BIM is a 3D model that contains both geometric and non-geometric information. This comprehensive data enables BIM to be used for many different purposes during various phases of the projects. However, the quality and completeness of the data generated during the design phase are essential for supporting all other uses of BIM. Therefore, it could be considered that the more effectively the design authoring process can be managed, the more favorable it will be for all BIM processes. Nowadays, BIM processes are described in technical specifications of metro projects, which have an important place in infrastructure investments. With the fact that BIM becoming compulsory in these projects, a need for adoption of new approaches for design collaboration arises. Therefore, in this study, a BIM-based design collaboration system is developed for metro projects that are tendered with the Design-Bid-Build delivery method in the Turkish AEC industry. The proposed system covers the main issues related to design collaboration, design automation, and information management. The automation and standardization of these processes constitute the main structure of the system. As a case study, the proposed system is used in a real metro design where design documents are generated for tendering purposes. The data obtained from the case study have been analyzed and compared with another metro project that was previously completed by the same firm, in terms of time, cost, the number of documents produced in the BIM environment, and file sharing process. In this context, the benefits and limitations of the proposed system are identified. According to the results of the study, there is an increase in the number of models generated and the number of documents produced from the models within a comparable amount of time. The study findings demonstrate the advantages of the proposed system and its potential for aiding fully benefit from BIM-based design for the firms in the Turkish AEC industry.

An advanced boundary element method (BEM) implementation for the forward problem of electromagnetic source imaging Akahn-Acar, Z; Gençer, Nevzat Güneri (IOP Publishing, 2004-11-07) The forward problem of electromagnetic source imaging has two components: a numerical model to solve the related integral equations and a model of the head geometry. This study is on the boundary element method (BEM) implementation for numerical solutions and realistic head modelling. The use of second-order (quadratic) isoparametric elements and the recursive integration technique increase the accuracy in the solutions. Two new formulations are developed for the calculation of the transfer matrices to obta...
A Comparative Study on Polygonal Mesh Simplification Algorithms Yirci, Murat; Ulusoy, İlkay (2009-01-01) Polygonal meshes are a common way of representing three dimensional surface models in many different areas of computer graphics and geometry processing. However, with the evolution of the technology, polygonal models are becoming more and more complex. As the complexity of the models increase, the visual approximation to the real world objects get better but there is a trade-off between the cost of processing these models and better visual approximation. In order to reduce this cost, the number of polygons ...
A Non-Structural Representation Scheme for Articulated Shapes Genctav, Asli; Tarı, Zehra Sibel (2018-10-01) Articulated shapes are successfully represented by structural representations which are organized in the form of graphs of shape components. We present an alternative representation scheme which is equally powerful but does not require explicit modeling or discovery of structural relations. The key element in our scheme is a novel multi scale pixel-based distinctness measure which implicitly quantifies how rare a particular pixel is in terms of its geometry with respect to all pixels of the shape. The spati...
Modeling of reaction-diffusion transport into a core-shell geometry King, Clarence C.; Brown, Amelia Ann; Sargın, Irmak; Bratlie, K. M.; Beckman, S. P. (2019-01-01) Fickian diffusion into a core-shell geometry is modeled. The interior core mimics pancreatic Langerhan islets and the exterior shell acts as inert protection. The consumption of oxygen diffusing into the cells is approximated using Michaelis-Menten kinetics. The problem is transformed to dimensionless units and solved numerically. Two regimes are identified, one that is diffusion limited and the other consumption limited. A regression is fit that describes the concentration at the center of the cells as a f...
A numerically efficient frequency domain method for analysis of non Linear multi degree of freedom systems Özer, Mehmet Bülent (2012-08-15) Linear structural models contain mass, stiffness and damping matrices as well as a forcing vector. Once these matrices and the forcing vector are known, the response can be calculated through the methods of linear algebra. The system matrices of the linear model do not contain any terms that depend on the system response vector, therefore the calculation of the system response do not require an iterative procedure. On the other hand, frequency domain analysis of non-linear structural models generally contai...
