The paper presents a geodetic method of controling the linearity of a trestle-crane runway placed in a steel structure. The authors disscussed the control measurements of diverse craines as well as the procedurę aimed at determining the deviations of track-beam axes from their design values. Moreover, they also analysed the deviations of the designed span of underrail track axes. The measurements were made using classical geodetic methods, and there were two of them -graphical and analytical - used to obtain the results. The graphical interpretation of the results is also presented.

Pearson Type Iii Distribution

In this paper the results are presented of estimation of T-year specific discharge of several streams in two regions in Slovakia. The Qmax time series used in the study were observed at water gauges from lowland Slovak part of the Morava River basin, and from the mountainous Belá River basin. For estimating the design values, we have studied the use of only one type of probability distribution, namely the Log-Pearson Type III Distribution (LP3 distribution). The use of only one type of distribution brings several benefits, e.g. possibility of the regionalization of the distribution parameters (in this study skew coefficient). In the first step the design values of the specific discharge series qmax (with historical data) were estimated and regional skew coefficients Gr of the LP3 distribution were computed. Regional skewness coefficient Gr was estimated to be 0.38 in the Morava River region, and 0.73 in the Belá River region. In many cases the estimate of the 1000-year specific discharge is two times higher than the value of the 100-year specific discharge. Then we have derived the empirical relations between station skew coefficient G and the elevation of the water gauge. In the second step we have derived the empirical relationships between 1000-years specific discharge q1000 and the elevation of the water gauge for both regions separately. The derived empirical regional equations can be used to estimate the 1000-years specific discharge of other streams in the region.

Abstract The article discusses a project that features the relocation of the historic Atelier building, built by Krakow-based architect Wandalin Beringer (1839–1923) who was active in the early twentieth century, and the regeneration of a plot belonging to the Congregation of the Resurrection since 1885, which is located at 12 Łobzowska Street in Krakow. The method includes cutting the entire structure off at the foundation and then after reinforcing it with a steel structure transporting it in its entirety to the new location. The project included two possible variants of moving the building in a straight line, either by 21 or 59 metres and evaluates two projects of further regeneration, the adaptive reuse of the building as an exhibition and religious space as well as a proposal for the remodelling of the nearby plot that belongs to the Congregation into a space for meditation and as a recreational park. The aim of these measures is to prevent the demolition of this building, now over a century old, as a result of which a forgotten element of the cultural heritage of the city will be saved. This project was based on the results of analyses of the cultural and historical conditions of Krakow. The block of buildings in which the Atelier in question is located is a very attractive location, near to the very centre of Krakow, adjacent to residential, service and educational buildings. It is directly adjacent to the Monastery Complex of the Congregation of the Resurrection, listed as a heritage building under conservation protection (municipal registry of heritage buildings). In the second half of the twentieth century, the building was used as a workroom by artists such as Xawery Dunikowski and later by the sculptress Teodora Stasiak. The case of the Atelier may provide an inspiration for discussion as well as raising awareness among citizens and city authorities to avoid future situations in which cultural heritage may become forgotten or demolished.
