Diffusion imaging and tractography enable mapping structural connections in the human brain, in-vivo. Linear Fascicle Evaluation (LiFE) is a state-of-the-art approach for pruning spurious connections in the estimated structural connectome, by optimizing its fit to the measured diffusion data. Yet, LiFE imposes heavy demands on computing time, precluding its use in analyses of large connectome databases. Here, we introduce a GPU-based implementation of LiFE that achieves 50-100x speedups over conventional CPU-based implementations for connectome sizes of up to several million fibers. Briefly, the algorithm accelerates generalized matrix multiplications on a compressed tensor through efficient GPU kernels, while ensuring favorable memory access patterns. Leveraging these speedups, we advance LiFE’s algorithm by imposing a regularization constraint on estimated fiber weights during connectome pruning. Our regularized, accelerated, LiFE algorithm (“ReAl-LiFE”) estimates sparser connectomes that also provide more accurate fits to the underlying diffusion signal. We demonstrate the utility of our approach by classifying pathological signatures of structural connectivity in patients with Alzheimer’s Disease (AD). We estimated million fiber whole-brain connectomes, followed by pruning with ReAl-LiFE, for 90 individuals (45 AD patients and 45 healthy controls). Linear classifiers, based on support vector machines, achieved over 80% accuracy in classifying AD patients from healthy controls based on their ReAl-LiFE pruned structural connectomes alone. Moreover, classification based on the ReAl-LiFE pruned connectome outperformed both the unpruned connectome, as well as the LiFE pruned connectome, in terms of accuracy. We propose our GPU-accelerated approach as a widely relevant tool for non-negative least squares optimization, across many domains.

Abstract Attention-deficit/hyperactivity disorder (ADHD) has been conceptualized as a brain dysconnectivity disorder. In the past decade, noninvasive diffusion magnetic resonance imaging (dMRI) studies have demonstrated that individuals with ADHD have alterations in the white matter structural connectome, and that these alterations are associated with core symptoms and cognitive deficits in patients. This review aims to summarize recent dMRI-based structural connectome studies in ADHD from voxel-, tractography-, and network-based perspectives. Voxel- and tractography-based studies have demonstrated disrupted microstructural properties predominantly located in the frontostriatal tracts, the corpus callosum, the corticospinal tracts, and the cingulum bundle in patients with ADHD. Network-based studies have suggested abnormal global and local efficiency as well as nodal properties in the prefrontal and parietal regions in the ADHD structural connectomes. The altered structural connectomes in those with ADHD provide significant signatures for prediction of symptoms and diagnostic classification. These studies suggest that abnormalities in the structural connectome may be one of the neural underpinnings of ADHD psychopathology and show potential for establishing imaging biomarkers in clinical evaluation. However, given that there are inconsistent findings across studies due to sample heterogeneity and analysis method variations, these ADHD-related white matter alterations are still far from informing clinical practice. Future studies with larger and more homogeneous samples are needed to validate the consistency of current results; advanced dMRI techniques can help to generate much more precise estimation of white matter pathways and assure specific fiber configurations; and finally, dimensional analysis frameworks can deepen our understanding of the neurobiology underlying ADHD.

AbstractDiffusion magnetic resonance imaging and tractography enable the estimation of anatomical connectivity in the human brain, in vivo. Yet, without ground-truth validation, different tractography algorithms can yield widely varying connectivity estimates. Although streamline pruning techniques mitigate this challenge, slow compute times preclude their use in big-data applications. We present ‘Regularized, Accelerated, Linear Fascicle Evaluation’ (ReAl-LiFE), a GPU-based implementation of a state-of-the-art streamline pruning algorithm (LiFE), which achieves >100× speedups over previous CPU-based implementations. Leveraging these speedups, we overcome key limitations with LiFE’s algorithm to generate sparser and more accurate connectomes. We showcase ReAl-LiFE’s ability to estimate connections with superlative test–retest reliability, while outperforming competing approaches. Moreover, we predicted inter-individual variations in multiple cognitive scores with ReAl-LiFE connectome features. We propose ReAl-LiFE as a timely tool, surpassing the state of the art, for accurate discovery of individualized brain connectomes at scale. Finally, our GPU-accelerated implementation of a popular non-negative least-squares optimization algorithm is widely applicable to many real-world problems.

The human brain is a complex container of interconnected networks. Network neuroscience is a recent venture aiming to explore the connection matrix built from the human brain or human “Connectome.” Network-based algorithms provide parameters that define global organization of the brain; when they are applied to electroencephalographic (EEG) signals network, configuration and excitability can be monitored in millisecond time frames, providing remarkable information on their instantaneous efficacy also for a given task’s performance via online evaluation of the underlying instantaneous networks before, during, and after the task. Here we provide an updated summary on the connectome analysis for the prediction of performance via the study of task-related dynamics of brain network organization from EEG signals.

Abstract INTRODUCTION Low-grade gliomas (LGGs) are slow growing tumors that often cause infiltration and/or compression of the white matter pathways. Regular imaging modalities are no capable of revealing such a pathologic condition. Furthermore, up-to-date there is no reliable noninvasive imaging method to address this issue. Here we report that the local connectome fingerprint, an along track density measurement derived from diffusion MRI (dMRI), is capable of revealing the tumor compression effect on the surrounding white matter pathways. METHODS We acquired high angular resolution dMRI data on 16 patients diagnosed of LGG (WHO grade II). Peritumoral fiber tracts underwent qualitative and quantitative evaluation. Contralateral hemisphere counterparts were used for comparison. The local connectome fingerprint of peritumoral tract segment and their ratio to healthy side were visualized and calculated in comparison with 842 normal subjects from the Human Connectome Project. RESULTS >Our results showed significant increase in the ratios to the normal side among displaced tracts and decreases among the infiltrated tracts when compared to their healthy counterpart. Qualitative analysis of 65 peritumoral tracts revealed 9 (13.8%) unaffected, 24 (36.9%) displaced, 13 (20%) infiltrated and 19 (29.2%) tracts with a combination of displacement and infiltration. There were no disrupted tracts. The along tracks local connectome fingerprint further localizes the track segments with compression effect caused by the tumor mass. This feature cannot be observed in conventional tensor and diffusivity analysis. CONCLUSION The unique capability of local connectome fingerprint in revealing the compression and infiltration effect can provide potential diagnostic and prognostic applications in clinical intervention of patients with WHO grade-II low-grade gliomas.

Abstract BACKGROUND Radiomics and connectome analysis are distinct and non-invasive methods of deriving biologic information from MRI. Radiomics analyzes features intrinsic to the tumor, and connectomics incorporates data regarding the tumor and surrounding neural circuitry. In this study we used both techniques to predict glioma survival. METHODS We retrospectively identified 305 adult patients with histopathologically confirmed WHO grade II–IV gliomas who had presurgical, 3D, T1-weighted brain MRI. Available clinical variables included tumor lobe, hemisphere, multifocal nature grade, histology extent of surgical resection, patient age gender. For connectomics, we calculated nodal efficiencies, network size and degree for all pairs of 33 voxel cubes spanning the entire gray matter volume using similarity-based extraction and graph theory. Radiomic features were extracted using Pyradiomics and subjected to patient-level and population-level clustering (N=172). These clusters were then used to construct a multi-regional spatial interaction matrix for model building. Cox proportional hazards models were fit for clinical variables alone, connectomics alone, radiomics alone, connectomics+clinical and radiomics+clinical. We implemented 10-folds cross-validation and examined the mean area under the curve (AUC) across validation loops. RESULTS Median survival time was 134.2 months. The mean AUC for the clinical model was 0.79 +/- 0.01, the connectome model was 0.88 +/- 0.01, the combined connectome + clinical model was 0.93 +/- 0.01, the radiomic model was 0.64 +/- 0.05 and the radiomics+clinical model was 0.89+/-0.03. Radiomic analysis of the entire dataset as well as comparisons of radiomic+connectomics +/- clinical models are pending. CONCLUSIONS The combination of clinical variables and connectome analysis provided a more robust predictive model than other models. This suggests that connectome analysis incorporates valuable clinically-predictive information which can augment our capacity for prognostication of patients with diffuse glioma. These methods warrant further evaluation in larger prospective study of patients with diffuse glioma.

The presented literature review is devoted to the assessment of the brain connectivity using specialized magnetic resonance imaging (MRI) techniques — resting state functional MRI and MR tractography, and the possibilities of their use in the rehabilitation of patients with multiple sclerosis (MS).MS is the leading cause of non-traumatic neurological disability in young adult patients in the Russian Federation, and its prevalence continues to grow steadily. The use of complex neurorehabilitation is the basis to improve the better functional outcome of patients suffering from this disease.At the same time, in clinical practice, the evaluation of the effectiveness of rehabilitation results is carried out purely on the basis of clinical scales. Resting state functional magnetic resonance imaging (rs-fMRI) makes it possible to identify connections between various functionally related regions of the brain without any external stimulation, as well as to assess the state of the connectome in dynamics.This review article discusses the main directions of modern methods of neurorehabilitation, assesses impairments in the DTI and rs-fMRI measurments in patients with multiple sclerosis compared with healthy volunteers, as well as changes in these parameters over time after the use of various neurorehabilitation methods aimed at restoring motor and cognitive functions.

Background: The gender differences in the brain anatomy play an important role in planning and analysis in a lot of studies of the brain. Despite most animal studies being performed on the animals of only one sex, clinical studies generally enroll both males and females. Keeping this fact in mind, learning the gender differences in the white matter structure is important for those studies which deal with the white matter changes. These differences should be considered on the stages of planning and evaluation of the results. Aims: Evaluation of the gender differences in the white matter pathways in healthy subjects. Methods: 21 women and 20 men were enrolled in the study. All the subjects underwent MR-tractography, then the anatomic connectome was composed and the differences were evaluated using the tracts quantitative anisotropy (QA) evaluation. Results: The gender differences were found in the white matter pathways with the prevalence of quantitative anisotropy in women, observed in a larger number of tracts than in those of men. QA was prevalent in a lot of fascicli that form major pathways in both groups: corpus callosum, dominant arcuate fasciclus, inferior fronto-occipital, inferior and superior right longitudinal pathways. Conclusions: The white matter pathways in males and females are different not only within the major tracts but also for small fascicli that form tracts.

Streszczenie:
Due to the weakness of the connections between woodframe and stucco, a large number of woodframe residential buildings with stucco as a shear resisting member were damaged during past earthquakes. This has resulted in the shear resistance of stucco being reduced in a number of building codes. A number of research projects have been conducted on stucco shear walls since then and the results from all research projects indicated that stucco separates from the wood frame due to the weakness of the connections between the wood frame and stucco when subjected to lateral cyclic loading. On the other hand, when properly attached to wood frame, stucco can have a significant contribution to the stiffness of the structure. A special connector was developed to provide direct shear connection between stucco and woodframe structures. The device is designed to have adequate stiffness and strength, and to act as a ductile “fuse” so that stucco shear walls will have a well defined strength and significant ductility. As part of the current research project, numerous tests were conducted on stucco-connector-woodframe elements to study the shear connectors, and provide important design information. Tests were also conducted on 8 ft by 8 ft stucco wall panels with and without the special connectors. The tests show that stucco shear walls with the connectors have much greater shear strength and ductility than regular stucco walls. The tests also show that stucco walls with the shear connectors can achieve similar strengths and similar ductility as plywood shear walls.

The use of deck fasteners as shear connectors for composite open web steel joists is studied. Results of thirty-six push-off tests are evaluated in terms of strength and behavior. Six types of deck fasteners are considered. They are: 1. #12-24 Teks/5 self-drilling, self-tapping screws. 2. 1/4-14 Teks/3 with a 1 1/4 in. stand-off sleeve. 3. 1/4-14 Teks/3 with a 1 3/4 in. stand-off sleeve. 4. 1/4-14 Teks/3 with a 2 1/4 in. stand-off sleeve. 5. 0.150 in. dia. air fired pins. 6. Puddle welds (5/8 in. and 3/4 in. diameter). All push-off tests utilize Vulcraft 1.5 VL, 22 gage, composite deck. Several modifications to the typical push-off test arrangement are made, which will permit the test to more closely model the top chord of an open web steel joist. It was found from the push-off test results that all of the deck fasteners, tested in this study, can obtain composite action for snort span open web steel joists with the exception of 0.150 in. diameter air fired pins. A description and the results of each push-off test is included.

Hurricane Charley was the third named storm and the second major hurricane of the 2004 Atlantic hurricane season. At that time, it was also the strongest hurricane to strike the US coast since 1992. Charley made landfall on Friday, August 13, 2004 on the barrier islands off Lee County, Florida whence it moved rapidly inland towards Port Charlotte, DeSoto and Hardee counties. The purpose of this study was to understand the performance of undamaged residential home in Punta Gorda Isles (PGI) in Port Charlotte County that was crossed by Charley’s eye shortly after it made landfall. To achieve this goal, a representative sample of 20 undamaged residential homes (out of 210 identified in an earlier study) in PGI were selected from aerial photographs for detailed analysis. Unfortunately, information on dimensions of these buildings could not be obtained despite repeated attempts over a 6-month period. Consequently, a parametric study was conducted using an idealized building following procedures consistent with current practice. In the analysis, parameters such as wind velocity, exposure and building geometry were varied to assess the range of design forces. The maximum wind velocity was taken as 160 mph, based on findings reported in FEMA 488. Two idealized roof systems – a gable and hip – on a rectangular plan form were analyzed using ASCE 7-98’s Method 2. Both Main Wind Force Resisting System (MWFRS) and Components and Cladding (C&C) were evaluated. The results showed that forces resisted were significantly (over 70%) higher than those designed for. Since 210 out of 425 homes studied earlier were undamaged it suggests that properly constructed structures automatically have adequate reserve capacity to withstand higher-than-designed for lateral loads. If changes are needed, it should focus on inspection and construction rather than wind provisions in existing code.

Remarkable progress has been made in the development of effective treatments for patients with rheumatoid arthritis (RA). To ensure that a patient is optimally responding to treatment, consistent monitoring of disease activity is recommended. Established composite and individual disease activity measures often cannot be computed due to missing laboratory values. Simplified measures that can be calculated without a lab value have been developed and previous studies have validated these new measures, yet differences in their performance compared with established measures remain. Therefore, the goal of my doctoral research was to examine and evaluate disease activity and composite measures to facilitate monitoring of response in clinical care settings and inclusion of patients with missing laboratory values in epidemiological research. In the first study, the validity of two composite measures, the Clinical Disease Activity Index (CDAI) and the Disease Activity Score with 28 joint count (DAS28) was examined and both were significantly associated with a rheumatologist’s decision to change therapy (CDAI OR=1.58; 95% CI: 1.42, 1.76) (DAS28 OR=1.34; 95% CI 1.27,1.56). However, further evaluation using receiver operating characteristic (ROC) analysis found that they were not strong predictors of physician decisions to change therapy (AUC=0.75, 0.76, respectively). Thus, they should not be used to guide treatment decisions in the clinic. Two measures of disease activity, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are often not measured and impede the computation of composite measures of disease activity. In the second study, significant factors which may predict the measurement of the ESR and CRP were identified and included physician and clinical variables but no quantitative disease activity measures. Thus the suitability of the ESR and CRP as measures of disease activity is suspect. In the final study, I created a new composite measure, the modified disease activity score with 28 joint count (mDAS28), by replacing the laboratory value in the DAS28. The mDAS28 was then validated by comparing its performance with the DAS28. The measures were strongly correlated (r=0.87), and strong agreement was found between the two measures when categorizing patients to levels of disease activity (ĸ=0.77) and treatment response (ĸ=0.73). Therefore, the mDAS28 could be used in place of the DAS28 when laboratory values needed to compute the DAS28 are missing. In summary, I found that the CDAI and DAS28 were not strong predictors of the rheumatologist’s decision to change therapy. I also found that the variability in the measurement of ESR and CRP was not associated with disease activity. I was able to modify the DAS28 by replacing the laboratory measure and create a new simplified measure, the mDAS28. I also validated the mDAS28 for use in the clinic and in epidemiological research when the DAS28 is unavailable.

An innovative shear connector, Wave-Perfobond Shear Connector (W-PSC), was experimentally evaluated to study its structural behaviors of shear strength and ductility. Perfobond is a traditional steel plate with holes used as a shear connector. The steel plate used for the Wave-perfobond is a wave shape. The experimental program consisted of seven test specimens which were conducted push out test in accordance with the Eurocode 4. The design parameters of the specimens included ratio of wave amplitude to wavelength, extension, holes, and lateral reinforcement inside of the hole. The test results demonstrated that the W-PSC had better shear strength and ductility than traditional perfobond. With larger ratio of wave amplitude to wavelength, the W-PSC achieved higher shear strength but poorer ductility because of the large bearing area. Extensions at both ends of the W-PSC provided extra shear strength and more stable behavior after peak load. Unlike flat steel plate, the wave-steel plate without hole reached higher strength and better ductility than wave-steel plate with hole. Because of the dowel, the transverse reinforcing bar inside the hole of the W-PSC effectively enhanced the shear strength. Because the W-PSC is superior in shear strength and ductility, this study verifies that the W-PSC is an excellent shear connector.

As economic development between China and Taiwan, most traditional and labor intensive industries have had transferred to China extensively. However, the quality control level of their suppliers is more uneven than ever, which causes extra costs from rework and replacement. What is worse, someone’s fault in overheat of battery used in notebook computer has damaged its customers’ reputation seriously. Hence, electronic industries ought to choose suppliers for better competitiveness when faced with tremendous change. The purpose of this research is to help electronic industries construct a performance evaluation of connector suppliers. In the beginning, it collects related papers concerning connectors and performance as basis; then, surveys status quo of connector industries in Taiwan. Making use of five perspectives quoted from balanced scorecard (BSC), except for financial capability, customer service capability, process capability, learning and growth capability, the research modifies the perspectives into five by adopting flexibility response capability. Also, it searches for proper and positive performance evaluation method for connector purchasers by means of expertise survey and weighted indicators computed by analytic hierarchy process (AHP). The result of this research can offer not only performance evaluation for electronic companies to purchase connectors, but also infrastructure for further study of suppliers’ competitive strategy.

AbstractMoGym, is an integrated toolbox enabling the training and verification of machine-learned decision-making agents based on formal models, for the purpose of sound use in the real world. Given a formal representation of a decision-making problem in the JANI format and a reach-avoid objective, MoGym (a) enables training a decision-making agent with respect to that objective directly on the model using reinforcement learning (RL) techniques, and (b) it supports rigorous assessment of the quality of the induced decision-making agent by means of deep statistical model checking (DSMC). MoGym implements the standard interface for training environments established by OpenAI Gym, thereby connecting to the vast body of existing work in the RL community. In return, it makes accessible the large set of existing JANI model checking benchmarks to machine learning research. It thereby contributes an efficient feedback mechanism for improving in particular reinforcement learning algorithms. The connective part is implemented on top of Momba. For the DSMC quality assurance of the learned decision-making agents, a variant of the statistical model checker modes of the Modest Toolset is leveraged, which has been extended by two new resolution strategies for non-determinism when encountered during statistical evaluation.

AbstractIn an Industrie 4.0 (I4.0), rigid structures and architectures applied in manufacturing and industrial information technologies today will be replaced by highly dynamic and self-organizing networks. Today’s proprietary technical systems lead to strictly defined engineering processes and value chains. Interacting Digital Twins (DTs) are considered an enabling technology that could help increase flexibility based on semantically enriched information. Nevertheless, for interacting DTs to become a reality, their implementation should be based on open standards for information modeling and application programming interfaces like the Asset Administration Shell (AAS). Additionally, DT platforms could accelerate development and deployment of DTs and ensure their resilient operation.This chapter develops a suitable architecture for such a DT platform for I4.0 based on user stories, requirements, and a time series messaging experiment. An architecture based on microservices patterns is identified as the best fit. As an additional result, time series data should not be integrated synchronously and directly into AASs, but rather asynchronously, either via streams or time series databases. The developed DT platform for I4.0 is composed of specialized, independent, loosely coupled microservices interacting use case specifically either syn- or asynchronously. It can be structured into four layers: continuous deployment, shop-floor, data infrastructure, and business services layer. An evaluation is carried out based on the DT controlled manufacturing scenario: AAS-based DTs of products and manufacturing resources organize manufacturing by forming highly dynamic and self-organizing networks.Future work should focus on a final, complete AAS integration into the data infrastructure layer, just like it is already implemented on the shop-floor and business services layers. Since with the standardized AAS only one interface type would then be left in the DT platform for I4.0, DT interaction, adaptability, and autonomy could be improved even further. In order to become part of an I4.0 data space, the DT platform for I4.0 should support global discovery, data sovereignty, compliance, identity, and trust. For this purpose, Gaia-X Federation Services should be implemented, e.g., as cross-company connectors.

Drug resistant epilepsy (DRE) is not an uncommon clinical condition. DRE could cause disabling seizures and even sudden unexpected death in epilepsy (SUDEP). Pre-surgical evaluation is necessary to for surgical treatment to cure or palliative epilepsy. If feasible, surgical excision of an epileptic focus provides the best chance of cure. However, the standard non-invasive workup could not always identify the epileptic focus. Stereotactic EEG (SEEG) is an invasive EEG that could provide the spatial and temporal progression of epileptic discharge so that we could localize or lateralise the epileptic focus more easily. This chapter aims to illustrate the principle of SEEG, the methods of SEEG electrode insertion, the usual white matter tract pathway that epileptic discharge progresses. It also discusses the therapeutic use of SEEG in lesioning with radiofrequency ablation (RFA), as well as the future potential as part of the brain-computer interface (BCI).

The design rules for clamped connections in the ASME Boiler and Pressure Vessel Code (Section VIII, Div. I, Appendix 24) were developed for two-segment clamp connectors and must be modified to accommodate alternative clamp configurations. Developing a simplified rule-based model for predicting three-segment pipe clamp connectors (3-PCC)connector pressure capacities will greatly simplify the evaluation of 3-PCC connectors. The first goal of this paper is to develop a general parametric design rule set for multiple-clamp-segment pipe by expanding upon the published requirements of the ASME Boiler and Pressure Vessel Code for two-segment pipe clamp connectors and pipe flanges using basic principles. The next goal is to apply the design rule set to a typical 3-PCC design and to summarize the rules. The results of this paper provide a parametric rule-based approach to evaluating the pressure capacity of a 3-PCC. This paper has been developed in partial fulfillment of the requirements for the Master’s Degree Program at Washington State University.

Vibration-induced fretting degradation is widely known as a major problem for electrical connectors. At present, much of the evaluation of fretting propensity for particular connector designs and the influence of variations in those designs on fretting performance is conducted through exhaustive experimental testing. Therefore, a simulation based method to predict the influence of various design factors would be beneficial to those responsible for connector design and application. In the authors’ previous work, a combined experimental and modeling study of vibration-induced fretting degradation was conducted for a single blade/receptacle connector pair. However, in actual application, multiple pin connector system are typically used. Thus, studying a complete connector system is an appropriate next step in investigating the relative influence of connector system characteristics on fretting degradation. In this study, a simplified 2-D model was developed using ABAQUS. A series of parallel simulation and corresponding experiments were performance. Good correlation between the experimentally observed results and those predicted by the models was observed.

The objectives of this paper are to determine the structural and functional bending capacity, for an 18-3/4 inch 10 ksi Dry Completion Unit (DCU) external tieback connector (ETBC), utilizing more advanced analysis design verification procedures of API 17TR8 [1]. This requires the evaluation using a 3D nonlinear elastic-plastic finite element analysis (FEA). Although the design verification procedures of API 17TR8 [1] are written for high pressure high temperature (HPHT) equipment, this paper demonstrates the feasibility of applying it to lower pressure equipment which have more critical requirements for bending capacity vs. pressure capacity. The capacity results are compared between the existing linear elastic criteria of API 17G [2] and the requirements of API 17TR8 [1]. The application of this evaluation demonstrates that the analysis methodology for HPHT equipment can be applied to subsea tieback connectors to obtain maximum bending capacity of the connection.

Abstract Recently, companies have been experimenting with parallel-mechanism based approaches for milling machines. This research presents an investigation into the development of a special 6-6 parallel mechanism for application to contour milling. The idea behind this approach is that existing non-CNC milling equipment can be augmented to increase its capability at a lower cost than purchasing traditional 5-axis machining centers. This paper presents the phase of research associated with developing a parametric kinestatic design methodology for a special 6-6 parallel mechanism (Kinestatic Platform, KP). This methodology was applied to the design specifications associated with 5-axis contour milling. The resulting kinestatic design’s dynamics were evaluated to determine the actuation requirements of each connector. A prototype connector was built to allow the evaluation of actuator response under simulated loading conditions. Joint stiffness and control strategy were of primary concern in evaluating the performance of the prototype connector. The parametric kinestatic design and control strategy results are presented. Several observations are evidenced from the research. Joint deflection is an obvious critical issue and the most difficult to quantify. A scheme is proposed detailing the concept of using a separate metrology frame to overcome difficulties associated with accurate connector length determination.

In the late 2006, as a part of its GoM HPHT technology program, BP initiated with V&M the design and qualification of a 15k dual barrier dry tree production riser system capable of being installed in water depths up to 10,000 ft. This was driven by the fact that X-80 riser systems became so heavy that they were not considered workable, whereas switching to higher strength steel and T&C connector designs made the systems much lighter and became enabling technologies for dry trees. Developments concern an 11 3/4″ OD with 1.1″ wall thickness C-110 sour service resistant material as the inner riser rated to 15k, a 16″ OD with 1″ wall thickness Q-125 material as the outer riser rated to 10k, and a 21″ OD with 1″ wall thickness Q-125 material as the drilling riser rated to 10k. The specification called for all three connections to be designed with an external environmental metal to metal seal, and superior fatigue performance. Based on existing know-how on fatigue resistant T&C connectors, the development work started with the 11 3/4″ inner riser, with a need to accommodate existing design rules for such a heavy pipe. A comprehensive evaluation program was built, with a total of 39 samples including 5 design variations, and full scale tests combining Make & Break, sealability, fatigue, and thermal cycles. The qualification was completed with a connector achieving over 25 M&B and a stress factor less than 1.5 compared to DNV-B1 curve, that is a stress factor matching DNV-C. With success on the 11 3/4″ and some lessons learned along the way, focus was then shifted to the 16″ outer riser. Key issues were identified here concerning the surface treatment quality of the metal to metal seals when combining large sliding distance and high contact pressure. The 21″ drilling riser development is on-going. As we near full product qualification, we focus on final optimizations to ensure easy field running. This paper will prove the robustness of the design process elaborated to develop heavy wall riser T&C premium connectors, leading to outstanding fatigue performance and fatigue compliant internal and external environmental metal to metal seals. Such results prove the applicability of T&C for dry tree HPHT systems, and further establish the potential of T&C to be used for SCR and Flowline applications.

Streszczenie:
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.
