentration (β) as a correction for NDD that allows flexibility to perform lifetime analysis at arbitrary injection levels (Δn), away from the required ratio between Δn and the background doping density (Ndop) for NDD of Δn/N dop = 0.1. As such, β allows for a meaningful comparison of the maximum degradation extent between different samples in different studies and also gives a more accurate representative value to estimate the defect concentration. It also allows an extraction at the cross-over point in the undesirable presence of iron, or flexibility to reduce the impact of modulation in surface passivation. Although the accurate determination of β at a given Δn requires knowledge of the capture cross-section ratio (k), the injection-independent property of the β formulation allows a self-consistent determination of k. Experimental verification is also demonstrated for boron-oxygen related defects and LeTID defects, yielding k-values of 10.6 ± 3.2 and 30.7 ± 4.0, respectively, which are within the ranges reported in the literature. With this, when extracting the defect density at different Δn ranging between 1014 /cm3 to 1015 /cm3 with Ndop = 9.1 ×1015 /cm3, the error is less than 12% using β, allowing for a greatly improved understanding of the defect concentration in a material.
