Optimization of process lability in logistics systems
Tạp chí Kỹ thuật và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 3 Số SI3 - Trang SI29-SI35 - 2020
The management and effective operation of enterprise systems – depending on
ever-changing environmental impacts – can only be achieved by an appropriate
information management practice. Today, in the corporate environment, an
astonishing amount of data (often unstructured) is generated. The efficient
processing of these data is by no means straightforward and unambiguous, and
thus presents signifi...
Development of air traffic control simulator system applied in education and training
Tạp chí Kỹ thuật và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 3 Số SI2 - Trang SI158-SI175 - 2020
This is a research and develop paper about air traffic control process at the
airport in national scientific research project. Air traffic control simulation
system has become familiar in developed countries. Moreover, in Vietnam, the
demand for air traffic control systems is increasing due to the boom of the
civil aviation industry in general and air navigation service providers in
particular. Ho...

Encapsulation of Gac oil in alginate bead by dripping method
Tạp chí Kỹ thuật và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 5 Số 1 - Trang 1392-1399 - 2022
Gac oil was encapsulated in the hydrogel bead using alginate as carrying
material by dripping method. Different parameters of all three stages of the
encapsulation process were investigated: alginate concentration (emulsification
stage), nozzle height, extruded pressure (bead formation stage) and calcium flow
rate (bead stabilisation stage). Gac oil emulsion was characterised through the
droplet’s...

Screening for in vitro inhibiting Nrf2 of some Vietnamese medicinal plants
Tạp chí Kỹ thuật và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 6 Số 3 - Trang In press - 2023
Nuclear factor erythroid 2–related factor 2 (Nrf2) is vital in regulating
cellular defenses against oxidative or environmental aggressors. Some studies
reveal that increasing Nrf2 activity affects chemotherapy drug resistance in
cancer; thus, Nrf2 has become an attractive target in cancer therapeutics
research. Our study screened the effects of 52 methanol extracts from different
parts of 24 medic...
Deformation behaviour of granular column reinforced by geosynthetic encasement
Tạp chí Kỹ thuật và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 4 Số 2 - Trang 948-954 - 2021
In Vietnam, the overpopulation and strong economic development require the
synchronous development of infrastructure such as roads, urban areas, industrial
parks, export processing zones, etc. With such requirements, the development of
land fund for infrastructure construction is an indispensable need. Meanwhile,
the appropriate land fund is very limited. Therefore, the land fund must be
developed...
Wind potential assessment and optimized turbine distribution in wind farm using WAsP and WindPRO software
Tạp chí Kỹ thuật và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 2 Số 3 - Trang 131-139 - 2020
In order to develop a wind farm project, the wind potential assessment and
siting wind turbine are very important. It directly impacts energy production –
a huge influence on the economic efficiency of the wind farm project. So, this
paper presents the method to assess wind potential and optimized turbine
distribution in Vietnam's offshore wind farm site, based on data from the met
mast of GIZ org...

A research on a new structure of forming tool in Single Point Incremental Forming (SPIF)
Tạp chí Kỹ thuật và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 3 Số SI1 - Trang SI157-SI163 - 2020
Single Point Incremental Forming (SPIF) is really a new technology of forming
metal sheet nowadays and in recent decades. Although it was invented in, 1967 by
Lezak, an American inventor, but the applications of the innovative technology
were broad from 1990 because of the advance of controlling technology. This
technology is especially adapted to small batch, unique or single productions.
There a...
Manufacturing Thermal-resistant Aluminum Alloy Wire for Overhead Line Conductor
Tạp chí Kỹ thuật và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 6 Số SI3 - Trang In press - 2023
One of the overhead line conductor’s tasks is to ensure high electrical
conductivity and high tensile strength after repeated heating to 180 oC.
However, conventional aluminum conductor steel reinforced (ACSR) does not meet
the above requirements (operating temperature ≤ 90 oC). To solve this problem,
foreign countries have used Zr-bearing aluminum alloy, adding other alloying
elements, such as Si...

Head injury of Vietnamese pedestrian in crash accident with SUV using numerical simulation
Tạp chí Kỹ thuật và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 3 Số SI2 - Trang SI129-SI144 - 2020
Crash test simulation using finite-element method is more and more popular in
the automobile industry because of its feasibility and cost saving. The majority
of finite element dummy models used in crash simulation are built based on
anthropometrical and biomechanical data of the USA and European bodies. Thus, it
is necessary to develop a scaling algorithm to scale a reference dummy size into
a de...

Effect of marble powder content on compressive strength and water absorption of high-strength concrete
Tạp chí Kỹ thuật và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 5 Số 3 - Trang 1633-1641 - 2022
This paper presents the effect of marble powder content on compressive strength
and water absorption of high-strength concrete to expand the utilization of such
waste in the construction industry and to reduce the Portland cement production
which negatively affects the environment. Mixture proportion of reference
concrete without marble powder was designed as per TCVN 10306:2014 with a
designed co...
