36. Models for coupled active-passive population dynamics : Mathematical analysis and simulation
Sammanfattning : In this dissertation, we study models for coupled active--passive pedestrian dynamics from mathematical analysis and simulation perspectives. The general aim is to contribute to a better understanding of complex pedestrian flows. LÄS MER
37. Numerical Approximation of Reaction and Diffusion Systems in Complex Cell Geometry
Sammanfattning : The mathematical modelling of the reaction and diffusion mechanism of lipophilic toxic compounds in the mammalian cell is a challenging task because of its considerable complexity and variation in the architecture of the cell. The heterogeneity of the cell regarding the enzyme distribution participating in the bio-transformation, makes the modelling even more difficult. LÄS MER
38. Modelling and Reliability Assessment of Microsystem Interconnections
Sammanfattning : With the continuous increase of packaging density, the electronic component size and, in particular, the thickness of the involved interconnections decrease significantly. In addition, the microsystem interconnects usually include even finer internal structures. LÄS MER
39. Investigation of Surface Formation in As-Cast and Homogenized 6xxx Aluminium Billets
Sammanfattning : The direct chill (DC) casting technique to produce billets for extrusion and ingots for rollingwas developed in the 1930s. The principle, which is still valid, is a two-stage cooling with a primary cooling at a mould surface followed by water spraying directly on the surface. LÄS MER
40. A Study on Structural Cores for Lightweight Steel Sandwiches
Sammanfattning : Lightweight materials and structures are essential building blocks for a future with sustainable transportation and automotive industries. Incorporating lightweight materials and structures in today's vehicles, reduces weight and energy consumption while maintaining, or even improving, necessary mechanical properties and behaviors.
