The use of the 90 dioptre fundus lens in conjunction with slit-lamp biomicroscopy as a method of estimating optic size was evaluated in a series of 37 patients. The measurements taken from the Haag-Streit slit-lamp were compared with values obtained planimetrically in order to assess a conversion factor and also the reliability of the method. This technique is a quick and easy method of obtaini...

In this lecture, the theoretical basis for the deterministic and statistical estimation of the lightning current from distant field measurements is presented. The influence of the presence of an elevated strike object on the peak of the lightning return stroke current determined from remote field measurements is also discussed.

Thirty-five available feeds were fermented in vitro in order to investigate their soluble total organic carbon (TOCs) and methane (CH4) production rate. A fermentation reactor was designed to capture the CH4 gas emitted and to collect liquor from the reactor during in vitro fermentation. The results showed that CH4 production rate greatly varied among feeds with different ingredients. The lowes...

We focus on the problem of adaptive estimation of signal singularities from indirect and noisy observations. A typical example of such a singularity is a discontinuity (change–point) of the signal or of its derivative. We develop a change–point estimator which adapts to the unknown smoothness of a nuisance deterministic component and to an unknown jump amplitude. We show that the proposed estim...

Due to its chronic nature with severe complications, diabetes needs costly prolonged treatment and care. The high economic burden of diabetes is particularly threatening low and middle income countries. Worldwide, studies have shown that the cost of diabetes per person is much higher than the per capita health expenditure. This study is the first to estimate the direct and indirect cost of diab...

In this paper we model linear inverse problems with long-range dependence by a fractional Gaussian noise model and study function estimation based on observations from the model. By using two wavelet-vaguelette decompositions, one for the inverse problem which simultaneously quasi-diagonalizes both the operator and the prior information and one for long-range dependence which decorrelates fract...

For many physical quantities, it is impossible or too costly to measure them directly. In such cases, we measure whatever quantities x1, ..., xn we can, and then we use the measurement results x̃1, ..., x̃n to estimate the value of the desired quantity y. Namely, as an estimate, we use ỹ = f(x̃1, ..., x̃n), where an algorithm f describes how the value y is related to xi. This procedure is called an...

In this paper, the modularized adaptive backstepping designs are incorporated into the recently proposed adaptive robust control framework to synthesize indirect adaptive robust controllers that achieve not only good output tracking performance but also better parameter estimation processes to obtain accurate parameter estimates for secondary purposes such as machine health monitoring and progn...
