Abstract:
Visual short-term memory (VSTM) enables humans to form a stable and coherent representation of the external world. However, the nature and temporal dynamics of the neural representations in VSTM that support this stability are barely understood. Here we combined human intracranial electroencephalography (iEEG) recordings with analyses using deep neural networks and semantic models to probe the representational format and temporal dynamics of information in VSTM. We found clear evidence that VSTM maintenance occurred in two distinct representational formats which originated from different encoding periods. The first format derived from an early encoding period (250 to 770 ms) corresponded to higher-order visual representations. The second format originated from a late encoding period (1,000 to 1,980 ms) and contained abstract semantic representations. These representational formats were overall stable during maintenance, with no consistent transformation across time. Nevertheless, maintenance of both representational formats showed substantial arrhythmic fluctuations, i.e., waxing and waning in irregular intervals. The increases of the maintained representational formats were specific to the phases of hippocampal low-frequency activity. Our results demonstrate that human VSTM simultaneously maintains representations at different levels of processing, from higher-order visual information to abstract semantic representations, which are stably maintained via coupling to hippocampal low-frequency activity.

Abstract:
The aim of this paper is to introduce a new concept of scientific representation into philosophy of science. The new concept -to be called homological or functorial representation- is a genuine generalization of the received notion of representation as a structure preserving map as it is used, for example, in the representational theory of measurement. It may be traced back, at least implicitly, to the works of Hertz and Duhem. A modern elaboration may be found in the foundational discipline of mathematical category theory. In contrast to the familiar concepts of representations, functorial representations do not depend on any notion of similarity, neither structural nor objectual one. Rather, functorial representation establish correlations between the structures of the representing and the represented domains. Thus, they may be said to form a class of quite "non-isomorphic" representations. Nevertheless, and this is the central claim of this paper, they are the most common type of representations used in science. In our paper we give some examples from mathematics and empirical science. One of the most interesting features of the new concept is that it leads in a natural way to a combinatorial theory of scientific representations, i.e. homological or functorial representations do not live in insulation, rather, they may be combined and connected in various ways thereby forming a net of interrelated representations. One of the most important tasks of a theory of scientific representations is to describe this realm of combinatorial possibilities in detail. Some first tentative steps towards this endeavour are done in our paper.

Abstract:
In the quest for efficient and robust reinforcement learning methods, both model-free and model-based approaches offer advantages. In this paper we propose a new way of explicitly bridging both approaches via a shared low-dimensional learned encoding of the environment, meant to capture summarizing abstractions. We show that the modularity brought by this approach leads to good generalization while being computationally efficient, with planning happening in a smaller latent state space. In addition, this approach recovers a sufficient low-dimensional representation of the environment, which opens up new strategies for interpretable AI, exploration and transfer learning.

Abstract:
In language, stored semantic representations of lexical items combine into an infinitude of complex expressions. While the neuroscience of composition has begun to mature, we do not yet understand how the stored representations evolve and morph during composition. New decoding techniques allow us to crack open this very hard question: we can train a model to recognize a representation in one context or time-point and assess its accuracy in another. We combined the decoding approach with magnetoencephalography recorded during a picture naming task to investigate the temporal evolution of noun and adjective representations during speech planning. We tracked semantic representations as they combined into simple two-word phrases, using single words and two-word lists as non-combinatory controls. We found that nouns were generally more decodable than adjectives, suggesting that noun representations were stronger and/or more consistent across trials than those of adjectives. When training and testing across contexts and times, the representations of isolated nouns were recoverable when those nouns were embedded in phrases, but not so if they were embedded in lists. Adjective representations did not show a similar consistency across isolated and phrasal contexts. Noun representations in phrases also sustained over time in a way that was not observed for any other pairing of word class and context. These findings offer a new window into the temporal evolution and context sensitivity of word representations during composition, revealing a clear asymmetry between adjectives and nouns. The impact of phrasal contexts on the decodability of nouns may be due to the nouns’ status as head of phrase—an intriguing hypothesis for future research.

Abstract:
To date, it is commonly agreed that physical practice, as well as mental types of practice, have the potential to bring about improvements in motor performance and to induce motor learning. The perceptual-cognitive representational background of these changes, however, is still being debated. In this experiment, we investigated the influence of observational practice on the performance and the representation of the golf putt. With this we aimed at adding to the ongoing debate on the particular contribution of observational practice to motor learning. Novices were assigned to one of two groups: observational and combined observational and physical practice. Motor performance and mental representation were measured prior to and after practice and after a three-day retention interval. Performance improved in both practice groups from pre- to retention-test. Together with performance improvements, mental representation structures developed functionally and became more elaborate over the course of the experiment. Interestingly, however, the pattern of changes over the course of the experiment and across the two practice types was different. Combined practice led to improvements in motor performance from pre- to post-test with representations developing alongside these improvements. Observational practice alone did not lead to performance improvement until after task execution, as shown by improvements in motor performance from post- to retention-test, even though mental representations changed from pre- to post-test. From this, observational practice seems to promote the development of representational frameworks of complex action, and thus action-related order formation in long-term memory.

Abstract:
This paper presents a formal framework for the combination of document representations based on evidential reasoning. Each indexing method is modelled by an agent referred to as an indexer. Indexing elements re modelled as sentences which are used to describe the content of a document. The modelling of the indexing and its uncertainty provides the document representation. The combination of document representations is expressed as the combination of the indexing and uncertainty as provided by two or more indexers. The resulting indexer is referred to as the combined indexer. The proposed framework allows the capture of the semantics of the indexing vocabularies associated with the indexers and the aggregation of the uncertainty associated with the indexing.

Abstract:
Abstract Pioneering research established the concept of somatotopic organization of the primary motor and somatosensory cortex along the central sulcus as depicted in the widely known schematic illustration (the “homunculus”) by Penfield and colleagues. With the exception of the hand, however, a precise relationship between morphological features of the central sulcus and the representation of various parts of the body has not been addressed. To investigate whether such relations between anatomical features and functional body representations exist, we first examined central sulcus morphology in detail and then conducted a functional magnetic resonance imaging experiment to establish somatomotor representations. This study established that the central sulcus is composed of five distinct sulcal segments and demonstrated that each segment relates systematically to the sensorimotor representation of distinct parts of the body. Thus, local morphology predicts the localization of body representations with precision, raising fundamental questions regarding functional and morphological differentiation.

Abstract:
In this article, we propose that elements of heritage language grammars—both in the form of axiomatic features and larger combined representational units—are not easily lost over the course of the lifespan. This view contrasts with alternative explanations for the steady-state representation of these grammars that suggest truncated acquisition or erosion are the primary culprits of perceived language loss. In production and comprehension processes for heritage bilinguals, particular elements are more difficult to access than others, leading to differential ways to access representations and feature values. To illustrate and support this hypothesis, we build on previous work by examining the interpretation and use of obligatory mood selection in Spanish desiderative constructions in three groups of heritage speakers with different levels of language proficiency.

Abstract:
As traditional text representations are not suitable for online dynamic streams, this paper presents a hot topic extraction technique that can be used for tracking news topics over time. The model combines individual word burst into the document-word vector representation, which can emphasize the temporally features of text streams. An energy ratio threshold based burst detection approach is proposed and TF-PDF is then combined to weigh the terms. Experiment results demonstrate that this model is effective in topic extraction for news stream and it can better improve the clustering performance.

Full text
Abstract:
This thesis investigates continuities and change in the visualization of the hero in 1960s English football, a period of transition for the player from traditional to modern football practices. It does so from a socio-historical perspective. Its principal aim has been to explore the media representation of the evolution of the visual image of the football hero. This through the study of primary source archive material in the form of media images held by the National Football Museum archive and the National Photographic collection at the National Media Museum. In addition a corpus of contemporary images published in the mass and sports media of the day are considered, along with objects of material culture pertinent to the eulogy of the football hero. In so doing the research looks to understand if the theoretical hero typologies of previous sociological studies are evident in the actual historic visual portrayal of the time. The study of the historic visual culture of football is of relevance given the corporeal nature of the game and the prevalence of the image in communicating its narrative. However, the interrogation of the visual record is an under-utilised research tool in sports history. This research then looks to play a part in addressing this omission in its contribution to the understanding of what constitutes a football hero. The thesis firstly considers theoretical hero typologies appropriate to the football context. It then provides a chronological synopsis of the visualisation of the hero footballer in the period preceding that of this particular study, the 1960s. The chronological structure is continued in the specific study of the Sixties decade. Individual hero players are considered in each chapter as redolent of relevant hero types. Visual references are included as examples at the conclusion of each chapter. Based on the visual evidence the thesis finds that, unlike those sociological typologies that tend to be presented sequentially, visual representations of the hegemonic football hero are continuous, gradualist and emergent. It establishes that the synthesis of change in player socio-economic circumstance and coterminous media advances combines to influence both the on-field and off-duty representation of the football hero. It also challenges the assertion that cultural and aesthetic decisions dominate technological determinism, by suggesting that the commercial imperative plays a central role in shaping the image of the football hero.

Abstract:
South Africa has long been associated with racial and ethnic issues surrounding prejudice and discrimination and despite a move post-1994 to a democratic ‘rainbow nation’ society, the country has remained plagued by unequal power relations. One such instance of inequality relates to the marginalisation of migrants which has been realised through xenophobic attitudes and actions, most notably the violence that swept across the country in 2008. Several reasons have been suggested in an attempt to explain the cause of the violence, including claims that migrants are taking ‘our jobs and our women’, migrants are ‘illegal and criminal’ and bringing ‘disease and contamination’ with them from their countries of origin. Although widely accepted that many, if not all, of these beliefs are based on ignorance and hearsay, these extensive generalisations shape and reinforce prejudiced ideologies about migrant communities. It is thus only when confronted with evidence that challenges this dominant discourse, that South Africans are able to reconsider their views. Williams (2008) suggests that for many South Africans, Africa continues to be the ‘dark continent’ that is seen as an ominous, threatening force of which they have very little knowledge. For this reason, anti-immigrant sentiment in a South African context has traditionally been directed at African foreigners. In this study I examine the ways in which African migrants and migrant communities, as well as the overall processes of migration, are depicted by selected South African print media: City Press, Mail & Guardian and Sunday Times. Using a combined Corpus Linguistics and Critical Discourse Analysis approach, I investigate the following questions: How are migrants and the process of migration into South Africa represented by these established newspapers between 2006 and 2010? Are there any differences or similarities between these representations? In particular, what ideologies regarding migrants and migrant communities underlie these representations? My analysis focuses on the landscape of public discourse about migration with an exploration of the rise and fall of the terminologies used to categorise migrants and the social implications of these classifications. Additionally, I analyse the expansive occurrences of negative representations of migrants, particularly through the use of ‘othering’ pronouns ‘us’ versus ‘them’ and through the use of metaphorical language which largely depicts these individuals as en masse natural disasters. I conclude that these discursive elements play a crucial role in contributing to an overall xenophobic rhetoric. Despite subtle differences between the three newspapers which can be accounted for based on their political persuasions and agendas, it is surprising to note how aligned these publications are with regard to their portrayal of migrants. With a few exceptions, this representation positions these individuals as powerless and disenfranchised and maintains the status quo view of migrants as burdens on the South African economy and resources. Overall, the newspaper articles contribute to mainstream dominant discourse on migrants and migration with the underlying ideology that migrants are responsible for the hardships suffered by South African citizens. Thus, this study contributes significantly to existing bodies of research detailing discourse on migrants and emphasises the intrinsic links between language, ideology and society.

Abstract:
This practice-based project explores the photographic phenomenon of ‘moment beyond moment’, which refers to the combined representations of an existing image in an environment, together with the real-life situation at the moment the photograph is taken. I call this photograph an ‘extended photograph’. Employing practical works of extended photographs and focusing on interactions between the moment in real-life and the moment in an existing image, the research explores the transformation of meanings caused by the interactions of these moments in an extended photograph. The research owes its approach to grounded theory, contrary thinking and Chinese Buddhist ‘Sudden Enlightenment’ to further its aim of exploring the unpredictable interaction of these moments, and to disclose the potentials of meaning transformation. My research outcome intends to initiate a discourse with photographic practitioners and theorists on the phenomenon of moment beyond moment in a working environment that is encaged by the excessive existence of displayed images. The thesis is composed as a creative work that consists of a series of photographic images accompanied by an exegesis component. The images represent a nominal 80%, and the exegesis 20% of the final submission.

Full text
Abstract:
A programmer wishing to make a change to a piece of code must first gain a full understanding of the behaviours and functionality involved. This process of program comprehension is difficult and time consuming, and often hindered by the absence of useful program documentation. Where documentation is absent, static analysis techniques are often employed to gather programming level information in the form of data and control flow relationships, directly from the source code itself. Software maintenance environments are created by grouping together a number of different static analysis tools such as program sheers, call graph builders and data flow analysis tools, providing a maintainer with a selection of 'views' of the subject code. However, each analysis tool often requires its own intermediate program representation (IPR). For example, an environment comprising five tools may require five different IPRs, giving repetition of information and inefficient use of storage space. A solution to this problem is to develop a single combined representation which contains all the program relationships required to present a maintainer with each required code view. The research presented in this thesis describes the Combined C Graph (CCG), a dependence-based representation for C programs from which a maintainer is able to construct data and control dependence views, interprocedural control flow views, program slices and ripple analyses. The CCG extends earlier dependence-based program representations, introducing language features such as expressions with embedded side effects and control flows, value returning functions, pointer variables, pointer parameters, array variables and structure variables. Algorithms for the construction of the CCG are described and the feasibility of the CCG demonstrated by means of a C/Prolog based prototype implementation.

Abstract:
This thesis proposes an approach to provide a visually realistic interactive simulation of the effect of removing rigid bounded volumetric portions of a 3D object. The approach processes the volume removal at sufficient rates for realistic real-time rendering, while minimizing the error caused during volume removal operations. We refer to these volume removal operations as 3D carving. 3D carving is particularly applicable to the computer simulation of bone-surgery medical procedures performed with a motorized burr tool; however the methods and algorithm presented are generic enough to be used for other purposes such as 3D modeling, destructible objects in 3D games and others. Our approach represents the volume of the object being carved using voxels while displaying the object to the user using an associated polygonal mesh. We use the Ball-Pivoting Algorithm---which has been traditionally used to generate a triangle mesh from a point cloud---to generate the mesh associated with the voxels, but we present a novel extension to the algorithm, the Dynamic Ball-Pivoting Algorithm, so that local changes to the voxel set only require local changes to the mesh, whereas the standard algorithm would require a global remeshing. We demonstrate how to apply 3D and 2D textures simultaneously to provide separate external and internal textures for objects that have different skin and internal appearances, which increases the realism of the visualization. We provide measurements of the performance and accuracy of our approach.

Abstract:

The thesis presents a user interface design aimed at the scenario where a dual representation of a volume is desired in order to emphasize certain parts of a volume using surface graphics while the rest of the volume is rendered using direct volume rendering techniques. A typical situation in which this configuration can prove useful is when studying images acquired for medical purposes. Sometimes the user wants to identify and represent an organ using an opaque surface in an otherwise partly opaque visualization of the volume data set. The design is based on the visualization library VTK along with Trolltech Qt, a GUI Toolkit in C++. The choice of using VTK as a visualization library was made after evaluating similar systems. The report includes a state of the art chapter, the requirements for the system, the system design and the results achieved after implementing the design are shown.

Abstract:
Recent research makes use of biologically inspired computation and artificial intelligence as efficient means to solve real-world problems. Humans show a significant performance in extracting and interpreting visual information. In the cases where visual data is not available, or, for example, if it fails to provide comprehensive information due to occlusions, tactile exploration assists in the interpretation and better understanding of the environment. This cooperation between human senses can serve as an inspiration to embed a higher level of intelligence in computational models. In the context of this research, in the first step, computational models of visual attention are explored to determine salient regions on the surface of objects. Two different approaches are proposed. The first approach takes advantage of a series of contributing features in guiding human visual attention, namely color, contrast, curvature, edge, entropy, intensity, orientation, and symmetry are efficiently integrated to identify salient features on the surface of 3D objects. This model of visual attention also learns to adaptively weight each feature based on ground-truth data to ensure a better compatibility with human visual exploration capabilities. The second approach uses a deep Convolutional Neural Network (CNN) for feature extraction from images collected from 3D objects and formulates saliency as a fusion map of regions where the CNN looks at, while classifying the object based on their geometrical and semantic characteristics. The main difference between the outcomes of the two algorithms is that the first approach results in saliencies spread over the surface of the objects while the second approach highlights one or two regions with concentrated saliency. Therefore, the first approach is an appropriate simulation of visual exploration of objects, while the second approach successfully simulates the eye fixation locations on objects. In the second step, the first computational model of visual attention is used to determine scattered salient points on the surface of objects based on which simplified versions of 3D object models preserving the important visual characteristics of objects are constructed. Subsequently, the thesis focuses on the topic of tactile object recognition, leveraging the proposed model of visual attention. Beyond the sensor technologies which are instrumental in ensuring data quality, biological models can also assist in guiding the placement of sensors and support various selective data sampling strategies that allow exploring an object’s surface faster. Therefore, the possibility to guide the acquisition of tactile data based on the identified visually salient features is tested and validated in this research. Different object exploration and data processing approaches were used to identify the most promising solution. Our experiments confirm the effectiveness of computational models of visual attention as a guide for data selection for both simplifying 3D representation of objects as well as enhancing tactile object recognition. In particular, the current research demonstrates that: (1) the simplified representation of objects by preserving visually salient characteristics shows a better compatibility with human visual capabilities compared to uniformly simplified models, and (2) tactile data acquired based on salient visual features are more informative about the objects’ characteristics and can be employed in tactile object manipulation and recognition scenarios. In the last section, the thesis addresses the issue of transfer of learning from vision to touch. Inspired from biological studies that attest similarities between the processing of visual and tactile stimuli in human brain, the thesis studies the possibility of transfer of learning from vision to touch using deep learning architectures and proposes a hybrid CNN that handles both visual and tactile object recognition.

Abstract:
La Seconde Guerre mondiale occupe une place centrale dans la mémoire collective britannique. Érigée en véritable mythe national, la guerre a une telle prégnance dans l’espace public en Grande-Bretagne que certains commentateurs n’hésitent pas à parler d’une obsession nationale pour le conflit. Elle en vient à constituer l’une des facettes de la « Britishness », de l’identité nationale britannique, à une heure où celle-ci est plus que jamais débattue et soumise au questionnement. Afin de déterminer si la Seconde Guerre mondiale est un mythe britannique ou un mythe anglais, ses représentations dans les pays constitutifs du Royaume-Uni et en Irlande sont ici étudiées. Les aspirations nationalistes écossaises semblent en effet avoir une influence sur les représentations de la guerre en Écosse ; quant à l’Irlande, bien qu’elle soit restée neutre pendant le conflit, cette neutralité est aujourd’hui remise en question au profit d’une interprétation selon laquelle le pays aurait soutenu sans réserve – quoique tacitement – les Alliés. Alors que le visage de la Grande-Bretagne est résolument multi-ethnique, cette étude cherche à déterminer dans quelle mesure les anciens peuples coloniaux et du Commonwealth se reconnaissent dans les représentations traditionnelles dominantes. Au coeur d’une vague de commémoration de la Seconde Guerre mondiale sans précédent, un exemple fait figure d’exception : celui des équipages du Bomber Command. Longtemps critiqués et mis à l’écart des pratiques commémoratives et de la mémoire collective britannique de la Seconde Guerre mondiale en raison de leur participation à la très controversée campagne aérienne stratégique (dont les bombardements firent des dizaines de milliers de victimes parmi les populations civiles allemandes), les équipages du Bomber Command sont aujourd’hui élevés au rang de héros en Grande-Bretagne. Le tout nouveau statut héroïque du Bomber Command marque un tournant dans l’historiographie de la campagne aérienne stratégique et dans le débat public britannique
The Second World War occupies a central place in British collective memory. The war, which is considered to be a national myth in Britain, remains pervasive in the British public debate to the point that some commentators call it a national obsession. The war constitutes one of the facets of Britishness at a time when British national identity is much debated and open to question. The representations of the Second World War in Scotland, Wales and Ireland are examined in order to determine whether the war is a British myth or an English myth. Scottish nationalist aspirations, for instance, seem to have an influence on the way the conflict is represented in Scotland. At a time when Britain is more than ever ethnically diverse, this study seeks to determine the extent to which former colonial peoples are able to recognise themselves in the traditional representations of the war which dominate the public debate in Britain. In the midst of an unprecedented boom in remembrance, the Bomber Command crews are an exception. Although their role in the combined bomber offensive (which caused thousands of victims among the German civilian population) had been subjected to much criticism and excluded bomber crews from the myth of the war, they are now hailed as heroes in Britain. Bomber Command’s newly-found heroic status is a turning point in the historiography of the air offensive and the British public debate

Abstract:
Le but de notre travail est de définir un modèle de recherche d'informations, intégrant les deux modes d'accès que sont la formulation de requêtes (approche systèmes de recherche d'information) et la navigation (approche systèmes hypermédia). La motivation de cette étude repose sur la constatation que ces deux approches sont fortement complémentaires, les avantages de l'une compensant largement les limitations de l'autre. Classiquement, les modèles de recherche d'informations et d'hypermédia établissent une distinction entre les aspects structure des informations et les aspects représentation des connaissances. Cette distinction est, d'une part, de nature à limiter les possibilités de ces systèmes, et est un obstacle à l'intégration de ces deux modèles d'autre part. La base de notre approche d'intégration consiste tout d'abord à unifier ces deux types d'informations: une sémantique est attachée aux structures, et cette sémantique doit être explicitée et utilisée dans le processus d'accès à l'information, au même titre que les connaissances attachées au contenu de l'information. La définition formelle proposée du modèle intégré est largement fondée sur le formalisme des graphes conceptuels qui a été retenu pour représenter toutes les connaissances du système et pour réaliser les différentes opérations d'interrogation et de navigation propres aux deux approches. Une conclusion intéressante de cette démarche d'intégration est qu'elle conduit également à améliorer les deux modèles composants, par rapport à l'état de l'art. Une expérimentation du modèle proposé a conduit à la réalisation d'un prototype fondé sur O2 (SGBD Orienté Objet) et l'interface MOSAIC de WWW (World Wide Web), et les tests ont utilisé le corpus du système RIME (Recherche d'Informations MEdicales)

Abstract:
Playful representations of history are quite widespread in various types of modern toys and games. The author of this essay focused specifically on commercially available construction sets inspired by Greek antiquity. In order to acquire an understanding of user behaviour vis à vis such playthings, she employed as sources consumer reactions published on on line marketplaces. User generated feedback that is available on the Internet clearly offers an extremely rich and relatively untapped resource for researchers of user experiences. The on line exploration was complemented by a self study of using one of these sets to construct a mini Parthenon; it was a pleasurable and rewarding activity The combined consideration of consumer comments and self study suggest that the experience of making miniature replicas of ancient buildings is mostly positive for a wide range of users, as it successfully combines entertainment with learning. At the same time, such play activities offer sufficient scope for improvisation and creativity.

Abstract:
Finite element (FE) models of the spine have been used to assess natural and pathological spine mechanics and evaluate performance of various fusion and posterior stabilization devices [1–3]; however, analysis times may be prohibitive for clinical and design phase assessments. Muscle-actuated, rigid body models have also been developed and used to estimate spinal loading conditions during simulated activities [4]. Although rigid body dynamics platforms typically require less computational time, they are unable to evaluate internal stresses and strains in deformable structures. This study proposes to develop a combined rigid – deformable surrogate spine model where the behavior of the intervertebral disc, facet cartilage and ligaments are replicated by simulated mechanical constraint at desired levels. The explicit FE platform is able to accommodate the spectrum of representations, including fully deformable, fully rigid body, implanted, or any combination. Accordingly, the objective of the current study was to assess the ability of a combined rigid-deformable spine model to accurately reproduce the behavior of the fully deformable representation in the natural state with improved computational efficiency. Specifically, this study compared results for a lumbar (L1-L5) spine under follower load and moment conditions for representations ranging from fully deformable to fully rigid. The combined rigid-deformable model includes the deformable disc, facet cartilage contact, ligament representations at L4-L5, while the other levels are modeled using a simplified mechanical constraint.

Abstract:
Many representations exist for describing engineering artifacts. These representations come from a wide variety of work in many research areas with differing backgrounds and purposes. No unified representation has emerged combining aspects of existing schemes with an ability to easily grow and be extended over time. In this work we demonstrate the application of methods from the knowledge representation community to the domain of engineering artifacts, in particular electromechanical assemblies. We use conceptual graphs as a formal, cleanly extensible representation form. Aspects of several existing results are combined to create a unified representation and demonstrate the approach. We also discuss translation of the conceptual graphs to the DARPA Agent Markup Language (DAML) in order to utilize and cooperate with efforts to develop ontologies for this domain.

Abstract:
Pseudo-rigid-body models help expedite the compliant mechanism design process by aiding the analysis and synthesis of candidate design solutions, using loop-closure techniques for rigid-body mechanisms. Presently, these models are available only for relatively simple compliant beam geometries and loading situations. The pseudo-rigid-body model chain algorithm provides reasonable approximations of the deformed shape of complex compliant members; however, it has one major limitation. The elastic deformation of each compliant segment under combined load boundary conditions is obtained by superposing the pseudo-rigid-body model displacements due to i) the force and ii) the moment loads, respectively. Hence, each segment needs to be characterized by two separate pseudo-rigid-body models in order to accurately determine its deformation kinematics. Such an idealization of compliant segments would present significant challenges when attempting to represent the pseudo-rigid-body model chain in vectorial form, as in planar vector loop-closure methods. Vectorial modeling would be possible if each flexible segment in the chain could be represented by an “equivalent pseudo-rigid-body model.” This paper proposes the concept of a rudimentary equivalent pseudo-rigid-body model to represent compliant segments with combined load boundary conditions in the pseudo-rigid-body model chain algorithm. Such a model may help overcome the difficulties confronted in the potential implementation of the pseudo-rigid-body model chain in planar vector loop-closure solution techniques.

Abstract In this paper, three new representations of a line-segment are introduced that combine Plücker line coordinates with specifications of length and location of a line-segment. For each of the three line-segment representations, a right conoidal interpolant of two arbitrarily disposed line-segments is developed. These interpolants are then combined with deCasteljau-like algorithms for generating ruled surfaces. The results can be extended to develop new algorithms for computer aided geometric design of geometric shapes based on line geometry.

Abstract:
Abstract We propose a data-driven 3D shape design method that can learn a generative model from a corpus of existing designs, and use this model to produce a wide range of new designs. The approach learns an encoding of the samples in the training corpus using an unsupervised variational autoencoder-decoder architecture, without the need for an explicit parametric representation of the original designs. To facilitate the generation of smooth final surfaces, we develop a 3D shape representation based on a distance transformation of the original 3D data, rather than using the commonly utilized binary voxel representation. Once established, the generator maps the latent space representations to the high-dimensional distance transformation fields, which are then automatically surfaced to produce 3D representations amenable to physics simulations or other objective function evaluation modules. We demonstrate our approach for the computational design of gliders that are optimized to attain prescribed performance scores. Our results show that when combined with genetic optimization, the proposed approach can generate a rich set of candidate concept designs that achieve prescribed functional goals, even when the original dataset has only a few or no solutions that achieve these goals.

Full text
Abstract:
Recent advances in visual sensing technology have gained much attention in the field of bridge inspection and management. Coupled with advanced robotic systems, state-of-the-art visual sensors can be used to obtain accurate documentation of bridges without the need for any special equipment or traffic closure. The captured visual sensor data can be post-processed to gather meaningful information for the bridge structures and hence to support bridge inspection and management. However, state-of-the-practice data postprocessing approaches require substantial manual operations, which can be time-consuming and expensive. The main objective of this study is to develop methods and algorithms to automate the post-processing of the visual sensor data towards the extraction of three main categories of information: 1) object information such as object identity, shapes, and spatial relationships - a novel heuristic-based method is proposed to automate the detection and recognition of main structural elements of steel girder bridges in both terrestrial and unmanned aerial vehicle (UAV)-based laser scanning data. Domain knowledge on the geometric and topological constraints of the structural elements is modeled and utilized as heuristics to guide the search as well as to reject erroneous detection results. 2) structural damage information, such as damage locations and quantities - to support the assessment of damage associated with small deformations, an advanced crack assessment method is proposed to enable automated detection and quantification of concrete cracks in critical structural elements based on UAV-based visual sensor data. In terms of damage associated with large deformations, based on the surface normal-based method proposed in Guldur et al. (2014), a new algorithm is developed to enhance the robustness of damage assessment for structural elements with curved surfaces. 3) three-dimensional volumetric models - the object information extracted from the laser scanning data is exploited to create a complete geometric representation for each structural element. In addition, mesh generation algorithms are developed to automatically convert the geometric representations into conformal all-hexahedron finite element meshes, which can be finally assembled to create a finite element model of the entire bridge. To validate the effectiveness of the developed methods and algorithms, several field data collections have been conducted to collect both the visual sensor data and the physical measurements from experimental specimens and in-service bridges. The data were collected using both terrestrial laser scanners combined with images, and laser scanners and cameras mounted to unmanned aerial vehicles.

The recent technological advancements have greatly improved the quality and resolution of displays. Yet, issues like full-color gamut representation and the long-lasting durability of the color emitters require further progression. Colloidal quantum dots manifest an inherent narrow spectral emission with optical stability, combined with various chemical processability options which will allow for their integration in display applications. Apart from their numerous advantages, they also present unique opportunities for the next technological leaps in the field.

Abstract:
On Thursday, 30 April 2020, the EdTech Hub participated in an “Ask me anything” session for policy-makers and funders in Nepal. The session focused on designing high-quality, effective, distance education programmes during the COVID-19 pandemic. Participants included high-level officials from the Nepalese government (e.g., the Ministry of Education, Science and Technology, the Curriculum Development Office and the Education Review Office), representatives from development partners (e.g., the World Bank, UNICEF and USAID) and other education organisations (e.g., OLE Nepal). The session was convened for two purposes. First, to consider international good practice and current trends in distance education during the COVID-19 pandemic, presented by the World Bank EduTech team and the EdTech Hub. Second, for the EdTech Hub team to gather questions from participants, to be able to target guidance specifically to the situation in Nepal. This document provides answers to a consolidated list of 10 questions received from stakeholders during the session. To consolidate any overlap, we have occasionally combined multiple questions into one. In other cases, where multiple important issues required a focused response, we split apart questions.
