A novel approach to determine the size of samples granular wastes is proposed, forwarding concept “number particles”, as previously introduced by authors. To be representative with a minimum error, it was demonstrated that at least 100 particles showing presence measurand, shall collected in sample. Waste are usually characterized size-concentration relationships. However, waste sampling standa...

Structures of tree topology are frequently encountered in nature and in a range of scientific domains. In this paper, a multi-step framework is presented to classify tree topologies introducing the idea of elastic matching of their sequence encodings. Initially, representative sequences of the branching topologies are obtained using node labeling and tree traversal schemes. The similarity betwe...

Creating sustainable bioeconomies for the 21st century relies on optimizing the use of biological resources to improve agricultural productivity and create new products. Arbuscular mycorrhizae (phylum Glomeromycota) form symbiotic relationships with over 80% of vascular plants. In return for carbon, these fungi improve plant health and tolerance to environmental stress. This symbiosis is over 4...

Soil type maps at the scale of 1..1 000 000 are used extensively to provide soil spatial distribution information for soil erosion assessment and watershed management models in China. However, the soil property maps produced through conventional direct linking method usually suffer low accuracy as well as the lack of spatial details within a soil type polygon. This paper presents an effective m...

Sampling of any geological formation needs comprehensive knowledge of the rock genesis, through the dia- and epigenetic processes (secondary alterations) up to the physical properties and the chemical and mineralogical composition of the rock. Well established theoretical knowledge should be complemented by practical experience. Besides the geological exploration of a raw material, its represen...

Obtaining samples that represent original fluid of reservoirs optimizes reservoirs management. The optimized management increases recovery. Also, selecting and performing proper Improved Oil Recovery (IOR) or Enhance Oil Recovery (EOR) programs depend on collecting representative samples. Achieving accurate compositions of original in-situ fluid prevents overdesigning surface facilities. Re...

The design of many information processing systems rely on representative samples of data. Such data may not be readily available due to the cost of acquiring the data or due to privacy concerns. This situation can be alleviated by constructing representative samples from available data sets. This can be done by applying appropriate transformations, e.g., injecting noise, that preserve semantic ...
