A high-precision pressure probe is described which allows non-invasive online-monitoring of the water relations of intact leaves. Real-time recording of the leaf water status occurred by data transfer to an Internet server. The leaf patch clamp pressure probe measures the attenuated pressure, P(p), of a leaf patch in response to a constant clamp pressure,(More)
The approach to solve the inverse problem of electrocardiography presented here is using a computer model of the individual heart of a patient. It is based on a 3D-MRI dataset. Electrophysiologically important tissue classes are incorporated using rules. Source distributions inside the heart are simulated using a cellular automaton. Finite Element Method is(More)
The effect of arbitrary mounting of maxillary casts on occlusal relationships was investigated in this study. Maxillary casts of 31 volunteers were mounted on an articulator by use of two split cast bases. This mounting was done first with the arbitrary face bow and second with a hinge bow. Three reference points were defined and measured on each maxillary(More)
In the present work the epicardial potential distribution for an individual patient provided by the solution of the linear inverse problem of electrocardiography are shown. To obtain the solution, the Twomey regularization as well as the stochastic regularization were used. Both methods require a priori estimations. These estimations were provided by means(More)
The penetration of coating pigments into the base paper is in clear contradiction to the goal of pigment coating which is to cover the base paper fibers. To determine its relevance and to obtain a better understanding of the influencing factors a proper characterization of the coating solids fraction penetrated the base paper is necessary. A high degree of(More)
Measurements of the diffuse reflection of various samples of softwood were made over the wavelength range 380-1040 nm to determine if certain types of defect, such as strains, can be distinguished by reasonably straight forward optoelectronic means. Healthy specimens of spruce, fir, and pine were tested, followed by specimens from the same wood species(More)
