OBJECTIVES To assess how often stratified randomisation is used, whether analysis adjusted for all balancing variables, and whether the method of randomisation was adequately reported, and to reanalyse a previously reported trial to assess the impact of ignoring balancing factors in the analysis. DESIGN Review of published trials and reanalysis of a previously reported trial. SETTING Four l...

In this paper, the static balancing of existing spatial and planar parallel manipulators by the addition of balancing elements is addressed. Static balancing is defined here as the set of conditions on manipulator dimensional and inertial parameters which, when satisfied, ensure that the weight of the links does not produce any force (or torque) at the actuators for any configuration of the man...

Assembly line balancing is a key for organizational productivity in terms of reduced number of workstations for a given production volume per shift. Mixed-model assembly line balancing is a reality in many organizations. The mixed-model assembly line balancing problem comes under combinatorial category. So, in this paper, an attempt has been made to develop three genetic algorithms for the mixe...

The feature of load sharing or load balancing involves migration of running processes from highly loaded workstations of a network to the lightly-loaded or idle workstations of the network. This paper describes load balancing techniques to share the workload of the workstations belonging to a particular network to gain better performance from the overall network. The mechanisms of load informat...

Relaxed balancing has become a commonly used concept in the design of concurrent search tree algorithms. The idea of relaxed balancing is to uncouple the rebalancing from the updating in order to speed up the update operations and to allow a high degree of concurrency. Many di erent relaxed balancing algorithms have been proposed, especially for red-black trees and AVL trees, but their performa...

calling r ∈ Z+ the balancer corresponding to the balancing number n. The numbers 6, 35, and 204 are examples of balancing numbers with balancers 2, 14, and 84, respectively. Behera and Panda [1] also proved that a positive integer n is a balancing number if and only if n2 is a triangular number, that is, 8n2 + 1 is a perfect square. Though the definition of balancing numbers suggests that no ba...

This study presents a new dispatch model (SCSP) for a CSP plant based on a dynamic programing algorithm. The purpose is to investigate the cost of balancing a CSP plant in the Spanish electricity market. Results are presented for a parabolic plant in the Spanish market for years 2009, 2010 and 2011 using solar availability data at the Plataforma Solar, Andalucia, Spain. The variation of balanci...
