An evaluation of load sharing algorithms for heterogeneous distributed systems
… a job at other nodes than the originating one. Load sharing algorithms use this ability to distribute work around the system in order to achieve greater efficiency. This is reflected in substantially reduced response times. In the majority of studies the systems on which load sharing has been …

Local control of multiple module converters with ratings-based load sharing
… or master controller. A power ratings-based load sharing scheme that allows for uniform and non-uniform sharing is introduced. Focus is given to an input series, output parallel (ISOP) configuration and modules with a push-pull topology. Sensorless current mode (SCM) control is digitally …

Multiple Input Single Output Converter with Uneven Load Sharing Control for Improved System Efficiency
… The premise of this thesis is to create uneven load current sharing between the converters at different loading conditions in order to maximize the efficiency of the overall MISO converter. The goal is to find a proper ratio of current from each converter to the total load current of the MISO …

Use of Compliant Interbody Force Sensing Grafts to Compare Load Sharing Properties of Unidirectional and Bidirectional Multilevel Dynamic Translational Anterior Cervical Plates
… cervical plates have emerged to maintain load sharing as an arthodesis matures. Dynamic plates can translate bidirectionally (allow translation in compressive and tensile loads), or unidirectionally (allow translation in compression, but maintain its position under tensile loads). The …

Experimental and Numerical Study on Bolted/Bonded Composite Joints for Aircraft
… research efforts have been focused on the load sharing and strength improvement. The load sharing has been analyzed experimentally using instrumented bolts and numerically using finite element modelling. The strength analysis has been studied experimentally. The present research was …

Interpersonal Emotion Dynamics in Mother-Daughter Dyads during Adolescence
… examined in three studies. In Study 1, emotional load sharing (i.e., the distribution of the burden of emotional distress among relationship partners) during adolescent social stress was examined as it related to physical and relationship closeness. Dyads were randomly assigned to either have …

Structural System Reliability with Application to Light Steel-Framed Buildings
… individual component due to the likelihood of load redistribution and al- ternate load paths, however such conservatism cannot be guaranteed without an explicit system-level safety check. As a result, component-based structural designs can lead to both over-conservative components and a …

Control of DC Power Distribution Systems and Low-Voltage Grid-Interface Converter Design
… dc systems: (a) system-level control to improve load sharing, voltage regulation and efficiency; (b) design of a high-efficiency interface converter to connect dc microgrids with the existing low-voltage ac distributions, with a special focus on common-mode (CM) voltage attenuation. Droop control …

Effectiveness of high strength repair mortars in structural patch repairs of concrete members under axial compression
… ability of the repair material to contribute to load sharing in the repaired element under service loads. Three commercially available high strength cement-based repair materials were tested for their strength, elastic modulus, shrinkage and creep properties. The tested repair material properties …

Modeling and Control of Parallel Three-Phase PWM Converters
… of the parallel converters requires an explicit load-sharing mechanism. In order to have a modular design, a droop method is recommended. Traditionally, however, a droop method has to compromise between voltage regulation and load sharing. After parametric analysis, a novel droop method using a …

Analysis of some simple policies for dynamic resource allocation
… investigated for dynamic resource allocation in load sharing networks with Erlang-type statistics. The emphasis is on the performance of simple allocation strategies that can be implemented on-line. The resource allocation problem is formulated as a stochastic optimal control problem. Variants of …
