  2. 1. Mathematics at work : a study of mathematical organisations in Rwandan workplaces and educational settings

    Author : Marcel Gahamanyi; Ingrid Andersson; Christer Bergsten; Linköpings universitet; []
    Keywords : Workplace mathematics; school mathematics; activity theory; anthropological theory of didactics; mathematical organisation; didactic transposition; contextualised mathematical tasks.; Skolmatematik; arbetsplatsmatematik; aktivitetsteori; antropologisk didaktisk teori; matematisk organisation; didaktisk transposition; kontextualiserade uppgifter; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : To make mathematics more significant for the beneficiaries, the problem studied in this thesis is to investigate how to connect mathematical daily practices with educational contexts. The overarching aim is to investigate how to contextualise school mathematics within Rwandan cultural mathematics practices. READ MORE

  4. 2. A pseudoparabolic reaction-diffusion-mechanics system : Modeling, analysis and simulation

    Author : Arthur Vromans; Adrian Muntean; Martin Lind; Mohammad Asadzadeh; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; reaction-diffusion-mechanics model; parameter delimitation; parabolic-pseudoparabolic equations; weak solvability; Rothe method; periodic homogenization; Matematik; Mathematics;

    Abstract : In this thesis, parabolic-pseudoparabolic equations are derived coupling chemical reactions, diffusion, flow and mechanics in a heterogeneous medium using the framework of mixture theory. The weak solvability in 1-D of the obtained models is studied. READ MORE

  5. 3. The Black-Litterman Model : mathematical and behavioral finance approaches towards its use in practice

    Author : Charlotta Mankert; Birger Ljung; Ted Lindblom; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Black-Litterman Model; Portfolio Management; Portfolio Theory; Portfolio Models; Behavioral Finance; Business and economics; Ekonomi;

    Abstract : The financial portfolio model often referred to as the Black-Litterman model is analyzed using two approaches; a mathematical and a behavioral finance approach. After a detailed description of its framework, the Black-Litterman model is derived mathematically using a sampling theoretical approach. READ MORE

  6. 4. A laboratory vehicle mock-up research work on truck driver’s selected seat position and posture : A mathematical model approach with respect to anthropometry, body landmark locations and discomfort

    Author : Kianoush Fatollahzadeh; Jan Forslin; Roland Kadefoers; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; truck driving; anthropometry; body landmarks; discomfort; sitting posture; Other industrial engineering and economics; Övrig industriell teknik och ekonomi;

    Abstract : Professional truck drivers are highly exposed to fatigue and work related injuries. Truck drivers are common victims of musculoskeletal disorders, frequently suffering from pain symptoms particularly in the neck, shoulder and lower back. This situation is believed to be a contributor to the high absenteeism in this job category. READ MORE

  7. 5. Early Information Processing in the Vertebrate Olfactory System : A Computational Study

    Author : Malin Sandström; Anders Lansner; Dominique Martinez; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; olfaction; olfactory system; olfactory bulb; synchronisation; CaMKII; mathematical modelling; Computer science; Datavetenskap;

    Abstract : The olfactory system is believed to be the oldest sensory system. It developed to detect and analyse chemical information in the form of odours, and its organisation follows the same principles in almost all living animals - insects as well as mammals. READ MORE
