In this paper we criticize the existing contradictions in the context of bone marrow donor records in Spain. On the one hand there is the necessity to register as many patients as possible to maximize the opportunities to access a bone marrow transplant and on the other the always important economic issue of having to perform the relevant histocompatibility tests. In fact, these records are globally coordinated with each other to provide a wide range of potential donors and make better (...) use of existing resources. It should be noted that many patients who should have a transplant but who do not achieve a sufficient donor support must follow a medical treatment with high economic costs with tragic results for many of them. For example, those suffering from certain types of leukemia, when not finding that compatible donor, must follow chemotherapy-based treatments. There are also cord blood units banks which allow performing these transplants, also coordinated at the international level. Therefore, according to the principle of reciprocity, it is not justifiable that some countries are doing an important economic effort to have a large registration while others take advantage without making an equivalent effort according to their economic and population size.

In the present work, an artificial neural network (ANN) will be developed to estimate the relative rotation and translation of the autonomous mobile robot (AMR). The ANN will work as an iterative closed point, which is commonly used with the singular value decomposition algorithm. This development will provide better resolution for a relative positioning technique that is essential for the AMR localization. The ANN requires a specific architecture, although in the current work a neural architecture search will be adapted to (...) select the best ANN for estimating the relative motion. At the end, these ANNs will be compared with conventional algorithms to check the good performance of adopting an intelligent method for relative positioning estimation. (shrink)
