In this paper, automatic musical instrument identification using a variety of classifiers is addressed. Experiments are performed on a large set of recordings that stem from 20 instrument classes. Several features from general audio data classification applications as well as MPEG-7 descriptors are measured for 1000 recordings. Branch-and-bound feature selection is applied in order to select th...
background and objectives: questionnaire-based survey is the most common way of assessing patient satisfaction. however, most relevant survey instruments have been developed in western countries, and valid and reliable context-specific survey tools in this area are lacking. to help filling this gap, in this study we have developed and validated the preliminary version of the novel brief inpatie...
burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...
Surface It is likely that errors in the homogenized surface air temperature data do not contribute substantially to the large-scale differences between trends for different levels because these errors are very likely to be smaller than those for the upper air data. • Systematic local biases in surface trends may exist due to changes in station exposure or instrumentation over land, and due to t...
Objectives: Within the context of Health-Related Quality of Life studies, it was necessary to translate and evaluate the psychometric properties of the SF-12 Health Survey version 2. The aim of this study was to investigate the factorial structure, convergent validity and reliability of this instrument in a healthy Iranian sample, following translation and establishment of content and face vali...
Background: In modern world, attitudes of people are considered more important than their experiences and academic preparation. A positive attitude towards research is a key factor for success and progress in societies. Methods: This study was psychometric assessment with 141 faculty member from Iran university of medical sciences. Initial instrument with 10 –items was translated to Persian aft...
background: measuring content validity of instruments are important. this type of validity can help to ensure construct validity and give confidence to the readers and researchers about instruments. content validity refers to the degree that the instrument covers the content that it is supposed to measure. for content validity two judgments are necessary: the measurable extent of each item fo...
abstract: the present study was undertaken to investigate whether 1) there is any significant correlation between iranian efl/eap learners’ l2 writing proficiency and their willingness to communicate, 2) there is any significant difference between efl and eap learners in terms of willingness to communicate, 3) there is any significant difference in wtc of iranian efl/eap learners with 1- nati...
A method is proposed which enables one to produce musical compositions by using transposition in place of harmonic progression. A transposition scale is introduced to provide a set of intervals commensurate with the musical scale, such as chromatic or just intonation scales. A sequence of intervals selected from the transposition scale is used to shift instrument frequency at predefined times d...
