A structural delay-insensitivity verification analysis method, SDIVA, is proposed for asynchronous systolic arrays in dual-rail threshold logic style. The SDIVA method employs symbolic delays for all output evaluation paths and works at the behavioral specification level. For bit-level pipelined systolic arrvys, which have data-dependent early output evaluation in one-dimension, SDIVA method reduces the verification analysis task to examination of three adjacent systoles so that by analyzing all possible early/late output evaluation scenarios on three systoles, the delay-insensitivity of a complete systolic array could be verified at once, regardless of the array dimensions. Delay-insensitivity violations are located and corrected at structural level, without diminishing the early output evaluation benefits. Since symbolic delays are used without imposing any timing assumptions on the environment; the SDIVA method is technology independent and robust against all physical and environmental variations.

Multiband Microwave Metamaterials Based on Optimized Arrangements of Split-Ring Resonators Ibili, H.; Keles, S.; Ergül, Özgür Salih (2019-01-01) We present design and accurate simulations of multiband metamaterials that consist of three-dimensional arrangements of split-ring resonators (SRRs). In order to obtain multiband characteristics with resonances at multiple frequencies, SRRs with different sizes are arranged in well-designed grids. As opposed to unit cells with nested SRRs that are commonly used in the literature, using different-sized SRRs in array forms provide better flexibility in choosing resonance frequencies. On the other hand, strong...
Performance analyses of newton method for multi-block structured grids Ayan, Erdem; Eyi, Sinan; Department of Aerospace Engineering (2011) In order to make use of Newton’s method for complex flow domains, an Euler multi-block Newton solver is developed. The generated Newton solver uses Analytical Jacobian derivation technique to construct the Jacobian matrices with different flux discretization schemes up to the second order face interpolations. Constructed sparse matrices are solved by parallel and series matrix solvers. In order to use structured grids for complex domains, multi-block grid construction is needed. Each block has its own Jacob...
Shape Optimizations of Metallic Sheets for Improved Near-Zone Scattering, Reflection, and Focusing Characteristics Altinoklu, Askin; Ergül, Özgür Salih (2017-10-12) We consider full-wave analysis and optimizations of metallic sheets to obtain desired electromagnetic responses in the near-zone field intensity and power density distributions. Given a metallic sheet of finite size, deformations are applied to achieve diverse scattering and reflection characteristics, particularly focusing and collecting electromagnetic power at different locations. Optimizations are performed by employing genetic algorithms in a multigrid scheme on the discretized geometry, while each tri...
Performance-based parametric design explorations: A method for generating appropriate building components Ercan, Burak; Elias Özkan, Soofia Tahira (2015-05-01) Performance-based parametric design explorations depend on formulating custom-designed workflows that require reading, writing, interpreting and manipulating databases, as part of the design process. The possibilities of customization and parameterization offered by the user-friendly interfaces of advanced building-performance simulation software and digital design tools have now enabled architects to carry out performance-based design explorations without the help of simulation experts. This paper presents...
Layout optimization of trusses using simulated annealing Hasançebi, Oğuzhan (2000-09-08) This paper addresses to the development of a simulated annealing (SA) based solution algorithm which is automated to achieve the simultaneous optimum design of truss type structures with respect to size, shape and topology design variables. The proposed algorithm is designed in such a way that together with applicability to practical design problems, it is also aimed at producing efficient and improved design solutions for the problems of interest. From the practicality point of view, the task is chosen as ...
