OBJECTIVE This paper aims at developing an automated gastroscopic video summarization algorithm to assist clinicians to more effectively go through the abnormal contents of the video. METHODS AND MATERIALS To select the most representative frames from the original video sequence, we formulate the problem of gastroscopic video summarization as a dictionary selection issue. Different from the t...

The Work Extrinsic and Intrinsic Motivation Scale (WEIMS) is an 18-item measure of work motivation theoretically grounded in self-determination theory (Deci & Ryan, 2000). The purpose of the present research was twofold. First, the applicability of the WEIMS in different work environments was evaluated. Second, its factorial structure and psychometric properties were assessed. Two samples of wo...

In this study, effects of multi walled carbon nanotubes and temperature on rheological behavior of engine oil (10W40) have been examined. For this purpose, the experiments were carried out in the temperature range of 5-55°C for several suspensions with solid volume fractions of 0.025%, 0.05%, 0.1%, 0.25%, 0.5% and 0.75%. The viscosity of all samples was measured in the shear rate range of 666s-...

The Analytic Hierarchy Process (AHP) is widely used method in multiple-attribute decision making. In the recent literature many authors used different judgment scales which influenced the results and decisions. In this paper the author reviews and discusses effects of utilization of various judgment scales on priority estimation in AHP. There has been studies that have been concerned with the c...

Introduction: The Questionnaire for Olfactory Dysfunction (QOD) is a self-reporting olfactory-related quality of life questionnaire. The aim of this study was to determine the reliability and validity of the Persian version of this questionnaire. Materials and Methods: One hundred and thirteen patients with olfactory problems were enrolled in this study. The English version of the QOD was first...

this study was aimed at evaluating the flow behavior characteristics of yogurt enriched with fish oil (fo) microcapsules prepared by complex coacervation method. fo was microencapsulated in gelatin-acacia gum coacervates. then, the microcapsules were dried, and yogurt was produced from the milk enriched with microcapsules powder. rheological characteristics (as measured using a rotational visco...

As information retrieval (IR) systems emerge as the mainstream information nding tool within commercial enterprises due to the enormous popularity of World Wide Web (WWW) technology in the intranet environments, the ability to incorporate new and/or updated documents into the database in real time becomes an essential requirement. However, conventional IR systems are optimized for read queries ...

Consistency is a qualitative measure of database performance. Consistency Index (CI) is a quantification of consistency of a data unit in terms of percentage of correct reads to the total reads observed on the data unit in given time. The consistency guarantee of a replicated database logically depends on the number of reads, updates, number of replicas, and workload distribution over time. The...

Background: The National Institutes of Health Stroke Scale (NIHSS) can objectively quantify the severity of stroke. However no information is available about psychometric properties and it’s applicability in the Iranian population. Objectives: The present study purposed by utilization of this instrument for neurological deficits measurement due to stroke, to determine the internal cons...
