    Exploring Challenges of Differentiated Instruction in English Foreign Language Classroom by Muhammad Surya Rifqi

    Published 2024-06-01
    “…The study discovered that teachers faced challenges when organizing and delivering differentiated instruction, such as dealing with the selection of materials, methods, and assessments that match students' characteristics, teachers' intrinsic factors, a large number of students, time invested, and learning references. Participants offered suggestions to other teachers who want to use differentiated instruction by exploring more variations of learning activities, being open to technology, participating in various forms of professional development, recognizing the personalities of the students they teach, and spending more time preparing instruction so that student's learning needs are truly met. …”

    Joint beamforming for multiuser SCFDE block transmission system in frequency selective MIMO channels by Li-zhou Xu, Jian JIANG, Sheng DING, Ying-guan WANG

    Published 2013-03-01
    “…Single carrier frequency domain equalization (SCFDE) joint beamforming in frequency selective multiple input multiple output (MIMO) channels under the multi-user scenario was analyzed.Firstly,the frequency domain beamforming was transformed to a time domain filtering beamforming.By using the time domain model,the signal to interference plus noise(SINR)expression of every receiver at the decision point was shown after the frequency domain minimum mean square error(MMSE)equalization.Under a given quality of service(QoS)constraint of every receiver,the optimal beamforming coefficients minimizing the total transmitted power from all transmitters were found through solving a convex semidefinite programming (SDP) problem relaxed from a nonconvex quadratically constrained quadratic programming(QCQP)problem.Simulation demonstrates that the total transmitted power from all transmitters varies regularly with different settings deployed by the model.…”

    Anonymous security authentication scheme using elliptic curve cryptography and hash function in mobile network by Yuehui CHEN, Miao HUANG

    Published 2016-05-01
    “…In order to prevent personal data from being lacked and improve the existing mobile network roaming anonymous authentication scheme,anonymous security authentication scheme using elliptic curve cryptography and hash functions in mobile network was proposed.With elliptic curve cryptography and hash functions,random numbers were used to replace public key encryption and time stamp.Firstly,before using the roaming services of a foreign agent(FA),hash function was calculated.A host agent(HA)was used by mobile user to register.Then,authentication and session key were set up with elliptic curve encryption.If HA is always in FA,MU can update the session key with FA.Finally,through a common channel,MU could utilize HA to change their passwords.The analysis of the performance and safety shows that,compared with other similar programs,the proposed scheme has significantly improved efficiency and safety.And the virtual computing time is only 2.000 85 seconds,which sharply reduces the cost of computing.…”
