WELCOME ADDRESS
Dear Participants, Scientists, Colleagues,
On behaft of the President of The University of Science (HCMUS), Vietnam National
University - Ho Chi Minh City (VNU-HCMC) and the Organizing Committee, I have the
great honor to warmly welcome all of you to the HCMUS 8
th
Scientific Conference, to be
held on the 9
th
November 2012 at our Campus at 227 Nguyen Van Cu, district 5, Ho Chi
Minh city.
Carrying out scientific research is an essential activity of a highly qualified higher

education institution. During 70 years of foundation and growth of HCMUS, scientific
research has always been having an important role in the education mission of our university.
The efforts of our faculty, students together with their efficient collaborations with colleagues,
scientists of different education and/or research institutions in the country and abroad have
been always making our research activities effervescent, have produced excellent scientific
results, contributed to our established reputation as one leading center for basic scientific
education and research in Vietnam.
From the 7
th
Sientific Conference on 2010 up to now, during the two recent academic
years, HCMUS has been carrying out - 2010-2015 strategic plan
of development in science and technology (S&T) in order to assure the leading position of
the university in Vietnam in basic science and advanced S&Ts. Research groups of the
university have successfully received 230 research grants with a total amount of more than
25 billions VND including 06 core national grants in S&T, 1 international bilateral grant, 29
grants from Vietnam National Foundation for Science and Technology Development
(Nafosted), 28 core ministeral grants and others. Many excellent results have been achieved
and published: 126 international and 150 national publications, more than 200 full papers in
proceedings of national and international scientific conferences. Total value of technology
training and tranfer activities was more than 20 billions VND. HCMUS has signed
agreement on research and technology transfer with different domestic and international
partners such as Ho Chi Minh City Hitech Agriculture Park, IBM Vit Nam, Red Sun, HPT,
PINNACO, Research Center for Bird Conservation (Russia), Toyota Technological Institute
(Japan)
International collaboration has a particularly important role in research at our
university. During the two academic years, HCMUS has organized or co-organized more than
30 international workshops, symposiums, conferences. The university has hosted 94
international delegations, 30 visiting professors, international research fellows, students and
signed MOU for collaboration with 14 excellent universities, research institutes from different
countries.

Dear Participants, Scientists, Colleagues,
Since more than a decade, HCMUS has been organizing biannual scientific
conferences which covered all disciplines and fields of education and research at the
university. The objective of these scientific conferences is to provide the platform for authors
from our university and from collaborating institutions to present their research results in their


8
field of interests. On the other hand, the conference also aims to provide opportunity for
discussion, exchange of ideas and solutions to study integrated issues, which require the
engagement of different scientific fields, areas existing in the university, to stimulate the
collaboration and formation of interdisciplinary researches among research teams within the
university or with other institutions. The conference is also to provide opportunity for our
students to participate in scientific conference and to stimulate their passion for science and
doing science.
The Organizing committee of this 8
th
Scientific Conference has the great pleasure to
receive over 550 abstracts and full papers from 40 different institutions for education,
research and technology transfer in Vietnam and from abroad relating to many different
scientific and technological disciplines such as mathematics, computer science, physics,
chemistry, biology, geology, environmental science, materials science, oceanology,
information technology, biotechnology, environmental technology, electronics,
telecommunications. Through a preliminary evaluation and by suggestion of our scientific
sessions, we have selected 529 submitted papers to be present at the conference including 2
plenary presentations, 230 oral presentations at 9 parallel sessions and 297 poster
presentations. Among these, we are very pleased to welcome 8 international partitcipants from
3 distinguished universities from France, Belgium and Japan contributing 2 plenary and 8
session presentations. List of presentations with authors, institutions is included in this
Program Book. Abstracts of all presentations are edited into pdf files, which are attached as a

CD. From the conference result, excellent presentations will be selected for peer reviewing to
be published as scientific papres in the Journal of Science and Technology Development of
VNU-HCMC following the journal regulation. In addition, The Organizing committee also
evaluates and confers awards for excellent poster presentations.
We do hope the conference will provide all of you new and useful scientific ideas,
information, solutions, as well as to help you to successfully establish new relationships and
collaborations in education and research.
We would like express our sincere gratitude to all authors and their affiliated
institutions, particularly to our oversea participants, for their warmly supports and
participations, which have essentially contributed to the richness in scientific content of the
conference as well as to successfully achieve its scientific objectives.
Next, it is our honor to extend our acknowledgements of VNU-HCMC and HCMUS
for their support. We would also warmly thank all the sponsors who have contributed an
important part to cover the expenses of the conference. Our high appreciations and sincere
thanks are warmly extended to all leading scientists who chair the conference sessions, to
members of the conference and session organizing committees, to the university staff and
offices for their energetic efforts in the preparation of the conference.
I wish all of you good health, happiness and success.

EXISTENCE OF ASYMPTOTICALLY STABLE SOLUTIONS FOR
A VOLTERRA -HAMMERSTEIN INTEGRAL EQUATION

Abstract
The report is devoted to the study of a Volterra - Hammerstein integral equation. First, this equation is
reduced to a fixed point problem of a nonlinear integral operator and hence we can give suitable assumptions and
using a fixed point theorem of Krasnosel'skii type in order to obtain the existence of solutions. Next, we prove
the existence of asymptotically stable solutions for the above equation. In order to illustrate the results, an
example is also presented. This result is a relative generalization of [1]  [6].

EXISTENCE, BLOW-UP AND DECAY ESTIMATES FOR
A SYSTEM OF NONLINEAR WAVE EQUATIONS
ASSOCIATED WITH THE HELICAL FLOWS OF MAXWELL FLUID

Abstract
The report is devoted to the study of a system of nonlinear wave equations associated with the helical
flows of Maxwell fluid. First, based on Faedo-Galerkin method and standard arguments of density corresponding
to the regularity of initial conditions, we establish two local existence theorems of weak solutions. Next, we
prove that any weak solutions with negative initial energy will blow up in finite time. Finally, we give a
sufficient condition to guarantee the global existence and exponential decay of weak solutions via the
construction of a suitable Lyapunov functional. This result is a relative generalization of [1].

EXISTENCE AND DECAY ESTIMATES FOR A SYSTEM OF NONLINEAR WAVE
EQUATIONS WITH NONLINEAR BOUNDARY CONDITIONS
Abstract
The report is devoted to the study of a system of nonlinear wave equations with nonlinear boundary
conditions. First, based on Faedo-Galerkin method and standard arguments of density corresponding to the
regularity of initial conditions, we establish two global existence theorems of weak solutions. Next, the

exponential decay property of the global solution via the construction of a suitable Lyapunov functional is
presented.

NOTE ON A MULTI-POINT BOUNDARY VALUE PROBLEM
FOR A FOURTH-ORDER DIFFERENTIAL EQUATION
Abstract
The report studies several sufficient conditions for the existence of positive solutions for a multi-point
fourth order boundary value problem. Our main tools are the Guo-Krasnoselskii's fixed point theorem and the
monotone iterative technique.
