  2. 16. Modelling and Simulation of Dynamic Behaviour in Crushing Plants

    Author : Gauti Asbjörnsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Crushing; Dynamic Simulation; Modelling; Screening;

    Abstract : Crushing plants are a vital part in the production of aggregates and metals. Plants are traditionally simulated with a steady-state simulation. With steady-state simulation the plant is simulated until equilibrium is achieved. READ MORE

  4. 17. Bayesian Sequential Inference for Dynamic Regression Models

    Author : Parfait Munezero; Mattias Villani; Helga Wagner; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Bayesian sequential inference; Dynamic regression models; Particle filter; Online prediction; Particle smoothing; Linear Bayes; Statistics; statistik;

    Abstract : Many processes evolve over time and statistical models need to be adaptive to change. This thesis proposes flexible models and statistical methods for inference about a data generating process that varies over time. The models considered are quite general dynamic predictive models with parameters linked to a set of covariates via link functions. READ MORE

  5. 18. Dynamic Matrix Algorithms and Applications in Convex and Combinatorial Optimization

    Author : Jan van den Brand; Danupon Na Nongkai; Santosh Vempala; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dynamic Algorithm; Data Structure; Optimization; Linear Program; Bipartite Matching; Shortest Path; Maximum Flow; Minimum Cost Flow; Diameter; Computer Science; Datalogi;

    Abstract : Dynamic algorithms are used to efficiently maintain solutions to problems where the input undergoes some changes.This thesis studies dynamic algorithms that maintain solutions to linear algebra problems and we explore their applications and implications for dynamic graphs and optimization problems.

  6. 19. Ventricular Depolarization in Ischemic Heart Disease.Value of Electrocardiography in Assessment of Severity and Extent of Acute Myocardial Ischemia

    Author : Michael Ringborn; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute myocardial ischemia; Acute myocardial infarction; Severity of ischemia; QRS changes; HF-QRS; QRS slopes; Depolarization changes; Myocardium at risk; Final infarct size; SPECT.;

    Abstract : Background In patients with symptoms compatible with acute myocardial infarction (MI), early triage by ECG in the pre-hospital phase by ST-segment elevation myocardial infarction (STEMI) criteria is important for direct transport of these patients to a regional center for primary percutaneous coronary intervention (pPCI). The time from first medical contact to pPCI should, due to present guidelines, be no longer than two hours. READ MORE

  7. 20. Chinese educational policy : changes and contradictions 1949-79

    Author : Jan-Ingvar Löfstedt; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Utbildningspolitik; Kina;

    Abstract : The purpose of this study is to examine educational policy in the People's Republic of China over a 30 year period. Educational policy-making is seen as a dynamic process related to (1) the general socio-economic context, (2) Marxist educational theory, (3) the Chinese development strategy, and (4) Soviet experiences.
