Article
Full-text available
The objective of the article is to propose a suitable management model which could be used to exploit rich and diversified data in different formats (i.e. text and spreadsheet). Besides, we also propose specific solutions based on a common Big Data platform, including: (1) HDFS (Hadoop Distributed File System) of Hadoop, which could be used in file...

Finding an optimal design for the environmental surveillance network is a realistic need for any ecosystem manager. There are two main factors related to the optimization of a surveillance network: number of sampling points (deciding the sampling density) and locations of such sampling points. This paper aims at proposing an agent-based model to ad...
Conference Paper
Full-text available
This paper aims at introducing a novel general simulation model named Unit Disk Graph-based Surveillance Network Model (USNM) for an ecosystem. This model can be applied for multiple types of surveillance network, supported by two main techniques: (1)Unit Disk Graph and (2)clustering based on the correlation measures. USNM is a part of a bigger mul...
Conference Paper

This paper aims at modeling a brown plant hopper (BPH) surveillance network, called BPH surveillance network model (BSNM). In this model, we apply the Unit Disk Graph (UDG) technique to setup a graph with multiple surveillance nodes (light traps). An agent-based model (ABM) is built to model some necessary environmental and ecological factors, in w...

This paper is aimed at introducing a new dynamic and smart campus architecture based on spatial data infrastructure and distributed ontology. This architecture helps to integrate and connect between a spatial infrastructure and multiple available IT systems implemented and operated on one or multiple university campuses. This novel architecture of...

The article objective is proposing a new model for managing large unstructured data set existed in the text files, spreadsheets form. The proposed model is based on the open source set of Big Data with service integration and link data normalization, including: (1) HDFS (Hadoop Distributed File System) used in the file management, (2) Lucene set up...
Thesis
Full-text available
Insect invasions represent major threats for rice ecosystems. In South-East Asia, the two most critical kinds come from the white-back plant hopper (WBPH) and the brown plant hopper (BPH). In Vietnam in particular, BPHs critically damage rice yields not only through direct attacks on young rice branches but also through various indirect damages, li...

Bài viết giới thiệu mô hình mô phỏng sự phát tán của rầy nâu dưới sự tác động của côn trùng thiên địch trên đồng ruộng. Ngoài thiên địch, bài viết cũng đề cập đến sự tác động của yếu tố sinh thái và tự nhiên lên quá trình sinh trưởng, phát tán rầy. Kết quả mô phỏng của mô hình hỗ trợ tích cực việc phòng và chống rầy. Mô hình được xây dựng trên nền...
Conference Paper
Full-text available
Integrated environmental modelling approaches, especially agent-based modelling ones, are increasingly used in large-scale decision support systems. A major consequence of this trend is the manipulation and generation of a huge amount of data in simulations, which require to be efficiently managed. In this paper, we present a Combination Framework...
Technical Report
Full-text available
This research aims at introducing the general model for a surveillance network and all related data models. To do it, multiple assumptions about the environment are proposed and implemented in the general model, where the observed variables are assumed as Gaussian process. We define a Correlation-based Surveillance Network Diagram (CSND) that works...

Conference Paper

This paper is aimed at introducing a new approach to estimate the density of Brown Plant Hoppers (BPHs) at provincial scale. The model is based on the topology of a light-traps network (to gather the information about the BPHs) of a province. The BPHs density is determined based on Unit Disk Graph technique where each light-trap becomes a vertex an...

Question
I'm working on Software Requirements and I have to deeply understand on Requirements Management (REQM) and Requirements Development (RD). Shared documents are mostly written for theoretical processes and principles, so I need to understand about the practices.
Please share me several related documents!
Thank You for Supports!
Question
Pertaining to the need of data integration (or higher as data governance), a hybrid solution of data warehouse and big data is proposed in:
I think that this solution is really interesting and hope that this solution can be a big trend in the future. I hope that some of you have experencies for such solution and can share it (eg. data integration centers and implemented technologies, basic theories, required standards).
Thank you!
Question
Dear all,
I'm working on a project needing to integrate data from various sub data-centers. These sub data-centers are heterogeous in technology and function.
I know there are some popular models used for this purpose, such as data warehouse, SOA, ..., and also other modern ones based on big data. However, I don't know which is the best choice for my case.
Is there some suggestion for this solution?
Thank You and Best Regards,
Truong Xuan Viet
Question
Dear all,
We are finding a solution for data integration in a large scale territory, with multiple eco-social aspects. The final goal is building a solution for data governance with related elements such as the data steward, data lineage, data provenance, etc ...
Is there really a theory or a standard for this need (a Hadoop-based solution could be better)? Please share your experiences with us if any!
Thanks and Best Regards,
Question
Dear all,
I'm working on time series forecasting and I need to find an appropriate Java API. Are there some ones having the experience on this subject? I see that Weka can be used for this purpose, but I can not reach the correct answer for that?
Thanks for answers,
Question
Dear all,
I'm trying Cloudera Search, the Solr is alrealy integrated inside. So, the configurations of using solrconfig.xml and schema.xml are quite different with the 'pure' Solr. Are there some helps?
Thanks,
Viet
Question
Dear all,
I'm finding a solution for extracting the information (as a search engine) from the unstructured data such as the .docx, .xlsx, .pdf, ... files (internal documents).The expected tool is based on Hadoop system. If you have some experiences for this works, please share me some solutions!
Thank You So Much,
Viet
Question
I'm working with some metaheuristic algorithms in agent-based model. I have to compare the efficiency between the metaheuristic algorithm and the covariance approaches (e.g D-optimal, E-optimal). If you have some ideas, please share with me. Thanks in advances!
