Quek Hyundong Shin Singapore University of Technology and Design (SUTD) Singapore Institute for Infocomm Research (I^2R) Singapore Kyung Hee University South Korea Institute for Infocomm Research (I^2R) A^*STAR Singapore Singapore University of Technology and Design Singapore 487372 Department of Electronics Engineering Kyung Hee University Yongin-si Gyeonggi-do 17104 Korea

Fog computing is an emerging architecture intended for alleviating the network burdens at the cloud and the core network by moving resource-intensive functionalities such as computation, communication, storage, and analytics closer to the End Users (EUs). In order to address the issues of energy efficiency and latency requirements for the time-critical Internet-of-Things (IoT) applications, fog computing systems could apply intelligence features in their operations to take advantage of the readily available data and computing resources. In this paper, we propose an approach that involves device-driven and human-driven intelligence as key enablers to reduce energy consumption and latency in fog computing via two case studies. The first one makes use of the machine learning to detect user behaviors and perform adaptive low-latency Medium Access Control (MAC)-layer scheduling among sensor devices. In the second case study on task offloading, we design an algorithm for an intelligent EU device to select its offloading decision in the presence of multiple fog nodes nearby, at the same time, minimize its own energy and latency objectives. Our results show a huge but untapped potential of intelligence in tackling the challenges of fog computing。

Oligochitosan (OC) with molecular weight Mw of 5000 g/mol was prepared by gamma Co-60 ray irradiation of chitosan solution. Nanosilica (nSiO2) with the size of 10 - 30 nm was synthesized by calcination of acid treated rice husk. The mixture of 1% OC - 1% nSiO2 was prepared by dispersion of nSiO2 in OC solution. The morphology of nSiO2 in the mixture of OC-nSiO2 was measured from images of transmission electron microscopy (TEM). The effect of foliar application of the mixture of OC-nSiO2 on the induction of resistance against anthracnose disease caused by Colletotrichum gloeosporioides fungus on chili fruits was investigated. Results indicated that foliar application of OC-nSiO2 with the concentration of 60 mg/l - 60 mg/l was found to be as the optimal treatment that reduced the disease severity on chili fruits to 22.2% compared with 90.0% of the control. Thus, OC-nSiO2 hybrid material could be considered as an effective biotic elicitor to prevent anthracnose disease infection for chili fruits. Furthermore, the prepared OC-nSiO2 hybrid material can also be used as an environmentally friendly agrochemical product for sustainable development of agriculture.

Streaming Potential and Zeta Potential Measurements in Porous Rocks

引用

Journal of Geoscience and Environment Protection 2018年第11期6卷 89-100页

作者： Luong duy Thanh Thuyloi University Hanoi Vietnam

The measurements of the streaming potential coefficient and the zeta potential of two consolidated samples saturated with four monovalent electrolytes at different electrolyte concentrations have been performed. The experimental results show that the streaming potential coefficient and the zeta potential in magnitude both decrease with increasing electrolyte concentration for all electrolytes. It is also shown that there is a dependence of the streaming potential coefficient on types of electrolyte for a given sample. This is explained by the dependence of the zeta potential and the electrical conductivity on types of electrolyte. Additionally, the variation of the zeta potential with types of electrolyte is also reported and qualitatively explained. From experimental data on the streaming potential coefficient and the zeta potential, the empirical expressions between the streaming potential coefficients, the zeta potential and electrolyte concentration are also obtained. The obtained expressions have the similar forms to those available in literature. However, there is a deviation between them due to dissimilarities of fluid conductivity, fluid pH, mineral composition of porous materials and temperature.

汉语当前是世界上使用人数最多的语言之一。现在有很多国家推广学习汉语,比如美国、日本、韩国、东南亚国家、非洲国家等。许多学习者将汉语作为第二语言进行学习,这是汉语自身国际地位提高的一个重要标志。越南是一个发展中国家,随着经济的发展,越来越多越南人为了不同目的而学习汉语。在越南,学习汉语的人数日益增加。汉语普通话的三个要素包括语音要素、词汇要素和语法要素。其中,语音是汉语的基本的表现形式,语音学习是一个很重要的环节,语音障碍是学习汉语障碍的第一个关口。在地理上,越南分为北部、中部和南部三部分,每个地方的语音特点都不一样。本人作为一名越南南方学习汉语的学生,在学习汉语的过程中发现自己和朋友们遇到一些相同的语音问题。本人很想解决这些语音偏误,所以查阅了很多文献,发现针对越南南方学生的研究很少。所以,本人决定研究越南南方学生学习汉语语音常见的偏误以及纠正方法,希望能弥补目前针对越南南方学生学习汉语语音偏误研究的欠缺。本研究分成六章:第一章是引论,简单介绍选题缘由、文献综述、研究意义与方法、核心概念界定及理论基础。第二章是越南语南方方言和汉语普通话的语音对比,进行越语-汉语声母、韵母、声调三个方面的对比,并找出汉语普通话和越南南方方言语音的共同之处与不同之处。第三章是本文的核心内容,讨论越南南方学生学习汉语声母、韵母、声调常见的偏误。第四章分析越南南方学生汉语语音偏误的原因,这章也按照语音的三个方面来进行分析。第五章是语音偏误的纠正方法与教学对策,是论文里很重要的部分。第六章是总结。

Phylogenetic Analysis of Baculovirus Isolates from Diseased Insects in Southern Vietnam

Open Journal of Genetics 2014年第5期4卷 378-384页

作者： Nguyen Thi Phuong Thao Nguyen Thi Thuy Nguyen Khac duy Doan Chinh Chung Do Minh Si le Thanh Long Institute of Tropical Biology Vietnam Academy of Science and Technology Ho Chi Minh City Vietnam University of Science Ho Chi Minh City Vietnam

The aim of this study was to investigate the molecular identification and assess the genetic relationship of baculovirus isolated from Southern Vietnam. The diseased insect samples were collected from the different fields. The partial sequence of 450 base pairs of lef-8 gene was amplified and sequenced to assess the genetic variations of baculovirus isolates specific for Spodoptera litura, Helicoverpa zea, and Helicoverpa armigera. The sequences alignment demonstrated that Helicoverpa zea specific isolates exhibited six single nucleotide polymorphic sites. Whereas, twenty five single polymorphic sites were found in Spodoptera litura specific isolates. Thus, Spodoptera litura specific isolates were higher polymorphic than Helicoverpa zea specific isolates. The genetic distance analyses showed that the distance between Vietnamese baculovirus isolates and Group II Alphabaculovirus isolates was lower than other Baculovirus groups. The phylogeny of Vietnamese isolates in relation to other baculovirus isolates was also determined using partial sequences of lef-8 gene. The phylogenetic tree placed all Vietnamese isolates in Group II Alphabaculovirus, where seven Vietnamese Helicoverpa zea specific isolates were most closely related to Helicoverpa zea SNPV, fourteen Vietnamese Spodoptera litura specific isolates were located with Spodoptera litura NPV-G2 in one clade and a Vietnamese Helicoverpa armigera isolate was appeared to be closely related to Helicoverpa armigera SNPV-NNg1, Helicoverpa armigera NPV-C1, Helicoverpa armigera NPV-G4.
