Research ArticleOpen accessEvery word in the titleStatistical Models for Hardened Properties of Self-Compacting ConcreteArabi N.S. Al Qadi, Kamal Nasharuddin Bin Mustapha, Hashem Al-Mattarneh, Qahir N.S. AL-KadiProblem statement: For predicting workability and hardened properties of Self-Compacting Concrete (SCC) no well known explicit formulation. Approach: Statistical models were carried out to model the influence of key mixture parameter (cement, water to powder ratio, fly ash and super plasticizer) on hardened properties affecting the performance of SCC. Such responses included compressive strength at 3, 7 and 28 days … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,140 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Iterative Method for Algorithms Implementation on a Limited Dynamically Reconfigurable HardwareAbdellatif Mtibaa, Abdessalem B. Abdelali, Lotfi Boussaid, Elbey BourennaneIn this study we propose a framework and a combined temporal partitioning and design space exploration method for run time reconfigurable processors. Our objective is to help designers to implement an algorithm in limited FPGA area resources while respecting the execution time constraint. The algorithm to be implemented is represented by a task graph with different implementation alternatives (design points) … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,536 accessesView PDFCite
