1. Model-based coding : extraction, coding, and evaluation of face model parameters
Sammanfattning : This thesis deals with model-based coding of human faces for low bitrate communication. The basicidea of model-based coding is that the appearance and motion of a human face are analysed. By thisanalysis, compact parameters allowing realistic visualization of a synthetic face are extracted. LÄS MER
2. Logistics-based Competition : A Business Model Approach
Sammanfattning : Logistics is increasingly becoming recognised as a source of competitive advantage, both in practice and in academia. The possible strategic impact of logistics makes it important to gain deeper insight into the role of logistics in the strategy of the firm. LÄS MER
3. Model and Reality : Connecting BIM and the Built Environment
Sammanfattning : The adoption of building information modeling (BIM) in the architecture, engineering, and construction (AEC) industry is changing the way informa-tion regarding the built environment is created, stored, and exchanged. In short, documents are replaced with databases, processes are automated, and timelines become more circular with an emphasis on managing the life cycles of all manufactured objects. LÄS MER
4. An Integrated Approach towards Model-Based Mechatronic Design
Sammanfattning : Mechatronic design is an enigma. On the one hand, mechatronic products promise enhanced functionality, and better performance at reduced cost. On the other hand, optimizing mechatronic design concepts is a major challenge to overcome during the design process. LÄS MER
5. Model Order Reduction Based on Semidefinite Programming
Sammanfattning : The main topic of this PhD thesis is complexity reduction of linear time-invariant models. The complexity in such systems is measured by the number of differential equations forming the dynamical system. This number is called the order of the system. LÄS MER
