The Effect of Chelate Compounds on the Hydration Process of MgO–Al2O3 Phase System under Hydrothermal Conditions
Applied Sciences - Tập 11 Số 6 - Trang 2834
Ryszard Prorok, Jakub Ramult, Wiesława Nocuń-Wczelik, Dominika Madej
In refractory castables during heat treatment, there is a dynamic change from a hydraulic bond to a ceramic bond. During heating, the emission of water takes place; this changes the conditions inside the material to something similar to the hydrothermal ones. This influences the processes that occur during the heating of the castables, and in consequence, the properties of the final materi...... hiện toàn bộ
Performance Analysis of NoSQL and Relational Databases with CouchDB and MySQL for Application’s Data Storage
Applied Sciences - Tập 10 Số 23 - Trang 8524
Cornelia Győrödi, Diana V. Dumşe-Burescu, Doina Zmaranda, Robert Győrödi, Gianina Gabor, George Pecherle
In the current context of emerging several types of database systems (relational and non-relational), choosing the type and database system for storing large amounts of data in today’s big data applications has become an important challenge. In this paper, we aimed to provide a comparative evaluation of two popular open-source database management systems (DBMSs): MySQL as a relational DBMS...... hiện toàn bộ
Real-Time Recognition of Calling Pattern and Behaviour of Mobile Phone Users through Anomaly Detection and Dynamically-Evolving Clustering
Applied Sciences - Tập 7 Số 8 - Trang 798
José Antonio Iglesias, Agapito Ledezma, Araceli Sanchis, Plamen Angelov
In the competitive telecommunications market, the information that the mobile telecom operators can obtain by regularly analysing their massive stored call logs, is of great interest. Although the data that can be extracted nowadays from mobile phones have been enriched with much information, the data solely from the call logs can give us vital information about the customers. This informa...... hiện toàn bộ
Composition and Morphology Characteristics of Magnetic Fractions of Coal Fly Ash Wastes Processed in High-Temperature Exposure in Thermal Power Plants
Applied Sciences - Tập 9 Số 9 - Trang 1964 - 2019
Vu, Dinh-Hieu, Bui, Hoang-Bac, Kalantar, Bahareh, Bui, Xuan-Nam, Nguyen, Dinh-An, Le, Qui-Thao, Do, Ngoc-Hoan, Nguyen, Hoang
Coal-fired power stations are one of the primary sources of power generation in the world. This will produce considerable amounts of fly ash from these power stations each year. To highlight the potential environmental hazards of these materials, this study is carried out to evaluate the characterization of fly ashes produced in thermal power plants in northern Vietnam. Fly ash was firstly fractio...... hiện toàn bộ
The Perspective of Large-Scale Production of Algae Biodiesel
Applied Sciences - Tập 10 Số 22 - Trang 8181
Mladen Bošnjaković, Nazaruddin Sinaga
We have had high expectations for using algae biodiesel for many years, but the quantities of biodiesel currently produced from algae are tiny compared to the quantities of conventional diesel oil. Furthermore, no comprehensive analysis of the impact of all factors on the market production of algal biodiesel has been made so far. This paper aims to analyze the strengths, weaknesses, opport...... hiện toàn bộ
Thai Rice Vinegars: Production and Biological Properties
Applied Sciences - Tập 11 Số 13 - Trang 5929
Samuch Taweekasemsombut, Jidapha Tinoi, Pitchaya Mungkornasawakul, Nopakarn Chandet
Four types of traditional Thai rice—polished, black fragrant, glutinous and black glutinous rice—were separately used as raw material for vinegar production. During alcohol fermentation, using enriched baker’s dried yeast (S. cerevisiae) as a starter culture gave the highest ethanol content over 7 days of fermentation. The conversion of ethanol to acetic acid for vinegar production by Acet...... hiện toàn bộ
Artificial Intelligence Enabled Routing in Software Defined Networking
Applied Sciences - Tập 10 Số 18 - Trang 6564 - 2020
Wu, Yan-Jing, Hwang, Po-Chun, Hwang, Wen-Shyang, Cheng, Ming-Hua
Software defined networking (SDN) is an emerging networking architecture that separates the control plane from the data plane and moves network management to a central point, called the controller. The controller is responsible for preparing the flow tables of each switch in the data plane. Although dynamic routing can perform rerouting in case of congestion by periodically monitoring the status o...... hiện toàn bộ
An ANN Model for Predicting the Compressive Strength of Concrete
Applied Sciences - Tập 11 Số 9 - Trang 3798
Chia‐Ju Lin, Nan‐Jing Wu
An artificial neural network (ANN) model for predicting the compressive strength of concrete is established in this study. The Back Propagation (BP) network with one hidden layer is chosen as the structure of the ANN. The database of real concrete mix proportioning listed in earlier research by another author is used for training and testing the ANN. The proper number of neurons in the hid...... hiện toàn bộ
The Optimization of the Location and Capacity of Reactive Power Generation Units, Using a Hybrid Genetic Algorithm Incorporated by the Bus Impedance Power-Flow Calculation Method
Applied Sciences - Tập 10 Số 3 - Trang 1034
Insu Kim
Dynamic and static reactive power resources have become an important means of maintaining the stability and reliability of power system networks. For example, if reactive power is not appropriately compensated for in transmission and distribution systems, the receiving end voltage may fall dramatically, or the load voltage may increase to a level that trips protection devices. However, non...... hiện toàn bộ
Application of Geoinformation Systems for Assessment of Effective Integration of Renewable Energy Technologies in the Energy Sector of Ukraine
Applied Sciences - Tập 12 Số 2 - Trang 592
Olga Ostapenko, Piotr Olczak, Viktor Koval, Larysa Hren, Dominika Matuszewska, Оlenа Postupna
The scientific novelty of the results presented in this article is to substantiate and expand the possibilities of using global and local geographic information systems (GIS) to assess the potential of renewable energy sources in Ukraine. GIS analysis focused on key resource parameters can help identify territories for development of renewable energy sources and assess of their possible te...... hiện toàn bộ
