MAR: A structure-based search engine for models [article]

José Antonio Antonio Hernández López, Jesús Sánchez Cuadrado
2020 arXiv   pre-print
However, to date, there has been little success in creating a generic and efficient search engine specially tailored to the modelling domain. In this paper we present MAR, a search engine for models.  ...  The search takes the model structure into account using the notion of bag of paths, which encodes the structure of a model using paths between model elements and is a representation amenable for indexing  ...  ACKNOWLEDGMENTS Work funded by the Spanish Ministry of Science, project TIN2015-73968-JIN AEI/FEDER/UE and a Ramón y Cajal 2017 grant.  ...

Ten Blue Links on Mars [article]

We intend for this research problem to be aspirational and inspirational - even if one is not convinced by the premise of Mars colonization, there are Earth-based scenarios such as searching from a rural  ...  In this paper, we formulate the searching from Mars problem as a tradeoff between "effort" (waiting for responses from Earth) and "data transfer" (pre-fetching or caching data on Mars).  ...  For searching on Mars, we add an appropriate delay for each interaction with the search engine.  ...

Material Choices for Mars

J.L. Marcy, A.C. Shalanski, M.A.R. Yarmuch, B.M. Patchett
2004 Journal of materials engineering and performance (Print)  
The environment on Mars presents many unique challenges when designing a space suit for use during human exploration.  ...  Previous NASA suits were analyzed prior to choosing new materials for a Mars suit, using Ashby criteria where applicable, and specific commercial information where necessary.  ...  The search limits (i.e., a maxi-mum value, minimum value, or specific range) were based upon either existing suit materials or similar engineering applications.  ...
