BACKGROUND The aim of the study was to develop a virtual microscopy enabled method for assessment of Ki-67 expression and to study the prognostic value of the automated analysis in a comprehensive series of patients with breast cancer. METHODS Using a previously reported virtual microscopy platform and an open source image processing tool, ImageJ, a method for assessment of immunohistochemica...

Bone age assessment (BAA) of unknown people is one of the most important topics in clinical procedure for evaluation of biological maturity of children. BAA is performed usually by comparing an X-ray of left hand wrist with an atlas of known sample bones. Recently, BAA has gained remarkable ground from academia and medicine. Manual methods of BAA are time-consuming and prone to observer variabi...

introduction: it is recommended that the physician apply at least a semi-quantitative segmental scoring system in myocardial perfusion spect.  we aimed to assess the agreement between automated semi-quantitative analysis using qps (quantitative perfusion spect) software and visual approach for calculation of summed stress  score (sss), summed rest score (srs) and summed difference score (sds). ...

OBJECTIVES Visual inspection is generally used to assess breast density. Our study aim was to compare visual assessment of breast density of experienced and inexperienced readers with semi-automated analysis of breast density. METHODS Breast density was assessed by an experienced and an inexperienced reader in 200 mammograms and scored according to the quantitative BI-RADS classification. Bre...

The need to interpret imprecise diagrams (those with malformed, missing or extraneous features) occurs in the automated assessment of diagrams. We outline our proposal for an architecture to enable the interpretation of imprecise diagrams. We discuss our preliminary work on an assessment tool, developed within this architecture, for automatically grading answers to a computer architecture exami...

The acquisition of procedural skills requires learning by doing. Ideally, a student would receive real-time assessment and feedback as he attempts practice problems designed to exercise the targeted skills. This paper describes an automated assessment and feedback capability that has been applied to training for a complex software system in widespread use throughout the U.S. Army. The automated...

Automated assessment technologies have been used in education for decades (e.g., computerised multiple choice tests). In contrast, Automated Essay Grading (AEG) technologies: have existed for decades; are ‘good in theory’ (e.g., as accurate as humans, temporally and financially efficient, and can enhance formative feedback), and yet; are ostensibly used comparatively infrequently in Australian ...

Information gathering is an essential part of acute vulnerability assessment, especially when the whole process is automated. In this context, host Operating System detection must be precise, even when networks are well defended. We present an original Operating System detection method, based on temporal response analysis. As a proof of concept, we release the open source tool called RING – for...

samples of participants’ writing were scored by two raters using toefl writing scoring rubric. the readability index of each text was calculated through the use of six readability formulae and graphs, i.e., flesch-kincaid index, reading ease index, fog index, smog formula, fry’s graph, and dale-chall readability index. the scores given to each essay were later compared to the obtained readabili...
