2. 1. Vibroacoustic performance of wooden buildings : Prediction and Perception

   Author : Juan Negreira; Teknisk akustik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prediction tools; Low frequency vibrations; Vibroacoustics; Wooden buildings; Impact sound insulation; Finite element method; Vibration measurements; Flanking transmission; Elastomers; Design indicators; Vibration acceptability; Vibration annoyance; MEMS accelerometers;

   Abstract : When the Swedish building regulations in 1994 allowed wooden multi-storey buildings to be built, this type of lightweight construction became popular due to its low cost and ease of construction, as well as wood being a plentiful resource in Sweden. However, complaints amid inhabitants are often reported due to nuisances caused by disturbing vibrations and noise propagating in the building. READ MORE

4. 2. Vibrations in Lightweight Buildings - Perception and Prediction

   Author : Juan Negreira; Teknisk akustik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Psycho-vibratory evaluation; Vibrations; Timber floors; Lightweight; Measurements; Serviceability criteria; Vibration annoyance; Vibration acceptability; Elastomer; Finite element method; Prediction Tools.;

   Abstract : When the Swedish construction code (in 1994) allowed wooden multi-storey buildings to be built, this type of lightweight construction became popular due to its low cost and ease of construction, and also because wood is a plentiful resource in Sweden. Drawbacks in such buildings are disturbing vibrations and noise propagating in the construction, especially through junctions. READ MORE

5. 3. Vibration transfer process during vibratory sheet pile driving : from source to soil

   Author : Fanny Deckner; Staffan Hintze; Kenneth Viking; Steinar Nordal; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ground vibrations; sheet piles; vibratory driving; vibration transfer process; instrumentation system; field tests; numerical modelling; vibration prediction; markvibrationer; spont; vibrodrivning; vibrationsöverföringsprocessen; instrumenteringssystem; fältförsök; numerisk modellering; vibrationsprognosticering; Civil and Architectural Engineering; Byggvetenskap;

   Abstract : Vibratory driven sheet piles are a cost-effective retaining wall structure, and in coming decades the continued use of this method will be crucial for minimising costs within the construction sector. However, vibratory driven sheet piles are a source of ground vibrations, which may harm structures or induce disturbance. READ MORE

6. 4. Cost Effective Maintenance for Competitve Advantages

   Author : Imad Alsyouf; Basim Al-Najjar; Uday Kumar; Växjö universitet; []
   Keywords : Maintenance approaches; Maintenance Costs; Savings and Profit; Operations; Quality; Effectiveness; Efficiency; Competitiveness; Productivity; Value Advantages; Profitability; Performance; Balanced Scorecard BSC; Maintenance Selection Method; Fuzzy MCDM; TTT-plot; Cost Effective Maintenance; Mechanistic Model; Vibration Level Prediction; Condition-Based Maintenance; survey; case study; TECHNOLOGY; TEKNIKVETENSKAP; Maskinteknik; Mechanical Engineering;

   Abstract : This thesis describes the role of cost effective maintenance in achieving competitive advantages. It explores by means of a survey which maintenance practices are used, and how maintenance policies are selected in Swedish industries. READ MORE

7. 5. Damage Tolerance of Impacted Composite Sandwich Structures

   Author : Moeen ud din Saeed Rajput; Malin Åkermo; Stefan Hallström; Magnus Burman; Christian Berggreen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composite sandwich; cellular; polymer; material characterization; modulus; non-crimp fabric; low velocity impact; vibration; uncertainty analysis; drop-weight impact; fractography; barely visible impact damage; X-ray microtomography; compression-after-impact; bending-after-impact; high speed image processing; damage resistance; damage tolerance; Aerospace Engineering; Flyg- och rymdteknik;

   Abstract : This thesis deals with damage tolerance of impacted sandwich structures for load bearing applications. Composite sandwich structures find wide application as lightweight solutions in aerospace components, since weight reduction and less fuel emissions are primary concerns for aircraft manufactures.
