Analiza wrażliwościowa wyznaczanego optymalizacyjnie klirensu komórkowego w modelu dwuprzedziałowym
(Wydawnictwa AGH, 2006) Korohoda, Przemysław
The paper considers the kinetic urea modelling, a tool used in the haemodialysis treatment. The efforts to introduce the two-compartmental model to the practical applications are mitigated by the lack of numerical value for the cellular clearance, Kc, being the crucial parameter of this model. The optimisation procedure, utilising the adjusted model technique to assess the Kc value, should be applied with the knowledge about relevant sensitivity of the resulting values to the changes in the input parameters. The changes that result from the inevitable measurement errors. In the paper a method of evaluating the required sensitivity values is described and a computational example based on the typical values is provided. The obtained results may be used to indicate the input parameters which must be measured with particular care. Application of the described procedure should provide arguments to recognise if the differences between the obtained Kc values result from inaccuracy of the input values or indicate the important phenomena.
Model populacji dziecięcej do weryfikacji metod analizy bioimpedancyjnej
(Wydawnictwa AGH, 2006) Korohoda, Przemysław
A model for simulation of the measurement data obtained for statistical samples of healthy children population is proposed. The model in its future version should be suitable to investigate methods used in the area of the bioimpedance analysis to compute the total body water volume and the external compartment volume in the dialysed paediatric patients. The introductory version of model, which is based on combined deterministic and random formulas, has been positively verified with use of the available reference data.
Mobilny system zdalnego nadzoru kardiologicznego: aspekty implementacyjno-techniczne
(Wydawnictwa AGH, 2006) Mikrut, Zbigniew; Augustyniak, Piotr
The paper presents a concept and realization of a cardiologic monitoring system, which analyzes in real time the ECG signal from Holter recorder and transmits the results of the analysis to the supervising center. Strips of the original ECG signal are transmitted only in cases when irregular heart action (heart malfunction) is detected. The connection layer used in the prototype is the GSM cellular network, namely the GPRS transmission, sending SMS text messages and - only in emergency cases - direct modem connection CSD. In the paper the implementation and testing results are described for both the client application (software on the patient's end) and the server software (the application responsible for setting-up the connections and transferring the acquired data to the MySQL database and Apache server).
Automatyczna ocena zaburzeń emisji głosu będących wynikiem procesów neurodegeneracyjnych w oparciu o analizę wyizolowanych głosek
(Wydawnictwa AGH, 2006) Orzechowski, Tomasz Stanisław; Chmurzyńska, Katarzyna; Radkowski, Piotr
This paper presents results of preliminary research of voice pathological changes caused by dysarthria. Computer analysis of voice may lead to identification of parameters correlated with neurological diseases. The selection of linguistic material was characterized according to the place and manner of articulation in the phonetic system of Polish. Results of clinical examination allowed to determine simple markers of neurodegenerative diseases, which will serve as a basis for construction of objective examination model.
Modelowanie chemotaksji w populacji komórek przy użyciu metod multiagentowych
(Wydawnictwa AGH, 2006) Wołoszyn, Paweł
Biochemical signals produced by colony of unicellular organisms can induce complex movements of cells caused by their chemotaxis. This behaviour can be modelled with the use of multiagent dynamic system. This paper describes multiagent model of a cellular colony and presents the results of performed simulations, which reveal agents' spontaneous tendency to aggregate into clusters. Analysis of model dynamics leads to conclusion that apparently intentional behaviour can emerge in population consisted of simple agents lacking ability to make strategic decisions.
