A two-way structure

When two-dimensional structure led the way.

A two-way road.

In 1991, Luka and ten of his comrades were captured near Knin, a Croatian town held by rebel Serbs and the Yugoslav Federal Army. Luka spent a few months in the Knin jail. The first days he was left without food or water. He kept refusing to submit himself to the guards, so they would often take him to the top floor and beat him until he would pass out. After-wards, they would drag him down, hi...

A Comparative Study of Metacognitive Strategies in One-way vs. Two-way Speaking Tasks among Iranian EFL Learners

This study was an attempt to investigate what metacognitive strategies are specifically employed by English learners when it comes to different speaking task types.60 students at advanced level (female) were randomly selected and given an OPT as a test of homogeneity. They were assigned to experimental and control groups. The MS questionnaire (Oxford, 1990) was also administered to see what MS ...

A Comparative Study of Metacognitive Strategies in One-way vs. Two-way Speaking Tasks among Iranian EFL Learners

This study was an attempt to investigate the effect of metacognitive strategies (MS) on speakingability of the learners and also what MS are specifically employed by learners when it comes todifferent task types. To this end, running a quasi-experimental study, 60 students at advancedlevel (female) from Shenia Language Institute in Sanandaj were randomly selected and given anOxford Placement Te...

Two-Way Two-Tape Automata

In this article we consider two-way two-tape (alternating) automata accepting pairs of words and we study some closure properties of this model. Our main result is that such alternating automata are not closed under complementation for non-unary alphabets. This improves a similar result of Kari and Moore for picture languages. We also show that these deterministic, non-deterministic and alterna...
