1. 1. Composites for commercial ships

   Författare :Måns Håkansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design; ship; composites; commercial vessels; optimization; weight reduction; cost-efficient design;

   Sammanfattning : Composite materials have been used in marine applications for more than 50 years, and benefits such as low weight, low maintenance requirements and freedom of design are well known. A wider use of composites in larger, commercial vessels has been limited by initial costs and fire regulations, but both of these obstacles are diminishing. LÄS MER

3. 2. Direct Calculation of Wave-Induced Loads and Fatigue Damage of Container Vessels

   Författare :Zhiyuan Li; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; fatigue; stress concentration factor; direct calculation; Container ship; fatigue routing; wave-induced torsion.; extreme loading; nonlinear wave loads;

   Sammanfattning : Container ships and their rules for fatigue design are in several ways differentcompared with other types of commercial ships such as tankers and bulk carriers. Forexample, most modern container ships have a pronounced bow flare and an overhangstern. LÄS MER

4. 3. Glass, alcohol and power in Roman Iron Age Scotland - a study of the Roman vessel glass from non-Roman/native sites in north Northumberland and Scotland

   Författare :Dominic Ingemark; Antikens kultur och samhällsliv; []
   Nyckelord :HUMANIORA; HUMANITIES; Celtic and Germanic drinking customs; Roman; Symbols of power; Material culture; Presitige goods systems; Roman–native exchange; Free Germany; Roman glass; Iron Age Northumberland Scotland; Wine; mead; beer; Archaeology; Arkeologi;

   Sammanfattning : This thesis is based on a study of Roman glass vessels found on non-Roman/native sites - chiefly of Roman Iron Age date (AD 0-400) - beyond Hadrian’s Wall in northern Britain. Roman glass vessels have been discovered on 60 sites in total, the majority of which are settlements of various types, and only a minor part are graves. LÄS MER

5. 4. Immersion and recreational boating-related injuries in Alaska

   Författare :Diana Stark Hudson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Alaska; injuries; drowning; cold water; immersion; submersion; hypothermia; survival;

   Sammanfattning : Background: Cold water is an ever-present hazard in Alaska, and when water-related injuries occur, they often take place in remote environments, where the nearest trained emergency response teams are several hours away. Alaska’s crude drowning death rate in 2002 was 4. LÄS MER

7. 5. Risk-based ship security analysis : a decision-support approach

   Författare :Hans Liwång; Jonas W. Ringsberg; Martin Norsell; Rolf Skjong; Försvarshögskolan; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; naval ship; piracy; risk-based; risk control options; ship security analysis; survivability; uncertainty analysis; militära fartyg; sjöröveri; riskanalys; sjöfartsskydd; överlevnadsförmåga; Försvarssystem; Military Technology;

   Sammanfattning : The protection of shipping does not come without hazards and threats for military forces, individual civilian ship operators and crews. With particular focus on security threats, this thesis is about how to prepare for such operations without introducing unnecessary risks, i.e., supporting conscious risk-taking related to ship security.
