A. For f , g ∈ ω let c∀f ,g be the minimal number of uniform g-splitting trees needed to cover the uniform f -splitting tree, i.e., for every branch ν of the f -tree, one of the g-trees contains ν. Let c∃f ,g be the dual notion: For every branch ν, one of the g-trees guesses ν(m) infinitely often. We show that it is consistent that c∃fǫ ,gǫ = c ∀ fǫ ,gǫ = κǫ for continuum many pairwise d...
If a configuration of m triangles in the plane has only n points as vertices, then there must be a set of max { dm/(2n− 5)e Ω(m3/(n6 log n)) triangles having a common intersection. As a consequence the number of halving planes for a three-dimensional point set is O(n log n). For all m and n there exist configurations of triangles in which the largest common intersection involves max {dm/(2n− 5)...
abstract: sayyed mohammad tabatabaee is accounted as one of the effective persons in iran contemporaneoushistory and his role in the events of iran constitution revolution is inevitable. sayyed mohammad tabatabaee from the time of naser al din shah qajar and arrival to iran, informed of the advantages and the basis of constitution, was in the thought of making the iran rule as a constituti...
We show that the number of halving sets of a set of n points in R is O ( n ) , improving the previous bound of [9] with a simpler (albeit similar) proof.
We show, with an elementary proof, that the number of halving simplices in a set of n points in R4 in general position is O(n4−2/45). This improves the previous bound of O(n4−1/13 4 ). Our main new ingredient is a bound on the maximum number of halving simplices intersecting a fixed 2-plane.
A. For f > g ∈ ω let c∀f ,g be the minimal number of uniform trees with g-splitting needed to ∀-cover the uniform tree with f -splitting. c∃f ,g is the dual notion for the ∃ cover. Assuming CH and given א1 many (sufficiently different) pairs ( f2 , g2 ) and cardinals κ2 such that κ0 2 = κ2 , we construct a partial order forcing that c∃f2 ,g2 = c ∀ f2 ,g2 = κ2 . For this, we introduce a c...
abstract this study aimed at investigating the translation of interjections from english into persian in dubbing. to carry out this study the expressive secondary interjections found in the film four weddings and a funeral and their equivalent in persian dubbed version were analyzed through the strategies proposed by cuenca. the descriptive analysis of the corpus showed that (strategy b) i.e...
abstract the main purpose of this study was to investigate whether there was any significant difference between the speaking achievement of learners who were trained by means of consciousness raising of sociolinguistic skills and that of learners who were trained without the above mentioned task. the participants of this study consist of 60 intermediate level students participating languag...
the purpose of the present study was to investigate the effect of task-based instruction of vocabulary on the receptive and oral productive acquisition of english vocabulary and compare the results with those obtained from the traditional method. the method and procedure applied in this study was as follows: after the implementation of opt, a group of sixty female students were chosen. the stu...
We study divisor class halving for hyperelliptic curves of genus 2 over binary fields. We present explicit halving formulas for the most interesting curves (from a cryptographic perspective), as well as all other curves whose group order is not divisible by 4. Each type of curve is characterized by the degree and factorization form of the polynomial h(x) in the curve equation. For each of these...
