Unbalanced Exchange Flow
… in one direction than the other, the flow is unbalanced. Whilst the flow rate of balanced exchange flow has previously been measured experimentally and described theoretically, prior to the work herein there has been no theoretical description of unbalanced exchange flow, only experimental …

Affinity scheduling of unbalanced workloads
Shared memory multiprocessor systems are becoming increasingly important and common. Multiprocessor environments are significantly different from uniprocessor environments, raising new scheduling issues that need to be considered. A fundamental scheduling issue arises in situations in which a …

State estimation of unbalanced power systems
… allows the calculation of state estimates for unbalanced electric power systems. This model incorporates the effects of mutually coupled conductors, earth return paths, unbalanced device configurations, and multiple voltage references. Development of the new model appeals to multiport network …

Security of Unbalanced Oil-Vinegar Signature Scheme
… the algebraic attack for the randomly built unbalancedoil-vinegar signature systems with different characteristics. Then we explore the security of those general oil-vinegar systems under F4 algorithm attack.</p>

Construction of Some Unbalanced Designs for the Partition Problem
… literature, many vector-at-a time and unbalanced methodologies are available for the selecting the best normal population. However, the literature is not that rich for the partition problem. In this thesis, an unbalanced methodology of sampling along the lines of Mukhopadhyay and …

Graphical and Bayesian Analysis of Unbalanced Patient Management Data
… innovative graphics to help describe a highly unbalanced dataset and to carry out Bayesian analyses to determine which of five devices best manages patients. An initial Bayesian analysis compared a machine-identical beta-binomial model to a machine-specific beta-binomial model. The response …

Calculation of Unbalanced Magnetic Pull in Cage Induction Machines
… will increase the eccentricity. This is called unbalanced magnetic pull (UMP). The first part of the work presented in this dissertation develops theoretical models which allow the calculation of the UMP in cage induction motors due to static rotor eccentricity. These account for any winding …

Effects of voltage unbalanced supplies on energy-efficient motors
Eskom DSM has recently introduced an Energy Efficiency (EE) Motor program, which provides incentives to industrial customers to retrofit standard motors with EE motors. The main objective of the program is to realize energy savings through the replacement of standard (STD) induction motors with …

Operation of induction machines in the presence of unbalanced supplies
… voltages. However, the power system experiences unbalanced voltages, overvoltages, undervoltages, etc, which are seen at the motor terminals. The South African Electricity Supply Utility (Eskom) supplies the commercial and industrial systems with a line voltage range of 400V +- 10%. An Induction …

A study of some unbalanced fault conditions of power systems
… severe types of fault wherein the system becomes unbalanced due to a fault involving only one or two phases. In contrast, this thesis deals with the unbalanced type of fault on a system. The necessary equations are derived and simple problems are solved for three major types of faults, i.e., the …

The microstructure and properties of unbalanced magnetron sputtered CrN[x] coatings.
The most widely used surface treatment to protect engineering components is the deposition of hard chromium by electroplating. The coatings are known to be quite thick (up to 20 mum), reasonably hard (-HV1000), but contain micro-cracks. This wet deposition process is well understood, but it has …

An Analysis of Health Sector Trends: Incorporating Theories of Unbalanced Growth
International studies of health care expenditures find income elasticities of aggregate demand for health care in the range of 1.0 to 1.5. Applying these same models to a U.S. time series using ordinary least squares to estimate a cointegrating relationship yields estimates in this range. …
