Steam turbines consist essentially of a casing to which stationary blades are fixed on the inside and a rotor carrying moving blades on the periphery. The rotor is fitted inside the casing with the rows of moving blades penetrating between the rows of fixed blades. Thus steam flowing through the turbine passes alternately through fixed and moving blades with the fixed blades directing the steam...

This paper describes the winning entry to the ALTA Shared Task 2013. The theme of the shared task was recovery of casing and punctuation information from degraded English text. We tackle the task as a sequential labeling problem, jointly learning the casing and punctuation labels. We implement our sequential classifier using conditional random fields, trained using linguistic features extracted...

The detection and the measuring of developing damages must be accompanied by evaluation supporting ability design in terms increasing size a defect. If type damage is dominant one on further period operation, so received functional dependences can used to predict residual life designs. As illustrated casing pipes 168.3 mm diameter, where general corrosion inner surface, algorithm receive expres...

During the development of oilfields, casings in long-term service tend to be damaged different degrees, leading poor ineffective water circulation, and wasted resources. In this paper, we propose a data-based method for predicting casing failure risk at both well well-layer granularity illustrate application GX Block an eastern oilfield China. We first quantify main control factors damage by ad...

Pipet tip loading of polymerase chain reaction (PCR) and other amplification products into an electrophoresis gel represents a potential source of laboratory contamination. We have developed a prototype of the gel contamination control system (GelCCS) that enables gel loading by bottom puncture of PCR tubes. Puncture occurs within a sealed gel casing, preventing contamination of the surrounding...

Carbon capture and storage is considered as an amelioration technique to address the increasing level of carbon dioxide in atmosphere. Depleted oil gas reservoirs are potential candidates for long sequestration captured dioxide. The huge number drilled wells these hydrocarbon around world, however, pose a threat integrity geological CO2 projects. These direct connections Earth’s surface even wh...

Abstract Multi-cluster fracturing technology was often used in horizontal well reservoir reconstruction to achieve production increase, which also affected casing equivalent stress distribution. This paper focuses on multi-cluster and establishes a model line with the reality. The three-dimensional finite element of fracture-formation-cement sheath-casing proposed, influence cluster spacing num...

These new computing environments will require a fundamentally new computing paradigm that will differ in both substance and scale from previous work on concurrent programming and distributed systems. Unlike current processors, processors in future systems will have direct links to the physical environment through distributed sensors and actuators. Using thousands of tiny computational elements ...
