Abstract:
... The purpose of investigation is to develop an algorithm for determining the a priori accuracy assessment of the external orientation angle elements of digital images obtained from UAVs. Formulas for estimating the accuracy of external orientation elements are determined by the derivatives of many variables functions, which are the solutions of linear equations systems. These systems are obtained b ...

Abstract:
... Background: Elements of forest landscape spaces are important media through which landscape information is conveyed. Therefore, it is very important for designers and managers of forests to explore the relationship among visual behaviour, landscape preferences, and element characteristics. Purpose: This study took forest landscape spaces as the subject, discussed the characteristics of visual beha ...

Abstract:
... Considering the current trend of finding sustainable alternatives to the existing fossil-based plastics, in this review we describe what makes a bioelastomer “bio” and what this implies in terms of materials design. We analyze the current state of development of bioelastomers, including the most important types, their current and upcoming use, and their synthetic pathways. Moreover, we provide a g ...

Abstract:
... Energy transition plays a central role in efforts to reduce anthropogenic global warming. However, energy transition involves physical manifestations, for example in the form of wind turbines, photovoltaic plants, and power lines, which trigger resistance, especially among those who live in the vicinity of the (planned) plants. The reasons for this resistance are complex, as they relate to residen ...

Abstract:
... The geosystems concept is being used by academic researches and water resources management in Brazilian’s watersheds. There is a strong influence on Bertrand’s approach, which indicates that the natural and anthropic systems have the same strength to organize geographical landscape. The objective of this paper was to show a current application of the geosystems concept in planning water resources ...

Abstract:
... Digital elevation models (DEMs) contain some of the most important data for providing terrain information and supporting environmental analyses. However, the applications of DEMs are significantly limited by data voids, which are commonly found in regions with rugged terrain. We propose a novel deep learning-based strategy called a topographic knowledge-constrained conditional generative adversari ...

Abstract:
... Education is foundational to the way we see, feel, read, interpret and ‘write’ the landscapes; nevertheless, the learning processes behind these actions are not always explicit and subject to scrutiny. This short editorial, while presenting the six papers that compose this special issue on Landscape and Education, underlines the need of combining interdisciplinary viewpoints towards a greater unde ...

Abstract:
... Scattered urban development leads to non-compact urban form. In this paper, I demonstrate that Index of Moment of Inertia is a useful metric to measure compactness. However, elongated political boundaries and natural restrictions severely distort the metric, rendering it less useful for monitoring urban development. I propose a landscape shape adjustment of this metric that retains some of the use ...

However, most of the current studies have conducted resilience assessment studies on abstract complex ENs composed of points and lines, ignoring the fact that ENs are landscape entities with considerable spatial range and landscape characteristics in ecosystems. In this study, taking the Shandong Peni ...

Abstract:
... This study addresses the use of conditioners as a driver of arthropod loss in agricultural landscapes. Conditioners compress the freshly cut mowing material mechanically to destroy the evaporation-inhibiting wax layer of the grass material. This compression potentially increases the physical damage to several arthropod groups during the mowing process. We have combined an ecological field study on ...

Abstract:
... Space–time waveform-encoding (STWE) SAR can receive echoes from multiple sub-swaths simultaneously with a single receive window. The echoes overlap each other in the time domain. To separate the echoes from different directions, traditional schemes adapt single-null steering techniques for digital receive beam patterns. However, the problems of spaceborne DBF-SAR, in practice, such as null extensi ...

Optimization solutions have different selectivity but it remains unexplored. Indeterminate solutions happen without warning and may be spatially biased. Errors are hidden. These issues may undermine connectivity ...

Abstract:
... The coevolution of predators and prey has been the subject of much empirical and theoretical research that produced intriguing insights into the interplay of ecology and evolution. To allow for mathematical analysis, models of predator–prey coevolution are often coarse-grained, focussing on population-level processes and largely neglecting individual-level behaviour. As selection is acting on indi ...
