The use of rigid overlays has become increasingly popular. The main purpose of an overlay is to extend the service life of the structure and increase the structural performance and durability of a wearing surface. The superior ductility and durability characteristics of engineered cementitious composites (ECC) suggest that they could be used as an attractive alternative to conventional concrete overlay materials. In this study, the performance of ECC overlay designed at different thicknesses is investigated by laboratory experiments. Micro-silica concrete (MSC), generally used as an overlay material, is also prepared as a control mixture. The test results show that, for the same geometry and loading conditions, layered ECC beams have significantly increased both load-carrying capacity and deformability, and show better crack width control in comparison with MSC composite beams. As the overlay material, ECC is also found to be effective in eliminating the reflective cracking and delamination failure in repaired systems.

Performative architecture as a guideline for transformation Defense Line of Amsterdam Albayrak, Canan; Tuncer, Bige (2011-09-24) Performance as an architectural design paradigm has been emerging during the recent years. We have developed an understanding that we formalized as a taxonomy for performative architecture that considers performance from three points of view: health, safety and security performance; functional and efficiency performance; and psychological, social, cultural, and esthetic performance. This paper focuses on a design project that explores these ideas as a performative architecture proposal. The project focuses ...
Automatic eye tracking and intermediate view reconstruction for 3D imaging systems Bediz, Yusuf; Akar, Gözde; Department of Electrical and Electronics Engineering (2006) In recent years, the utilization of 3D display systems became popular in many application areas. One of the most important issues in the utilization of these systems is to render the correct view to the observer based on his/her position. In this thesis, we propose and implement a single user view rendering system for autostereoscopic/stereoscopic displays. The system can easily be installed on a standard PC together with an autostereoscopic display or stereoscopic glasses (shutter, polarized, pulfrich, and...
e-Government adoption model based on theory of planned behavior: Empirical validation Özkan Yıldırım, Sevgi (2011-10-01) The e-Government phenomenon has become more important with the ever increasing number of implementations worldwide. A model explaining the e-Government adoption and the related measurement instrument - a survey - had been developed and validated in this study. In a post Technology Acceptance Model (TAM) approach, theory of planned behavior (TPB) was extended to fit the requirements of e-Government context. The adoption of student loans service of the higher education student loans and accommodation associat...
MULTI-THREADED ARCHITECTURES AND BENCHMARK TESTS FOR REAL-TIME MULTI-VIEW VIDEO DECODING Akar, Gözde; TEKALP, AHMET MURAT (2009-07-03) 3D video based on multi-view representations is becoming widely popular. Real-time encoding/decoding of such video is an important concern as the number and resolution of views increase. We present systematic methods for design and optimization of real-time multi-view video encoding/decoding algorithms using multi-core processors and provide benchmark results. The proposed multi-core decoding architectures are fully compliant with the current JVT-MVC international standard, and enable multi-threaded process...
Architectures for multi-threaded MVC-compliant multi-view video decoding and benchmark tests Akar, Gözde; Akar, Gözde; Tekalp, A. Murat (Elsevier BV, 2010-06-01) 3D video based on stereo/multi-view representations is becoming widely popular. Real-time encoding/decoding of such video is an important concern as the number and spatial/temporal resolution of views increase. We present a systematic method for design and optimization of multi-threaded multi-view video encoding/decoding algorithms using multi-core processors and provide benchmark results for real-time decoding. The proposed multi-core decoding architectures are compliant with the current MVC extension of H...
