The purpose of present paper was to examine the relationship between central bank independence and inflation rate in Iran over 1960-2008. First, central bank independence has been accomplished through three indices including legal and real CBI indices and turnover rate of central bank governor index. Then, Augmented Dickey-Fuller test for model stationary of variables has been done by applying ...

The management of mineral fertilization using centrifugal spreaders requires the development of spread pattern characterization devices to improve the quality of fertilizer spreading. In order to predict the spread pattern deposition using a ballistic flight model, several parameters need to be determined and especially the velocity of the granules when they leave the spinning disc. This paper ...

Indicator-geostatistics based super-resolution mapping (IGSRM) is a popular super-resolution mapping (SRM) method. Unlike most existing SRM methods that produce only one SRM result each, IGSRM generates multiple equally plausible super-resolution realizations (i.e., SRM results). However, multiple super-resolution realizations are not desirable in many applications, where only one SRM result is...

A novel hydroturbine governor scheme based on networked control system (NCS) is proposed. The key problem of the scheme rest with the time delay existing in the data communication in NCS as the time delay may be a detriment to governor system stability and may degrade system robustness. In order to guarantee the governor system stable with time delay, the uncertain delay model is modeled as mul...

This paper presents analysis and comparative study of a novel high-torque three-phase switched reluctance motor (SRM) with magnetically isolated stator segments. In the proposed SRM, each segment has a concentric winding located on the center body of it and two diametrically opposite windings which form the motor phase. There are four salient poles in the stator segment. Two of them share their...

We present a methodology for designing reference tracking controllers for constrained, discrete-time piecewise affine systems. The approach follows the idea of reference governor techniques where the desired set-point is filtered by a system called the “reference governor”. Based on the system current state, set-point, and prescribed constraints, the reference governor computes a new set-point ...

The Watt centrifugal governor is a device that automatically controls the speed of an engine. Dating to 1788, it can be taken as the starting point for automatic control theory (see MacFarlane [5] and references therein). In this paper the system coupling the Watt-centrifugal-governor and the steamengine will be called simply the Watt Governor System (WGS). Landmarks for the study of the local ...
