Bài báo này nghiên cứu và đề xuất một hướng tiếp cận trong việc chuyển đổi dữ liệu từ dạng cơ sở dữ liệu quan hệ (RDB) sang Ontology được biểu diễn bằng các ngôn ngữ RDF và OWL. Quá trình chuyển đổi bao gồm 2 bước chính: (i) Ánh xạ lược đồ (tạo ra các lớp từ các bảng, tạo ra các thuộc tính đối tượng (object property) từ các khóa ngoại và tạo ra thuộc tính kiểu dữ liệu (datatype property) từ các thuộc tính không tham gia vào khóa ngoại), (ii) Ánh xạ dữ liệu (tạo ra các thể hiện).

In this paper, we present a definition of fuzzy multivalued dependencies in fuzzy databases with linguistic data based on similarity relation which is built by partitioning the domain of attribute values corresponding to an appropriate hedge algebra. Some properties of fuzzy multivalued dependencies are studied. Finally, the set of inference rules is shown to be sound and complete for a relation scheme class when it satisfies some specified conditions.

The aim of this paper is to present the concepts about Type 2 Approximate Functional Dependency - AFD 2 (relating to the correlation between atributes of the relational file) and the outliers with functional dependency. The paper also gives some properties of ADF 2 and algorithms for finding the outliers with functional dependency.

In the last decades, there have been some extensions of fuzzy sets and their applications. Recently, type-2 fuzzy set and intuitionistic fuzzy set are two of them, drawing a great deal of scientist's attention because of their widespread range of applications. In this paper, we introduce a new concept - type-2 intuitionistic fuzzy set and propose some properties of their operations.

The study on the relationship between technological parameters and mechanical properties of the blends has been carried out. According to the obtained results, the suitable conditions to prepare rubber powder for the following blending step were established. The thermoplastic elastomeric blend based on poly(vinyl chloride) (PVC) and vulcanized butadiene-acrylonitrile rubber (NBR) containing dioctylphtalate (DOP) processes good mechanical properties.

The study on the relationship between compositions and mechanical properties of the blends based on poly(vinyl chloride) (PVC), butadiene-acrylonitrile rubber (NBR) and natural rubber (NR) has been carried out. The result shows that in the presence of NBR, which plays role of transition phase between the two incompatible polymers PVC and NR, the tertiary phase polymer blends having high tensile strength and elongation at break were obtained.

Epoxy-cardanol nanocomposites were prepared by insitu polymerization techniques. Their structures and properties were investigated by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The results showed that the chains of epoxy-cardanol resin could be intercalated into the galleries of nanoclay I.30E to form exfoliated structure. The influence of nanoclay I.30E on the thermal of epoxy-cardanol resin was determined by TGA method, which showed an increase with increasing amounts of nanoclay I.30E.

In this work short bamboo fibre with dimensions 250µm was used to commute part of glass fibre to reinforce Bulk Molding Compound (BMC) materials based on unsaturated polyester. It was found that the physico-mechanical properties of this material with weight ratio short bambo/glass fibres 34/66 as good as of glass fibre reinforced BMC material of IDI Industrial Dielectrics Inc., USA.

In this paper, nickel oxide thin films on the titanium substrate were prepared by the sol-gel dipcoating technique with the precursors NiSO4.7H2O and acetic acid. The obtained thin films have a good adhesion to the substrate. The electrochemical behaviors of the NiOxHy thin films were investigated in KOH 1 M solution by the voltammetry technique. The effect of addition of platinum, heating temperature and the dip coating number on the electrochemical behavior was also investigated. The thin films have high electrochemical properties at 270o C and at third dip coating.

The HN-06 compound was found as compatibilizer for natural rubber (NR)-chloroprene rubber (CR) blend. The blend containing 0.8 wt% HN-06 compound gave good compatibility and it can be observed by scanning electron microscopy (SEM) image of two rubbers layer’s interface. Blend of NR/CR/HN-06 = 70/30/0.8 wt% have high mechanical properties the tensile strength 25.1 MPa, the tear strength 43.1 N/mm, the abrasion loss 0.044 g, good ozone and oil resistance.

The preparation and mechanical properties of bamboo - glass fiber mat reinforced polyropylene hybrid composite (BGMRPC) were investigated. The results showed that properies of the composite depend on the amount of glass fiber mat and the hybrid method. Replacing 13.5% of bamboo fiber mat by glass fiber mat, the tensile, flexural and impact strengths of BGMRPC were increased by 33%, 28% and 79% respectively comparing to bamboo fiber mat reinforced polypropylene composite (BMRPC). The moisture absorption of BMRPC and BGMRPC was studied and compared.

This paper present the results of research on designing mold for vacuum infusion technique for preparation the polymer composite material. Specimens of varrious methods of vacuum technique have been prepared and their mechanical and structural properties have been studied. The results show that material obtained from vacuum assisted technique have a preciously mechanical properties, increased in average 45% in comparison with hand lay up method. The scanning electronic microscopy has been used for investigation on void appearance of composite materials.
