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 solutions, which require the evaluation of elliptic integrals. Results are compared with the analytical model and confirmed with physical prototype. Predefined tip forces are seen to provide the transition from one stable position to other. Durability, reliability and compactness characteristics are particularly considered.

Assessment of optimum threshold and particle shape parameter for the image analysis of aggregate size distribution of concrete sections Ozen, Murat; Güler, Murat (Elsevier BV, 2014-02-01) Aggregate gradation is one of the key design parameters affecting the workability and strength properties of concrete mixtures. Estimating aggregate gradation from hardened concrete samples can offer valuable insights into the quality of mixtures in terms of the degree of segregation and the amount of deviation from the specified gradation limits. In this study, a methodology is introduced to determine the particle size distribution of aggregates from 2D cross sectional images of concrete samples. The sampl...
Selection and utilization of criteria for process development in green production of organic chemicals Haydaroğlu, Şencan; Gürkan, Türker; Department of Chemical Engineering (2008) Sustainability and green engineering are two main concepts considered throughout this study. Sustainability deals with the utilization of renewable and replaceable sugar-based twelve most promising building blocks included in the report prepared by U.S. Department of Energy and green engineering concept is related with the incorporation of environmental performance criteria to chemical process design. Process performance criteria at the conceptual design stage are selected as persistence, bioaccumulation an...
Generation of patterned indentations for additive manufacturing technologies Yaman, Ulaş; Dölen, Melik; Hoffmann, Christoph (Informa UK Limited, 2019-02-01) This article proposes a novel approach to generate patterned indentations for different additive manufacturing methodologies. Surface textures have many practical applications in various fields, but require special manufacturing considerations. In addition to conventional manufacturing processes, additive processes have also been utilized in the last decade to obtain textured surfaces. The current design and fabrication pipeline of additive manufacturing operations have many disadvantages in that respect. F...
A Methodology for Optimal Layout Design of Pressure Cells for Concrete Faced Rockfill Dams Arı, Onur; Yanmaz, Ali Melih (Springer Science and Business Media LLC, 2018-08-01) In this study, a methodology for optimal layout design of pressure cells for concrete faced rockfill dams is developed. A representative dimensionless stress distribution model was formed for obtaining the magnitudes and location of different stress zones as a function of dam height. This information enabled development of a procedure for proper location and the number of pressure cells throughout the dam body. A vertical placement algorithm based on error minimization was first developed, which is followed...
Determination of optimal product styles by ordinal logistic regression versus conjoint analysis for kitchen faucets Demirtas, Ezgi Aktar; ANAGÜN, AHMET SERMET; Köksal, Gülser (Elsevier BV, 2009-09-01) In this study, a two-stage integrated approach is proposed and implemented to explore user perceptions about kitchen faucet styles and to find optimal levels of design parameters related to product appearance. At the first stage, a group of representative users have been asked to judge 38 systematically selected different faucet designs by using a semantic differential (SD) scale for 11 image (kansei) words about their visual perceptions. Then the relations between overall preference and kansei word scores ...
