description: According to the Canadian Urban Transit Association (CUTA 2012), 140 Billion CAD is required to maintain, rehabilitate, and replace subway infrastructure between the years 2010 and 2014. However, transit authorities are faced by a fund scarcity problem which is hindering them from addressing all the network rehabilitation requirements in an efficient manner. The solution according to the 2013 America’s infrastructure report card is to adopt a comprehensive asset management system to maximize investments. This research develops a risk assessment model for subway stations. Probability of failure of different subway elements are developed using Weibull reliability curves. Consequences of failure are measured against three predefined attributes these are financial, operational, and social impacts of failure. Finally, a criticality index measures the respective station criticality derived from its particular size, location in proximity to different attraction types, and, nature of use. A qualitative approach with the help of expert judgment is adopted to integrate the indices using the Fuzzy Analytic Network Process with application to Fuzzy Preference Programming. The three models are integrated into a fuzzy rule based risk index model to compute element and station expected risk index. The output of the model is a comprehensive risk index that can be used to prioritize elements across stations for rehabilitation. The model is verified through an actual case study comparing elements across six stations and computing probability of failure, consequence of failure, criticality and the risk index. This paper illustrates the general framework of the proposed methodology which will help decision makers prioritize stations and elements across stations for rehabilitation based upon their risk index.

description: This text is about Victor Bor, Tio Jorge and Ntombikte Na Natchi, who in the mid-1980s felt the inner earthquake of Kyangyang, the “Shadow” in Balanta Kuntohe. This phenomenon took place during the period when Nino Vieira was president of the Republic of Guinea-Bissau, between 1980 and 1998, and when Dutch psychiatrist Joop de Jong ran the psychiatric hospital in Bissau. The Kyangyang went down in history as a post-colonial messianic movement that caused enormous turbulence within the Balanta community of this small West African territory. In general, both the people who were part of the movement and those around them describe it as being made up of people who had been caught up in the Shadow, i.e. who suddenly and synchronously saw and heard the dead reveal to them the secrets of writing and healing. Victor Bor describes visions of lights and explosions that are sometimes confused with episodes from the liberation war that took place a decade ago, but also with the civil war that at the end of the 1990s destroyed the psychiatric hospital designed by Joop de Jong. Tio Jorge, the brother of the woman who became the prophetess of Kyangyang in the 1980s, said in a conversation we had in Bedanda in 2019, in southern Guinea-Bissau, that it all started with a small earthquake.

description: Considering the scarcity of information and the lack of knowledge regarding stenography –very rarely used or called upon nowadays, both in daily and academic contexts – and given the decreasing number of people who hold this specific knowledge, it becomes increasingly urgent the creation of a relevant archaeological and bibliographic Iberian archive of this almost extinct writing form.

This text arose in the context of a master’s degree aiming to study the universe of stenography and its relevance (if any) in contemporary contexts and technologies. To accomplish this, it was crucial to have access to reliable information regarding this writing form. This objective was pursued through a non-interventionist qualitative methodology that included methods such as bibliographic research, literature review and critique, interviews with experts in the field (namely stenographers, teachers, students) and in-depth case studies.

In this paper, we present the groundwork that enabled us to gather information about Portuguese shorthand which was of crucial importance to the development of the project. The bibliographic research revealed the existence of several Portuguese shorthand authors. Through in-depth research and a comparative study among various case studies, we observed that each shorthand system exhibited peculiarities, setting it apart from the others. This divergence was attributed to individual authors' endeavors to revolutionize the field of Portuguese shorthand, striving to establish their methods as the fastest and most effective. Noteworthy distinctions surfaced in areas such as the representation of the stenographic alphabet, the portrayal of numerals in text, the handling of articles, names, abbreviations, and suppressions, among other aspects. None of them provided evidence to determine the official Portuguese shorthand system. However, the interviews conducted revealed that the Martinian System was the official one. They also helped us gain insight into the teaching methods of shorthand employed in class, as well as the layouts students used to enhance writing efficiency.

description: We examined the output of a quantum Michelson interferometer incorporating the combined effects of nonlinear optomechanical interaction and time-varying gravitational fields. Our findings indicate a deviation from the standard relationship between the phase shift of the interferometer's output and the amplitude of gravitational waves. This deviation, a slight offset in direct proportionality, is associated with the gravitational wave memory effect under the conventional settings of interferometer parameters. Furthermore, the results suggest that consecutive gravitational wave memory, or the stochastic gravitational wave memory background (SGWMB), contributes not only to the classical red noise spectrum but also to a quantum red noise spectrum through this new mechanism. This leads to a novel quantum noise limit for interferometers, which may be crucial for higher precision detection system. Our analysis potentially offers a more accurate description of quantum interferometers responding to gravitational waves and applies to other scenarios involving time-varying gravitational fields. It also provides insights and experimental approaches for exploring how to unify the quantum effects of macroscopic objects and gravitation.
The Written Word in the Design of Learning Spaces: Workshop A Rede

description: This article presents and reflects on the work developed in the Workshop A Rede of the Picnic educational project, part of the 7th Other Delli Week, an event for students of the communication design degree programme at DELLI - Design Lusófona Lisboa. This project proposed exploring the learning space as an informal and communitarian environment, transporting the school out of doors through the structure of a picnic. The workshop dealt with the design of natural space through the concepts of appropriation, protection, relationship and communication, in the relationship between the suspended fabric, the written word and poetry. The team explored the word (its construction, rhythm and meaning), typography (experimental work on letter design) and their relationship with support, material, and space, to create a poetic structure with six suspended fabrics. The article is divided into four sections: a brief overview of the Picnic educational project; a theoretical framework; a description of the activities; and finally, a reflection on the work process and results. The text is guided by visual references that frame the project and photographs collected during its preparation and final installation. This article was developed especially for the Typography Meeting 13 – Other Typographic Worlds, framed in the topics Art, Language and Typography, Text as Image and Image as Text, and Pedagogy and Methods in the Teaching of Type Design.

description: We compute the N-jettiness soft function in hadronic collisions to next-to-next-to-leading order (NNLO) in the strong-coupling expansion. Our calculation is based on an extension of the SoftSERVE framework to soft functions that involve an arbitrary number of lightlike Wilson lines. We present numerical results for 1-jettiness and 2-jettiness, and illustrate that our formalism carries over to a generic number of jets by calculating a few benchmark points for 3-jettiness. We also perform a detailed analytic study of the asymptotic behaviour of the soft-function coefficients at the edges of phase space, when one of the jets becomes collinear to another jet or beam direction, and comment on previous calculations of the N-jettiness soft function.

Nancy Cunard and The Hours Press. Parallax – A Skewered Angle on the History of Publishing
Creators: name: Thon Knutsen, Ane
Publisher: name: International Journal of Film and Media Arts
Year: 2024

description: This study aims to explore the artistic and cultural contributions of Nancy Cunard, a printer, publisher, and designer from the inter-war modernist era, with a focus on her work as a letterpress printer and her connection to Virginia Woolf. The research investigates how Cunard’s printing practice was influenced by Woolf’s pioneering efforts in setting up The Hogarth Press in 1917 and how Cunard, like Woolf, challenged established hierarchies and norms within the publishing industry, setting up her own The Hours Press in 1927.
The study also delves into the collaborative relationship between Woolf and Cunard, particularly in relation to the publication of Cunard’s poem Parallax, which Woolf typeset and published. It highlights the shared themes of their works, addressing the aftermath of World War I and the Spanish Flu, and challenges the notion that Cunard’s poem was merely a pale imitation of T.S. Eliot’s The Waste Land. The research sheds light on the misogynistic devaluation of women’s contributions within the publishing industry.

Cunard’s memoirs, entitled These Were the Hours, serve as a comprehensive account of her involvement in printing and publishing. She sought to create aesthetically pleasing books while disregarding conventions, embracing experimentation, and following her own aesthetic instincts. Cunard’s printing practice reflected a punk-ish aesthetic, featuring rough bindings, expressive covers, and typographical and visual playfulness.

In conclusion, this study aims to bring recognition to Nancy Cunard’s often-overlooked artistic contributions and shed light on the historical significance of her printing practice. By examining Cunard’s work through the lens of graphic design and letterpress printing, the research contributes to a broader understanding of self-publishing history and its impact on contemporary artist books. The study highlights the parallel struggles faced by Woolf and Cunard within a patriarchal system and underscores the enduring relevance of their unconventional approaches to printing and publishing.

Typographic Design as Visual Historiography and Racial Formation
Creators: name: Lee, Chris
Publisher: name: International Journal of Film and Media Arts
Year: 2024

description: This paper maps the theoretical and methodological dimensions of an on-going project called 1882–1982–2019 which entails the design of a “chop suey” typeface and specimen book. The project experiments with typography’s indexical affordances and capacity for historical narration. The typeface is not optimized for legibility, but is rather developed for unpacking critical questions surrounding the relationship between labor, design, craft, quality, value, and race. While most of these notions would not be out of place in discourses of typography, the latter term — race — is seldom given serious attention in the field.

The typographic (or, type) specimen is taken up as a genre of commercial writing that invests letterforms with significance and value. It is framed by a synthesis of scholarly work from a variety of fields including performance studies, whiteness studies, and Asian-American studies, and the history of illustration. This idiosyncratic composition of reference points strives towards a more radical resonance. That is, 1882–1982–2019 is rooted in an examination of the historical persistence of the anti-Asian tropes as one constitutive element in the construction of normative, white-supremacist ideas around labor, craft, and value. It explores how the language and attitudes of such tropes are resonant in typographic discourse, pedagogy, and practice.

A primary methodological vehicle — endemic to type design — entails the mining of archival sources for letterforms. These are extracted from a variety of historical documents ranging from late-19th century political cartoons to contemporary popular media, and digitized. Artificial intelligence image generators like Dall-E and Midjourney are also applied to generate typographic form to stage a further examination of the performativity of contemporary typographic labor.
This project opens critical questions about the disciplinary aims of typographic history, implicates it in racial discourses, and challenges normative, ostensibly de-racialized, processes of valorization in typography.

Condition diagnostics of steel water tanks using correlated visual patterns

Year: 2015

description: Insufficient, unreliable, and delayed condition assessment of steel water tanks is causing poor maintenance planning, wastes of maintenance resources, and unexpected structure failures. Visual inspection of water tanks heavily relies on engineers’ experiences for achieving comprehensive and reliable condition assessments. Recent studies reveal the potential of using imaging technology for improving the efficiency and comprehensiveness of capturing visual conditions of large civil infrastructures, but manual interpretation of imagery data still impedes engineers from reliable awareness of structural conditions. On the other hand, some studies show that deteriorations of structures result in correlated visual patterns that can assist engineers in structural diagnosis. The objective of the research presented in this paper is to examine correlated deformation patterns of a steel tank based on analyzing 3D laser-scanned point clouds collected in the field. Specifically, the authors aim at identifying correlated shape change patterns of a water tank through various 3D data analysis algorithms, and synthesize these 3D data patterns as knowledge for guiding data-driven condition assessment of the water tank. The authors examined two 3D data analysis approaches for revealing the deformation patterns of the studied tank. The first approach calculates the deviations of the 3D data points from as-designed shapes of the water tank for identifying structural deformation and defects. The second approach visualized anomalous variations in local shape descriptors, such as curvature, for identifying defects of structures. Correlations between the patterns could then reveal systematic changes of the tank for helping engineers conduct more reliable condition assessments.

description: From the funky, fresh Black modernism of the Johnson Publishing Company’s headquarters designed by John Warren Moutoussamy with Arthur Elrod and William Raiser to the expressive graffitied grids of Adam Pedelton’s monumental canvases in black and white, there lives a wide-ranging matrix of possibilities for what I consider to be a Black Grid. As a queer Black artist, designer, and design historian, living and working in conditions of a triple consciousness of overlapping marginalization, I have been in countless situations throughout my career, surrounded by a sea of practices and pedagogies that don’t represent me, my lived experience, or that of kindred spirits. As a result, I have committed to redirecting and centering art and design BIPOC (Black Indigenous People of Color) voices and scholarship in making, writing, and education as a transformational process. To that end, I enact poetic research, which seeks to find lineages from biological ancestors, antecedents in art and design, and chosen family.

description: Homo- and heterodyne detection are fundamental techniques for measuring propagating electromagnetic fields. However, applying these techniques to stationary fields confined in cavities poses a challenge. As a way to overcome this challenge, we propose to use repeated indirect measurements of a two-level system interacting with the cavity. We demonstrate numerically that the proposed measurement scheme faithfully reproduces measurement statistics of homo- or heterodyne detection at the single-shot level. The scheme can be implemented in various physical architectures, including circuit quantum electrodynamics. Our results pave the way to the implementation of quantum algorithms requiring linear detection, including quantum verification protocols, in stationary modes.

description: We obtain necessary and sufficient conditions on weights for a wide class of integral transforms to be bounded between weighted $L^p-L^q$ spaces, with $1\leq p\leq q\leq \infty$. The kernels $K(x,y)$ of such transforms are only assumed to satisfy upper bounds given by products of two functions, one in each variable.
 The obtained results are applicable to a number of transforms, some of which are included here as particular examples. Some of the new results derived here are the characterization of weights for the boundedness of the $\mathscr{H}_α$ (or Struve) transform in the case $α>\frac{1}{2}$, or the characterization of power weights for which the Laplace transform is bounded in the limiting cases $p=1$ or $q=\infty$.

description: Selective attention prioritises relevant information amongst competing sensory input. Time-resolved electrophysiological studies have shown stronger representation of attended compared to unattended stimuli, which has been interpreted as an effect of attention on information coding. However, because attention is often manipulated by making only the attended stimulus a target to be remembered and/or responded to, many reported attention effects have been confounded with target-related processes such as visual short-term memory or decision-making. In addition, attention effects could be influenced by temporal expectation about when something is likely to happen. The aim of this study was to investigate the dynamic effect of attention on visual processing using multivariate pattern analysis of electroencephalography (EEG) data, while (1) controlling for target-related confounds, and (2) directly investigating the influence of temporal expectation. Participants viewed rapid sequences of overlaid oriented grating pairs while detecting a "target" grating of a particular orientation. We manipulated attention, one grating was attended and the other ignored (cued by colour), and temporal expectation, with stimulus onset timing either predictable or not. We controlled for target-related processing confounds by only analysing non-target trials. Both attended and ignored gratings were initially coded equally in the pattern of responses across EEG sensors. An effect of attention, with preferential coding of the attended stimulus, emerged approximately 230 ms after stimulus onset. This attention effect occurred even when controlling for target-related processing confounds, and regardless of stimulus onset expectation. These results provide insight into the effect of feature-based attention on the dynamic processing of competing visual information.

description: Abstract: There is a widespread belief that in the 1970s, two conflicting theories of the adhesion of a spherical particle to a substrate were published: the JKR and DMT theories. And that the dispute was resolved when Tabor introduced a parameter μ, such that for small μ, DMT was correct, while for large μ, JKR was correct. We point out that there never were two theories of contact: the dispute was about the magnitude of the pull-off force (with an implication that since the DMT value was obtained by a thermodynamic method, it must be correct). And what Tabor actually said was simply that for large μ, the neglect of surface forces in the JKR theory was acceptable, and that he distrusted the neglect of deformation by the large surface forces immediately outside the Hertzian contact in the DMT theory. We point out the errors in both the DMT/MDT thermodynamic method and the MDT force method (preferred by MDT) but also argue that once Derjaguin and his collaborators (MYD) established that Hertzian geometry does not occur, no theory based on that geometry should be taken seriously. Derjaguin’s well-merited fame rests on more important contributions.

description: Die Abschlusspräsentation am 27. März 2024 in Bangkok im Rahmen des internationalen Projekts "The Societal Welfare Gains of Stainless Steel Recycling in Thailand" fasst die Ergebnisse der Studie zusammen und zeigt auf, wie Edelstahlrecycling Thailand wirtschaftliche und ökologische Vorteile bringt. Dabei wird die Betroffenheit Thailands durch den fortschreitenden Klimawandel eingeordnet und der Wert der Emissionseinsparungen beziffert. Jede Tonne Edelstahlrecycling spart - im Vergleich zur Verwendung von Primärrohstoffen - bis zu 6,71 Tonnen CO₂ und generiert einen gesellschaftlichen Nutzen, der mit einem "Scrap Bonus" von 14.000 bis 48.000 Baht pro Tonne bewertet wird. Der "Scrap Bonus" monetarisiert und reflektiert den sozialen und ökologischen Nutzen des Edelstahlrecyclings und ermöglicht der breiten Öffentlichkeit ein besseres Verständnis der Emissionseinsparungen, umgerechnet in die Landeswährung. Darüber hinaus empfiehlt die Studie eine stärkere CO₂-Bepreisung, die Integration des Recyclings in das Bio-Circular-Green-Modell sowie Maßnahmen zur Förderung von Handel, Forschung und Bildung. Abschließend wird betont, dass Thailand mit diesen Ansätzen eine führende Rolle in der Kreislaufwirtschaft einnehmen und damit die globalen Klimaziele aktiv unterstützen kann.

 Such functions form a family of quantized collision invariants which play a fundamental role in the study of hydrodynamic regimes of the Boltzmann--Fermi--Dirac equation near Fermionic condensates, i.e., at low temperatures. In particular, they characterize the elastic collisional dynamics of Fermions near a statistical equilibrium where quantum effects are predominant.
Automated monitoring of hardhats wearing for onsite safety enhancement

description: Construction is one of the most dangerous job sectors over the world. Any accidents that happen on the construction sites will bring the sufferings to the workers and their families and incur the delays and costs to the projects. Therefore, it is necessary for the contractors to monitor potential site safety issued and comply with existing safety regulations all the time. One of fundamental safety regulations is hardhat wearing. The wearing of the hardhats is always mandated and should not be violated anytime on the construction sites. In this paper, a novel method is proposed to facilitate the monitoring of whether any persons on the construction sites are wearing hardhats as required by the safety regulations. The method is built upon computer vision techniques. Under the method, human bodies and hardhats are first detected in the video frames captured by real-time on-site construction cameras. Then, their pair-wise matching is found. For those persons without the matching of the hardhats, they are identified as not wearing hardhats. The proposed method has been tested on real site videos. The test results showed that multiple persons could be monitored even if they are not wearing any real-time location sensors or tags. The test results demonstrate the potential of using live streaming or time-lapse construction site videos to facilitate the safety monitoring work on construction sites.

description: In this second part of our two-series on extracting the Hawking temperature of dynamical black holes, we focus into spacetimes that are conformal transformations of static spacetimes. Our previous investigation builds upon the Unruh-Hawking analogy, which relates the spacetime of a uniformly accelerating observer to the near-horizon region of a black hole, to obtain the Hawking temperature. However, in this work, we explicitly compute the Bogoliubov coefficients associated with incoming and outgoing modes, which not only yields the temperature but also thermal spectrum of particles emitted by a black hole. For illustration, we take the simplest nontrivial example of the linear Vaidya spacetime, which is conformal to the static metric and using this property, we analytically solve the massless scalar field in its background. This allows the explicit computations of the Bogoliubov coefficients to study the particle production in this spacetime. We also derive an expression for the total mass of such dynamical spacetimes using the conformal Killing vector. We then perform differential variations of the mass formula to determine whether the laws of dynamical black hole mechanics correspond to the laws of thermodynamics.

description: At the heart of this project is a strong interest in a Digital Humanities service provided by the Estense Library of Modena. The institution has not only made a significant portion of its documentary heritage available in open access through the MLOL portal (Estense Digital Library) but has also enhanced its value by adopting an innovative technology known as IIIF (International Image Interoperability Framework). This system enables the visualization, search, annotation, sharing, and manipulation of ultra-high-definition images.

One particularly valuable feature of the platform is the "stories" tool, a digital storytelling function based on the IIIF standard, which allows users to create narrative journeys using the available digital resources. This service played a key role in the development of this project: leveraging the digitization of manuscript α.L.05.15 (the so-called Marcanova Codex), a digital narrative was created. The data collected from the epigraphic transcriptions in the urban section of the work were transformed into metadata and carefully linked to selected images from the manuscript.

description: In this paper we systematically consider various ways of generating integrable and separable Hamiltonian systems in canonical and in non-canonical representations from algebraic curves on the plane. In particular, we consider Stäckel transform between two pairs of Stäckel systems, generated by 2n-parameter algebraic curves on the plane, as well as Miura maps between Stäckel systems generated by (n+N)-parameter algebraic curves, leading to multi-Hamiltonian representation of these systems.

description: In this article, some elementary observations are made regarding the behavior of solutions to the two-dimensional curl-free Burgers equation which suggest the distinguished role played by the scalar divergence field in determining the dynamics of the solution. These observations inspire a new divergence-based regularity condition for the two-dimensional Kuramoto-Sivashinsky equation (KSE) that provides conceptual clarity to the nature of the potential blow-up mechanism for this system. The relation of this regularity criterion to the Ladyzhenskaya-Prodi-Serrin-type criterion for the KSE is also established, thus providing the basis for the development of an alternative framework of regularity criterion for this equation based solely on the low-mode behavior of its solutions. The article concludes by applying these ideas to identify a conceptually simple modification of KSE that yields globally regular solutions, as well as providing a straightforward verification of this regularity criterion to establish global regularity of solutions to the 2D Burgers-Sivashinsky equation. The proofs are direct, elementary, and concise.

description: Differential equations of the form $\ddot R=-kR^γ$, with a positive constant $k$ and real parameter $γ$, are fundamental in describing phenomena such as the spherical gravitational collapse ($γ=-2$), the implosion of cavitation bubbles ($γ=-4$) and the orbital decay in binary black holes ($γ=-7$). While explicit elemental solutions exist for select integer values of $γ$, more comprehensive solutions encompassing larger subsets of $γ$ have been independently developed in hydrostatics (see Lane-Emden equation) and hydrodynamics (see Rayleigh-Plesset equation). I here present a universal explicit solution for all real $γ$, invoking the beta distribution. Although standard numerical ODE solvers can readily evaluate more general second order differential equations, this explicit solution reveals a hidden connection between collapse motions and probability theory that enables further analytical manipulations, it conceptually unifies distinct fields, and it offers insights into symmetry properties, thereby enhancing our understanding of these pervasive differential equations.

description: Digital models incorporating 3D geometry and information attributes are becoming a standard for industrial facility and commercial building design. Despite the advancements in technologies to develop design models there is an opportunity to better leverage models within facility construction processes. The current work aims to identify the breadth of construction needs for using information models, and develop an approach to improve information accessibility to support construction. With a thorough literature review, the current work identifies the state-of-art workflows in using design content to support construction tasks. The existing gaps of using models for construction uses have also been captured, indicating the opportunities of better leveraging model content throughout construction process. Discussion of how a planning approach and implementation guidelines will be developed to advance model uses in construction will help conclude the paper.

An ontology-supported transaction formalism protocol in infrastructure management

description: Infrastructure organizations use diversified information systems to exchange data (transaction). Presently, data exchange in the area of infrastructure management is accomplished in a manual and ad hoc basis. The growing trend is to transform these manual data exchanges to a computer-to-computer based exchange of information. “How to formalize these data exchanges or transactions?” is the core research question, which was dealt with developing and applying an ontology-supported Transaction Formalism Protocol (TFP). The proposed solution is composed of two parts: ontology and protocol. Two ontologies, the Transaction Domain Ontology and Tangible Capital Asset ontology, were developed using an eleven-step methodology to represent transaction knowledge and Tangible Capital Asset knowledge respectively to support the design and implementation of transactions in infrastructure management. The proposed TFP is an eight-step procedure developed using a four-step methodology from two perspectives: the TFP Specification modelled each step of the protocol as a function for which inputs, controls, mechanisms, tools/techniques, and outputs were defined, whereas the TFP Tool includes a set of forms and guidance developed for specific steps of the protocol. The TFP was applied to develop transaction specifications for the Asset Inventory and Condition Assessment Reporting/Tangible Capital Asset (AI&CAR/TCA) Reporting, which was implemented in the Asset Information Integrator System for the exchange of Tangible Capital Asset information between the municipal and provincial governments. The main contributions of this research work include the development of the two ontologies, protocol, and Asset Integrator Information System.
