advanced data mining techniques can be used in universities classification, discovering specific patterns in the determination of successful students, design of a plan or a teaching method and finding critical points of financial management. in this article, we proposed a method to predict the rate of student enrollment in coming years. the data for this research were from data sets of voluntee...
In medical studies, measures are required to reveal the effect of exposures and interventions and also the precision of measurements. This paper aimed to introduce the measures of effect and agreement and inferences about them in these studies. Principles and method of calculating measures of effect and agreement and inference about them were presented for all types of medical studies taking in...
BACKGROUND Results from hemolyzed, icteric, and lipemic samples may be inaccurate and can lead to medical errors. These preanalytical interferences may be detected using visual or automated assessment. Visual inspection is time consuming, highly subjective and not standardized. Our aim was to assess the comparability of automated spectrophotometric detection and visual inspection of lipemic, ic...
AIM To determine interobserver and intra-observer agreement in the assessment of cytological grade and intraduct necrosis in pure duct carcinoma in situ (DCIS) of the breast. METHODS Sixty unselected cases with illustrated diagnostic criteria were circulated to 19 practising histopathologists. RESULTS Overall agreement was moderate for cytological grade in three categories: 71% agreement; w...
High-precision automatic identification and mapping of forest tree species composition is an important content resource survey monitoring. The airborne hyperspectral image contains rich spectral spatial information, which provides the possibility high-precision classification species. Few-shot learning, as application deep has become effective method classification. Prototypical networks (P-Net...
INTRODUCTION An accurate determination of body temperature in critically ill patients is a fundamental requirement for initiating the proper process of diagnosis, and also therapeutic actions; therefore, the aim of the study was to assess the accuracy and precision of four noninvasive peripheral methods of temperature measurement compared to the central nasopharyngeal measurement. METHODS In ...
Quantitative trading is an integral part of financial markets with high calculation speed requirements, while no quantum algorithms have been introduced into this field yet. We propose for high-frequency statistical arbitrage in work by utilizing variable time condition number estimation and linear regression.The algorithm complexity has reduced from the classical benchmark O(N^2d) to O(sqrt(d)...
BACKGROUND GRADE was developed to address shortcomings of tools to rate the quality of a body of evidence. While much has been published about GRADE, there are few empirical and systematic evaluations. OBJECTIVE To assess GRADE for systematic reviews (SRs) in terms of inter-rater agreement and identify areas of uncertainty. DESIGN Cross-sectional, descriptive study. METHODS We applied GRA...
land use mapping using fuzzy classification: case study in three catchment areas in hamedan province
land cover mapping is important for many planning and management activities. today, satellite images and remote sensing techniques are extensively used in all sectors including agriculture and natural resources because they provide updated data and high analyzing abilities. in this study, in order to produce land cover map for the northern part of hamedan province , digital satellite data irsp6...
In this research, the capability of Rapid Eye satellite imagery for mapping the crown distribution of oak trees in Zagros forests was investigated in the Dashtebarm forest area of Kazeroun, Fars province. In this study, data quality was investigated geometrically and radiometrically and geometric correction of the images was done using a linear method and using precision ground control ...
