in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
introruction khawf in(iran)-herat and mazaresharif and shirkhan bandar in (afghanistan)-dushanbe in (tajikistan)_(kirgizstan)-kashghar in(china) project railway network is under construction that it is as a significant corridor for revitalizing silk road corridor in the region .at the present there are three different gauge in the region central asia with 1,520 mm gauge and turkey-islamic repu...
today, persian poetry is of great importance to many scholars around the world. the interest and attention of various cultures toward such a fine literature has given quite a good motivation for a comparative study. the major concern of the study is to investigate how nature is depicted through the works of the great english poet, william wordsworth (1770-1850) and the outstanding contemporary ...
abstract global financial crisis has created too many problems in relations among governments. among these problems, the issue of global monetary management, more than every time in the past four decades, has been moved in the center of international economic attentions. a problem which is specially known with the monetary hostility between united states and public republic of china. where ar...
abstract the present thesis seeks to critically read george orwell’s nineteen eighty-four and animal farm in the light of louis althusser’s thought and theory. the present thesis proceeds to examine and demonstrate althusser’s major concepts including ideological state apparatuses (isas), repressive state apparatuses (rsas), the structure, the subject, and ideological interpellation which r...
The constant-time programming discipline is an effective countermeasure against timing attacks, which can lead to complete breaks of otherwise secure systems. However, adhering to constant-time programming is hard on its own, and extremely hard under additional efficiency and legacy constraints. This makes automated verification of constant-time code an essential component for building secure s...
As evermore applications are designed to run inside browsers and other JavaScript runtime systems, there is an increasing need for cryptographic primitives that can be used client-side. Unfortunately, implementing cryptographic primitives securely in high-level languages is extremely difficult—runtime system components such as garbage collectors and just-intime compilers can trivially introduce...
We generalize Cuckoo Hashing 23] to d-ary Cuckoo Hashing and show how this yields a simple hash table data structure that stores n elements in (1 +) n memory cells, for any constant > 0. Assuming uniform hashing, accessing or deleting table entries takes at most d = O(ln 1) probes and the expected amortized insertion time is constant. This is the rst dictionary that has worst case constant acce...
The constant speedup theorem, so well known from Tur-ing machine based complexity theory, is shown false for a natural imperative programming language I that manipulates tree-structured data. This relieves a tension between general programming practice, where linear factors are essential, and complexity theory, where linear time changes are traditionally regarded as trivial. Speciically, there ...
