The coadjoint orbit method is applied to the construction of Hamiltonian dynamics of massless particles of arbitrary helicity. The unusual transformation properties of canonical variables are interpreted in terms of nonlinear ...
The Carbon Footprint Methodology in CFOOD Project
Stawska, Zofia ; ; Milczarski, Piotr ; Hłobaż, Artur ; ; (Polish Academy of Sciences Committee of Electronics and Telecommunications, 2020)
; ; Milczarski, Piotr ; Hłobaż, Artur ; ; (Polish Academy of Sciences Committee of Electronics and Telecommunications, 2020)
In the paper, the research on the process of
optimizing the carbon footprint to obtain the low-carbon
products is presented. The optimization process and limits were
analyzed based on the CFOOD project co-financed by ...
Modalities for an Allegorical Conceptual Data Model
Zielinski, Bartosz ; ; (MDPI AG, 2014)
; ; (MDPI AG, 2014)
Allegories are enriched categories generalizing a category of sets and binary relations. In this paper, we extend a new, recently-introduced conceptual data model based on allegories by adding support for modal operators ...
Weak n-Ary Relational Products in Allegories
Zielinski, Bartosz ; (MDPI AG, 2014)
; (MDPI AG, 2014)
Allegories are enriched categories generalizing a category of sets and binary relations. Accordingly, relational products in an allegory can be viewed as a generalization of Cartesian products. There are several definitions ...
