Stability of individual loudness functions obtained by magnitude estimation and production

Measuring Loudness of Long and Short Tones Using Magnitude Estimation

McFadden (1975) questioned the accuracy and reliability of the method of magnitude estimation for the measurement of loudness of tones that vary both in duration and level. He suggested that it produced unreliable results and should not be used to assess how loudness depends on stimulus duration. To examine this issue further, the present study obtained loudness functions for 5and 200-ms tones ...

extremal region detection guided by maxima of gradient magnitude

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...

Estimation of Production Functions

1 Introduction Why do we care about estimating production functions (in an IO course)? Production functions are components in many economic models; Evaluate e¢ ciency of an industry: – increasing returns, economies of scale – complementarity / substitutability between inputs – cost regulation, synergies and mergers – economics of scope – learning by doing Productivity analysis (output per index...

the relationship between individual versus pair writing tasks and levels of fluency, complexity and accuracy in efl writing by iranian learners

پژوهش کنونی با هدف مطالعه رابطه بین نوشتار بصورت انفرادی و گروهی با میزان دقت، پیچیدگی و سلاست دانش آموزان زبان انگلیسی حین نگارش متون انجام شده است. بمنظور دستیابی به این هدف، دو گروه از دانش آموزان مقطع متوسطه موسسه زبان کیش انتخاب شده و سپس از آنها خواسته شد تا 6 متن را با 6 موضوع متفاوت و طی 6 جلسه به نگارش در آورند. تجزیه و تحلیل این پژوهش با هدف اندازه گیری میزان دقت، پیچیدگی و سلاست نوشت...
