After the Second World War, the Polish authorities were faced with the task of creating a land and building cadastre for a country whose territories had previously been covered by different legal systems. This task began with the issuing of relevant legal acts and regulations. They were all in textual form. Graphical notation appeared in Polish...

Architects have historically played an important role in kitchen designs, including notable female architects like Margarete Schütte-Lihotzky, author of the 1926 Frankfurt Kitchen. Their solutions resulted not only from practical needs, but also from social and cultural changes at the time. This was also the case in Poland, although this is less...

‘Zeitenwende’ as announced by German Chancellor Olaf Scholz in relation to Ukraine suggests the retrenchment of ‘territorialism’. I discuss this with a focus on Poland. Western Ukraine has after all been Eastern Poland until becoming part of the Ukrainian SSR in 1939. Enlarged with Crimea, the same SSR declared independence from the Soviet...

The thesis will elaborate Helena and Szymon Syrkus’ connection with the “Congress of Modern Architecture” (CIAM). It will investigate in what ways the Polish couple has brought Modernist ideas to Poland and put a special emphasis on the work of Helena Syrkus.<br/>The point of focus will lay on how the Helena Syrkus could manage to keep in touch...

The research looks at the role of architecture education in the female architects practising between 1930 and 1972 in Poland. It investigates not contested women's contribution to architecture development, as they are unquestionably underexplored and underappreciated. Women's participation in the construction of Polish cities remains a blank...

Aiming at a 5-DOF hybrid optical mirror polishing robot, the explicit dynamic model considering the joint friction is established and the inertia coupling distribution is studied. Firstly, the kinematics of the manipulator is solved based on closed-loop vector method, and the dynamic model is established with Newton-Euler method based on the...

The 3D cadastre model in Poland has been developed for several years. The summation of these works is the proposal of the model of the Polish cadastre developed using the UML language on the basis of the existing legal regulations, presented in detail in the work (Bydłosz and Bieda, 2020). The aim of the current research was practical...

Low calcium alkaline solution activated cement composite, or geopolymer concrete has been around for about 40 years. The main benefit of this material - it is partially made by utilising waste products, such as fly-ash, slags and others. It has been claimed that the manufacturing of various geopolymer binder produces up to 6 times less CO2 than...

The circular economy demands waste utilization for the production of high-value products, and this requires the development of novel processing routes. In this study, rare earth (La and Ce) oxides were completely (&gt;99%) recovered from polishing waste by a combined novel reductive acid leaching and alkali treatment process. About 70% of...

Polyurethane-bound porous mixture (PPM) is a new type of pavement material that has shown some potential for overcoming common asphalt mixtures mechanical failures. However, little research has been done on its skid resistance performance. This work presents a comparative study of the skid resistance development between PPM and asphalt...

The production of cement leads to a large amount of CO<sub>2</sub> emission. Using industrial waste slag, such as ceramic polishing powder (PP), to replace part of Portland cement can reduce the pollution caused by the cement industry and solid waste disposal. In order to use PP as a replacement for cement, its effects on the properties of...

One of the main applications of ceria (CeO <sub>2</sub> ) is its use in glass polishing. About 16,000 tonnes of rare earth oxides, which is about 10% of total rare earth production, are used for polishing applications. The waste generated in glass polishing contains rare earths, along with other impurities. In this study, two different glass...

Multi-junction solar cells are considered for various applications, as they tackle various loss mechanisms for single junction solar cells. These losses include thermalization and non-absorption below the band gap. In this work, a tandem configuration comprising copper-indium-gallium-di-selenide (CIGS) and hydrogenated amorphous silicon (a-Si...

Ceria is the main component in glass polishing powders due to its special physico-chemical properties. Glass polishing powder loses its polishing ability gradually during usage due to the accumulation of other compounds on the polishing powder or due to changes in the particle size distribution. The recovery of cerium from the glass polishing...

This master thesis investigates the effect of surface morphology of Selectively Laser Melted Ti-6Al-4V on fatigue performance. The literature study performed here iden- tifies roughness as one of three major causes for the decreased performance of the additive manufactured alloys (along side porosity and residual stresses). In order to eliminate...

The specific issue researched in this thesis is correcting some inaccuracies that occur when the robot is polishing<br/>certain shapes. The biggest challenge is to mathematically describe this phenomenon in order to find<br/>an appropriate correction. Since there are a lot of influences in the process (friction, movement, impact, degrees<br/>of...

The Polish cadastral model was finally defined (after modifications) in 2015, within the regulation of Ministry of Administration and Digitization. According to this legal act, cadastral model comprises information on land, buildings and premises (apartments) being independent estates. These data generally concern two dimensions, whereas chosen...

The meso-scale surface roughness of piezoelectric fiber composites can be manipulated by applying an electric field to a piezocomposite with a polished surface. In the absence of an applied voltage, the tips of the embedded piezoelectric ceramic fibers are below the surface of the piezocomposite and a silicon wafer counter surface rests solely...
