21. The capital cost of holding inventory - A real options approach
Sammanfattning : This thesis is based on three scientific papers dealing with costs and financial risks associated with keeping stock. Reasonable cost parameters are important to implement an effective inventory control system, which in turn is one of the key activities in logistics management. All three papers consider a single-level inventory system. LÄS MER
22. A CFT perspective on holographic correlators
Sammanfattning : Conformal symmetry is ubiquitous in physics. It emerges in a variety of situations from critical phenomena, through condensed matter systems and jets at the LHC to string theory. Conformal field theories (CFTs) describe the universal behavior underlying these very different setups. LÄS MER
23. On Methods for Discrete Topology Optimization of Continuum Structures
Sammanfattning : This thesis consists of an introduction and seven appended papers. The purpose of the introduction is to give an overview of the field of topology optimization of discretized load carrying continuum structures. LÄS MER
24. The mechanics in two nanosized systems : Size effect and threshold field
Sammanfattning : This thesis investigates the mechanics in two nanosized system. Paper I investigates a size effect in a cantilever nanowire affecting its resonance frequency. Paper II reveals a threshold field for the formation of a mound by the diffusion of surface atoms on a substrate under a STM-tip. LÄS MER
25. CFD and data-driven modeling for safe spillway discharge
Sammanfattning : A spillway is a crucial dam structure that regulates water levels and prevents the dam from overtopping. The majority of the dams in the world were constructed before the 1980s. Compared to the current design flood standards, many spillways are undersized, e.g. LÄS MER
