Performance Of Self-Compacting Concrete, Mohamed Samir Rushdy Jun 2004

Performance Of Self-Compacting Concrete, Mohamed Samir Rushdy

Archived Theses and Dissertations

Concrete compaction is one of the indispensable fundamentals of concrete manufacturing. However, thorough compaction cannot always be insured. This can be wholly or partially encountered in congested sections, out-of reach deep foundations and narrow or irregular precast components. On the other hand, typical vibrators were considered as contributor to health hazards to workers. Self-compacting concrete (SCC) is an emerging concrete where the cohesive yet flowable consistency of the concrete itself secures adequate placement with high level of homogeneity and little or no segregation. Such concrete is primarily achieved by incorporating admixtures that is referred to as viscosity modifying (VM) admixtures …


Performance Evaluation Of Auc Backbone Network Using Simulation And Monitoring Tools, Nabawia Khalil Abdel-Karim Feb 2004

Performance Evaluation Of Auc Backbone Network Using Simulation And Monitoring Tools, Nabawia Khalil Abdel-Karim

Archived Theses and Dissertations

Networks in the past were defined by the traffic they carried. The network management systems that can track performance statistics, alarms and diagnostics are usually called operations support systems. As number of applications carried over a network grew, networks cannot scale economically. They become large, complex and expensive. Network performance became an important issue to network designers, operators and implementers to design, implement and maintain scalable, reliable and resilient networks. In this research, we developed a comparative analysis for two tools commonly utilized to aid network operations support to arrive at decisions related to network scalability, performance evaluation and renewal. …
