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 purpose of the software development presented in article is to obtain detailed information about surface walls wells necessary for more efficient and safe drilling casing wellbore. developed automated system “LogPWin” allows obtaining a clear idea mine itself, as well reducing time spent on processing analyzing model obtained during logging process. A product result work provides visualizat...

objective and aims intrauterine devices (iuds) are placed in the uterine cavity with the objective of providing long-term contraception, mainly by preventing fertilization. in this research has been tried to show that method of iud insertion is effective to decrease complications’ incidence . rotating withdrawal technique is presenting, has been using for this purpose. design and setting this h...

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...

A large amount of casing deformation has occurred in shale gas wells during the complex fracturing process, which affects construction and single well production. Based on statistical analysis caliper logging interpretation, main mechanism is revealed as formation slip. By comprehensively considering rotating speed under running condition, cement solidification heat release cementing fluid temp...

Unsteady numerical simulation of single passage was carried out on NASA Rotor 35 to study the influence radial inclined angle self-circulation casing treatment (SCT) performance and stability a transonic compressor at 100% design speed. The angles were set 0°(D0), °(D30) 60°(D60), respectively. calculated result indicates an increase in stall margin improvement (SMI) efficiency (DEI) as increas...

Blade tip-timing is one of the most widely used non-contact measurement methods for rotating blade vibration. The classic method to identify vibration parameters based on time tip arrival sensor installed casing. Since a serious under-sampling method, resonance frequency usually higher than sampling BTT data acquisition system, resulting in large identification error parameters. In view above s...
