  2. 1. Capacity-constrained production-inventory systems : using Laplace transforms and input-output analysis

    Author : Zhiping Wang; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Production-Inventory Systems; Computer science; Datavetenskap;

    Abstract : This work is concerned with multi-level, multi-stage capacity-constrained production-inventory problems. The aim is to provide a contribution to a theoretical background for Material Requirements Planning (MRP) using the Laplace Transform approach and Input-Output Analysis. READ MORE

  4. 2. Fast Radon Transforms and Reconstruction Techniques in Seismology

    Author : Viktor Nikitin; Matematik LTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fourier transform FFT ; Radon transforms; GPU;

    Abstract : The measurements conducted in tomography and seismology typically yield large multidimensional data sets. This in combination with the fact that the data may have an irregular structure makes it computationally prohibitive to use simple reconstruction methods directly. READ MORE

  5. 3. Connect : Modelling Learning to Facilitate Linking Models and the Real World trough Lab-Work in Electric Circuit Courses for Engineering Students

    Author : Anna-Karin Carstensen; Jonte Bernhard; Christian Kautz; Linköpings universitet; []
    Keywords : Engineering Education; Engineering Education Research; Key concepts; Labwork; Laplace Transforms; Learning; Learning of a Complex Concept; Learning to model; Modelling learning; Models; Practical Epistemologies; Threshold concepts; Variation Theory;

    Abstract : A recurring question in science and engineering education is why the students do not link knowledge from theoretical classes to the real world met in laboratory courses.Mathematical models and visualisations are widely used in engineering and engineering education. READ MORE

  6. 4. Capacity Constraints in Multi-Stage Production-Inventory Systems : Applying Material Requirments Planning Theory

    Author : Thi Thu Thuy Huynh; Robert Grubbström; Ludvik Bogataj; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Requirements Planning; Laplace transform; Net Present Value; multi-stage multi-level production-inventory planning; Industrial engineering and economy; Industriell teknik och ekonomi;

    Abstract : In this thesis, capacity-constrained aspects of multi-level, multi-stage productionplanning are investigated. The aim has been to extend Material Requirements Planning Theory (MRP Theory) to cover more general problems dealing with capacity constraints, in particular when non-zero lead times are present and the processes take place in continuous time.

  7. 5. Weak Convergence of First-Rare-Event Times for Semi-Markov Processes

    Author : Myroslav Drozdenko; Dmitrii Silvestrov; Raimondo Manca; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; weak convergence; first-rare-event times; semi-Markov processes; Mathematical statistics; Matematisk statistik; Matematik tillämpad matematik;

    Abstract : I denna avhandling studerar vi nödvändiga och tillräckliga villkor för svag konvergens av första-sällan-händelsetider för semi-Markovska processer.I introduktionen ger vi nödvändiga grundläggande definitioner och beskrivningar av modeller som betraktas i avhandlingen, samt ger några exempel på situationer i vilka metoder av första-sällan-händelsetider kan vara lämpliga att använda.
