  1. 1. Mean Motion Resonances and Planetary Scattering

    University essay from Lunds universitet/Astronomi; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Erik Dahlöf; [2018]
    Keywords : mean motion resonance; orbit resonance; planetary dynamics; planet-planet scattering; planetary scattering; eccentricity; inclination; planet systems; disturbing force; orbit dynamics; orbital elements; planets; exoplanets; scattering phase; relaxation; dynamical instabilities; N-body; protoplanetary disk; planet migration; eccentricity damping; inclination damping; planet-disk interactions; Physics and Astronomy;

    Abstract : The observed distribution of giant exoplanet eccentricities and inclinations are significantly larger than what is measured for their Solar system analogues, Jupiter and Saturn. Since the first observations of exoplanets, planet-planet scattering has been proposed as a possible mechanism for exciting the eccentricities and inclinations of giant exoplanets. READ MORE

  3. 3. Modal Testing and Structural Identification

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Author : Tobias Kristensson; [2014]
    Keywords : Modal testing; Modal analysis; Structural identification; Vibration; Signal; EMA; OMA; Technology and Engineering;

    Abstract : Bridges have been built around the world for at least 3000 years and have made it possible for man to travel over obstacles like valleys and rivers, which has contributed to the rapidly growing infrastructure we have today. Efforts made to save materials and reduce production costs have led to lighter and slender structures, which in turn can cause dynamic problems where the bridge is sensitive to vibrations. READ MORE

  4. 4. Sustainable bio-fuels production : an institutional analysis of bio-fuels industry in Tanzania : the case of Rufiji River basin

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Rajabu Hamisi Mohamed; [2009]
    Keywords : sustainable development; institution; bio-fuels; land; water resource; energy;

    Abstract : Bio-fuels production are important alternatives to fossil fuel, but bio-fuels are also associated with risks of displacing rural communities during the process of acquiring land, disturbing hydrological cycle- water scarcity, biodiversity loss, limit animal migration, displacement of native plant species, and ,hence, potential land use conflicts. Tanzania is well known as a blessed country endowed with numerous and diverse land and water resources in the form of rivers, lakes, wetlands and aquifers. READ MORE

  5. 5. Review of Asylum Policies and Procedures in The Bahamas: Are Current Policies and Procedures Consistent with International Instruments for the Protection of Refugees?

    University essay from Lunds universitet/Juridiska institutionen

    Author : Deneisha Moss; [2006]
    Keywords : International Human Rights Law; Law and Political Science;

    Abstract : Volatile conflicts, poverty and suppression of basic human rights stemming from one's political or religious affiliations, gender and race, are some of the various reasons why thousands flee home in the hopes of finding some kind of security. As the world observes the appalling deterioration of conflicts in Western Sudan, Iraq and Haiti, we simultaneously observe neighbouring or developed countries securing their borders in an effort to prevent an influx of refugees on to their territories.
