1. Phytoplankton and Physical Disturbance : Seasonal dynamics in temperate Lake Erken, Sweden
Sammanfattning : Phytoplankton mirrors changes in the environment and plays an important role in biogeochemical processes. Phytoplankton dynamics is the outcome of both autogenic succession and external disturbances. LÄS MER
2. Railway traffic disturbance management
Sammanfattning : With the increasing traffic volumes in many railway networks and reports on capacity deficiencies that result in insufficient punctuality and reliability, the need for efficient disturbance management solutions becomes evident. This thesis focuses on solutions that aim to minimise the consequences of disturbances for the various stakeholders and specifically on methods for re-scheduling the traffic. LÄS MER
3. Digital Lean Disturbance Management
Sammanfattning : As a realization of visualization and simplification principles in lean, lean methods typically employ physical tools. However, being physical is both strength and weakness of lean tools. Being physical is a strength, because physical lean tools are easy to implement, easy to learn and easy to use. LÄS MER
4. Ecological disturbances: the good, the bad and the ugly
Sammanfattning : Abstract. This thesis focuses on the definitions, characterizations and quantifications of ecological disturbances, as well as hypotheses on their impacts on biological communities. LÄS MER
5. Resistance and recolonization of bryophyte assemblages following disturbances : - detecting patterns and exploring mechanisms
Sammanfattning : Disturbances are ubiquitous features of most northern forest ecosystems. The subsequent response of plant assemblages on both short (resistance or not) and long term (recolonization or not) will depend on a number of factors operating at several spatial scales. LÄS MER
