Full textAbstract:
This article seeks to explore the use of multiple semiotic resources in a multimodal text, namely a YouTube video on the Hans Brinker Budget Hotel in Amsterdam. More specifically, it observes how dynamic intersemiosis is adopted for humorous meaning-making and with an ultimate promotional function. First, it is here claimed that dynamic intersemiosis acts as the humour-enacting trigger enabling script shift, i.e. the semantic process of frame reversal inherent in humour generation. Then, multimodally expressed humour is discussed as performing a parody of similar tourism and eco-tourism texts and of the specialized language they adopt. The questions raised are: How do dynamic images and the soundscape combine in terms of congruence and dissonance? How does intersemiosis act as a humour-enacting trigger in the multimodal artefact? How does multimodally expressed humour position the Hans Brinker Hotel within a tourism discourse? How and why is the parody of promotional (eco)-tourism videos realized?

Full textAbstract:
Kaleidographic is a dynamic and interactive data visualization tool that allows users to observe and explore relations between any number of variables. It was developed in reaction to the problem of capturing the complex ways in which words and images combine to make meaning. This article introduces the Kaleidographic tool through a case study examining the multimodal construction of news values in news items widely shared on the Facebook social media platform. The design and functionality of the tool are explained in relation to the challenges faced when exploring both the visual and verbal elements of these news items as part of a multimodal discourse analysis. Through this case study, the authors show that Kaleidographic offers multimodal researchers a means of exploring relations at the intersection of different semiotic modes that might be missed in static graphs and tables. Despite Kaleidographic being initially conceived out of the analysis of text–image relations, the case study demonstrates that it has potential applications beyond multimodal discourse analysis. To facilitate broader applications of the tool, it is now publicly available online for use without charge.

Full textAbstract:
Based on a larger practice-based research project in digital writing, this article examines how the materiality of digital media contributes to a layered metaphor that delivers meaning, reflects on the cognitive processes (the writer’s and the reader’s) of navigation and generates a dynamic narrative structure through multimodality, unnatural narration and user interaction. Many writers and artists engage with their chosen medium through an instinctive understanding of the materials at hand, gained through experience; the explicit study of a medium’s materiality is not always required for artistic success, however, that may be judged. This article offers insights into the creative process of creating digital, multimodal fiction, based on a practice-based research project designed to explore the effects of digital media on author and text, and argues that digital media have a significant effect on the outcome of the artefact itself. Awareness of these effects, their variations according to hardware and software, and the affordances of these various materials offer the digital writer greater insight and capability to craft his/her texts for the desired metaphorical meaning.

Full textAbstract:
This article contributes to the multimodal investigation of comics translation, a highly semiotic activity. The author discusses the visual representation of the text as an image through a case study of the Lithuanian translation of Art Spiegelman’s graphic novel MAUS (translated into Lithuanian by Juškienė and Lempert, 2012). While viewing multimodality as a translation tool and a challenging area, he claims that the visual representation of the text is an integral part of the original multimodal event, whereby the meaning is conveyed through an intrinsic relationship between verbal and non-verbal elements, and that any distortion of those would result in alterations or losses in meaning. The results demonstrated that indeed even the smallest alterations of the visual representation of the text produced shifts in meaning; most of those shifts were pragmatic ambiguities, however, in certain instances there was a loss of semantic emphasis or narrative production. Comics translators and publishers are thus urged to fully comprehend the very dynamic and complex nature of multimodal texts and make every effort to ensure that translation would not result in any multimodal disruptions, if such preservation is technologically available.

Full textAbstract:
Homogeneous texts are being replaced by heterogeneous texts that are called audio-visual ones; texts and teletexts belong to the most formed of them. On the ground of cinema and television the texts with the unique structure that combines verbal and non-verbal sense carriers apoeared. The aim of this work is to describe peculiarities of meaning articulation in the dynamic scope of such screen texts. To reach the aim the task to show how the basic elements of the screen “language” materialize in verbal and non-verbal units of the screen “speech” of polycode-multimodal text and how it constructs the general meaning of audio-visual narration is set. Also contamination of levels of meaning is being studied in this work and how it influences the trope. The research is being held on the case of the film text “Faust” by A. Sokurov. The analysis is being done on the space-time continuum, i.e. with the consideration of the movement in the film text. Units of the screen “speech” are being extracted from the chosen segments and analysed as the main sources of the meaning of audio-visual message as a whole; also the peculiarities of the meaning articulation on the denotational and connotational levels in space-time scope of polycode-multimodal text are being described. Apart from that, the process of semiotic interpolation of verbal and non-verbal units that leads to the generating of the transitional meaning and of the trope on the grounds of displacement and adjacency of the meanings is being studied. The author comes to the conclusion that integrity of verbal and non-verbal units in the space-time scope of the polycode-multimodal text, that results in trope generation, also leads to the semiotic situation of simulacrativity, whose main goal is to make the spectator believe that what is happening on the screen is real. This article is aimed at students, post-graduates, professors, linguists and others interested in general and linguistic semiotics.

Full textAbstract:
Abstract The current study investigates classroom interactivity in L2 tertiary literature classrooms in Hong Kong and Taiwan when ESL/EFL students engage with and interpret literary texts in classroom talk as a pedagogic process of text recontextualization. It proposes a more ecological-based approach to language and languaging dynamics that is complementary to current social semiotic approaches to multimodality. It also aims to open up a more embodied analysis of the meaning-making process in tertiary literature classrooms. The multimodal investigation of real-time classroom interactivity based on a multi-scalar approach showcases an embodied coordination of vocalization and gesticulation as integral aspects of the dynamic whole-body sense-making activity that arises in the pedagogic process of text recontextualization. The dynamics vary from students’ solo speech in individual presentation to teacher–student interactions in group discussion and to student–student interactions in role-play. The distributed language view of first-order languaging dynamics demonstrates the embodied and distributed dimensions of the real-time classroom interactivity that couples pedagogic subjects to the affordances of their pedagogic environment. It also provides insights into the impact of pedagogic activities on the multi-scalar dynamics of the meaning-making process with reference to embodied speech–gesture coordination. The paper demonstrates the value of applying an ecologically embodied perspective to multimodal studies in classroom research and stimulates a re-thinking of some of the important aspects of classroom interactivity that have received little attention thus far.

Full textAbstract:
This paper considers the merit of manga versions of Shakespeare's Hamlet and Cervantes' Don Quijote de la Mancha which employ the impressionistic techniques of the Japanese comic format to create new, dynamic texts. Such multimodal texts demand different verbal and visual skills to decode the synergy between word and image and elements like the page layout, the size and shape of images and speech balloons and the style of lettering. Far from debasing the cultural authority of the originals by blurring the boundaries between high and popular culture, these versions can be seen as an act of salvage of the original texts from the perceived difficulties of challenging language and content, reinvigorating them with a vibrant immediacy. By making demands on the imagination and intellect in exciting ways, they may also salvage the act of reading itself by encouraging a young or reluctant readership, as well as the already enthusiastic, to explore new ways of engaging with a text.

Full textAbstract:
Abstract Kaleidographic is a dynamic and interactive data visualization tool that allows users to observe and explore relations between any number of variables. The tool is useful for displaying the complex ways in which textual elements interact across a range of texts. Thus far, the tool has been used to display the results of corpus studies as well as corpus-assisted multimodal discourse analyses that investigate text-image relations. To facilitate broader applications of the tool, it is now publicly available online for use without charge. This paper explains the background and motivation for Kaleidographic and presents two case studies demonstrating its utility. Limitations of the tool are discussed and its potential uses in corpus linguistics research and beyond are introduced.

AbstractThe aim of the present paper is to contribute to a better understanding of the role of heraldry, in particular of para-heraldic devices known as “badges”, in 15th-century England. The case chosen for examination is that of the white rose, one of the major badges of Edward IV.The data consists of four contemporary texts in which Edward is referred to as the “rose”, analysed against the background of the use of the white rose of York as a heraldic device. This includes surviving artefacts ranging from effigies to stained glass to seals and manuscript illuminations, as well as contemporary descriptions and depictions of those artefacts.Using the methodological apparatus of cognitive linguistics, specifically the multimodal metaphor and metonymy analysis, the author examines the interplay between language and heraldry. The results show that while the primary function of the white rose and of other badges employed by Edward IV was to emphasize his heritage and thus invite a metonymic reading, the badge inspired other, metaphorical readings, which were employed rhetorically by his supporters. In this context, the concept of the badge may be reinterpreted as a metaphtonymy.The analysis supports the view of heraldry as an integral element of medieval society. From a semiotic perspective, heraldry should be seen as a dynamic system that could be exploited creatively to suit the needs of its users, which in turn corresponds to the dynamic theory of metaphor.

Full textAbstract:
Multimodal studies motivated by Systemic Functional Linguistics have grown in interest and reach in the millennium, with contributions at the theoretical and methodological level extending across an increasing array of semiotic modes. This thesis drew on developments in tools for multimodal analysis applied across ‘multi’ modes in the broad field of advertising. Specifically, the advertising in the study refers to university brand marketing, more specifically the brand marketing products of posters and short films published by the three public universities in South Australia, The University of Adelaide (UofA) Flinders University (Flinders) and The University of South Australia (UniSA). The primary tools for analysis were Baldry and Thibault’s (2006) Multimodal Transcription and Text Analysis, and O’Halloran and colleagues’ (2013) Multimodal Analysis for Critical Thinking software package. These analytic tools were supplemented by developments in the study of other modes of meanings, including the work of Van Leeuwen (2011) on colour and Machin (2010) on music. The study also used the notion of intermodality, to consider how different modes work together in complementary ways to enhance the meaning making potential available to them separately. A detailed description, analysis and interpretation of the contribution of each semiotic mode used in the posters and films was undertaken, namely of the written language, spoken language, static images, moving images, static typography, kinetic typography, sound and colour, including how they were integrated intermodally. The study aimed to understand how the meanings in the posters and films were created from a multimodal perspective. It highlighted the vast range of meaning making resources at the disposal of the producers of these artefacts, and how the potential was actually realised in a small number of motifs which could be linked to each institution and its identity. The films had more resources to work with and with the use of these additional semiotic modes they had greater interpersonal potential to reach a target audience. There was also evidence of intermodal complementarity, or the relations of meaning between modes. The result of the study provides evidence that university brands are created from a combination of modes in their advertising posters and films. The modes feature consistently in the university brand artefacts to communicate the vision and mission relevant to a current strategic plan. The study also reveals that the university logo is a more permanent identity of a university, from which a brand originates.Thesis (Ph.D.) -- University of Adelaide, School of Humanities, 2020

Naskar, Tarun. "Testing of Ground Subsurface using Spectral and Multichannel Analysis of Surface Waves." Thesis, 2017. http://etd.iisc.ernet.in/2005/3775.
Full textAbstract:
Two surface wave testing methods, namely, (i) the spectral analysis of surface waves (SASW), and (ii) the multi-channel analysis of surface waves (MASW), form non-destructive and non-intrusive techniques for predicting the shear wave velocity profile of different layers of ground and pavement. These field testing tools are based on the dispersive characteristics of Rayleigh waves, that is, different frequency components of the surface wave travel at different velocities in layered media. The SASW and MASW testing procedure basically comprises of three different components: (i) field measurements by employing geophones/accelerometers, (ii) generating dispersion plots, and (iii) predicting the shear wave velocity profile based on an inversion analysis.
For generating the field dispersion plot, the complexities involved while doing the phase unwrapping calculations for the SASW technique, while performing the spectral calculations on the basis of two receivers’ data, makes it difficult to automate since it requires frequent manual judgment. In the present thesis, a new method, based on the sliding Fourier transform, has been introduced. The proposed method has been noted to be quite accurate, computationally economical and it generally overcomes the difficulties associated with the unwrapping of the phase difference between the two sensors’ data. In this approach, the unwrapping of the phase can be carried out without any manual intervention. As a result, an automation of the entire computational process to generate the dispersion plot becomes feasible. The method has been thoroughly validated by including a number of examples on the basis of surface wave field tests as well as synthetic test data.
While obtaining the dispersion image by using the MASW method, three different transformation techniques, namely, (i) the Park’s wavefield transform, (ii) the frequency (f) -wavenumber ( ) transform and (iii) the time intercept ( -phase slowness (p) transform have been utilized for generating the multimodal dispersion plots. The performance of these three different methods has been assessed by using synthetic as well as field data records obtained from a ground site by means of 48 geophones. Two-dimensional as well as three-dimensional dispersion plots were generated. The Park’s wavefield transformation method has been found to be especially advantageous since it neither requires a very high sampling rate nor an inclusion of the zero padding of the data in a wavenumber (distance) domain.
In the case of an irregular dispersive media, a proper analysis of the higher modes existing in the dispersion plots becomes essential for predicting the shear wave velocity profile of ground on the basis of surface wave tests. In such cases, the establishment of the predominant mode becomes quite significant. In the current investigation for Rayleigh wave propagation, the predominant mode has been computed by maximizing the normalized vertical displacements along the free surface. Eigenvectors computed from the thin layer approach (TLM) approach are analyzed to predict the corresponding predominant mode. It is noted that the establishment of the predominant mode becomes quite important where only two to six sensors are employed and the governing (predominant) modal dispersion curve is usually observed rather than several multiple modes which can otherwise be identified by using around 24 to 48 multiple sensors.
By using the TLM, it is, however, not possible to account for the exact contribution of the elastic half space in the dynamic stiffness matrix (DSM) approach. A method is suggested to incorporate the exact contribution of the elastic half space in the TLM. The numerical formulation is finally framed as a quadratic eigenvalue problem which can be easily solved by using the subroutine polyeig in MATLAB. The dispersion plots were generated for several chosen different ground profiles. The numerical results were found to match quite well with the data available from literature.
In order to address all the three different aspects of SASW and MASW techniques, a series of field tests were performed on five different ground sites. The ground vibrations were induced by means of (i) a 65 kg mass dropped freely from a height of 5 m, and (ii) by using a 20 pound sledge hammer. It was found that by using a 65 kg mass dropped from a height of 5 m, for stiffer sites, ground exploration becomes feasible even up to a depth of 50-80 m whereas for the softer sites the exploration depth is reduced to about 30 m. By using a 20 lb sledge hammer, the exploration depth is restricted to only 8-10 m due to its low impact energy.
Overall, it is expected that the work reported in the thesis will furnish useful guidelines for (i) performing the SASW and MASW field tests, (ii) generating dispersion plots/images, and (iii) predicting the shear wave velocity profile of the site based on an inversion analysis.

This chapter provides a preliminary account of different figurative operations in twelve examples of program classical and contemporary music involving music and text. The main goals are to explore the directionality and scope of the mappings between language and music and to investigate the communicative effects of each operation in a musical work. Metonymy, metaphor, hyperbole, paradox, and irony are compared and contrasted to highlight the dynamism and flexibility of conceptual mechanisms to account for meaning construction in multimodal contexts. Although all these conceptual tools consist of putting in correspondence two entities, there are differences that allow us to draw boundaries among them. The main advantage of adopting a view based on figurative operations is that they overcome the two-domain layout of metaphors while counting on a limited inferential capacity that allows the prediction of possible communicative effects.

In this chapter, the authors explore the current challenges facing educational institutions to design learning spaces congruent for learning with and through multimodal textual practices. The chapter reviews the inherent design, or grammar, of multimodal literacy practices and that of learning with these texts. Using examples from secondary and tertiary contexts, constructs from complexity theory offer a theoretical lens that is more generative for conceptualizing and analyzing dynamic literacy practices in educational institutions than multimodal literacy. The chapter concludes with a discussion of the tensions that arise form these examples, using Bourdieu’s (1984) habitus to problematize the future of designing dynamic educational spaces.

In translation studies, the term localization is mostly associated with areas connected to new technologies, such as software, websites or computer games. The origins of localization in the form known currently is dated to the mid-1980s, with the dynamic development of computers available to the masses (Schäler 2010). The main aim of this article is to explore whether the concept of localization can be used in a meaningful way to analyse other types of texts in interlingual and intercultural transfer, including texts written before the modern form of localization appeared. The analysis will be illustrated by two case studies taken from the field of children’s literature. The first concerns the Polish rendition of the 19th century classic Der Struwwelpeter while the second one a Polish translation of a contemporary book from the Lesemaus series. Both texts are examples of multimodal texts, that is, picture books for children.

Full textAbstract:
This chapter asks in what ways recent international developments around the notion of interculturality might enrich English language teaching (ELT) in Norway in tandem with the country’s Core Curriculum and English curriculum. To understand the recent trends in intercultural research and their relevance to ELT, an historical background on the teaching of cultural content in the subject of English is provided. The role of interculturality in the Norwegian Core Curriculum and English curriculum is first considered through a textual analysis, then compared and contrasted to the curricula of 1974 and 2006. Next, issues currently under debate and further exploration in the field of interculturality are outlined, focusing particularly on static and dynamic perceptions of culture. Finally, implications for ELT are discussed and activities inspired by an intercultural pedagogy are suggested. In alignment with the focus on multimodal texts in the English subject curriculum and building on research into the affordances of picturebooks for language and intercultural learning, the author proposes that critical analysis of picturebooks and factual texts about topical issues can address the issues under debate. Through such activities, teachers can provide English language students with opportunities to engage the critical perspectives and symbolic competence required to navigate in the 21st century.

Interactive shared picturebook reading with learners of different ages and levels has proven to be a prominent practice in all languages. The overall aim of the chapter is to explore the applicability of shared picturebook reading to teach English as a foreign language. Due to the affordances of the multimodality of picturebooks to develop language and content knowledge, this critical investigation seeks to integrate shared picturebook reading as a mode of instruction into the young learners' academic curriculum to promote oral language abilities and conceptual knowledge. In order to provide practical advice for educators of young learners, the chapter describes ways that picturebooks boost vocabulary, language learning, and conceptual knowledge in English L2. The chapter develops criteria to select picturebooks for subject-area instruction, paying attention to the picture-word dynamics.

Full textAbstract:
As an important task in Sentiment Analysis, Target-oriented Sentiment Classification (TSC) aims to identify sentiment polarities over each opinion target in a sentence. However, existing approaches to this task primarily rely on the textual content, but ignoring the other increasingly popular multimodal data sources (e.g., images), which can enhance the robustness of these text-based models. Motivated by this observation and inspired by the recently proposed BERT architecture, we study Target-oriented Multimodal Sentiment Classification (TMSC) and propose a multimodal BERT architecture. To model intra-modality dynamics, we first apply BERT to obtain target-sensitive textual representations. We then borrow the idea from self-attention and design a target attention mechanism to perform target-image matching to derive target-sensitive visual representations. To model inter-modality dynamics, we further propose to stack a set of self-attention layers to capture multimodal interactions. Experimental results show that our model can outperform several highly competitive approaches for TSC and TMSC.

Considering the complexity of propulsion plant and the multiple operating conditions for fishing vessel, the modeling and simulation of ship engine propeller and net for the ocean-going fishing vessel are investigated. According to the matching theory of ship engine propeller and net, the relationships of them are analyzed. Furthermore, the motion balance equation and dynamic equilibrium equation are built for the translation system and rotation system of fishing vessel which can indicate the changing trends of propeller rotational speed or ship speed and propeller torque of thrust. Based on this, by setting up the simulation models of various subsystems, the simulation model of propulsion plant are built for the ocean-going fishing vessel. A trawler is considered to perform simulation tests in which start-up condition, normal navigation condition and trawling condition are taken into account. The simulation results illustrate the correctness and validity of modeling and simulation for propulsion plant system.

We consider the problem of project success prediction on crowdfunding platforms. Despite the information in a project profile can be of different modalities such as text, images, and metadata, most existing prediction approaches leverage only the text dominated modality. Nowadays rich visual images have been utilized in more and more project profiles for attracting backers, little work has been conducted to evaluate their effects towards success prediction. Moreover, meta information has been exploited in many existing approaches for improving prediction accuracy. However, such meta information is usually limited to the dynamics after projects are posted, e.g., funding dynamics such as comments and updates. Such a requirement of using after-posting information makes both project creators and platforms not able to predict the outcome in a timely manner. In this work, we designed and evaluated advanced neural network schemes that combine information from different modalities to study the influence of sophisticated interactions among textual, visual, and metadata on project success prediction. To make pre-posting prediction possible, our approach requires only information collected from the pre-posting profile. Our extensive experimental results show that the image features could improve success prediction performance significantly, particularly for project profiles with little text information. Furthermore, we identified contributing elements.

The article considers the forming a pool of regression tests when using the CI/CD process in the development of information systems consisting of a significant number of interacting modules and using various database management systems. The reasons that do not allow using standard filters of testing management systems to account for possible interactions between modules of the developed information system are indicated. The method of selection of the tests to consider the interaction and potential mutual influence of modules on each other, which also minimizes the pool of selected tests, and rank tests for significance from the point of view of a decision on the correctness of the implementation of the functionality of the information system and the system's readiness for its transfer to the customer. The method of dynamic selection of tests that allow to quickly evaluate changes made to the components of the information system in terms of possible negative impact on the unaffected components and functionality is considered. The advantages and disadvantages of the considered methodology, the necessary conditions for its successful application, and ways to implement it both in new projects for the development of information systems and in existing projects in continuous development and without the possibility of organizing code freezing are given.

Multimodel wearable sensor data classificationplays an important role in ubiquitous computingand has a wide range of applications in variousscenarios from healthcare to entertainment. How-ever, most of the existing work in this field em-ploys domain-specific approaches and is thus inef-fective in complex situations where multi-modalitysensor data is collected. Moreover, the wearablesensor data is less informative than the conven-tional data such as texts or images. In this paper,to improve the adaptability of such classificationmethods across different application contexts, weturn this classification task into a game and applya deep reinforcement learning scheme to dynami-cally deal with complex situations. We also intro-duce a selective attention mechanism into the rein-forcement learning scheme to focus on the crucialdimensions of the data. This mechanism helps tocapture extra information from the signal, and canthus significantly improve the discriminative powerof the classifier. We carry out several experimentson three wearable sensor datasets, and demonstratecompetitive performance of the proposed approachcompared to several state-of-the-art baselines.

Full textAbstract:
Acoustically induced vibration (AIV) is a high-frequency vibration phenomenon that can occur downstream of pressure-reducing devices such as control valves, restriction orifices, and pressure relief or safety valves in compressor piping systems. These vibrations can lead to high cycle fatigue failures of downstream piping at side branches or welded supports. Existing methods for screening and analyzing acoustically induced vibration are not well-grounded in the underlying physics and thus do not provide a methodology for evaluating a variety of mitigation strategies. Modeling of acoustically induced vibration is computationally challenging, as it requires the interaction between tens or hundreds of higher-order acoustic modes with a similar number of piping shell modes. In order to obtain better insight into the underlying physics of AIV and to characterize the effectiveness of several mitigation methods, full-scale blow-down testing was performed at Southwest Research Institute. Tests were performed using 20 MPa nitrogen gas vented at 28 kg/s through a 3×4” pressure safety valve and multiple header pipe sizes ranging from 12” to 36”. Test configurations included baseline piping geometry at each size and several AIV mitigations including stiffening rings, viscous damping wrap, and internal acoustic mode disruptors. Test results from strain gauges, accelerometers, and dynamic pressure transducers show a broadband multimodal response with dynamic stresses up to 3 kHz near the safety valve tailpipe connection to the test header, and various mitigations reduced dynamic stresses by 8–52% depending on the piping and type of mitigation. Acoustic and structural finite element models were analyzed in order to determine the coincident modes that match in both axial/circumferential shape and natural frequency and compare coincident frequencies with measure stresses. The results show that observed peak stress frequencies do not generally correlate well with predicted coincident modes, and that flow-induced turbulence excites frequencies below piping shell modes that can also result in significant stresses that combine with AIV.

Full textAbstract:
Abstract Project BRUTE has investigated weld materials extracted from the decommissioned Barsebäck 2 reactor pressure vessel. The materials investigated originate from the pressure vessel head (RPVH) and beltline regions. The performed mechanical testing include tensile, Charpy impact and fracture toughness testing. Tensile testing with miniature specimens demonstrates a difference of over 50 MPa in the yield and ultimate tensile strengths of the RPVH and beltline materials. Beltline specimens tested at the operating temperature exhibit discontinuity past the yield region, possibly indicating dynamic strain aging. Charpy impact tests were performed around the transition region of the material. Transition curves were fitted, and reference temperatures T28J of −85 °C and −106 °C were determined for RPVH and beltline materials, respectively. This indicates better material properties at beltline compared to the RPVH, in agreement with tensile results. The reference temperatures T28J were further utilized to estimate brittle fracture initiation toughness reference temperatures T0. Fracture toughness testing follows the Master Curve methodology defined in ASTM standard E1921. Reference temperatures T0 were determined at −115.1 °C and −101.1 °C for the RPVH and beltline, respectively, but the tests indicate inhomogeneity in both materials. The mean reference temperatures of the multimodal models TM were determined at −110.0 °C and −96.5 °C, and the associated, margin adjusted lower confidence bounds TM5%, MA at −13.3 °C and −53.0 °C for the RPVH and beltline materials, respectively. The latter values indicate that the inhomogeneity is more extensive in the RPVH. The estimates obtained from the Charpy impact toughness results do not correlate consistently with the fracture toughness-based transition temperature, possibly due to the inhomogeneity of the materials. The results show that the safety of the materials can be assessed reliably, provided that contemporary methods, equipment and analyses are used.

"A Cost-Effective Stimulation Workflow Unlocks New Perspectives for Matrix Acidizing in Openhole Horizontal Tight Carbonate – A Case Study from West Kuwait." In SPE Annual Technical Conference and Exhibition. SPE, 2021. http://dx.doi.org/10.2118/206133-ms.
Full textAbstract:
Abstract The Mishrif formation in west Kuwait is a tight carbonate reservoir having low oil mobility. It is fractured and heterogeneous with wide variation in porosity ranging from 10 to 25%, matrix permeability of about 0.1 to 10 md, and 20°API oil. Production tests and geomechanical study results have revealed that productivity is mostly from the high-permeability matrix and critically stressed fracture networks. Recently, the Mishrif development has been dominated by horizontal wells to maximize reservoir contact and enhance productivity. However, a challenge in such openhole completion is the stimulation strategy requiring effective diversion technology due to the uneven acid distribution along the lateral section. To address those challenges, a novel engineered workflow has been implemented relying on distributed temperature sensing (DTS) to assess the fluid coverage across the openhole section. Results enable identifying high- and low-intake zones, segmenting the uncased section into intervals requiring different levels of stimulation, and making informed decisions regarding diversion requirements. The intervention was conducted in two stages. Coiled tubing (CT) was the selected fluid conveyance method on the first stage given its capacity for more controlled fluid placement, and high-rate bullheading stimulation was selected for the second stage. During the treatment, multiple challenges were faced, mainly driven by a high-permeability streak identified by the DTS near the heel of the lateral. The CT stimulation procedures were modified on the spot, and measures were taken to minimize the impact on the thief zone, which included a combination of diversion techniques, such as high-pressure jetting, dual injection, and pumping of a near-wellbore nonreactive diverter, which is composed of a customized blend of multimodal particles and degradable fibers to minimize fluid leakoff into the high-intake zone. Likewise, real-time downhole telemetry was crucial throughout the CT stimulation because it allowed the highest injection rate possible below the preset pressure limits, continuous monitoring of downhole dynamics along the intervention, and optimal actuation of the high-pressure jetting tool. Upon completion of the CT stimulation, a second DTS log was carried out to evaluate the fluid coverage and effectiveness of the diversion strategy, enabling further adjustment of the bullhead stimulation program. This stimulation workflow implemented in west Kuwait represents a cost-effective alternative to stimulate openhole tight carbonates. This study brings new perspectives for treating complex reservoirs in the region, and shares lessons learned for future interventions.

As urbanization progresses in China's rural areas, so do the severity of social issues, including the decline of social assets, the recession of agricultural industries, the lack of community cohesion, and a weak sense of belonging. A decline in cultural awareness is the reason behind such phenomena, which stems from changes to residents' lifestyles and a lack of cultural beliefs. This issue also results in insufficient cultural awareness, weak cultural inheritance, and neglect of cultural values among community residents. To this end, this paper aims to examine an educational model to enhance the cultural awareness of local community residents.At present, there are two types of education methods to enhance cultural awareness: passive types and active types. For example, passive education refers to the enhancement of participants’ cultural qualities through the problem-solving style lesson and ‘implicit’ curriculum, while an active education might use reflective writing or PD to promote cultural awareness. Of the two, active education, represented by PD, is more conducive to participants' acceptance of cultural knowledge. PD is also an effective method for developing humanitarianism in developing countries. It can be applied to the special scenario of rural communities in China as a new solution for raising the cultural awareness of residents. This paper shares a specific case study of enhancing residents' cultural awareness in community collective memory using participatory game design.A total of eight subjects were selected in this study. Since children are the future of the community's cultural development, the subjects included 6 children and 2 adults. Unlike traditional PD, this study focused on attracting the interests of subjects and enhancing their abilities to inherit traditional culture through participatory game design. The study consisted of three workshops: the cultural exploration workshop, the game design workshop, and the game testing workshop. Activity theory was used as a basis to guide the choice of time, location, and power dynamics, from which a framework of participatory activities covering the four approaches of "probing", "telling", "acting", and "making" was developed for the workshops. To further enhance collaboration, participants were also provided with a complete set of toolkits during the three workshops, including role-playing tools, game idea cards, house of cards, scaffolding, etc. At the end of each workshop, the Cultural Awareness Scale, which contains the three elements of cultural cognition, cultural heritage, and cultural values, was administered to measure the change in cultural awareness of the subjects. A mixed methods approach was used in analysis to uncover underlying cultural associations. The study qualitatively analyzed the transcribed spoken words and behaviors of the subjects using multimodal analysis, and quantitatively analyzed the variations in the word count of the text and the level of detail in the elaboration. In summary, this case study is important for examining cultural education models and improving the cultural awareness of the population. It also provides a framework of activities for participatory design workshops, which can serve as a reference for further research.
