Fuel diversification implies the selection of a mix of generation technologies for long-term electricity generation. The goal is to strike a good balance between reduced costs and reduced risk. The method of analysis that has been advocated and adopted for such studies is the mean-variance portfolio analysis pioneered by Markowitz (1959). However the standard mean-variance methodology, does not...

This paper discusses a new technique for controlling SVCs (Fixed Capacitor–Thyristor Controlled Reactor) in power systems with the aim of canceling the reactive current component of the load. A complete model of the SVC with its control circuit is set up and simulated in the EMTDC program. The generated harmonics from the proposed SVC controller are considered to design simple tuned filters to ...

Tendons are designed to take tensile load, but excessive load can cause overuse tendinopathy. Overuse tendinopathy results in extensive changes to the cells and extracellular matrix, resulting in activated cells, increase in large proteoglycans and a breakdown of the collagen structure. Within these pathological changes, there are areas of fibrocartilaginous metaplasia, and mechanotransduction ...

The face load factor KH, which in rating equations represents the load distribution over the common face width in meshing gears, is one of the most important items for a gear strength calculation. In the international standard for cylindrical gear rating, the ISO6336-1 [1], using method C, some formulas are proposed to get a value for this factor. But as the formulas are simplified, the result...

A continuum-based finite-element methodology is established for quantifying the stability of earthen embankments built on saturated soil deposits. Within the methodology the soil is treated as a fluid-solid porous medium, in which the soil skeleton’s constitutive behavior is modeled using a smooth elastoplastic cap model that features continuous coupling between deviatoric and volumetric plasti...

In this work we introduce a new algorithm for in-core parallel sorting integer keys which is based on the overpartitioning scheme introduced by Li and Sevcik [1]. The algorithm is devoted to clusters with processors running at different speeds i.e. correlated by a multiplicative constant factor. We compare experimentally this approach with another one related to the Parallel Sorting by Regular ...

For self-regulated learning to be effective, students need to be able to accurately monitor their performance while they are working on a task, use this as input for self-assessment of that performance after the task, and select an appropriate new learning task in response to that assessment. From a cognitive load perspective, monitoring can be seen as a secondary task that may become hard to m...

Load characteristics are the main factor to affect voltage stability. In addition, load modeling reflecting the actual load characteristics has been a well—known difficult problem and unsolved so far, It is mainly due to the fact that the load composition, amount and characteristics are always changing. This paper introduces the slip into the equivalent impedance load model to analyze load char...

The radiant time series method is a new method for performing design cooling load calculations, derived from the heat balance method. It effectively replaces all other simplified (non-heat-balance) methods such as the cool#zg load temperature difference~solar cooling load~cooling load factor method (CLTD/SCL/CLF), the total equivalent temperature difference~time averaging method (TETD/TA), and ...
