Varningssystem behövs t.ex. vid intensivövervakning, smittskydd, miljörisker och kvalitetskontroll av vården. Statistiska varningssystem signalerar när det skett en väsentlig ändring och man vet vilka egenskaper systemet har. För varningssystem är det viktigt att larmet kommer snabbt...
has been simulated and optimized to reduce ion flight aberrations. A set of orthogonal two-dimensional polynomial … functions have been derived to reduce residual aberrations across a broad range of operating conditions. An upper limit to the …
Waterborne Cryptosporidium has been responsible for drinking water-associated disease outbreaks in a number of developed countries. As a result of the resistance of Cryptosporidium to chlorine, which is typically applied as a final barrier to protect the quality of distributed drinking water,...
Integer-valued autoregressive (INAR) time series form a very useful class of processes suitable to model time series of counts. In the common formulation of Du and Li (1991,JTSA), INAR models of order p share the autocorrelation structure with classical autoregressive time series. This fact...
In analysing time series of counts, the need to test for the presence of a dependence structure routinely arises. Suitable tests for this purpose are considered in this paper.
diseases but also in financial and other contexts. It is important to detect the onset of the outbreak as soon as possible to … allow timely action to be taken. New observations are made sequentially, and decisions whether the outbreak has started or … to ensure a quick and reliable detection. <p>In paper I, “Robust outbreak surveillance of epidemics in Sweden”, a semi …
Aims: Methods for prediction of the peak of the influenza from early observations are suggested. These predictions can be used for planning purposes. Methods: In this study, new robust methods are described and applied on weekly Swedish data on influenza-like illness (ILI) and weekly laboratory...
prevention, preparedness for, and management of a major animal disease emergency such as an FMD outbreak, asked the Productivity … Commission to report on the impact of a foot and mouth disease outbreak on Australia as an input to that process. The report … found that a major outbreak could cost Australia over $9 billion in lost export earnings over an eight year period and could …
