2. 1. The use of a satellite-derived cloud climatology for studying cloud-aerosol processes and the performance of regional cloud climate simulations

   Author : Karl-Göran Karlsson; Erland Källen; Jon-Egil Kristjansson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Clouds and climate; satellite cloud climatology; validation of clouds; clouds and aerosols; Meteorology; Meteorologi;

   Abstract : The entry of satellite-derived decadal cloud datasets with homogeneous coverage in time and space enables studies not possible before. This thesis presents two such applications. The first study deals with cloud-aerosol processes and the second with an evaluation of cloud simulations from a regional climate model. READ MORE

4. 2. Event-triggered control of multi-agent systems: pinning control, cloud coordination, and sensor coverage

   Author : Antonio Adaldo; Karl H. Johansson; Kristin Y. Pettersen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Abstract : A multi-agent system is composed of interconnected subsystems, or agents. In control of multi-agent systems, the aim is to obtain a coordinated behavior of the overall system through local interactions among the agents. Communication among the agents often occurs over a wireless medium with finite capacity. READ MORE

5. 3. On Service Optimization in Community Network Micro-Clouds

   Author : Nuno Apolonia; Leandro Navarro; Sarunas Girdzijauskas; Felix Freitag; Vladimir Vlassov; Dino Lopez; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; micro-clouds; Community Networks; cloud services; social networks; overlay networks; distributed systems; Datalogi; Computer Science;

   Abstract : Internet coverage in the world is still weak and local communities are required to come together and build their own network infrastructures. People collaborate for the common goal of accessing the Internet and cloud services by building Community networks (CNs).The use of Internet cloud services has grown over the last decade. READ MORE

6. 4. Satellite measurements of upper tropospheric water

   Author : Mattias Ekström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; cloud ice; upper troposphere; microwave; retrieval; the Odin satellite; humidity; limb-sounding;

   Abstract : Water vapour and clouds in the upper troposphere have strong influence on the Earth's climate system. The present uncertainties regarding the distribution and feedback mechanisms of water to a changing climate are today among the greatest limitations for accurate climate predictions. READ MORE

7. 5. Retrieving cloud ice masses from geostationary images with neural networks

   Author : Adrià Amell Tosas; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; machine learning; geostationary satellites; ice clouds;

   Abstract : Clouds are essential to the Earth's energy budget and atmospheric circulation. Despite this, many cloud parameters are poorly known, including the mass of frozen hydrometeors. On the one hand, there will be specialized satellite missions targeting such hydrometeors. On the other hand, existing satellite data can be leveraged. READ MORE
