Key factors affecting on the success of ERP projects in Vietnam
Tạp chí Phát triển Khoa học và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 16 Số 2 - Trang 57-66 - 2013
Today, enterprise resource planning system (ERP) becomes popular and it is implemented in most business (in all fields and sizes) all over the world as well as in Vietnam. However, according to consultant experts, ERP projects, though on a large scale with high cost, entail low success rate. For Vietnamese contexts, those findings above are all the more true, because most of Vietnamese enterprises...... hiện toàn bộ
OPTIMAL STRIP LAYOUT OF IRREGULAR SHAPES CUTTING FROM RECTANGULAR SHEET
Tạp chí Phát triển Khoa học và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 13 Số 1 - Trang 39-48 - 2020
This article deals with optimal nesting problem when parts are cut from rectangular sheet in the footwear industry. The objective of the research is minimizing the waste of material or maximizing the number of parts to be cut from sheet materials. By generating the mathematical models and building up their algorithms, the software for solving problem dedicates to a number of industries for saving ...... hiện toàn bộ

On the performance of cooperative cognitive networks with selection combining and proactive relay selection
Tạp chí Phát triển Khoa học và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 18 Số 3 - Trang 29-38 - 2015
This paper proposes an outage analysis framework for cooperative cognitive networks with proactive relay selection and selection combining (SC) under licensed outage constraint, maximum transmit power constraint, independent non-identical (i.n.i) fading distributions, erroneous channel information, and licensed users’ interference. Towards this end, we firstly suggest power allocation for unlicens...... hiện toàn bộ
Application of the MQ RBF-FD method to calculating transient voltages of power transmission lines
Tạp chí Phát triển Khoa học và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 19 Số 2 - Trang 5-15 - 2016
This paper presents an application of the Radial Basis Function – Based Finite Difference Method (RBF-FD) to solving the electrical transient problems defined by the time-dependent ordinary differential equations. In this method, the finite difference approximations of first- and second-order derivatives in time domain are formalated the same as those in space domain based on the MQ (Multiquadrics...... hiện toàn bộ
APPLYING TURBO CODE TO THIRD GENERAL MOBILE SYSTEM IMT-2000
Tạp chí Phát triển Khoa học và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 4 Số 7 - Trang 11-22 - 2021
The third general mobile system (3G)'s purpose supports many kinds of services for everyone at anytime and anywhere. These include such as: high speed data transmission, figure data and multimedia service up to 2Mbps beside traditional voice service. With data rate up to 2Mbps, it is very necessary and important to enhance the transmission, line reliability in 3G. Channel coding is often used in d...... hiện toàn bộ
ENGLISH-MAJORED STUDENTS’ MOTIVATION IN ENGLISH LANGUAGE LEARNING AND THEIR USE OF READING STRATEGIES: RESEARCH PERSPECTIVES
Tạp chí Nghiên cứu nước ngoài - - 2021
Reading plays a vital role in improving second/foreign language learning as it can encourage the development of autonomous learners. Furthermore, ESL/EFL learners’ use of reading strategies can be affected by their learning motivation, which can result in the high or low frequent use of reading strategies in reading comprehension. The present study, therefore, investigated the motivation in Englis...... hiện toàn bộ

Experiments of absolute positioning using BEIDOU in Vietnam
Tạp chí Phát triển Khoa học và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 19 Số 2 - Trang 19-26 - 2016
We research on absolute positioning using Beidou pseudo-range measurements collected in Ho Chi Minh City. Positional accuracy achieved is 2.3m, 4.5m and 3.9m for the North, East and height components compared to (0.8, 0.9, 1.7) of GPS and (2.0, 1.9, 4.1) of GLONASS. This result shows that in Vietnam we can use only BEIDOU system for positioning and also opens the possibility of incorporating posit...... hiện toàn bộ
Automatic detection of sleep onset in healthy adults
Tạp chí Phát triển Khoa học và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 20 Số K3 - Trang 18-24 - 2017
Sleep is very important for the health. Analyzing the polysomnography (PSG) helps us get valuable information to assess the quality of sleep. In this work, we develop a program to automatically detect the transition from wakefulness to sleep in adults. The accurate detection of the point of sleep onset occurs in the first time is useful for assessing the micro-structure of sleep. The proposed meth...... hiện toàn bộ
