Article A Parametric Study on the Elastic-Plastic Deformation of a Centrally Heated Two-Layered Composite Cylinder With Free Ends(Polish Acad Sciences inst Fundamental Technological Research, 2016) Yalcin, F.; Gülgeç, Müfit; Ozturk, A.; Gulgec, M.; Mekatronik MühendisliğiIn this paper, an elastic-plastic deformation of a centrally heated two-layered composite cylinder with free ends subjected to uniformly distributed internal energy generation within an inner cylinder is studied using Tresca's yield condition and its associated flow rule. Stress, strain and displacement distributions in the composite cylinder made of elastic-perfectly plastic material are derived considering the influence of geometric parameters as well as material properties such as yield strength, modulus of elasticity, Poisson's ratio, coefficient of thermal conduction and coefficient of thermal expansion. Yielding starts at the outer boundary or at the axis corresponding to an 'edge regime' of Tresca's prism in both cases. Propagations of the plastic regions are studied due to an increase of a heat generation.Conference Object Citation - Scopus: 1Lensfree On-Chip Fluorescence Microscopy for High-Throughput Imaging of Bio-Chips(2014) Coskun, A.F.; Arpali, S.A.; Arpali, C.; Su, T.-W.; Sencan, I.; Herman, D.; Ozcan, A.On-chip fluorescence microscopy is an emerging platform that enables high-throughput screening of bio-chips over a wide field-of-view without the use of any lenses, thin-film filters or mechanical scanners. In this review, we summarize the recent advances in lensfree fluorescence microscopy and also discuss some of its unique capabilities toward high-throughput screening applications, including rare-cell imaging, on-chip cytometry and as well as micro-array research. © 2014 Springer Science+Business Media.Article Citation - WoS: 2Citation - Scopus: 6Controller Area Network With Priority Queues and Fifo Queues: Improved Schedulability Analysis and Message Set Extension(inderscience Enterprises Ltd, 2016) Schmidt, Klaus Werner; Alkan, Burak; Schmidt, Ece Guran; Karani, Duygu Culum; Karakaya, UtkuController area network (CAN) enables communication of electronic control units (ECUs) via messages using priority-based arbitration, which requires the implementation of priority queues (PQs) in the ECU device driver. Nevertheless, it is possible that not all ECUs on a CAN support PQs but use FIFO queues (FQs) instead. In this case, the classical CAN scheduling model with PQs is not suitable for the computation of message worst-case responsetimes (WCRTs) that are essential for verifying the correct vehicle operation. This paper considers an existing scheduling model for CAN with both PQs and FQs. First, an improved algorithm for speeding up the WCRT computation is proposed. Second, the practical case where an existing CAN message set is extended by new messages is addressed. An original algorithm for assigning priorities to new messages while keeping the priority order of existing messages is developed. Both algorithms are evaluated by computational experiments.
