this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
چکیده مجموعه حاضر با هدف معرفی و ارائه ی توصیفی برای اصطلاحات رایج در دانش معنی شناسی تهیه شده است. برای دستیابی به چنین هدفی سعی بر آن بود تا صرفاً به واژگان نقش مند در شاخه ی عمده ی معنی شناسی زبانی توجه شود. در حوزه معنی شناسی زبانی، به اصطلاحات در شاخه ای از این دانش، یعنی معنی شناسی نظری (theoretical semantics) و آنچه معنی شناسی کاربردی (applied semantics) نامیده ایم، اشاره شود. و هدف از ت...
abstract the primary purpose of this study was to explore the actual practices and cognitions of two groups of iranian eap teachers, i.e. language teachers and content teachers, with respect to teaching reading-comprehension and vocabulary. to this end, tehran university of medical sciences which authorizes both groups of teachers to teach eap courses was selected as the context of the study s...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
The proposed method can be interpreted as a generalization of our previous method [1], which is the first algorithm that uses the sparsest k-subgraph problem for different-feature selection. Unlike the proposed method, the previous method has limited applicability due to the Gaussian assumption. In the previous method, we assumed Gaussian distributions on p and q, and defined the matrix L̂ by L̂d...
where P is a positive definite hermitian matrix and U is a unitary matrix. In this polar representation of the matrix A, as it is called, the two matrices P and U are unique. Since the matrix P is positive definite and nonsingular, it has the same signature as the identity matrix E while the unitary matrix U is a conjunctive automorph of E. From (1) we may deduce a somewhat similar representati...
Second-Order tuple generating dependencies (SO tgds) were introduced by Fagin et al. to capture the composition of simple schema mappings. Testing the equivalence of SO tgds would be important for applications like model management and mapping optimization. However, we prove the undecidability of the logical equivalence of SO tgds. Moreover, under weak additional assumptions, we also show the u...
