students perception of computerized toefl test

تحقیق حاضر به بررسی درک دانشجویان از مزایا و معایب آزمون های کامپیوتری تافل و تاثیر جنسیت بر درک آنها پرداخته است. شرکت کنندگان در این تحقیق 100 نفرزبان آموز مرد و زن بودند که در آزمون کامپیوتری تافل در ایران شرکت کرده بودند. پرسشنامه یی که در مورد مزایا و معایب آزمون های کامپیوتری در مقایسه با آزمون های کاغذی توسط محقق تهیه شده بود جهت تکمیل به این افراد ارایه شد. داده های بدست آمده در این مطا...

ALVEY lexicon OFF - LINE PROCESSING : ON - LINE PROCESSING

Feasibility and Unfeasibility of Off-Line Processing

We formally investigate the idea of processing off-line part of the input data in order to speed up on-line computing. In particular, we focus on off-line processing for intractable decision problems. To this end, we define new complexity classes and reductions, and find complete problems.

Effect of NOCOLOK® flux dry-off temperature on brazed joint strength of aluminum-based heat exchangers

During the brazing of aluminum-based heat exchangers, the flux dry-off temperature plays a crucial role to get sound joints with maximum strength. In the present study, the NOCOLOK® flux consists of two phases of K2AlF5.H2O and KAlF4 with a melting point around 580 °C was used for brazing AA3003 as base metal with a clad-coating of AA4343 as filler metal. The slurry was applied on the joints an...
