In a rationing problem, a single homogeneous good is allocated among agents with possibly complex characteristics, or types. When types are single positive numbers (agents’ claims), Young’s theorem says that in the presence of continuity, a method of rationing is consistent and symmetric if and only if it can be represented by a continuous parametric… (More)
AIM Aim of this study was to assess concentrations of interleukin-6 (IL-6), interleukin-8 (IL-8) and interleukin-18 (IL-18) in the serum of newborns with diagnosed intrauterine growth restriction (IUGR) in comparison to concentrations in serum of newborns with weight appropriate for gestational age (AGA). MATERIALS Research was conducted at the Lodz… (More)
The purpose of this article is to present research into the inspection of software possibilities of using 8-bit Holter monitor in the study of cardiac arrhythmia (virulent ventricular arrhythmia) appearing in the T wave alternans. The first part of the article concentrates on the preparation of the ECG signal for the alternans analysis and the methods used… (More)
Modern Data Warehouses based on the OLAP model often require performing periodical analyses of data gathered in fact tables. In order to avoid recalculating the results every time new data arrives there is a need to create an organized results repository to store calculated values of every analysis.
This paper presents a decision support system that aims to estimate a patient׳s general condition and detect situations which pose an immediate danger to the patient׳s health or life. The use of this system might be especially important in places such as accident and emergency departments or admission wards, where a small medical team has to take care of… (More)
In modern business intelligence systems there is a need to reduce the data flow between operational transactional systems and data warehouses, as well as reduce the time between data update in the warehouse and reflecting this change in the analytical models used to perform business analyses. In a modern data warehouse with incremental data update, at every… (More)
This work presents the use of the finite differences method in thermal simulation. It introduces the method that speeds up calculations for dynamic simulations with non-linear boundary conditions. Two and three dimensional simulation for dynamic and static states are presented.
