For any integer N ^ 3 we will construct a 3-manifold which can be described as +1 surgery on N distinct knots in S. We will also give examples of 3-manifolds which are i^-fold cyclic branched covers of S over 2 distinct knots. Brakes (2) discovered the first examples of 3-manifolds with multiple knot surgery descriptions. Our construction is much different and follows directly from the construc...

Game-based practicing of materials can be seen as a method of capturing an essence of real- life expe-rience which is commonly missing in the conventional face-to-face classrooms. To serve the L2 learn-ers'' immediate communicative needs in wider classroom and societal contexts, this study sought to place L2 English learners within an interactional social framework through reinforcing their Eng...

This paper describes the use of a rule based system for generation of pronunciation variants as a component of a speech-enabled computer aided pronunciation learning (CAPL) system. This CAPL system is a part of a computer aided recitation of the holy Qur an training system. It generates the most probable pronunciation error hypotheses that are fed to a hidden Markov model (HMM)-based speech rec...
