Wola Justowska has long been thought of as the most attractive urban villa district of Krakow. A timber church from the XVI century that had originally been built in Komorowice Śląskie was relocated here in the year 1948, subsequently burning down a fire in 1978 in unknown circumstances. It had been rebuilt soon after, only to be set on fire a second time in 2002. After discussing numerous ideas and locations of its reconstruction, the design team developed a final version of its design, which featured the reconstruction of the church in its original location – in accordance with the will of the residents of Wola – which had been preceded by appropriate landscape analyses. The design calls for the reconstruction of the timber church in a slightly modified manner and placing it upon a concrete plinth, which is to be partially sheltered by the varied terrain around it. The aim of this idea was similar to that of the initial reconstruction, namely, to reconcile the form of the historical building that is to be reconstructed with the modern needs of the parish.

Conservation of the Old Town Zamość began to realize almost a hundred years ago. Then the eminent preachers of culture in the early period. 20.year inter-made idea of restoring the prestige of the works of Polish culture. The idea of protecting national cultural heritage grew gradually until such time as the first scientific research, development of standards and principles of care and maintenance. Today Zamość was inscribed on the UNESCO World Cultural Heritage. Many things made, much remains to be done.

The problem of reconstructing an unknown disturbance under measuring a part of phase coordinates of a system of linear differential equations is considered. Solving algorithm is designed. The algorithm is based on the combination of ideas from the theory of dynamical inversion and the theory of guaranteed control. The algorithm consists of two blocks: the block of dynamical reconstruction of unmeasured coordinates and the block of dynamical reconstruction of an input.

We present here a few thoughts regarding topological aspects of transferring a signal of a continuous time into its discrete counterpart and recovering an analog signal from its discrete-time equivalent. In our view, the observations presented here highlight the essence of the above transformations. Moreover, they enable deeper understanding of the reconstruction formula and of the sampling theorem. We also interpret here these two borderline cases that are associated with a time quantization step going to zero, on the one hand, and approaching its greatest value provided by the sampling theorem, on the other

In the research on historic, composed green areas various computer technologies are applied, including among others reconstruction ideograms and virtual spatial models. They are created on the basis of historical cartographic materials, among which Prussian maps Urmesstichblatts and Messtischblatts deserve special attention as they provide extraordinarily useful and often otherwise unavailable information concerning the system of spatial composition.

The article presents a method of procedure on the example of selected research objects. Such studies are extremely useful in the process of research, analyses and documentation of the authentic state of historical sites. Moreover, they provide a significant material for further analyses concerning revalorisation and creation of the cultural landscape.

The techniques of photogrammetric reconstruction were compared to the laser scanning in the article. The different conditions and constraints were introduced for reconstructed images, e.g. different materials, lighting condition, camera resolution, number of images in the sequence or using a-pripori calibration. The authors compare the results of surface reconstruction using software tools avaliable for photogrammetric reconstruction. The analysis is preformed for the selected objects with regard to laserscanned models or mathematical models.

The paper describes an innovative ultrasound imaging method called Doppler Tomography (DT), otherwise known as Continuous Wave Ultrasonic Tomography (CWUT). Thanks to this method, it is possible to image the tissue cross-section in vivo using a simple two-transducer ultrasonic probe and using the Doppler effect. It should be noted that DT significantly differs from the conventional ultrasound Doppler method of measuring blood flow velocity. The main difference is that when measuring blood flow, we receive information with an image of the velocity distribution in a given blood vessel (Nowicki, 1995), while DT allows us to obtain a cross-sectional image of stationary tissue structure. In the conventional method, the probe remains stationary, while in the DT method, the probe moves and the examined tissue remains stationary.

This paper presents a method of image reconstruction using the DT method. First, the basic principle of correlation of generated Doppler frequencies with the location of inclusions from which they originate is explained. Then the exact process and algorithm in this method are presented. Finally, the impact of several key parameters on imaging quality is examined. As a result, the conclusions of the research allow to improve the image reconstruction process using the DT method.

Assessment of the state of a pulse power supply requires effective and accurate methods to measure and reconstruct the tracking error. This paper proposes a tracking error measurement method for a digital pulse power supply. A de-noising algorithm based on Empirical Mode Decomposition (EMD) is used to analyse the energy of each Intrinsic Mode Function (IMF) component, identify the turning point of energy, and reconstruct the signal to obtain the accurate tracking error. The effectiveness of this EMD method is demonstrated by simulation and actual measurement. Simulation was used to compare the performance of time domain filtering, wavelet threshold de-noising, and the EMD de-noising algorithm. In practical use, the feedback of current on the prototype of the power supply is sampled and analysed as experimental data.

In 1875 a steel railway bridge was built in northern Warsaw. It had seven spans of 66.22 m and two spans of 15.24 m. In 1908 the second railway bridge was built downstream of the older one. The spacing of supports and spans were the same as in the older bridge. During World War I, both bridges were blown up and then rebuilt, first temporarily and then permanently. Again both were blown up in 1944. In 1945, a temporary crossing was built. In 1947 a permanent bridge was rebuilt, partially replacing rivets with welding. On the pillars of the older bridge, the Gdański Bridge was built (not in this study). In 1963 welded connections were strengthened, in 1980 the structure of the northern track was replaced. In 2016, the northern track was renovated. The replacement of the structure of the southern track is ongoing since 2018.

This paper presents a set of concepts aiming at the reconstruction of mechanisms of the development of economic space. These concepts are ordered in the way that consecutive concepts add new pieces of knowledge increasing the degree of cognition of the mechanisms of economic space. This set includes among others: shift from one steady-state to the next steady-states, selforganization and the development out of equilibrium, multiple equilibrium, punctuated equilibrium, innovation in the phase transition, pulsative course of development process, emergence of complex spatial systems, development code of the system of regions.
