Taschenbuch. Condizione: Neu. Neuware - Academic Paper from the year 2021 in the subject Education - Educational Tests & Measurements, , language: English, abstract: The purpose of this study was to examine the special education programs used in inclusive schools in Ethiopia from the perspective of teachers. The study also aimed to determine whether statistically significant differences were in teachers' perceptions of their status, gender, teaching experience, and level of education. 615 question papers with 20 Likert statements are distributed to a random sample of general and special education teachers working in areas including Ethiopia. Eighty-five percent (n = 523) teachers completed and returned practical questions. Analysis of the data collected, using descriptive statistics and variance analyzes, has shown that teacher assessments of special educational programs used in their schools are generally acceptable. The results also show significant differences in the assessment of teachers in terms of their position and level of education.…

Taschenbuch. Condizione: Neu. Neuware - Master's Thesis from the year 2020 in the subject Engineering - Automotive Engineering, Jimma University College of Agriculture and Veterinary Medicine, language: English, abstract: To improve the road handling and passenger comfort of a vehicle, a suspension system is provided. An active suspension system is considered to be better than the passive suspension system. In this thesis, 2 degrees of freedom of a linear quarter car active suspension system is designed, which is subject to different disturbances on the road. Since the parametric uncertainty in the spring, the shock absorber, mass and the actuator has been considered, robust control is used. In this thesis, H and µ- synthesis controllers are used to improve the driving comfort and the ability to drive the car on the road. For the analysis of the time domain, using a MATLAB script program and performed a test using four disturbance inputs of the road (bump, random, sinusoidal and harmonic) for the suspension deflection, the acceleration of the body and the body travel for the active suspension with the H controller and active suspension with µ- synthesis controller and the comparative simulation and reference results demonstrate the effectiveness of the presented active suspension system with µ- synthesis controller.In addition, in this thesis, comparison have been made between the active suspension system with µ-synthesis controller and 5 different robust controller for suspension deflection, body acceleration and body travel tests using bump, random, sinusoidal pavements and harmonic road disturbances. Body accelerations comparison of the active suspension system with µ-synthesis controller with VW (Volkswagen) Passat B5 passenger car is done for a bump road input disturbance and the result shows that there is a 50% reduction in body acceleration for the active suspension system with µ- synthesis controller.…

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Akademische Arbeit aus dem Jahr 2021 im Fachbereich Pädagogik - Bewertungsmethoden, Noten, , Sprache: Deutsch, Abstract: Since no clear pedagogical strategy was adopted in online instruction and since there was no accurate screening for the practices of teachers and learners, this study reflects the quality of online instruction from students' perspectives. Therefore, this paper holistically describes online learning as it was experienced by Grade 9 and Third Secondary learners in Ethiopia. A quantitative study was conducted through an online survey and the data was collected from 928 respondents. The limitations of the study are the small sample size as well as the absence of teachers' views.…
