Factors affecting the recovery yield and the purity of n-Acetyl glucosamine from chitin hydrolysate - Dang Thi HuongTrong nghiên cứu này ảnh hưởng của tỉ lệ cồn/dịch thủy phân cũng như mức độ cô đặc của dịch thủy phân đến hiệu suất thu hồi và độ tinh sạch của NAG đã được khảo sát. Kết quả cho thấy tỷ lệ tối ưu của cồn/dịch thủy phân là 9. Nếu tiếp tục tăng tỉ lệ này lên 11 cũng chỉ làm tăng lên không đáng kể hiệu suất thu hồi từ 74,47 % lên 75,3 9 % và độ tin...

Offloading lte data traffic with named-Data networking integration - Ong Mau DungIn this paper, we discuss a new framework that not only offloads Internet mobile traffic but also increases QoS by proposing a new type of cache decision and replacement policy FGPC. In our algorithm, it engages NDN nodes with higher hitting rate by effective caching and increases offloading server significantly. Furthermore, we carry out simula...

Model checking early requirements specifications in alloy - Ton Long PhuocIn this paper, we propose a new approach of automatically generating code and verifying from the specification language Alloy. By adopting Alloy as a domain modeling language, we can easily visualize models using Alloy Analyzer which can be understood by the domain experts. In addition, we can implement their instances and check their correctnes...

Intelligent distributed cooperative control for multiple nonholonomic mobile robots subject to unknown dynamics and external disturbances - Nguyen Tan LuyThis paper provides a new distributed optimal cooperative tracking control method with disturbance rejection for multi-mobile robots. The method removed the phenomenon of separating the main controller and transformed a structure ACD with three NNs into a structure with only one NN for which the novel NN weight-tuning laws were designed. The onl...

A statistical approach for packer identification - Nguyen Minh HaiThis paper proposes a new approach on packer identification using statistical approach. We first develop BE-PUM as a generic unpacker tool with the obfuscation technique detection. During on-the-fly disassembly, BE-PUM measures the frequency of obfuscation techniques and extracts the obfuscation technique relevance in packer based on the new wei...

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...
