BACKGROUND Little is known about the relationship between the opinions of inpatients and the degree to which hospitals are improving in performance over time. The aim of this study was to determine the personal assessment level of inpatients or their representatives regarding aspects of health care in an internal medicine ward. METHODS We carried out a questionnaire in September 2011 with 284...

In modern information and sensor systems the timely estimation of the carrier frequency of received signals is of critical importance. This paper presents the Digital Instantaneous Frequency Measurement (DIFM) technique, which can measure the carrier frequency of a received waveform within a fraction of a microsecond. The resulting frequency range, resolution and accuracy of the system are scal...

In this paper we present a Distributed Intelligent Fault Management (DIFM) system for communication networks. The overall architecture of the proposed system is based on a distributed cooperative multi-agent paradigm, with probabilistic networks as the framework for knowledge representation and evidence inferencing. We adopt the management by delegation paradigm [5] for network monitoring and i...

As one of the most widespread renewable energy technologies, photovoltaic power generation system provides great environmental and economic benefits. Achieving precise prediction for PV will greatly improve quality electric enhance stability operation. Inspired by powerful ability fuzzy logic to deal with uncertainty superiority machine learning handle time series prediction, a hybrid ensembled...

Instantaneous Frequency Measurement (IFM) devices are the essential parts of anyESM, ELINT, and RWR receiver. Analog IFMs have been used for several decades. However, thesedevices are bulky, complex and expensive. Nowadays, there is a great interest in developing a wideband, high dynamic range, and accurate Digital IFMs. One Digital IFM that has suitably reached allthese requirements is mono-bi...

With the explosive growth of e-payment industry, online transaction fraud has become one biggest challenges for business. The historical behavior information users provides rich digging into users' risk. While considerable efforts have been made in this direction, a long-standing challenge is how to effectively exploit user's behavioral and provide explainable prediction results. In fact, value...

industrial organizations are complex systems` where the interactions among the various functions such as sales, distribution, manufacturing, materials, finance, human resources and maintenance have to be man-aged towards a common purpose of delivering the customers satisfaction. however, since most of these or-ganizations have a `functional structure`, each function or department works towards ...
