  2. 6. Is it safe? safety factor reasoning in policy-making under uncertainty

    Author : Jonas Clausen Mork; John Cantwell; Stig Andur Pedersen; KTH; []
    Keywords : HUMANIORA; HUMANITIES; safety factor; uncertainty factor; uncertainty function; uncertainty; rationality; policy; decision; science; risk; Philosophy subjects; Filosofiämnen;

    Abstract : This thesis examines the practice of using safety factors in decision-making under uncertainty, in particular in the areas of toxicology and civil engineering. The aim is to expose and clarify some of the philosophical issues surrounding the practice. READ MORE

  4. 7. Resource Allocation under Uncertainty : Applications in Mobile Communications

    Author : Mathias Johansson; Anders Ahlén; Mikael Sternad; Vikram Krishnamurthy; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; resource allocation; uncertainty; probability theory as logic; scheduling; multiuser diversity; Jaynes; maximum entropy; Bayesian probability theory; Signalbehandling; Signal processing; Signalbehandling; Signal Processing; signalbehandling;

    Abstract : This thesis is concerned with scheduling the use of resources, or allocating resources, so as to meet future demands for the entities produced by the resources. We consider applications in mobile communications such as scheduling users' transmissions so that the amount of transmitted information is maximized, and scenarios in the manufacturing industry where the task is to distribute work among production units so as to minimize the number of missed orders.

  5. 8. Expectations, Uncertainty, and Monetary Policy

    Author : David Kjellberg; Annika Alexius; Nils Gottfries; Ulf Söderström; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Monetary Policy; Expectations; Uncertainty; Uncovered Interest Parity; Interest Rates; Economics; Nationalekonomi;

    Abstract : Essay 1 - To evaluate measures of expectations I examine and compare some of the most common methods for capturing expectations: the futures method which utilizes financial market prices, the VAR forecast method, and the survey method. I study average expectations on the Federal funds rate target, and the main findings can be summarized as follows: i) the survey measure and the futures measure are highly correlated; the correlation coefficient is 0.

  6. 9. Design flood estimation under uncertainty

    Author : Kenechukwu Okoli; Giuliano Di Baldassarre; András Bárdossy; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dimensionerande flöden; osäkerheter; avrinningsmodellering; frekvens analys.; Dimensionerande flöden; osäkerheter; avrinningsmodellering; frekvens analys.; Design flood; uncertainty; rainfall-runoff; frequency analysis.; Hydrology; Hydrologi;

    Abstract : Att bestämma dimensionerande flöden, d.v.s. sannolikheten för att vat-tenföringen i ett vattendrag överskrider ett givet värde, är ett allmänt hydrologiskt problem som exempelvis används för att utvärdera över-svämningsrisker i vattendrag samt för att dimensionera hydrauliska kon-struktioner.

  7. 10. Observational Uncertainties in Water-Resources Modelling in Central America : Methods for Uncertainty Estimation and Model Evaluation

    Author : Ida Westerberg; Sven Halldin; Jan Seibert; Lars-Christer Lundin; Chong-Yu Xu; Deliang Chen; Alberto Montanari; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Central America; Discharge; Flow-duration curve; Fuzzy regression; GLUE; Model evaluation; Non-stationarity; Observational uncertainty; Precipitation; Quality control; Rating curve; Regionalisation; Uncertainty estimation; Ungauged basins; Water resources; Avbördningskurva; Centralamerika; GLUE; icke-stationaritet; kvalitetskontroll; modellutvärdering; nederbörd; observationsosäkerheter; avrinningsområden utan vattenfö-ringsdata; oskarp regression; osäkerhetsuppskattning; regionalisering; varaktighetskurva; vattenföring; vattenresurser; Hydrology; Hydrologi; Hydrology; Hydrologi;

    Abstract : Knowledge about spatial and temporal variability of hydrological processes is central for sustainable water-resources management, and such knowledge is created from observational data. Hydrologic models are necessary for prediction for time periods and areas lacking data, but are affected by observational uncertainties. READ MORE
