We describe an algorithm for computing points o = io < ii < • • • < xjt < Zfc+i = b which solve certain nonlinear systems d(z,_i,xt) = d(i,,x,+i), i = 1,... ,fc. In contrast to Newton-type methods, the algorithm converges when starting with arbitrary points. The method is applied to compute best piecewise polynomial approximations with free knots. The… (More)

The evaluation of the results of myocardial biopsy specimens of 24 patients highly suspected of having myocardial sarcoidosis revealed a sarcoid granuloma only in one case. In tapering frequency (60-33%) there has been myocardial scarring, generalized fibrosis, pathological count of mononuclear cells, nuclear hypertrophy, and perivascular fibrosis which all… (More)

A simple method for constructing almost interpolation sets in the case of existence of locally linearly independent systems of basis functions is presented. Various examples of such systems, including translates of box splines and nite-element splines, are considered.

This paper deals with interpolation and approximation satisfying constraints. We consider approximation by conditionally positive definite functions in norms which are associated with the conditionally positive definite functions. The theory of reproducing kernels is used to transform the approximation problems to quadratic optimization problems. Then we… (More)

Tracheobronchomegaly is a rare disorder. A marked dilatation of the trachea and the main stem bronchi is the characteristic sign measured as an enlarged transverse diameter (mean +/- 3 SD). Bronchiectasis is usual. In about one third of the published cases a diverticulosis was described as demonstrated in one our cases. For diagnostic modern radiological… (More)

In this paper we consider the problem of scattered data interpolation for multivariate functions. In order to solve this problem, linear combinations of products of positive definite kernel functions are used. The theory of reproducing kernels is applied. In particular, it follows from this theory that the interpolating functions are solutions of some… (More)

Previously Landis, Hunt, and PagC have reported that ultrarapid moving pictures show that the startle pattern, which is present in normal individuals following the sound of a revolver shot, is not present in many epileptics. In a group of 20 epileptics studied at Kings Park State Hospital, three showed an absence of all elements of the normal startle… (More)

Berichtet wird über einen 54-jährigen Mann mit chronischer rechtsbetonter Herzinsuffizienz. Echokardiographisch zeigte sich eine ausgeprägte Dilatation aller Herzhöhlen mit eingeschränkter links- und rechtsventrikulärer Pumpfunktion. Die Herzkatheteruntersuchung ergab eine hyperzirkulatorische Herzinsuffizienz infolge eines Links-rechts-Shunts durch eine… (More)

Structural tracheal stenoses have different functional effects according to degree, localization and extent of the stenosis. Further modifications are due to malacic components within the range of the stenosis or tracheal segments abutting on the stenosis. Nineteen patients with mainly cervical tracheal stenoses (12 patients) were investigated in order to… (More)
