Abstract:
The current study examines pre-modern and modern Japanese texts from the seventh ~ twentieth century, and documents the semantic and pragmatic change of ni-marked NPs, which include “dative subjects” and NPs which appear to refer to human referents. The data demonstrates that what are called “dative subjects” in modern Japanese are diachronically and synchronically related to the most prototypical meaning/usage of ni-marked NPs as a spatial framework. The original function underwent changes from more propositional to more subjective usages — from its most basic usage, indicating stative locations, to its metonymic usage, marking locations where individuals worthy of respect reside so as to avoid their explicit mention, and finally to its extended usage, indicating human referents. This extended usage further developed into a subjective framework for propositions in contemporary Japanese novels written in the first person perspective. This shift from propositional to expressive/subjective usages is not binary, but rather continual, and the transition from one usage to another involves each new usage coexisting with the prior ones.

This article reports on that part of a research study conducted to answer two main questions. First, what is the spatial pattern of internet usage among users aged 25 to 40 in Tehran? Second, how has this pattern changed over time, from the beginning of internet usage to the time of the research? The study was designed and executed using descriptive and qualitative methods, and the relevant data were collected through in-depth interviews with a selected sample of 15 individuals from the target population, specifically the first generation of internet users in Tehran. The findings indicate that the spatial pattern of internet usage has shifted from initially being in the order of usage at educational institutions, residence, internet cafes, and workplaces, to a new order of usage at workplaces, residences, educational institutions, friends' homes, and internet cafes.

Abstract:
Energy usage in cities is intertwined with its spatial configuration—the denser and more compact the city, the more concentrated and efficient the energy usage is to be expected. To achieve sustainable communities, cities (and their inhabitants) must reconsider its spatial configurations in the context of rapid urbanisation and growth in light of limited resources and conflicting spatial claims. This article seeks to understand how spatial configurations affect transport energy usage in cities and propose an integrated assessment approach factoring spatial configurational analysis in relation to transport energy usage at the micro- and macroscale. Comparing Bergen, Norway, and Zürich, Switzerland, findings showed that spatial configurations were positively correlated to transport energy usage. Street structures suitable for walking and less suitable for car traffic tended to exhibit lower amounts of energy usage. Following this, nine typologies of transport and land use patterns are described to support planning for more sustainable means of transport.

Abstract:
The rapid development in East Jakarta City has led to increased land requirements and causes unalignment of land use. Research objective are to analyze the alignment of spatial usage with the spatial plan and its control in East Jakarta City. The research methods used are spatial analysis based on image interpretation and Geographic Information System, descriptive statistic for seeking influence factors, description analysis for spatial control usage and its guidance. Results analysis for 6 (six) existing land use showed that alignment of existing land use has area of 12.430,5 ha or 76.5 % and unalignment of existing land use has area 3.812,7 ha or 23.5%. Factors that influence unalignment of existing land use, namely economic needs, housing needs, distance from the economic center, distance from the road, lack of socialization to the community, population density and the presence of public facilities. Analysis of the implementation of spatial usage control shows that the East Jakarta City Government has implemented 4 spatial usage control instruments namely the Spatial Detail Plan along with its Zoning Regulations, licensing, providing incentives and disincentives and sanctions but the implementation is still considered not maximally. Directives for improving spatial usage are carried out by maximizing and improving the implementation of four instruments for controlling spatial usage.

Abstract:
This study presents an approach to collect and classify usage data of public charging infrastructure in order to predict usage based on socio-demographic data within a city. The approach comprises data acquisition and a two-step machine learning approach, classifying and predicting usage behavior. Data is acquired by gathering information on charging points from publicly available sources. The first machine learning step identifies four relevant usage patterns from the gathered data using an agglomerative clustering approach. The second step utilizes a Random Forest Classification to predict usage patterns from socio-demographic factors in a spatial context. This approach allows to predict usage behavior at locations for potential new charging points. Applying the presented approach to Munich, a large city in Germany, results confirm the adaptability in complex urban environments. Visualizing the spatial distribution of the predicted usage patterns shows the prevalence of different patterns throughout the city. The presented approach helps municipalities and charging infrastructure operators to identify areas with certain usage patterns and, hence different technical requirements, to optimize the charging infrastructure in order to help meeting the increasing demand of electric mobility.

Abstract:
Spatial perception in virtual reality systems relies on a number of variables, including how users explore, observe and perceive the spatial factors of a virtual environment. In virtual reality systems, users can assume different types of views for spatial decision-making about the sizes and scales of and relationships among virtual spaces. This research explored the role of view usage patterns in spatial cognition and decision-making in a fully immersive virtual reality system and monitor-based virtual reality system. The focus of study was the impact of using the eye-level view as the only view type in a fully immersive virtual reality system on actual and perceived view usage patterns in a monitor-based virtual reality system. In addition, users’ spatial decision-making results were compared with regards to system usage sequence and view type. Quantitative and qualitative data, descriptive and inferential statistical comparisons, and testing of both systems were used to determine the participants’ performances concerning view usage patterns and the design outcomes. The results showed a moderate association between the view type utilized for spatial perception in a monitor-based virtual reality system and variations in system usage sequence. In addition, for both systems, variations in system usage sequence, space type, and other characteristics all affected the strength of the linear regressions of the sizes and scales of the design outcomes.

Abstract:
Ce travail de thèse concerne la formulation et la mise en œuvre d'un ensimage thermoplastique, respectueux de l'environnement et utilisable à une échelle industrielle. La première étape du projet a été d'adapter les moyens et les ingrédients de formulation aux contraintes industrielles. La formule d'ensimage est basée sur une dispersion aqueuse de particules de polymère thermoplastique (PEI) obtenue par la technique d'émulsion/évaporation. Le choix de la technique de dispersion et du solvant volatil ont été les premières modifications apportées à la formulation d'ensimage qui existait à l'échelle laboratoire. Une optimisation de la dispersion aqueuse a été nécessaire pour répondre aux contraintes industrielles de stabilité, de température et de mise en œuvre. La seconde étape a été l'optimisation de la dispersion aqueuse d'ensimage par une modélisation prédictive puis sa validation expérimentale. L'étude prédictive (QSPR) a permis de se focaliser sur deux paramètres essentiels influençant la stabilité de la dispersion : la vitesse d'émulsification et la concentration en tensioactif. La validation expérimentale nous a permis de confirmer l'importance de ces paramètres et ainsi mieux maîtriser l'élaboration des dispersions. Afin de répondre aux exigences industrielles, notamment en termes de comportement rhéologique, une nouvelle formule d'ensimage a été élaborée. Cette dernière met à profit le comportement viscoélastique de tubules formés par l'association CTAC/acide salicylique, pour préparer des dispersions aqueuses stables. Il s'agit là du premier exemple d'utilisation de tubules pour disperser dans l'eau des particules de polymère par la technique d'émulsion/évaporation. La stabilité de la dispersion a été mesurée à 22h et les propriétés de la dispersion permettent une redispersion aisée de la formulation même après déstabilisation. Enfin cette dispersion d'ensimage a fait l'objet de tests laboratoires et pilotes pour réaliser, respectivement, un film sur plaques de graphite et un ensimage sur fibres de carbone HexTow(r) IM7 sur la chaîne d'ensimage de notre partenaire industriel. Les résultats ont montré un ensimage abondant et qui montrait de bonnes propriétés d'adhésion dans le matériau composite final. Cette dispersion d'ensimage a été brevetée par Airbus Defence &amp; Space<br>This PhD project is related to the development of an eco-friendly thermoplastic sizing formulation and its implementation as sizing, usable at an industrial scale. The first step of the project was to adjust the preparation and the ingredients of this formulation to the industrial requirements. The sizing formulation is based on an aqueous dispersion of thermoplastic polymer particles (PEI) obtained by an emulsion/solvent evaporation process. The choice of the dispersion method and the volatile solvent were the first modifications achieved on the sizing formulation which was available at a laboratory scale. An optimization of the aqueous dispersion was necessary to meet the industrial requirements of stability, temperature and implementation. The second step was the optimization of the aqueous sizing dispersion by a predictive model, and then its experimental validation. The predictive study (QSPR) permitted to focus on two essential parameters affecting the stability of the dispersion: the stirring speed and the surfactant concentration. The experimental validation permitted to confirm the importance of these parameters and consequently a better understanding of the dispersion process. In order to satisfy the industrial requirements, especially in terms of rheological behavior, a new sizing formulation was elaborated. This latter takes advantage of the visco-elastic behavior of the tubules formed by the association CTAC / salicylic acid, to formulate stable aqueous dispersions. This is the first example of use of tubules to disperse polymer particles in water by emulsion/solvent evaporation process. The stability of dispersion was measured to 22 hours and the proprieties of this dispersion permit an easy redispersion of formulation even after destabilization. Finally, this sizing dispersion was tested in laboratory and industry to make, respectively, film on carbon slab and sizing on carbon fibers HexTow(r) IM7 using industrial sizing means. The results showed an abundant sizing and good adhesion properties in the final composite material. This sizing dispersion was patented by Airbus Defence &amp; Space

Abstract:
Comprendre et modéliser le comportement des matériaux sous irradiation électronique est un enjeu important pour l’industrie spatiale. La fiabilité des satellites nécessite de maîtriser et prédire les potentiels de surface s'établissant sur les diélectriques. Ce travail de doctorat a donc pour objectif de caractériser et de modéliser les différents mécanismes physiques (en surface et en volume) gouvernant le potentiel de charges dans les matériaux polymères spatiaux tels que le Téflon® FEP et le Kapton® HN. La mise au point d'un nouveau dispositif et d'un protocole expérimental a permis de corroborer l'existence d’une conductivité latérale des charges, souvent négligée dans les modèles physiques et numériques. Les études paramétriques, révélant l’influence de l’énergie et le flux des électrons incidents, ont permis de brosser un portrait des processus mis en jeu pour le transport (par saut ou par piégeage/dépiégeage) de charges en surface. A la lumière de cette étude, une conductivité équivalente est extraite, assimilant le matériau à un système prenant en compte les mécanismes de transport volumique et surfacique. L'analyse des évolutions non-monotones de potentiel mesurées sur les polymères spatiaux en condition spatiale a permis de révéler une dépendance de la conductivité volumique induite sous irradiation avec la dose reçue. L'étude paramétrique réalisée sur les mécanismes de transport en volume révèle une influence minoritaire du déplacement du barycentre de charges et du vieillissement physicochimique. Un modèle «0D» à un seul niveau de pièges, prenant en compte les mécanismes de piégeage/dépiégeage et recombinaison entre les porteurs de charges, a été développé. Ce modèle simplifié permet de reproduire qualitativement les évolutions de potentiel expérimentales en fonction du débit de dose et lors d'irradiations successives<br>Charging behaviours of space dielectric materials, under electron beam irradiation, is of special interest for future spacecraft needs, since this mechanism could induce electrostatic discharges and consequently damages on the sensitive systems on board. In order to assess the risks of charging and discharging, this work aims at understanding the overall charge transport mechanisms and predicting the electrical behaviour of the insulator materials, especially Teflon® FEP and Kapton® HN. For an optimized prediction, the first part of our work is thus to check whether lateral conduction process can take place in the overall charge transport mechanism. Through the definition of a new experimental set-up and protocol, we have been able to discriminate between lateral and bulk conductivity and to reveal the presence of lateral conductivity that is enhanced by radiation ionization processes. We have been able to demonstrate as well that lateral intrinsic conductivity is enhanced with the increase current density and when approaching the sample surface. The second part of our work deals with the characterization of the electrical charging behaviour of Teflon® FEP under multi-energetic electron beam irradiation and the modelling of the overall bulk charge transport mechanisms. An experimental study on charge potential evolution as a function of electron spectrum, electric field, relaxation time, dose and dose rate, was performed. A numerical model has been developed to describe the effect of the different abovementioned mechanisms on the evolution of the surface potential. This model agrees correctly with the experimental phenomenology at qualitative level and therefore allows understanding the physical mechanisms steering charge transport in Teflon® and Kapton®

Full text
Abstract:
Les systèmes Spatial On-Line Analytical Processing (SOLAP) permettent de prendre en charge l’analyse multidimensionnelle en ligne d’un très grand volume de données ayant une référence spatiale. Dans ces systèmes, le vague spatial n’est généralement pas pris en compte, ce qui peut être source d’erreurs dans les analyses et les interprétations des cubes de données SOLAP, effectuées par les utilisateurs finaux. Bien qu’il existe des modèles d’objets ad-hoc pour gérer le vague spatial, l’implantation de ces modèles dans les systèmes SOLAP est encore à l’état embryonnaire. En outre, l’introduction de tels modèles dans les systèmes SOLAP accroit la complexité de l’analyse au détriment de l’utilisabilité dans bon nombre de contextes applicatifs. Dans cette thèse nous nous proposons d’investiguer la piste d’une nouvelle approche visant un compromis approprié entre l’exactitude théorique de la réponse au vague spatial, la facilité d’implantation dans les systèmes SOLAP existants et l’utilisabilité des cubes de données fournis aux utilisateurs finaux.Les objectifs de cette thèse sont donc de jeter les bases d’une approche de conception de cube SOLAP où la gestion du vague est remplacée par la gestion des risques de mauvaises interprétations induits, d’en définir les principes d’une implantation pratique et d’en démontrer les avantages.En résultats aux travaux menés, une approche de conception de cubes SOLAP où le risque de mauvaise interprétation est considéré et géré de manière itérative et en adéquation avec les sensibilités des utilisateurs finaux quant aux risques potentiels identifiés a été proposée; des outils formels à savoir un profil UML adapté, des fonctions de modification de schémas multidimensionnels pour construire les cubes souhaités, et un processus formel guidant de telles transformations de schémas ont été présentés; la vérification de la faisabilité de notre approche dans un cadre purement informatique avec la mise en oeuvre de l’approche dans un outil CASE (Computed Aided Software Engineering) a aussi été présentée. Pour finir, nous avons pu valider le fait que l’approche fournisse non seulement des cubes aussi compréhensibles et donc utilisables que les cubes classiques, mais aussi des cubes où le vague n’est plus laissé de côté, sans aucun effort pour atténuer ses impacts sur les analyses et les prises de décision des utilisateurs finaux<br>SOLAP (Spatial On-Line Analytical Processing) systems support the online multi-dimensional analysis of a very large volume of data with a spatial reference. In these systems, the spatial vagueness is usually not taken into account, which can lead to errors in the SOLAP datacubes analyzes and interpretations end-users make. Although there are ad-hoc models of vague objects to manage the spatial vagueness, the implementation of these models in SOLAP systems is still in an embryonal state. In addition, the introduction of such models in SOLAP systems increases the complexity of the analysis at the expense of usability in many application contexts. In this thesis we propose to investigate the trail of a new approach that makes an appropriate compromise between the theoretical accuracy of the response to the spatial vagueness, the ease of implementation in existing SOLAP systems and the usability of datacubes provided to end users.The objectives of this thesis are to lay the foundations of a SOLAP datacube design approach where spatial vagueness management in itself is replaced by the management of risks of misinterpretations induced by the vagueness, to define the principles of a practical implementation of the approach and to demonstrate its benefits.The results of this thesis consist of a SOLAP datacube design approach where the risks of misinterpretation are considered and managed in an iterative manner and in line with the end users tolerance levels regarding those risks; formal tools namely a suitable UML (Unified Modeling Language) profile, multidimensional schemas transformation functions to help tailored the datacubes to end-users tolerance levels, and a formal process guiding such schemas transformation; verifying the feasibility of our approach in a computing context with the implementation of the approach in a CASE (Computed Aided Software Engineering) tool. Finally, we were able to validate that the approach provides SOLAP datacubes that are not only as comprehensible and thus usable as conventional datacubes but also datacubes where the spatial vagueness is not left out, with no effort to mitigate its impacts on analysis and decision making for end users

Abstract:
The spatial characterization of Puerto Rican commercial fisheries describing fishing gear use in relation to habitat classes and bathymetry ranges was achieved through the collection and analysis of spatial fisheries data. An extensive field data gathering session was conducted in the entire Puerto Rican territory during the summer months of 2009, from June to October. The field data was digitized and analyzed using geographic information systems (GIS) and computer spreadsheet software, and gear usage charts and graphs, fishing grounds maps, and fishing intensity maps were produced for four gear categories: line, net, dive, and trap gears. Patterns and evidence of likely relationships linking gear usage and benthic habitat, and between gear utilization and water depth ranges, were presented. The importance of the spatial characterization of the commercial fishery for Puerto Rican fisheries management, and other recommendations were given within the concluding chapter.

Abstract:
Motivés par des exigences de sécurité internationale, les Etats fournisseurs de hautes technologies élaborent au sein de l’Arrangement de Wassenaar un contrôle des exportations des produits duaux, dont les principes sont repris aux niveaux nationaux. L’analyse des règlementations de l’Union Européenne et des Etats-Unis révèle l’impact que les contrôles ont sur la sécurité et le commerce : ils ne cessent d’osciller entre préservation des intérêts étatiques et protection des intérêts commerciaux. Ces contrôles sont en effet perçus comme une contrainte par les exportateurs aérospatiaux mondiaux en tant qu’entrave au principe de libre-circulation. Face à une compétitivité internationale accrue, les industriels aspirent à une facilitation de leurs échanges par le biais d’un allègement des modalités de contrôle et par la mise en place d’une certification des entreprises destinataires de produits duaux. Cette tentative de responsabilisation industrielle risque toutefois de porter atteinte à l’objectif de sécurité des contrôles du fait de la déresponsabilisation étatique qu’elle entraîne dans un domaine régalien. Dès lors, il est essentiel de s’interroger sur l’orientation que vont prendre ces régimes encore en cours d’élaboration: alors que la liberté de circulation semble avoir été privilégiée jusqu’à ce jour, le nouveau contexte conjoncturel lié à la crise économique pourrait changer la donne. Les principes libéraux semblant laisser place à des considérations plus protectionnistes, il est plausible que les Etats s’investissent désormais davantage dans le contrôle d’exportation des biens duaux et utilisent cet instrument pour relancer leur économie<br>For peace and international security reasons, high technology supplier states are developing through the Wassenaar Arrangement a system of export controls for dual use (military and civil) goods and technologies, the principles of which are to be followed at a national level. The analysis of the regulations of the European Union and the United States shows the impact of these controls on security and trade. Since their creation, these systems have been balancing between the preservation of state interests and the protection of trade interests. Export controls are regarded as a constraint by world companies because they are an obstacle to free trade. Faced with increasing international competition, exporters want their exchanges to be simplified by the means of a reduction of the measures of control, and through the implementation of a certification of recipient companies of dual use products. However, this attempt to give responsabilities to companies may go against the security target of export controls, because it is likely to involve a loss of responsability in these states' areas. Thus, this study will examine the direction that export controls will take : althrough free trade seems to have been favoured until now, the new international financial and economic context may involve a new deal. As free-market principles seem to give way to more protectionist considerations, States are bound to invest more in the export controls of dual use goods, and use this formidable tool in order to boost their economy

Abstract:
This dissertation aims to develop methods for statistical predictions based on various types of data from different areas. We focus on applications from reliability and spatial epidemiology. Chapter 1 gives a general introduction of statistical predictions. Chapters 2 and 3 investigate the photodegradation of an organic coating, which is mainly caused by ultraviolet (UV) radiation but also affected by environmental factors, including temperature and humidity. In Chapter 2, we identify a physically motivated nonlinear mixed-effects model, including the effects of environmental variables, to describe the degradation path. Unit-to-unit variabilities are modeled as random effects. The maximum likelihood approach is used to estimate parameters based on the accelerated test data from laboratory. The developed model is then extended to allow for time-varying covariates and is used to predict outdoor degradation where the explanatory variables are time-varying. Chapter 3 introduces a class of models for analyzing degradation data with dynamic covariate information. We use a general path model with random effects to describe the degradation paths and a vector time series model to describe the covariate process. Shape restricted splines are used to estimate the effects of dynamic covariates on the degradation process. The unknown parameters of these models are estimated by using the maximum likelihood method. Algorithms for computing the estimated lifetime distribution are also described. The proposed methods are applied to predict the photodegradation path of an organic coating in a complicated dynamic environment. Chapter 4 investigates the Lyme disease emergency in Virginia at census tract level. Based on areal (census tract level) count data of Lyme disease cases in Virginia from 1998 to 2011, we analyze the spatial patterns of the disease using statistical smoothing techniques. We also use the space and space-time scan statistics to reveal the presence of clusters in the spatial and spatial/temporal distribution of Lyme disease. Chapter 5 builds a predictive model for Lyme disease based on historical data and environmental/demographical information of each census tract. We propose a Divide-Recombine method to take advantage of parallel computing. We compare prediction results through simulation studies, which show our method can provide comparable fitting and predicting accuracy but can achieve much more computational efficiency. We also apply the proposed method to analyze Virginia Lyme disease spatio-temporal data. Our method makes large-scale spatio-temporal predictions possible. Chapter 6 gives a general review on the contributions of this dissertation, and discusses directions for future research.<br>Ph. D.

Abstract:
The article first discusses definitions of the term dualism on the basis of its usage in modern scholarship, including a taxonomy of various types of dualistic oppositions in early Jewish and early Christian texts. In the second section, the author provides a brief sketch of the application of the term in Johannine studies, especially in the Bultmann school and in the debate on the influence of Qumran texts and ideas. He then describes various elements of dualistic language in the Gospel and the Epistles of John, including names of eschatological opponents, the spatial categories of above and below, the metaphoric language of light and darkness, the notion of a final eschatological destiny of life or death, and the opposition of the community and the world. On the basis of those observations, the function of the dualistic language elements in the Gospel and Epistles of John is determined.

Abstract:
Buddhism is flourishing on the Internet and digital media. However, the form and usage patterns of Buddhist media technologies have varied considerably from the earliest oral texts to the latest online versions of the Buddhist canon. Do such media transformations merely transmit the old dharma in a new bottle, or do they change Buddhism’s message? Are these changes to be welcomed or shunned? This chapter explores how various media technologies tend to promote particular aspects of Buddhism, and also how different Buddhist worldviews shape how these media are used. First, it sketches a short genealogy of Buddhist media technologies. Second, it concentrates on contemporary digital media, briefly describing Buddhist bulletin boards, email lists, websites, computer apps, virtual worlds, and video games. Third, the chapter explains digital media’s procedural, participatory, encyclopedic, and spatial affordances. Finally, it illuminates how digital media affordances are shaped by the technological worldview of convert Buddhism.

Abstract:
Contested sacred sites pose a difficult challenge in the field of toleration. Holy sites are often at the center of intense contestation between different groups regarding a wide variety of issues, including ownership, access, usage rights, permissible religious conduct, and many other aspects. As such, they are often the source of immense levels of violence, and intractable, long-standing conflicts. Governing the Sacred profiles five central contested sacred sites which exemplify the immense difficulties associated with such sites: Devils Tower National Monument (Wyoming, U.S.), Babri Masjid/Ram Janmabhoomi (Uttar-Pradesh, India), the Western Wall (Jerusalem), the Church of the Holy Sepulchre (Jerusalem), and the Temple Mount/Haram esh-Sharif (Jerusalem). The in-depth, contextual and casuistic study of these sites, which differ in spatial, cultural, and religious settings, enables the construction of a novel, critical typology of five corresponding models or ways of governing the sacred. By telling the fascinating stories of five high-profile contested sacred sites, Governing the Sacred develops and critically explores five different models of governing contested sacred sites: “non-interference,” “separation and division,” “preference,” “status quo,” and “closure.” Each model, in turn, relies on different sets of considerations, central among them trade-offs between religious liberty and social order. Beyond its scholarly contribution, the novel typology developed in Governing the Sacred aims to assist democratic governments in their attempt to secure public order and mutual toleration among opposed groups in contested sacred sites.

Abstract:
AbstractThe residential architecture in the process of urban digital development has become a living complex with real and virtual mirrors, in which people are the unity of connection between spatial environment, identity and living relationship. In this paper, the new value orientation of community residential design is analyzed by sorting out the meaning of community; within the design system of residential space, the intimacy and public consciousness of residents’ neighborhood relationship is enhanced through spatial transition and cultivation of shared living space. The argument is developed from three levels: individual residents’ self-reconstruction, residents’ new behavioral decisions, and spatial behavioral output. Through a series of argumentation, the relationship between community and residential space planning and design is explored, and the data on the interaction between users, usage behavior and space usage of different households are statistically obtained. At the same time, this paper simulates and designs the community residential space module system based on this data and combined with the computer 3D model derivation. The residential block formed by the combination of the smallest modules, as the smallest residential unit, continues to form the design path of a sustainable residential system through the process of combination and deformation of space.

Abstract:
AbstractIncreasingly visible migrant communities that coexist within transnational spaces (Vertovec, 2009) are part of a contemporary world marked by a changing political approach to immigration, in which integration is the key word. The vagueness of the term (Schinkel, 2017) is compensated by the potential benefits derived from its usage. Given its multidimensionality (Harder et al., 2018; Voicu &amp; Vlase, 2014), integration allows observing a liquid migration. The term was developed in relation to intra-European migration (Engbersen, 2018), to stress the encapsulation of such spatial movement into a more complex set of social changes, and to stress the flexibility of migration itself. Such fluidity implies a series of temporary states in the personal life, that is appropriate for the case of high-skilled intra-European migrants.

Full text
Abstract:
This Coastal and Hydraulics Engineering Technical Note (CHETN) describes the design and implementation of a wave model evaluation system, altWIZ, which uses wave height observations from operational satellite radar altimeters. The altWIZ system utilizes two recently released altimeter databases: Ribal and Young (2019) and European Space Agency Sea State Climate Change Initiative v.1.1 level 2 (Dodet et al. 2020). The system facilitates model evaluation against 1 Hz1 altimeter data or a product created by averaging altimeter data in space and time around model grid points. The system allows, for the first time, quantitative analysis of spatial model errors within the U.S. Army Corps of Engineers (USACE) Wave Information Study (WIS) 30+ year hindcast for coastal United States. The system is demonstrated on the WIS 2017 Atlantic hindcast, using a 1/2° basin scale grid and a 1/4° regional grid of the East Coast. Consistent spatial patterns of increased bias and root-mean-square-error are exposed. Seasonal strengthening and weakening of these spatial patterns are found, related to the seasonal variation of wave energy. Some model errors correspond to areas known for high currents, and thus wave-current interaction. In conjunction with the model comparison, additional functions for pairing altimeter measurements with buoy data and storm tracks have been built. Appendices give information on the code access (Appendix I), organization and files (Appendix II), example usage (Appendix III), and demonstrating options (Appendix IV).

Abstract:
Active transportation can play an important role in promoting more physically active and positive public health outcomes. While walking and biking provide significant physical health benefits, their modal share remains low. As a new form of micromobility service, shared e-scooters can enhance the suite of options available in cities to promote active transportation and fill in the gaps when walking or biking are not preferred. Although e-scooters show potential as a mode of transportation, it is unclear whether people will adopt the technology for everyday use. Furthermore, shared micromobility (e.g., electric scooters) is gaining attention as a complementary mode to public transit and is expected to offer a solution to access/egress for public transit. However, few studies have analyzed integrated usage of shared e-scooters and public transit systems while using panel data to measure spatial and temporal characteristics. This study aims to examine the adoption and frequency of shared e-scooter usage and provide policy implementation. To do so, the researchers launched a survey in the Chicago region in late 2020 and collected a rich data set that includes residents’ sociodemographic details and frequency of shared e-scooter use. To characterize the frequency, the researchers used an ordered probit structure. The findings show that respondents who are male, low income, Millennials and Generation Z, or do not have a vehicle are associated with a higher frequency of shared e-scooter use. Furthermore, this study utilizes shared e-scooter trips for a 35-day measurement period from 10 shared e-scooter operators in Chicago, where the researchers used a random-parameter negative binomial modeling approach to analyze panel effects. The findings highlight the critical role of spatial and temporal characteristics in the integration of shared e-scooters with transit.

Full text
Abstract:
Autonomous marine vehicles (AMVs) are typically deployed for long periods of time in the ocean to monitor different physical, chemical, and biological processes. Given their limited energy budgets, it makes sense to consider motion plans that leverage the dynamics of the surrounding flow field so as to minimize energy usage for these vehicles. In this paper, we present two graph search based methods to compute energy optimal paths for AMVs in two-dimensional (2-D) time-varying flows. The novelty of the proposed algorithms lies in a unique discrete graph representation of the 3-D configuration space spanned by the spatio-temporal coordinates. This enables a more efficient traversal through the search space, as opposed to a full search of the spatio-temporal configuration space. Furthermore, the proposed strategy results in solutions that are closer to the global optimal when compared to greedy searches through the spatial coordinates alone. We demonstrate the proposed algorithms by computing optimal energy paths around the Channel Islands in the Santa Barbara bay using time-varying flow field forecasts generated by the Regional Ocean Model System. We verify the accuracy of the computed paths by comparing them with paths computed via an optimal control formulation.

Full text
Abstract:
US Army Corps of Engineers (USACE) reservoir projects significantly alter river ecosystem structure and function. Each project adheres to a defined set of operating rules to achieve primary objectives, which typically include flood risk management, hydropower, or navigation along with ancillary objectives for drinking water/irrigation, recreation, and natural resources management. Environmental flows (E-Flows) planning under the Sustainable Rivers Program has demonstrated new opportunities for environmental pool management (EPM; Theiling et al. 2021a, 2021b) that have no negative impact on other reservoir functions. In some locations, water level drivers can be managed to improve ecological outcomes, like wetlands, waterbirds, reptiles, and water quality, by altering the magnitude, timing, frequency, and duration of pool level changes that affect riparian and shoreline plant communities. Reservoirs with large delta areas may provide particularly important wetland or riparian habitat management along avian migratory pathways or in wildlife conservation regions (Johnson 2002). These large deltas can be identified and characterized using available satellite imagery, which along with water level habitat drivers available in hydrology databases, can be used to identify USACE reservoirs with good potential for EPM. A spatial analysis of USACE reservoirs capable to support EPM can be developed utilizing estimates of water occurrence, transition, and seasonality as well as surface elevation data derived from satellite imagery to assess geomorphology drivers. USACE water management records can be used to assess wetland drivers. Nationwide screening will be broken down into ecoregions to establish the anticipated geographic range of variation for wetland and riparian habitat drivers. Southwestern US reservoirs, for example, will have much different hydrology and fauna than Midwest and Eastern US reservoirs.

Abstract:
The U.S. Army Corps of Engineers (USACE) construction projects have multiple stakeholders that collaborate with project delivery team members during the execution of these projects. Many of these stakeholders are located across the U.S., which makes virtual interactions a common communication method for these teams. These interactions often lack spatial visualization, which can add complications to the progress reports provided and how the information is received/interpreted. The visualization of project progress and documents would be invaluable to the stakeholders on critical projects constructed by the USACE. This research was conducted to determine alternatives for migrating Resident Management System (RMS) data into a portal web viewer. This report provides proposed solutions to creating these links in efforts to better harmonize data management and improve project presentation.

Full text
Abstract:
The US Army Corps of Engineers (USACE) is responsible for maintaining safe and navigable waterways through the periodic dredging of shoaled sediment from federal navigation channels. While dredging, a portion of the bottom sediments become resuspended creating a sediment plume near the dredging operation. Suspension of sediments during dredging and dredged sediment disposal operations continues to be a primary concern of regulatory agencies charged with the protection of environmental resources. Consequently, almost all dredging projects incorporate some level of regulatory compliance monitoring dedicated to measuring sediment resuspension. For numerous reasons the conventional approach using manned surface vessels to perform compliance monitoring is frequently ineffective in both adaptively managing dredging projects and ensuring true environmental protection. Advancements in unmanned platforms and payload technologies offer new and potentially more robust alternatives to conventional platforms. In this study, the use of unmanned aerial system (UAS) and weather balloon mounted camera imagery was demonstrated, and the use of an unmanned surface vessel (USV) to monitor turbidity in navigation channels and near a dredging operation. The imagery from the UAS and weather balloon were compared to in-situ turbidity measurements in a turbid distributary channel and near a dredging operation, while the USV was used to learn more about in-situ turbidity associated with passing vessels in a navigation channel. The results of the demonstrations show the unmanned technology bundled with off-the-shelf payloads can help to produce evidence-based information through easily interpreted aerial imagery and in situ measurements which can help to inform and manage water quality in areas where sediment plumes are an environmental concern.

Abstract:
The Everglades National Park and Big Cypress National Preserve vegetation mapping project is part of the Comprehensive Everglades Restoration Plan (CERP). It is a cooperative effort between the South Florida Water Management District (SFWMD), the United States Army Corps of Engineers (USACE), and the National Park Service’s (NPS) Vegetation Mapping Inventory Program (VMI). The goal of this project is to produce a spatially and thematically accurate vegetation map of Everglades National Park and Big Cypress National Preserve prior to the completion of restoration efforts associated with CERP. This spatial product will serve as a record of baseline vegetation conditions for the purpose of: (1) documenting changes to the spatial extent, pattern, and proportion of plant communities within these two federally-managed units as they respond to hydrologic modifications resulting from the implementation of the CERP; and (2) providing vegetation and land-cover information to NPS park managers and scientists for use in park management, resource management, research, and monitoring. This mapping project covers an area of approximately 7,400 square kilometers (1.84 million acres [ac]) and consists of seven mapping regions: four regions in Everglades National Park, Regions 1–4, and three in Big Cypress National Preserve, Regions 5–7. The report focuses on the mapping effort associated with the Northwest Coastal Everglades (NWCE), Region 4 , in Everglades National Park. The NWCE encompasses a total area of 1,278 square kilometers (493.7 square miles [sq mi], or 315,955 ac) and is geographically located to the south of Big Cypress National Preserve, west of Shark River Slough (Region 1), and north of the Southwest Coastal Everglades (Region 3). Photo-interpretation was performed by superimposing a 50 × 50-meter (164 × 164-feet [ft] or 0.25 hectare [0.61 ac]) grid cell vector matrix over stereoscopic, 30 centimeters (11.8 inches) spatial resolution, color-infrared aerial imagery on a digital photogrammetric workstation. Photo-interpreters identified the dominant community in each cell by applying majority-rule algorithms, recognizing community-specific spectral signatures, and referencing an extensive ground-truth database. The dominant vegetation community within each grid cell was classified using a hierarchical classification system developed specifically for this project. Additionally, photo-interpreters categorized the absolute cover of cattail (Typha sp.) and any invasive species detected as either: Sparse (10–49%), Dominant (50–89%), or Monotypic (90–100%). A total of 178 thematic classes were used to map the NWCE. The most common vegetation classes are Mixed Mangrove Forest-Mixed and Transitional Bayhead Shrubland. These two communities accounted for about 10%, each, of the mapping area. Other notable classes include Short Sawgrass Marsh-Dense (8.1% of the map area), Mixed Graminoid Freshwater Marsh (4.7% of the map area), and Black Mangrove Forest (4.5% of the map area). The NWCE vegetation map has a thematic class accuracy of 88.4% with a lower 90th Percentile Confidence Interval of 84.5%.
