Abstract:
There is an emerging confusion in scientific literature between reflexivity and self-reflectivity. Self-reflectivity is a self-awareness of oneself own conduct to self-regulate feelings, thinking and action to reproduce acceptable social norms such as professional and socially best practices as citizens. Rather, reflexivity emerging literature refers to a metaconscious critical intellectual process and experiential transforming feelings, thinking and action to create new knowledge, innovate new actions and even improve resilience capability. This research argues that knowing how to do reflexivity will it as a transformative force enabling human development. The research question is: How to apply Reflexibility for Knowledge Development, Innovation and Resilience and what are the benefits? To answer this question a 17 year-long (2005-2022) experimental phenomenological action research was conducted. Findings reveal how reflexivity can be applied to one’s life experience, but also to knowledge, beliefs and values reaching ideological and social norms critical awareness enabling knowledge development and innovating new actions as an ability to practice resilience. The discussion addresses the long-term benefits of practicing reflexivity applied on knowledge and innovation building empowerment and resilience capability.

Abstract:
With the development of intelligent technology, it is of great significance to develop intelligent equipment with topography self-sensing function. The micro morphology perception technology applied to intelligent equipment is the key technology for development. In this paper, at first, topography perception theory based on the PVDF (Polyvinylidene Fluoride) technology is researched, then an experimental study is conducted to sense the characteristic points of the geometric curve of the preset topography surface used in the PVDF film, and then the Ferguson curve model is used to reconstruct the topography characteristic curve. The experimental results show that the reconstruction curve can truly reflect the features of the characteristic curve of the surface of the preset topography, and the feasibility of topography surface sensing technology by PVDF sensing technology is verified. The research provides technical support for the development of intelligent equipment with topography self-sensing function.

Full text
Abstract:
The development of high-throughput sequencing (next-generation sequencing technology (NGS)) and the continuous increase in experimental throughput require the upstream sample processing steps of NGS to be as simple as possible to improve the efficiency of the entire NGS process. The transposition system has fast “cut and paste” and “copy and paste” functions, and has been innovatively applied to the NGS field. For example, the Assay for Transposase-Accessible Chromatin with high throughput sequencing (ATAC-Seq) uses high-throughput sequencing to detect chromatin regions accessible by Tn5 transposase. Linear Amplification via Transposon Insertion (LIANTI) uses Tn5 transposase for linear amplification, haploid typing, and structural variation detection. Not only is it efficient and simple, it effectively shortens the time for NGS sample library construction, realizes large-scale and rapid sequencing, improves sequencing resolution, and can be flexibly modified for more technological innovation.

Based on analysis of water inrush coefficients developed and applied in deep coal mining with high water pressure, the author proposes that there are some defects of water inrush coefficients in calculation and application. By simulation experiments on the water resistance properties of the aquiclude in a coal seam floor, the author arrived at the distribution and digital characteristics of residual pressure in the course of high-pressure water rising in the water-resisting floor. The formula for a water inrush coefficient has been further revised.

Numerical methods progress rapidly in terms of capabilities and efficiency. Accordingly, one could conclude that experimental activities will sooner or later disappear. In this context the paper will exemplify the use of numerical methods for the proper design and conduct of wind tunnel experiments. Examples will cover the research topics on high lift system's aero-acoustic and landing gear noise. Finally, the paper will describe the development of selected noise reduction concepts from their first experimental assessment in wind tunnels up to being flight tested.

Abstract:
Several kinds of research conclude that the level of digital competence of students is mainly oriented to their daily activities. Therefore, we present the current paper which seeks to determine the impact of implementing a blended learning course designed to improve digital competence for research (DCR) among a group of undergraduate engineering students. With this approach, a quasi-experimental explanatory methodology with a causal-comparative scope was applied. For this reason, the results were analyzed before and after applying a specially designed course to the experimental group, comparing it with a passive control group by collecting data using three previously validated instruments. For data analysis, students’ t-tests and two-way ANOVA (Analysis of Variance) were used, estimating the effects with Cohen’s study. Given the results, there was a statistically significant improvement (p ≤ 0.05) in their skills and attitudes, but not in their knowledge, obtaining a significant effect size only in the procedural dimension (f = 0.41 y η2 = 0.142). Therefore, the implementation of the course used in the blended learning modality is considered to significantly improve the DCR of a group of undergraduate engineering students, although the results should be evaluated with due reservations.

Abstract:
A wide range of research fields have studied how emotions and behavior are affected by the physical environment. This gestalt theorist approach of experimental research as well seeks to measure emotion (using the valence-arousal scale) and micro-scale community development interactions when weighted physical environment factors are adjusted. Community development (CD) interactions at the micro-scale have received but slight attention from scholars in the CD research field and this study aims partially to investigate developing objective measures from social observations. CD interactions from recordings along with self-reported emotion through surveys in four quasi-experimental groups (where the environments were constructed based on peer-reviewed literature to cause emotional reactions) and one control group made up the data collected for this experiment. While the results of this experiment displayed apparent convincing quantitative differences in both CD interactions and emotion when the physical environment was manipulated, the results of a one-way ANOVA indicated no statistical significance to either dependent variable. The conclusions suggest limiting the physical factors of the environment to produce more precise changes as a result of the manipulated quasi environments.

Abstract:
<p>This study traces the evolution of the applied ecological discipline of range management in terms of the goals, methods, concepts, and criteria developed by range management for their science between 1897 and 1920. It argues, in contrast to the traditional view uÌ uat describes the knowledge-development process in applied science as just science applied to social problems, that wider social goals, values, concepts, and criteria play a definite role in shaping the applied science knowledge-development process.</p> <p> The first generation of range management allowed the primary users of the knowledge in the wider society, the stockmen in the West and Southwest, to have a direct influence on the knowledge-development process. The next generation of scientists eliminated the stockmen's direct influence on the knowledge-development process, yet the stockmen still influenced that process indirectly in various ways.</p> <p>This study concludes that an orientation towards the wider society that actually applies the knowledge is characteristic of range management and may be illustrative of illustrative of many applied sciences. Due to that orientation towards the wider society and to the wider society's influence on the scientist's choice of methods,concepts, and criteria, another characteristic of range management and possibly of other applied sciences is a tension in the knowledge development process between that orientation and the individual goals of scientists in their research.</p><br>Master of Science

Abstract:
Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico<br>A presente dissertaÃÃo de mestrado trata do desenvolvimento teÃrico-experimental de um novo modelo da Turbina Tesla, tambÃm conhecida como turbina de discos, em que o foco da pesquisa foi estudar esse dispositivo de propulsÃo visando sua aplicaÃÃo em sistemas de geraÃÃo de energia distribuÃda a partir de fontes renovÃveis de biomassa. Um protÃtipo da turbina foi desenvolvido, em escala de laboratÃrio, para determinar os parÃmetros de projeto atravÃs de estudos teÃrico e experimental, a fim de interpretar os fenÃmenos presentes nos processos internos desse tipo de mÃquina de fluxo. A pesquisa foi direcionada à anÃlise dos efeitos do espaÃamento entre discos sobre o torque e a potÃncia, como uma funÃÃo da camada limite fluidodinÃmica do escoamento, correlacionando os regimes de velocidades de escoamento Ãs propriedades do fluido de trabalho. A metodologia para cÃlculo das eficiÃncias isentrÃpicas e exergÃticas à estabelecida a partir de dados experimentais e da anÃlise teÃrica por simulaÃÃo (apoiada pelo software ANSYS-CFX), a qual determina o perfil de distribuiÃÃo de pressÃo dentro da cÃmara de expansÃo, caracterizando as linhas de escoamento e os gradientes de pressÃo. Complementarmente, uma anÃlise modal dos sinais de vibraÃÃo da turbina foi realizada, estudando o comportamento dinÃmico da estrutura com o propÃsito de detectar as freqÃÃncias naturais e investigando a influÃncia do espaÃamento dos discos sobre o nÃvel de vibraÃÃodesse dispositivo. Este estudo aponta a robustez e a versatilidade operacional desse tipo de turbina, pelo fato dela admitir ampla faixa de rotaÃÃo e por sua fÃcil adaptaÃÃo a geradores comerciais, sugerindo sua aplicaÃÃo em sistemas de geraÃÃo e co-geraÃÃo tanto para o meio rural como para a indÃstria.<br>The current masterâs dissertation treats the experimental and theoretical development of a new model of Tesla turbine, also known as disk turbine, in which the research focus was to study this propulsion device viewing its application in distributed energy generation systems from biomass renewable resources. A turbineâs prototype was developed, in laboratory scale, to determine the design parameters through the theoretical and experimental studies in order to interpret the phenomena present in the internal processes of this kind of flux machine. The research was directed toward the effect analysis of the gap between disks on the torque and the power, as a function of the flowâs fluidynamic boundary layer, correlating the flow velocity regimes with the working fluid properties. A methodology for isentropic and exergetic efficiency calculation is taken from experimental data and theoretical analyses through simulation (supported by the software ANSYS-CFX), which determines the pressure distribution profile inside the expansion chamber, characterizing flow lines and pressure gradients. Complementarily, a modal analysis of turbineâs vibration signals is performed, studying the dynamic behavior of the structure with the purposes of detecting the natural frequencies and investigating the influence of the diskâs gap on the vibration level of this device. This study points out the robustness and the operational versatility of this kind of turbine by the fact of it allows a wide rotation range and by its easy adaptation to commercial generators, suggesting its application into generation and co-generation systems for the rural area as well as for the industry.

Abstract:
Social interactions are constant and ongoing exchanges between individuals, which require both personal and social skills. These skills have been named in many different ways, as soft skills, transversal skills, general skills, key skills, etc. and have in recent years become a hot topic of research. In fact, it has been demonstrated that possessing them results in creating more value both in one’s workplace, while enhancing one’s hard skills, and also in one’s personal life. Two interrelated skills used in our daily lives: Negotiation and Persuasion, are the object of analysis of this study. This thesis aims at defining them together with existent links with some of the other main soft skills, in particular Empathy, and at examining the most renowned training methodologies. It focuses particularly on the analysis of the effectiveness of the development methodologies applied by the Ca’ Foscari Competency Centre, analysing data acquired from the students participating at the “Competenze in Pillole” of Negotiation and Persuasion. Many academic articles have been published regarding the concepts and the strategies of these two skills, but there are hardly any studies relative to practical self-development approaches and their outcomes. Therefore, this thesis intends to analyse this aspect, which is important and useful for students who approach the labour market and seek employment. It’s a research that paves the path for further related studies deferred by age, university, nationality, work experience, and other variables.

Abstract:
Abstract This chapter presents the main approaches and methodologies for studying the relationship between input and the development of L2 French in general and in instructional settings. The chapter first introduces research methods that target the description of French as linguistic input to L2 learners of French and, second, research methods in instructional settings. These two research fields are illustrated with examples mainly from recent publications and address the study of French as input to L2 (classroom) learners, corpora as a research tool and (experimental) classroom interventions designed for the study of specific teaching activities on L2 learning. The chapter concludes with a number of ethical considerations specific to these two methodological approaches, followed by a conclusion and suggestions for future research.

Abstract:
Abstract This paper reviews research on child L2 French (cL2) published since 2000 with a focus on research areas and methodology in a broad sense. The aim of the review is to identify methodological trends in the research, to exemplify, and to provide a discussion of prominent features. The review shows that research on cL2 French has mainly focused on the acquisition of morphosyntax based on oral production data. There are few longitudinal studies while experimental research focusing on comprehension and online processing is largely lacking. Despite being a world language, the number of different settings and L1s in cL2 French research is limited. Following trends in bilingualism research, methods for studying exposure and input have developed from an initial reliance on the Length of Exposure measure to more sensitive measures of relative exposure, but there are still few studies presenting any absolute measures of input. In recent years, a focus on the use and development of standardized tests for clinical purposes is noticeable. The review also shows that reporting practices concerning ethical considerations need to become more consistent in the future.

Full text
Abstract:
AbstractAfter reviewing previous research strategies applied to evaluate the impacts of EU urban initiatives, and previous evaluative assessments of similar place-based initiatives, this chapter proposes the use of ‘controlled comparisons’ to perform this crucial task for the urban dimension of the European Cohesion Policy: analyses should compare changes before and after interventions between territorial targets and appropriate contrafactual. Previous studies on policy effectiveness have analysed programme outcomes or case studies, but their results do not provide information about initiatives’ impacts due to the lack of contrafactual comparison. Besides, urban initiatives establish some ‘eligibility criteria’ to select their territorial targets. Therefore, contrafactual should be chosen according to the criteria. Based on these ideas, this chapter applies propensity score matching to select appropriate experimental and control groups to evaluate the impact of EU urban initiatives in Spain. The following chapters use the chosen neighbourhoods (experimental and control groups) to perform impact analyses using different methodological approaches.

Innovative construction materials and techniques can be sourced from natural resources and traditional methods, and applied to green housing concepts to enhance energy efficiency and occupant well-being. Innovation in vernacular traditions can be achieved by integrating the modern, current methods and techniques, materials and tools within local traditional technologies and associated natural raw materials (clay, sand, wood, straw, and wool) in order to enhance ecologic housing facilities with improved overall performance: structural, economic and sustainable. The current paper focuses on development of poured earth walls as an eco-friendly alternative to classic solutions (masonry, concrete walls, etc.), specifically on the clay-based mix design feasible for the poured earth technique. This technique resembles natural concrete, aggregate grains are bonded by clay particles instead of cement-based binding systems, and it offers environmental benefits such as facile recyclability, low impact, and effective hygrothermal regulation, but also brings consistent challenges regarding the proper clay-based earthen mix design. Preliminary and exploratory fresh-state testing is performed on several clayey mixes, in order to identify critical parameters with further relevance to the structural and durability performance, together with specific comparative evaluation and corresponding conclusions related to overall concept feasibility.

Abstract:
Purpose With the promulgation of China's "Three-child Policy", the cardinal number of children population has surged. The era of parent-child format arrives. Since ancient times, China has emphasized on education. With the development of the internet, people have improved the Chinese character position unprecedently. In recent years, the game education APP of mobile terminal has developed with irresistible force due to the development of the mobile devices and the influence of COVID-19. But due to its virtual property, offline interaction is weak, and it isn't easy to review and memorize. The preschool children at the age of 3-6 focus on the concrete thinking, and their recognition to external things mainly depends on the concretization and representation of things and the association of representation, accordingly constructing knowledge. Therefore, under the trend of reduction of excessive homework burden and off-campus tutoring, it is critical to inquire how to effectively build the popular online and offline "AR game gene" in design research. Method The significance and opportunity for etymon literacy method to be introduced to children Chinese game design is found through theoretical research; The AR technology is used in practice through technical research to build the design method of virtual and real interaction; The law of development of Children's cognition and motion interaction is researched and the characteristics of word root and grapheme of Chinese characters are split and combined to find the coherence point of Children's cognitive development and literacy method and design a set of suitable Chinese character formula, excavating the similarity of word formation thought and design thought, and enlightening children's thought with word formation; Results Chinese character laboratory aims at the children at the age of 3-6 [critical period of Whole Brain Development], is oriented by the development of multiple intelligence of children, and takes AR foundation as technological base. The whole design research is analyzed in this paper and the work formation process is summarized. Conclusions The etymon literacy method and AR experimental game are of important innovative significance in children's thinking development. Chinese character laboratory fully considers the uniqueness of children in social cognition in design through etymon literacy method, will utilize children's curiosity to introduce laboratory concept, namely experiment is game, and conducts series connection of commonly used characters in the form of Chinese character atlas from fragment to systematization. In the meanwhile, AR children's interactive games are characterized by the vivid and interesting virtual Chinese character model, entity Chinese character card, AR technology's unique interactivity, immersion and imagination, and utilize the computer technology to achieve interaction, conforming to the children's concrete thinking. In the future, technology will gradually replace mankind's left brain for calculation and analysis, but the creative thinking controlled by right brain can't be substituted by technology, because the knowledge is limited, but the imagination and creativity are limitless. This design breaks through the boundedness, singleness and fragmentization of current Chinese character literacy for children, which not only can promote the development of comprehensive quality and creative thinking, but also can help children learn Chinese characters in open thinking. So it is considered as a key to develop the potential of children in all directions.

Abstract:
According to the development of the concept of “zero failure” or “zero fuel element defect”, accepted in 2011, which consists in reducing the number of fuel elements that are depressurized in the process of operation to the reached level in the leading countries in nuclear energy (10−6–10−5 defective fuel rods) and avoidance of fuel assemblies with non-hermetic cladding of fuel rods for further operation, including defects with a “gas leak” type, new promising fuels are being developed and introduced, including methods for justifying their safety. Thus, to ensure reliability and safety of new fuel types, it is necessary to provide procedures for monitoring current performance characteristics at all stages of the life cycle of fuel rods. In this paper, experience is given on the development and implementation of instrumentation and methods for monitoring of fuel rods with advanced types of nuclear fuel for VVER reactors that ensure the reliability, safety and competitiveness of technologies associated with the use of advanced fuel rod types, and the implementation of associated components, systems and equipment for monitoring and diagnostics. The features of the applied techniques are presented, and the new system of requirements for the implemented equipment created on their basis. This research continues, and the analysis of intermediate experimental data is carried out in this article.

Abstract:
ABSTRACT Introduction. As the industry experts like to say: “The mountain guide is the guide at the ‘’Museum of Nature’’. But what distinguishes these people who “do not stay anywhere longer than their enthusiasm’’? The training of mountain guides is carried out in the Professional Education Center part of the National Agency for Vocational Education and Training. The training begins with an entrance exam, which assesses the preparation of candidates, and subsequently, the results are used to rank for the upcoming training. The purpose of our research is the development of an experimental methodology for evaluating the preliminary training of candidates for mountain guides. Methods. The research was held in 2022 at the Professional Education Center “Mountains and people”. Our methods included several criteria: moving on a mountain route with a topographic map crossing terrain, a theoretical test, and an intervthese criteria formed an overall score with a maximum score of 20 points. We applied our method to 29 participants. Results: Our participants showed an average time of 4 h 38 min for moving on a mountain route with a topographic map and crossing terrain. These times corresponded with an average of 8.8 points in our evaluation method. The average score for the theoretical test was 3.3 points, and the average score for the interview was 3.8 points. The average overall score was 14.8 points, which we define as very informative for the selection of candidates for mountain guides. Conclusion. We recommend this assessment methodology to National Agency for Vocational Education and Training. It is likely to be implemented in the examination requirements of all Professional Education Centers in the country.

Abstract:
Offshore oilfield generally has the characteristics such as high oil content of produced liquid and limited platform space etc, so it is urgent to design a kind of dewatering processing equipment with the following advantages such as small volume, high efficiency and low energy consumption etc. And the dewatering hydrocyclone studied in this paper is such a device which is mainly applied for the dehydration of crude oil in offshore oilfield exploration and development. Hydrocyclone named as the Thew type with double cones double inlets is taken as the initial model, meanwhile the physical medium parameters close to oil pipe of Bohai Sea is selected. Applying computational fluid dynamics (CFD) method, and by means of the Reynolds Stress Model and SIMPLEC algorithm in the FLUENT analysis software, the influence of structural parameters and operating parameters on the pressure field, velocity field and oil phase distribution of dewatering hydrocyclone is analyzed systematically. Some structural parameters, including swirl chamber diameter, underflow pipe length, large cone angle, small cone angle, the diameter of the overflow pipe, overflow pipe length and inlet section size etc, are optimized. A kind of main structure of dewatering hydrocyclone is determined, which can deal with about 40% of the oil-water mixtures for dewatering processing, and the comprehensive separation efficiency is higher. The numerical simulations and the experimental research results in this paper have a great influence on the advanced study and application of dewatering hydrocyclone and provide certain theory evidence for further research on flow field analysis and design improvement.

Abstract:
The central thesis of this paper is that e-learning courses can have a significant impact on English language for specific purposes (ESP) proficiency of mining mechanical engineering students. The purpose of this study is to assess the effectiveness of ESP Moodle-based course “English for Mining Mechanical Engineers” and to reveal the results of its experimental approbation. In order to identify the lectures’ and learners’ needs we have applied the survey research. The survey confirmed the greatest demand for Moodle courses that include all the elements of a coherent training manual to provide self-development of engineering students. The interview results contributed to design of author’s ESP course syllabus. The importance and originality of this study are that to approbate the course materials’ effectiveness two approaches have been adopted simultaneously. The first is blended learning method based on e-learning platform applied in the experimental group and the second one is classic in-class instructor-led studying used in a control group. Students’ progress in ESP proficiency has been assessed using the cross assessment method. The experiment has validated the initial hypothesis that the special online courses focused on honing foreign language skills and integrated in the domain of specific professional knowledge have a beneficial effect on students’ communicative competencies in general. There were identified the advantages of self-tuition based on Moodle platform. The Moodle course lets the teachers save considerable in-class time to focus more on communicative assignments. The findings of this study have a number of practical implications in ESP online courses development.

Full text
Abstract:
House flies (Muscadomestica) are global pests of animal agriculture, causing major annoyance, carrying pathogens among production facilities and humans and thus have profound impacts on animal comfort and productivity. Successful fly control requires an integrated pest management (IPM) approach that includes elements of manure management, mass trapping, biological control, and selective insecticide use. Insecticidal control of house flies has become increasingly difficult due to the rapidity with which resistance develops, even to new active ingredients. Global climate change poses additional challenges, as the efficacy of natural enemies is uncertain under the higher temperatures that are predicted to become more commonplace in the future. The two major objectives of this research project were: 1) to develop a cost-effective autodissemination application method of Pyriproxifen (PPF), an insect growth regulator, for controlling house flies; 2) to study the effect of increasing temperatures on the interactions between house flies and their principal natural enemies. First, we collected several wild house fly populations in both countries and established that most of them are susceptible to PPF, although one population in each country showed initial signs of PPF-resistance. An important finding is that the efficacy of PPF is substantially reduced when applied in cows’ manure. We also found that PPF is compatible with several common species of parasitoids that attack the house fly, thus PPF can be used in IPM programs. Next, we tried to develop “baited stations” in which house flies will collect PPF on their bodies and then deliver and deposit it in their oviposition sites (= autodissemination). The concept showed potential in lab experiments and in outdoor cages trials, but under field conditions the station models we tested were not effective enough. We thus tested a somewhat different approach – to actively release a small proportion of PPF-treated flies. This approach showed positive results in laboratory experiments and awaits further field experiments. On the second topic, we performed two experimental sets: 1) we collected house flies and their parasitoids from hot temperature and mild temperature areas in both countries and, by measuring some fitness parameters we tested whether the ones collected from hot areas are better adapted to BARD Report - Project 4701 Page 2 of 16 heat. The results showed very little differences between the populations, both of flies and parasitoids. 2) A “fast evolution” experiment, in which we reared house flies for 20 generations under increasing temperatures. Also here, we found no evidence for heat adaptation. In summary, pyriproxyfen proved to be a highly effective insect growth regulator for house flies that is compatible with it’s natural enemies. Although our autodissemination stations yielded disappointing results, we documented the proportion of flies in a population that must be exposed to PPF to achieve effective fly control. Both the flies and their principal parasitoids show no evidence for local adaptation to high temperatures. This is an encouraging finding for biological control, as our hypothesis was that the fly would be adapting faster to high temperatures than the parasitoids. BARD Report - Project 4701 Page 3 of 16

Full text
Abstract:
Develop an active air control system that, when installed on a turbocharged-engine system, will reduce NOX emissions below the levels of the system alone. While the turbocharged-engine system allows the natural gas compression industry to decrease pollutant emissions via increased air flow, the physics of the system and the environments in which these systems operate restrict further advancements. A new model, the Charge Air Integrated Manifold Engine Numerical Simulation (CAIMENS). The CAIMENS model was used to: Quantify the effects of charge air imbalance between cylinders in terms of NOX production; Illustrate that an imbalance in mass air flow creates a one-to-one imbalance in corrected trapped equivalence ratio Reveal a 5% to 12% imbalance in air flow present in the candidate Cooper GMV engine which correlated to a 65% to 92% imbalance in NOX production; and Provide detailed information that led to the specification of a mass air flow (MAF) sensor coupled with an air flow balancer (AFB), comprising the Active Air Control (AAC) system. The research team proceeded by working with the ERLE team to select cylinder liners for the NGML air flow bench, and then expanded the air flow bench from one cylinder to two cylinders. The specified AAC system was installed on each of the two cylinders. The research team then conducted a series of experiments to evaluate and fine tune the AAC system. The AAC system was able to correct up to a 12.4% air imbalance. The end point of the project was an AAC system that could, with some engineering effort, be applied to field engines. Benefit: The resulting technology was an active air flow control system consisting of an AFB integrated with a MAF sensor. The AFB has characteristics analogous to that of a throttle plate used in a carbureted internal combustion engine.

Full text
Abstract:
While modern overpass bridges are safe against collapse, their functionality will likely be compromised in case of design-level or beyond design-level earthquake, which may generate excessive residual displacements of the bridge deck. Presently, there is no validated, quantitative approach for estimating the operational level of the bridge after an earthquake due to the difficulty of accurately simulating residual displacements. This research develops a novel method for probabilistic evaluation of the post-earthquake functionality state of the bridge; the approach is founded on an explicit evaluation of bridge residual displacements and associated traffic capacity by considering realistic traffic load scenarios. This research proposes a high-fidelity finite-element model for bridge columns, developed and calibrated using existing experimental data from the shake table tests of a full-scale bridge column. This finite-element model of the bridge column is further expanded to enable evaluation of the axial load-carrying capacity of damaged columns, which is critical for an accurate evaluation of the traffic capacity of the bridge. Existing experimental data from the crushing tests on the columns with earthquake-induced damage support this phase of the finite-element model development. To properly evaluate the bridge's post-earthquake functionality state, realistic traffic loadings representative of different bridge conditions (e.g., immediate access, emergency traffic only, closed) are applied in the proposed model following an earthquake simulation. The traffic loadings in the finite-element model consider the distribution of the vehicles on the bridge causing the largest forces in the bridge columns.

Full text
Abstract:
In close cooperation with the Centro Sviluppo Materiali (CSM) and SNAM of Italy, with several years of support from the PRCI NG-18 committee, the Southwest Research Institute (SwRI) has developed and validated a "first principles" predictive model for ductile fracture in a gas transmission pipeline. In particular, the coordinated SwRI and CSM projects for the PRC -supplemented by work contributed by SNAM - has established a theoretically valid methodology and an accompanying line pipe material characterization procedure for gas industry use. This progress provides a theoretically sound framework for designing and operating gas transmission pipelines to be without risk of a large-scale ductile fracture event. However, there remained two important aspects of this technology that needed to be addressed before practical use of the methodology could be made by gas transmission companies. First, because the preceding projects concentrated on pipes with natural gas, to cover the full range of gas transmission pipeline service, the approach needed to be extended to include the effects of gases rich in hydrocarbons. Second, as the number of full-scale pipe fracture experiments that were included in the developmental phase of the research were limited, other data for validation of the model needed to be identified and employed. These two aspects of the ductile fracture methodology development process were conducted concurrently, and have now been completed. The progress that has been provided in detail in this report. The work is culminated by a relation through which the methodology can be applied by pipeline engineers to assess the possibility of a ductile fracture propagation. This report describes the development of a predictive model for ductile fracture in a gas transmission pipeline, thus providing a theoretically sound framework for designing and operating gas pipelines to be without risk of a large-scale ductile fracture event. The model represents an improvement on a number of empirical relations used in designing natural gas pipelines in that this model has been generalized to consider a wide-range of hydrocarbon contents and validated through both additional full-scale instrumented tests carried out by Centro Sviluppo Materiali of Italy and computer simulations conducted at Southwest Research Institute. Application of the model in pipeline design is based on determination of the maximum driving force for fracture, as described in the report, and contrasting this value with measured material resistance that provides a basis for assessing the likelihood of ductile fracture occurring. For existing pipelines the procedure can be used to obtain the maximum operating line pressure that will not put the pipeline at risk of ductile fracture.

Full text
Abstract:
The objective of the project was to develop a numerical model than may be used to predict the wrinkle formation and post formation behavior of a pipeline considering the effect of soil confinement and define the specifications for the development of a comprehensive wrinkle integrity assessment process. The result of this research is the development of wrinkle assessment techniques that could be used directly or could be used to codify maintenance guidelines. This project focused specifically on the pipe soil interaction modeling wrinkle formation as a result of the relative movement of the pipe and soil. The structural model developed and validated in this program and previous work could be applied to wrinkle bends, however, this issue is not specifically addressed in this report. In addition, the project development efforts focused on the monotonic soil interaction event of idealized (e.g., no secondary degradation like corrosion features) pipe segments. The project completed a critical review of existing structural and soil modelling techniques to identify the most suitable technologies for this application. The soil-pipe interaction under soil movement was found to be best represented using the LS-DYNA Multi-material Eulerian technique which permitted the application of a number of suitable soil constitutive models. This analysis tool permitted the consideration of a range of soil types and large soil displacements. Having defined the most suitable tool set, several pipe soil interaction models were developed. These models were used to illustrate the types of analyses that could be completed and the capabilities of the models to illustrate the sensitivity of the scenario loads, displacements to changes in soil, pipe and other parameters. The modeling results were discussed to demonstrate that their trends and results were in line with intuitive assumptions and engineering judgment. Additional models were developed to simulate large scale pipe-soil interaction laboratory test programs. The results of the simulated test programs were compared with the laboratory results as an initial validation of the modeling techniques and tools. The simulated soil displacement patterns, pipe strains and pipe displacement were shown to agree well with experimental results and as such illustrated the ability of the models to reproduce idealized pipe-soil interaction events. Full-scale soil displacement events were modeled to illustrate the application of the modeling tools to forecast or predict the effects of axial and transverse soil movements on buried pipeline segments. These results were used to illustrate the methods and assumptions inherent in the application of the modeling tools to predict soil loading on pipeline systems.

Full text
Abstract:
Fiber optic sensors have been under development in industrial and government laboratories around the world for over a decade. The commercial market for fiber sensors for measuring parameters such as temperature, displacement, and liquid level is now estimated to exceed $100 M/year. Aside from the commercial interest, the U. S. Department of Defense has vigorously pursued the development of fiber gyroscopes and hydrophones. In spite of the high level of research and development activity, however, until recently fiber sensors had not been successfully applied in high-temperature engine environments. The goal of this effort is to develop and test high-temperature fiber optic sensors and show that they are suitable for monitoring vibration and other instabilities in gas turbine engines. The underlying technology developed during the course of PRCI projects PR- 219-9120 and PR-219-9225 during 1991-94 serves as the foundation for PR-240-9416. Transducers with the fiber optic Fabry-Perot interferometer (FFPI) configuration have been adapted for use in the turbomachinery environment.To ensure the survival of the FFPI sensors at high temperatures, two techniques for coating the fibers with metal have been developed: electroplating and vacuum deposition. Coated sensors have subsequently been embedded in aluminum and brass alloys. Experiments on a small Sargent Welch turbine engine have shown the high sensitivity of embedded FFPI strain sensors to vibration in rolling bearings. Data have been collected in both the time and frequency domain. A new accelerometer design in which a metal-coated fiber containing the FFPI element is soldered directly to a diaphragm in a stainless steel housing shows response similar to a piezoelectric accelerometer in shaker table tests. The high sensitivity of the FFPI accelerometer has been demonstrated in field tests in a Solar Centaur turbine engine, and the design has survived temperatures greater than 500�C in a test oven. A magnetometer with a physical configuration similar to that of the accelerometer has been used to measure the distance from the sensor head to a rotating shaft made of ferromagnetic material. This device, which functions as a proximity probe, has been used to monitor shaft rotation rate (keyphasor application) and as a shaft thrust position sensor. These results indicate the potential for performing critical measurements in turbine engines with FFPI sensors. They can measure acceleration, distance (proximity), strain (as it relates to bearing defect diagnosis), and gas pressure, and can operate at higher temperatures than conventional transducers.
