Tập 24 - Trang 82-87 - 2020
Vu Xuan Thang, Nguyen Dinh Chien, Pham Ngoc Hung, Nguyen Thu Ha, Trinh Van Loan
Many factors affect speech recognition including dialect factors. Vietnamese is
a tone language with many different dialects. Therefore, spoken Vietnamese
identification is also significantly influenced by dialect. If the information
about dialects is known during the speech recognition process, the performance
of recognition systems will be better because the corpus of these systems is
normally o... hiện toàn bộ

Influence of composition, doping concentration and annealing temperatures on optical properties of Eu3+-doped ZnO-SiO2 nanocomposites
Tập 9 - Trang 69-72 - 2016
Le Thi Thu Hien , Nguyen Duc Chien , Pham Son Tung , Tran Ngoc Khiem
We have stupied structure and optical properties of ZnO - SiO2 nanocomposites
doped with Eu3+ ions with varied concentrations of ZnO and the annealing
temperatures. The thin films containing ZnO - SiO2 nanocomposites doped Eu3+
ions were preparedby sol – gel method and spin-coating process. The stuctures
and morphologies of the thin films are studied by X- ray diffraction ( XDR) and

IMPLEMENTATION OF BLACK HOLE ATTACK ON AODV ROUTING PROTOCOLS IN MANET USING NS2
Tập 25 - Trang 45-51 - 2020
Le Trung Hieu, Nguyen Duy Tan, Luu Van Tan
One of the major challenges of Mobile Ad hoc Network (MANETs) is how to
implement and avoid of different kind of security attack such as Denial of
service (DoS), wormhole, replay, masquerade, black hole etc. MANETs use routing
protocol to communicate the data packet from one node to another and each node
acts as a host or router, which can choose suitable paths for transmission of
packet. AODV is ... hiện toàn bộ

REFLECTIONS ON USING SOME COMMUNICATIVE ACTIVITIES IN TEACHING ENGLISH GRAMMAR
Tập 13 - Trang 79-82 - 2017
Nguyen Thi Thu Thuy
Grammar is undoubtedly part of a language. Therefore, teaching and learning
English grammaris indispensable to teaching and learning English. Poor English
grammar will definitely make learners fail to communicate effectively in
English. However, English grammar will only help if it is communicatively
taught. That is to say, teachers should introduce English grammar in contexts
and create practice ... hiện toàn bộ

SIMULATION AND EVALUATION ABOUT MAC PROTOCOLS IN WIRELESS SENSOR NETWORK USING NS2
Tập 23 - Trang 39-45 - 2019
Vu Thi Thu Huong, Nguyen Duy Tan, Nguyen Thi Thanh Hue
One of the major challenges of wireless sensor networks (WSN) is how to utilize
efficiently battery energy resource to extend the lifetime of the entire network
because of power constrained devices. Many MAC (Medium Access Control) protocols
have been taken to decrease the energy consumption of sensor nodes such as IEEE
802.11, 802.15.4 MAC or sensor MAC (S-MAC) protocols. In this paper, we provid... hiện toàn bộ
