    Purpose: The purpose of this research is to show significant points which can be used in the architectural design process by investigating the basic principles of earthquake resistant design (ERD) in a deductive format and to contribute to the architectural perception in ERD. Design/methodology/approach: First, the structural irregularity types are examined depending on the rules defined in the Turkish Earthquake Code, 2007 (TEC). Then, architectural design failures related to earthquake resistance of buildings under earthquake loading are visualized and solution suggestions in literature are described in detail by supported drawings. Findings: The problems causing structural irregularities are investigated deeply with given solutions in literature. It is obtained that the significant factors affecting the earthquake performance of structures are: architectural form, structural configuration, slenderness ratio, the location and rate of floor openings, projection rates and symmetry, rigidity and strength differences between floors, short columns, pounding effect. Social implications - The practical design decision rules can contribute to the phenomena of earthquake resistant architectural design and can encourage adoption of these rules in building industry. Originality/value: This study aims to gain an understanding of the problems in projects in terms of structural irregularities, and then manage to solve the problems using problem-oriented approaches. The suggested solutions can be adopted and applied to future projects for designing earthquake resistant buildings

    We show that two of the nonlinear lattice equations studied by Ayhan & Bekir [Commun Nonlinear Sci Numer Simulat 17 (2012) 3490-3498] have already been investigated by Aslan [Commun Nonlinear Sci Numer Simulat 15 (2010) 1967-1973] using an improved version of the same method. The solutions obtained by the latter one include the solutions obtained by the former one. © 2012 Elsevier B.V

    Search diversification techniques for grammatical inference

    Grammatical Inference (GI) addresses the problem of learning a grammar G, from a finite set of strings generated by G. By using GI techniques we want to be able to learn relations between syntactically structured sequences. This process of inferring the target grammar G can easily be posed as a search problem through a lattice of possible solutions. The vast majority of research being carried out in this area focuses on non-monotonic searches, i.e. use the same heuristic function to perform a depth first search into the lattice until a hypothesis is chosen. EDSM and S-EDSM are prime examples of this technique. In this paper we discuss the introduction of diversification into our search space [5]. By introducing diversification through pairwise incompatible merges, we traverse multiple disjoint paths in the search lattice and obtain better results for the inference process.peer-reviewe
