The influence of weight on fuel consumption and range for a turboprop medium courier aircraft

Performance in the en route phase can be measured using the range and endurance parameters of the airplane. The range is a more useful performance parameter than endurance and one that aircraft designers are constantly trying to improve. While endurance refers to airborne time, the range is more concerned with distance covered and is therefore sometimes referred to as fuel mileage. In most cases, the trade-off between range and payload is achieved at the initial purchase of the aircraft and, subsequently during in-flight planning.

Prediction of Iranian EFL Teachers' Burnout Level Using Machine Learning Algorithms and Maslach Burnout Inventory

Burnout is that the end result of excessive work-associated pressure and it is categorized through emotional, psychological, and bodily exhaustion. we can remember it as a cutting-edge epidemic withinside the coaching career likewise as distinct professions. The measures that could have an impact on a lecturer and may reason burnout are categorized as Depersonalization, Emotional Exhaustion, Personal Accomplishment. alevin though articles on educator burnout range of their approach, they incline to specialize withinside the reasons of burnout, the manner to evaluate the symptoms and symptoms of burnout, strategies to forestall burnout, and/or subsequent steps for administrators and teachers. The principal problem that has been incomprehensible is the prediction of acquiring burned out. Through prediction, we can reduce lower back the fees of the burnout effect on teachers, students, schools, and society and forestall its results like depression, coronary failure, or possibly suicide. Our goal is to investigate and are expecting the burnout stage in English as a faraway Language (EFL) instructor. we're going to use Maslach Burnout Inventory (MBI) to collect a dataset and stay the three subscales of instructor burnout: emotional exhaustion, depersonalization, and decreased non-public accomplishment. whilst studying the amassed dataset that consisted of 1433 teachers' data, nine system getting to know type algorithms through enforcing exploitation python programing language is implemented and accuracy is hired as an overall performance parameter.

The Effect of Baffle Configuration on Heat Transfer and Pressure Drop Characteristics of Jet Impingement System with Cross-Flow

Use of baffles in jet impingement systems in presence of initial cross-flow disturbs boundary layer that results in rise in heat transfer. Two configurations of baffle assisted impingement systems were considered and a comparative study on heat transfer and pressure drop is carried out based on operating parameters such as baffle clearance, blow ratio and h/D ratio using commercially available CFD package. Numerical predictions showed that both heat transfer and pressure drop in segmented configuration were higher than louvered configuration for all blow ratio employed in this study. Parametric studies showed that, thermo-hydraulic performance parameter is higher only for louvered configurations at low blow ratio. When cross-flow velocity is comparable with jet velocity, segmented baffles resulted in relatively higher thermo-hydraulic performance because of its higher heat transfer rate relative to the incurring pressure drop. An increase in clearance proportionally increases performance parameter. However, as jet to plate distance increases, thermo hydraulic performance declines significantly.

Uncertainty in the Phase Flicker Measurement for the Liquid Crystal on Silicon Devices

Phase flicker has become an important performance parameter for the liquid crystal on silicon (LCOS) devices. Since the phase response of the LCOS device cannot be measured directly, it is usually derived from the intensity response of the modulated light beam when the LCOS device was placed between a pair of crossed polarisers. However, the relationship between the intensity of the beam and the phase response of the LCOS device is periodic. This would lead to uncertainty in the phase flicker measurement. This paper analyses this measurement uncertainty through both simulation and experiments. It also proposed a strategy to minimise the uncertainty.

Image Watermarking Approach Using a Hybrid Domain Based on Performance Parameter Analysis

In today’s scenario, image watermarking has been an integral part in various multimedia applications. Watermarking is the approach for adding additional information to the existing image to protect the data from modification and to provide data integrity. Frequency transform domain techniques are complex and costly and degrade the quality of the image due to less embedding of bits. The proposed work utilize the original DCT method with some modifications and applies this method on frequency bands of DWT. Furthermore, the output is used in combination with a pixel modification method for embedding and extraction. The proposed outcome is the improvement of performance achieved in terms of time, imperceptibility, and robustness.
