Declarative visualization is a paradigm in which the process of visualization is treated as a mapping from some domain (typically a program) to an image. One means of declaring such mappings is through the use of rules which specify the relationship between the domain and the image. This paper examines the computational power of such rule-based mappings. Computational power is measured using th...

In many image processing applications the image quality should be improved to support the human perception. The image quality evaluation by the human observers is, however, heavily subjective in the nature. Different observers judge the image quality differently. In many cases the relevant part of image information which is perceived by the observer should reach a maximum. In this work we prese...

In the late 1980s and 1990s, the rise in the need for increasingly sophisticated security in information systems led to the creation of standards such as TCSEC, ITSEC and CTCPEC to aid in the assessment of security products for their suitability in the protection of national security. These standards have evolved into the Common Criteria: a set of fundamental principles with a basis in best pra...

BACKGROUND The Pulmonary Embolism Rule-out Criteria (PERC) rule is a clinical diagnostic rule designed to exclude pulmonary embolism (PE) without further testing. We sought to externally validate the diagnostic performance of the PERC rule alone and combined with clinical probability assessment based on the revised Geneva score. METHODS The PERC rule was applied retrospectively to consecutive...

www.aafp.org/afp Volume 88, Number 2 ◆ July 15, 2013 Is there a clinical prediction rule that can reliably exclude the presence of a pulmonary embolism (PE), and thus avoid the use of computed tomography (CT) in patients believed to be at very low risk? Bob: Let’s start with a case. A 42-year-old woman presents to your clinic saying that she awoke that morning with pleuritic right infrascapular...

This clinical policy from the American College of Emergency Physicians is the revision of a 2003 clinical policy on the evaluation and management of adult patients presenting with suspected pulmonary embolism (PE).(1) A writing subcommittee reviewed the literature to derive evidence-based recommendations to help clinicians answer the following critical questions: (1) Do objective criteria provi...

This paper proposes a new framework for incremental learning based on accuracy and coverage. Classified addition of example into four cases, two inequalities for accuracy and coverage are obtained. The proposed method classifies a set of formulae into three layers: rule layer, subrule layer and non-rule layer by using the inequalities obtained. Then, subrule layer plays a central role in updati...
