Computationally efficient shape analysis via level sets
Tarı, Zehra Sibel; Pien, Homer (null; 1996-01-01)
In recent years, curve evolution has been applied to smoothing of shapes and shape analysis with considerable success, especially in biomedical image analysis. The multiscale analysis provides information regarding parts of shapes, their axes or centers and shape skeletons. In this paper, we show that the level sets of an edge-strength function provide essentially the same shape analysis as provided by curve evolution. The new method has several advantages over the method of curve evolution. Since the gover...
Computationally enhanced techniques for practical optimum design of steel structures
Kazemzadeh Azad, Saeid; Hasançebi, Oğuzhan; Department of Civil Engineering (2014)
Practical optimum design of structural systems via modern metaheuristic algorithms suffers from enormously time-consuming structural analyses to locate a reasonable design. This study is an attempt to reduce the computational effort of optimization process involved in real-life applications through development of alternative techniques to the existing computationally expensive methods. Basically two main approaches are considered as (i) investigating the algorithmic structure of the existing metaheuristics ...
Computational Design and Analysis of Efficient Couplers for Nano-optical Links
Altinoklu, A.; Ergül, Özgür Salih (2019-01-01)
We present rigorous optimization and design of efficient couplers to improve optical transmission along nanowires. It is well-known that nanowires are excellent tools to transmit electromagnetic power in nano-optical systems, while couplers become inevitable at critical locations, particularly in input/output regions and at corners if nanowires are bended. We use genetic algorithms supported by fast full-wave solutions to efficiently and accurately obtain effective couplers in alternative scenarios. The des...
Computational analysis of network activity and spatial reach of sharp wave-ripples
Canakci, Sadullah; Toy, Muhammed Faruk; Inci, Ahmet Fatih; Liu, Xin; Kuzum, Duygu (Public Library of Science (PLoS), 2017-9-15)
Network oscillations of different frequencies, durations and amplitudes are hypothesized to coordinate information processing and transfer across brain areas. Among these oscillations, hippocampal sharp wave-ripple complexes (SPW-Rs) are one of the most prominent. SPW-Rs occurring in the hippocampus are suggested to play essential roles in memory consolidation as well as information transfer to the neocortex. To-date, most of the knowledge about SPW-Rs comes from experimental studies averaging responses fro...
Computationally efficient discrete sizing of steel frames via guided stochastic search heuristic
Azad, S. Kazemzadeh; Hasançebi, Oğuzhan (2015-08-01)
Recently a design-driven heuristic approach named guided stochastic search (GSS) technique has been developed by the authors as a computationally efficient method for discrete sizing optimization of steel trusses. In this study, an extension and reformulation of the GSS technique are proposed for its application to problems from discrete sizing optimization of steel frames. In the GSS, the well-known principle of virtual work as well as the information attained in the structural analysis and design stages a...
