We consider the method of designed experiments for statistical tolerance analysis, and study the impact of experimental error on its results.-It is observed that presence of random error in the experiment environment (e.g. laboratory) could introduce bias in the moment estimators and increases their-respective variances. We propose adjustments to the method that would reduce the bias as well as the variance of these estimators. A numerical example is presented.

Numerical and experimental investigation of damping in a dam-break problem with fluid-structure interaction Demir, Abdullah; Dincer, Ali Ersin; Bozkuş, Zafer; Tijsseling, Arris S. (Zhejiang University Press, 2019-04-01) There have been few experimental and numerical studies on damping effects in fluid-structure interaction (FSI) problems. Therefore, a comprehensive experimental study was conducted to investigate such effects. In experiments, a water column in a container was released and hit a rubber plate. It continued its motion until hitting a downstream wall where pressure transducers had been placed. The experiments were repeated using rubber plates with different thickness and material properties. Free-surface profil...
Quadrature error compensation and its effects on the performance of fully decoupled MEMS gyroscopes Tatar, Erdinç; Akın, Tayfun; Department of Electrical and Electronics Engineering (2010) This thesis, for the first time in the literature, presents the effect of quadrature error compensation on the performance of a fully decoupled MEMS gyroscope and provides experimental data on the sources of quadrature error. Dedicated quadrature error cancellation electrodes operating with only differential DC potentials are designed. Gyroscopes with intentionally placed imperfections are fabricated with SOG based SOI process which provides higher yield and uniformity compared to SOG process. Tests show th...
Conceptual change oriented instruction and students' misconceptions in gases Azizoğlu, Nursen; Geban, Ömer; Department of Secondary Science and Mathematics Education (2004) The purpose of this study was to investigate the effects of conceptual change oriented instruction accompanied by demonstrations and gender on tenth grade students̕ understanding of gases concepts, and attitudes toward chemistry. Hundred tenth grade students from two classes taught by the same teacher in a public high school were enrolled in the study in the Fall semester of 2003-2004. Control group students were taught by traditionally designed chemistry instruction (TI), while experimental group students ...
A unifying grid approach for solving potential flows applicable to structured and unstructured grid configurations Cete, A. Ruhsen; Yuekselen, M. Adil; Kaynak, Uenver (Elsevier BV, 2008-01-01) In this study, an efficient numerical method is proposed for unifying the structured and unstructured grid approaches for solving the potential flows. The new method, named as the "alternating cell directions implicit - ACDI", solves for the structured and unstructured grid configurations equally well. The new method in effect applies a line implicit method similar to the Line Gauss Seidel scheme for complex unstructured grids including mixed type quadrilateral and triangle cells. To this end, designated al...
Experimental modal analysis of a steel grid frame Kaya, Hüseyin; Türer, Ahmet; Department of Civil Engineering (2004) In this study, experimental modal analysis was studied. Experimental modal analysis includes modal testing, modal parameter estimation and calibration. For this purpose a 4 span skewed steel frame was constructed in Structural Mechanics Laboratory of Civil Engineering Department of METU. The model was transported to Vibration and Acoustic Laboratory of Mechanical Engineering Department of METU. The tests were conducted by cooperation with Vibration and Acoustics Laboratory. Due to lack of experimental modal...
