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...
15 صفحه اولinvestigation 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...
Histamine challenge testing: comparison of three methods.
Non-specific bronchial reactivity is related to the severity of clinical asthma. Histamine challenge testing is increasingly used in association with questionnaires in epidemiological studies of the prevalence and morbidity of asthma in the community. The histamine challenge method described by Cockcroft et al is widely used and well standardised but it has disadvantages for epidemiological stu...
متن کاملTheoretical evaluation and comparison of fast chemical shift imaging methods.
Magnetic resonance chemical shift imaging (CSI) is becoming the method of choice for localized NMR spectroscopic examinations, allowing simultaneous detection of NMR spectra from a large number of voxels. The main limitation of these methods is their long experimental duration. A number of fast CSI experiments have been presented, promising to reduce that duration. In this contribution the crit...
متن کاملAlgebraic multigrid and algebraic multilevel methods: a theoretical comparison
We consider algebraic methods of the two-level type for the iterative solution of large sparse linear systems. We assume that a ne/coarse partitioning and an algebraic interpolation have been de ned in one way or another, and review di erent schemes that may be built with these ingredients. This includes algebraic multigrid (AMG) schemes, two-level approximate block factorizations, and several ...
