Acoustically induced stress analysis of center fuselage skin panels of a basic training aircraft using statistical energy analysis
Kurtoğlu, İlker; Çalışkan, Mehmet; Department of Mechanical Engineering (2009)
Two sample statistical energy analysis (SEA) models are generated for a section of the fuselage panel of an aircraft, namely the uniform panel model which includes the frames and stringers, and the ribbed panel model in which the frames and stringers are smeared into the skin. Turbulent boundary layer (TBL) excitation is used as the primary acoustic excitation source. Stress levels are estimated from the average velocity data of the panels. The stress results are found comply with those obtained by the AGAR...
Prediction of the transient force subsequent to a liquid mass impact on an elbow of an initially voided line
Kayhan, Bülent Abbas; Bozkuş, Zafer; Department of Civil Engineering (2009)
The aim of the thesis, is to find the transient force applied by an individual transient liquid slug on an elbow at the end of a horizontal line due to an impact. The liquid slug is driven by pressurized air in a tank located upstream of the pipeline. The time dependent pressure distribution along the elbow and a vertical extension segment after the elbow was solved, with a 1-D numerical approach along a curved line mesh. For this purpose; firstly, a 3-D axial turbulent velocity profile function was assumed...
Exploration of instructional design process and experience of novice instructional designers through the framework of activity theory : a case study in an instructional design course
Karakuş, Türkan; Çağıltay, Kürşat; Department of Computer Education and Instructional Technology (2011)
Contextual issues have considerable role on learning outcomes of instructional design process. In this dissertation study, an instructional multimedia design and development course was explored to understand how contextual issues influence the experience and processes of Novice Instructional Designers’ (NIDs) activities in an instructional design project. The main participants of the study were 47 junior Computer Education and Instructional Technology students who were enrolled in the course. Besides, 26 st...
Perceptions on the use of printed vs. interactive electronic technical manual in a training: a basic qualitative research
Böğürcü, Ceylin; Delialioğlu, Ömer; Department of Computer Education and Instructional Technology (2019)
The main purpose of this study was to understand the perceptions of participants of a technical training on utilization of interactive electronic form materials prepared with IETM technology. Specifically the study aims to examine their opinions, comments and evaluations about their experiences and have them compare printed materials with the mobile digital content. The participants of the study were 8 employees who volunteered to contribute to the study out of 25 employees in Integrated Logistics Support d...
Design of a compliant bistable loock mechanism for a dishwasher functionally binary initially curved pinned-pinned segments
Ünverdi, Uygar; Söylemez, Eres; Department of Mechanical Engineering (2012)
The aim of this study is to design a compliant lock mechanism for a dishwasher, using a systematic approach. Functionally binary pinned-pinned segment that exhibits bistable behavior is utilized. Pseudo-rigid-body model of the whole mechanism and the half segment is developed separately and the corresponding calculations are carried out. Among current solutions a different method namely “arc fitting method” is developed and it is utilized to construct the model. A software code is written to get the exact s...
