The control of the current, position and shape of an elongated cross-section tokamak plasma is complicated by the instability of the plasma vertical position. In this case the control becomes a significant problem when saturation of the power supplies is c ...
Moire effects that occur in the superposition of aperiodic layers such as correlated random dot screens are known as Glass patterns. One of the most interesting properties of such moire effects, which clearly distinguish them from their periodic counterpar ...

State estimation is a widely used concept in the control community, and the literature mostly concentrates on the estimation of all states. However, in soft sensor problems, the emphasis is on estimating a few soft outputs as accurately as possible. The co ...
The two-way plot is a well-known tool to visualize the fit of a two-way table. An additive fit can be represented by two sets of parallel traces, whose intersection ordinates equal the fitted values. Based on linear traces, a variety of other two-way plots ...
Change detection plays a very important role in real-time image analysis, e.g., detection of intruders. One key issue is robustness to varying illumination conditions. We propose two techniques for change detection that have been developed to deal with var ...
The absorption spectrum of H2O in Ne, Ar, Kr, Xe and ice matrixes in the region of the 1st ~A 1B1 continuum is reported. Substantial blue gas-to-matrix shifts are obsd. for the max., which increase with decreasing matrix cage size. The absorption threshold ...
Reasons for the continuing difficulty in making definitive measurements of pulse wave attenuation in elastic tubes and arteries in the presence of reflections are sought. The measurement techniques available were re-examined in elastic tubes mimicking the ...
We analyze some queueing problems arising in guaranteed service and controlled load networks using min-plus algebra. We find an explicit representation for the sub-additive closure of the minimum of two operators, and we introduce a new, useful family of i ...
In this paper we describe the application of an H-infinity system identification procedure to a Tokamak. The work is motivated by the need to create linear models which are suitable for controller design and which may be used to validate different models d ...
