The public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, includ...
Store-and-generate techniques encode a given test set and regenerate the original test set during the test with the help of a decoder. Previous research has shown that run-length coding, particularly alternating run-length coding, can provide high compression ratios for the test data. However, experimental data show that longer runlengths are distributed sparsely in the code space and often occ...
از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
in this paper we examine the effect of the oil volatility, consumer price index (cpi) and industrial production on the stock market return in tehran stock exchange (tse). we used seasonal data in period 1378-1390 and auto regressive distributed method (ardl) for the short-term and long-term relationship between the variables. as results of research indicate, we find that there is positive short...
We present a success story on the adoption of semantic technologies for the library of the second biggest university hospital of France. This project was divided into three parts: preprocessing, semantic enrichment and data integration. This abstract introduces the research challenges faced in the project as well as the outcomes obtained so far.
Since Sir Tim Berners-Lee announced the best practices to publish semantic data through the Web, Linked Data principles have been introduced into a wide variety of application domains. This usage of Linked Data eases the enrichment of offered data in a grade that the semantic data that not applies the Linked Data principles never would achieve. In this paper, we present LinkedQR, a tool to impr...
One of the most exciting scientific challenges in functional genomics concerns the discovery of biologically relevant patterns from gene expression data. For instance, it is extremely useful to provide putative synexpression groups or transcription modules to molecular biologists. We propose a methodology that has been proved useful in real cases. It is described as a prototypical KDD scenario ...
We developed a data-mining and visualization approach to analyze the mode-of-action (MOA) of a set of drugs. Starting from widegenome expression data following perturbations with different compounds in a reference data-set, our method realizes an euclidean embedding providing a map of MOAs in which drugs sharing the therapeutic application or a subset of molecular targets lies in close position...
The performance of a theorem prover crucially depends on the speed of the basic retrieval operations, such as finding terms that are unifiable with (instances of, or more general than) a given query term. In this paper a new indexing method is presented, which outperforms traditional methods such as path indexing, discrimination tree indexing and abstraction trees. Additionally, the new index n...
introduction: the fetus needs a considerable amount of cholesterol for the development of tissues and organs. studies have suggested that genetic and environmental factors influence the composition of cord blood lipoproteins. in this study, we aim to assess the effect of gestational age, sex and birth weight on the cord blood lipoproteins. methods: we collected umbilical cord blood samples fr...
