In surface fitting problems, the selection of knots in order to get an optimized surface for a shape design is well-known. For large data, this problem needs to be dealt with optimization algorithms avoiding possible local optima and at the same time getting to the desired solution in an iterative fashion. Many computational intelligence optimization techniques like evolutionary optimization algorithms, artificial neural networks and fuzzy logic have already been successfully applied to the problem. This paper presents an application of another computational intelligence technique known as "Artificial Immune Systems (AIS)" to the surface fitting problem based on B-Splines. Our method can determine appropriate number and locations of knots automatically and simultaneously. Numerical examples are given to show the effectiveness of our method. Additionally, a comparison between the proposed method and genetic algorithm is presented.

A New Design Approach for Rapid Evaluation of Structural Modifications Using Neural Networks Demirkan, O.; Olceroglu, E.; BAŞDOĞAN, FATMA İPEK; Özgüven, Hasan Nevzat (2013-02-01) Design optimization of structural systems is often iterative, time consuming and is limited by the knowledge of the designer. For that reason, a rapid design optimization scheme is desirable to avoid such problems. This paper presents and integrates two design methodologies for efficient conceptual design of structural systems involving computationally intensive analysis. The first design methodology used in this paper is structural modification technique (SMT). The SMT utilizes the frequency response funct...
A Low Complexity Two-Stage Target Detection Scheme for Resource Limited Radar Systems Candan, Çağatay (2013-01-01) A two-stage detector is proposed to accommodate high computational load requirements of modern radar systems. The first stage of the proposed system is a low-complexity detector that operates at an unusually high false alarm probability value around 1/10. This stage is to prescreen and eliminate some of the test cells with relatively few operations. The second stage operates only on the cells passing the prescreening stage and implements a high-complexity detector at a desired system false alarm rate. Due t...
An Approach for the Evaluation of Effective Elastic Properties of Honeycomb Cores by Finite Element Analysis of Sandwich Panels Aydincak, Ilke; Kayran, Altan (SAGE Publications, 2009-09-01) Different detailed finite element model alternatives are developed to come up with the most reliable finite element model of the sandwich panel, with the actual honeycomb core geometry, to evaluate the existing equivalent continuum models of aluminum honeycomb cores. Finite element models of sandwich panels with effective elastic constants of the honeycomb core are generated based on the existing continuum models of the honeycomb core. The evaluation of the effective elastic constants of honeycomb cores is ...
INVESTIGATION OF DAMAGE IN GFRP TAPERED COMPOSITE LAMINATES Hosseinpour Dashatan, Saeid; Arıkan, Mehmet Ali Sahir; Parnas, Kemal Levend; Department of Mechanical Engineering (2021-8-13) In some applications of composite laminates, thickness variation is necessary to fulfill specific design requirements. One way of accomplishing the intentional thickness variation in composite structures is terminating some plies within a layup. Introducing ply drop-offs causes geometrical and material discontinuities, which lead to high localized stresses around drop-off locations. Despite all the progress made in damage analyses of tapered composite laminates, estimating their load-carrying capacity and s...
A new formulation for the analysis of elastic layers bonded to rigid surfaces Pinarbasi, Seval; Akyüz, Uğurhan; Mengi, Yalcin (Elsevier BV, 2006-07-01) Elastic layers bonded to rigid surfaces have widely been used in many engineering applications. It is commonly accepted that while the bonded surfaces slightly influence the shear behavior of the layer, they can cause drastic changes on its compressive and bending behavior. Most of the earlier studies on this subject have been based on assumed displacement fields with assumed stress distributions, which usually lead to "average" solutions. These assumptions have somehow hindered the comprehensive study of s...
