New and OriginalityThe project has proposed the simulation using Neural Networks methods, the genetic algorithm, analysis of clustering, to determine the "hidden" relations between physical-chemical parameters and magnetic characteristics and properties targets of magnetic nanomaterials. This approach is new and original. The parameters of performance are good: the method allows to obtain new information on some classes of nanomaterials. The use of a method which involves some statistical results is always at least at an acceptable level of performance and quality. Unfortunately so far it has conducted only a small number of tests to check the method. The quality of the solution seems to be good if we take into account the interest on strong reason project, expressed by numerous invitations received throughout the world for the publication of articles in specialist magazines and journals. Another positive signal is given by the high number of invitations to scientific events, on this issue, which come from the world. |
Implementation of the projectDuration of the project: 26 monthsWork Processing Period: 2006 1st of August - 2008 19 of SeptemberTotal value (lei): 1 475 000The project has had four phases of work and a final phase. Romania has been, on the conduct project cycle (September 2006 - September 2008) in a period of very intense cooperation with the majority of European countries and the USA, where research on the nanomagnetic material has known a continuous and substantial development. In these conditions were made numerous contacts of Romanians researchers participants in the project with researchers from the European Community and from other countries around the world, through participation in international scientific events abroad and in the country, with international participation. In these meetings was highlighted the relevant project aspects for current needs and existing constraints. At European level, there are at the beginning of this project (September 2006) a direction in the FP7, which is an issue close to the project (The source: MINOS EURONET (Micro-NanOSystem EUROpean NETwork) (http://www.minos-euro.net/index.htm)) During implementation, there has been consistent in time sequence of activities. In the greatest extent the compliance with the pattern of progress in the two-stroke was good, a disturbance occurred at the beginning of 2008 (for the last two stages). So that the same two stages has a spreading of only 8.6 months. There were no delays for activities and any interruption of activities. Activities were carried out while respecting the diagram of time. For the succession of activities, such as that e.g of the release, they have been harmonized with the current level of other activities in the period of time specified, without problems. The project has not proposed making a product of any kind, including computing. In accordance with the overall objective: the virtual design of new nanomagnetic materials with the help of High-performance computational techniques under the project have been proposed and implemented a number of: theoretical studies (8), systems (1), computer instrument (1) which have necessitated practically character activities, in the consortium partners laboratories. The project has approached by a new formula a complex problem of current sciences research, of physics of nanoscale magnetism and of the materials sciences: the study of magnetic properties in correlation with the conditions for preparation of magnetic nanomaterials. The results published of the greatest extent demonstrated project competitiveness for the integration programs and projects of joint research with similar entities at international level. |
ConclusionsKnowledge extracted using working instrument with ANN (Artificial Neural Networks) are still data, a large volume of data from exit, which are not easily accessible for human interpretation. The results are also to be processed. The results have been stored and analysed, interpreted by the partner's aid who have provided the first sets of entry data. After analysis of data, they could establish relations between size as characterizing composition and structure of these materials and their magnetic properties. On the nanomagnetic materials been studied one draw the following conclusions. Magnetic properties are dependent on : - nanosize dimension unit, the existence of critical size; - Mechanical processing; - Obtaining Conditions; - thermal, magnetic processes; Data correlation resulting from experimental measurements with the theoretical modelling magnetic domains at nanoscale units is still a difficult problem. For the full-scale nano-sizes must be formulated a theory of its own on magnetic domains specific for magnetic nanomaterials. |
