3. 2. Solid Waste Landfills in an Arid Environment : Site Selection and Design

   Författare :Ali Chabuk; Jan Laue; Nadhir Al-Ansari; Sven Knutsson; Hussain M. Hussain; Roland Pusch; Rafid Alkhaddar; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Landfill; Arid Environment; Site selection; Design; Babylon; Iraq; Soil Mechanics; Geoteknik;

   Sammanfattning : Selecting landfill sites is considered a complicated task because its whole process is based upon several factors and restrictions. This study shows the present status of solid waste management, sources, collection personnel, machinery and equipment that are involved in the waste collection process, financing and financial management for the major cities of the Babylon Governorate in Iraq (Al-Hillah, Al-Qasim, Al-Mahawil, Al-Hashimiyah and Al-Musayiab).

4. 3. Reduction in ground vibrations by the use of wave obstacles

   Författare :Peter Persson; Byggnadsmekanik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The increasing size of the population results in that unbuilt spaces needing to be used for the construction of new facilities. Large construction sites can generate disturbing vibrations to nearby buildings, both while construction is underway and afterwards through the operation of subways, for example. LÄS MER

5. 4. Vibrations in a Built Environment : Prediction and Reduction

   Författare :Peter Persson; Byggnadsmekanik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration reduction; finite element method; coupled problems; vibration measurements; wave propagation; ground vibration; soil dynamics; wave barrier; shaped landscape; soil stabilisation; liquid-filled pipes; model order reduction;

   Sammanfattning : Vibrations in a built environment can exceed the requirements for sensitive equipment in a building or can cause annoyance to residents. Hence, there is often a need for reducing such vibrations. The vibrations can originate from ambient sources such as motorway traffic, or from internal sources such as people walking inside the building. LÄS MER

7. 5. On the dynamics of an hydropower generator subjected to unbalanced magnetic pull : characterisation and analysis

   Författare :Yogeshwarsing Calleecharan; Rolf Gustavsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

   Sammanfattning : Eccentricity leading to unbalanced magnetic pull (UMP) in rotating electrical machines is a significant concern in industry. The UMP arises due to magnetic flux crossing the air-gap between the rotor and stator, and can be more intense than the useful peripheral force that the machine develops. LÄS MER
