Reconstruction of nonlinear material properties for homogeneous, isotropic slabs using electromagnetic waves

This paper addresses the inverse problem of reconstructing a medium’s instantaneous, nonlinear response to electromagnetic excitation. Using reflection and transmission data for an almost arbitrary incident field on a homogeneous slab, we are able to obtain the nonlinear constitutive relations for both electric and magnetic fields, with virtually no assumptions made on the specific form of the rel

Exception Handling in S88 using Grafchart

Exception handling constitutes a large part of the design andimplementation effort in batch production, but so far little work hasbeen carried out to specify this area. This paper proposes an internalmodel approach for equipment unit supervision using Grafchart. It alsodiscusses exception handling at the recipe level.

On Evil Twins and Their Absent Friends

Popular Abstract in Swedish Kunskap om intermetalliska föreningar och legeringar är avgörande för tekniksprång. Den senaste av dessa, den så kallade digitala revolutionen, började perioden för informationsåldern som kännetecknas av snabb informationsöverföring. Den ständiga utvecklingen av snabbare och mindre elektroniska apparater kommer med nackdelen av ökade mängder avfall, vilket innebär produKnowledge on intermetallic compounds and alloys is essential for technology leaps. The latest of these, the so-called digital revolution, started the period of the information age which is characterized by fast information transfer. The constant development of faster and smaller electronic devices comes with the drawback of increased amounts of waste, meaning products that used to by high-end tech

LQG Control Over a Markov Communication Network

We formulate and solve a control problem where data are sent over a communication network that introduces random time delays. Past time delays are assumed known by the use of timestamps and the probability distribution of future delays are modeled with a Markov chain with continuous observation densities. We generalize previous results on LQG control of jump linear systems to cover this situation.
