Dependency parsing is a way of syntactic parsing and a natural language that automatically analyzes the dependency structure of sentences, and the input for each sentence creates a dependency graph. Part-Of-Speech (POS) tagging is a prerequisite for dependency parsing. Generally, dependency parsers do the POS tagging task along with dependency parsing in a pipeline mode. Unfortunately, in pipel...

This paper presents experimental results for a parallel pipeline STAP system with I/O task implementation using the parallel file systems on the Intel Paragon and the IBM SP. In our previous work, a parallel pipeline model was designed for radar signal processing applications on parallel computers. Based on this model, we implemented a real STAP application which demonstrated the performance sc...

The performance of the pipelining technique is highly dependent on the data dependency between instructions. In this paper, a pipeline scheduling algorithm, called hazards minimization with rotation scheduling (HAMMRS), is proposed to reduce pipeline hazards imposed by the data dependencies of the instructions in a loop. The HAMMRS algorithm is based on an architecture sensitive graph model, pi...

When fluid flow in a pipeline is suddenly halted, a pressure surge or wave is created within the pipeline. This phenomenon, called water hammer, can cause major damage to pipelines, including pipeline ruptures. In this paper, we model the problem of mitigating water hammer during valve closure by an optimal boundary control problem involving a nonlinear hyperbolic PDE system that describes the ...

A novel automation pipeline for macromolecular structure solution by molecular replacement is described. There is a special emphasis on the discovery and preparation of a large number of search models, all of which can be passed to the core molecular-replacement programs. For routine molecular-replacement problems, the pipeline automates what a crystallographer might do and its value is simply ...

Pipeline transportation is the key component of mine filling system. In this study, fresh cement tailing backfill (CTB) slurry made by unclassified tailings from Daye iron taken as research object, and its rheological parameters transport characteristics are studied via laboratory test FLUENT software. It was found that relationship curve dynamic yield stress, viscosity, solid content (SC) CTB ...

This paper describes the design of an interpolated pipeline analog-to-digital converter (ADC). By introducing the interpolation technique into the conventional pipeline topology, it becomes possible to realize a more than 10-bits resolution and several hundred MS/s ADC using low-gain open-loop amplifiers without any multiplying digital-to-analog converter (MDAC) calibration. In this paper, line...

Pipeline transportation can benefit from a large suite of automation techniques, which can help to monitoring, controlling or optimizing the process. This paper deals with the modeling of the fluid flow in pipelines and presents the results obtained from the model. The software application developed from the model allows designing a pipeline system, computing the properties of a fluid in any po...

A distributed parameter model of pipeline transmission line behaviour is presented, based on a Galerkin method incorporating frequency-dependent friction. This is readily interfaced to an existing model of the pumping dynamics of a plunger pump to allow time-domain simulations of pipeline pressure pulsations in both suction and delivery lines. A new model for the pump inlet manifold is also pro...
