Abstract:
Software modeling is an integral practice for software engineers, especially as the complexity of software solutions increases. Unified Modeling Language (UML) is the industry standard for software modeling. however, it is often used incorrectly and misunderstood by novice software designers. This study is centered around understanding patterns of student proficiency of abstraction and systems thinking within a software modeling context. The participants of this study (n = 97) belonged to a systems analysis and design course that is primarily taken by second-year university students. The exam solutions to a case study from the course were evaluated for modeling proficiency. As evidence of proficiency in abstract thinking and systems thinking, we evaluated UML activity diagrams, class diagrams, and sequence diagrams and the alignment between these representations in terms of functions, structures, and behaviors. The results suggest students being proficient in modeling the functional aspects of an information system while facing some difficulty in capturing the structural and behavioral aspects of an information system. Clustering analysis revealed two groups within the sample, with one group displaying a significantly higher abstraction and systems thinking ability. Statistically significant correlations were also found between student proficiency of abstraction and their modeling proficiency in terms of functions, structures, and behaviors.

Abstract:
In this work, a very efficient mixed-potential integral-equation formulation is implemented for the rigorous analysis of multilayered structures with arbitrarily shaped two-dimensional periodic metallic and/or dielectric inclusions. Original acceleration techniques have been developed for the computation of the components of the scalar and dyadic Green's functions, based on different types of asymptotic extractions according to the potential considered. The theoretical approach and its computational convenience have been validated through different full-wave analyses concerning both scattering problems and complex-mode dispersive behaviors in various frequency-selective structures for microwave applications.

Abstract:
The aim of this paper is to study the asymptotic behavior of a structure made of plates of thickness 2δ when δ → 0. This study is carried out within the frame of linear elasticity by using the unfolding method. It is based on several decompositions of displacements of the structure and on the passing to the limit in fixed domains.We begin by studying the displacements of a plate. We show that any displacement is the sum of an elementary displacement concerning the normal lines on the middle surface of the plate and a warping. An elementary displacement is linear with respect to the variable x3. It is written [Formula: see text] where [Formula: see text] is a displacement of the mid-surface of the plate. We show a priori estimates and convergence results when δ → 0. We characterize the limits of the unfolded displacements of a plate as well as the limits of the unfolded strained tensor.Then, we extend these results to structures made of plates. We show that any displacement of a structure is the sum of an elementary displacement of each plate and of a residual displacement. The elementary displacements of the structure (e.p.s.d.) coincide with elementary rod displacements in the junctions. Any e.p.s.d. is given by two functions belonging to H1( S ; ℝ3) where S is the skeleton of the structure (the set formed by the mid-surfaces of the plates constituting the surface). One of these functions, [Formula: see text], is the skeleton displacement. We show that [Formula: see text] is the sum of an extensional displacement and of an inextensional one. The first one characterizes the membrane displacements and the second one is a rigid displacement in the direction of the plates and it characterizes the flexion of the plates.Eventually, we pass to the limit as δ → 0 in the linearized elasticity system. On the one hand, we obtain a variational problem that is satisfied by the limit extensional displacement, and on the other hand, a variational problem satisfied by the limit of inextensional displacements.

Abstract:
A quay wall is a gravity wall structure having the dual functions of providing shore protection against light to moderate wave attack and a berthing face for ships. In the present study, nonlinear dynamic behavior of the quay walls is studied under the action of earthquake excitations by taking into account the soil-water-structure interaction. For this purpose, plane strain analysis of the wall is performed for both horizontal and vertical components of earthquake records; and the maximum displacements and stresses at critical points of the quay wall are obtained for different values of the wall slenderness ratio. From the numerical results, it is found that considering the vertical component of the ground motion besides the horizontal one in a linear analysis has a reduction effect on the quay wall seismic responses in comparison with that of the horizontal component alone. Moreover, it is found that nonlinear characteristics of soil, when the soil-water-structure interaction is taken into account, has more catastrophic effect on the performance of these walls in comparison with that of the linear one.

Abstract:
Background: Biological information drawn from eye-tracking metrics is providing evidence regarding drivers of cognitive decline in Alzheimer’s disease. In particular, pupil size has proved useful to investigate cognitive performance during online activities. Objective: To investigate the oculomotor correlates of impaired performance of patients with mild Alzheimer’s Clinical Syndrome (ACS) on a recently developed memory paradigm, namely the Short-Term Memory Binding Test (STMBT). Methods: We assessed a sample of eighteen healthy controls (HC) and eighteen patients with a diagnosis of mild ACS with the STMBT while we recorded their oculomotor behaviors using pupillometry and eye-tracking. Results: As expected, a group (healthy controls versus ACS) by condition (Unbound Colours versus Bound Colours) interaction was found whereby behavioral group differences were paramount in the Bound Colours condition. Healthy controls’ pupils dilated significantly more in the Bound Colours than in the Unbound Colours condition, a discrepancy not observed in ACS patients. Furthermore, ROC analysis revealed the abnormal pupil behaviors distinguished ACS patients from healthy controls with values of sensitivity and specify of 100%, thus outperforming both recognition scores and gaze duration. Conclusion: The biological correlates of Short-Term Memory Binding impairments appear to involve a network much wider than we have thought to date, which expands across cortical and subcortical structures. We discuss these findings focusing on their implications for our understanding of neurocognitive phenotypes in the preclinical stages of Alzheimer’s disease and potential development of cognitive biomarkers that can support ongoing initiatives to prevent dementia.

Abstract:
In this study, analytical method is applied for the estimation of dynamic behaviors of beam-coupled structures. Mathematical expressions are given with terms of shape factors, material information and assembly angles of each sub-component. Based on Euler-Bernoulli beam theory, entire formulation is built with compatibility of system dynamics. The coupled structures are divided into two types, point coupling and mass coupling, related with the properties of coupling points. Point coupling is commonly used assumption that two sub-components are combined with lumped spring or damping, and mass coupling has undeformable rigid joint which has mass and inertia like welded structures. Dynamic properties of coupled structures are predicted in forms of frequency response functions and spectral responses about given forces. The verification process is conducted for assessing the accuracy of the estimation formula by using modal frequencies and mode shapes of beam-coupled structures. Extracted modal parameters from experimental modal analysis and finite element method are adopted as reference values for verification.

Abstract:
To give rigorous mathematical proofs of chaotic behaviors in a given system, it is necessary to identify the homoclinic structures in the system. In this tutorial review, methods for constructing explicit solutions for nonlinear partial differential equations are presented, with more emphasis placed on those utilizing complete integrability associated with soliton equations. As an extended application, homoclinic orbits to spatial uniform plane waves of coupled modified nonlinear Schrödinger equations are obtained via the dressing method. During the procedure, it is necessary to introduce the Lax pair for these coupled equations, as well as its Floquet spectral analysis and corresponding Bloch functions.

Abstract:
In analysis and design of structures subjected to blast loading, equivalent Single-Degree-of-Freedom (SDOF) method is commonly recommended in design guides. In this paper, improved analysis method based on SDOF models is proposed. Both flexural and direct shear behaviors of structures subjected to blast load are studied using equivalent SDOF systems. Methods of deriving flexural and direct shear resistance functions are introduced, of which strain hardening and softening effects are considered. To collocate with the improved SDOF models, the improved design charts accounting for strain hardening and softening are developed through systematical analysis of SDOF systems. To demonstrate the effectiveness of the proposed analysis method, a model validation is made through comparing the predictions with laboratory shock tube testing results on reinforced concrete (RC) columns. It is found that compared to the conventional approach with elastic and elastic-perfectly-plastic model, the elastic-plastic-hardening model provides more accurate predictions. Additional non-dimensional design charts considering various levels of elastic-plastic-hardening/softening resistance functions are developed to supplement those available in the design guides with elastic-perfectly-plastic resistance function only, which provide engineers with options to choose more appropriate resistance functions in design analysis.

Abstract:
Numerous works have been recently carried out to describe friction and lubrication in the tool-sheet interface. This phenomenon is of great importance for all forming processes, particularly, in the deep drawing operations where the rapid progress in the field of computing requires the predictive knowledge of friction coefficient behaviors. The present paper considers the dynamical modeling by a global approach of the tangential force evolution. All measurements come from a tribometer equipped for strip-drawing tests on lubricated steel sheets and aluminum sheets, as a function of applied normal load. Models are obtained from serial, parallel, or closed-loop association structures for linear transfer functions. Numerical values of delays, time constants, and gain are identified for each test order; complexities and structures are determined with a double optimization. For all situations, a stop criterion is defined to achieve the optimal model, which is reached for the steel sheets.

Full text
Abstract:
A major challenge for Information Technology (IT) programs is that the rapid pace of evolution of computing technology leads to frequent redesign of IT courses. The problem is exacerbated by several factors. Firstly, the changing technology is the subject matter of the discipline and is also frequently used to support instruction; secondly, this discipline has only been formalized as a four-year university program within recent years and there is a lack of established textbooks and curriculum models; finally, updating courses is seldom rewarded in a higher education system that favors research and teaching for promotion and tenure. Thus, continuously updating their courses place a significant burden on the faculty. A case study approach was used to describe and explain the change processes in updating IT courses. Several faculty members at two institutions were interviewed and course changes were identified and analyzed. The analysis revealed a set of recurrent themes in change processes. An instructional design architecture approach also revealed a set of design domains representing the structure of the change processes. The design domains were analyzed in terms of the design decisions they represented, and also in terms of structures, functions and activities, which are related to Structures-Behaviors-Functions (SBF) analysis. The design domains model helped to explain both negative and positive outcomes that were observed in the data. When design efforts impact multiple domains the design is likely to be more difficult. Understanding the design domain architecture will assist future designers in this discipline.

Abstract:
There has been a continuous production of high quality reports focussing on fruitless as the genetic switch for male sexual behaviour in Drosophila melanogaster, and on fruitless’s contributions to creating a male-specific neural circuit within the CNS. However it has become increasingly clear that fruitless is not sufficient in itself to specify the full complement of male-specific behavioural repertoires. One obvious genetic candidate that contributes to the male neural circuit is doublesex. doublesex has long been known to be pivotal to the specification of the sexually dimorphic adult soma but it’s function in specifying sex-specific neural substrates has, up till now, been largely unexplored. While fruitless has so far shown to be found only in insects, doublesex is a more ancient gene and, as member of the Dmrt family of genes, is both structurally and functionally conserved throughout the animal kingdom. Thus the study of doublesex offers great potential for understanding the neuronal, developmental and physiological logic underlying innate and species-specific behaviours, in not one but both sexes, in organisms throughout the animal kingdom. Using the novel dsxGAL4 transgenic tool, generated by ends-in homologous recombination at the doublesex locus, I have been able to perform a systematic temporal and spatial survey of doublesex expression both within, and outwith, the nervous system. Excitingly, as doublesex is endogenously expressed in both males and females, this has uncovered profound dimorphic differences in male and female neural substrates. In the male this circuit is shared with fruitless (whose expression is restricted to adult males) and has allowed myself, and my colleagues in the Goodwin lab, through functional behavioural analyses, to gain greater understanding into how male-specific behavioural outputs may be generated. Further though, functional analyses impinging on the novel doublesex female circuitry has allowed us to gain new insight into the (largely unstudied) role that females play in the courtship ritual. The dsx GAL4 transgenic tool, and the insights gained in this study, are also of import in relation to dissecting out mechanisms involved in the post-mating physiological and behavioural changes the female undergoes after successful copulation with a male. As well as this, as doublesex is known to play a pivotal role in establishing the dimorphic morphology of the fly, this tool has begun to allow us an understanding of how the assembly of these dimorphic neural circuits is coordinated with the development, and maintenance, of a sex-specific anatomy and physiology to produce the complete male or female ‘state’; Integrating both mind (fly brain) and body (fly soma).

Abstract:
The Method of Moments (MoM) has been used extensively to solve electromagnetic problems. Its popularity is largely attributed to its adaptability to structures with various shapes and success in predicting the equivalent induced currents accurately. However, due to its dense matrix, especially for large structures, the MoM suffers from long matrix solution time and large storage requirement. In this thesis it is shown that use of wavelet basis functions result in a MoM matrix which is sparser than the one obtained by using traditional basis functions. A new wavelet system, different from the ones found in literature, is proposed. Stabilized Bi-Conjugate Gradient Method which is an iterative matrix solution method is utilized to solve the resulting sparse matrix equation. Both a one-dimensional problem with a microstrip line example and a two-dimensional problem with a rectangular patch antenna example are studied and the results are compared.

Full text
Abstract:
The interest in telecommuting stems from the potential benefits in alleviating traffic congestion, decreasing vehicle miles traveled (VMT), and improving air quality by reducing the necessity for travel between home and the workplace. Despite the potential economic, environmental, and social benefits, telecommuting has not been widely adopted, and there is little consensus on the actual impacts of telecommuting. One of the major hurdles is lack of a sound instrument to quantify the impacts of telecommuting on individuals’ travel behavior. As a result, the telecommuting phenomenon has not received proper attention in most transportation planning and investment decisions, if not completely ignored. This dissertation addresses the knowledge gap in telecommuting studies by examining several factors. First, it proposes a comprehensive outline to reveal and represent the complexity in telecommuting patterns. There are various types of telecommuting engagement, with different impacts on travel outcomes. It is necessary to identify and distinguish between those people for whom telecommuting involves a substitution of work travel and those for whom telecommuting is an ancillary activity. Secondly, it enhances the current modeling framework by supplementing the choice/frequency approach with daily telework dimensions, since the traditional approach fails to recognize the randomness of telecommuting engagement in a daily context. A multi-stage modeling structure is developed, which incorporates choice, frequency, engagement, and commute, as the fundamental dimensions of telecommuting activity. One pioneering perspective of this methodology is that it identifies non-regular telecommuters, who represent a significant share of daily telecommuters. Lastly, advanced statistical modeling techniques are employed to measure the actual impacts of each telecommuting arrangement on travelers’ daily activity-travel behavior, focusing on time-use analysis and work trip departure times. This research provides a systematic and sound instrument that advances the understanding of the benefits and potentials of telecommuting and impacts on travel outcomes. It is expected to facilitate policy and decision makers with higher accuracy and contribute to the better design and analysis of transportation investment decisions.

Abstract:
Le domaine du traitement de la géométrie suit un cheminement similaire à celui de l'analyse d'images avec l'explosion des publications consacrées à l'apprentissage profond ces dernières années. Un important effort de recherche est en cours pour reproduire les succès de l'apprentissage profond dans le domaine de la vision par ordinateur dans le contexte de l'analyse de formes 3D. Contrairement aux images, les formes 3D peuvent peuvent être représentées de différentes manières comme des maillages ou des nuages de points souvent dépourvus d'une structure canonique. Les algorithmes d'apprentissage profond traditionnels tels que les réseaux neuronaux convolutifs (CNN) ne sont donc pas faciles à appliquer aux formes 3D. Dans cette thèse, nous proposons trois contributions principales : premièrement, nous introduisons une méthode permettant de comparer des fonctions sur des domaines différents sans correspondances et de les déformer afin de rendre la topologie de leur ensemble de niveaux similaires. Nous appliquons notre méthode au problème classique de la correspondance de formes dans le contexte des applications fonctionnelles (functional maps) afin de produire des correspondances plus lisses et plus précises. Par ailleurs notre méthode reposant sur l'optimisation continue d'une énergie différentiable par rapport aux fonctions comparées elle est applicable à l'apprentissage profond. Nous apportons deux contributions directes à l'apprentissage profond des données 3D. Nous introduisons un nouvel opérateur de convolution sur des maillages triangulaires basés sur des coordonnées polaires locales et l'appliquons à l'apprentissage profond sur les maillages. Contrairement aux travaux précédents, notre opérateur prend en compte tous les choix de coordonnées polaires sans perte d'information directionnelle. Enfin, nous introduisons un nouveau module de convolution invariant par rotation sur les nuages de points et montrons que les CNN basés sur ce dernier peuvent surpasser l'état de l'art pour des tâches standard sur des ensembles de données non alignés même avec augmentation des données
The field of geometry processing is following a similar path as image analysis with the explosion of publications dedicated to deep learning in recent years. An important research effort is being made to reproduce the successes of deep learning 2D computer vision in the context of 3D shape analysis. Unlike images shapes comes in various representations like meshes or point clouds which often lack canonical structure. This makes traditional deep learning algorithms like Convolutional Neural Networks (CNN) non straightforward to apply to 3D data. In this thesis we propose three main contributions:First, we introduce a method to compare functions on different domains without correspondences and to deform them to make the topology of their set of levels more alike. We apply our method to the classical problem of shape matching in the context of functional maps to produce smoother and more accurate correspondences. Furthermore, our method is based on the continuous optimization of a differentiable energy with respect to the compared functions and is applicable to deep learning. We make two direct contributions to deep learning on 3D data. We introduce a new convolution operator over triangles meshes based on local polar coordinates and apply it to deep learning on meshes. Unlike previous works our operator takes all choices of polar coordinates into account without loss of directional information. Lastly we introduce a new rotation invariant convolution layer over point clouds and show that CNNs based on this layer can outperform state of the art methods in standard tasks on un-alligned datasets even with data augmentation

Abstract:
In the first part of the thesis, the 2-D structures in stratified media are analyzed using an efficient MoM technique. The method is used to optimize transmitted or reflected electric fields from the 2-D structures. The genetic algorithm is used in the optimization process. In the second part a 3-D MoM technique is implemented to analyze multilayered structures with periodically implanted material blocks. Using the method, the dispersion and reflection characteristics of the structure are calculated for different configurations. The results are compared with the results found in the literature and it is seen that they are in good agreement. Asymptotic Waveform Evaluation (AWE) technique is utilized to obtain the Pade approximation of the solution in terms of frequency. The high order derivatives that are required by the AWE technique are calculated through Automatic Differentiation technique. Using the AWE method, the dispersion diagram and reflection characteristics of the periodic structures are obtained in a shorter time. The results are compared with the ones obtained through direct calculation and it is seen that they are in perfect agreement. The reflection coefficients that are obtained from the 3-D MoM procedure are used to calculate Green&rsquo
s functions that approximate electric field of an infinitesimal dipole on the periodically implanted substrate. Using the calculated Green&rsquo
s functions and the spectral domain MoM procedure, dispersion characteristics of a microstrip line on the periodically implanted substrate are obtained.

Abstract:
AbstractSynthetic biologists use and combine diverse biological parts to build systems such as genetic circuits that perform desirable functions in, for example, biomedical or industrial applications. Computer-aided design methods have been developed to help choose appropriate network structures and biological parts for a given design objective. However, they almost always model the behavior of the network in an average cell, despite pervasive cell-to-cell variability. Here, we present a computational framework to guide the design of synthetic biological circuits while accounting for cell-to-cell variability explicitly. Our design method integrates a NonLinear Mixed-Effect (NLME) framework into an existing algorithm for design based on ordinary differential equation (ODE) models. The analysis of a recently developed transcriptional controller demonstrates first insights into design guidelines when trying to achieve reliable performance under cell-to-cell variability. We anticipate that our method not only facilitates the rational design of synthetic networks under cell-to-cell variability, but also enables novel applications by supporting design objectives that specify the desired behavior of cell populations.

Abstract:
This paper presents a Hilbert-Huang transform based signal reconstruction technique for the modal analysis of structural systems using vibration measurements. The original measured signal is initially undergone a well defined band-pass filter in order to solve the mode confounding problem. After the data preprocessing, each mode of the signal is reconstructed via the proper selection of intrinsic mode functions (IMFs) that are derived from the empirical mode decomposition of the signal’s mode. Through the signal reconstruction mode by mode, the structural parameter such as natural frequency is accurately evaluated, whose accuracy depends on the criterion for selecting the IMFs using the developed component sifting process. Reliable evaluation of systems’ characteristics leads to accurate prediction of systems’ behaviors for structural safety purpose. In this study, data preprocessing is operated to alleviate the problems of mode mixing and noise contaminated signal, as well as to compare with the previous work.

Abstract:
This paper presents a novel approach to deal with the analysis of composite aerospace structures with curved sections. The Carrera Unified Formulation is exploited to create hierarchical high-order beam models capable of detecting both local and global mechanical behaviors of composite structures. The blending function method is applied to introduce the exact shape of the cross-section boundaries into the mapping functions. Problems at both microstructure scale (fiber-matrix system) and macrostructure scale (whole components) can be studied with no lack of generalization. Several numerical examples of aerospace structures are included and the results are compared against those from the literature, as well as solid solutions obtained through the commercial software MSC Nastran. From this study, it is clear than the present formulation has demonstrated to be a powerful tool for the study of composite structures, enabling to obtain complex 3D-like solutions with a substantial reduction in the computational costs.

Abstract:
Rapid deployment of marine structures is of growing importance to U.S. naval forces. Surface-based inflatable structures including Rigid Inflatable Boats (RIBs), inflatable causeways and bridging, and launch and recovery systems provide unique solutions for temporary structures during sea-based missions. When performance specifications demand minimal weight and stowage, rapid deployability and temporary rigidity, solutions are limited to inflatable structures constructed of flexible materials. Driven by air pressure, today’s inflatables provide significant load-carrying capacities per unit weight (or stowed volume) utilizing technical textiles, elastomers or “soft” composites. Overloading of inflatable structures produces unique fail-safe behaviors (reversible wrinkling) that allow the structures to assume rigidity and load-carrying capacity upon load removal. Design standards are virtually nonexistent for inflatable structures involving shapes constructed of spheres, beams, arches and most recently flat panels using 3D woven drop-stitch panels. Predictive performance tools (analytical and numerical) for static applications lag significantly behind those for conventional structures. Nonlinear system behaviors (material and geometric), thermo-mechanical coupling and fluid-structure interactions (FSI’s) pose significant challenges when applying existing design tools to inflatable structures. This gap is further exacerbated for dynamic applications as inflatable structures exhibit pressure-dependent natural frequencies and mode shapes. Surface-based structures must be designed with consideration given to operational sea state frequencies and wave periods so that the onset of structural instabilities (wrinkling, buckling) and loss of load-carrying capacities can be prevented. The present research establishes the validity of physics based models using the Ideal Gas Law as an equation of state (EOS) to predict the natural frequencies and corresponding mode shapes of air-inflated drop-stitch fabric panels as functions of inflation pressure. Particular concern is given to the breathing modes for inflation pressures ranging from 5.0 to 30.0 psig. The presence of breathing modes can negatively impact the riding performance of RIBs vessels constructed with drop-stitch fabric hulls by amplification of the panel’s skin separation displacements and vertical accelerations, and are not seen in this material system for the pressures considered. Both numerical and experimental methods are pursued; the results of laboratory modal experiments are used to validate the numerical models. Predicted and experimental natural frequencies and mode shapes are compared and excellent correlation was observed. Increasing inflation pressures produced increasing in-plane and through-thickness normal stresses and modal frequencies of the drop-stitch fabric panels.

Abstract:
A finite element method has been developed for modeling the characteristics of self-pierced rivets (SPR) in the aluminum parts and structures subjected to impact. It considers SPR elastic, inelastic and separation behaviors and was developed based on the coupon test results in lap shear, coach peel, and tension modes. The method consists of establishing baseline strength characteristics in the six degrees of freedom; and then modifying the baseline properties with coefficient factors (Ki) factors that influence the performance of SPR (thickness, differences in material, temperature, impact velocity, size of connection). The resulting combination is a material damage function that is utilized as the material properties of beam-type spring elements simulating the SPR connection in a FE model. The baseline properties and the equations for coefficient factors (Ki) developed in this study are provided. The material damage functions were developed in the RADIOSS environment, but can be applied to other codes as well. The method was validated at the component level using various configuration of a hat section tube. The CAE prediction using the new method correlates with the test results well in all the cases.

Abstract:
Abstract Impact interactions can excite complex nonlinear resonant responses in structures subjected to simple periodic excitation. The specific features of these resonances are concentration of high harmonics in corresponding waveforms, dependence of their behaviour on parameters and initial conditions, synergistic spatial effects, and generation of essential forces and stresses. An effective approach to analysis of these resonances was developed using special functions, called periodic Green functions. An introduction of these functions allows the regular study of resonant phenomena in vibro-impact systems based on structural presentations and without reference to differential equations of motion. The paper reviews some results on the application of periodic Green functions for analysis of resonant phenomena in vibro-impact structures with lumped and distributed parameters. The physical experiments support the results of analysis.

Full text
Abstract:
In a truly multiscale analysis of multilayered composites, the underlying phenomena are represented and their effect on the overall behavior is determined considering the interaction between the different phases and between the laminas. The analysis gets more involved when multiple phenomena are considered since in this case not only the direct effects play a role but also the coupled effects contribute to the distribution of the local fields and the overall response. In a fibrous composite laminate reinforced with piezoelectric filaments, for example, passing an electric field in the fibers generates stresses and strains which propagate through the composite medium due to constraints that exist both at the micromechanical, ply level, and the macromechanical, laminate level. Pyroelectricity is another coupling phenomenon in which a temperature change is caused by an electric field, and hence leads to changes in the stress and strain fields throughout the composite medium. The above phenomena have been considered by the authors in a unified, transformation field analysis (TFA) approach in which stresses and strains which cannot be removed by mechanical unloading are treated as transformation fields. Due to mutual constraints of the phases and the bonded plies, local transformations generate stresses at the micro and macro levels, which are computed by means of influence functions which depend on material geometry and properties. Treatment of damage follows the same scheme but the transformation fields are instead determined such that the local stresses in the affected phase are removed. In the present paper, implementation of the TFA approach in a general purpose finite element code is described. This expands the multiscale analysis outlined above to composite structures where complex geometries can be modeled and the effect of local phenomena can be considered. This naturally comes at a much larger cost of the computations compared to finite element analysis with homogenized models but the benefit of obtaining a more realistic response is clear. Moreover, the availability of high performance computing and parallel processing overcomes the computation time barrier. In the present paper however, simple examples of laminated structures are given as proof of concept in which the results are compared to those of standalone routines. Since the TFA approach centers on treating the composite medium as elastic with induced local transformations, implementation in the finite element framework does not require generation of an overall instantaneous stiffness matrix, which saves tremendously on the computation time. Instead, overall transformation strains, or stresses, are computed through a multiscale model, which is implemented as a user routine, and treated in the general finite element solution as nonmechanical strains in the same way thermal strains are treated.

Abstract:
External forces, cell adhesion and soluble signaling molecules influence fundamental functions of cells like shape, migration, proliferation or differentiation. Thus, investigating how mechanical forces affect 3D cell structure and function is of crucial significance in order to gain a better understanding healthy and malignant cell behavior during embryogenesis, regeneration or malignancy [1]. Micromanipulation of cells in a controlled environment is a widely used approach for understanding cellular responses with respect to external mechanical forces. While experimental data provide optical information about the overall cell shape, the 3D deformation state of intracellular structures is not accessible by direct observations and measurements. However, the continuous description of the intracellular deformation state can be calculated as a numerical solution of the boundary value problem given by the partial differential equations of structural mechanics, including a set of canonic material constants (stiffness, compressibility), and the boundary conditions derived from time series of images, e.g. change of visible cell contours. The main idea of our approach is to reformulate the problem of finding optimal modeling parameters as an image registration problem. That is the optimal set of modeling parameters corresponds to the minimum of a suitable similarity measure between computationally predicted and experimentally observed deformations. In this article, we focus on the numerical analysis of uniaxial stretching of a rat embryonic fibroblast 52 (REF 52) based on a series of 2D images reflecting the successive alteration of cell contours during deformation. The goal of this study consists in finding an optimal set of material constants within a non-linear hyperelastic material law, which is able to reproduce results of experimental observations.

Abstract:
Abstract Yield stresses, allowable stresses, moment capacities (plastic moments), external loadings, manufacturing errors are not given fixed quantities in practice, but have to be modelled as random variables with a certain joint probability distribution. Hence, problems from limit (collapse) load analysis or plastic analysis and from plastic and elastic design of structures are treated in the framework of stochastic optimization. Using especially reliability-oriented optimization methods, the behavioral constraints are quantified by means of the corresponding probability ps of survival. Lower bounds for ps are obtained by selecting certain redundants in the vector of internal forces; moreover, upper bounds for ps are constructed by considering a pair of dual linear pro-prams for the optimizational representation of the yield or safety conditions. Whereas ps can be computed e.g. by sampling methods or by asymptotic expansion techniques based on Laplace integral representations of certain multiple integrals, efficient techniques for the computation of the sensitivities (of various orders) of ps with respect to input or design variables have yet to be developed. Hence several new techniques are suggested for the numerical computation of derivatives of ps.

Abstract:
A new LaSMP smart material exhibits shape memory behaviors and stiffness variation via UV light exposures. This dynamic stiffness provides a new noncontact actuation mechanism for engineering structures. Isogeometric analysis utilizes high order and high continuity NURBS as basis functions which naturally fulfills C1-continuity requirement of Euler-Bernoulli beam and Kirchhoff plate theories. The UV light-activated frequency control of LaSMP laminated beam and plate structures based on the isogeometric analysis is presented in this study. The accuracy and efficiency of the proposed isogeometric approach are demonstrated via several numerical examples in frequency control. The results show that, with LaSMPs, broadband frequency control of beam and plate structures can be realized. Furthermore, the length of LaSMP patches on beams is varied, which further broadens its frequency variation ranges. Studies suggest that 1) the newly developed IGA is an effective numerical tool and 2) the maximum frequency change ratio of beam and plate structures respectively reach 24.30% and 6.37%, which demonstrates the feasibility of LaSMPs induced vibration control of structures.

Abstract:
A novel approach for the analysis of the non-linear behavior of bio-structures is presented here. This method is developed in the framework of the Carrera Unified Formulation (CUF), a higher-order 1D theory according to which the kinematics of the problem depends on the arbitrary expansion of the generalized unknowns. Taylor-like (TE) and Lagrange-like expansion functions (LE) are employed to describe the kinematic field along the cross-section and, the finite element method (FEM) is used to formulate the governing equations. In this work, the effects of material nonlinearities are investigated and, the problem is solved by using the Newton-Raphson method. An atherosclerotic plaque of an artery is introduced as a typical bio-structure with complex geometry and studied for both linear and non-linear material cases. The results from the proposed technique highlight the accuracy of the in-plane and out-of-plane stress/strain distributions for different 1D models. The 3D-like accuracy of local effect predictions, the possibility of dealing with complex geometries, and low computational costs of nonlinear analyses make the present formulation appealing for biomechanical applications.

Full text
Abstract:
The research is devoted to the study of the phenomenon of mediatization of art on the example of virtual museums. Main objective of the study is to give communication characteristics of the mediatized socio-cultural institutions. The subject of the research is forms, directions and communication features of virtual museums. Methodology. In the process of study, the method of communication analysis, which allowed to identify and characterize the main factors of the museum’s functioning as a communication system, was used. Among them, special emphasis is put on receptive and metalinguistic functions. Results / findings and conclusions. The need to be competitive in the information space determines the gradual transformation of socio-cultural institutions into mass media, which is reflected in the content and forms of dialogue with recipients. When cultural institutions begin to function as media, they take on the features of media structures that create a communication environment localized by the functions of communicators and audience expectations. Museums function in such a way that along with the real art space they form a virtual space, which puts the recipients into the reality of the exhibitions based on the principle of immersion. Mediaization of art on the example of virtual museum institutions allows us to talk about: expanding of the perceptual capabilities of the audience; improvement of the exposition function of mediatized museums with the help of Internet technologies; interactivity of museum expositions; providing broad contextual background knowledge necessary for a deep understanding of the content of works of art; the possibility to have a delayed viewing of works of art; absence of thematic, time and space restrictions; possibility of communication between visitors; a huge target audience. Significance. The study of the mediatized forms of communication between museums and visitors as well as the directions of their transformation into media are certainly of interest to the scientific field of “Social Communications”.

CAPACITY EVALUATION OF EIGHT BOLT EXTENDED ENDPLATE MOMENT CONNECTIONS SUBJECTED TO COLUMN REMOVAL SCENARIO. The Hong Kong Institute of Steel Construction, September 2021. http://dx.doi.org/10.18057/ijasc.2021.17.3.6.

Full text
Abstract:
The extended stiffened endplate (8ES) connection is broadly used in the seismic load-resisting parts of steel structures. This connection is prequalified based on the AISC 358 standard, especially for seismic regions. To study this connection’s behaviors, in the event of accidental loss of a column, the finite element model results were verified against the available experimental data. A parametric study using the finite element method was then carried out to investigate these numerical models’ maximum capacity and effective parameters' effect on their maximum capacity in a column loss scenario. This parametric analysis demonstrated that these connections fail at the large displacement due to the catenary action mode at the rib stiffener's vicinity. The carrying capacity, PEEQ, Von-Mises stress, middle column force-displacement, critical bolt axial load, and the beam axial load curves were discussed. Finally, using the Least Square Method (LSM), a formula is presented to determine the displacement at the maximum capacity of these connections. This formula can be used in this study's presented method to determine the maximum load capacity of the 8ES connections in a column loss scenario.
