The Influence of Student Diversity on Applying Cooperative Learning in Ethiopian Polytechnic Colleges

open access: yesEducation Sciences, 2023
Cooperative learning is more effective in a well-managed classroom with diverse ethnic, linguistic, and religious backgrounds. To that end, this study examined the state of applications of cooperative learning and student diversity in polytechnic ...

Diversity through coded cooperation [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2006
Motivated by the recent works on the relay channel and cooperative diversity, this letter introduces coded cooperation, where cooperation is achieved through channel coding methods instead of a direct relay or repetition. Each codeword is partitioned into two subsets that are transmitted from the user's and partner's antennas, respectively.

Including Diversity Through Cooperation

open access: yesProcedia Computer Science, 2012
AbstractIn this article we describe the experience of several Portuguese Higher Education Institutions (HEI) that in the midst of a legislative void regarding the inclusion of students with special education's needs, try to work their way into the inclusion of those students through cooperation.We will focus on how that cooperation came into being, the

Amplify-and-Forward Relaying Based Spectrum Sharing in Both Time and Spectrum Domains With Wireless Powered Primary User

open access: yesIEEE Access, 2019
We propose a spectral and energy efficient cooperative spectrum sharing scheme with the primary user (PU) capable of harvesting wireless energy. Along with an access point (AP) transferring wireless power to PU, a secondary source (SS) and a secondary ...
