Applying the attributed prefix tree for mining closed sequential patterns - Pham Thi ThietThis paper proposed an algorithm for mining closed sequential patterns. This algorithm combined the parent–child relationship between nodes on prefix tree and the definition of closed sequential pattern to determine whether a sequential pattern is a closed sequential pattern by adding IsCSP field into each sequential pattern node on the prefix t...

Liver intensity determination in the 3d abdominal mr image using neural network - Le Trong NgocDeveloping a fully automated scheme for liver segmentation is a challenge and has been investigated by researchers worldwide. In the intensity based methods, identifying the intensity range of liver is an important step. In this study, we investigate in identifying the intensity range of the liver in the 3D MR abdominal images by using the histo...

Glucose correction in handheld devices by reducing the effect of hematocrit - Huynh Trung HieuThe handheld devices or POC are popular to measure glucose values. However, their accuracy is affected by some factors, in which the hematocrit is the most highly affecting one. This paper presents an approach for reducing the effects of HCT, in which HCT is estimated from the transduced current curve by employing the single hidden layer feedfor...

A novel method for designing the controller of a lcl-Filter-based grid-connected inverter with considering varying system parameters - Nguyen Trung NhanTo test the dynamic response of the proposed control system, the reference current was changed from 7 ampere to 12 ampere (peak) at t = 0.1 s when the system is operating (note that the change occurs when the a-phase current arrives at the zero value). This Figure shows that the dynamic response of the proposed controller is rapid for this case....

Determination of arsenic content in wastewaterfed fish pond in Hoang mai district, Hanoi, Vietnam - Le Thai HaThe total As concentration in the water samples ranged from 23.22 to 45.86 µg/L. The highest levels were found in the inlet water and the lowest were in the outlet water. About 14% of As entered the fish pond in the SPM form. The lower As contents in the outlet sampling point may result from some natural removal processes such as sedimentation a...

The cultivation of spirulina platensis on vertical aeroponic substrates - Nguyen Thi LienAs with all plants, micro-algae photosynthesize, they assimilate inorganic carbon for conversion into organic matter. Although light is an essential substrate for photosynthesis, high light intensity causes a decrease of photosynthetic activity. The growth rate of algae is maximal at saturation intensity and decreases with both increase or decre...
