HAI PHONG TOURISM – THE CURRENT SITUATION AND ISSUES

Tourism has been identified by the Party and State to develop into a spearhead economic sector of the country. Hai Phong city converges favorable conditions for tourism development such as diverse tourism resources, and relatively synchronous infrastructure. During the integration period, Hai Phong tourism has achieved many remarkable results, but not commensurate with the potential and advantages of the city. From the practice of developing tourism business activities in the city in recent years, the view and orientation of developing tourism to become a spearhead economic sector, one of the three pillars of socio-economic development of the city are posing problems for Hai Phong's tourism to solve.  Article visualizations

On a nonlinear heat equation associated with Dirichlet -- Robin conditions

This paper is devoted to the study of a nonlinear heat equation associated with Dirichlet-Robin conditions. At first, we use the Faedo -- Galerkin and the compactness method to prove existence and uniqueness results. Next, we consider the properties of solutions. We obtain that if the initial condition is bounded then so is the solution and we also get asymptotic behavior of solutions as. Finally, we give numerical resultsComment: 20 page

An evaluation of economic viability of small scale slaughterhouses in Vietnam: Implication for pig value chain development

Slaughterhouse plays important role in pig value chain in Vietnam, not only for the functions it plays and economic added value it generates, but also for product quality relates to food safety standards that is much affected under slaughtering activity. The study is aimed to get a better understanding of structure, conduct, performance and economic viability of small scale slaughter houses in the pig value chain, and draw key implications for pig value chain development in Vietnam. Nghe An and Hung Yen are selected as study site. Data is collected from 51 small scale slaughterhouses in 18 communes. Descriptive and comparative statistics are employed with t-test for mean comparison. Results show that slaughterhouse plays multiple functions in the pig value chain, generate permanent jobs for at least 2 family labors, and provides an income of about 18 USD/working day for family labor, contributing about threefourths of total family income. Slaughtering activity generates an added value of 165 USD/one ton of live pig, accounting from 24%-44% total value added in the pig value chain. Upstream and downstream linkages of slaughterhouses in the chain are quite loose with no formal contract. The majority of small scale slaughterhouses do not meet the standards for pig slaughterhouse as required by the Ministry of Agriculture and Rural Development. The setting up as well as slaughtering practices are perceived to contribute to exposure of meat to contamination that could lead to higher incidence of salmonella in pork, a common cause of foodborne illness for consumers. Rising concerns of consumers about food safety as well as increasing level of economic integration of Vietnam are factors potentially having great impacts on economic viability of small scale slaughterhouse in Vietnam. Several recommendations for upgrading slaughterhouse are proposed accordingly

An experimental study and a proposed theoretical solution for the prediction of the ductile/brittle failure modes of reinforced concrete beams strengthened with external steel plates

An experimental study and a proposed theoretical solution are conducted in the present study to investigate the ductile/brittle failure mode of reinforced concrete beams strengthened with an external steel plate. The present experimental study has fabricated and tested six steel plate-strengthened RC beams and one non-strengthened RC beam under 4-point bending loads. The proposed theoretical model is then developed based on the observed experimental results to analyze the crack formation, to determine the distance between vertical cracks and to quantitatively predict the ductile/brittle failure mode of plate-strengthened RC beams. The experimental study shows that the failure mode is based on the sliding of concrete along with the external plate. This slip is limited between two vertical cracks, from which the maximum stress in the external steel is determined. Based on comparisons conducted in the present study, excellent agreements of the stresses/strains in soffit steel plates, crack distances, and system failure modes between the current theoretical solution and the previous and present experimental results are observed.&nbsp

Position control for haptic device based on discrete-time proportional integral derivative controller

Haptic devices had known as advanced technology with the goal is creating the experiences of touch by applying forces and motions to the operator based on force feedback. Especially in unmanned aerial vehicle (UAV) applications, the position of the end-effector Falcon haptic sets the velocity command for the UAV. And the operator can feel the experience vibration of the vehicle as to the acceleration or collision with other objects through a forces feedback to the haptic device. In some emergency cases, the haptic can report to the user the dangerous situation of the UAV by changing the position of the end-effector which is be obtained by changing the angle of the motor using the inverse kinematic equation. But this solution may not accurate due to the disturbance of the system. Therefore, we proposed a position controller for the haptic based on a discrete-time proportional integral derivative (PID) controller. A Novint Falcon haptic is used to demonstrate our proposal. From hardware parameters, a Jacobian matrix is calculated, which combines with the force output from the PID controller to make the torque for the motors of the haptic. The experiment was shown that the PID has high accuracy and a small error position

ZnO/CdS Bilayer used for Electrode in Photovoltaic Device

In this article we present the fabrication and characterization of the nanoporous ZnO and/or ZnO/CdS thin films onto indium doped-tin oxide (ITO) substrates, based on the thermal evaporation technique followed by thermal treatment. The preparation method was relatively simple and low-cost for large scale uniform coating to produce clean, dense and strong adhesion to substrate thin films. The nanostructured ZnO and ZnO/CdS thin films were characterized by X-ray diffraction (XRD) and field emission scanning electron microscope (FE-SEM). The nanostructured ZnO/CdS bilayer film was used in a photo-electrochemical (PEC) cell as a working electrode and a Pt net as a counter electrode. The results show that the photovoltaic cell with nanostructured ZnO/CdS bilayer film electrode has significantly improved photoelectric capability in comparison with that of ZnO electrode

Impacts of remittances on foreign direct investment in South East Asia - An empirical investigation

This study investigates the effects of remittances on attracting foreign direct investment flows to South East Asia. Using a balanced panel data set for seven countries in the 2000-2013 period, we find that remittances have a direct positive impact on attracting FDI. Significantly, the result also shows a negative correlation between remittances and FDI attraction in countries with low per capita income and small market size
