Comparability of Multiple Rank Order and Paired Comparison Methods

on the comparison of keyword and semantic-context methods of learning new vocabulary meaning

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...

investigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances

در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...

Optimal Scaling of Paired Comparison and Rank Order Data: an Alternative to Guttman’s Formulation

A formulation, which is different from Guttman’s is presented. The two formulations are both called the optimal scaling approach, and are proven to provide identical scale values. The proposed formulation has at least two advantages over Guttman’s. Namely, (i) the former serves to clarify close relations of the optimal scaling approach to those of Slater and the vector model of preferential cho...

Eye Tracking Observers During Rank Order, Paired Comparison, and Graphical Rating Tasks

In studying image quality and image preference it is necessary to collect psychophysical data. A variety of methods are used to arrive at interval scale values which indicate the relative quality of images within a sample set. The choice of psychophysical technique is based on a number of criteria, including the confusion of the sample set, the number of samples to be used, and attempts to mini...
