“…Taking the above control requirements into consideration, the ARSCM should have an ability to intelligently determine whether the seeding rate needed to be adjusted or not. In other fields, the expert control algorithm was widely used in uncertain, inaccurate and nonlinear control processes [ 22 , 23 , 24 , 25 ]. According to the characteristics of the sowing, the expert control algorithm was appropriate to be applied in this research.…”

In order to obtain desirable crop yields, grain seeds need to be sown at the optimal seed amount per hectare with uniform distribution in the field. In previous grain sowing processes, the seeding rates are controlled by the rotational speed of the flute roller which significantly effects the uniform distribution of the seeds due to disturbances, such as the reduction of the seeds’ mass in the hopper and the change of working length of the flute roller. In order to overcome the above problem, we developed an adaptive roller speed control system based on the seed flow rate sensor. The developed system can monitor and feedback actual seeding rates. In addition, based on the monitoring value of the real-time seeding rates, an adaptive roller speed control method (ARSCM), which contains an algorithm for calculating the seeding rate with a compensation, was proposed. Besides, the seeding performance of the ARSCM and that of the conventional roller speed control method (CRSCM) were compared. The results of constant-velocity experiments demonstrated that the accuracy (SA) and the coefficient of variation (SCV) of the seeding rates controlled by the ARSCM were 94.12% and 6.77%, respectively. As for the CRSCM, the SA and SCV were 89.00% and 8.95%, respectively. Under variable-velocity conditions, the SA and SCV of the proposed system were 91.58% and 11.08%, respectively, while those of the CRSCM were 88.48% and 13.08%, respectively. Based on the above results, this study concluded that the ARSCM is able to replace the CRSCM in practical sowing processes for the optimal and uniform seed distribution in the field.

“…Nowadays, where the importance of sustainable development is progressively understood, the importance of energy efficiency studies is increasing. Worldwide, grid-based electrical lighting consumes 19% of total global electricity generation, with slightly more than is used by the Organization for European Economic Cooperation and Development (OECD) countries for all purposes [62]. The lighting of streets and buildings, on the other hand, accounts for 75% of the lighting demand for electricity.…”

With the developing technology and increasing urbanization, many problems have started to arise in the use of energy resources and nature. In addition to environmental effects, energy-saving considerations constitute the main purpose of any proposed smart system. In outdoor lighting, along with the use of energy-efficient bulbs, the lighting should be done with the right method and the right way. In addition to these, an intelligent system integrated with an automatic control mechanism is needed. Incorrect outdoor lighting causes unnecessary energy consumption as well as light pollution and CO2 emission. These situations have negative consequences on both mental and physical health of the human, as well as on other living creatures and nature. Therefore, smart outdoor lighting systems offer an essential solution in preventing negative consequences that may occur with incorrect outdoor lighting. In this study, outdoor lighting requirements, light pollution and smart cities are examined in detail and the smart outdoor lighting systems within the scope of the smart cities are emphasized. As a result, the importance and necessity of the smart outdoor lighting system which provides energy-efficient and environmentally friendly structures by enabling street lamps to work smartly and efficiently are outlined.

“…Expert systems have been used in many disciplines, including the medical field and the automotive industry (Gusikhin et al, 2007; Shortliffe and Gero, 1986). Expert systems have also been used in the building industry for applications such as daylighting design (Gagne et al, 2011), building design aids (Lutton, 1995; Mazouz and Zerouala, 2001; Rosenman, 1990), outdoor lighting control (Atis and Ekren, 2016), humidity and temperature control of heating, ventilation, and air conditioning (HVAC) (Soyguder and Alli, 2009), and more (Maor and Reddy, 2003).…”

The moisture durability of an envelope component such as a wall or roof is difficult to predict. Moisture durability depends on all the construction materials used, as well as the climate, orientation, air tightness, and indoor conditions. Modern building codes require more insulation and tighter construction but provide little guidance about how to ensure these energy-efficient assemblies remain moisture durable. Furthermore, as new products and materials are introduced, builders are increasingly uncertain about the long-term durability of their building envelope designs. Oak Ridge National Laboratory and the US Department of Energy's Building America Program are applying a rule-based expert system methodology in a web tool to help designers determine whether a given wall design is likely to be moisture durable and provide expert guidance on moisture risk management specific to a wall design and climate. The expert system is populated with knowledge from both expert judgment and probabilistic hygrothermal simulation results.
