Research ArticleOpen accessIn the abstractEvaluating Plant Species Suitability for a Substrate-Free Tropical Green RoofBruno R. Silva, André Mantovani, Dulce G. Mantuano et al.Greenroofs reduce building exterior-interior thermal flux and mitigate high internal air temperatures, especially in tropical climates. Tropical greenroofs are given little attention and their use remains restricted to a very low percentage of roofs due to high costs compared to traditional roofs, weight overload (mainly due to the chosen substrate) and potential waterproofing problems. We here present an alternative greenroof … …OnLine Journal of Biological Sciences, Vol. 18, Issue 4 · 11 Oct 2018 · 7,523 accessesView PDFCite
Research ArticleOpen accessIn the abstractModel for Automated and Improved Utilization of Existing Computer Resources on an Example of Web ServersDino Alagić, Ivan MagdalenićInformation technology is under constant innovation pressure to provide the highest level of data availability – i.e., the continuous functioning of operating systems. This is the very reason for an accelerated development of complex systems encompassed by the term cloud computing. Among other things, such solutions are aimed to ensure high-level availability of complex systems and architecture. Numerous studies indicate … …Journal of Computer Science, Vol. 14, Issue 2 · 2 Mar 2018 · 8,270 accessesView PDFCite

EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethod of Efficiency Improvement in District Heating SystemsAndrey Gennadiievich Batuhtin, Maxim Stanislavovich Bass, Sergey Anatoljevich Ivanov et al.The article determines application potential of solar energy in conditions of sharply continental climate. It presents an energy-efficient solar energy recovery scheme in district heating systems, allowing to reduce capital costs and maintenance charges and to increase degree of substitution of conventional sources of heat. Versatility of systems using this method results in its multi-zone application: From a cottage-type house … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 1 Feb 2016 · 7,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractA REFINEMENT OF DIJKSTRA'S ALGORITHM FOR EXTRACTION OF SHORTEST PATHS IN GENERALIZED REAL TIME-MULTIGRAPHSSiddhartha Sankar Biswas, Bashir Alam, M. N. DojaThe networks of the present day communication systems, be it a public road transportation system or a MANET or an Adhoc Network, frequently face a lot of uncertainties in particular regarding traffic jam, flood or water logging or PWD maintenance work (in case of public road network), attack or damage from internal or external agents, sudden failure of one or … …Journal of Computer Science, Vol. 10, Issue 4 · 14 Dec 2013 · 7,260 accessesView PDFCite
Research ArticleOpen accessIn the abstractCOST-BENEFIT ANALYSIS OF A SINGLE UNIT SYSTEM WITH SCHEDULED MAINTENANCE AND VARIATION IN DEMANDGulshan Taneja, Reetu MalhotraThe present paper analyses the reliability and cost-benefit for a single unit system with scheduled maintenance and variation in demand. As Change in demand affects the production of system also, hence sometimes, the system needs to be shut down when the number of produces are in excess as compared to those demanded. Revenue in case of both types of up … …Journal of Mathematics and Statistics, Vol. 9, Issue 3 · 30 May 2013 · 7,197 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalytic and Nonlinear Prognostic for Vehicle Suspension SystemsAbdo Abou Jaoude, Khaled El-TawilPredicting Remaining Useful Lifetime (RUL) of industrial systems becomes currently an important aim for industrialists knowing that the expensive failure can occur suddenly. As the classical strategies of maintenance are not efficient and practical because they neglect the evolving product state and environment, the recent prognostic approaches try to fill this gap. This approach shows to be important in ensuring … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 23 Feb 2013 · 7,522 accessesView PDFCite
