Sun Tzu's essays The Art of War are the oldest known treatise on this topic but they have never been surpassed in terms of content and depth of understanding. They are characterised by concentrated wisdom on warfare. Compared to Carl von Clausewitz, Sun Tzu has a clearer vision, deeper understanding of preparation and combat itself and this makes him modern for eternity. Clausewitz wrote more than two thousand years later but he is more indebted to this period than Sun Tzu and this makes him rather obsolete nowadays even though some of his ideas are applicable, even though they can be applied only within the limitations of the moral and ethic values applied in a particular territory. If using the approach stemming from Sun Tzu's oriental war philosophy it is necessary to understand these ideas and to implement them correctly. In this respect we find it very important to point out to the incorrect trend that can be identified in the studies of western literature dealing with this war philosophy. Source

Three keys to the success of a patient access and flow initiative at the University of Mississippi Medical Center are: The creation of a patient placement center. The formation of multidisciplinary teams to address issues with throughput. The development of a rapid admissions unit. Source

Transported air pollutants receive increasing attention as regulations tighten and global concentrations increase. The need to represent international transport in regional air quality assessments requires improved representation of boundary concentrations. Currently available observations are too sparse vertically to provide boundary information, particularly for ozone precursors, but global simulations can be used to generate spatially and temporally varying lateral boundary conditions (LBC). This study presents a public database of global simulations designed and evaluated for use as LBC for air quality models (AQMs). The database covers the contiguous United States (CONUS) for the years 2001-2010 and contains hourly varying concentrations of ozone, aerosols, and their precursors. The database is complemented by a tool for configuring the global results as inputs to regional scale models (e.g., Community Multiscale Air Quality or Comprehensive Air quality Model with extensions). This study also presents an example application based on the CONUS domain, which is evaluated against satellite retrieved ozone and carbon monoxide vertical profiles. The results show performance is largely within uncertainty estimates for ozone from the Ozone Monitoring Instrument and carbon monoxide from the Measurements Of Pollution In The Troposphere (MOPITT), but there were some notable biases compared with Tropospheric Emission Spectrometer (TES) ozone. Compared with TES, our ozone predictions are high-biased in the upper troposphere, particularly in the south during January. This publication documents the global simulation database, the tool for conversion to LBC, and the evaluation of concentrations on the boundaries. This documentation is intended to support applications that require representation of long-range transport of air pollutants. Source

With its Unified Modeling Language UML standard Object Management Group (OMG) made modelling of system design popular. By introducing the Model Driven Architecture OMG provided the means to define dedicated modelling languages for different application domains and system design methodologies. Agent-based system design gained significant interest in the 1990s. Different approaches for the modeling of agent-based systems have been proposed and more recently metamodels for these approaches have been published. A standard is currently in progress by the OMG: the Agent Metamodel and Profile (AMP). The objective of AMP is to provide a metamodel and profile for extending UML with core capabilities to enable agents and agent-based software. This article is limited to providing that background information on how AMP fits into the OMG's approach to the core metamodel that is being considered for the AMP. © 2012 Springer-Verlag. Source

This paper addresses the use of quality attributes as a mechanism for making objective decisions about architectural tradeoffs and for providing reasonably accurate predictions about how well candidate architectures will meet customer expectations. Typical quality attributes important to many current systems of interest include performance, dependability, security, and safety. This paper begins with an examination of how quality attributes and architectures are related, including some the seminal work in the area, and a survey of the current standards addressing product quality and evaluation. The implications for both the customer and the system developer of employing a quality-attribute-based approach to architecture definition and tradeoff are then briefly explored. The paper also touches on the relationship of an architectural quality-attribute-based approach to engineering process and process maturity. Lastly the special concerns of architecting for system assurance are addressed. © 2008 IEEE. Source
