Texte intégralRésumé :
The limitations of traditional methods of providing long-term creep design data are discussed in relation to existing national and international testing standards, current parametric procedures for extrapolation of stress-rupture values and the factors affecting the high degree of scatter in conventional long-term property sets for widely-used structural steels. These deficiencies may be overcome by adopting an alternative data acquisition methodology based on the analysis of short-term high-precision constant-stress creep curves.

Texte intégralRésumé :
This study investigates the impact of Verizon Communications Inc.'s acquisition of Yahoo on the company's stock performance, using a combination of statistical, visual, and multiscale analytical methods. The research analyzes how strategic corporate decisions, particularly acquisitions, influence short-term and long-term stock behavior. Data spanning from 2014 to 2024 was analyzed to capture pre-acquisition, acquisition, and post-acquisition trends. The methodology integrates boxplot visualizations to explore variability and outliers, quantile analysis to assess distributional characteristics, and descriptive statistics to summarize key metrics such as mean, standard deviation, skewness, and kurtosis. Tabulation analysis evaluates associations between stock returns and trading volumes, while wavelet analysis decomposes stock returns into multiple time scales to identify short-term fluctuations and long-term trends. Results reveal significant volatility during key events, such as the Yahoo acquisition in 2017 and the COVID-19 pandemic, with daily fluctuations peaking at ±6. Medium-term adjustments (4–8 days) exhibited moderate changes, and long-term trends (32-day cycles) showed structural shifts, including positive coefficients in 2017 (+0.5) and negative coefficients in 2020 (-0.6). The research highlights the heavy-tailed nature of return distributions and skewed trading volume patterns. This study provides insights into the multifaceted effects of acquisitions on stock performance, offering valuable implications for investors and corporate managers in optimizing strategic decisions.

Texte intégralRésumé :
Purpose This paper aims to focus on Tata Motors, an automobile company from an emerging market, and its successful acquisition of two global marquee car brands in Jaguar and Land Rover (JLR). It traces the evolution of JLR under the stewardship of Tata Motors over an eight-year long period and examines the strategic reasons for the success of the acquisition. Design/methodology/approach The paper approaches strategic issues in cross-border acquisitions using an illustration of a successful deal. It is based on statements of leaders and secondary data about the acquirer and acquired organizations. The paper explores the strategic challenges faced when emerging market firms carry out cross border acquisition deals. It recommends the short-term and long-term strategies that acquirers can follow to improve the chances of a successful acquisition. Findings Any acquisition is challenging. Cross-border acquisitions face greater challenges, especially if the acquirer is from an emerging market country while the target company is from a developed country. Success of the acquisition, especially over the long run, depends on both internal factors that are under the control of the acquirer’s management, as well as external environmental factors that it needs to address. Both patience and luck are required ingredients for success in such contexts. Practical implications While the general temptation in any acquisition is to extract synergies as quickly as possible, the Tata Motors’ acquisition of JLR is an exception. Tata Motors carefully handled short-term challenges and continued to invest in the core competencies of JLR and reaped benefits over the long run. It was also fortunate that a variety of factors in the external environment turned favorable for Tata Motors and JLR in the eight years since the deal took place. Social implications It concedes that during an M&A deal, the leaders of a seller organization may be nervous about their future. JLR trade union leaders were initially not sure whether jobs in UK would remain secure. To ensure success of the deal, the leaders of the acquirer firm need to balance the interests of multiple stakeholders, both in the short-term, as well as over a longer-term perspective. Originality/value The paper considers the Tata Motors’ acquisition of JLR. It is an example of a large, difficult cross-border acquisition by an emerging market based company. While the acquisition proved difficult in the short term, it has yielded excellent dividends to the parent company over the long term. This paper explores the reasons why this cross-border acquisition succeeded and recommends strategies that other companies considering cross-border acquisitions can consider to improve their chances of success.

Texte intégralRésumé :
Purpose – This study aims to build on the organizational learning theory and propose a complex strategy by combining strategic alliance with subsequent acquisitions to penetrate new product markets. The authors empirically examined whether and to what extent preacquisition alliance experience affects the short- and long-term stock performance of acquiring firms. Design/methodology/approach – Data on acquisitions, in which the acquirers have experience from preacquisition alliance activities in their targets’ respective industry, were collected. Diversifying acquisitions were focused upon to ensure that preacquisition alliance experience is the major source of organizational learning. A standard event study to examine acquirers’ abnormal returns was used and a Fama-French calendar-time portfolio approach to gauge long-run abnormal stock performance was adopted. In addition, regression analysis was conducted to investigate the alliance–acquisition relationship, controlling a set of variables capturing firm and acquisition characteristics. Findings – It has been documented that in the short run, alliance experience may not always benefit acquirers’ stock performance surrounding the acquisition announcements. In particular, for acquiring firms experiencing negative cumulative abnormal returns, investors value alliance experience negatively. However, for up to 36 months after acquisitions, acquirers with alliance experience outperform their counterparts in almost every acquisition category regardless of the short-term announcement returns. Originality/value – The current study has used a large-scale representative sample to investigate the dynamic interaction between alliances and acquisitions as two organizational forms for firms to grow. Findings indicate that firms can deliberately learn from their alliance activities and, later on, enter new markets through acquisitions. More importantly, it was found that, at least for some acquirers, preacquisition alliance activities are associated with worse short-term stock price performance because of possible information spillover and lifted entry barriers. It was confirmed that short-term pain nets long-term gains for acquirers heading into new markets.

Texte intégralRésumé :
The Central Research Institute of Electric Power Industry conducted research to develop a long-term monitoring technology to clarify pore water pressure and water chemistry in drilled boreholes. An automatic data acquisition system for the long-term monitoring was also developed. The automatic data acquisition system has an independent electric power supply and data communication system. The electric power is supplied from solar and wind power. The data communication is secured through a satellite or 3G/4G line. A very low power consumption system can be readily installed by creating personal area networks between measuring devices using Zigbee digital radio. A demonstration of the system was conducted under harsh natural conditions for 18 months. It was confirmed that the system has sufficient reliability for actual operation.

Texte intégralRésumé :
It has been proposed (Krashen, 1981; 1982; 1985; Schwartz and Gubala- Ryzak, 1992; Schwartz, 1986; 1988; 1993) that L2 acquisition proceeds in essentially the same manner as L1 acquisition (the L1 = L2 position). That is, learners acquire underlying unconscious knowledge of a language (called lin guistic competence) simply by being exposed to the linguistic input (called primary linguistic data) in the environment. Instruction and error correction play no role in the development of competence in the L2. This article reports the long-term results of a study investigating the role of primary linguistic data in the acquisition of linguistic competence - in par ticular, the rules of adverb placement in English. This study examines the knowledge of adverb placement of 52 grade-6 francophone students (aver age age: 12 years, 2 months) learning English as a second language (ESL) in Québec schools. A year earlier, these subjects had been exposed over a two- week period to a flood of primary linguistic data on adverb placement in English. Immediately after the input flood, it was found that while the sub jects had learnt which adverb positions were grammatical in English, they still used positions which were ungrammatical in English but grammatical in the L1. The results of the follow-up test reported in this article reveal that one year after the input flood, the subjects' knowledge of adverb placement has not changed. They still use both the grammatical and the ungrammatical adverb positions, indicating that exposure to an abundance of primary lin guistic data on adverb placement did not lead to mastery of this structure. Possible explanations for these results and their implications for the L1 = L2 position are discussed.

Texte intégralRésumé :
ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, NevadaWhile any vehicle that is typically part of a flight test campaign is heavily instrumented to validate its performance, long term vehicle health monitoring is performed by a significantly reduced number of sensors due to a number of issues including cost, weight and maintainability. The development and deployment of smart sensor buses has reached a time in which they can be integrated into a larger data acquisition system environment. The benefits of these types of buses include a significant reduction in the amount of wiring and overall system complexity by placing the appropriate signal conditioners close to their respective sensors and providing data back over a common bus, that also provides a single power source. The use of a smart-sensor data collection bus, such as IntelliBus™1 or IEEE-1451, along with the continued miniaturization of signal conditioning devices, leads to the interesting possibility of permanently embedding data collection capabilities within a vehicle after the initial flight test effort has completed, providing long-term health-monitoring and diagnostic functionality that is not available today. This paper will discuss the system considerations and the benefits of a smart sensor based system and how pieces can be transitioned from flight qualification to long-term vehicle health monitoring in production vehicles.

Striegel, Lucas. « Etudes numérique et expérimentale de récupérateurs d’eaux pluviales enterrés géothermiques pour le rafraîchissement passif des bâtiments ». Electronic Thesis or Diss., Strasbourg, 2024. http://www.theses.fr/2024STRAD060.
Texte intégralRésumé :
Face au changement climatique, caractérisé notamment par des périodes caniculaires plus longues et intenses, mais aussi par une disponibilité irrégulière de la ressource en eau, il est nécessaire d’apporter des solutions sobres en consommations énergétiques pour renforcer la résilience des bâtiments. Les cuves de récupération d’eaux de pluie enterrées sont des systèmes de plus en plus exploités qui permettent la gestion et le stockage de l’eau. En y immergeant un échangeur de chaleur, il est possible de profiter de l’effet géothermique de l’eau et du sol environnant pour rafraîchir les bâtiments de façon passive. Ce travail de recherche vise à étudier les performances et la faisabilité de ces systèmes hybrides. Un modèle numérique a été développé et validé grâce aux données recueillies par l’instrumentation de prototypes à l’échelle 1 pendant près de trois ans. L’exploitation du modèle a mis en évidence les facteurs influents du système. Des règles de prédimensionnement pour évaluer la quantité d’énergie potentiellement récupérable ont ensuite été établies. Le modèle du système a ensuite été intégré dans un outil de simulation énergétique du bâtiment pour évaluer les gains en termes de confort des occupantsIn the face of climate change, characterized by longer and more intense heatwaves, as well as irregular availability of water resources, it is essential to provide energy-efficient solutions to strengthen the resilience of buildings. Underground rainwater tanks are increasingly being exploited as systems for managing and storing water. By immersing a heat exchanger in the tank, it is possible to harness the geothermal effect of the water and surrounding soil to passively cool buildings. This research aims to study the performance and feasibility of these hybrid systems. A numerical model was developed and validated using data collected from the monitoring of full-scale prototypes over a period of nearly three years. The model was used to highlight the key factors influencing the system. The model was used to identify the factors influencing the system. Presizing rules were then established to assess the amount of energy that could potentially be recovered. The system model was then integrated into a building energy simulation tool to assess the gains in terms of occupant comfort

The contemporary need for inter-device data communication is increasing rapidly. Most devices can link to the Internet via a personal computer (PC). However, implementation of device/Internet/device linkage requires at least two PCs. This is a prohibitively expensive arrangement for most situations. A prototype of an Internet-based data acquisition system is proposed here. It consists of a central PC-based server and multiple microcontroller-based devices for measurement. This study discusses the possible network environments for the proposed system and the way of configuration of network setting. A user interface design was also discussed. For applying the system to heterogeneous applications, two examples of applications of drug storage and long-term vital signs of chronic patients were discussed. The first study proposed an Internet-based data acquisition system. The proposed system consists of one PC-based central server and multiple microcontroller-based devices, while most of the other similar Internet-based data acquisition systems consists of all PCs. For acquiring data, the proposed system can effectively reduce the required number of PCs depending on the scale of the whole system. As for the security, because we used the microcontroller-based device to replace PC and it has no operating system and file system, it is impossible for a hacker to access the proposed device by the normal methods of accessing a PC. Therefore, the security issue would be limited to only one PC and be solved by normal ways of firewall and management of people. It can reduce the security loading effectively. The second study enhanced the performance of the microcontroller-based device proposed in the first study. This study proposed a simple method of designing a user interface. The method was developed for multitask issue of the microcontroller-based device used in an Internet-based system. The proposed method is independent from library, and can be implemented easily to the other microcontrollers. For the network configuration of a microcontroller-based device, this study proposed Zero-Configuration. There were several benefits on the proposed microcontroller-based device. One is its booting time of being less than five seconds, while the booting time of PC is over 20 seconds. The other benefits are low cost, small size and low power consumption.

Texte intégralRésumé :
Electricity has penetrated deeply into virtually every aspect of American life, be it in industry, the home, or in the rapidly growing commercial and service sectors. This book documents and analyzes the existence of a strong, and growing, synergy between technological progress and the use of electrified production techniques in the United States during the twentieth century. The authors use two types of information in their work: case studies of the ways in which technological progress in particular industries and economic sectors has depended upon the adoption of electrified methods of production and aggregative long-term national economic statistics that measure the changing relationship over time between increases in the use of electricity and other factor inputs and the growth in industrial productivity. Eleven of the book's thirteen chapters cover the case studies, while the remaining two chapters and the statistical appendix contain the broad quantitative findings and supporting data. In their analysis, the authors address three inter-related questions from a long-term evolutionary perspective: Why has electricity's share of total energy risen so sharply over the years? How has this rise been related to productivity growth? and Why has the rise in electricity led to long-term improvements in the efficiency of overall energy use despite the thermal energy losses sustained when fuels are converted into electricity? The answer to these questions, they contend, is the technological progress represented by electrified production technologies, and in the new ways of organizing production that are now possible. The different ways in which electrical energy has been put to work, and with what results, are examined in the various case studies presented, and further documented in the aggregative statistical analysis. This study reveals the important role that the electrification of production operations has played in supporting productivity growth in manufacturing and other economic sectors in the past, and the important part that it can continue to play in the future. This book will appeal to a broad spectrum of readers; those interested in productivity issues, energy policy, electricity in general, historians of technology, economic historians, and those interested in current technological issues. It will be a necessary acquisition for college and university libraries, as well as those individuals interested in energy, technology, economic growth, history, and the interfaces among them.

Texte intégralRésumé :
AbstractAutomation solutions in production represent a sensible and long-term cost-effective alternative to manual work, especially for physically strenuous or dangerous activities. However, especially for small companies, automation solutions are associated with a considerable initial complexity and a high effort in planning and implementation. The ROBOTOP project, a consortium of industrial companies and research institutes has therefore developed a flexible web platform for the simplified, modular planning and configuration of robot-based automation solutions for frequent tasks. In this paper, an overview of the project’s scientific findings and the resulting platform is given. Therefore, challenges due to the scope of knowledge-based engineering configurators like the acquisition of necessary data, its description, and the graphical representation are outlined. Insights are given into the platform’s functions and its technical separation into different Microservices such as Best Practice selection, configuration, simulation, AML-data-exchange and spec-sheet generator with the focus on the configuration. Finally, the user experience and potentials are highlighted.

Texte intégralRésumé :
For those who may have skipped to this chapter and not read the 3 introductory chapters, the 36 essays, or the 4 evaluative chapters of this book, the answer to the burning question “Does participation in the Long-Term Ecological Research (LTER) program change scientists?” is an unequivocal “Yes!” As Boyer and Brown (Chapter 41) point out, however, those changes are mostly in the realms of knowledge acquisition and behavior adoptions in the practice of science. Participation in the program did not appear to have a substantial effect on the development of attitudes. Could such changes have occurred outside of the LTER program? Schlesinger (Chapter 40) thinks so. He suggests that the LTER program provides “some structure and modest standardization to a set of common measurements” but that it has not substantially broadened or deepened the ecological sciences. Yet the effect of the LTER program on science, while a fascinating and often-addressed question, is not the focus of this book (see Willig and Walker, Chapter 1). Of course, to address how scientists change also involves understanding how they approach and conduct science. In addition, personal change occurs in a broad societal context. For example, the LTER program has coincided with and helped promote a transition in ecology from research done by one or a few investigators on a particular organism or process in a particular habitat to investigations involving multidisciplinary teams working together to test models about how ecosystem dynamics unfold across large spatial and temporal scales. However, going to “big programs” and “big data sets” does not mean losing a sense of place or being divorced from the natural history of particular organisms. Even as spatial and temporal scales increase, ecological research is ideally still “place aware” (Bestelmeyer, Chapter 19). Using the essays of this book as a rich source of information to address fundamental questions about the nature of scientists, we provide some final thoughts on how the LTER program has affected its participants, particularly on how they view time and space, collaboration, and communication. We end with reflections on the future of ecology and society, based on the views expressed in this book and on our own participation in the LTER program.

Texte intégralRésumé :
Transitioning US healthcare into the digital era is necessary to reduce operational costs at Healthcare Organizations (HCO) and provide better diagnostic tools for healthcare professionals by making digital patient data available in a timely fashion. Such a transition requires that the Personal Health Information (PHI) is protected in three different phases of the manipulation of digital patient data: 1) Acquisition, 2) Storage, and 3) Computation. While being able to perform analytics or using such PHI for long-term health monitoring can have significant positive impacts on the quality of healthcare, securing PHI in each one of these phases presents unique challenges in each phase. While established encryption techniques, such as Advanced Encryption Standard (AES), can secure PHI in Phases 1 (acquisition) and 2 (storage), they can only assure secure storage. Assuring the data privacy in Phase 3 (computation) is much more challenging, since there exists no method to perform computations, such as analytics and long-term health monitoring, on encrypted data efficiently. In this chapter, the authors study one emerging encryption technique, called Fully Homomorphic Encryption (FHE), as a candidate to perform secure analytics and monitoring on PHI in Phase 3. While FHE is in its developing stages and a mainstream application of it to general healthcare applications may take years to be established, the authors conduct a feasibility study of its application to long-term patient monitoring via cloud-based ECG data acquisition through existing ECG acquisition devices.

Texte intégralRésumé :
Much of what we know about the structure of the boundary layer is empirical, the result of painstaking analysis of observational data. As our understanding of the boundary layer evolved, so did our ability to define more clearly the requirements for sensing atmospheric variables and for processing that information. Decisions regarding choice of sampling rates, averaging time, detrending, ways to minimize aliasing, and so on, became easier to make. We find we can even standardize most procedures for real-time processing. The smaller, faster computers, now within the reach of most boundary layer scientists, offer virtually unlimited possibilities for processing and displaying results even as an experiment is progressing. The information we seek, for the most part, falls into two groups: (1) time-averaged statistics such as the mean, variance, covariance, skewness, and kurtosis and (2) spectra and cospectra of velocity components and scalars such as temperature and humidity. We discuss them separately because of different sampling and processing requirements for the two. A proper understanding of these requirements is essential for the successful planning of any experiment. In this chapter we discuss these considerations in some detail with examples of methods used in earlier applications. We will assume that sensors collecting the data have adequate frequency response, precision, and long-term stability and that the sampling is performed digitally at equally spaced intervals. We also assume that the observation heights are chosen with due regard to sensor response and terrain roughness. For calculations of means and higher order moments we need time series that are long enough to include all the relevant low-frequency contributions to the process, sampled at rates fast enough to capture all the high-frequency contributions the sensors are able to measure. Improper choices of averaging times and sampling rates can indeed compromise our statistics. We need to understand how those two factors affect our measurements in order to make sensible decisions on how long and how fast to sample.

Texte intégralRésumé :
Self-discovery learning, theoretically, can apply to the extreme ends of human endeavor—the acquisition and maintenance of in-depth expertise over long periods of time. Long-term persistence and focus have always been difficult challenges, even with the enabling structures of educational and career tracks. The inherent unstructuredness and informal aspects of self-discovery learning may make it harder for people to maintain long-term focused interests and investments in their learning. However, the creation of social collaborative work spaces for communities (and networks) of practice and the wide accessibility of various data sets online may be the nascent elements of more elite enabling spaces that may address the “commitment problem” for long-term persistent attention.

Texte intégralRésumé :
Online lottery promotion during holidays has become an important approach for online communities to attract new users and activate current members. The objective of this study is to empirically examine the influence of an online lottery promotional campaign on user acquisition and user engagement from both short-term and long-term perspectives. The aquired data recorded individual users' daily activities on the mobile application before, during and after the lottery promotional campaign, as well as users' participation in the lottery draw and the awards received. This study found that the online promotion attracted more users to register, activated the registered users during the lottery promotion and the users who won non-virtual prize (monetary prize) will be more active in commenting after the promotion. While in the long run all the users' posting activities slightly decreased after the promotion, the lottery promotional campaign is effective in attracting and activating users in short term period.

Texte intégralRésumé :
While long-term monitoring and stewardship means many things to many people, DOE has defined it as: “The physical controls, institutions, information, and other mechanisms needed to ensure protection of people and the environment at sites where DOE has completed or plans to complete cleanup (e.g., landfill closures, remedial actions, and facility stabilization).” Across the United States, there are thousands of contaminated sites with multiple contaminants released from multiple sources where contaminants have transported and commingled. The U.S. government and U.S. industry are responsible for most of the contamination and are landowners of many of these contaminated properties. These sites must be surveyed periodically for various criteria including structural deterioration, water intrusion, integrity of storage containers, atmospheric conditions, and hazardous substance release. The surveys, however, are intrusive, time-consuming, and expensive and expose survey personnel to radioactive contamination. In long-term monitoring, there’s a need for an automated system that will gather and report data from sensors without costly human labor. In most cases, a SCADA (Supervisory Control and Data Acquisition) unit is used to collect and report data from a remote location. A SCADA unit consists of an embedded computer with data acquisition capabilities. The unit can be configured with various sensors placed in different areas of the site to be monitored. A system of this type is static, i.e., the sensors, once placed, cannot be moved to other locations within the site. For those applications where the number of sampling locations would require too many sensors, or where exact location of future problems is unknown, a mobile sensing platform is an ideal solution. In many facilities that undergo regular inspections, the number of video cameras and air monitors required to eliminate the need for human inspections is very large and far too costly. HCET’s remote harsh-environment surveyor (RHES) is a robotic platform with SCADA capabilities equipped with a sonar-imaging scanner, a high-resolution color CCD camera, and various combinations of sensors. The RHES is controlled remotely via a PC. This paper will discuss the development and application of this system.

Monitoring Ecological Restoration with Imagery Tools (MERIT) : Python-based decision support tools integrated into ArcGIS for satellite and UAS image processing, analysis, and classification. Engineer Research and Development Center (U.S.), avril 2021. http://dx.doi.org/10.21079/11681/40262.
Texte intégralRésumé :
Monitoring the impacts of ecosystem restoration strategies requires both short-term and long-term land surface monitoring. The combined use of unmanned aerial systems (UAS) and satellite imagery enable effective landscape and natural resource management. However, processing, analyzing, and creating derivative imagery products can be time consuming, manually intensive, and cost prohibitive. In order to provide fast, accurate, and standardized UAS and satellite imagery processing, we have developed a suite of easy-to-use tools integrated into the graphical user interface (GUI) of ArcMap and ArcGIS Pro as well as open-source solutions using NodeOpenDroneMap. We built the Monitoring Ecological Restoration with Imagery Tools (MERIT) using Python and leveraging third-party libraries and open-source software capabilities typically unavailable within ArcGIS. MERIT will save US Army Corps of Engineers (USACE) districts significant time in data acquisition, processing, and analysis by allowing a user to move from image acquisition and preprocessing to a final output for decision-making with one application. Although we designed MERIT for use in wetlands research, many tools have regional or global relevancy for a variety of environmental monitoring initiatives.

Texte intégralRésumé :
Both the genes and cDNA sequences encoding the b-subunits of black carp LH and FSH were isolated, cloned and sequenced. Sequence analysis of the bcFSHb and LHb5'flanking regions revealed that the promoter region of both genes contains canonical TATA sequences, 30 bp and 17 bp upstream of the transcription start site of FSHb and LHb genes, respectively. In addition, they include several sequences of cis-acting motifs, required for inducible and tissue-specific transcriptional regulation: the gonadotropin-specific element (GSE), GnRH responsive element (GRE), half sites of estrogen and androgen response elements, cAMP response element, and AP1. Several methods have been employed by the Israeli team to purify the recombinant b subunits (EtOH precipitation, gel filtration and lentil lectin). While the final objective to produce pure recombinantGtH subunits has not yet been achieved, we have covered much ground towards this goal. The black carp ovary showed a gradual increase in both mass and oocyte diameter. First postvitellogenic oocytes were found in 5 yr old fish. At this age, the testes already contained spermatozoa. The circulating LH levels increased from 0.5 ng/ml in 4 yr old fish to >5ng/ml in 5 yr old fish. In vivo challenge experiments in black carp showed the initial LH response of the pituitary to GnRH in 4 yr old fish. The response was further augmented in 5 yr old fish. The increase in estradiol level in response to gonadotropic stimulation was first noted in 4 yr old fish but this response was much stronger in the following year. In vivo experiments on the FSHb and LHb mRNA levels in response to GnRH were carried out on common carp as a model for synchronom spawning cyprinids. These experiments showed the prevalence of FSHP in maturing fish while LHP mRNA was prevalent in mature fish, especially in females. The gonadal fat-pad was found to originate from the retroperitoneal mesoderm and not from the genital ridge, thus differing from that reported in certain amphibians This tissue possibly serves as the major source of sex steroids in the immature black carp. However, such a function is taken over by the developing gonads in 4 yr old fish. In the striped bass, we described the ontogeny of the neuro-endocrine parameters along the brain-pituitary-gonadal axis during the first four years of life, throughout gonadal development and the onset of puberty. We also described the responsiveness of the reproductive axis to long-term hormonal manipulations at various stages of gonadal development. Most males reached complete sexual maturity during the first year of life. Puberty was initiated during the third year of life in most females, but this first reproductive cycle did not lead to the acquisition of full sexual maturity. This finding indicates that more than one reproductive cycle may be required before adulthood is reached. Out of the three native GnRHs present in striped bass, only sbGnRH and cGnRH II increased concomitantly with the progress of gonadal development and the onset of puberty. This finding, together with data on GtH synthesis and release, suggests that while sbGnRH and cGnRH II may be involved in the regulation of puberty in striped bass, these neuropeptides are not limiting factors to the onset of puberty. Plasma LH levels remained low in all fish, suggesting that LH plays only a minor role in early gonadal development. This hypothesis was further supported by the finding that experimentally elevated plasma LH levels did not result in the induction of complete ovarian and testicular development. The acquisition of complete puberty in 4 yr old females was associated with a rise in the mRNA levels of all GtH subunit genes, including a 218-fold increase in the mRNA levels of bFSH. mRNA levels of the a and PLH subunits increased only 11- and 8-fold, respectively. Although data on plasma FSH levels are unavailable, the dramatic increase in bFSH mRNA suggests a pivotal role for this hormone in regulating the onset and completion of puberty in striped bass. The hormonal regulation of the onset of puberty and of GtH synthesis and release was studied by chronic administration of testosterone (T) and/or an analog of gonadotropin-releasing hormone (G). Sustained administration of T+G increased the mRNA levels of the PLH subunit to the values characteristic of sexually mature fish, and also increased the plasma levels of LH. However, these changes did not result in the acceleration of sexual maturation. The mRNA levels of the bFSH subunit were slightly stimulated, but remained about 1/10 of the values characteristic of sexually mature fish. It is concluded that the stimulation of FSH gene expression and release does not lead to the acceleration of sexual maturity, and that the failure to sufficiently stimulate the bFSH subunit gene expression may underlie the inability of the treatments to advance sexual maturity. Consequently, FSH is suggested to be the key hormone to the initiation and completion of puberty in striped bass. Future efforts to induce precocious puberty in striped bass should focus on understanding the regulation of FSH synthesis and release and on developing technologies to induce these processes. Definite formulation of hormonal manipulation to advance puberty in the striped bass and the black carp seems to be premature at this stage. However, the project has already yielded a great number of experimental tools of DNA technology, slow-release systems and endocrine information on the process of puberty. These systems and certain protocols have been already utilized successfully to advance maturation in other fish (e.g. grey mullet) and will form a base for further study on fish puberty.

Texte intégralRésumé :
Bridges often serve as key links in local and national transportation networks. Bridge closures can result in severe costs, not only in the form of repair or replacement, but also in the form of economic losses related to medium- and long-term interruption of businesses and disruption to surrounding communities. In addition, continuous functionality of bridges is very important after any seismic event for emergency response and recovery purposes. Considering the importance of these structures, the associated structural design philosophy is shifting from collapse prevention to maintaining functionality in the aftermath of moderate to strong earthquakes, referred to as “resiliency” in earthquake engineering research. Moreover, the associated construction philosophy is being modernized with the utilization of accelerated bridge construction (ABC) techniques, which strive to reduce the impact of construction on traffic, society, economy and on-site safety. This report presents two bridge systems that target the aforementioned issues. A study that combined numerical and experimental research was undertaken to characterize the seismic performance of these bridge systems. The first part of the study focuses on the structural system-level response of highway bridges that incorporate a class of innovative connecting devices called the “V-connector,”, which can be used to connect two components in a structural system, e.g., the column and the bridge deck, or the column and its foundation. This device, designed by ACII, Inc., results in an isolation surface at the connection plane via a connector rod placed in a V-shaped tube that is embedded into the concrete. Energy dissipation is provided by friction between a special washer located around the V-shaped tube and a top plate. Because of the period elongation due to the isolation layer and the limited amount of force transferred by the relatively flexible connector rod, bridge columns are protected from experiencing damage, thus leading to improved seismic behavior. The V-connector system also facilitates the ABC by allowing on-site assembly of prefabricated structural parts including those of the V-connector. A single-column, two-span highway bridge located in Northern California was used for the proof-of-concept of the proposed V-connector protective system. The V-connector was designed to result in an elastic bridge response based on nonlinear dynamic analyses of the bridge model with the V-connector. Accordingly, a one-third scale V-connector was fabricated based on a set of selected design parameters. A quasi-static cyclic test was first conducted to characterize the force-displacement relationship of the V-connector, followed by a hybrid simulation (HS) test in the longitudinal direction of the bridge to verify the intended linear elastic response of the bridge system. In the HS test, all bridge components were analytically modeled except for the V-connector, which was simulated as the experimental substructure in a specially designed and constructed test setup. Linear elastic bridge response was confirmed according to the HS results. The response of the bridge with the V-connector was compared against that of the as-built bridge without the V-connector, which experienced significant column damage. These results justified the effectiveness of this innovative device. The second part of the study presents the HS test conducted on a one-third scale two-column bridge bent with self-centering columns (broadly defined as “resilient columns” in this study) to reduce (or ultimately eliminate) any residual drifts. The comparison of the HS test with a previously conducted shaking table test on an identical bridge bent is one of the highlights of this study. The concept of resiliency was incorporated in the design of the bridge bent columns characterized by a well-balanced combination of self-centering, rocking, and energy-dissipating mechanisms. This combination is expected to lead to minimum damage and low levels of residual drifts. The ABC is achieved by utilizing precast columns and end members (cap beam and foundation) through an innovative socket connection. In order to conduct the HS test, a new hybrid simulation system (HSS) was developed, utilizing commonly available software and hardware components in most structural laboratories including: a computational platform using Matlab/Simulink [MathWorks 2015], an interface hardware/software platform dSPACE [2017], and MTS controllers and data acquisition (DAQ) system for the utilized actuators and sensors. Proper operation of the HSS was verified using a trial run without the test specimen before the actual HS test. In the conducted HS test, the two-column bridge bent was simulated as the experimental substructure while modeling the horizontal and vertical inertia masses and corresponding mass proportional damping in the computer. The same ground motions from the shaking table test, consisting of one horizontal component and the vertical component, were applied as input excitations to the equations of motion in the HS. Good matching was obtained between the shaking table and the HS test results, demonstrating the appropriateness of the defined governing equations of motion and the employed damping model, in addition to the reliability of the developed HSS with minimum simulation errors. The small residual drifts and the minimum level of structural damage at large peak drift levels demonstrated the superior seismic response of the innovative design of the bridge bent with self-centering columns. The reliability of the developed HS approach motivated performing a follow-up HS study focusing on the transverse direction of the bridge, where the entire two-span bridge deck and its abutments represented the computational substructure, while the two-column bridge bent was the physical substructure. This investigation was effective in shedding light on the system-level performance of the entire bridge system that incorporated innovative bridge bent design beyond what can be achieved via shaking table tests, which are usually limited by large-scale bridge system testing capacities.

Generation II Coastal Risk Model (G2CRM). Engineer Research and Development Center (U.S.), décembre 2022. http://dx.doi.org/10.21079/11681/46260.
Texte intégralRésumé :
The U.S. Army Corps of Engineers (USACE or Corps) has a mission to manage flood risks: “The USACE Flood Risk Management Program (FRMP) works across the agency to focus the policies, programs and expertise of USACE toward reducing overall flood risk. This includes the appropriate use and resiliency of structures such as levees and floodwalls, as well as promoting alternatives when other approaches (e.g., land acquisition, flood proofing, etc.) reduce the risk of loss of life, reduce long-term economic damages to the public and private sector, and improve the natural environment.” As a part of that mission, the Institute for Water Resources (IWR) in cooperation with other Corps groups has developed the Generation II Coastal Risk Model (G2CRM) to support planning-level studies of hurricane protection systems (HPS). The G2CRM is distinguished from other models currently used for that purpose by virtue of its focus on probabilistic life cycle approaches. This allows for examination of important long-term issues including the impact of climate change and avoidance of repetitive damages. Key features of the model include the ability to use readily available data from existing sources and corporate databases and integration with geographic information systems (GIS). The G2CRM generates a wide variety of outputs useful for estimating damages and costs, characterizing and communicating risk, and reporting detailed model behavior, in the without-project condition and under various plan alternatives for the with-project condition.
