Abstract | In part 1 of the paper, the discrete model of a nonstationary heat flow process in the sample of material with a hot probe and an auxiliary thermometer based on a two-dimensional heat-conduction model was presented. To create the model the finite element method (FEM) implemented in the Matlab environment was used. The part two of the paper is concentrated on possibility of using a neural network for the thermal parameters determination. The artificial neural network (ANN) is used to estimate the coefficients of the inverse heat conduction problem for solid. The network determines the value of the effective thermal conductivity and the effective thermal diffusivity on the basis of temperature responses of the hot probe and the auxiliary thermometer. During selection of optimal ANN architecture several configurations were evaluated. The influence of measurands uncertainty on identified values of the thermal parameters was also analyzed. Training process and simulation analysis were conducted in the Matlab environment. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
