Opis:
The paper is intended to describe a method for the calculation of 3D viscous compressible (subsonic or supersonic) flow in axial turbomachines described in the form of thin-layer Reynolds-averaged Navier-Stokes equations. The method draws on Godunov-type upwind differencing and ENO reconstruction suggested by Harten (1987), so as to assure monotonicity preservation and high accuracy of computational results. The computational efficiency is achieved thanks to the implementation of a simplified H-type multi-grid approach and delta -form implicit step. Turbulent effects are simulated with the help of a modified algebraic model of Baldwin-Lomax (1978). This method was at the foundation of a computer code-a complex software package to calculate 3D flow in multi-stage turbomachines that allows us to obtain local characteristics, like temperature, pressure, density or velocity distributions, as well as global characteristics, such as flow rates, stage reaction, flow efficiency for the considered turbine/compressor stage. The paper also gives selected results of computation of a number of turbomachinery cascades, showing that these results agree reasonably well with the available experimental data.

Opis:
The process of cliff erosion in Jastrzrtbia G6ra is a superposition of two phenomena: the abrasion at the foot of the cliff and slope failures of its upper part. Prior to the reconstruction works the stability analysis was done. Obtained results clearly documented reasons of slope failures observed during years. Based on the results five methods of slope protection were discussed The chosen method for reconstruction of a one cliffs stretch consists of a drainage system installation and slope support by means of reinforced sand blocks. During construction works the emergency laser system at the edge of the cliff was installed The construction works were successfUlly completed in the middle of November 2000.

Opis:
The thickness correction resulting from gravitational compaction is one of the significant parameters in the reproduction of the palaeothickness of sedimentary complexes in palaeotectonic reconstructions. Changes of sediment thickness during burial caused by compaction are taken into account in the calculation of a thickness correction. The reconstruction of the layer thickness may be based on a quantitative interpretation of absolute porosity changes. Here, an original method of introducing a compacted thickness correction is developed in which two components, a syn-genetic one and a post-genetic one, are separated and the continuous process of compaction during the burial of sediments is taken into account. The proposed approach is simple; however, a detailed determination of the palaeothickness of the layers during their burial involves computer calculations. In this paper the method is described and the computation algorithm is given. Some results of modelling and computations carried out for real data from the eastern part of the Polish Carpathians and Pomeranian Swell are also given. Examples illustrate changes in the recent thickness of layers after introducing the compaction correction.

Opis:
The joint network in the portion of the Dukla Nappe studied originated in two stages showing different orientations of the stress field axes. The older, compressive stage I was characterised by a N45°E-orientated (at present coordinates) horizontal s1, and formation of the diagonal, shear (SL and SR) joint system. The younger, extensional stage II was characterised by vertical s1 and horizontal, N35°E-orientated (also at present coordinates) s3, suitable for formation of the fold-parallel joints. At the turn of the first stage, under diminishing horizontal compression (s1 trending N35°E), the cross-fold T joints developed. The orientation of the maximum compression axis changed between stages I and II. The first stage probably commenced while strata which were not fully lithified underwent shortening, and lasted until the termination of nappe emplacement. The second stage, in turn, is associated with post-orogenic collapse of the Carpathians, whose onset in the study region began at least in Late Miocene times.

Opis:
A problem of reconstruction of a non-observable control input for a system with a time delay is analyzed within the framework of the dynamical input reconstruction approach (see Kryazhimskii and Osipov, 1987; Osipov and Kryazhimskii, 1995; Osipov et al., 1991). In (Maksimov, 1987; 1988) methods of dynamical input reconstruction were described for delay systems with fully observable states. The present paper provides an input reconstruction algorithm for partially observable systems. The algorithm is robust to the observation perturbations.

Opis:
The aim is to reconstruct a signal function x ∈ L₂ if the phase of the Fourier transform [x̂] and some additional a-priori information of convex type are known. The problem can be described as a convex feasibility problem. We solve this problem by different Fejér monotone iterative methods comparing the results and discussing the choice of relaxation parameters. Since the a-priori information is partly related to the spectral space the Fourier transform and its inverse have to be applied in each iterative step numerically realized by FFT techniques. The computation uses MATLAB routines.

Opis:
Basing on analysis of tectonic mesostructures, the structural evolution stages of the Gnieździska Syncline have been determined. The structure represents a typical example of folds occurring in the SW margin of the Holy Cross Mountains. The well-exposed syncline displays a wide variety of structures, including: shear and extension joints, stylolites, cleavage, strike-slip and dip-slip faults as well as master joints. Tectonic structures resulting from flexural slip indicate that the Gnieździska Syncline developed as a flexural-slip fold as a result of horizontal NE-SW compression. The subsequent deformation phase included mesostructures pointing to the increasing activity of a nearby Gnieździska-Wola Morawiecka dextral strike-slip fault of regional extent. In the terminal phase of the post-kinematic uplift of the Holy Cross Mountains, T joints and master joints appeared.

A system oriented to develop an image processing system, which takes advantage of radiation flashes from a plasma focus, by optimizing the emission-detection-reconstruction procedure, is presented. A computer technique for 3D reconstructions was combined with radiographic images of objects X-rayed with a compact plasma focus. The technique is able to automatically determine the position of the rotation axis, reconstruct the 3D-attenuation map, and display inner cuts. The system was demonstrated in introspective tomographic imaging of a stainless steel BNC elbow.

Opis:
Specimens of the microscopic teeth of the chondrichthyan genus Thrinacodus are described from Mississippian (Tournaisian) rocks of Ireland. They are from calcareous mudstones or crinoidal limestones whose palaeoenvironments are interpreted as ranging from near shore, shallow water through moderately shallow high energy carbonate shelf, to relatively deep off−shore. The richest fauna was recovered from the high−energy carbonate shelf, containing both asymmetrical and symmetrical teeth raising the possibility that they may have been derived from a single species of shark. The teeth are assigned to Thrinacodus incurvus (Newberry and Worthen, 1866), which is suggested to be a senior synonym of Thrinacodus ferox Turner, 1982. Presently the genus is known only from isolated teeth. The asymmetrical and symmetrical teeth are described as two morphotypes, ferox morphotype and nanus morphotype. Within the morphotypes, morphological variation occurs, especially within the ferox morphotype, allowing a number of possible reconstructions of the dentition of Thrinacodus incurvus to be presented as a basis for future debate.

W artykule przedstawiono przebieg prac mających na celu wykonanie przestrzennej rekonstrukcji nieistniejącej już budowli, jaką był Odwach na Rynku Głównym w Krakowie. Archiwalnym materiałem fotograficznym, na którym bazowała rekonstrukcja było siedem zdjęć wykonanych nieznanymi kamerami fotograficznymi. Dla rozwiązania zagadnienia – obliczenia przestrzennych współrzędnych wybranych punktów budowli, wykorzystano metodę DLT. Dla porównania współrzędne punktów rekonstruowanej budowli obliczono niezależnie wykorzystując system obliczeniowy ORIENT. Po uzyskaniu odpowiedniej liczby punktów budowli, dla uzyskania efektu fotorealistycznego, skonstruowano w MicroStation95 jej model wire frame, który pokryto rastrem ze zdjęć.
The purpose of research presented in this paper was to obtain a 3D photogrammetric reconstruction of non-existing architectural object – Odwach on Main Market in Cracow. This reconstruction was based on seven archival images, made with unknown photographic cameras. To solve this problem, which was calculation of coordinates of building points, the DLT method with AEROSYS was used. The bundle method with ORIENT was applied for comparison. After obtainment of proper number of building points, its wire frame model was constructed with using of MicroStationSE software. The wire frame was rendered by samples of archival images for obtain a photorealistic object visualization.

The aim of this paper is to study regional gradient observability for a diffusion system and the reconstruction of the state gradient without the knowledge of the state. First, we give definitions and characterizations of these new concepts and establish necessary conditions for the sensor structure in order to obtain regional gradient observability. We also explore an approach which allows for a regional gradient reconstruction. The developed method is original and leads to a numerical algorithm illustrated by simulations.

Opis:
Statistic analysis of the bed orientation in the Magura and Silesian Nappes was performed in order to establish the directions of regional fold axes. On this ground, variations of the main horizontal stress directions were inferred for both nappes. In the Late Oligocene, in the foreland of the northwards moving Adriatic Microplate, a fan-like pattern of the 1 stress trajectories was formed. Initiation of the Magura Nappe and the related regional folds began in such conditions. Evolution of the regional compression involved clockwise rotation from S-N to SW-NE direction. The rotation was caused by the Early Miocene oblique collision of the Carpathian Orogen with the East European Platform. The pattern of fold axes in the Silesian Nappe reflects this rotation.
