Development of the Polish Space Sector – Progression Barriers [PDF]

open access: yes, 2021
Sektor kosmiczny, ze względu na kapitałochłonność, wymaga poważnego zaangażowania finansowego. W polskich warunkach mogą je zapewnić przede wszystkim kontrakty przemysłowe z firmami zachodnimi, Europejską Agencją Kosmiczną lub granty ze środków ...

Constructing the space of valuations of a quasi-Polish space as a space of ideals

open access: yesCoRR, 2021
We construct the space of valuations on a quasi-Polish space in terms of the characterization of quasi-Polish spaces as spaces of ideals of a countable transitive relation. Our construction is closely related to domain theoretical work on the probabilistic powerdomain, and helps illustrate the connections between domain theory and quasi-Polish spaces ...

Defending biomedical authority and regulating the womb as social space. Prenatal testing in the Polish press [PDF]

open access: yes, 2010
The issue of abortion has been the topic of heated and frequent debate in post-Communist Poland. Parliamentary debate in 1998—9 centred around a legislative attempt to restrict prenatal testing, specifically amniocentesis, in order to further reduce the ...

Dimensionsgrad for locally connected Polish spaces [PDF]

open access: yesFundamenta Mathematicae, 2000
All spaces under discussion are separable and metrizable. Let \(A\) and \(B\) be disjoint subsets of a space \(X\). A closed set \(S\subseteq X\) is said to be a partition in \(X\) between \(A\) and \(B\) if there are open sets \(U\) and \(V\) in \(X\) such that \(A\subseteq U\), \(B\subseteq V\), \(X\smallsetminus S= U\cup V\), and \(U\cap V=\emptyset\

Determining and Evaluating the Hydrological Signal in Polar Motion Excitation from Gravity Field Models Obtained from Kinematic Orbits of LEO Satellites

open access: yesRemote Sensing, 2019
This study evaluates the gravity field solutions based on high-low satellite-to-satellite tracking (hl-SST) of low-Earth-orbit (LEO) satellites: GRACE, Swarm, TerraSAR-X, TanDEM-X, MetOp-A, MetOp-B, and Jason 2, by converting them into hydrological polar

Dispersion analysis of spaced antenna scintillation measurement [PDF]

open access: yesAnnales Geophysicae, 2009
We present a dispersion analysis of the phase of GPS signals received at high latitude. Basic theoretical aspects for spectral analysis of two-point measurement are given.

Time Distribution of Strong Seismic Events in the Fore-Sudetic Monocline in Context of Signals Registered by Water-Tube Gauges in Książ Geodynamic Laboratory

open access: yesSensors, 2021
Changes in the stress field in Świebodzice Depression (ŚU) unit area are the reason of complex kinematics of the rock blocks consisting of rotations and horizontal/vertical displacements.

Analysis of Large Geomagnetically Induced Currents During the 7–8 September 2017 Storm: Geoelectric Field Mapping

open access: yesSpace Weather, 2023
High temporal and high spatial resolution geoelectric field models of two Mäntsälä, Finnish pipeline geomagnetically induced current (GIC) intervals that occurred within the 7–8 September 2017 geomagnetic storm have been made.

Validation of GRACE and GRACE-FO Mascon Data for the Study of Polar Motion Excitation

open access: yesRemote Sensing, 2021
In this study, we calculate the hydrological plus cryospheric excitation of polar motion (hydrological plus cryospheric angular momentum, HAM/CAM) using mascon solutions based on observations from the Gravity Recovery and Climate Experiment (GRACE) and ...

POLISH SPACES OF BANACH SPACES: COMPLEXITY OF ISOMETRY AND ISOMORPHISM CLASSES

open access: yesJournal of the Institute of Mathematics of Jussieu, 2023
AbstractWe study the complexities of isometry and isomorphism classes of separable Banach spaces in the Polish spaces of Banach spaces, recently introduced and investigated by the authors in [14]. We obtain sharp results concerning the most classical separable Banach spaces.We prove that the infinite-dimensional separable Hilbert space is characterized
