Ocr: A Statistical Model Of Multi-engine Ocr Systems
… commercial Optical Character Recognition (OCR) engines. The purpose of this benchmark is to characterize the performance of the OCR engines with emphasis on the correlation of errors between each engine. The benchmarks are performed for the evaluation of the effect of a multi-OCR system …

Text-image Restoration And Text Alignment For Multi-engine Optical Character Recognition Systems
… different optical character recognition (OCR) engines (ExperVision® OCR, Scansoft OCR, and Abbyy® OCR) results using voting algorithms will get higher accuracy rate than each of the engines individually. While a voting algorithm has been realized, several aspects to automate and improve …

Range and endurance modelling of a multi-engine aircraft with one engine inoperative (oei)
When one of the engines on a multi-engine aircraft stops working the one engine inoperative (OEI) condition exists. This causes several negative effects to a number of performance variables in addition to the loss of engine thrust. The range and endurance of an aircraft are directly related to the …

Evaluating Scenarios That Can Startle and Surprise Pilots
… on the flight deck is a contributing factor in multiple aviation accidents that have been recognized by multiple aviation safety boards. This study identified the effects startle and surprise had on commercial pilots with single and multiengine ratings. Surprise is defined here as something …

Combining phrase-based and tree-to-tree translation
We present a novel approach to multi-engine machine translation, using a feature-based classification algorithm. Instead of just using language models, translation models, or internal confidence scores, we sought out other features that could be used to determine which of two translations to …

An Alternative Method of Identification of a Failed Engine in Twin-Engine Propeller Aircraft
… revealed that wrong identification of a failed engine during flight is not an uncommon event in an aircraft cockpit. A number of fatal accidents in the past, including the recent TransAsia Flight 235 accident, resulted from engine misidentification. Most accidents of this type happened on …

The Relationship of a Pilot's Educational Background, Aeronautical Experience and Recency of Experience to Performance in Initial Training at a Regional Airline
… include years since graduation from college, multi-engine time, total time and whether or not a pilot had military flying experience. Due to the pilot shortage, the pilots entering regional airline training classes since August 2013 have varied backgrounds, aeronautical experience and recency …

Extracting capacity metrics for General Aviation airports from ADS-B data
… that operate mainly with small single or multi-engine aircraft. These airports are typically not towered and, hence, do not benefit from traditional automated data collection technologies. This research addresses the issues of a) collecting aircraft data at local airport environments from …

Factors That Influence Pilot Usage of Flight Following
… Certificate, flying Weight-Shift Control or Multi-Engine aircraft, having ADS-B, TCAS, or a built in radio and purpose of flight.Using a qualitative method, this study also discovered categories or themes that emerged from pilot definitions of flight following and factors that influence pilot …

TransBooster:black box optimisation of machine translation systems
… as a promising alternative to current Multi-Engine MT techniques. We evaluate TransBooster on the language pair Engl~sh-+Spanish with a combination of automatic and manual evaluation metrics, prov~ding a rigorous analysis of the potential and shortcomings of our approach.

Simulation of rocket plume impingement and dust dispersal on the lunar surface
… a dusty surface, the plume from the descent engine impinges on the ground and entrains loose regolith into a high velocity spray. This problem exhibits a wide variety of complex phenomena such as highly under-expanded plume impingement, transition from continuum to free molecular flow, …
