Student Learning and Retention Using a Flight Training Device: A Case Study

Student learning and retention as a function of the mode of teaching is analyzed in this study. Different groups of students receive information about aircraft flight operations either via lecture, through directed study, a combination of the two or through a pre-recorded flight demonstration video. Their level of learning is assessed by evaluating how well they fly an aircraft and perform a predefined mission using a flight simulator. Scores of different groups are compared qualitatively and quantitatively and students are surveyed after the flight. It is hypothesized that students that learn through watching a demonstration video and have the ability to review the demonstration multiple times perform better than all other groups. Additionally, students that have access to literature beforehand and receive a lecture prior to the flight perform better than those that only review the literature or only receive a lecture before the simulation. Also, the efficacy of the hands-on learning in a laboratory environment is discussed

Needs Assessment in ESP: A Review

Needs assessment of the learners in English language is considered as an important domain that comes under the ambit of ESP “English for Specific Purposes”. English cogitates as a lingua franca and a cornerstone for success in any field. However, in ESL/ELT it is imperative to design a course that caters for the needs of the learners. Thereby this study attempts to evaluate the existing needs assessment literature to corroborate its relevancy and adequacy in preparing the nursing professionals for their professional English language requirements. In this evaluative study, needs analysis and assessment literature have been reviewed. ESP is explored in various ways like its definitions, classification, development, different approaches to needs analysis

Blended Wing Body Propulsion System Design

This research paper focuses on the optimization of the propulsion system of a blended wing body design. Two different aspects of the design, the engine placement and count, and the engine itself, are investigated. The preliminary wing of the BWB is created through aerodynamic analysis, and is kept as a constant over the different propulsion system configurations. The engine parameters are first investigated. Equations are derived to express takeoff distance and climb rate as a function of engine sea level thrust, cruise thrust, and the number of engines. Nearly 150 different engine models, in BWB configurations of 2, 3, 4, and 8 engines, are analyzed from these equations. Engines that satisfy the constraints of less than 3000 meters takeoff run at sea level and climb rates comparable to those of a large modern airliner are then shortlisted, after which the engine with a proper balance of excess thrust and SFC is selected for each case. Six different BWB models are then created in CAD software. Mathematical computations are conducted on each of the models to find maximum takeoff weight, drag coefficient, empty weight, and more. A relative comparison of the lift to drag ratios of the models is also conducted in SolidWorks CFD. The results showed that the 8 engine aft BWB model had the highest lift to drag ratio, but had slightly higher empty weight than four of the designs and a lower maximum takeoff weight and specific fuel consumption than all others

Aerodynamic Optimization of Box Wing – A Case Study

The optimization of a possible medium range box wing commercial airliner is presented in three stages. Preliminary research is used to determine various parameters for a potential box wing model, and a baseline model is designed in Autodesk Inventor, based upon the cantilever Airbus A330-200, an aircraft of a similar role. The Computational Fluid Dynamics (CFD) software used in this project is Dassault Systèmes SolidWorks, which is validated through comparing the NACA 0009 airfoil lift and drag polars with published results. The first stage of optimization is performed on the airfoil shape, with 8 different designs being tested against the cantilever model. The lift to drag ratios of each model are calculated at cruise conditions, Mach 0.85 and 11,000 meters altitude. The most efficient model with the highest lift to drag ratio is then taken to the second stage of optimization, winglet height, where 7 different winglet heights are tested on the model: 5%, 10%, 15%, 20%, 25%, 30%, and 35% of the span. The most efficient model out of the different winglet heights is then tested with 7 different aspect ratios: 5%, 10%, 15%, 20%, 25%, 30%, and 35%. The expectation of the three stages of optimization is to provide a box wing model that performs significantly better than the original base line model, and also has an improved lift to drag ratio when compared to the cantilever model

THE RELATIONSHIP BETWEEN CORRUPTION AND ECONOMIC GROWTH IN PAKISTAN — LOOKING BEYOUND THE INCUMBENT

Corruption has opaque significant consideration for researchers during the last few decades due to its effect on economic growth. This study examines the relationship between corruption and economic growth in Pakistan, covering the period from 1985 to 2010. Stationarity of the variables was checked through unit root test and then apply multiple regression technique. The results shows that government expenditures, education expenditures and population growth has a positive impact on per capita GDP, however, domestic investment and corruption has a negative impact on per capita income in Pakistan. It implies that corruption is a major factor impeding economic development. Corruption hampers economic growth, disproportionately burdens the poor and undermines the effectiveness of investment and aid

Detect-and-describe: Joint learning framework for detection and description of objects

Traditional object detection answers two questions; “what” (what the object is?) and “where” (where the object is?). “what” part of the object detection can be fine grained further i-e. “what type”, “what shape” and “what material” etc. This results in shifting of object detection task to object description paradigm. Describing object provides additional detail that enables us to understand the characteristics and attributes of the object (“plastic boat” not just boat, “glass bottle” not just bottle). This additional information can implicitly be used to gain insight about unseen objects (e.g. unknown object is “metallic”, “has wheels”), which is not possible in traditional object detection. In this paper, we present a new approach to simultaneously detect objects and infer their attributes, we call it Detectand- Describe (DaD) framework. DaD is a deep learning-based approach that extends object detection to object attribute prediction as well. We train our model on aPascal train set and evaluate our approach on aPascal test set. We achieve 97.0% in Area Under the Receiver Operating Characteristic Curve (AUC) for object attributes prediction on aPascal test set. We also show qualitative results for object attribute prediction on unseen objects, which demonstrate the effectiveness of our approach for describing unknown objects

Effects of Perception of Organizational Politics on Employee’s Well-Being: The Mediating Role of Trust and Interpersonal Conflicts

Perception of organizational politics (POP) is a critical issue for all organizations. Most of the researchers indicate that it has a negative effect on employee’s performance. This study finds the relationship between POP and employee’s well-being (EWB) by using interpersonal conflicts at work (ICW) and interpersonal trust at work (ITW) as mediators. The well-being of employees is an important factor to be studied because it covers overall happiness of employees which includes job satisfaction, performance, job loyalty etc. Therefore, without concerning the employee’s well-being, no organization can compete or lead in the competitive environment. So there is a research gap which needs to conduct a research study on employee’s well-being with the reference to perception of organizational politics. The main focus of this study is to find out the relationship between employee’s well-being and perception of organizational politics with the mediating effect of interpersonal conflicts at work and interpersonal trust at work. The sample size of this study is in a number of 223 with cross-sectional study and conducted in the famous city Lahore, Pakistan

In vitro Anti-ulcer potential of Raphanus sativus L. seeds

Background: Raphanus sativus L. is an indigenous plant that is traditionally used to treat peptic ulcer. Objective: This study assessed anti- Helicobacter pylori, antioxidant, and anti-urease activities of R. sativus seeds. Methods: this study targeted in-vitro model. The antioxidant activity of the methanol extract and n-butanol, aqueous, n- hexane and chloroform fractions of R. sativus seeds was determined using DPPH. Moreover, the inhibitory effects of the extract and fractions on the activity of urease and antibacterial activity against Helicobacter pylori were also evaluated. Results: The crude extract as well as its derived n-butanol fraction exhibited higher (IC50: 45 and 31 µg/mL respectively) DPPH inhibition activity and inhibition of urease (IC50: 75.0 and 55.9 µg/mL respectively) while aqueous extract inhibited H. pylori strongly (MIC50: 15 µg/mL). Conclusion: Collectively, our data show that R. sativus extract and fractions possess antioxidant, anti- H. pylori and anti-urease potential. The traditional uses of R. sativus as anti-ulcer, might be due to its anti-urease activity
