  abstract	= {In many applications, for example in heat diffusion and in
		  flow problems, it is important to describe the process
		  behavior inside the particular medium. An example can be
		  the strive for estimating certain parameters related to the
		  material. This paper describes how the diffusion, modeled
		  by a partial differential equation, can be solved using
		  numerical methods and how results from the field of system
		  identification can be utilized in order to estimate the
		  parameters of interest.}
