Bestämning av parametrar i dynamisk modell för insulinsvar på glykoslast

Quantification of parameters of a simple dynamic glucose-insulin model was performed. Measured data from seven test subjects were used. The Model was simulated by SIMNON and optimized by OPTA. The results are presented and their validity are discussed. Some problems when using OPTA are given account for.

Generella beräkningar på mätdata

This report describes an interactive program which performs computations on data files. The basic idea is that the user describes the computations by writing statements (similar to SIMNON statements) in a file. These statements are compiled and a pseudo code is created. By interpreting this code the program can perform the computations. The program is run by entering commands from a teletype. The

Logical control of a model railway is presented. The model railway is controlled by a PDP 8/s minicomputer. By energizing tracksections and switching turnouts the trains can be controlled.

Simulering av produktionssystem

The purpose of this report has been to find suitable methods and programs for simulation, in particular of production flow systems. Only few methods of this subject have been developed, and therefore a considerable time has been used to find the basic facts. The problem has been attacked with two different methods. The first one is a simulation program which has all decision rules mathematically d

The Hodkin-Huxley Model Applied to Low Frequency Repetetive Firing Nerves

Membranpotentialen hos en cell härledes som en funktion av membranens selektiva permeabilitet och koncentrationsgradienter över membranen. Hodkin-Huxleys nervmodell introduceras och med hjälp av digital simulering visas att den inte kan beskriva en lågfrekvent fyrande nerv. Enkla moditiferingar med bibehållen tolkning av ekvationerna ger en mer realistisk modell. Den modifierade modellen analysera

Jämförelse av olika dynamiska modeller för sedimenteringen i biologisk vattenredning

Different models of the solids-liquid separation in an activated sludge system are presented. The influence from the solids-liquid separator on the biological activities in the aeration tank is examined. The dynamics of the different separator models is discussed. Two simple control strategies for sludge removal has been tried out.
