desertification refers to land degradation phenomenon in arid, semi-arid and dry sub-humid areas, resulting from various factors including climate variation and human activities. for evaluation and mapping of desertification many research have been conducted leading to regional and local models. in this research, among different existing methods imdpa was selected and desertification intensity ...

Microbiology laboratories in Alberta, Canada, were surveyed to determine the quantitative interpretive criteria used to routinely read and report Gram stains. There was a wide variability in the quantitative reporting criteria cited for both cells and bacteria, with only 11 of 32 (34.4%) laboratories surveyed using the criteria recommended by the external proficiency-testing program. Lack of st...

I. Abstract—Ontological concept evaluation is a difficult task. Till now, it is done either by domain expert or a knowledge base (thesaurus, ontology, etc.). In this research, we propose a new evaluation method based on a large web document collection, several context definitions deduced from it and three criteria. It provides a support for either a domain expert or a novice user. Moreover, it ...

Predicting the epileptic seizure is challenging biomedical problem. EEG signal includes enormous information. Few relevant parameters are expected in the field of recognition and diagnostic purposes. Seizure detection and classification system has been designed and developed. The system uses computer based procedures to detect seizure and classified normal and abnormal subjects. Intelligent com...

AIMS Our goal was to develop historical criteria for the diagnosis of vasovagal syncope. METHODS AND RESULTS We administered a 118-item historical questionnaire to 418 patients with syncope and no apparent structural heart disease. The prevalence of each item was compared between patients with positive tilt tests and those with syncope of other, known causes. The contributions of symptoms to ...

The Common Criteria (CC) certification framework defines a widely recognized, multi-domain certification scheme that aims to provide security assurances about IT products to consumers. However, the CC scheme does not prescribe a monitoring scheme for the CC practice, raising concerns about the quality of the security assurance provided by the certification and questions on its usefulness. In th...

We generate a series of pseudopotentials to examine the relationship between pseudoatomic properties and solid-state results. We find that lattice constants and bulk moduli are quite sensitive to eigenvalue, total-energy difference and tail norm errors, and clear correlations emerge. These trends motivate our identification of two criteria for accurate transition metal pseudopotentials. We find...

Standardized CT-based criteria used for lymphoma staging and follow-up and the current role of FDG-PET are reviewed. The current CT-based International Workshop Criteria (IWC) still have the main advantage of representing standardized criteria allowing comparability of clinical trials in patients with lymphoma. However, functional imaging with integrated IWC and FDG-PET provide more accurate re...
