The subjects of the study are economic and legal opportunities risks green mining cryptocurrencies. purpose work is to analyze processes organizing in Russian Federation, formation a model its regulation with an emphasis on possibilities stimulating mining, as well use cryptocurrencies cross—border operations under sanctions pressure. conclusion made about need for cryptocurrency taking into ac...

Association of methane with coal poses a serious explosion risk in underground coal mining. Besides, it is a potent green house gases significantly contributing to global warming. Therefore, its commercial exploitation is being widely recognised as (a) a fuel resource to bridge the energy gap (b) making coal mining safer (c) providing cleaner energy and (d) checking the building of green house ...

A large number of hypotheses have been proposed to explain the adaptive significance and evolution of the endophagous-feeding mode, nutritional benefits being considered to be one of the main advantages. Leaf-mining insects should feed on most nutritional tissues and avoid tissues with high structural and/or biochemical plant defences. This selective feeding behaviour could furthermore be reinf...

This paper discusses the inherent difficulties in evaluating systems for theme detection. Such systems are based essentially on unsupervised clustering aiming to discover the underlying structure in a corpus of texts. As the structures are precisely unknown beforehand, it is difficult to devise a satisfactory evaluation protocol. Several problems are posed by cluster evaluation: determining the...

Abstract This paper reports on a design science research (DSR) study that develops principles for “green” – more environmentally sustainable data mining processes. Grounded in the Cross Industry Standard Process Data Mining (CRISP-DM) and review of relevant literature methods, Green IT, IS, identifies eight fall into three categories reuse, reduce, support. The an evaluation strategy provides e...

The life cycles of many organisms are constrained by the seasonality of resources. This is particularly true for leaf-mining herbivorous insects that use deciduous leaves to fuel growth and reproduction even beyond leaf fall. Our results suggest that an intimate association with bacterial endosymbionts might be their way of coping with nutritional constraints to ensure successful development in...

This chapter introduces a preference-based recommendation procedure in a green product information retrieval system. It constructs a green information management system based on data mining technology. Green products and relevant green regulations were collected and then integrated in a content-based and collaborative filtering method to provide a preference-based query interface for green prod...

This paper provides the first systematic analysis of the choice of green office space by commercial tenants. We analyze the decisions of more than 11,000 tenants to choose office space in green buildings or in otherwise comparable non-green buildings located nearby. We formulate six propositions to explain why specific firms and industries may be more likely to lease green space. We test these ...
