by Haiqing Han, Siru Zhu, Yanqing Dai, Qili Mao, Qin Li, Kang Shi
Abstract: In this scientific research paper, the authors have generalized the concept with regard to orthomorphic permutations(called orthomorphisms) over the Galois field. Meanwhile we have gain the enumeration formula of the total generalised linear orthomorphic permutations over the Galois field, which possesses an arbitrary prime number as the characteristic of the prime subfield. So, the local creating algorithm with regard to partial generalised linear orthomorphic permutations over the Galois general fieldis realized. Comparatively speaking, the innovativeness and originality enumeration formula with regard to linear orthomorphisms over a Galois field with characteristic 2 is a special case to contain in our novel fruits over the general field. What is more, the generalised linear orthomorphic permutations have been thoroughly discussed and generated far

by Mei Sun, Rongpu Chen, Yulian Wen, Peiyao Nie
Abstract: In view of the problem of excessive exposure in the field of quantitative investment in commodity futures and policy failure in the low volatility market environment, a new quantitative investment strategy using SVM-KNN combined classifier to hedge multi-factor futures is proposed and applied to the management of quantitative fund. The quantitative investment strategy can not only reduce the overall systemic risk of the investment portfolio, but also adapt to the long-term environment of the commodity futures market. The retest data and the results of real trading show that the SVM-KNN based hedging strategy of commodity futures is significantly higher than the traditional CTA trend tracking strategy in the annual rate of return and the SHARP ratio, and the retracting of the cross period is greatly reduced.

Enhanced Interconnected Microgrids for Water-Pumps Networks towards Zero Net Energy (ZNE) Farms
by Ahmed Abdelmaksoud, Hossam A. Gabbar
Abstract: This paper presents design of resilient interconnected microgrids to provide clean and cheap energy to water pumps infrastructure at farms during normal and emergency situations in terms of different renewable resources. Water networks are relied on every day millions of customers utilization and bring billions worth of economic goods to market. However, water network infrastructures are dependent on the electric grid, which is vulnerable to extreme weather, changing supply and demand patterns, and cyber-terrorism. The proposed microgrid includes hybrid energy storage including battery systems, which provides flexible and adaptive energy supply in view of water pumps loads. Proposed microgrid will allow sustainable operation capability with resilient performance on both of economical and technical levels. In addition, the proposed solution, based on Artificial Bee Colony Algorithm (ABC) optimization for Zero Net Energy (ZNE), ensures sustained and high performance energy supply in different operational scenarios. Integrated architecture is proposed to ensure local and supervisory operation and management of the interconnected microgrids, with best use of energy storage systems and energy distributed systems. The proposed designs are modelled and simulated in Simulink, for a proposed system of interconnected microgrids for water-pumps infrastructures, which demonstrates a reduced dependence on the electric grid. The results are both extremely impressive and promising towards a more resilient and stable energy future both for water network and its critical infrastructures.

Frost forecast - a practice of machine learning from data
by Liya Ding, Yosuke Tamura, Kosuke Noborio, Kazuki Shibuya
Abstract: 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 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 previous 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.

by Mare Srbinovska, Aleksandra Krkoleva Mateska, Vesna Andova, Maja Celeska Krsteska, Tomislav Kartalov
Abstract: The air pollution has a significant impact on humans health and global environment. In urban areas the air quality significantly decreases over the past few years. One of the methods for air pollution reduction is by installing a green walls, green roofs or by implementing green buildings in urban areas as plants have capabilities to absorb the particulate matter through their leaves. Urban green spaces especially from trees to green roofs and large natural spaces generally provide significant health benefits for residents and the community. rnThe main goals of this paper is 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 concentrations in the air in an urban area in Skopje. 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. The air quality monitoring system can be easily replicated on other locations in the urban areas of Skopje.rn

A comparative performance analysis of different machine learning techniques for SNR prediction in microcell and picocell wireless environment
by Nikola Sekulovic, Milos Stojanovic, Aleksandra Panajotovic, Milos Bandjur
Abstract: Knowledge of propagation channel conditions enables adaptive data transmission which improves the quality and efficiency of communication system. Wireless channels are characterized 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. Normalized 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.

Use of infrared radiometry in temperature measurement of plant leaf
by Hristo Hristov, Kalin Dimitrov, Stanyo Kolev
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 monitor how changing the distance between radiometer and object of study affects the heat flow 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 monitor these processes in different temperatures and with different surface areas of the object of study. We will monitor 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.

Many-Valued Tableau Calculi for Decision Logic based on Approximation Regions in VPRS
by Yotaro Nakayama, Seiki Akama, Tetsuya Murai
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 withrnthe 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.
Keywords: many-valued logic; tableau calculi; decision logic; variable precision rough set; knowledge representation.
A Bayesian Network Approach to Handle Uncertainty in Web Ontology Language (OWL)
by Sonika Malik, Sarika Jain
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, 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 the 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 Prot
