water quality assessment provides a scientific basis for water resources development and management. this case study proposes a factor analysis- hopfield neural network model (fhnn) based on factor analysis method and hopfield neural network method. the results showed that the factor analysis (fa) technique was introduced to identify important water quality parameters. results revealed that bio...

abstractone challenge face political system is implementation national development. there are various models for national development. some countries have relied on import model, but other has emphasis on their indigenous, the purpose of this study is designing intelligence development model in iranian national context. based on the selected theory building methodology, we have theorized intell...

A research agenda for multimedia networking is presented. The discussion centers around an extended reference model (XRM) that includes networking and multimedia computing devices. The XRM explicitly models the broadband and media processors, the multimedia network and the services and applications network. The interface between these models is given by quality of service and service abstractio...

Within analytical customer relationship management (CRM), customer acquisition models suffer the most from a lack of data quality because the information of potential customers is mostly limited to socio-demographic and lifestyle variables obtained from external data vendors. Particularly in this situation, taking advantage of the spatial correlation between customers can improve the predictive...

This paper presents a methodology for assessing and improving the quality of information provided by corporate wikis. Regarding the assessment, we present two KPIs for measuring relative demand and relative usefulness of wiki articles, including corresponding processes and data model. In regard to improving quality, we use the KPIs to classify the articles. For this classification, we introduce...

—Quality of service (QoS) architectures have been required in recent years to support a wide range of distributed applications, particularly in wide-area systems. In the context of QoS information management associated with QoS activities, QoS information modeling and mapping enable QoS architectures to be developed independently of the underlying environment and/or application. This paper prov...

This paper discusses a model for evaluating the Quality of Service of a Campus-Wide network. The main goal is to achieve a mathematical model that can be applied to any network, providing its availability. The network where it will be tested has more than 5000 nodes with SNMP managed network devices. The model discards the classical approach to QOS that considers parameters such as delay or jit...

background : despite many progresses in the improvement of care status and the management of acute coronary syndrome, cares quality is far from the desirable conditions. today, due to the great emphasis on resources management, costs control, the effectiveness of patient care, improving quality and responsibility, the good patient care is necessary. two dimensions are referred for improving the...
