In this paper a support vector machine based handwritten numerals recognition system of Manipuri Script (Meetei Mayek) is investigated. We have used various feature extraction technique such as background directional distribution (BDD), zone based diagonal, projection histograms and Histogram Oriented Gradient features. In Background Directional Distribution (BDD) features background distributi...

Abstract The increasing demands of highly precise industrial products lead to continuous seeking for the improvements in cabapility manufacturing machines, i.e., machine tools. Machine tools include different types turning, lathe, drilling, and milling machines whatever computerized numerical control (CNC) type or manual type. cabaplity improvement requires a real understanding their productivi...

Shale gas represents a major fraction of the proven reserves of natural gas in the United States and a collection of other countries. Higher gas prices and the need for cleaner fuels provides motivation for commercializing shale gas deposits even though the cost is substantially higher than traditional gas deposits. Recent advances in horizontal drilling and multistage hydraulic fracturing, whi...

BACKGROUND Most studies examining the safety and efficacy of transphyseal anterior cruciate ligament (ACL) reconstruction for skeletally immature patients utilize transtibial drilling. Independent femoral tunnel drilling may impart a different pattern of distal femoral physeal involvement. PURPOSE To radiographically assess differences in distal femoral physeal disruption between transtibial ...

Global demand growth has driven the development of more inventive methods for enhancing oil well drilling at lower prices and avoiding operational issues that slow down drilling. The present research is significant because lifting capacity may be increased by inserting polymer beads into mud instead high-cost additives. numerical cuttings trajectory simulation was performed using commercial ANS...

US Army Research Laboratory researchers designed a head-up display (HUD) that overlays driving information on a switchable vision block. Bradley and Stryker drivers were surveyed for recommendations to incorporate in the prototype. A simulation experiment was conducted to evaluate a HUD versus a traditional head-down display (HDD). Results about driving task performance were mixed, with the HUD...

the use of multilateral well is becoming an emerging method to improve oil recovery efficiently and to drain reservoirs more efficacious. by developing drilling technology, completing the oil wells as multilateral wells become more interesting especially from economic point of view. on the other hand, lack of any means for forecasting the performance of this type of wells causes drilling of the...

a r t i c l e i n f o The use of high-volume horizontal hydraulic fracturing (fracking) has increased substantially over the past five years in the United States. Use of this drilling technology to extract natural gas from hitherto impermeable shale is expected to increase even more in coming decades. Two institutions, integration contracts and well spacing requirements, evolved to mitigate the...

Aims: To discover the predictors of change in the frequency of heavy drinking (HD) over a 4-year period in alcohol dependent (AD)-individuals identified in the general population, namely, among participants of the US National Epidemiologic Survey on Alcohol and Related Conditions interviewed at Wave 1 (2001–2002) and at Wave 2 (2004–2005). Methods: The study cohort included subjects meeting DSM...
