Opis:
The health of individuals and societies depends on different factors including atmospheric conditions which influence humans in direct and indirect ways. The paper presents regional variability of some climate related diseases (CRD) in Poland: salmonellosis intoxications, Lyme boreliosis, skin cancers (morbidity and mortality), influenza, overcooling deaths, as well as respiratory and circulatory mortality. The research consisted of two stages: 1) statistical modelling basing on past data and 2) projections of CRD for three SRES scenarios of climate change (A1B, A2, B1) to the year 2100. Several simple and multiply regression models were found for the relationships between climate variables and CRD. The models were applied to project future levels of CRD. At the end of 21st century we must expect increase in: circulatory mortality, Lyme boreliosis infections and skin cancer morbidity and mortality. There is also projected decrease in: respiratory mortality, overcooling deaths and influenza infections.

Opis:
The paper presents a review of the conformal projections of a tri-axial ellipsoid and the methodology of creating these projections with the use of isometric coordinates. The concept is very simple and has been known for a long time; if isometric coordinates are introduced on the surface of the original and on the plane of the image, then any analytical function of the complex variable, i.e. a function that has a continuous derivative, creates a conformal projection. The introduction presents the history of conformal projections. Then, existing projections are presented, including the Bugayevskiy projection and several projections developed by the author that apply selected functions of the complex variable. Scripts were prepared in the Octave software with the use of the presented methodology. Programming in Octave ofers a possibility of a simple implementation of complex variable functions, which is also briefly discussed in the paper. The developed scripts were then used to perform calculations and to draw cartographic grids and distortion isolines in the selected conformal projections. The test object was the tri-axial ellipsoid that represents Phobos.

Opis:
Let \(Y \subset l^n_\infty\) be a subspace of codimension two. For \(n = 4\) the formula for cominimal projections will be presented. For \(n = 5\) the complete characterization of \(I\)-sets which determined cominimal projections and consequently the manner of finding cominimal projections will be given. This completes the results from [15].

On projections in the noncommutative 2-torus algebra
Autorzy:
Eckstein, Michał
Opis:
We investigate a set of functional equations defining a projection in the noncommutative 2-torus algebra $A_{\theta }$. The exact solutions of these provide various generalisations of the Powers-Rieffel projection. By identifying the corresponding $K_{0}(A_{\theta })$ classes we get an insight into the structure of projections in $A_{\theta}$.
