“…As an emerging trend, RTK-based guidance systems are employed, in particular, in all phases of the agricultural operations to perform every activity on the crop, from soil preparation to harvesting, and they help farmers to choose consistent driving strategies, enabling an increase in accuracy and productivity and a decrease in time and operating costs. GNSS-based mechanic guidance systems can be used to provide real-time positioning information to support the precise maneuvering of tractors, avoiding diversions from the desired trajectory [36,37].…”

Variable Dampers to Mitigate Structural Demand to Wind Turbines: The Role of the Monitoring System Features for the Effectiveness of the Control Strategy

In the last decade, some researchers and professionals have been engaged in the study of methods and techniques that can build high wind turbines while containing construction costs within the limits of economic convenience. Among the most promising solutions is that of using innovative devices to mitigate the structural demand for the towers. The reduction in the stress demand in the foundation makes the strategy particularly interesting for the repowering of existing plants, where it is convenient not to demolish and rebuild the foundation, but rather to reuse the existing one for the new plant. A semi-active vibration control strategy, based on the adoption of controllable dissipative devices, is presented herein. The proposed technique requires the tower to be equipped with a measurement system suitable for the real time monitoring of structural response. Performing reliable high-frequency measurements of the horizontal displacement of points located at heights of tens of meters is not simple. With the purpose of assessing the efficiency and feasibility of Global Navigation Satellite System (GNSS)-based systems for the control of wind turbine structures, the proposed paper tries to investigate the characteristics and data processing techniques that are able to make the GNSS useful for such applications. Several numerical simulations were carried out with reference to a case-study wind turbine to quantitatively assess how the performance of the control system changes as the features of the monitoring system worsen, and finally to draw conclusions and suggestions for the minimum performance that monitoring devices must have for an effective reduction in structural demand.

“…For instance, the application of heavy machinery on clay soils and the use of plowing result in soil compaction. This process of soil degradation prevented water infiltration in deeper layers which leads to the stagnation of water in the surface layer [23][24][25].…”

The United Nations Convention to Combat Desertification defines 'land degradation' as a reduction or loss of the biological and economic productivity resulting from land-use mismanagement, or a combination of processes, such as soil erosion, deterioration of soil properties, and loss of natural vegetation and biodiversity. Land degradation is hence an interactive process involving multiple factors, among which climate, land-use, economic dynamics and socio-demographic forces play a key role. Especially in the Mediterranean basin, joint biophysical and socioeconomic factors shape the intrinsic level of vulnerability of both natural and agricultural land to degradation. The interplay between biophysical and socioeconomic factors may become extremely complex over time and space, resulting in specific patterns of landscape deterioration. This paper summarizes theoretical expectations and empirical knowledge in the field of soil and landscape degradation in Mediterranean Europe, evidencing the intimate relationship between agriculture and socio-demographic factors of growth (or decline) of rural areas. Understanding spatio-temporal trends of each factor underlying land degradation and the related background context is a key tool in the assessment of the spatial distribution of vulnerable and critical land to degradation. Empirical results of a permanent monitoring of land degradation contributes to delineate more effective conservation policies through identification of target areas requiring specific actions for biodiversity and landscape protection. With increasing human pressure on rural environments, a diachronic evaluation of patterns and processes of land degradation reveals particularly appropriate in a both positive and normative perspective, prefiguring new actions for soil conservation and landscape valorization under global change.

“…An inherent algorithm was planned to find the ideal route of typical mobile tourists in Jeju, verifying the effectiveness of the planned system. Furthermore, strategies of sustainable development and energy effectiveness must be followed [22,[28][29][30][31][32][33][34][35][36][37]. Inside the sector of Industry 4.0, "Smart Energy" can be defined as a level of new energy supply systems [17,[20][21][22][23][24], focused on monitoring energy consumption.…”

Industry 4.0 designates the recent digital revolution in the industrial sector, evolving from the comprehensive networking and automation of all the productive areas. Equipment, machinery, materials and products permit to (i) distinguish dealing out environmental settings and current status via sensors; (ii) join them through fixed software; and (iii) progress production procedures in an exclusive method. Additionally, Industry 4.0 exposes new trials to enterprises, especially small and medium-sized enterprises (SMEs). Firms should advance approaches to (i) achieve chances of innovation and digitalization; (ii) expand their processes; and (iii) define innovative business models. Based on these premises, a well-organized political, legal and infrastructural outline is essential to build up a business having an Industry 4.0 approach. Though bigger firms can get ahead through innovation processes and predicting the potential digitalization risks for their business models, SMEs may be in trouble. The present editorial aims to offer relevant research outcomes that has been carried out on such a current and emblematic theme, offering new perspectives and opportunities especially for SMEs.
