In this paper we present a new TCP retransmission algorithm to recover from multiple non-congestion(transmission) packet drops from the same TCP window. This algorithm will help end-to-end error discriminators to improve TCP performance over lossy and heterogeneous networks. The simulation results shows that the proposed algorithm has increased TCP performance over different error rates without...

A heat exchanger network (HEN) for the process of methanol synthesis has been studied by combination of pinch design method and the application of “Twisted Tube” heat exchanger units as a new technology. The HEN is reconstructed based on the full utilization of maximum allowable pressure drops for the process hot and cold streams. An algorithm is developed to generate design procedure for twist...

the desire and drive for excellence in any endeavor in life requires an effort from the individual; in addition it requires a constellation of features around such individuals that help them to become successful. for surgeons, it is the operating room staff, the administrative and medical assistants and our residents and fellows. however, perhaps the most important contribution to a physician’s...

This paper proposes a novel optimization algorithm inspired by water flowing and shaking behaviors in a vessel. Water drops in our algorithm flow to the gradient descent direction and are sometimes shaken for getting out of local optimum areas when most water drops fall in local optimum areas. These flowing and shaking operations allow our algorithm to quickly approach to the global optimum wit...

163904-4747-IJECS-IJENS © August 2016 IJENS I J E N S Abstract— The intelligent water drops (IWD) algorithm was introduced in 2007 by Hamed Shah Hosseini, and has been successfully implemented to solve many types of optimization problems, especially traveling salesman problem (TSP). The algorithm works by imitating the behavior of the natural river water drops. Principally, the algorithm finds ...

In this paper, a hybrid algorithm based on modified intelligent water drops algorithm and learning automata for solving Steiner tree problem is proposed. Since the Steiner tree problem is NP-hard, the aim of this paper is to design an algorithm to construct high quality Steiner trees in a short time which are suitable for real time multicast routing in networks. The global search and fast conve...

Many previous attempts to improve TCP performance over lossy links especially error discriminators did not propose a comprehensive response in case of non-congestion drops. In this paper we propose a new algorithm to control TCP congestion window reaction to transmission (non-congestion) drops. This algorithm will be the first step for more comprehensive solution. The new algorithm managed to i...

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Measurement of solar radiance demands expensive devices to be used. Alternatively, estimator models are used instead. In this paper, a new method based on the empirical equations is introduced to estimate the monthly average daily global solar radiation on a horizontal surface. The proposed method uses Intelligent Water ...

Abstract Travelling salesman problem (TSP) is a well known combinatorial optimization which has drawn colossal attention due to its eclectic range of applications. In this article, we have proposed two modified versions intelligent water drops (IWD) algorithm. The first one the enhanced IWD (e-IWD) algorithm solve single objective TSP. second modification, e-IWD been extended multi-objective IW...
