  1. 1. Effects of planetary radius contraction on scattering

    University essay from Lunds universitet/Astronomi

    Author : Viktor Hrannar Jónsson; [2020]
    Keywords : Physics and Astronomy;

    Abstract : The observed high orbital eccentricities of many giant exoplanets is thought to be the result of gravitational scattering between planets. Outcomes of planet-planet scattering can result in some planets being lost by ejections into interstellar space, or collisions between planets or with the star. READ MORE

  2. 2. Design of Eccentric Double Amplitude Vibration Drum Roller Shaft with Improved Mass Moment of Inertia : Product Development of Compaction Equipment

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Marika Blad; Alexander Tynnerstål Balog; [2020]
    Keywords : Eccentricity; mass moment of inertia; double amplitude feature; vibration; Excentricitet; masströghetsmoment; dubbelamplitud; vibration;

    Abstract : Road construction is important to make transports safe and sustainable. To compact asphalt an amount of energy needs to be conducted into the material either by static pressure or dynamic vibrations. An asphalt-roller compact the material and increases its load-bearing capacity. READ MORE

  3. 3. Mechanical Face Seals: Test Rig Development and Analysis of the Frictional Behaviour

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Àlex de la Cruz Gargallo; Víctor Pérez Palomino; [2019]
    Keywords : Mechanical Face Seal; Friction; Test Rig; Lubrication Regimes; Mekanisk glidringstätning; Friktion; Provningsbänk; Smörjningsregimer;

    Abstract : Mechanical face seals, MFS, are important machine components in the heavyduty-vehicle industry which generate a high frictional power loss. In order to lower these losses an investigation has to be performed on the frictional behavior of the MFS. READ MORE

  4. 4. The Relationship Between a Variable Orbital Eccentricity and Climate on an Earth-Like Planet

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Ellinor Wanzambi; [2019]
    Keywords : climate; climate models; exoplanets; Earth-like planets; klimat; klimatmodeller; exoplaneter; jordliknande planeter;

    Abstract : By using climate models based on the Earth’s climate, you can get information about how the climate on exoplanets can look like. ROCKE-3D is a general circulation model based on ModelE2, which is used for simulations of modern and prehistoric Earth’s climate. READ MORE

  5. 5. 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
