Multiphase Flows In Vertical Pipelines
The modeling of fluid dynamics through pipelines requires a full understanding of the internal and external factors that influence its transients. The Navier-Stokes momentum equation represents a complete description of the forces acting on a fluid. The equation’s non-linear terms enable to take …

Learning efficient image processing pipelines
… performance pressure on image processing pipelines. Tuning the parameters of these pipelines for speed is subject to stringent image quality constraints and requires significant efforts from skilled programmers. Because quality is driven by perceptual factors with which most quantitative …

Converting PyTorch Models to StreamIt Pipelines
… the dynamic computation graph of PyTorch to pipelines in StreamIt, a domain specific language (DSL) for streaming applications, and use the multi-stage compilation property of BuildIt to compile this pipeline in stages to inference code. We found that, while the inference latencies of models …

Synthesis Of Self-resetting Stage Logic Pipelines
… and used to propose three types of clockless pipelines. Experimental studies show that these pipelines have the potential to produce high throughputs with a minimum area overhead if a suitable synthesis methodology is available. This thesis proposes a novel synthesis methodology to design and …

Estimation of Wax Deposition in Subsea Pipelines
… wax deposition rate within subsea production pipelines. This research employs experiments from 1-D and 2-D multiphase flow that have been successfully matched by a combined physics model on a closed-loop structure where the measuring length was 2.5m and the pipe inside diameter 0.0144m. The …

Pressure-based leakage characterisation of bulk pipelines
… is leakage on bulk pipeline systems. Bulk pipelines connect water treatment plants to bulk reservoirs and distribute water from reservoirs to different towns or water supply zones. Bulk pipes may be operated using pumps or gravity, and generally do not supply consumers directly. It is …

Wave forces on submarine pipelines : a review
In Part I theoretical aspects of hydrodynamic forces on immersed solids are considered. Part II contains a chronological review of research projects, laboratory as well as ocean experiments, which have been carried out since 1950. In Part III the recommended procedures, which emerge from Part. II, …

Seismic analysis of pipelines with yielding supports
Pipelines in structures such as a nuclear reactor can be analysed separately when the structure is subjected to seismic type loading. The pipeline is modelled with various types of supports, such as a rigid support or an elastic support. The pipeline is analysed and designed so that stresses in the …

Uncertainty Quantification in Security Aware Data Pipelines
… information collected and processed through data pipelines is crucial. Traditional data pipelines usually perform error analysis of the final pipeline output after a detection model. As a result, they miss malicious attacks or data corruption that occur earlier in the pipeline. Providing assurance …

Optimizing analysis pipelines for improved variant discovery
… As such, the development of reliable sequencing pipelines is hugely important as a foundation for any future analysis on that data. While much existing work has been done on enhancing the throughput and computational performance of such pipelines, there is still the question of accuracy. The rift …

Behaviour of buried pipelines subjected to external loading.
The research presented in this Thesis was carried out at the University of Sheffield under the supervision of Dr I. C. Pyrah and Dr W. F. Anderson, and Mr G. Leach at British Gas Engineering Research Station (ERS). The research was financially supported by a British Gas Research Scholarship and by …

Prediction of pressure losses in pneumatic conveying pipelines
… the pressure drop along pneumatic conveying pipelines in process plant could be predicted. The methods previously available for making this prediction are examined and critically assessed. The need for a different method is shown, and a new approach is developed and tested. The new approach …

Reliability analysis and service life prediction of pipelines
Pipelines are extensively used engineering structures for conveying of fluid from one place to another. Most of the time, pipelines are placed underground, surcharged by soil weight and traffic loads. Corrosion of pipe material is the most common form of pipeline deterioration and should be …
