Document binarization is an active research area for many years. The choice of the most appropriate binarization algorithm for each case proved to be a very difficult procedure itself. In this paper, we propose a new technique for the validation of document binarization algorithms. Our method is simple in its implementation and can be performed on any binarization algorithm since it doesn’t req...

An enduring problem in electoral systems is that of "disproportionality," i.e., the mismatch between a party's percentage of the popular vote and its percentage of legislative seats. Such disproportionality is quite common and extreme cases are easy to find in the real word. To give just one example, the Liberal Party in Britain polled 13.8% of the national vote in 1979 but was rewarded with on...

One of the most challenging problems in small molecule activation is the development of a homogeneous catalyst for converting dinitrogen into ammonia at ambient temperatures and atmospheric pressure. A catalytic cycle based on molybdenum that converts dinitrogen into ammonia has been reported. However, a well defined iron based system for the conversion of dinitrogen into ammonia or hydrazine h...

This paper describes how the K(alpha)/K(beta) count rate ratio of the characteristic X-rays of a given element can be applied to determine the depth at which a layer or a grain of that element is located. The theoretical background and a basic description of the K(alpha)/K(beta) technique are given in the introduction. The experimental part of the paper deals with measurements of thick standard...

The independent association between the indices of iron stores or administered intravenous iron, both of which vary over time, and survival in patients who are on maintenance hemodialysis (MHD) is not clear. It was hypothesized that the observed associations between moderately high levels of three iron markers (serum ferritin, iron, and iron saturation ratio) or administered intravenous iron an...

This paper addresses a special problem with historical document images where handwritten characters from the reverse side appear as noise on the front side and even interfere with the front side characters. A novel method to extract clear textual images from interfering and overlapping areas of text is presented here. The proposed algorithm is interesting in that, with an observation that the e...

We describe ongoing work aiming at deriving a multilingual controlled vocabulary (German, French, Italian) from the combined subject indices from 22 volumes of a large-scale critical edition of historical documents. The controlled vocabulary is intended to support editors in assigning descriptors to new documents and to support users in retrieving documents of interest regardless of the spellin...
