- Tác giả: Lê Tiến Lộc và Cộng sự.

- Tên tạp chí: Neuralcomputing; ISSN: 0925-2312; Volume 275, pp. 2239-2250

- ABSTRACT: Determining a network size for a fuzzy neural network structure is very important, and it is often difficult to obtain the most suitable value. This study develops a self-evolving function-link interval type-2 fuzzy neural network (SEFT2FNN) that autonomously constructs the rule base with the initial empty and the membership functions. The function-link is applied to an interval type-2 fuzzy neural network to give a more accurate approximation of the function. The adaptive laws for the proposed system are derived using the steepest descent gradient approach. The stability of system was guaranteed using Lyapunov function approach. Finally, the performance of the proposed system is verified using the numerical simulations of the nonlinear system identification and the control of time-varying plants.

05. Tên bài báo: Coverage optimization of LTE networks based on antenna tilt adjusting considering network load

- Tác giả: Phan Như Quân và Cộng sự.

- Tên tạp chí: China Communications Volume: 14, Issue: 5, May 2017 ); ISSN 1673-5447; pp. 48-58 (Communication theories and systems)

- ABSTRACT: In this paper, we investigate the coverage optimization for LTE networks considering the network load. The network coverage is defined as the number of served users of evolved Node B (eNB) which is de-termined by eNBs’ antenna tilt angles (ATA). The coverage is optimized by optimizing the number of served users based on the Modifed Particle Swarm Optimization (MPSO) algo-rithm. Simulation results show that both the number of served users by each eNB and the system throughput are signifcantly increased. As well, the average load and the bandwidth effciency of the network are improved.

08. Tên bài báo: A relationship in adrenal androgen levels between mothers and their children from a dioxin-exposed region in Vietnam

- Tác giả: Hồ Dũng Mạnh và Cộng sự.

- Tên tạp chí: Sci Total Environ. 2017 Dec 31;607-608:32-41; ISSN: 0048-9697. Doi: 10.1016/j.scitotenv.2017.06.264. Epub 2017 Jul 4

- ABSTRACT: Over the past decades, southern Vietnam has been burdened by dioxins from contaminated herbicides sprayed during the VietnamWar. In a previous study,we found that dioxin exposure decreased levels of salivary dehydro- epiandrosterone (DHEA), an adrenal androgen, in 3-year-old children. In present study, to assess the relationship between adrenal hormones disruption in lactating mothers and in children, we compared mother-child pairs from dioxin- and nondioxin-contaminated regions. In 2010 and 2011, mother-child pairs from a dioxin hotspot region (n = 37) and a non-contaminated region (n = 47) were recruited and donated breast milk and serum samples for dioxin and steroid hormones determination. Mothers were 20–30 years old and had given birth to their first child between 4 and 16 weeks previously. One year later, saliva samples were collected from the children. Dioxin levels in breast milk were determined by gas chromatography/high-resolution mass spectrometry. Salivary DHEA, cortisol in children and androstenedione (A-dione), estradiol, cortisol, and DHEA in maternal serumwere analyzed by liquid chromatography/tandemmass spectrometry. Concentrations of dioxin congeners in the hotspot regionwere 2- to 5-fold higher than in samples fromthe non-contaminated region. Salivary DHEA levels in children and serumA-dione levels inmothers were significantly higher in the hotspot region; no difference was found in the levels of other hormones. Moreover, there was a significant positive correlation between the elevated hormone levels in mothers and children (r= 0.62, p b 0.001). Several dioxin congeners exhibited strong significant dose-response relationships with salivary DHEA and serum A-dione levels. Our findings suggest that dioxin disrupts adrenal androgens inmothers and breastfeeding children through the samemechanism.

- ABSTRACT: There has been an impressive growth of open online course in recent years. However, the number of free organic chemistry courses  is limited. To create an organic chemistry course online, we need a tool that can draw chemical structure and can be embedded into the web. We found that JSME Molecular Editor was a free and  easy-to-use computer program for creating chemistry online course. We have developed interactive web-based organic nomenclature exercises by integrating JSME Molecular Editor into the website http://www.ihoahoc.com/nomenclature/Enomenclature.html. The three types of exercise were created: (i)  students are  given  structure of an organic compound, then they  have to identify a specific functional group inside this structure (ii) students are given the IUPAC name of an organic compound, then they have to draw structure of this compound (iii) students are given structures of an organic compound, then they have to write the IUPAC name of this compound. These exercises have been used for first year students at Faculty of Pharmacy, Lac Hong university, Vietnam.

- Tác giả: Trần Thanh Tuyền và Cộng sự.

- Tên tạp chí: International journal of advanced and applied sciences, 5(2)2018, pages: 44-55; ISSN: 2313-626X

- ABSTRACT: An  effective  material  handling  system  can  help  factories  meet the transportation demands for new wafer size since the size increases from 300 mm  to  450  mm.  With  advantages proved,  conveyor-based  automated materials handling system (AMHS) is chosen as the next generation transport system. However,  this  transport  system also  faces with the problems about traffic  jams  when  having  so  much  lot  in  loop  and  loading  or unloading procedures. Besides,  a  higher  priority  lots  should  enjoy  greater transportation privileges  than  those with a lower  priority.  Thus,  one  good dispatching  rule  is  very  helpful for  an  AMHS.  This  research proposes restructuring loop configurations for conveyor-based AMHS and develops an effective dispatching  rule,  named  rota-caster  in  heuristic preemptive dispatching method (R-HPD). Simulation results demonstrate that the R-HDP can provide better performances than the best existed method (DPD). The R-HPD rule reduces the average delivery time by 49.4% for hot lots and 50.5% for  normal  lots.  Moreover,  the  average delivery  time  of  normal  lot  is not affected so much when bay loading and hot lot ratio increase.

- ABSTRACT: Vietnam's economy is increasingly integrated into the international economy. The key economic sectors in which agriculture is assessed will have many favorable opportunities for development. However, in order not to fall behind, the agricultural sector must rapidly develop the value chain. Moreover, the "4 houses" link in modern agricultural production is claimed to be the best one at present. The most important issue: what farmers produce, where to sell, how the price is the only satisfactory answer when there is clarification of roles and responsibilities of each house in the linkage. The role of "role play" is also intended to promote the overall strength of the link. There are 4 main factors: Government (State), Scientist, Enterprises and Farmer are the four main factors of linkages in agricultural production. In particular, the State is "the leader", the engine of the link. Enterprises play the important role to link the remaining "4 houses" to form the raw material production area; Input support and product procurement for farmers; step by step to build brand name of agricultural products. The study results showed that there were 400 persons who include: 200 managers of enterprises, 170 farmers, 30 experts related to agricultural sector in Dong Nai province who interviewed and answered about 17 questions. The Data collected from June 2016 to April 2017. This study had been analyzed Cronbach's Alpha testing, KMO testing and the result of KMO testing used for the multiple regression. Persons’ responses measured through an adapted questionnaire on a 5-point Likert scale. The Data processed by SPSS 20.0.

- ABSTRACT: Over the past three decades of renovation, Vietnam has become self-sufficient in food with an annual export of 30 billion USD, providing livelihoods for 10 million rural households and contributing nearly 22 percent of the gross domestic product and 23-35 percent of exports. However, the growth model was mainly extensive manner, natural resources infensive-driven. Growth of this sector tends to grow slowly due to sponfaneous and small-scale production, limited technological application in agro-forestry-fisheries, the stagnation of expansion of arable lands, scarcity of water resources, advancing environmental deeradation, negative impacts 0f climate change, competition between food crops and bio-energy crops in the use of limited natural resources, rapid urbanization and a dechning agricultural labor force. In order to achieve improved and sustainable agricultural production and productivity growth largely depends on the aqdvancement of agricultural research and is effective applications at farmer's fields through the transffer of technology and innovation. In this context, agriculture 4.0 and hi-tech agriculture will play the new strategic role for agriculture growth; maintain the quality of the environmenf and other sustainable aspects. This study analyzes the current applications of agriculture 40 and hi-tech for sustainable agriculture development in Vietnam, review of factor influencing the adoption of agriculture innovations of the farm operation in Vietnam and set ofpolicy mplicalions.

- ABSTRACT: In this paper, the authors present a novel personal verification system based on the likelihood ratio test for fusion of match scores from multiple biometric matchers (face, fingerprint, hand shape, and palm print). In the proposed system, multimodal features are extracted by Zernike Moment (ZM). After matching, the match scores from multiple biometric matchers are fused based on the likelihood ratio test. A finite Gaussian mixture model (GMM) is used for estimating the genuine and impostor densities of match scores for personal verification. Our approach is also compared to some different famous approaches such as the support vector machine and the sum rule with min-max. The experimental results have confirmed that the proposed system can achieve
excellent identification performance for its higher level in accuracy than different famous approaches and thus can be utilized for more application related to person verification.

- ABSTRACT: This paper proposes an effective novel cuckoo search algorithm (ENCSA) in order to enhance the operation capacity of hydrothermal power systems, considering the constraints in the transmission network, and especially to overcome optimal power flow (OPF) problems. This proposed algorithm is developed on the basis of the conventional cuckoo search algorithm (CSA) by two modified techniques: the first is the self-adaptive technique for generating the second new solutions via discovery of alien eggs, and the second is the high-quality solutions based on a selection technique to keep the best solutions among all new and old solutions. These techniques are able to expand the search zone to overcome the local optimum trap and are able to improve the optimal solution quality and convergence speed as well. Therefore, the proposed method has significant impacts on the searching performances. The efficacy of the proposed method is investigated and verified using IEEE 30 and 118 buses systems via numerical simulation. The obtained results are compared with the conventional cuckoo search algorithm (CCSA) and the modified cuckoo search algorithm (MCSA). As a result, the proposed method can overcome the OPF of hydrothermal power systems better than the conventional ones in terms of the optimal solution quality, convergence speed, and high success rate.

- ABSTRACT: Constructing heterostructure can endow composites with many novel physical and electrochemical properties due to the built-in specific charge transfer dynamics. However, controllable fabrication route to heterostructures is still a great challenge up to now. In this work, a SiO2-assisted hydrothermal method is developed to fabricate heterostructured nickel sulfides/reduced graphene oxide (NiSx/rGO) composite. The SiO; particles hydrolyzed from tetraethyl orthosilicate could assist the surface controllable co- growth of 3D nanoflowers and 0D nanoparticles of Ni3S2/NiS decorated on reduced graphene oxide, and the possible co-growth mechanism ¡is điscussed in detail. In this composite, the heterostructured nanocomposite with different morphologies, chemical compositions and crystal structures, along with varied electronic states and band structure, can promote the interface charge transfer kinetics and lead to excellent lithium storage performances. Electrochemical measurements reveal that the NiSx/rGO com- posite presents 1187.0 mA h g1 at 100 mA g-1 and achieves a highly stable capacity of 561.2 mA h g-1 even when the current density is up to 5 Ag-1,
