Internet has played an important part in the success of information technologies. With the growing and changing demands, there are many limitations faced by current Internet. A number of network testbeds are created for solving a set of specific problems in Internet. Traditionally, these testbeds are lacking of large scale network and flexibility. Therefore, it is necessary to design and implem...

Current trends towards the Future Internet are envisaging the conception of novel services endowed with context-aware and autonomic capabilities to improve end users’ quality of life. The Internet of Things paradigm is expected to contribute towards this ambitious vision by proposing models and mechanisms enabling the creation of networks of “smart things” on a large scale. It is widely recogni...

Quick-Start is an experimental extension of the Transmission Control Protocol (TCP) that uses explicit router feedback to speed up best effort data transfers. With Quick-Start, TCP endpoints can request permission from the routers along the path to send at a higher rate than allowed by the default TCP congestion control, which avoids the time-consuming Slow-Start. However, since Quick-Start TCP...

an efficiency-centred hierarchical model is developed to assess the performance ofwastewater treatment plants (wwtps). specifically, a new treatment performance index (tpi) hasbeen proposed to determine the overall treatment performance of wwtp by analysing the tpivalues and the weights of individual treatment phase for overall treatment performance. threemodules have been developed to examine ...

using current employee performance data to predict the future behavior of the applicants is an interesting area which can broaden new horizons of knowledge lay in the organization. because of inherent ambiguity and uncertainty, cognitive limitations of the human mind make unknown behaviors of very complex systems difficult to predict. as a consequence, it is necessary to model the imprecise mod...

prior experimental and theoretical background of the banki water turbine has been briefly presented. theoretical values of unit quantities have been compared with published experimental data as well as data obtained in the hydraulic lab at the university of tehran; from which, shortcomings of the existing theory in predicting the turbine performance has been highlighted. factors responsible for...

In the current Internet, standard TCP congestion control is based on segment loss events possibly assisted by simple explicit router feedback mechanisms like Explicit Congestion Notification (ECN). The performance of TCP congestion control can be improved if a more sophisticated Router Congestion Feedback (RCF) mechanism than ECN is used. One of such approaches is Explicit Window Adaptation (EW...
