1. On Energy Management Strategies for Hybrid Electric Vehicles
Sammanfattning : Hybrid electric vehicles are characterized by the existence of an electric energy buffer in the powertrain. Compared to a conventional vehicle the existence of the buffer means an extra degree of freedom in the powertrain. LÄS MER
2. Radical Innovation: Management and policy for electric and hybrid electric vehicle development
Sammanfattning : Technological change can be divided into two categories: in line with the mainstream trajectory or paradigm (continuous, incremental), or breaking with it (discontinuous, radical). This thesis aims to increase understanding of the latter type: paradigmatic shifts in technology. LÄS MER
3. Managing discontinuous changes in complex products : Cases involving the development and market introduction of heavy hybrid-electric buses
Sammanfattning : This is a study about managing the development of discontinuous changes in complex products characterised by integration of a significant amount of new technologies and firms’ existing technologies and market introduction of such products. In particular, this study analyses how firms’ technology selections influence the conditions for the firms to manage such development and market introduction. LÄS MER
4. Detached Eddy Simulation for Aerospace Applications
Sammanfattning : With the continuous growth in air traffic that we see nowadays, comes an increase in the requirements needed to be satisfied in order to certify an aircraft for operation. These stricter regulations affect aspects such as CO2 emissions, sound pollution and so on, pushing manufacturers to aim for lighter, more efficient, more robust designs. LÄS MER
5. Design of Assured and Efficient Safety-critical Systems
Sammanfattning : Safety-critical systems need to be analyzed rigorously to remove software/specifications errors, that is, their requirements specifications should be unambiguous, comprehensible and consistent, and the software design should conform to the specifications, hence avoiding undesirable system failures. Currently, there is a lack of effective and scalable methods to specify and analyze requirements, and formally analyze the behavioral models of embedded systems. LÄS MER
