CoxPt100- x nanoparticles (x=50, 59, and 73) were prepared by the chemical reduction of Cobalt (II) chloride and Chloroplatinic acid, then ultrasonicated for 2 h. After annealing at various temperatures from 450 C to 700 C for 1 h, structure change was observed and samples show hard magnetic prop-erties which depend strongly on chemical composition and annealing temperature. The highest coer-civity value of 1.15 kOe was obtained at room temperature for sample with x =50 annealed at 500 C. Chemical reduction combined with ultrasound is a useful method to prepare CoPt nanoparticles

Using the Directional Analytic Signals of Magnetic Gradient Tensor to Determine Boundaries of Source

Nguyen, Thi Thu Hang Pham, Thanh Luan Do, Duc Thanh Le, Huy Minh The analytic signals of the magnetic tensor gradient within two-and three-dimensional space can be applied as a useful tool to estimate the depth and position sources because its value characteristics only depend on location but magnetization direction of the sources of the magnetic anomaly [7]. In this paper, we present results of the study for application of the combination of derivatives of directional analytic signals of the magnetic tensor gradient to determine the edges of the sources through the new function Edge-detector (|ED|). Algorithms and programs written in the Matlab language have been used for test calculation on 3D models in correlative comparison with the method using the amplitude function of analytic signals ([2]). The calculation results showed the advantages of the new function |ED| and its applicability in determing the boundaries of sources of magnetic anomaly. Chi tiết xin mời th...

The Determinants of Capital Adequacy Ratio: The Case of the Vietnamese Banking System in the Period 2011-2015

Pham, Thi Xuan Thoa Nguyen, Ngoc Anh The analysis of a data set of observations for Vietnamese banks in the period 2011-2015 shows how the Capital Adequacy Ratio (CAR) is influenced by selected factors, namely: asset of the bank SIZE, loans in total assets LOA, leverage LEV, net interest margin NIM, loans lost reserve LLR, Cash and Precious Metals in total assets LIQ. Results indicate, based on data, that NIM and LIQ have significant effect on CAR. On the other hand, SIZE and LEV do not appear to have significant effect on CAR. Variables NIM, LIQ have positive effect on CAR, while variables LLR and LOA are negatively related with CAR Chi tiết xin mời tham khảo tại http://repository.vnu.edu.vn/handle/VNU_123/56299 Title:  The Determinants of Capital Adequacy Ratio: The Case of the Vietnamese Banking System in the Period 2011-2015 Authors:  Pham, Thi Xuan Thoa Nguyen, Ngoc Anh Keywords:  Capital adequacy ratio (CAR), Vietnamese banks, Basel, NIM, LIQ Issue D...

Detection o f the location o f the hazard during and after the design o f combinational circuits

Nguyen, Quy Thuong Composite material with polymer matrix - titanium particle is qidely applied in Vietnam, today. In this paper, the bending of thin polymer composite plate with Titanium particles under the effect of the steady temperature field is investigated. The paper has established the boundary problem of a simply supported composite plate reinforced by particles under the influence of steady heat transfer process.
