THE MILITARY IN VIETNAM'S FEUDAL SOCIETY: A STUDY OF THE LOCAL MILITIA UNDER THE NGUYỄN DYNASTY’S POLICY OF "LODGING SOLDIERS AMONG FARMERS" (1802-1885)
No full textThis paper focuses on clarifying the role of local militia, a crucial force in the policy of “lodging soldiers among farmers” under the Nguyen Dynasty. To elucidate this issue, the author employs two primary research methods
in history: historical and logical approaches. The historical method aids in reconstructing the historical picture as objectively as possible, while the logical method facilitates the author in making assessments and evaluations of
the objective laws governing the research problem. The research materials used by the author are valuable primary sources from the Nguyen Dynasty that have been preserved to this day. Additionally, the author leverages the research of other scholars to clarify the raised issues. Through this, the paper will clarify specific issues as follows: First, the author will provide a general overview of the local militia under the Nguyen Dynasty; Second, the paper will elucidate the contributions of the local militia under the Nguyen Dynasty; Third, the paper
will evaluate the role of the local militia in the “lodging soldiers among farmers” policy of the Nguyen Dynasty (1802-1885). The results of this study will serve as a valuable source for clarifying the human resource management of the Nguyen feudal dynasty (1802-1885). Moreover, it is essential material for those interested
in this subject
Towards A New Tensegrity System: for Large-span Structures
No full textThroughout the long history of architecture, the effect of gravity is always present in any structures. Surprisingly in tensegrity composition, this primary law of nature seems to be absent. This is because the discontinuous set of struts in the continuous network of proportionally thin cables makes the structures look like floating in the air. However, there has not been much application of tensegrity principle in the construction field due to the lack of design methods and its complexity. By developing a large-span structure using tensegrity systems, a design method and an analysis technique are introduced along to define double-surface tensegrity systems. The design approach explores an innovative way to determine the structural topology and geometry of such the systems. The form-finding process and structural analysis are conducted to discover an appropriate way of analyzing tensegrity and ensuring that the systems are stable.Architecture, Urbanism and Building Sciences | Building Technolog
Morphological and molecular characteristics of Kudoa scomberomori (Myxosporea: Kudoidae) firstly foundfrom the muscles of info-pacific king mackerel Scomberomorus guttatus in Quang Binh province, Vietnam
No full textThe genus Kudoa includes about 100 described species. In Vietnam, so far, only one species, Kudoa monodactyli, has been reported. During servey for parasites of marine fish in Quang Binh province, Vietnam in 2017, we found Myxozoan samples in 8 out of 15 Indo-Pacific king mackerel (Scomberomorus guttatus). They are identified as K. scomberomori based on the results of morphological and molecular analyses. A great number of individual spores form white pseudocysts with thin membrane within the muscle fibre. The pseudocysts were 0.1-0.3 × 0.4-0.7 mm. The shape of fresh spore like a flower petal. The spore of K. scomberomori was 6.65 ± 0.09 (6.53-6.76) µm in length, 7.42 ± 0.13 (7.29-7.58) µm in width and 6.55 ± 0.11 (6.40-6.65) µm in thickness. Each spore has six shell valves with same size. Each shell valve contained one polar capsule measuring 3.42 ± 0.09 (3.32-3.48) µm in length and 1.30 ± 0.14 (1.14-1.46) µm in width. This is the first report of K. scomberomori in Vietnam and Indo-Pacific king mackerel is recorded as a new host for this species.

Geometrically nonlinear dynamic response and vibration of shear deformable eccentrically stiffened functionally graded material cylindrical panels subjected to thermal, mechanical, and blast loads
No full text Based on the first order shear deformation shell theory, this paper presents an analysis of the nonlinear dynamic response and vibration of imperfect eccentrically stiffened functionally graded material (ES-FGM) cylindrical panels subjected to mechanical, thermal, and blast loads resting on elastic foundations. The material properties are assumed to be temperature-dependent and graded in the thickness direction according to simple power-law distribution in terms of the volume fractions of the constituents. Both functionally graded material cylindrical panels and stiffeners having temperature-dependent properties are deformed under temperature, simultaneously. Numerical results for the dynamic response of the imperfect ES-FGM cylindrical panels with two cases of boundary conditions are obtained by the Galerkin method and fourth-order Runge–Kutta method. The results show the effects of geometrical parameters, material properties, imperfections, mechanical and blast loads, temperature, elastic foundations and boundary conditions on the nonlinear dynamic response of the imperfect ES-FGM cylindrical panels. The obtained numerical results are validated by comparing with other results reported in the open literature. </jats:p
Creating agents as artificial computer users
No full textThis project is concerning with creating agent as artificial computer user. The author has successfully implemented a FALCON agent that can learn from human activity patterns and can perform it own activities like an artificial computer user. The result is in the form of a log that records all activities performed in one whole day.
Activities performed by human user will be recorded and used as training data to train the agent. In order to support the training, pre-processing of data is needed.
The agent has been tested and been proved that more than half of its result can deceive human judges. The user interface allows the user to monitor the training and execution of the agent. The users can choose to perform automatically and receive the result or they can choose to go through the performing step by step and to monitor the changing in the states of the agent.Bachelor of Engineering (Computer Science

Uniaxially oriented nickel aluminum superalloy films sputtered with in situ heating
No full textWe report uniaxially oriented nickel aluminum (NiAl) films grown by DC magnetron sputtering under in situ heating. The films self-organize in (110) orientation with relatively low surface roughness and tight grain boundaries in columnar structure. The electrical carrier concentration and resistivity are on the order of 10(21) cm(-3) and 10(-5) omega center dot cm, respectively. The plasmonic performance, as indicated by the dielectric function, is comparable to that of a NiAl single crystal and exceeds those of conventional refractory materials (molybdenum, tungsten, titanium nitride) at visible to NIR wavelengths. This work paves the way to superalloy-based plasmonic nanostructures for photothermal energy applications
Free vibration analysis of FGM stepped nanostructures using nonlocal dynamic stiffness model
No full textA nonlocal Dynamic Stiffness Model (DSM) for free vibration analysis of Functionally Graded Material (FGM) stepped nanostructures based on the Nonlocal Elastic Theory (NET) is proposed. An exact solution to the equation of motion of a nanobeam element according to the Timoshenko beam theory, NET, and taking into account position of the neutral axis is constructed. Nondimensional frequencies and mode shapes of complete FGM stepped nanostructures are easily obtained using the nonlocal DSM. Numerical results are presented to show significance of the material distribution profile, nonlocal effect, and boundary conditions on free vibration of nanostructures
