This paper shows the Matlab/Simulink implementation of the current control in a single phase full-bridge power inverter. In order to increase the performances of the power inverter an LC filter is connected at the input. Mathematical modelling of the power inverter is based on the switching functions. Unipolar asymmetric PWM modulation method, and hysteresis current control will be analyzed for...

a chaotic optimization algorithm (coa) based approach for the robust coordinated design of the upfc power oscillation damping controller and the conventional power system stabilizer has been investigated in this paper. chaotic optimization algorithms, which have the features of easy implementation, short execution time and robust mechanisms of escaping from local optimum, is a promising tool fo...

BACKGROUND In most countries, genetic carrier screening is neither offered, nor embedded in mainstream healthcare. Technological developments have triggered a two-fold transition in carrier screening: the expansion from screening one single disorder to many disorders simultaneously, and offering screening universally, regardless of ancestry. This study aims to identify general and population-sp...

Scaling up an emergency obstetric and neonatal care (EmONC) programme entails reaching a larger number of people in a potentially broader geographical area. Multiple strategies requiring simultaneous attention should be deployed. This paper provides a framework for understanding the implementation, scale-up and sustainability of such programmes. We reviewed the existing literature and drew on o...

UNLABELLED Child neglect is an ecosystemic problem with a great variety of risk factors to consider and, therefore, it requires a multimodal and individualized intervention. Although such an intervention is better for the families, it represents a great challenge for the evaluation process. OBJECTIVES The purpose of this study is to document, using Dane and Schneider's model (1998), the diffe...

AIM This paper reviews the Productive Ward: Releasing Time to Care™ literature, identifying and discussing the key characteristics that may contribute to successful implementation. BACKGROUND It is 5 years since the official UK launch of the Productive Ward, and the Republic of Ireland commenced a phased, national implementation programme in 2011. Thus it is timely to reflect on the implement...

This paper discusses what is needed to make MIS into a coherent research field. It defines 3 main needs: 1. Clarification of reference disciplines. 2. Definition of the dependent variable. 3. Building a cumulative tradition. It reviews the relationship of MIS to computer technology and to practice and assess the publishing inlets for MIS
