Krystiana Lupy teatr transparentny. Uwagi o funkcjach przezroczystości w scenografii teatralnej

The article is an attempt to describe some of the most important transparent constructions in Krystian Lupa’s theatre and to explain their functions. In the text, I focused on the main and most frequently repeated transparent elements of the scenography; prisms (which fulfil the role of internal frames), transparent walls (places where actors are peeping over), and bars and grids which suggest closing some space off or isolating the actors.

Experimental Measurement of the Accumulated Heat from the Operation System of the Heating in a Building with a Lightweight Envelope

Abstract The heating and cooling of buildings with large-scale ceiling systems nowadays is widely used in traditional as well as in new, low-energy buildings. This type of system is being employed in a building of the Civil Engineering Faculty (FCE), Slovak Technical University, in Bratislava. The building’s refurbishment in 2010 included the complete replacement of the building’s envelope. The replacement is a lightweight facade with a high percentage of transparent construction. Due to the differences between the type of envelope and the heating system, the operation of the heating system frequently causes thermal discomfort, especially during warm spring or autumn days. The aim of the measurements was to evaluate the control of the operation of the heating output, the appropriateness of the location of sensors measuring the outdoor temperature and possible improvement of the current control system to improve the heating system’s quality.

Quantitative scenario design with Bayesian model averaging: constructing consistent scenarios for quantitative models exemplified for energy economics

BackgroundScenario design is currently not a standardised process. The formulation of storylines representing different dimensions (for example economic or societal developments) demands an investigation of assumption compatibility, coherence, and consistency. Scenario techniques that use expert opinion as the sole information source are particularly appropriate for personal decisions. Contexts where scenarios serve as decision support on a societal level—for example in political decision-making—benefit from unbiased, fact-depicting, multi-dimensional information that is available in statistical data.MethodsThe presented approach uses the well-established method of Bayesian model averaging for the formulation of consistent, transparent, and intuitively understandable quantitative scenario assumptions. These assumptions are used in quantitative models to produce outlooks and forecasts. Illustrated by the example of quantitative energy models used to investigate developments of the energy system by scenario technique, the approach contrasts with other scenario methods. Bayesian model averaging (BMA) is a method that allows for an evaluation of both system relation stability in terms of observable co-evolvement of phenomena in the past and of future system states of interest based on expert opinion where past evolvements serve as a point of reference.ResultsThe results are scenarios assessable with respect to (1) the consistency of scenario assumptions in terms of statistical confirmation, (2) the suitability of a quantitative model to represent the scenario, and (3) the statistical uncertainty of the scenario for a given quantitative model. A transparent scenario construction process results in traceable assumption documentation (an exemplary communication is provided in the Appendix). Perhaps, the most important novelty of the approach is the possibility of communicating to decision-makers the associated uncertainty in easily understandable terms. The distinction between provable possible assumptions (based on statistical evidence) and hypothetical assumptions is a novelty and significantly improves the aptitude of scenario study recipients to evaluate scenarios on their part.ConclusionsBMA provides the possibility for decision-makers (and all recipients of outlooks based on scenario technique) to trace back results to assumptions and provide an evaluation of these assumptions in terms of statistical confirmation. As such, the approach adds to the currently limited methodological diversity in scenario construction techniques.

Влияние конструкции прозрачного покрытия на эффективность термообработки бетона в опалубочных формах с использованием солнечной энергии

The shuttering forms, equipped by inventory frames with transparent cover, are the simple solar energy equipment for heat treatment of reinforced concrete elements during their manufacturing at the plants. They are similar with solar collectors by their design and thermal-physical processes, taking place in them, with difference that the heat sink is hardening concrete. The research results of influence of transparent cover construction on efficiency of concrete heat treatment in shuttering forms with employment of solar energy in different climatic conditions are given in the article. The volume of energy, consumed and lost by concrete during its direct heating by solar energy in the simple solar energy equipment like solar collector, depends on the transparent cover construction. Under other same conditions, the increase of cover layers affects its transparency, which is characterized by the solar energy transmittance, but in this case, it reduces heat losses in environment, which are characterized by the coefficient of heat losses through transparent cover. One-layer and two-layer transparent covers are chosen for assessment of efficiency of heat treatment of concrete elements, because the increase of cover layers more than two reduces intensity of the heat sink warming in the daytime and it is accepted by scientists in solar energy field as pointless. Optimal number of transparent material layers in cover construction is determined based on energy assessment in result of thermal- physical calculation and experimental research. The economic losses for production of transparent cover due to the increase of its layers are taken into account in addition with energy assessment

Integrated Supplier Selection Framework in a Resilient Construction Supply Chain: An Approach via Analytic Hierarchy Process (AHP) and Grey Relational Analysis (GRA)

Construction supply chain management is a unique and problematic issue within the construction industry due to its inevitable external risks and variations. The resilience capability of a supplier is of significance in supplier selection; a supplier selected in the context of a resilient construction supply chain (RCSC) is referred to in this research as a “resilient construction supplier”. This paper proposes a supplier selection framework tailored to effective information integration for supply chain management. The proposed framework works by integrating building information modeling (BIM) and a geographic information system (GIS) in a RCSC. BIM and GIS together provide highly transparent construction material information, enhanced supply chain status visualization, and workable access information for supplier selection. Supplier performance is evaluated via seventeen resilient criteria under a combined methodology consisting of the analytic hierarchy process (AHP) and grey relational analysis (GRA); AHP and GRA weigh the criteria and rank the suppliers respectively. By varying the weightings given to each criterion, sensitivity analysis was conducted to identify the criteria of resilience which impact the selection priorities of suppliers. An illustrative example is also provided to show the overall process of the proposed framework.

3D Product Development for Loose-Fitting Garments Based on Parametric Human Models

Researchers and commercial suppliers worldwide pursue the objective of achieving a more transparent garment construction process that is computationally linked to a virtual body, in order to save development costs over the long term. The current aim is not to transfer the complete pattern making step to a 3D design environment but to work out basic constructions in 3D that provide excellent fit due to their accurate construction and morphological pattern grading (automatic change of sizes in 3D) in respect of sizes and body types. After a computer-aided derivation of 2D pattern parts, these can be made available to the industry as a basis on which to create more fashionable variations.

МЕХАНИЗМЫ ЭКОНОМИЧЕСКОГО СТИМУЛИРОВАНИЯ ЗЕЛЕНЫХ СТАНДАРТОВ СТРОИТЕЛЬСТВА И ЭКСПЛУАТАЦИИ ОБЪЕКТОВ НЕДВИЖИМОСТИ

Sustainable development of the construction industry of the country is focused on permanent growth of its energy and resource efficiency, and involves the introduction of the practice of design and economic analysis of the eco-oriented principles of assessment, monitoring and management. Reform in the field of construction pricing and revaluation of the key principles for determining the cost of construction products should be aimed at improving the existing arrangements for the assessment of energy costs and environmental damage in the construction, integration at the legislative level in developing resource method of determining the estimated cost of construction, the establishment of transparent and effective environmental auditing mechanism construction. The development of the construction industry market in the aspect of environmental conservation is one of the most urgent problems and suggests improvement and analysis of methods for pricing for construction products, the search for new solutions eco-oriented, which in turn implies a transition to green building.

The Discursive Construction of Journalistic Transparency

Drawing on Bourdieu's field theory, this study explores how journalistic doxa and cultural capital come to be discursively formed. The study culls references to journalistic transparency from a broad range of US journalism trade publications and sites from 1997 to 2015 in order to examine the discursive construction of transparency within the journalistic field. The analysis focuses on what members of the journalistic field in the United States mean by transparency and how transparency is or is not discursively legitimized. Implications for field theory are considered.

Dramatically Enhanced Performance of Flexible Micro‐VCSELs via Thermally Engineered Heterogeneous Composite Assemblies

elevated temperatures. [ 13,19,20 ] Development of novel integration pathways to allow implementation of VCSELs in mechanically compliant formats without sacrifi cing their wafer-level performance is therefore critically important to realize the full potential of this technology for future applications in fl exible and wearable optoelectronics. In this Communication, we present approaches that can overcome aforementioned performance limitations of printed micro-VCSELs on fl exible substrates having low thermal conductivities by exploiting thermally engineered composite assemblies. Systematic studies on electrical, optical, and thermal properties of fl exible micro-VCSELs at various assembly confi gurations, together with thermal modeling based on 3D fi nite element analysis (FEA), highlight that the developed concept of materials design and device fabrication enables facile and effi cient heat removal from micro-VCSELs printed on plastics and therefore allows the realization of performance characteristics that are comparable to or even higher than those achievable on the source wafer, in ways that also preserve their critical benefi ts in mechanically fl exible and optically transparent constructions. Figure 1 a shows schematic illustration for printed arrays of micro-VCSELs in thermally engineered composite assemblies that heterogeneously incorporate materials of high thermal conductivity between the VCSEL and a polymeric substrate to facilitate an effi cient thermal management. Specifi cally, a thin (on the order of a few μm) layer of metal is introduced on the front surface of fl exible substrate, the bottom surface of the released micro-VCSEL, or on both, respectively, which we refer to as V-A-M-P, V-M-A-P, and V-M-A-M-P, respectively, where V, A, M, and P denote micro-VCSEL, organic adhesive, metal, and polymeric substrate, respectively. Figure 1 b shows schematic illustration and corresponding cross-sectional scanning electron microscope (SEM) images of the composite VCSEL assemblies on a polyethylene terephthalate (PET, ≈50 μm thickness), in which the thickness of adhesive and metal (Cr/Ag/Au: 10 nm/1000 nm/30 nm) layers is about ≈1.0 and ≈1.04 μm, respectively. Such advanced designs of fl exible composite assemblies for the effi cient thermal management of printed micro-VCSELs permitted dramatic improvement of output performance of devices operating on plastics while minimally affecting the mechanical fl exibility as well as the level of optical transparency in printed modules. Figure 1 c shows a photographic image of 5 × 5 arrays of interconnected microVCSELs integrated on a PET substrate mounted on a curved surface (bending radius: ≈12.0 mm), with comparable output characteristics to devices on the GaAs source wafer even under the fl exible and optically transparent format (Figures S1–S3, Supporting Information). This outcome was enabled by the Dramatically Enhanced Performance of Flexible MicroVCSELs via Thermally Engineered Heterogeneous Composite Assemblies

Challenges and opportunities in chemistry of graphene analogues

Graphene analogues can provide promising opportunities to satisfy peoples requirement of transparent portable nanodevices because of their ultrathin thickness, huge specific surface area and high flexibility. Expanding the study area of graphene analogues with a nonlayered structure or quasi-layered structure with relatively strong bonds between the layers will not only enrich the family of two dimensional crystals with atomic thickness, but also bring us unprecedented excellent properties and wide applications. However, because of the lack of long-range order in the third dimensionality, the characterization of these low-dimensional structures and the understanding of their clear structure-property relationship encounter many great difficulties. In this review, we focus on the recent advances in synthetic strategies for graphene analogues with the layered structure, nonlayered structure as well as the quasi-layered structure with relatively strong bonds between the layers. And we survey the recent progresses in fine structure and defects characterization of the ultrathin two dimensional crystals, and furthermore overview the methods for modulation of their electronic structures. In addition, the structure-property relationship, transparent and flexible device construction as well as wide applications in photoelectrochemical water splitting, photodetectors, thermoelectric conversion, touchless moisture sensing and supercapacitors of the graphene analogues were also highlighted. It is anticipated that the present review will deepen peoples understanding of this field and hence contribute to guide the future design of high-efficiency energy-related devices.

A Low-Complexity LDPC Coding Scheme for Channels With Phase Slips

We propose low-complexity coding schemes that are resilient against sporadic phase slip events. These schemes are based on a new phase-slip transparent construction of LDPC codes, called block symmetric codes and on outer differential coding. The slip transparent LDPC codes correct single bit error events but are transparent to phase slips. The phase slips, which correspond to runs of bit errors, are corrected by the outer coding part of the receiver. We present practical binary and nonbinary code constructions for multiple modulation formats, and evaluate the proposed scheme by means of simulation examples.

On the development of Korean SAY evidentials and their extended pragmatic functions

This paper examines the development of five hearsay evidential markers in Korean, namely, tako, tamye, tamyense, tanun and tanta, and traces their extended pragmatic functions in discourse. We first identify their functions over time, from Middle Korean to Modern and Contemporary Korean, then quantitatively analyze the usage frequency of these functions, diachronically from the 16th century to the early 20th century using the UNICONC historical corpus, and synchronically in present-day Korean using the Sejong contemporary written and spoken corpus. From a pragmatic perspective, we examine how Korean speakers use these hearsay evidential markers to convey the interpersonal and intersubjective stances of interlocutors in natural conversations. Based on the differential rates of grammaticalization of these markers, and on their usage frequency, we also examine the relationship between evidentiality marking and finiteness; more specifically, we analyze the sequences and mechanisms of change whereby different types of non-finite evidential structures develop into finite evidential constructions. Our findings have broader theoretical and crosslinguistic implications for understanding the mechanisms of insubordination, whereby dependent structures become independent, and whereby lexically transparent constructions develop into grammaticalized markers of speakers’ stance.

An ERP study on L2 syntax processing: When do learners fail?

Event-related brain potentials (ERPs) can reveal online processing differences between native speakers and second language (L2) learners during language comprehension. Using the P600 as a measure of native-likeness, we investigated processing of grammatical gender agreement in highly proficient immersed Romance L2 learners of Dutch. We demonstrate that these late learners consistently fail to show native-like sensitivity to gender violations. This appears to be due to a combination of differences from the gender marking in their L1 and the relatively opaque Dutch gender system. We find that L2 use predicts the effect magnitude of non-finite verb violations, a relatively regular and transparent construction, but not that of gender agreement violations. There were no effects of age of acquisition, length of residence, proficiency or offline gender knowledge. Additionally, a within-subject comparison of stimulus modalities (written vs. auditory) shows that immersed learners may show some of the effects only in the auditory modality; in non-finite verb violations, an early native-like N400 was only present for auditory stimuli. However, modality failed to influence the response to gender. Taken together, the results confirm the persistent problems of Romance learners of Dutch with online gender processing and show that they cannot be overcome by reducing task demands related to the modality of stimulus presentation.

Facebook as a third author—(Semi-)automated participation framework in Social Network Sites

Questioning the transparent construction of emerging Web 2.0 discourse communities, this article asks in what ways structural options and restrictions of the software service ‘Facebook’ offer new semiotic resources and set up (novel) conditions for participation. More specifically, it holds that the medium in use and the particular software service acts as a kind of third author: The electronic environment and its functional properties facilitate and delimit a variety of discourse patterns and thus intervene in the communication between profile owner and profile recipients.To assess the impact of the electronic environment on user participation within Facebook, the present article will first introduce the notion of (technological) affordances and discuss characteristic ‘action possibilities’ that are typically offered by Social Network Sites. It will then give background information on general features of participation in online environments and identify key functions of the Facebook environment. On the basis of these findings, the article will discuss how Facebook's communicative properties enable and constrain textual practices and social interaction (functional affordances). Data from actual Facebook members give weight to how individuals adapt in different ways to software-biased action possibilities (relational affordances).

Glass landslide: the 3D visualization makes study of landslide transparent and virtualized

As the global research topic, geological disasters have led to huge losses around the world yearly. In this paper, three-dimensional (3D) visualization is used as a technical method to build the 3D geological model of the HuangTuPo (HTP) landslide, and the 3D model of large field test base located in the HTP landslide, and the 3D regional geological model. These models make the landslide research digitized and transparent. Meanwhile, the preliminary studies were carried out: the comprehensive utilization of multiple scales and multiple categories of data—by “Double Center”, and the 3D data integration from region to point of disasters—by the component technology, and the transparent design and construction of disaster research—by 3D model shearing. Through these methods, the surface topography and the underground geological structure of landslide can be displayed as transparent as glass, and the virtual simulation on the results of underground engineering can be carried out in advance, providing guidance for engineering design and construction.

A characterization of equilibrium set of persuasion games with binary actions

This paper considers a persuasion game between one sender and one receiver. The perfectly informed sender can fully certify any private information that is drawn from a continuum set, and the receiver has binary actions. We focus on the situation where both full information disclosure and full information suppression are impossible. We characterize the set of pure strategy equilibria in terms of informativeness measured by the receiver’s ex ante expected utility in this environment; there exist continuum equilibria. The set is characterized by the most and the least informative equilibria, and then any value between the bounds can be supported in equilibrium with transparent construction of the associated equilibrium.
