Authors:Liya Ding, Yosuke Tamura, Kosuke Noborio, Kazuki Shibuya Pages: 191 - 203 Abstract: Among the efforts in frost forecast using machine learning techniques, a well-adopted method is to first apply time series forecast for the lowest temperature at future time points, such as the next a few days, and then apply predictive model to predict the event of frost at these time points using corresponding temperature forecasted. According to the domain understanding, there exists some 'cause-effect' between environment factors, including temperature and others, and the occurrence of frost in a few hours' period. A new modelling concept has been proposed by Ding et al. to capture such cause-effect. Preliminary experiments showed encouraging results with a sample of minute-level sensor data collected in Ikuta campus of Meiji University. In this article, as a continuation of the work, we shall further discuss methods of modelling, including causal models and associative models, and propose a framework of hybrid system in supporting frost forecast of short-term (e.g., a few hours) as well as that of relatively longer periods (e.g., a few days). More experiments are provided, and the issues of performance evaluation are discussed.

Authors:Mare Srbinovska, Aleksandra Krkoleva Mateska, Vesna Andova, Maja Celeska Krstevska, Tomislav Kartalov Pages: 204 - 211 Abstract: The air pollution has a significant impact on human's health and global environment. The air quality significantly decreased over the past few years. One of the methods for air pollution reduction is by installing green walls, green roofs or by implementing green buildings in urban areas as plants have capabilities to absorb the particulate matter through their leaves. The main goals of this paper are to present system for air quality monitoring using sensor network technology that can be easily deployed in polluted areas and to examine the influence of the experimental green wall setup to particulate matter more precisely PM10 and PM2.5 concentrations in Skopje, Republic of North Macedonia. Furthermore, the paper presents the preliminary results of the ongoing experiment developed to evaluate the impact of green walls in reduction of air polluting particles' concentrations. The air quality monitoring system can be easily replicated on other locations in the urban areas of Skopje.

Authors:Nikola Sekulović, Miloš Stojanović, Aleksandra Panajotović, Miloš Banđur Pages: 212 - 218 Abstract: Knowledge of propagation channel conditions enables adaptive data transmission which improves the quality and efficiency of communication system. Wireless channels are characterised by highly dynamic time-varying nature. This means that information regarding propagation channel condition obtained by channel estimation can become outdated because of delay caused by processing and feedback phases. In fast fading environments, prediction of channel based on channel states in previous moments can ensure timely information. In this paper, a comparative performance analysis of an echo state network (ESN), an extreme learning machine (ELM) and least squares support vector machines (LS-SVM) for prediction of wireless channel conditions for single-input single-output (SISO) systems in microcellular and picocellular environments is carried out. Normalised mean squared error (NMSE) and time consumption are used as performance indicators. The experimental results on measured values for signal-to-noise ratio (SNR) show that all models have better and comparable prediction accuracy in microcell environment, while prediction framework based on the ESN outperforms the others in picocell environment.

Authors:Hristo I. Hristov, Kalin L. Dimitrov, Stanyo V. Kolev Pages: 219 - 226 Abstract: Through our present work we will show the importance of infrared radiometry in conducting various plant studies. We will look at the factors that affect temperature measurements and their significance. We will analyse how changing the distance between a radiometer and an object of study affects the heat flux entering the radiometer aperture from an object, and then how changing the distance between them affects the total remaining heat flux entering the radiometer aperture. We will analyse these processes in different temperatures and with different surface areas of the object of study. We will observe the change of the flux entering from the object of study and the change in the total remaining heat flux entering the radiometer aperture, when the scene is made of insulation material. We will draw conclusions about the significance of the distance between the thermal camera and the object of study.

Authors:Ari Aharari, Chunsheng Yang Pages: 227 - 234 Abstract: The world population is increasing at a fast rate, and as results need for food is also growing briskly. The traditional method of agriculture is not sufficient enough to cover the needs of the market. On the other hand, the aging of agricultural workers has progressed rapidly, and the successor problem is becoming more serious. Under such circumstances are coming out also new farmers that will help the beginner to agriculture. However, the establishment of farming technology has become a significant management challenge for new farmers. In this paper, we focused on automation in agriculture by applying IoT technologies. The proposed system is utilising to monitor the environmental information during the experiment of producing the red radish. The sensor data is analysed to find the relation between ecological parameters and the growth results. The result of the proposed system was satisfactory as the first step in much deep measure development.

Authors:Yotaro Nakayama, Seiki Akama, Tetsuya Murai Pages: 235 - 242 Abstract: Rough sets theory is studied to manage uncertain and inconsistent information. While the Pawlak's decision logic of rough sets is based on classical two-valued logic, this causes inconvenience for the various reasoning. In this paper, we propose many-valued logics, especially a three-valued logic, as the deduction system for the decision logic of rough sets. To enhance the decision logic from classical bivalent logic to three-valued logic, we adopt variable precision rough set (VPRS). As a deductive basis for three-valued decision logic, we define a consequence relation based on three-valued semantics to constructing a deduction system with the semantic tableau. We show to deal with two types of the third value of three-valued semantics one is unknown, and the other is inconsistent using Belnap's four-valued interpretation.

Authors:Sonika Malik, Sarika Jain Pages: 243 - 250 Abstract: In information management systems ontology play a vital role. An ontological application should include a mechanism for handling uncertainty. Ontological innovations are to become the web's future in the coming period, but there are still some features such as exceptions, vulnerability and default values missing. Ontological languages such as OWL and RDF are by necessity distinct in nature, so ambiguous details cannot be treated. In this research, article uncertainty is handled in the ontology by Bayesian network. A probabilistic model of uncertainty available in the knowledge base is the Bayesian network. The Bayesian network is a conceptual model that is ideal for the representation and analysis of ambiguity and information found in data. The probability of uncertainty can be used for many real-life scenarios in the knowledge-base. We also introduced defaults and exceptions along with uncertainties to enhance performance and improve the OWL features. The source code is then translated to a jar-file with maven and it can be used in Protégé itself.
