Many business situations such as events, products and services, are often described in a hierarchical structure. When we use case-based reasoning (CBR) techniques to support business decision-making, we require a ...

The traditional min-cut problem involves finding a cut with minimum weight between two specified vertices. The planar multiway cut problem is a NP-hard generalization of the min-cut problem. It involves separating a weighted ...

Evaluating the network reliability is an important topic in the planning, designing, and control of systems. The minimal cut (MC, an edge set) set is one of the major and fundamental tools for evaluating the network ...

For conventional direct torque control (CDTC) methods, there are usually undesired torque and flux ripples mainly for two reasons. First, the vectors selected are not necessary the best. Secondly, one-step delay influence ...

Many real-world systems are multistate systems composed of multistate components in which the reliability can be computed in terms of the lower bound points of level d, called d-MCs. Such systems (electric power, transportation, ...

Linear programming (LP) is the core model of constrained optimization. The Simplex method (Simplex in short) has been proven in practice to perform very well in small- or medium-sized LP problems. A new algorithm called ...

We present a simple semiparametric model for tting subject-speci c curves for longitudinal data. Individual curves are modelled as penalized splines with random coe cients. This model has a mixed model representation, and ...

A simple portable light meter for use with fiber-optic microprobes was developed. The meter has a flat spectral quantum responsivity for 400 to 700 nm light (photosynthetically available radiation, PAR). With scalar ...

In this paper, a modified direct torque control (DTC) for permanent-magnet synchronous machines, which enables important torque- and flux-ripple reduction by using voltage vectors with variable amplitude and angle, is ...

Estimation of evapotranspiration from a crop field is of great importance for detecting crop water status and proper irrigation scheduling. The Penman-Monteith equation is widely viewed as the best method to estimate ...
