Load balancing is one of the best efficient methods for performance improvement of cluster system. Recently, WLC algorithm is used for the load balancing of cluster system. But, the algorithm also has load imbalance between servers, because it uses inaccurate static load status of servers. In this paper, I suggest a more efficient dynamic load balancing algorithm base on various load status inf...

Distributed system may be considered as a collection of resources shared by different users. Distributed systems provide methods for sharing and aggregation of resources. Resources may be storage systems, computer machines, hardware devices and other specialized devices. Load balancing is a technique which can be used to improve the performance of distributed system by allowing load migration f...

We review a nonlinear balancing approach presented in 2000. Unlike the method introduced by Scherpen (1994), which requires the solution of PDE’s, the novel method is computationally efficient and works also for unstable systems. First, we argue that a generalization for balancing nonlinear systems should be based upon three principles: 1) Balancing should be defined with respect to a nominal f...

In this paper by using numerical evaluation the effect of balancing drupes of water hammer on tunnels lining is considered. In case of not arrangment of these reservoirs, the tunnel lining will be damaged of cyclic powers of water hammer. In this research, function of balancing reservoir of water hammer on cover of tunnels to the barriers’ turbine is simulated by numerical methods and Plaxis 3D...

The balancing Neumann-Neumann (BNN) and the additive coarse grid correction (BPS) preconditioner are fast and successful preconditioners within domain decomposition methods for solving partial differential equations. For certain elliptic problems these preconditioners lead to condition numbers which are independent of the mesh sizes and are independent of jumps in the coefficients (BNN). Here w...

The control ability which changes the coordination pattern of masticatory muscles in the Maximal voluntary clenching was investigated in the correlativity, using the electromyogram and the Dental-Prescale system on ten normal subjects. Even the insignificant correlative Activity index to the balancing point of occlusal force was shown, though the anteroposterior control index (CA/P) marked slig...

the task of balancing of assembly lines is well-known in mass production system but this problem is np-hard even for the simple straight line. therefore, utilizing heuristic methods for these problems is totally unquestionable. furthermore, in line with balancing problems, heuristic methods are the foundation of the metaheuristic methods, thus it seems to be necessary to use more efficient heur...

Although a large number of users are using P2P systems, the ability of these systems to provide services with quality is questioned. A load balanced P2P system can provide services with smaller failure rate and better performance; hence, service quality of the system can be improved. Cluster systems have been adopted for services which are tolerant to faults. Although a cluster structure improv...

This paper investigates the channel assignment problem of dual-band PCS systems where single-band and dual-band handsets co-exist. Load-balancing channel assignment schemes are proposed to improve the system performance. To balance the loads of both bands, the BSC selects a band to serve a call request of a dual-band handset based on the loads of both bands. In addition, a channel re-assignment...

The problem of design targets reduction and balancing among subsystems is addressed. A new approach is proposed that aims at reducing the number of targets used to quantify the performance of an engineering system, consisting of several subsystems, using the properties of system norms. The proposed approach also provides a systematic means of balancing the cascaded targets among the constituent...
