The Primary objective of Automatic Railway Bridge System is to help the physically Challenged Passenger to move from one Platform to another. Crossing the railway track inside the railway station is very difficult. But it is quite difficult to the handicapped and aged persons to cross the railway track without the help of other. The proposed system uses the train time for opening and closing of bridges. This is done by wireless communication. Each train is connected with RF transceiver, which will send a data of arrival before it reaches the station platform. If the train leaves the platform, the automatically the mobile platform will be bridged between two platforms to build a path between them. This project is designed with arduino microcontroller. The arduino microcontroller gives the input from the RSSI and give command to the motor to run in order to change in the position of open and close the mobility rostrum

Abstract In order to improve the risk early-warning performance of highway bridges caused by typhoon disasters, a fast and intelligent risk assessment model for highway bridges is proposed in this paper. A three-level accident possibility index system is established in which the top-level index is the possibility of bridge accident, the second-level indices comprise the accident causing factor, the surrounding environment factor, and the accident bearing body, and the third-level indices are selected from the disaster conditions and the bridge’s own technical conditions. With the rapid risk assessment model of highway bridges under typhoon disasters, the intelligent risk assessment software platform is developed. In the case analysis, the automatic and intelligent risk assessment of highway bridges in Ningbo under Typhoon “Lekima” on August 10, 2019, was realized.

preventive inspection of railway bridges is a key step for an effective maintenance program. The TOSCA-FI project has developed an integrated ICT platform for easy access to a wide set of data, obtained with several imaging techniques (high definition photography, photogrammetry, 3D scanning, fluorescence LIDAR and thermography) and integrated into a 3D model of the bridge. The aim is to provide a tool to support the inspection of railway bridges, often based exclusively on the visual inspection. In this paper, we present selected results obtained on masonry bridges by using thermography and their integration in the TOSCA-FI platform.

The primary aim of the Automatic Railway Bridge System is to assist physically challenged passengers in moving from one platform to another. Crossing the railway track within the station premises poses significant challenges, especially for the handicapped and elderly individuals, who often require assistance from others. In this study, the agents utilize various resources such as train characteristics, driving regulations, and information pertaining to other trains to formulate their action plan. Many elderly individuals suffer from ailments such as leg cramps, walking difficulties, vein issues, and chronic foot pains, making it imperative to address this issue. To tackle this problem, we propose a project involving the implementation of a horizontally adjusted platform connecting both station platforms. This innovation eliminates the need for both adults and children to climb bridges, thereby saving time for passengers and ensuring smoother operations for all.

Full textAbstract:
Multi Span Continuous Concrete I-Girder Bridges are categorized among the most vulnerable bridge classes. Seismic response assessment for these highway bridges are essential for highway transportation networks exposed to seismic hazards. This study focuses on developing and comparing seismic response of different bridge components for seismically and non-seismically designed bridges that are common in this region. The primary differences between seismically and non-seismically designed bridges are the column details. Detailed three-dimensional (3-D) nonlinear analytical models, which account for the nonlinear behavior of the column, girders, and abutments are developed with the use of OpenSees platform. The seismic behavior of the bridge components are obtained and compared for the case of non-seismically and seismically designed bridges. The results explicitly show that the seismic behavior of the bridge components are significantly affected by seismic detailing of the reinforced concrete column. However, different components are not equally affected by this parameter.

Full textAbstract:
Maritime management is a crucial concern for movable bridge safety. Irregular management of water vehicles near movable bridges may lead to collision among ships and bridge infrastructures, causing massive losses of life and property. The paper presents a theoretical framework and simulation of an intelligent water vehicle management system for movable bridges corresponding to vehicle traffic responses. The water regime around the bridge is considered in virtually separated domains to estimate the desired safety actions based on the position of the approaching ships. An emergency clash avoidance control system is represented to prevent ship-infrastructure collision and ensure transportation safety. In addition, a simulation platform is developed specifically adaptable for movable bridge maritime and dynamic traffic management. The proposed theory is experimented using the simulation platform for different ship speeds and bridge-vehicle traffic volumes. Based on analyzing the velocity profile of approaching ships at different incidents, the bridge is found incapable of evacuating vehicles and unable to open promptly in case of speeding ships and high traffic density of vehicles on the bridge. Computational results show that the emergency control system is effective in reducing ship speed and prevent certain collisions. Lastly, the transportation policy for the newly proposed maritime management system is validated by real-world implementation in movable bridges across the world.

Full textAbstract:
For medium- and small-span bridges, the weight of the superstructure in steel–concrete composite girder bridges is lighter than that of a reinforced concrete girder bridge. However, it is still uncertain whether steel–concrete composite girder bridges exhibit superior seismic performance compared to reinforced concrete girder bridges. This study quantitatively compared the seismic performance of the two types of bridges. Using the theory of probabilistic seismic demand analysis, the seismic vulnerability curves of bridges were derived. To conduct seismic demand analysis for probabilistic analysis on the OpenSEES platform, bridge samples were generated using the Latin hypercube stratified sampling method, which considers the uncertainties associated with the two types of bridges. The vulnerability curves of the piers, bearings, abutments, and the system of the two bridges were established using probabilistic analysis of the time history analyses. The results showed that the seismic vulnerabilities of components and the overall system of the steel–concrete composite girder bridge were both lower than those of the reinforced concrete girder bridge. When the peak ground acceleration (PGA) of the ground motion was 0.3 g, the moderate and serious damage probabilities of the piers in the steel–concrete composite bridge were only 54.61% and 60.89%, respectively, of those of the reinforced concrete bridge. Consequently, replacing the upper reinforced concrete girders with steel–concrete composite girders can significantly improve the seismic performance of a large number of existing bridges.

Bridges play a very important role in the country's economy, as they allow easy transport of goods and passengers through difficult-to-travel areas. They also give a general picture of technological advancement in the land construction sector in the country. With the advancement of civil engineering technology, several materials and technologies have found their way into bridge construction, where bricks, concrete, and steel have been used and different structural configurations are used as needed. These configurations include slab, beam, arch, truss, suspension and cable-stayed bridges. It is important to pay attention to significant bridges in a country and consistently collect available statistical and historical data. This can be useful for future authors and researchers to easily navigate this data and use it for further research, as it is easily accessible consistently on one platform. This paper aims to provide such a platform by listing the most important bridges to Pakistan's growing economy. Several bridges in Pakistan are presented, their history, technical specifications and historical significance. The bridges are shown in chronological order to provide a clear and understandable narrative. Pakistan has been observed to have some remarkable bridges statistically and historically due to the development of the civil engineering sector during pre-independence and post-independence in 1947

Full textAbstract:
Despite immense efforts to realize diverse visions of the ‘smart city,’ municipalities still face manifold uncertainties of how governance and the tools of governance can best support public and regional value creation for achieving urban sustainability. To this end, Urban Living Labs have become a known enabling mechanism. In this paper, we extend the lab idea and formulate the concept of Urban Experimentation Platform that focuses on developing urban innovation ecosystems for urban sustainability. We use action design research and participant observation across multiple case studies enacting Urban Experimentation Platforms in order to investigate how the tie-in between governance and the local lab’s innovation process unfolds. Our analysis distills three facets that are instrumental in institutionalizing these platforms as resilient organizational models. With the help of the case studies, we illustrate the three facets, concerning issues of urban ecosystem governance, empowering co-creation, and qualifying local innovation. The facets reinforce the roles of digital instruments and digital capabilities for effective urban governance and platform management. We draw some conclusions for future research and formulate policy recommendations for implementing and operating Urban Experimentation Platforms.

In recent years, when building bridges across existing railways, in order to reduce the interference to the railway operation line during the construction process, parallel railways are often used to cast bridges and then rotate them. In this paper, combined with the engineering example of Zhaochuan Super Swivel Bridge on Beijing-Zhanghai High-speed Railway, the key and difficult points of the swivel bridge during construction are monitored, and compared with the computer simulation data, the static friction coefficient, dynamic friction coefficient and friction couple distance of the swivel system are obtained. Model each component of the bridge body, establish a safety monitoring and early warning method, system, storage medium, and early warning platform, and visually display the safety degree of components at different stages and locations by color discrimination.

Full textAbstract:
The main focus of this thesis is the theoretical investigations of a nanogap platform used for molecular electronics measurements under ambient conditions. The nanogap is about 20 nm wide, while the molecules investigated here (octanethiol(OT) and octanedithiol(ODT)) are about 1-1.5 nm long making it impossible to bridge the gap with one molecule. Two different approaches are investigated. In the first approach the electrodes of the nanogap are coated with a layer of OT molecules, and large gold nanoparticles (diameter of about 30 nm) are trapped in the gap creating two molecular junctions with assemblies of molecules. In the second approach the electrodes are kept clean, but instead the gold nanoparticles are coated with doubly functionalized molecules (ODT) and trapped in the gap. Here the nanoparticles are limited in size to about 5 nm, hence it is necessary to consider nanoparticle-molecule chains or small networks to bridge the gap. The first principles modeling of the structure of the metal-molecule junctions combined with elastic and inelastic transport properties is performed using the density functional theory (DFT) combined with the non-equilibrium Green’s functions (DFT-NEGF) method. In the first approach with the coated electrodes and the large nanoparticles, simulations show that structural irregularities at the electrode interface can lead to a significant variation of the conductance through the molecular film. Due to the size of the nanoparticles, the shape and orientation of the facets will have great influence on how many molecules are connected, affecting the measured resistance of the device. With the second approach utilizing the functionalized nanoparticles, more stable junctions are obtained since the nanogap is bridged by molecular junctions chemisorbed in both ends. To make chemical bonds to both sides of the junctions, the outer functional group needs to be protected before the trapping of nanoparticles in the gap. Deprotected nanoparticles agglomerate and cannot be trapped. We have inves- tigated the most probable configurations of the molecules in these junctions. During deprotection of the functional group in the gap, a conduction increase have been observed. We have found that the removal of the protection group is not responsible for the increased conduction. Instead, since the deprotected molecule is shorter and the nanoparticles are mobile during deprotection, a reorganization of the nanopar- ticles in the gap occurs. This reorganization leads to decreasing of the tunneling length for the electrons, hence increasing the conduction. We also demonstrate, that we can obtain the inelastic electron tunneling spectroscopy (IETS) signature of an octanedithiol molecule in this platform. This is done on the network of chemisorbed ODT junctions, where we are able to relate the low-bias Au-S and C-S stretch modes of the molecule to observed peaks in IETS. From this we estimate that the main contribution in the signal comes from chains containing 5, 6 and 7 molecular junctions. To identify the peaks, we have calculated the theoretical spectra for one molecule, from which we are able to extract the important vibrational modes, and their couplings to the electrons. This we then use in a model, including the Coulomb blockade observed in the nanoparticles, to fit the theoretical spectra to the measured one.

Segway has been a popular production as an alternative transporter since its invention at the end of 20th century. Millions of people like for its ergonomic design and high-tech elements. It is predicted to be an innovational product to change a person's life style. This thesis focuses on building a simple low cost, home-made Segway style scooter. This project uses two electric scooter motors, two 12V car batteries, one accelerometer and several microprocessors to build up the whole system. Significantly, this project also explains how to build a Brushed Direct Current (BDC) motor driver with a rated output power of more than 350W and the capability of coping with up to 120A transient peak current and up to 40A continuous current. Four-quadrant operation and eight modes of DC motor operation are discussed. A mathematical model of the Segway style scooter is also introduced in details. This including the modelling of a BDC motor, a two-wheeled inverted pendulum and their combination. The linearization of these models is used. At the end the linearized model is simulated in computer software.

Full textAbstract:
Mitochondria and the endoplasmic reticulum (ER) are two organelles that critically contribute to apoptosis induction. It is established that they communicate and several factors for this have been identified. However, how cell death signals are transmitted from mitochondria to ER is unknown. During my PhD, I found that the mitochondrial fission protein Fis1 conveys an apoptosis signal from mitochondria to the ER by physically interacting with Bap31, which facilitates its cleavage into the pro-apoptotic p20Bap31 fragment. Exogenous apoptosis inducers likewise use this signalling route and induce the procession of Bap31. Initiator caspases are the apical apoptosis proteases that comprise protein-protein interaction domains in their N-terminal prodomains, which allow them to aggregate through adaptor proteins. Procaspase-8 is one of the most prominent initiator caspase; yet there are only two known procaspase-8-activating complexes identified to date: DISC and Hip1/Hippi complex. The cleavage of Bap31 is reported to be mediated by procaspase-8. I have found that procaspase-8 is recruited to the Fis1-Bap31 platform early during apoptosis. Apoptosis stimulation induces the dimerization of Bap31 and an in-depth dissection of this tripartite protein complex revealed that the association between procaspase-8 and the Fis1-Bap31 complex is dependent on the vDED domain present in Bap31. This signalling pathway emanating from Fis1 or caused by the application of exogenous apoptosis signals eventually results in calcium release from the ER leading to cytosolic calcium elevation. Additionally, production of the proapoptotic p20Bap31 fragment was found to be necessary for this event. The released calcium ions are subsequently taken up by mitochondria to induce mitochondrial dysfunction via the permeability transition pore thereby establishing a feedback loop from the ER that activates mitochondria for apoptosis execution. Hence, the Fis1-Bap31 complex, which we named ARCosome, bridges two critical organelles for apoptosis signalling and serves as a novel platform to activate the initiator procaspase-8.

Full textAbstract:
This thesis reports on a mixed methods research project into the emerging area of computer simulation in Initial Teacher Education (ITE). Some areas where simulation has become a staple of initial or ongoing education and training, i.e. in health care and military applications, are examined to provide a context. The research explores the attitudes of a group of ITE students towards the use of a recently developed simulation tool and in particular considers the question of whether they view computer simulation as a ‘third place’ between faculty based ‘theory’ elements and school based ‘practice’ elements of their training or whether they consider the simulation to be enhanced ‘theory’ learning. Data from pre-experience and post-experience questionnaires are compared. A series of indicative case studies, representing positive and negative changes in attitude, are presented from data collected using semi-structured interviews. A range of themes emerge indicating that the students’ attitudes towards computer simulation are complex and not based on single factors such as the fidelity of the simulation presented. A major finding of the research is that students’ attitudes towards the computer simulation appear to reflect deep seated views of teaching and learning unrelated to simulation. Indications are that if future use of simulation is to be effective then designers must pay at least as much attention to emotional impact as cognitive development. Evaluation of the success of the study is included and suggestions for further study are made.

Full textAbstract:
In this thesis, a combination of density functional theory (DFT) based calculations and nonequilibrium Green’s functions are employed to investigate electron transport in molecular switches, molecular cords and nanoscale devices. Molecular electronic devices have been proposed as an approach to complement today’s silicon based electronic devices. However, engineering of such miniature devices and design of functional molecular components still present significant challenges. First, the way to connect a molecule to conductive electrodes has to be controlled. We study, in a nanoelectrode-nanoparticle platform, how structural changes affect the measured conductance and how current fluctuations due to these structural changes can be decreased. We find that, for reproducible measurements, it is important to have the molecules chemically bonded to the surfaces of adjacent nanoparticles. Furthermore, we show by a combination of DFT and theoretical modeling that we can identify signals from single-molecules in inelastic electron spectroscopy measurements on these devices. Second, active elements based on molecules, some examples being switches, rectifiers or memory devices, have to be designed. We study molecular conductance switches that can be operated by light and/or temperature. By tuning the substituents on the molecules, we can optimize the shift of the most conducting molecular orbital and increase the effective coupling between the molecule and the electrodes when going from the OFF to the ON-state of the switches, giving high switching ratio (up to three orders of magnitude). We also study so called mechanoswitches that are activated by a mechanical force elongating the molecules, which means that these switches could operate as sensors. Furthermore, we have studied two different classes of compounds that may function either as rigid molecular spacers with a well-defined conductance or as molecular cords. In both cases, we find that it is of great importance to match the conjugation of the anchoring groups with the molecular backbone for high conductance. The last part of the thesis is devoted to another interesting semiconductor material, diamond. We have accurately calculated the band structure and effective masses for this material. Furthermore, these results have been used to calculate the Hall coefficient, the resistivity and the Seebeck coefficient.

For almost one hundred years, Brno has been deciding where the place of a new main train station should be. The works have almost started several times, but the various affairs have always postponed it. Two years ago, it was finally decided that „the River option“ would be constructed. So far, only the technological template has been written – e. g. railway bridge or platforms outline. The thesis focuses on the architectural design of the main building, the roof construction above the railways and spaces below the station bridge. In the design, the outlying urban structures are also dealt with. These include the locations of a bus station, taxi services and bike stands. Moreover, the design also mentions the station’s connection to the city networks. The main motive of the design is to put the main train station building into the centre of the city’s attractions – to make it visible. A boulevard’s view is oriented to the St. Peter’s cathedral – a famous Brno’s building. Just as the mentioned cathedral, the station is important for the city and deserves to be seen. A strong arched construction on four pillars serves as a roof over the railways and places where most visitors are expected to be most of the time. The arch also connects the public transport lines and the bus station. Part of a roof shaped like waves around the main hall connects the structure with the riverside nearby.

Although entwined with other motivations, the primary objective of the Look East Policy was and remains economic. Indian policy makers felt the need to bridge the gap caused by China’s twelve years year head start in liberalizing its economy or risk being marginalized in Asia. The two countries choose, however, radically different strategies:, China becoming became in the process a massive exporter of manufactured goods while India while India specializedspecialized in high-skill service exports, alongside manufactures but failing failed to expand the latter as much as expected. Foreign direct investment played a key role in the strategies of both countries, leading to substantial differences in export output. Because it was meant to develop an export strategy, FDI gave China a decisive advantage in the region. In India, FDI essentially targeted the domestic market and its contribution to manufactured product exports remained limited. China rapidly emerged as the pivot of the Asian export platform, a position that also enhanced its political influence across Asia.

Yet, it argues thereafter that this possible failure of the classical theory of sources should not be construed as a failure of the principle of such a theory, but rather the failure of the specific (representation of the) theory of sources as it was inherited from the twentieth century and depicted by its critiques. More specifically, this chapter puts forward a social theory of sources that makes it possible to construe the theory of sources as a tradition and a practice rather than as a set of rules that operates mechanically.

Full textAbstract:
Abstract This book traces the wedding song tradition, its imagery, and its tropes as a genre that gets crystallized throughout the ages. It explores how wedding poetics permeates ancient Greek literature. It first analyzes how explicit or implicit matrimonial references shape archaic epic diction and become an integral part of epic discourse; orally circulating texts, such as wedding songs, could have a life of their own but, beyond their original context, could also become an integral part of a different genre, especially epic and drama. This work discusses the multiple platforms that enrich the wedding song tradition, including children’s songs, hymns, paeans, and ululations, arguing for a combination of ritualized discourse with ludic childhood poetics. With an approach from cognitive and trauma studies, such references can be more revealing of the female experience than previously acknowledged. This book resists the idea that a wedding constitutes an initiation ritual, arguing that what on the surface may seem like a transition to a new phase reveals other underlying trends that work against the concept of a passage. It further considers how emotion is staged and revisits the poetics of return by looking at patterns such as the eloping, returning, failed, and dead bride. Finally, the theme of separation and return as an exemplification of a distinct female nostos is revisited in female-authored poetry, which helps us decode the complex interweaving of wedding performances and lamentation, among other types of performance.

AbstractOne of the objectives of the European Language Grid is to help overcome the fragmentation of the European Language Technology community by bringing together language resources and technologies, information about them, Language Technology consumers, providers and the wider public. This chapter describes the mechanisms ELG has put in place to build interoperable bridges to related initiatives, infrastructures, platforms and repositories in the wider Language Technology landscape. We focus on the different approaches implemented for the exchange of metadata records about, in a generic sense, resources and exemplify them with the help of four use cases through which the ELG catalogue has been further populated. The chapter presents the protocols used for the population processes as well as the adaptations of the ELG metadata schema and platform policies that proved necessary to be able to ingest these new records.

Full textAbstract:
AbstractSeismic fragility analysis is of paramount significance in studying the seismic characteristics of bridges, especially for special structures like special-shaped bridges. Special-shaped bridges exhibit more complex geometric and mechanical properties. Therefore, it is even more essential to conduct seismic fragility analysis for special-shaped bridges. Analyzing the response of special structures to lateral seismic loads benefits the evaluation of their seismic performance and facilitates enhancements in seismic design. A finite element model was established using Midas/Civil to investigate the seismic fragility of a space special-shaped steel box arch bridge under lateral seismic loads. To assess the seismic fragility of space special-shaped steel box arch bridges, displacement data from bridge abutments, arch support platforms, and bearings were selected as damage indicators. The seismic fragility curves for bridge components were constructed using the incremental dynamic analysis (IDA) method. In the end, the weighting method was adopted to calculate the seismic fragility curve for the entire bridge system. The bearings and bridge abutments are more susceptible to seismic damage under lateral seismic loads, making them the vulnerable components of the bridge. Among the four bearings, the ones located near the arch ribs have poorer seismic performance and constitute vulnerable areas in the bearing layout. Through the case study of the seismic fragility analysis of space special-shaped steel box arch bridge, common issues in the fragility analysis of special bridges were explored. This further provides rational recommendations for enhancing and improving the seismic design of special-shaped bridge structures.

Full textAbstract:
AbstractThis chapter challenges a taken-for-granted split in the platform critical studies: the analysis of platform labour in terms of informalization in the Global North and in terms of formalization in the Global South. Far from totally denying regional specificities in the territorialization of platform capitalism, the author tries to build a bridge between contexts defining a common logic operating through conjunctural geographies: the specific labour process implemented by platforms requires an active engagement by living labour in terms of self-entrepreneurship. This engagement can be produced through the disruption of standard labour as well as through the commodification of informal labour. In both cases, workers have to deal with an acquired dependence from the platform infrastructure. This logic, nevertheless, does not preclude the possibility to overturn self-entrepreneurialism into resistances and exit strategies.

<p>In this paper we present the workings of a new platform designated for assessment and management of a large number of bridges. The platform combines advanced inspection and testing techniques, digital twinning, and Structural Health Monitoring (SHM). The overall goal of the framework developed by Kinemetrics is to construct an SHM platform that will efficiently monitor the safety and reliability of bridge infrastructure in big cities. However, on a more general level, our aim is to increase public safety as well as to reduce life cycle costs of bridge maintenance. For this reason, this project draws special attention to asset management that is supported by appropriate SHM and digital twin technologies. Moreover, this framework takes into account the ways the proposed platform can be successfully implemented for two types of possible events: regular SHM as well as the required examination subsequent to sudden disasters, such as earthquakes.</p>

Full textAbstract:
<p>The rapid advancement of AI technology is transforming traditional bridge design. The general design of bridges primarily relies on the inspiration and experience of designers. To assist designers in achieving rapid and innovative designs, an intelligent bridge design method based on diffusion models (DM) has been proposed. Utilizing the Stable Diffusion AI platform, an image dataset of ideal styles was collected, and LoRA models were trained to generate two-dimensional and three- dimensional styles. These styles were then compared and optimized to achieve style transfer. ControlNet models were trained to generate structures from abstract lines, tangible objects, and classical bridge structures, and these structures were optimized to attain structural transfer. The proposed method was validated through the design examples of pedestrian bridges in Lhasa and Sichuan, China. The results demonstrate that the DM-based intelligent generation design method essentially meets design requirements, effectively reduces design time costs, and improves design efficiency. The intelligent design process achieves the goal of design assistance.</p>

Full textAbstract:
Abstract In recent years, increased service life and structural monitoring requirements are often specified for major bridges which will be built in a marine environment. Previously, different measures were considered to improve the durability of these new structures. These measures included the modification of concrete mix design; an increase in the cover to reinforcement; application of protective coatings; use of corrosion resistant reinforcement; and the use of corrosion inhibitors. With the advancement of structural health monitoring, communication and corrosion technologies in recent years, advanced technologies such as the application of cathodic prevention during construction, structural health monitoring and corrosion monitoring systems are being specified. The combined use of these technologies in one application is the first step in making the new generation of marine structures “intelligent” and providing long term, cost effective monitoring and corrosion control for new structures. This paper will review the most common corrosion prevention measures for reinforced concrete structures in the marine environment and will outline a concept for future “intelligent” structures that can incorporate under one platform and as needed, based on specific conditions, structural health monitoring, corrosion prevention and corrosion monitoring systems. In addition, this paper will also present case studies for two bridges in Finland and Australia where some of these technologies have been incorporated during the construction phase.

The third of three 80-foot by 16-foot platforms is just lifting off the barge. As the platform clears the deck and begins its 150-foot climb to the underside of the bridge, the tug and barge pull away and head back to the dock. I’m one of three workers standing on the deck of the platform as it slowly is winched up, 10 feet, 15 feet, then 20 feet off the water. Suddenly, with a snap and a shout from above, one corner of the platform begins to tip, and the support cable snakes down, splashing and then disappearing into the cold water of the bay. One of the four suspension points on the bridge above has failed. As I instinctively walk towards the falling end to see what’s happening, I am gently lifted by my harness and vertical safety line until I am walking on air, with the partially submerged platform listing about 15 feet below me. It all seems to happen in slow motion. When the worst occurs, there is no time to react or escape; either you planned for the unexpected, or.

Full textAbstract:
Abstract To support strategies for energy production, the expansion of existing offshore facilities and the development of new facilities will be necessary. Bridges play a vital role in enabling these expansions. During complex upgrade processes, additional facilities like personal accommodation platforms, drilling platforms, separation platforms, compression platforms, water handling platforms, and gas platforms will be installed and connected through offshore bridges. These connections will facilitate the sharing of utilities and work systems, both among the existing facilities and the new ones. It is important to emphasize that these developments are complex in nature, involving significant interactions between the brownfield and greenfield sectors. Contractor recently completed an installation project in Indian waters, which involved connecting existing and newly constructed platforms with bridges. The conventional method of installing bridges from the top was not feasible in this case. This was due to the existing topside helideck extending beyond the stabbing location, making direct installation of the bridge impossible. The presence of protrusions from facilities such as piping and electrical utilities also limited sideway installation. To overcome these challenges, adjustments were made to the height of the bridge stabbing pin to increase clearance between the cellar deck (final location) and the helideck. Installation aids in the form of carefully positioned guides and bumpers at the cellar deck level were used to prevent the bridge from moving towards the existing platform, ensuring the protection of piping and facilities from potential impacts. Additionally, specific rigging techniques were employed to induce a tilt on the stabbing pin side of the bridge. A fork-type guide was provided on the bridge to engage with the bumper on the existing platform, allowing for rotation and lowering by aligning the bridge with the bumper on the new platform. Rigorous clash checks using 3D models of the bridges and platforms were conducted at all stages of the installation process. The installation weather window was determined through analysis if required, considering the available clearances. This paper aims to highlight the significant challenges associated with the installation of offshore bridges on typical brownfield projects and explores potential mitigations to overcome these challenges.

Full textAbstract:
Abstract Normally, interconnecting bridges between new and existing platforms are installed separately due to the complexities involved during the engineering and installation phases. The purpose of these bridges is to provide various discipline interfaces, such as electrical, instrumentation, and piping interfaces from the existing platform to the new platform, in addition to personnel access for performing various tasks associated with operational and maintenance aspects. At several locations, the existing and new platforms are located close to each other, resulting in short bridge lengths. The installation of offshore bridges between the platforms is critical due to space constraints, the loading capability of the existing platform, environmental constraints, post-survey data constraints, and dimensional tolerance constraints. Detailed studies were conducted to verify the feasibility of installing the bridge structure along with the new topside. Considering the structural integrity of the existing platform, the bridge structure between the new and existing platforms is supported as a cantilever from the new platform, and therefore no load is transferred to the existing parent tower. The presence of helideck structures, piping, cables, and associated items on the existing platform generates additional challenges while positioning the bridge integrated deck structure towards its final intended location. By integrating the topside and bridge, several benefits can be achieved: Piping, electrical cable, and other utility connections at one end during installation phase offshore can be eliminated.Separate lifting and installation of the bridge structure can be avoided, thereby saving offshore costs and time.Separate transportation and installation of the bridge structure are not required.Saving offshore costs and time for an installation vessel has a direct relation to environmental mitigation. This technical paper covers the strategies applied for the safe installation of integrated bridge and topsides for five offshore platforms in the Arabian Gulf by National Petroleum Construction Company (NPCC). It provides information on the challenges involved in topside installation adjacent to the existing platform and how it contributes to environmental mitigation.

Digital learning platforms (DLPs) can transform educational research by serving as infrastructure that bridges the gap between practice and research. This white paper examines the progress of DLPs in SEERNet, a multi-year initiative funded by the Institute of Education Sciences (IES), which aims to advance research infrastructure. Through coordinated efforts among platform developers, researchers, and practitioners, SEERNet members have addressed both expected and emerging challenges. The paper seeks to support others who are seeking to share platform data with researchers by clarifying the range of requirements. Some requirements were expected; others were emergent. Expected requirements, such as enhancing platform data capabilities, enabling experimental research designs, and protecting data privacy, have focused on technical improvements to support scalable and rigorous research. Emerging needs included the creation of standardized workflows, development of researcher outreach strategies, and establishment of templates for institutional review board (IRB) approvals and data-sharing agreements. In addition, fostering a peer review community attuned to the unique affordances and constraints of DLP-based research has emerged as a shared priority. This working paper reflects on lessons learned from SEERNet’s efforts, highlighting innovations in data documentation, experimental workflows, and collaborative relationship building.

Full textAbstract:
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.

Full textAbstract:
The line between animal and human is often one that is heavily reliant on an individual’s identifications and sense of relationality. The depth of a human-animal bond shifts depending on the established terms of the particular human-animal relationship and the extent of its prior nurturing and the circumstances of its genesis. Animal narratives in turn provide insight into animal individuality that may allow for contemplation of unique, specific approaches applicable to a wide range of circumstances in veterinarian medicine. Some films encompass various facets of the human-animal divide, or lack-thereof, that may aid veterinarians in understanding patient stories. Megan Leavy (2017) examines the shared mindsets of human and canine soldiers shaped through shared circumstances of war. The Mustang (2019) considers similar themes within the confines of imprisonment. Spirit: Stallion of the Cimarron (2002) explores the manifestation of similar desires and character traits between human and animal and the paths undertaken to achieve camaraderie. These narratives create varying viewpoints regarding the importance and validity of relationships with animals all founded on a basic platform of consideration and admiration. Acknowledgement and familiarity with patients’ possible lived experiences become of crucial importance for the veterinarian due to the obvious blockade in communication. Essentially, examination of the animal narrative gives a possible voice to the animal, which bridges the gap between veterinarian and patient and serves as a conduit for more whole medicinal practice.

As the Fourth Industrial Revolution transforms the conduct of work and enterprises, inequalities and the digital-spatial divide become front and center of conversations that aim to promote online marketplaces and maximize their benefits. This paper takes stock of the development in human capital, labor market, and e-commerce, identifies state-led initiatives to build capacities, and analyzes barriers and gaps in labor and retail platforms. Data collected through desk reviews and key informant interviews with stakeholders were synthesized to highlight state-led initiatives and programs related to platform work, identify barriers to participation in the digital economy, and draw recommendations to address gaps. The paper finds that several state-led programs and initiatives for online marketplaces and legislative agenda related to the digital economy are in place. Despite this, the paper finds that (1) barriers related to gender roles, business environments, and financing exist and (2) gaps in social protection, digital competencies, and infrastructure support remain. Some directions to bridge gaps, break barriers to participation, and build capacities are forwarded to harness the full potential of labor and retail platforms.

Full textAbstract:
This study analyzes the rise of the Miami startup ecosystem and the opportunities for mutual benefit engendered by a strong connection with Latin America and the Caribbean (LAC). The exponential technology revolution and the boom of the LAC startup ecosystem creates a massive opportunity to build a talent-driven network of startup and knowledge ecosystems that could generate trillions of dollars in value and millions of employment, while igniting the industries of the future across the Hemisphere. The recent rise of the Greater Miami area's innovation ecosystem opens the possibility to unleash value and growth through building a bridge that connects ecosystems across the Americas.

Full textAbstract:
In Latin America and the Caribbean (LAC), significant proportions of students struggle to attain basic competencies in reading and mathematics. To address this issue, traditional practices like grade repetition are prevalent, leading to delayed access to grade-level education and overcrowded classrooms. However, emerging research challenges the effectiveness of this approach. Instead, an innovative solution gaining traction is Accelerated Learning, rooted in neuroscience and psychology. It emphasizes learner-centered pedagogy, socioemotional development, and collaboration with families. EdTech platforms also present promising opportunities for learning acceleration. These approaches mark a paradigm shift towards holistic, student-centered learning solutions that aim to enhance educational outcomes and bridge learning gaps.

Full textAbstract:
In the United States, public transit ridership in 2020 declined by 79% compared to 2019 levels. With lockdowns implemented during the early days of the pandemic, direct human-to-human interactions migrated to virtual platforms (e.g., Facebook, Twitter, and Reddit). Social media platforms have aided researchers in answering numerous questions about current societal dilemmas, including COVID-19. This study investigates the public’s perception of transit systems via a social media analysis given the emergence of vaccines and other COVID-19 preventive measures. Findings revealed themes of fear and confusion concerning the use of public transportation during the pandemic. The public had doubts regarding the vaccines’ impact on transportation and movement throughout 2021, with most users concerned about the proliferation of new variants. Twitter users were concerned about the travel bans placed on African countries amidst the Omicron variant and urged the government to remove the bans. These findings will help bridge the gap between public health, transport, and commuter needs by helping transportation authorities and city planners better understand the social perception of transit systems during a pandemic.

Full textAbstract:
Climate change is a complex subject with terms and definitions that can seem overwhelming to non-specialists. What is ‘albedo’? What does ‘radiative forcing’ mean? What does ‘geoengineering’ entail? As climate change impacts grow more frequent and intense, it is critical that journalists, in particular, are equipped with the right information when they report. This set of open-access multilingual glossaries aim to bridge the gap between research and the general public by compiling this comprehensive list of most frequently-used terms related to climate change. A majority of these terms have been sourced from the different IPCC reports as well as public platforms such as the BBC and the Climate Reality Project.
