  1. 1. A Non-Stationary perspective on the European and Swedish Business Cycle

    University dissertation from Department of Economics, School of Business, Economics and Law, Göteborg University

    Author : Louise Holm; Högskolan i Skövde.; Göteborgs universitet.; Gothenburg University.; [2007]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SOCIAL SCIENCES Business and economics; SAMHÄLLSVETENSKAP Ekonomi; Humanities and Social sciences; Humaniora-samhällsvetenskap; Business cycles; business cycle dating; non-parametric smoothing; non-stationarity; recession prediction; interest rate spread; binary respons models; Business cycles; business cycle dating; non-parametric smoothing; non-stationarity; recession prediction; interest rate spread; binary response models.;

    Abstract : Business cycles, the ups and downs observed somewhat simultaneously in numerous macroeconomic variables in an economy and often measured using real GDP, are important and, despite much economic research, still incom- pletely understood. Dating the business cycle has always been of interest in macroeconomic research. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ida Westerberg; Uppsala universitet.; [2011]
    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; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Hydrology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap 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

  4. 4. Ion dynamics and structure of collisionless shocks

    University dissertation from Uppsala University

    Author : Andreas Johlander; Uppsala universitet.; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Shock waves are responsible for slowing down and heating supersonic flows. In collisionless space plasmas, shocks are able to accelerate particles to very high energies. We study injection of suprathermal ions at Earth’s quasi- parallel shock using high time resolution data from the Cluster spacecraft. READ MORE

  5. 5. Stochastic Modeling and Management of an Emergency Call Center A Case Study at the Swedish Emergency CallCenter Provider, SOS Alarm Sverige AB

    University dissertation from Sundsvall : Mid Sweden University

    Author : Klas Gustavsson; Mittuniversitetet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Call Center Management; Burst Modeling; Stochastic Resources; Skills-Based Routing; Discrete-Event-Simulation;

    Abstract : A key task of managing an inbound call center is in estimating its performance and consequently plan its capacity, which can be considered a complex task since several system variables are stochastic. These issues are highly crucial for certain time-sensitive services, such as emergency call services. READ MORE
