Decoherence-free communication over multiaccess quantum channels
PublicationIn this paper we consider decoherence-free communication over multiple access and k-user quantum channels. First, we concentrate on a hermitian unitary noise model U for a two-access bi-unitary channel and show that in this case a decoherence-free code exists if the space of Schmidt matrices of an eigensubspace of U exhibits certain properties of decomposability. Then, we show that our technique is also applicable for generic random unitary...

Styrene epoxidation over heterogeneous manganese(III) complexes
PublicationThe manganes(III) complex functionalised with 2,3-dihydropyridazine has been encapsulated in the supercages of the NaY zeolite using two different procedures, flexible ligand and in situ complex. The parent zeolite and the encapsulated manganese(III) complexes were screened as catalysts for styrene oxidation by using t-BOOH as the oxygen source in acetonitrile. Under the optimized conditions, the catalysts exhibited moderate activity...

Redundant Actuation of 3RRR over-actuated Planar Parallel Manipulator
PublicationPraca opisuje zagadnienia modelowania i napędzania manipulatorów równoległych. Cechą charakterystyczną manipulatorów równoległych jest występowanie jednego lub kilku łańcuchów kinematycznych zamkniętych (gałęzi równoległych). Standardowo, konstrukcje takie są napędzane jedynie silnikami montowanymi w parach kinematycznych łączących łańcuchy kinematyczne z podstawą. Niekiedy konstrukcje takie są układami napędzanymi nadmiarowo (liczba...

Unconditional privacy over channels which cannot convey quantum information
PublicationQuantum cryptography enables one to verify that the state of the quantum system has not been tampered with and thus one can obtain privacy regardless of the power of the eavesdropper. All previous protocols relied on the ability to faithfully send quantum states or equivalently to share pure entanglement. Here we show this need not be the case-one can obtain verifiable privacy even through some channels which cannot be used to...

CHANGES TAKING PLACE IN THE KINETIC ARCHITECTURE OVER THE 20TH AND 21ST CENTURIES
PublicationKinematics has accompanied architecture from its beginning and is strongly associated with its evolution. Over the centuries, it has changed form and function. However, its rank grew at the beginning of the 20th century. Along with the widespread change of the design method in the early 90s of the twentieth century, its forms have become more complex. The study showed that with the development of design techniques, this time should be...

Technological and Media Platforms: Redefinition of Meanings as Symbolic Power over the Discourse
PublicationRedefining the meanings of such social terms as “likes” and “friends” on Facebook is a popular practice. In terms of consistency, the (auto)-redefinition of the term “platform” is itself particularly important from a media management perspective. The article proposes to consider the redefinition of meanings as a form of wielding non-transparent power over discourse. From this perspective, redefining a meaning is a form of holding...
