1. 1. Cold lap formation in Gas Metal Arc Welding of steel : An experimental study of micro-lack of fusion defects

   Författare :Peigang Li; Lars-Erik Svensson; Norbert Enzinger; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tandem GMAW; old laps; lack of fusion; Spatter; Overlap; Overflow; Manganese; Silicon; Oxides; Temperature; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Cold laps are defined as micro-lack of fusion defects at the weld toe more or less parallel to the surface of the parent plate. These defects are known to negatively influence the fatigue properties of weldments. Previous studies suggest that cold lap formation can not be avoided completely in Gas Metal Arc Welding (GMAW).

3. 2. Experimental Study on Cold Lap Formation in Tandem Gas Metal Arc Welding

   Författare :Peigang Li; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxides; imperfection; spatter; silicon; lack of fusion; overflow; temperature energy; overlap; cold lap; manganese; tandem GMAW;

   Sammanfattning : Tandem gas metal arc welding (GMAW) is a high productivity welding process which is appliedin many industries. However, a type of imperfection, known as cold lap, was revealed thatmostly accompanies the tandem GMAW process. LÄS MER

4. 3. Towards efficient overflow-free solvers for systems of triangular type

   Författare :Angelika Beatrix Schwarz; Lars Karlsson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datalogi;

   Sammanfattning : Triangular linear systems are fundamental in numerical linear algebra. A triangular linear system has a straight-forward and efficient solution strategy, namely forward substitution for lower triangular systems and backward substitution for upper triangular systems. LÄS MER

5. 4. An Exploration of Information Inadequacy: Instances that Cause the Lack of Needed Information

   Författare :Miranda Kajtazi; Darek Haftor; Anita Mirijamdotter; Marcelo Milrad; Sören Brier; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; information; information inadequacy; information lack; information overflow; hermeneutic approach; grounded theory approach; Informatics; computer and systems science; Informatik; data- och systemvetenskap; Information Systems; Informatik;

   Sammanfattning : Information is one of the most essential resources in our contemporary societies, as it guideshuman thinking, planning and subsequent actions, which in turn generates consequencesthat are desired or not. The Lehman Brothers bankruptcy in 2008, the tsunami in Indonesiain 2004, the Space Shuttle Challenger destruction in 1986 are just three instances ofdramatic situations, emerging continuously, where information plays a crucial role.

   Sammanfattning : This thesis explores the cultural history of microfilm and microphotography during the period 1900–1970, thus contributing to the broader field of research on the history of 20th century information management in the era before digital technology. The aim is to study how microfilm repeatedly, in various contexts and over time, was described and perceived as a new medium. LÄS MER
