Abstract:
In order to assess the inherent damage mechanism of reinforced concrete (RC) structures, a micro-macro simulation technique combined with multilevel damage assessment methodology is presented. An element-coupling model is developed by combining mixed dimensional finite elements with the aid of multipoint constraint equations, which could be achieved from the energy conservation principle. Thus, the micro-scale damage details could be obtained in a macro-scale setting of the global structure. Furthermore, using different damage indicators, a generalized damage model is combined with the multilevel damage performance to assess the damage evolution. Finally, an in situ lateral loading test of a real RC frame structure was analyzed to verify this proposed damage assessment methodology. The finite element method utilizing the proposed damage model products results in good agreement with those of the tests. It shows that the proposed methodology is a very helpful tool to assess and reveal the inherent damage mechanism of RC structures.

Abstract:
Purpose The purpose of this paper is to advance our understanding of competitiveness. The authors introduce the concept of Competitive Productivity (CP), supplementing shortcomings of traditional understandings of national, organisational and individual productivity which overlook the nature of competitiveness, i.e. outperforming the competition, or at least bettering one’s own performance. The authors offer definitions, components and construct measurements of CP at three levels: macro, meso and micro. Design/methodology/approach A review of the literature was conducted to evaluate the need for combining productivity and competitiveness into one new construct. There are theories that combine these ideas – e.g., the resource-based theory of the firm – but the authors are presenting these concepts differently, or in a novel way. The authors’ focus on CP makes necessary a new group of construct measures which are different from that of the strategy literature: the authors measure an agent’s tendency “to be better than the competition” along multiple dimensions. Based on the CP construct, the authors present three testable models to uncover determinants of CP at three levels (macro, meso and micro). Finally, the work around “emergent property” can be applied to examine CP itself as being a determinant for other higher-order outcomes such as welfare, profits and life satisfaction. CP forms a platform to explore likely interplay (bottom-up and/or top-down mechanisms) within the micro–meso–macro architecture. Findings Three CP models were developed and are briefly discussed in this paper: first, a National Competitive Productivity (NCP) model to capture the components/drivers of national CP (macro level). Second, a Firm Competitive Productivity (FCP) model to capture the components/drivers of firm CP within an industry context (meso). And finally, an Individual Competitive Productivity (ICP) model capturing the components/drivers of CP at the individual (micro) level. Originality/value The study provides a combined approach to capture productivity and competitiveness within one innovative concept: CP. It can be used by government and policy makers (NCP model), managers and organisations (FCP model), and individuals such as workers and students (ICP model) to evaluate and enhance their performance. A better understanding of the components/drivers of CP at the three levels and the suggested measurement of CP should provide a stronger theory of competitiveness of nations, firms and individuals. Not least should a focus on the three levels (macro, meso and micro) better prepare citizens, firms, workers and students to effectively function and work in the marketplace and in society. The authors’ work should eventually contribute to more effective benchmarking and continuous improvement in the competitiveness domain. Crucially, this conceptual paper forms the foundation for future empirical testing of CP components in the context of the relative values and moderated behaviour as captured by the ReVaMB model.

Abstract:
The purpose of the research was to find out the effect of foliar fertilization with complex microfertilizers together with fungicides on the growth and development of plants and the yield of beet root in the Western Forest Steppe. Methods. Field, analytical and statistical. Results. It was found that the foliar fertilization of ADOB micro and macrofertilizers with the fungicide Impact in the Harold variety – 61.46 thousand m2/ha, and in Kestrel – 73.06 thousand m2/ha, provided the largest leaf area. The highest photosynthetic potential was in the Kestrel variety with foliar ADOB macro+micro compatibility with the Impact fungicide (2.37 million m2 × days/ha). Foliar fertilization of ADOB microfertilizers macro+micro with application rate of 2.0 kg/ha and fungicide Impact with application rate of 0.25 l/ha provides the highest weight of Harold root crops for the harvesting period at 413.0 g and Kestrel variety – 516.1 g. The introduction of ADOB macro+micro complex microfertilizers, in combination with Topsin M and Impact fungicides, provided the highest yield of beet root in Harold variety – 62.0-62.2 t/ha and Kestrel variety – 75.4-77.4 t/ha. The highest solids content and sugars were also observed in the variant, where they applied foliar ADOB macro+micro compound fertilizers with Topsin M and Impact fungicides in Harold variety - 15.6-15.7% and 8.5%, in Kestrel variety – 16.0-16.1% ??? 8.9%, respectively. The foliar fertilization of ADOB microfertilizer macro+micro in combination with the fungicide Impact provided the highest betanin content of 352.5 mg/100 g of raw weight in the Harold variety, and 270.9 mg/100 g of raw weight in the Kestrel variety. The combined application of ADOB microfertilizers macro+micro and fungicide Impact allowed to obtain maximum rates of profitability in the Kestrel variety - 241.6%, in the Harold variety - 182.3%.

Abstract:
Transformation induced plasticity steels (TRIP steel) is a kind of low – alloying high strength steel with good combination of strength and plasticity. But the macro mechanical properties depend on the microstructure greatly. For simulation, macro finite element can’t consider the microstructure development fully and micro molecular dynamics can’t be used in macro engineering widely, so to investigate the material behavior of trip steel a multi-scale simulation framework which combined macro finite element simulation and micro molecular dynamics together was presented in this paper. The transformation technology between macro and micro simulation by internal variable was considered and macro displacement of integral point as boundary condition of micro molecular dynamics was discussed.

Abstract:
Effective decision making uses various databases including both micro and macro level datasets. In many cases it is a big challenge to ensure the consistency of the two levels. Different types of problems can occur and several methods can be used to solve them. The paper concentrates on the input alignment of the households’ income for microsimulation, which means refers to improving the elements of a micro data survey (EU-SILC) by using macro data from administrative sources. We use a combined micro-macro model called ECONS-TAX for this improvement. We also produced model projections until 2015 which is important because the official EU-SILC micro database will only be available in Hungary in the summer of 2017. The paper presents our estimations about the dynamics of income elements and the changes in income inequalities. Results show that the aligned data provides a different level of income inequality, but does not affect the direction of change from year to year. However, when we analyzed policy change, the use of aligned data caused larger differences both in income levels and in their dynamics.

Abstract:
Purpose – Fatigue crack growth rate data for 2024-T3 aluminum are found using three parameters d*, σ* and μ* for short and long cracks for Regions I-III in conventional fatigue. Asymptotic solution of a line crack with a micro-tip is found to yield a singular stress behavior of order 0.75 in contrast to the 0.50 order known for the macrocrack. The difference is due to the micro-macro interaction effects. The three parameters account for the combined effects of load, material and geometry via the tip region. Data for short and long cracks lie on a straight with a slope of about 3.9-4.8 for R values of 0.286-0.565. The results were based on an initial crack a1 mm where a is the half length for a central crack panel. The paper aims to discuss these issues. Design/methodology/approach – The belief that specimen fatigue data could assist the design of structural components was upended when FAA discovered that the NASGRO FCGD are not valid for short cracks that are tight and may even be closed. The regular ΔK vs da/dN model was limited to long cracks. The issue become critical for short cracks connecting the long ones of a few mm to cm or even m according to da/dN for the same crack history. The danger of short/long fatigue crack growth (SLFCG) prompted FAA to introduce an added test known as Limit of Validity (LOV), a way of setting empirical limits for structural components. The dual scale SLFCG data from ΔK micro/macro provide support for the LOV tests. Findings – Data for short and long cracks lie on a straight with a slope of about 3.9-4.8 for R values of 0.286-0.565. The single dual scale relation on ΔK micro/macro can switch from microscopic to macroscopic or vice and versa. The difference is fundamental. Order other than 0.75 can be obtained for simulating different microstructure effects as well as different materials and test conditions. Originality/value – Scale shifting from short to long fatigue cracks for 2024-T3 aluminum is new. The crack driving force is found to depend on the crack tightness. The sigmoidal curve based on the regular ΔK plot disappeared. The data from ΔK micro/macro for short cracks may supplement the FAA LOV tests for setting more reliable fatigue safe limits.

Abstract:
Three methods for claims reserving are compared on two data sets. The first two methods are the commonly used chain ladder method that uses aggregated payments and the relatively new method, double chain ladder, that apart from the payments data also uses the number of reported claims. The third method is more advanced, data on micro-level is needed such as the reporting delay and the number of payment periods for every single claim. The two data sets that are used consist of claims with typically shorter and longer settlement time, respectively. The questions considered are if you can gain anything from using a method that is more advanced than the chain ladder method and if the gain differs from the two data sets. The methods are compared by simulating the reserves distributions as well as comparing the point estimates of the reserve with the real out-of-sample reserve. The results show that there is no gain in using the micro-level method considered. The double chain lad- der method on the other hand performs better than the chain ladder method. The difference between the two data sets is that the reserve in the data set with longer settlement times is harder to estimate, but no difference can be seen when it comes to method choice.
Tre reservsättningsmetoder jämförs på två dataset. De första två metoderna är den välkända chain ladder-metoden som använder sig av aggregerade utbetalningar samt den relativt nya metoden double chain ladder som förutom utbetalningarna använder sig av antalet anmälda skador. Den tredje metoden baseras på mikro-nivå och kräver information om varje enskild skada, såsom anmälningstid och antalet utbetalningsperioder. De två dataseten som används är ett som innehåller skador med typiskt kortare avvecklingstider och ett som innehåller skador med typiskt längre avvecklingstider. Frågorna som behandlas är om man vinner något på att använda en mer avancerad metod än chain ladder och om det skiljer sig åt mellan dataseten. Metoderna jämförs genom simulering av reserven, men också genom att jämföra punktskattningar med den verkliga reserven. Resultaten visar att man I detta fall inte vinner något på att använda mikro-metoden. Double chain ladder å andra sidan presterar bättre än chain ladder. Skillnaden mellan de två dataseten är att det är svårare att estimera reserven när avvecklingstiden är längre, men ingen skillnad ses när det gäller val av metod

Abstract:
Cette thèse examine la relation complexe et la causalité entre la migration et le développement, sujet d'actualité vus les flux croissants de migrants et les transferts de fonds privés. La revue de la littérature théorique et empirique montre la complexité de cette relation, et l’absence de consensus dégagé par les travaux menés sur les causes et les effets de la migration sur le développement. Sur les causes de migration, une première estimation empirique montre qu’elle fait partie intégrante du processus de développement et n’est donc pas une simple conséquence de faibles niveaux de développement: le niveau de développement des pays d'origine s’accroissant, les aspirations et les capabilités des populations augmentent et si celles-ci font face à l'absence d’opportunités, elles vont migrer à condition d’en avoir les capabilités (compétences requises, moyens financiers, politiques de migration, etc.). Concernant l’impact de la migration, une deuxième estimation empirique montre un effet positif sur le développement via les transferts privés. Les modèles indiquent que leur contribution se fait à travers deux principaux canaux, l'investissement en capital et le capital humain (éducation et santé), lesquels sont susceptibles de permettre un développement à long terme des pays d'origine. Au niveau micro, une troisième série de modèles étudie le mécanisme de cet impact au niveau de ménages, à partir du cas de l'Egypte. Ces modèles confirment l'importance des transferts privés sur les niveaux d'éducation et de santé dans les ménages qui les reçoivent. Ces résultats sont censés contribuer à la compréhension de cette relation complexe entre migration et développement
This thesis is concerned with the causal and complex relation between migration and development. A timely subject, especially with increasing flows of migrants and the remittances these migrants send home. Both the theoretical and empirical literature reviews address the complexity of this relation but consensuses on the causes and impacts of migration on development are generally inconclusive. On the causes of migration, our first empirical estimation shows that migration is part of the development process and not a simple result of its low levels: the increasing development level of the home countries increase the aspirations and capabilities of their populations and if these are faced with lack of opportunities at home, individuals seek migration provided they have the right capabilities (skills required, financial means, migration policies, etc.). On the impact of migration, our second empirical estimation gives evidence of a positive impact through remittances on the development of the home countries. The models show the positive contributions of remittances towards development through two main channels: capital investment and human capital (education and health). These two channels are believed to achieve long-term development of the home countries. At the micro level, we look at the mechanism of this impact at the household level, addressing the case study of Egypt. Our third models give evidence of the importance of these remittances in increasing both education and health status of the recipients’ households’. These findings are believed to make a contribution towards the understanding of this complex relation between migration and development

Abstract:
This work discusses the dynamic predictions of compliant mechanisms using the Pseudo-Rigid-Body model (PRBM). In order to improve the number of mechanisms that can be modeled, this research develops and identifies several key concepts in the behavior of beam segments where both ends are fixed to a rigid body (fixed-fixed flexible segments). A model is presented, and several examples are discussed. The dynamic behavior of several compliant segments is predicted using the PRBM and the results are compared to finite element analysis and experimental results. Details are presented as to the transient behavior of a typical uniform rectangular cross section beam. The results of this study are extended and applied to compliant planar mechanisms. It is shown by comparison with finite element analysis and experimental results that the PRBM is a good model of the physical system's dynamic behavior. The method is also demonstrated for use with compliant microelectromechanical (MEMS) systems.

Abstract:
The purpose of this research is to study how new knowledge is created, used, and shared at both micro- and macro- levels in healthcare organizations so as understand how this can improve evidence-based practice and provide new roles for information professionals to better EBM and clinical decision-making. Using Dervin's SMM as the primary research framework, supplemented with Snowden's Cynefin Framework for data analysis, the results demonstrated that individual knowledge was created in the gap-bridging process as the sense-making moment. Situation movement state and gap-bridging strategies were two predictors for knowledge creation. The knowledge gaps were identified and a wide range of gap-bridging strategies were employed to cross the gaps and create new knowledge. This micro process of knowledge creation is linked to the organizational level thorough knowledge sharing. This whole process of knowledge creation, utilization and sharing were mapped into a new micro-macro sense-making model, showing all the barriers and enablers identified in this research. These findings have filled the missing gaps in the literature and answered the long-standing question of how new knowledge is created in organizations. These findings would be able to shed new light to the practice of EBM. Some possible ways are to shift the attention to the use of medical knowledge, place more emphasis to the use of case-based reasoning approach, develop personalized medicine, and raise the importance of narratives in clinical practice. The new roles for information professionals in support for KM include: 1) the provision of different case-based reasoning systems; 2) use of IT tools in KM to assist clinicians to make sense of the situation; 3) taking user-centered verbing approach to organize knowledge sources; 4) building up expertise network; 5) use of narratives and storytelling for knowledge sharing; 6) engaging in virtual communities of practice; and 7) equipping library space to facilitate learning.

Abstract:
We investigate the implementation of nontraditional open-loop and closed-loop control techniques to systems at the micro and macro scales. At the macro level, we consider a quay-side container crane. It is known that the United States relies on ocean transportation for 95% of cargo tonnage that moves in and out of the country. Each year over six million loaded marine containers enter U.S. ports. Current growth predictions indicate that container cargo will quadruple in the next twenty years. To cope with this rapid growth, we develop a novel open-loop input-shaping control technique to mitigate payload oscillations on quay-side container cranes. The proposed approach is suitable for automated crane operations, does not require any alterations to the existing crane structure, uses the maximum crane capabilities, and is based on an accurate two-dimensional four-bar-mechanism model of a container crane. The shaped commands are based on a nonlinear approximation of the two-dimensional model frequency and, unlike traditional input-shaping techniques, our approach can account for large hoisting operations. For operator-in-the-loop crane operations, we develop a closed-loop nonlinear delayed-position feedback controller. Key features of this controller are that it: does not require major modifications to the existing crane structure, accounts for motion inversion delays, rejects external disturbances, and is superimposed on the crane operator commands. To validate the controllers, we construct a 1:10 scale model of a 65-ton quay-side container crane. The facility consists of a 7-meter track, 3.5-meter hoisting cables, a trolley, a traverse motor, two hoisting motors, and a 50-pound payload. Using this setup, we demonstrated the effectiveness of the controllers in mitigating payload oscillations in both of the open-loop and closed-loop modes of operation. At the micro level, we consider a micro optical device known as the torsional micromirror. This device has a tremendous number of industrial and consumer market applications including optical switching, light scanning, digital displays, etc. To analyze this device, we develop a comprehensive model of an electrically actuated torsional mirror. Using a Galerkin expansion, we develop a reduced-order model of the mirror and verify it against experimental data. We investigate the accuracy of representing the mirror using a two-degrees-of-freedom lumped-mass model. We conclude that, under normal operating conditions, the statics and dynamics of the mirror can be accurately represented by the simplified lumped-mass system. We utilize the lumped-mass model to study and analyze the nonlinear dynamics of torsional micromirrors subjected to combined DC and resonant AC excitations. The analysis is aimed at enhancing the performance of micromirrors used for scanning applications by providing better insight into the effects of system parameters on the microscanner's optimal design and performance. Examining the characteristics of the mirror response, we found that, for a certain DC voltage range, a two-to-one internal resonance might be activated between the first two modes. Due to this internal resonance, the mirror exhibits complex dynamic behavior. This behavior results in undesirable vibrations that can be detrimental to the scanner performance. Torsional micromirrors are currently being implemented to provide all-optical switching in fiber optic networks. Traditional switching techniques are based on converting the optical signal into electrical signal and back into optical signal before it can be switched into another fiber. This reduces the rate of data transfer substantially. To realize fast all-optical switching, we enhance the transient dynamic characteristics and performance of torsional micromirrors by developing a novel technique for preshaping the voltage commands applied to activate the mirror. This new approach is the first to effectively account for inherent nonlinearities, damping effects, and the energy of the significant higher modes. Using this technique, we are able to realize very fast switching operations with minimal settling time and almost zero overshoot.

Abstract:
The effect of budgetary participation on managers' performance and satisfaction has received a considerable amount of attention over the past three decades. Accounting literature has witnessed many contributions that attempted to check the nature of these two relationships and to investigate the variables which may have clear or hidden effects on them. Researchers went beyond accounting literature to study organisational and psychological theories and adopted some dimensions from each and tested these dimensions on those relationships. Scholars found different organisational variables (e. g. organisation size, environment uncertainty, technology, information asymmetry) and also behavioural. variables (e. g. locus of control, budget goals difficulty and clarity, motivation, slack) which affected the relationship between budgetary participation and both managers' performance and satisfaction. Culture has been also used as a possible contingent variable which may play a role in this conflicting area. Behavioural accounting research witnessed many efforts which investigated the effect of culture on budget-related behaviour. Nevertheless, the results were inconclusive. Prompted by the inconsistent results reported in the previous work, this study was designed to provide more insight for this area through three main purposes: 0 Constructing an integrative model which consists of eighteen variables which have been frequently used in the previous work. 0 Testing the proposed model using sample of managers from different cultures. 0 Testing the proposed model using two analytical approaches "moderating and intervening". Twenty eight hypotheses were used to develop the proposed model. Some hypotheses have been replicated, whereas others have been developed because they receivedli ttle attentioni n the previouss tudiesU.

The results of this study showed that both macro and micro level variables interact with budgetary participation affecting managers' performance and satisfaction. The results have highlighted the importance of using an integrative model as a way to reconcile the contradictory results reported in the previous work. With respect to the culture, the results provided evidence that budgetary control practices are different between UK and Saudi Arabia in some aspects, whereas no cultural differences were observed in others. For example the results showed that the effect environment uncertainty on budgetary participation, and the effect of budgetary participation on managers' satisfaction are culturally independent. The results of the proposed model showed that some relationships (e. g. the effect of leadership style on budget emphasis) are different between locals and non-locals within the single country. The results of this study also provided evidence that the contradictions in the previous work could be reconciled by using the appropriate analytical approach. Some hypotheses were supported using the moderating approach whereas others were supported using the intervening approach. Therefore, this study showed that these two approaches are complementary and both should be used either to support or reject a hypothesis.

Abstract:
AbstractThe links between loneliness and overall morbidity and mortality are well known, and this has profound implications for quality of life and health and welfare budgets. Most studies have been cross-sectional allowing for conclusions on correlates of loneliness, but more recently, some longitudinal studies have revealed also micro-level predictors of loneliness. Since the majority of studies focused on one country, conclusions on macro-level drivers of loneliness are scarce. This chapter examines the impact of micro- and macro-level drivers of loneliness and loneliness change in 11 European countries. The chapter draws on longitudinal data from 2013 and 2015 from the Survey of Health, Aging, and Retirement in Europe (SHARE), combined with macro-level data from additional sources. The multivariable analysis revealed the persistence of loneliness over time, which is a challenge for service providers and policy makers. Based on this cross-national and longitudinal study we observed that micro-level drivers known from previous research (such as gender, health and partnership status, frequency of contact with children), and changes therein had more impact on loneliness and change therein than macro-level drivers such as risk of poverty, risk of social deprivation, level of safety in the neighbourhood.

Abstract:
Abstract Within the class of procedures termed minimally invasive glaucoma surgery (MIGS), the iStent Trabecular Micro-Bypass Stent (Glaukos Corporation, San Clemente, CA, USA) is an intraocular implant that resides within Schlemm’s canal and allows for direct bypass of the trabecular meshwork by aqueous fluid. The acceptance of MIGS is growing due to its role in lowering intraocular pressure in mild-to-moderate glaucoma combined with its favorable safety profile. With transscleral glaucoma-filtering surgery, there is an increased potential for significant complications including hypotony, suprachoroidal hemorrhage, and long-term risk of endophthalmitis. By contrast, the iStent minimizes these risks and has demonstrated similarities to cataract surgery in terms of associated complications. Multiple publications have described both the safety and efficacy of the implant. These studies are reviewed in addition to a description of the implantation technique and postoperative management pearls. The second-generation model, the iStent inject, may ease implantation and the use of multiple stents may potentially play a role in more advanced disease.

Abstract:
The importance of the Word of Mouth is growing day by day in many topics. This phenomenon is evident in everyday life, e.g., the rise of influencers and social media managers. If more people positively debate specific products, then even more people are encouraged to buy them and vice versa. This effect is directly affected by the relationship between the potential customer and the reviewer. Moreover, considering the negative reporting bias is evident in how the Word of Mouth analysis is of absolute interest in many fields. We propose an algorithm to extract the sentiment from a natural language text corpus. The combined approach of Neural Networks, with high predictive power but more challenging interpretation, with more simple but informative models, allows us to quantify a sentiment with a numeric value and to predict if a sentence has a positive (negative) sentiment. The assessment of an objective quantity improves the interpretation of the results in many fields. For example, it is possible to identify crucial specific sectors that require intervention, improving the company's services whilst finding the strengths of the company himself (useful for advertising campaigns). Moreover, considering that the time information is usually available in textual data with a web origin, to analyze trends on macro/micro topics. After showing how to properly reduce the dimensionality of the textual data with a data-cleaning phase, we show how to combine: WordEmbedding, K-Means clustering, SentiWordNet, and the Threshold-based Naïve Bayes classifier. We apply this method to Booking.com and TripAdvisor.com data, analyzing the sentiment of people who discuss a particular issue, providing an example of customer satisfaction.

Abstract:
In the present study, heat transfer in a falling film micro groove evaporator has been simulated by an analytical model. The flow and thermal fields were divided in two regions, i.e. macroscopic flow inside the groove and the microscopic flow where intensive evaporation takes place at the thin film interline region. For the micro region model, pressure in the liquid film was expressed as a sum of surface tension and disjoining pressure effects. The film thickness profile was obtained by solving the 4th order differential equation by Runge-Kutta method. Then, this micro region model was combined with the macro region model. Macro region model solves one dimensional bulk flow inside the groove with gravitational effect taken into account. Constant curvature of the liquid vapor surface was assumed for the macro flow. It is shown that the gravitational force is essential for providing the liquid to wide range of heat transfer area. Thus, diverging branch evaporator is investigated. It is demonstrated that this concept has large potentiality for improving the performance of the micro groove falling film evaporator.

Abstract:
Scaling effects in continuum flows can be identified that characterize flow and heat transfer in small, micro-sized devices compared to the same geometries but on a macro-sized scale, when the underlying continuum equations (Navier-Stokes and first law of thermodynamics) are subject to a dimensional analysis. In order to identify micro scaling effects experimentally, measured flow quantities are compared to numerically calculated results, based on a theoretical model that is appropriate for macro scale channels (no scaling effects, continuum approach). They have to be interpreted carefully, including a thorough error analysis of experiments as well as the theoretical model. Instead of trying to experimentally identify scaling effects in fixed geometries we suggest to combine macro parts in a way that micro channels emerge. Then, continuously adjustable sizes of the channels can be realized that go from macro to micro dimensions. Equally important, the surfaces of the channels are freely accessible when the macro parts are disjoined. Two such facilities are shown and discussed.

Abstract:
A micro-macro simulation algorithm for the calculation of polymeric flow is developed and implemented. The algorithm couples standard finite element techniques to compute velocity and pressure fields with stochastic simulation techniques to compute polymer stress from simulated polymer dynamics. The polymer stress is computed using a microscopic-based rheological model which combines aspects of network and reptation theory with aspects of continuum mechanics. The model dynamics include two Gaussian stochastic processes each of which is destroyed and regenerated according to a survival time randomly generated from the material’s relaxation spectrum. The Eulerian form of the evolution equations for the polymer configurations are spatially discretized using the discontinuous Galerkin method. The algorithm is tested on benchmark contraction domains for a polyisobutylene (PIB) solution. In particular, the flow in the abrupt die entry domain is simulated and the simulation results are compared with experimental data. The results exhibit the correct qualitative behavior of the polymer and agree well with the experimental data.

Abstract:
The electric power density generated in co-flow planar solid oxide fuel cells (SOFCs) with porous composite electrodes is predicted using the cell combined micro- macro-model; and the effect of the microstructural variables of the electrodes on the cell power generation is studied. In the combined micro- macro-model, the electrochemical performance of the porous composite electrodes is determined from the micro-model and the distributions of the temperature in solid structure of the cell and the temperature and species partial pressures of the bulk fuel and air streams are determined from the cell macro-model. As a case study, the effect of the microstructural variables of the porous composite electrodes of the Ni-YSZ/YSZ/LSM-YSZ cell operated at the given voltage, fuel utilization ratio, and excess air, on the average power density of the cell is investigated through computer simulation. The results reveal that there is an optimum value for each microstructural variables of the electrodes at which the cell power density is maximized.

Abstract:
Traumatic brain injury (TBI) occurs in many blunt, ballistic and blast impact events. During trauma axons in the white matter are especially vulnerable to injury due to the rapid mechanical loading of brain. The axonal pathology leads to cytoskeletal failure and disconnection. The microtubules are one of major structural components of the cytoskeleton filamentous network. By bridging the macroscopic forces acting on the whole brain with the cellular and subcellular failure, the macro-micro computational models in both time and space can help us better understand the complex biophysics and elucidate the injury mechanism of both severe and mild TBI (concussion). At the macroscopic scale we developed the high-fidelity anatomical human body finite element model (FEM) to predict intracranial pressures and strain and strain rate fields of brain in the blast event. The macro-scale models and the coupled blast and biomechanics approach were validated against test data of shock wave interacting with a surrogate head in the shock tube. The mechanical deformation of brain tissue was mapped to the white matter tracts to obtain local axonal strain and strain rate for the micromechanical models. We developed the micromechanical FEM of myelinated axons interconnected with the oligodendrocyte by the processes, utilizing a novel beam element free of rotational degrees of freedom (DOFs). The numerical results reveal the possible mechanism of impact-induced axon injury including demyelination, breakup of processes, and axonal varicosity. We also investigate the dynamic response of microtubules bundles under traumatic loading. Different from the commonly discrete bead-spring models, a network of microtubules cross-linked with microtubule-associated-protein (MAP) tau proteins was modeled by the nonlinear beam model. Tau protein is modeled by the rate-dependent bar element for its complicated material behavior. The model considers the rupture of microtubule and the failure of tau-tau interface and tau-microtubule interface. The simulation result of the combined effects of the failure of the cross-linked architecture and elongation and bending of the bundle are possibly correlated to the axonal undulations following traumatic loading observed in the experiments. The developed macro-micro biomechanics models can be used as a starting point for modeling the neurobiology effects and guide the design of novel injury protection strategies.

Full text
Abstract:
Modal vibration testing and static flexure testing at the macromechanical level combined with numerical finite element (FE) models have been used to indirectly determine the elastic moduli of 6111 aluminum alloy base metal and spot friction welded (SFW) joints which have been formed at different processing times. It was observed that the frequency (and the corresponding apparent stiffness) of the joint oscillates at low amplitudes as processing time increases. For each vibration mode, the amplitude of the oscillation in the frequency vs. processing time is only a few percent of the mean frequency with 99% confidence level, while the corresponding lap shear strength increases monotonically by a factor of about 8 as the processing time increases. Due to the scatter in the damping data it is difficult to detect any significant trends. Comparison of predicted modal frequencies and static load-displacement response of SFW joints at the macromechanical level with the corresponding measured responses seems to indicate that the weld zone is not as stiff as the base metal, but more detailed micromechanical analysis is required before definite conclusions can be drawn. In addition, studies of microstructural characteristics and Vickers microhardness distributions across the weld zone for the SFW samples reveals the formation of a partial metallurgical bond in the direction of flow, which is governed by the tool used, whereas the hardness distribution in the weld zone depends on the processing time.

Abstract:
This paper reports the overall picture of our ongoing efforts to establish the scientific understanding of ultrafast, non-equilibrium laser-material interactions from nanometer to milimeter and from femtosecond to microsecond through comprehensive, integrated multiscale physico-chemical modeling and experimental verification. A novel plasma model with quantum treatments is developed to account for significantly varying optical properties. The model is used to successfully predict two uncommon phenomena that is experimentally observed: 1) a flat-bottom crater shape created by a Gaussian beam and 2) repeatable nanoscale structures achieved by pulse train technology. The well known two-temperature model is improved by considering the quantum effects of different heat carriers and then is used to accurately predict the damage thresholds for metals. Preliminary results for these ongoing modeling efforts are reported in this article.

Micro-terrain and canopy feature extraction by breakline and differencing analysis of gridded elevation models : identifying terrain model discontinuities with application to off-road mobility modeling.

Full text
Abstract:
Elevation models derived from high-resolution airborne lidar scanners provide an added dimension for identification and extraction of micro-terrain features characterized by topographic discontinuities or breaklines. Gridded digital surface models created from first-return lidar pulses are often combined with lidar-derived bare-earth models to extract vegetation features by model differencing. However, vegetative canopy can also be extracted from the digital surface model alone through breakline analysis by taking advantage of the fine-scale changes in slope that are detectable in high-resolution elevation models of canopy. The identification and mapping of canopy cover and micro-terrain features in areas of sparse vegetation is demonstrated with an elevation model for a region of western Montana, using algorithms for breaklines, elevation differencing, slope, terrain ruggedness, and breakline gradient direction. These algorithms were created at the U.S. Army Engineer Research Center – Geospatial Research Laboratory (ERDC-GRL) and can be accessed through an in-house tool constructed in the ENVI/IDL environment. After breakline processing, products from these algorithms are brought into a Geographic Information System as analytical layers and applied to a mobility routing model, demonstrating the effect of breaklines as obstacles in the calculation of optimal, off-road routes. Elevation model breakline analysis can serve as significant added value to micro-terrain feature and canopy mapping, obstacle identification, and route planning.

Abstract:
Externalities and private information are key characteristics of an epidemic like the Covid-19 pandemic. We study the welfare costs stemming from the incomplete information environment that these characteristics foster. We develop a framework that embeds a game theory approach into a macro SIR model to analyze the role of information in determining the extent of the health-economy trade-off of a pandemic. We apply the model to the Covid-19 epidemic in the US and find that the costs of keeping health information private are between USD $5.9$ trillion and USD $6.7$ trillion. We then find an optimal policy of disclosure and divulgation that, combined with testing and containment measures, can improve welfare. Since it is private information about individuals' health what produces the greatest welfare losses, finding ways to make such information known as precisely as possible, would result in significantly fewer deaths and significantly higher economic activity.
