This paper assesses the feasibility of forest cover mapping and the delineation of deforestation using Japanese Earth Resource Satellite (JERS-1) Synthetic Aperture Radar (SAR) data. The assessment is carried out at five test sites in Germany (Thuringia), the UK (Kielder), Sweden (Remningstorp and Brattåker) and Russia (Chunsky). These temperate and boreal sites all have high forest cover, but ...

In social network analysis, a k-clique is a relaxed clique, i.e., a kclique is a quasi-complete sub-graph. A k-clique in a graph is a sub-graph where the distance between any two vertices is no greater than k. The visualization of a small number of vertices can be easily performed in a graph. However, when the number of vertices and edges increases the visualization becomes incomprehensible. In...

Let X = {x1, ..., xn} be a set, and let P = {P1, ..., Pm} be a set of subsets of X. The goal is to find the smallest sub-collection of sets R ⊆ P whose union covers all of X. More concretely, we can say that each xi, 1 ≤ i ≤ n represents a “skill”, and each Pj, 1 ≤ j ≤ m represents a “person”. In this case, xi ∈ Pj if person Pj has the skill xi. Then, as an employer, the goal is to find the min...

The front cover shows ABB serving the cement manufacturing industry, which it has done since 1961 with turnkey installations, electrical equipment and automation systems. In 1990, ABB recognised the MES (Manufacturing Execution Systems) business area as a natural extension to its technology portfolio. Since then, ABB has provided added value solutions that are independent from the installed pro...

Based on Landsat–7ETM + images of 2007 and 2012 Landsat–8 2018, this study took Fuyang City, Anhui Province (Yingzhou District, Yingdong Yingquan District) as the research object, made a quantitative analysis land use/cover change in City from to 2018 with Environment for Visualizing Images (ENVI) software. According data use types three phases, article analyzes development trend various main r...
