Abstract:

In this paper, we present a comprehensive investigation of the influence of pipeline configurations on the performance of ASIC implementations of the Advanced Encryption Standard (AES) substitution box (S-box) based on a composite field structure. We consider pipeline configurations for the S-box with a typical composite field structure by varying the number of pipeline stages and the placement approach of pipeline registers. Besides the conventional placement approach at the component level of the S-box, we adopt a new placement approach at the gate level to achieve a fine-grained pipeline. T

Abstract:

Although twin pipelines in series have been used to transport hydrocarbons in engineering practice, most previous studies focused on the dynamic response of the seabed around a single pipeline. A two-way coupling model of fluid–structure–seabed interaction (FSSI) is proposed for the study of the soil response and liquefaction caused by waves and currents around twin pipelines. The present model integrates the flow model and the seabed model by introducing a boundary condition of velocity continuity in addition to the continuity of pressures at the seabed surface. Then, the inconsistency betwee

Abstract:

This paper proposes a digital self-calibration technique for pipelined ADC. In this technique, the pipelined ADC is composed of a series of cyclic ADCs and each stage has independent digital self-calibration. Because of this, our technique achieves higher accuracy calibration than the conventional method that calibrates by using later stages. Applying the proposed method, we simulated the pipelined ADC with MATLAB and showed that higher accuracy calibration can be achieved with a smaller number of pipeline stages.

Such condition, the pipelines are subjected to axial compressive forces which will cause the pipelines to expand, consequently the pipelines tend to buckle for certain size and distance from the initial of pipeline.

Equally difficult are policy maintenance and refactoring, as well as porting a configuration from one firewall system to another.

Flow visualization tests confirmed that the horizontal velocities were about the same as those that would be found on a flat bed with the same total depth.

Abstract:

Abstract Affected by external loads or pipeline corrosion, oil & gas transmission pipelines may encounter safety hazards during service. In terms of defect repair, both domestic and foreign standards currently stipulate that the permanent repair method is B-type sleeve or tube replacement. Compared to the costly tube replacement, B-type sleeves are undoubtedly the preferred choice for economy and safety. However, due to installation size limitations, conventional sleeves are difficult to repair large deformation defects such as wrinkles and buckling in oil and gas pipelines. This study aim

AbstractThis paper presents the cognitive module of the Cognitive Architecture for Artificial Intelligence (CAAI) in cyber-physical production systems (CPPS). The goal of this architecture is to reduce the implementation effort of artificial intelligence (AI) algorithms in CPPS. Declarative user goals and the provided algorithm-knowledge base allow the dynamic pipeline orchestration and configuration. A big data platform (BDP) instantiates the pipelines and monitors the CPPS performance for further evaluation through the cognitive module. Thus, the cognitive module is able to select feasible a

Abstract:

GitHub Actions and Jenkins are both Continuous Integration/Continuous Delivery (CI/CD) tools that can create CI/CD pipelines in various environments and ecosystems, including the Google Cloud Platform (GCP). Jenkins is an open-source, older, and more comprehensive tool requiring significant skills and effort. GitHub Actions is simpler and closely tied to the GitHub platform. This article compares the two tools in ten dimensions: workflow definition and configuration, scalability and performance, authentication, security and monitoring, cost management, community, ecosystem and plugin support,

Abstract:

Image processing systems are widely used in space applications, so different radiation-induced malfunctions may occur in the system depending on the device that is implementing the algorithm. SRAM-based FPGAs are commonly used to speed up the image processing algorithm, but then the system could be vulnerable to configuration memory errors caused by single event upsets (SEUs). In those systems, the captured image is streamed pixel by pixel from the camera to the FPGA. Certain local operations such as median or rank filters need to process the image locally instead of pixel by pixel, so some pa

Abstract With modular automation, modular industrial plants use a functional engineering approach, and modules enable plug & produce plant engineering. However, plant configuration is still a largely manual process and often not optimized with respect to the available information. In this contribution, we propose a system and algorithm to support the automation engineer in the process of joining together modules into process pipelines and in their optimization. Our solution is built upon an abstract semantic data model that facilitates the automated matching of pre- and post-condition of m

Abstract To identify the condition of steel pipelines beyond the line of sight during operation, this study presents a design methodology for a differential probe, along with a harmonic magnetic field excitation technique and its corresponding data processing methodology. The coaxial arrangement of the excitation coils in a planar configuration generates a potent induced magnetic field, ensuring a sufficient standoff distance. Under the influence of harmonic excitation, the magnetic permeability of the pipeline surface decreases, resulting in an increased detection depth. Periodic alterations

Abstract:

The most commonly used subsea pipeline installation method is the S-Lay method. A very important and complex task in an S-Lay installation engineering analysis is to find the optimal pipelay vessel installation configuration for every distinctive pipeline route section. Installation loads in the pipeline are very sensitive to small changes in the configuration of the pipeline supports during laying and other influential parameters, such as the tensioner force, stinger angle, trim and draft of the pipelay vessel. Therefore, the process of an engineering installation analysis is very demanding,

AbstractCaging grasps limit the mobility of an object to a bounded component of configuration space. We introduce a notion of partial cage quality based on maximal clearance of an escaping path. As computing this is a computationally demanding task even in a two-dimensional scenario, we propose a deep learning approach. We design two convolutional neural networks and construct a pipeline for real-time planar partial cage quality estimation directly from 2D images of object models and planar caging tools. One neural network, CageMaskNN, is used to identify caging tool locations that can support

Three different configurations are investigated: (i) cooling the compressed gas, (ii) no cooling and (iii) line heating immediately after the compressor station. For each c

Related, but serving a very different function, is the role of pipeline companies in their various business models to transport that gas to market. This is a different and equally robust and growing segment of the natural gas industry where large amounts of shale exploration take place. In fact, without pipelines an

Abstract:

In this paper, the application of a two-phase flow model to scour processes is presented. The model is first calibrated against experimental data of unidirectional sheet-flow (one-dimensional configuration). The model is then applied to multi-dimensional configurations for the scour under a submarine pipeline and around a vertical pile. The results show that quantitative results can be obtained at the upstream sides of structures, the lee-wake erosion driven by the vortex shedding deserves further research.
