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...
magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
In several senses, Hall cuts a better figure here than in Charlotte Hall's Memoirs. Nevertheless, the remnants of the earlier "spouseography" are often still visible, despite Manuel's apparent awareness of the historiographic implications of using Charlotte's work as a primary source (p. 23). Some instances are trivial. For example, Hall's trip to the Scottish Highlands is alluded to by Manuel ...
Galactosaemia was originally described by von Reuss in 1908 and since then a number of cases have been reported. From a study of these a fairly characteristic picture is presented, the most constant features being failure to thrive, hepatomegaly, galactosua and albuminuria. Other less constant features are mental retardation, jaundice, vomiting, cataract, pyrexia, diarrhoea and a tendency to bl...
The terms concreteness fading and progressive formalization have been used to describe instructional approaches to science and mathematics that use grounded representations to introduce concepts and later transition to more formal representations of the same concepts. There are both theoretical and empirical reasons to believe that such an approach may improve learning outcomes relative to inst...
Understanding the organic matter/organic carbon (OM/OC) ratio in ambient particulate matter (PM) is critical to achieve mass closure in routine PM measurements, to assess the sources of and the degree of chemical processing organic aerosol particles have undergone, and to relate ambient pollutant concentrations to health effects. Of particular interest is how the OM/OC ratio varies in the urban...
, we have shown that this method is appropriate for clustering face data when such a data set is taken from a number of individuals in a number of diierent poses. The network learns to create lters of the data set such that both the identity of the individual can be recognised and his/her pose also identiied. Future work will investigate larger data sets and diierent numbers of lters per person...
روشهای پانلی (panel method) از بین سایر روشهای محاسبه خصوصیات جریان سیال حول یک جسم، روشهای سریع، کارآمد و مناسبی هستندبر مبنای این روشها، نرم افزارهای متعددی نوشته شده اند که از میان آنها می توان به cmarc ، quadpan ، vsaero ، usaero و ... اشاره کرد. آنچه که در این تحقیق می آید محاسبه ضرایب آیرودینامیکی هواپیمای چهارنفره و تمام کامپوزیت فجر- 3 به کمک نرم افزار cmarc می باشد. پاسخهای به دست آمده...
در این تحقیق ابتدا با توجه به ویژگی های پدیده ی برخورد با سرعت بالا که عبارتند از تغییر شکل های بزرگ که منجر به یک مسئله ی غیر خطی هندسی و مادی میشود ، سطوح مادی در حال حرکت و سطوح آزاد ، مرزهای تغییر شکل پذیر و سیستم گسسته بر پایه ی قوانین محیط پیوسته، روشsph از میان روش های عددی انتخاب گردیده، سپس نحوه ی تخمین زدن متغیر میدان در این روش، روند فرمول نویسی sph و همچنین جایگاه این روش در میان رو...
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
