Abstract:
Offshore oil and gas platforms have a finite life of production operations. Once production ceases, decommissioning options for the platform are assessed. The role that a platform’s jacket plays as fish habitat can inform the decommissioning decision. In this study, conducted along the crossbeams of a California platform jacket and using an ROV, we compared estimates of fish diversity and densities determined from a targeted “biological” survey with those from a replicated “structural” survey. We found that the water column fish species assemblages characterized by the two methods were similar. By contrast, the two survey methods yielded different species assemblages inhabiting the crossbeam at the platform jacket base. This difference occurred because, at least off California, the platform jacket base species diversity tends to be highest where the bottom crossbeam is undercut, creating sheltering sites for many species. Because the structural method inadequately imaged the seafloor-crossbeam interface, particularly where a gap occurred between crossbeam and seafloor, substantial numbers of fishes were not visible. While we cannot extrapolate from this study to all platforms’ worldwide, it is clear that routine platform structural integrity surveys may be a valuable source for opportunistic marine community surveys. Intentional planning of the structural survey to incorporate relatively minor variations (e.g., maintaining fixed ROV distance from the infrastructure and consistent 90° camera angle) coupled with a deliberate consideration of the platform ecology (e.g., positioning the ROV to capture the seafloor-crossbeam interface) can substantially improve the effects on fish assemblage assessments from routine structural surveys without compromising the integrity assessment. We suggest that these biases should be both acknowledged and, understood when using routine structural surveys to inform platform ecology assessment. Additional consideration may be given to structural surveys that incorporate incremental adjustments to provide better data applicability to biological assessments.

Abstract:
The combined three-section crossbeam is an important component in the heavy gantry CNC milling-lathing machine tool and the dynamic characteristics are key precision factors for the machine tool. Three sections of the combined crossbeam are bolted by large industrial bolts and the influence of bolted joints should be evaluated in the dynamic analysis of the combined crossbeam. The dynamic characteristics of the combined three-section crossbeam were extracted by the modal experiment. The FEM of the monolithic crossbeam was modeled to analyze the dynamic characteristic parameters. The comparison of the analysis result and experimental result were shown. The experimental result matched well with the FEM of the monolithic crossbeam without bolted joints. As a result, the influence of the bolted joints could be ignorable in dynamic characteristic for the combined three-section crossbeam.

Abstract:
The crossbeam is one of the main supporting parts of large gantry CNC machines. The deformation of the crossbeam under loads at work has great impact on integrated machining errors of machines. However, the crossbeam assembly’s structure and the corresponding loads are so complex that it’s difficult to get them through experiences and analytic methods. In this paper, the FE statics analysis method is used to simulate and analysis of the crossbeam under six main working conditions, obtaining deformation and stress distribution of the crossbeam under each conditions. The results show that when the slippery saddle is at the middle of the crossbeam and the ram extends to 100% length (the distance between the end of ram and the bottom of slippery saddle is 1.29 m), the total deformation of the crossbeam assembly is 6.4914 × 10-5m, the maximum deformation is up to 3.4872 × 10-5m, and the maximum stress is 1.1882 × 107Pa appearing at the hole of the drive shaft. The design of the crossbeam can meet the work requirements well. And analysis results present a basis for further optimization analysis and structural improvements of the crossbeam.

Abstract:
The ultimate bearing capacity test is carried on CFST arch bridge model with CFRP slings, and the deflection of tie-beams, CFST arch, crossbeams, decks is also tested. Studies have shown that before the sliping of 4# CFRP sling, the deflection growth of east and west tie-beam, east and west arch both has good symmetry. The deflection growth of crossbeams and decks also has good symmetry, but after the sliping of 4# CFRP sling(located at the middle of west tie-beam), the structural internal forces redistribution appeared. The deflection of west tie-beam increased suddenly, and the mid-span deflection of west tie-beam is larger than that of east tie-beam by 14.6%. The mid-span deflection of east arch is larger than that of west arch by 9.9%. The deflection of crossbeam at 3L/8 and L/4 sections are respectively larger than those of crossbeam at 5L/8 and 3L/4 sections by 13.8% and 5.3%, The deflection of 3#, 2# and 1# decks are respectively larger than those of 4#, 5# and 6# decks by 7.8%, 13.2% and 17.1%. After the snapping of 10# CFRP sling(located at 3L/8 section of east tie-beam), the structural internal forces would appear redistribution. The deflection of east tie-beam would increase suddenly. The mid-span deflection of east tie-beam is larger than that of west tie-beam by 31.7%, and the mid-span deflection of east arch is larger than that of west arch by 21.3%. The deflection of crossbeam at 3L/8 and L/4 sections are respectively larger than those of 5L/8 and 3L/4 sections by 24.7% and 22.5%. The deflection of 3#, 2# and 1# decks are respectively larger than those of 4#, 5# and 6# decks by 16.2%, 24.5% and 28.6%.

Abstract:
The crossbeam is an important part in the gantry machining center which greatly affects the machining accuracy. Four kinds of crossbeam structure for the large machining center were designed and their static and dynamic characteristics were analyzed. The optimal crossbeam structure was selected by the comprehensive performance evaluation method. Then the thicknesses of rib plates in the crossbeam were defined as the optimization parameters after conducting the sensitivity analysis. The first four natural frequencies were defined as the objective functions and the static performance and the mass were defined as the constraint conditions. The optimal sizes of the rib plates in the crossbeam were obtained by the optimization analysis. Finally the feasibility of the result was demonstrated by the simulation. The result indicated that with the mass increased only by 0.18%, the first four natural frequencies of the optimal crossbeam were increased by 19.56%, 19.45%, 19.84%, 17.05%.

Abstract:
In SSCC floor systems the concrete slab is composite with both steel stringers and crossbeams or only with stringers. The horizontal bending of the crossbeams of SSCC floor systems is not ignorable. From the deformation conforming condition, theoretical formulas for SSCC floor systems of double-railway bridges with two stringers are developed. The factors which influence the horizontal bending of crossbeams are discussed. Some conclusions are obtained. When the width of the SSCC floor system is given, the main factors which influence the horizontal bending of the crossbeams are the axial stress of the lower chords, the distance between the side stringers and the lower chords, and the continuous length of SSCC floor system. Increasing the horizontal inertia moment of crossbeams almost cannot reduce the horizontal bending stress of crossbeams. A slight horizontal rotation of the lower joints such as 10-4 rad can release more than 3% crossbeam end horizontal bending moment.

Abstract:
Orthotropic decks are commonly used in high-speed railway bridges. Finite-element model is established by ANSYS for orthotropic steel bridge deck in this paper. Taking the standard PDL ZK live load as the train load, the local stress of the rib-to-deck joint, the rib-to-crossbeam joint, and the cut-outs of the crossbeam are analyzed respectively. Analysis results show that the stress concentration of bridge deck mainly appears at the intersecting part of the U-shaped rib, crossbeam, and bridge deck. In the whole bridge deck, the local stress level of the cut-outs in crossbeam is almost the highest, and the cut-outs is distorted seriously; the maximum stress of crossbeam cut-outs is mainly concentrated at the lower arc of the cut-outs, which is one of the positions prone to fatigue failure.

Abstract:
Abstract The theory of measuring crossbeam wind, shear, and turbulence within the radar’s resolution volume V6 is described. Spaced-antenna weather radar interferometry is formulated for such measurements using phased-array weather radar. The formulation for a spaced-antenna interferometer (SAI) includes shear of the mean wind, allows turbulence to be anisotropic, and allows receiving beams to have elliptical cross sections. Auto- and cross-correlation functions are derived based on wave scattering by randomly distributed particles. Antenna separation, mean wind, shear, and turbulence all contribute to signal decorrelation. Crossbeam wind cannot be separated from shear, and thus crossbeam wind measurements are biased by shear. It is shown that SAI measures an apparent crossbeam wind (i.e., the angular shear of the radial wind component). Whereas the apparent crossbeam wind and turbulence within V6 cannot be separated using monostatic Doppler techniques, angular shear and turbulence can be separated using the SAI.

Abstract:
Resistive Random Access Memories (ReRAMs) are amongst the most promising next generation memory technologies, due to their small feature size, low power consumption and capacity to be integrated in 3D ehen arranged in crossbar array. ReRAMs harvest the potential of the resistive switching phenomenon that allows to reversibly change their internal resistive state, from High to Low. This aspect, however, is also a problem when ReRAM cells are tesserated in crossbar array configuration: elements that are programmed in their low resistive state can create low resistance sneak paths in the array fabric making the readout operations strenuous. This challenge is usually mitigated by the use of selector devices. A selector must be able to suppress the currents owing in the sneak paths and, at the same time, allow for ReRAM reliable operations. In this work, the sneak current problem is introduced and defined. Several solutions that have been studied in literature are presented and discussed, creating a solid background for the development of this work. Upon this strong basis, different selector devices technologies were developed. Ni/TiO2/Ni selector devices were first designed, studied and benchmarked against other technologies showing improved performances in term of Voltage Margin without any adverse effect on the maximum current supplied. As this device stack has been designed to have a similar metal-insulator-metal architecture to ReRAM devices, the two were monolithically integrated and characterized. The possibility to exploit volatile resistive switching was also introduced and discussed thoroughly, starting from a TiO2/NiO stack exhibiting a promising threshold behaviour for selectorsoperations, fostering iterests of the community on this approach. The limitations of this approach were studied via SPICE simulations, setting the framework and requirements for their implementation in crossbars: through this ongoing work, it was realised that the selector technologies should not be evaluated in isolation from ReRAM, which has led to contributions towards forming-free ReRAM devices. This research stream employed a TiO2/AlOy bi-layer stack devices able to perform resisting switching with a 2-orders of magnitude ON/OFF ratio and low cycle-to-cycle variability without requiring electroforming: this behaviour is presented and discussed. Herein, overall this work has oered contributions towards reliable ReRAM/selector technologies operations for crossbar arrays in terms of both selector technology, improving existing approach and exploring new ones, and ReRAMs, providing the community with a promising path towards forming free operations.

Abstract:
L'écart de vitesse entre le processeur et la mémoire vive est devenu un point faible pour les performances des systèmes. En raison de ces limitations, de nombreuses mémoires émergentes ont été proposées comme solutions alternatives à ces problèmes existant dans la hiérarchie mémoire. Les mémoires résistives (RRAM) sont considérées comme des candidats pour la « storage class memory » (SCM), les mémoires non volatiles embarquées (eNVM), et les systèmes neuromorphique. Cependant, les problèmes de fiabilité tels que la rétention de données sont encore en cours d'amélioration. De plus, pour obtenir des matrices mémoires de grande densité, la RRAM a besoin des sélecteurs qui seront intégrer en série avec elle dans une architecture un-sélecteur une-résistance (1S1R). Le sélecteur est nécessaire avec le point mémoire pour éliminer les problèmes des courants de fuite, qui gênent le bon fonctionnement de la matrice mémoire dans des architectures crossbar et verticales 3D.Dans cette thèse, notre objectif principal est de traiter les défis ci-dessus. Notre travail peut être divisé en deux parties principales : i) l'étude de la fiabilité des cellules RRAM basées sur HfO2 et ii) la caractérisation des opérations de base et des performances des cellules RRAM basées sur HfO2 et qui sont co-intégrées avec deux types différents des sélecteurs. Pour la partie fiabilité, nous avons étudié les effets du dopage aluminium (Al) sur la rétention de données des cellules RRAM à base de HfO2. Des dispositifs à simple et double couche avec différentes concentrations d'aluminium ont été fabriqués et testés. A partir des comportements électriques macroscopiques, comme la dégradation du diélectrique en fonction du temps (TDDB) et l’opération de forming avec des rampes de tension, on a extrait des propriétés microscopiques des matériaux tels que l'énergie d'activation nécessaire pour la rupture d’une liaison chimique à champ nul et le moment dipolaire des liaisons dans les matériaux testés. En utilisant ces paramètres microscopiques nous avons effectué tout au long de ce travail des simulations physiques pour comprendre les dynamiques de l’opération de forming ainsi que les mécanismes physiques impliqués pendant les opérations du dispositif mémoire. Deuxièmement, nous avons étudié l'immunité aux rayonnements de la RRAM à base de HfO2 pour les applications spatiales. Nos dispositifs RRAM ont été exposés à une énergie de 266 MeV d'ions lourds d'iode. Des analyses pré- et post-exposition ont été effectuées sur les états de la mémoire et les tensions de programmation pour étudier les effets de l'irradiation sur les caractéristiques du dispositif mémoire.Dans la partie des dispositifs d’accès, nous avons évalué deux types différents des sélecteurs. Une forte non-linéarité dans les caractéristiques courant / tension est obligatoire pour effectuer une lecture précise et une écriture à faible consommation. Dans le premier dispositif étudié, la sélectivité est introduite en ajoutant une couche d'oxyde dans l’empilement mémoire et qui agit comme une barrière tunnel. Le principal avantage de cette méthode est la facilité d’intégration de la barrière tunnel, par contre elle souffre d'une faible sélectivité (~ 10) et d'un faible courant de programmation qui dégrade la rétention de données. Deuxièmement, on a co-intégré avec l’RRAM un sélecteur OTS et le dispositif 1S1R a été entièrement caractérisé. Le sélecteur OTS offre une plus grande sélectivité par rapport à la barrière tunnel avec les possibilités d'augmenter fortement cette sélectivité par l'ingénierie des matériaux chalcogénures. Plus de 106 cycles de lecture ont été obtenu pour les dispositifs 1S1R en utilisant une stratégie de lecture innovante que nous avons suggérée pour éviter les lectures perturbatrices et réduire la consommation d'énergie
The performance gaps in nowadays memory hierarchy on the first hand between processor and main memory, on the other hand between main memory and storage have become a bottleneck for system performances. Due to these limitations, many emerging memories have been proposed as alternative solutions to fill out such concerns. The emerging non-volatile resistive random-access memories (RRAM) are considered as strong candidates for storage class memory (SCM), embedded nonvolatile memories (eNVM), enhanced solid-state disks, and neuromorphic computing. However, reliability challenges such as RRAM thermal stability and resistance variability are still under improvement processes. In addition, to achieve high integration densities the RRAM needs two terminal selector devices in one-selector one-resistor (1S1R) serial cell. The BEOL selector device enables suppression of the parasitic leakage paths, which hinder memory array operation in crossbar and vertical 3D architectures.In this PhD, our main focus is to address and treat the above challenges. Here, the work can be divided into two main parts: i) the investigation of the reliability of HfO2 based RRAM cells and ii) the characterization of the basis memory operations and performances of HfO2 based RRAM cells co-integrated with two different back end of line (BEOL) selector technologies.For the reliability part, we have investigated the effects of aluminum (Al) doping on data retention of HfO2 based RRAM cells. Single and double layer devices with different aluminum concentration were fabricated and tested. From macroscopic electrical characteristics, like time dependent dielectric breakdown (TDDB) and ramped voltage forming, microscopic properties of the materials such as the activation energy to break a bond at zero field and the dipole moment of the bond were extracted. These parameters have been used to shed new light on the mechanisms governing the forming process by means of device level simulations. Second, we have addressed the radiation immunity of HfO2 based RRAM for possible space applications as well. Our RRAM devices were exposed to 266 MeV Iodine heavy ions energy. Pre- and post-exposure analysis were carried out on the memory states and the programming voltages to study the effects of the irradiation on the memory characteristics. Throughout this work, we have performed physics based simulations to understand the dynamics of the forming process as well as the physical mechanisms involved during the memory operations.For the access devices part, we have evaluated two different types of selectors. For accurate reading and low power writing a strong selectivity in the current/voltage characteristics is required. In the first studied device, the selectivity is introduced by adding an oxide tunnel barrier. The main advantage of this strategy is that it is easy to integrate, however it suffers of low selectivity (~10) and low programming current. Second, an OTS based selector co-integrated with HfO2 based RRAM was fully characterized. OTS selector provides higher selectivity compared to the oxide tunnel barrier with the possibilities to strongly increase this selectivity by material engineering. Over 106 read cycles have been achieved on our 1S1R devices using an innovative read strategy that we have suggested to prevent disruptive read and to reduce the power consumption

Abstract:
<p>Longitudinal ribs with the trapezoidal section are broadly adopted in orthotropic steel decks especially for long span bridges. When the tire load is eccentric from the axis of the rib, the torsional rigidity of ribs is critically reduced by distortion which impedes the horizontal dispersal of load. Because of the existence of cutouts in crossbeam, the high stress concentration at the rib-to-crossbeam joint caused by the rib distortion makes the joint easily prone to fatigue damage. In this paper, based on the parametric analysis of several classical design parameters, static load experiments of an orthotropic steel deck specimen are performed. Measurement results support the positive correlations between the weld length of rib-to-crossbeam joint and the distortional stress. The most unfavorable load position of stress concentration induced by rib distortion is also verified, which is about 1600 mm away from the investigated crossbeam. Experimental results indicate that ribs are deformed toward different directions at the midspan section and the crossbeam section separately when the load is eccentric from the axis of rib.</p>

Abstract:
Abstract Increased insight into the internal structure of microelectronic devices can be achieved through the use of three dimensional (3D) imaging based on image stacks of serial sections obtained with a combined electron and ion beam (CrossBeam) FIB. This study describes how such data can be collected and presented, some of the factors that need to be optimized to get the best images, and the limitations of the method. It can be viewed as a first step in the emerging area of high resolution 3D microscopy, a technique that can lead to more accurate characterization of the shapes of internal structures and their interconnectivity at the nanoscale.

Abstract:
<p>A cable-stayed bridge, whose main span is 230 m, is a four-line railway steel truss bridge. It is the first time to use only two main trusses in four-line railway truss bridge. In order to solve the transfer problem of wide truss-deck system and the design of the horizontal deck-beam, auxiliary longitudinal beams and horizontal K-bars are installed near lower chords of main truss. This is an innovative deck system, and we need to research on the structure performance. In this paper, the comparative analysis between the new type of deck system with horizontal K-bars and the traditional deck system with multi-crossbeam were carried out by FEM which focus on the deck structural characteristics, system stiffness, local deformation, etc. Also, in order to carry out the model test, a scale segmental experimental model of deck structure with horizontal K-bars was designed and manufactured. The FEM results show that: the bridge deck system with horizontal K- shaped braces is better than the multi-crossbeam deck system in structural stiffness, local deformation, participating rate of longitudinal force. And, the experimental results were in good agreement with the results of FEM analysis, which verified the correctness of FEM results and the rationality of design. The working condition of the bridge is good since opened on December 26, 2014.</p>
