    Abstract: In this paper we study the uniform approximation of the cut function by smooth sigmoid functions such as Nelder and Turner–Blumenstein–Sebaugh growth functions. To illustrate the use of one of the models we have fitted the model to the “classical Verhulst data”. Several numerical examples are presented throughout the paper using the contemporary co...

    Abstract: The adverse effects of elevated temperatures on the properties of the fresh concrete include increased water demand, shorter setting time and increased slump loss. Superplasticizer (SP) is important to enhance the workability and setting time of concrete under hot weather, hence, an experimental investigation was conducted to determine the effect o... Show More

    Abstract: Software Defined Networking (SDN) is an approach to the deployment of future network infrastructures. SDN allows deal with different configurations to a crescent amount of virtualized network devices. In this paper, we offer a framework to support a number of network configurations through computational modeling and deployment of data paths between... Show More
