We offer an alternate derivation for the symmetric-hyperbolic formulation of the equations of motion for a hyperelastic material with polyconvex stored energy. The derivation makes it clear that the expanded system is equivalent, for weak solutions, to the original system. We consider motions with variable as well as constant temperature. In addition, we present equivalent Eulerian equations of motion, which are also symmetric-hyperbolic.

Stop-motion animation is an ancient form of animation. After nearly a century of development, the material application of stop-motion animation becomes diversified. Currently, however, the well-known stop-motion animations are produced by clay materials. Clay materials play an important role in the application of stop-motion animation. Clay materials, because of its expressive ability demonstrated by its strong plasticity, enables the roles it has shaped lively and characteristic and the stop-motion animation to be full of affinity and vitality. This paper starts from the properties and material expressive ability of clay materials, combined with the short clay animation film named Daffodil to have a study and analysis of the vitality demonstrated by clay materials.

The kinematics of the deep rolling tool, contact stress, and induced residual stress in the near-surface material of a flat Ti-6Al-4V alloy plate are numerically investigated. The deep rolling tool is under multiaxis nonlinear motion in the process. Unlike available deep rolling simulations in the open literature, the roller motion investigated in this study includes penetrative and slightly translational motions. A three-dimensional finite element model with dynamic explicit technique is developed to simulate the instantaneous complex roller motions during the deep rolling process. The initial motion of the rollers followed by the penetration motion to apply the load and perform the deep rolling process, the load releasing, and material recovery steps is sequentially simulated. This model is able to capture the transient characteristics of the kinematics on the roller and contacts between the roller and the plate due to variations of roller motion. The predictions show that the magnitude of roller reaction force in the penetration direction starts to decrease with time when the roller motion changes to the deep rolling step and the residual stress distributions in the near-surface material after the material recovery step varies considerably along the roller path.

In order to get a profound understanding of planet motion and orbital motion in CCOS (Computer Controlled Optical Surfacing), a compare study between them was conducted here. The material removals of two motions under the same conditions were simulated and the removal of planet motion was higher than that of orbital motion. The figuring abilities of two motions were also studied through the theory of cut-off frequency and the result showed that planet motion had a higher cut-off frequency. Then two figuring runs which employ the planet motion and the orbital motion were simulated. The convergence rates and polishing times of these two runs were compared and the result showed that planet motion had a higher figuring efficiency. As planet motion has stronger figuring ability and higher figuring efficiency, it’s better to employ planet motion in CCOS to get higher convergence rate and higher accuracy when fabricating high quality mirrors.

Solid objects lying on slopes for which gravity alone would be insufficient to overcome frictional resistance have long been known to experience downslope motions when subject to alternations in temperature. This paper will suggest that similar motions are possible in situations where gravity is either absent or even working against the prospective motions. It will be argued that the effects of differential material properties when the solid is subject to alternations of tension and compression, accompanying periodic cycles of high and low temperatures, can also produce motion. While most of the illustrative examples will be chosen from certain movements of either ice and ice-rich materials or asphalt pavements, it would appear that similar behaviour could be experienced by much wider classes of materials. It is suggested that this form of thermal ratchet process could be of importance far wider than is currently recognized.

Human motion collected in real-world environments without instruction from researchers - or natural motion - is an understudied area of the field of motion capture that could increase the efficacy of assistive devices such as exoskeletons, robotics, and prosthetics. With this goal in mind, a natural motion dataset is presented in this thesis alongside algorithms for analyzing human motion. The dataset contains more than 36 hours of inertial motion capture data collected while the 16 participants went about their lives. The participants were not instructed on what actions to perform and interacted freely with real-world environments such as a home improvement store and a college campus. We apply our dataset in two experiments. The first is a study into how manual material handlers lift and bend at work, and what postures they tend to use and why. Workers rarely used symmetric squats and infrequently used symmetric stoops typically studied in lab settings. Instead, they used a variety of different postures that have not been well-characterized such as one-legged lifting and split-legged lifting. The second experiment is a study of how to infer human motion using limited information. We present methods for inferring human motion from sparse sensors using Transformers and Seq2Seq models. We found that Transformers perform better than Seq2Seq models in producing upper-body and full-body motion, but that each model can accurately infer human motion for a variety of postures like sitting, standing, kneeling, and bending given sparse sensor data.
Master of Science
To better design technology that can assist people in their daily lives, it is necessary to better understand how people move and act in the real-world with little to no instruction from researchers. Personal assistants such as Alexa and Google Assistant have benefited from what researchers call natural language processing. Similarly, natural motion processing will be useful for everyday assistive devices like prosthetics and exoskeletons. Unscripted human motion in real-world environments - or natural motion - has been made possible with recent advancements in motion capture technology. In this thesis, we present data from 16 participants who wore a suit that captures accurate human motion. The dataset contains more than 36 hours of unscripted human motion data in real-world environments that is usable by other researchers to develop technology and advance our understanding of human motion. In addition, we perform two experiments in this thesis. The first is a study into how manual material handlers lift and bend at work, and what postures they tend to use and why. The second is a study into how we can determine what a person's body is doing with a limited amount of information from only a few sensors. This study could be useful for making commercial devices like smartphones, smartwatches, and smartglasses more valuable and useful.

We present a framework for predicting the physical properties of moving deformable objects observed in video. We apply our framework to analyze videos of fabrics moving under various unknown wind forces, and recover two key material properties of the fabric: stiffness and mass. We extend features previously developed to compactly represent static image textures to describe video textures such as fabric motion. A discriminatively trained regression model is then used to predict the physical properties of fabric from these features. The success of our model is demonstrated on a new database of fabric videos with corresponding measured ground truth material properties that we have collected. We show that our predictions are well correlated with both measured material properties and human perception of material properties. Our contributions include: (a) a method for predicting the material properties of fabric from a video, (b) a database that can be used for training and testing algorithms for predicting fabric properties containing RGB and RGBD videos of real videos with associated material properties and rendered videos of simulated fabric with associated model parameters, and (c) a perceptual study of humans' ability to estimate the material properties of fabric from videos and images.

The natural degradation of processed black and white cellulose acetate based 35mm motion picture film material has been investigated using 1H and 13C NMR spectroscopy. According to current standards only this material is considered to be an archival recording medium. It has been recognised that understanding the relationship between structure and physical properties would provide knowledge to help inhibit motion picture film degradation. A correlation between observed changes in molecular structure and physical property changes namely, % moisture regain, acidity and viscosity has been obtained. Results of these studies indicate that the primary mode of degradation is hydrolysis of ester groups leading to deacetylation of the C6 acetyl group in the polymer chain. On further deactylation, the C3 acetyl group is lost in preference to the C2 acetyl group. Therefore, it can be concluded that a decrease in viscosity retention and an increase in acidity concurs with deacetylation of the polymer chain. On this basis mechanisms of deacetylation would predominate since oxidative chain-scission would take place through the C2 acetyl group which is less accessible. NMR spectroscopy also reveals that the plasticisers, namely triphenyl phosphate and diethyl phthalate incorporated into cellulose acetate base, influence its stability. Under archival conditions the triphenyl phosphate plasticiser appears not to undergo degradation but becomes increasingly incompatible with the cellulose acetate base. Diethyl phthalate however was seen to degrade as the cellulose acetate base itself degrades. A more detailed understanding of the macromolecular structure of cellulose acetate based motion picture film has been obtained with the use of Molecular Modelling and Graphics studies using QUANTA software. This supports the NMR study indicating that the C6 and C3 acetyl groups are clearly more exposed in the polymer matrix and therefore, are more likely to be lost as hydrolysis of the polymer chain occurs. Modelling studies also supported reduced stability of the polymer in the presence of plasticisers. When plasticisers were docked within the polymer matrix distortions of the polymers chains were observed as chains were pushed apart and dihedral angles altered. The role of the emulsion in film degradation was also examined by electrophoresis. This separation of proteins has shown that under archival conditions, naturally aged gelatin emulsion layers show a decrease in molecular weight. This has been attributed to the acid catalysed deacetylation of the cellulose acetate base lowering the pH of the film and inducing hydrolysis of gelatin. Only when considerable amounts of acid have been evolved are changes to the emulsion observed. Finally, the effects of storage containers were characterised using viscosity and acidity measurements. Accelerated ageing studies at 50%RH 70°C to emulate archival storage conditions revealed that in the early stages of degradation polyethylene and polypropylene cans were more detrimental to film stability than the more traditional metal can. The plastic cans were shown to promote oxidative degradation of the film and polypropylene was shown to lead to higher levels of peroxide in films than polyethylene

The thesis presents a framework for Non-Line-of-Sight Computer Vision techniques using wave fronts. Using short-pulse illumination and a high speed time-of-flight camera, we propose algorithms that use multi path light transport analysis to explore the environments beyond line of sight. What is moving around the corner interests everyone including a driver taking a turn, a surgeon performing laparoscopy and a soldier entering enemy base. State of the art techniques that do range imaging are limited by (i) inability to handle multiple diffused bounces [LIDAR] (ii) Wavelength dependent resolution limits [RADAR] and (iii) inability to map real life objects [Diffused Optical Tomography]. This work presents a framework for (a) Imaging the changing Space-time-impulse-responses of moving objects to pulsed illumination (b) Tracking motion along with absolute positions of these hidden objects and (c) recognizing their default properties like material and size and reflectance. We capture gated space-time impulse responses of the scene and their time differentials allow us to gauge absolute positions of moving objects with knowledge of only relative times of arrival (as absolute times are hard to synchronize at femto second intervals). Since we record responses at very short time intervals we collect multiple readings from different points of illumination and thus capturing multi-perspective responses allowing us to estimate reflectance properties. Using this, we categorize and give parametric models of the materials around corner. We hope this work inspires further exploration of NLOS computer vision techniques.

On the 4th of October 1562, the Polish princess Catherine Jagiellon married the Swedish prince and duke of Finland Johan Vasa. Leaving Poland, Catherine Jagiellon was equipped with a very rich dowry and followed by an entourage of nearly 50 people. The objective of this study is to investigate the objects and people surrounding the newly wedded 16th century princess and asses if the document mirrors the complex cultural interactions of the early modern world. The analysis of the inventory is carried out using two theoretical approaches: material culture and culture transfer. The study is constructed in two parts. The first part focuses on the analysis of the sections of the inventory following the order of the document. If possible, the objects are mapped, their history is traced through the sources, their appearance and function are discussed. The examination of the members of the court is also carried out. With the deepened analysis of the inventory as a basis, the second part of the study is dedicated to the search of culture hybridization markers in described artefacts, people, practices as well as the language of the document itself. With the result of this investigation, the author is able to pinpoint the complex international cultural processes that were occurring in an early modern world.

Résumé: Cette recherche, prenant comme référentiel théorique l¿Analyse du discours de la ligne matérialiste, avec le film Dieu est Brésilien s¿est proposée à apporter à la pratique analytique la matérialité du cinéma, en prenant comme approche les scènes dans lesquelles l¿accord entre les interventions divines et les changements filmiques sont traversés par le silence. Dans ces extraits de l¿intrigue, Dieu entre en contact direct avec les humains, produisant des interventions de différents ordres. Les changements filmiques marqués sont caractérisés par caméra lente ou rapide, introduction d¿effet visuel et sonore, suppression dês bruits et remplissage de l¿espace sonore avec de la musique. Cependant, deux diferentes relations de sens sont distingées dans le corpus: d¿un côté par des démonstrations de puissance divine face à l¿insolence des mortels Taoca et Quinca das Mulas, un effet disjonctif est là produit; d¿un autre côté, les interventions pacifiques et humanisées de Dieu dans lês scènes avec la jeune femme Madá produisent un effet conjonctif. Dans les deux groupes de relations certains sens ne sont formulées pas, ce qui se marque à la surface textuelle sous la forme de suspension de l¿interlocution des personnages. De sorte que la nature du silence dans l¿ensemble de scènes soit comprise, il a été nécessaire de renvoyer les formulations ¿ comprenant les images, les gestes, la musique, lês bruits, les mots ¿ aux interdiscours ou mémoire discursive. Ce travail a montré des déplacements de sens dans la position du devin dans la formation discursive religieuse
Resumo: Esta pesquisa, tomando como referencial teórico a Análise de Discurso de linha materialista, com o filme Deus é Brasileiro se dispôs a trazer para a prática analítica a materialidade do cinema, tendo como enfoque cenas nas quais é regular a concomitância entre intervenções divinas e alterações fílmicas atravessadas de silenciamentos. Nesses trechos do enredo, Deus entra em contato direto com os humanos, produzindo intervenções de diferentes ordens. As alterações fílmicas aí marcadas se caracterizam por câmera rápida ou lenta, introdução de efeitos visuais e sonoros, supressão de ruídos e preenchimento do espaço sonoro por música. No entanto, distinguem-se no corpus dois recortes, definidos segundo diferentes relações de sentidos inscritas nas cenas: de um lado, com as demonstrações do poder divino diante da insolência dos mortais Taoca e Quinca das Mulas, produz-se um efeito disjuntivo; de outro, as intervenções pacíficas e humanizadas de Deus nas cenas com a moça Madá produzem um efeito conjuntivo. Em ambos os recortes certos sentidos são silenciados, o que se marca na superfície textual sob a forma da suspensão da interlocução dos personagens. Para que se compreendesse a natureza do processo de silenciamento no conjunto de cenas foi preciso remeter as formulações ¿ incluindo as imagens, os gestos, a música, os sons, as palavras ¿ ao interdiscurso ou memória discursiva. Este trabalho mostrou deslizes de sentidos na posição do divino na formação discursiva religiosa

Syntactic foam, specifically a host urethane embedded with hollow microspheres, has been shown to be an effective method to treat pressure pulsations, also known as noise, within a hydraulic system; however, the current generation of foam becomes less effective with increasing system pressure, particularly ineffective above 7 MPa. Material modeling predicts that increasing the initial internal pressure of a microsphere will allow voids within the foam to retain their size at pressures up to 35 MPa and the foam will remain compliant at those pressures. Noise is attenuated by an expansion chamber lined with syntactic foam when the system pressure causes embedded microspheres to collapse, which leaves a gaseous void within the host urethane, greatly reducing the effective bulk modulus of the foam. Predicted material properties are then used in conjunction with a previously developed linear acoustic model to predict the effectiveness of developmental syntactic foams. Changing the mechanical properties of the current host urethane does not have a drastic impact on the overall performance unless the properties have been reduced to the approximate order as the properties of the void. The factors with the most consequence on noise control effectiveness are the internal pressure of the microspheres and system pressure.

Simulation of a single flexible fiber suspension solved using partitioned fluid structure interaction (FSI) strategy is presented in this paper. The study of fiber motion during injection modeling process in composite material manufacturing is the motivation of this research. Fluid field is solved by mixed finite element method (FEM). Stokes equation is used as governing equation due to low Reynolds number characteristics. Total Lagrangian (TL) incremental FEM is used for calculating flexible fiber translation, rotation and deformation. Bathe time integration method is used for solving fiber dynamics. The interaction between the fiber (solid) and fluid results from forces on the surface of fiber, which are extracted from fluid solver and are exerted on fiber, solved as the natural boundary condition. After solid solver running forward a certain time step, new positions and velocities of each node on fiber surface are obtained which can be used for updating fluid mesh domain and served as essential boundary condition of fluid field. The process continues until the motion and deformation of fiber are obtained. Example of rigid and flexible fiber motion in a simple shear flow and a Poiseuille flow are presented in this paper. The simulation of rigid fiber are very close to the result of Jeffery’s theory. Snake rotation can be observed when the flexible fiber was tested in Poiseuille flow.

We study the solid waste stream in a rotary kiln with L/D ≥ 10 in this paper. The particle trace is determined based upon the vector force analysis on it, and therefore, the distance and time of single particle motion in a circle are deduced. Using filling method, the mean distance and the mean residence time of material flow are then calculated, in which the motion results from the material beyond the critical angle of motion θ falling because of the kiln’s rotation. The influence of the filling angle of particles on the axial velocity is also analyzed. At the same time some experiments on different solid waste streams in the rotary kiln are carried on so that the equation of flow derived by theoretical analysis is modified according to the experimental results. Industrial analysis is done on several typical kinds of solid waste from two paper plants. Moreover, on a small scale rotary burning device, we conducted hot test on the solid waste from the paper plants to study the dependence of burnout rate on the residence time and the temperature inside the kiln. The results indicate that the water content and volatile content are high in the solid waste from paper plants. Hence, to ensure the high burnout rate, the solid waste has to stay in a rotary kiln for a long enough residence time at high temperature, which requires, in turn, that the rotary velocity of a rotary kiln be lower than 10 rpm, the inclination angle less than 2°, and the temperature inside higher than 800 °C. In addition, we conducted hot test on typical municipal residential waste in South China, from which we come to the conclusion that without enough air supply, clinker and slag are formed when the inside temperature is 850 °C.

In the early days, there were significant limitations to the build size of laser powder bed fusion (L-PBF) additive manufacturing (AM) machines. However, machine builders have addressed that drawback by introducing larger L-PBF machines with expansive build volumes. As these machines grow, their size capability approaches that of directed energy deposition (DED) machines. Concurrently, DED machines have gained additional axes of motion which enable increasingly complex part geometries—resulting in near-overlap in capabilities at the large end of the L-PBF build size. Additionally, competing technologies, such as binder jet AM and metal material extrusion, have also increased in capability, albeit with different starting points. As a result, the lines of demarcation between different processes are becoming blurred. Internal Boundaries of Metal Additive Manufacturing: Future Process Selection examines the overlap between three prominent powder-based technologies and outlines an approach that a product team can follow to determine the most appropriate process for current and future applications.

The paper deals with the urgent problem of application of virtual reality in foreign language training. Statistical data confirms that the number of smartphone users, Internet users, including wireless Internet users, has been increasing for recent years in Ukraine and tends to grow. The coherence of quick mobile Internet access and presence of supplementary equipment enables to get trained or to self-dependently advance due to usage of virtual reality possibilities for education in the stationary classrooms, at home and in motion. Several important features of virtual reality, its advantages for education are discussed. It is noted that virtual reality is remaining a relatively new technology in language learning. Benefits from virtual reality implementation into foreign language learning and teaching are given. The aspects of immersion and gamification in foreign language learning are considered. It is emphasized that virtual reality creates necessary preconditions for motivation increasing. The results of the survey at two higher education institution as to personal experience in using VR applications for learning foreign languages are presented. Most students at both universities have indicated quite a low virtual reality application usage. Six popular virtual reality applications for foreign language learning (Mondly, VRSpeech, VR Learn English, Gold Lotus, AltSpaceVR and VirtualSpeech) are analyzed. It is stated that the most preferred VR application for foreign language learning includes detailed virtual environment for maximal immersion, high- level visual effects similar to video games, simple avatar control, thorough material selection and complete complicity level accordance of every element and aspect, affordability, helpful and unobtrusive following up.
