Ensuring proper punctuation and letter casing is a key pre-processing step towards applying complex natural language processing algorithms. This especially significant for textual sources where are missing, such as the raw output of automatic speech recognition systems. Additionally, short text messages micro-blogging platforms offer unreliable often wrong casing. survey offers an overview both...

The tightness of the casing-rock formation interface is one most important elements drilling and cementing jobs. In absence required tightness, there a risk gas migration directly to ground, groundwater or atmosphere. order eliminate this type uncontrollable unfavorable flows, casing column sealed with cement slurry in annular space beyond casing. Cement displaces mud present space, although ca...

Abstract This contribution focuses on the combined analysis of mistuning and unilateral blade-tip/casing contacts. A two-dimensional (2D) phenomenological finite element (FE) model an aircraft engine fan stage is considered. It reduced by means Craig–Bampton component mode synthesis method contact treatment relies a Lagrange multiplier algorithm within explicit time-integration scheme. Blade-ti...

Abstract Cement bond logs (CBL) and variable density log (VDL) are one of the vital logging techniques used to evaluate cement-casing-formation bonds before well testing or execution production operation in well. These also crucial during workover maintain integrity The provide a clear view quality cement with casing formation. microannulus other deviations bonding between formation recorded us...

In this work, the wellhead axial movement of a subsea well was predicted with previously presented multi-string model modified to account for possible buckling well’s surface casing. This represented structural casing nonlinear spring that considers casing-soil interaction using t-z curves hysteretic behavior. addition, modeled incorporates deformation when effective force is compressive and ma...

Calocybe indica is well known for its nutritional value, longer shelf life and ability to grow in warm humid climatic conditions. Casing material plays an important role cultivation yield determination. The present study explored the impact of different casing on biological efficiency (BE) indica. Here, we have used eight types sterilized thorough formalin, tunnel pasteurization autoclave metho...

To study the distribution law of circumferential residual stress after casing expansion, using finite element explicit dynamic analysis method analyzed expansion process expandable casings under different rates. The obtained key technical parameters stress, average and elastic recovery along wall thickness direction expansion. It is recognized that maximum tensile locates in middle part directi...

<p>Due to the thin and rigid wall of aeroengine casing, it is easy reduce machining accuracy due vibration machine tools cutting tools. Therefore, this paper designed an auxiliary fixture that can suppress such vibration.According absorption principle tuned mass damper, transfer energy casing so as itself.According Ansysworkbench analysis, significantly casing.The results show maximum amp...

Events and event structures compose the constituent elements of history. In order to construct historical accounts of event sequences, historians have to make cases. This article proposes a method for casing historical events. We illustrate the analytic strategy by considering a complex population of interrelated events that make up a narrative of revolution, counter revolution, and revolution ...
