   Keywords : HUMANIORA; HUMANITIES; Classical archaeology and ancient history; Etruscan; San Giovenale; bridge; chthonic; Vesuna; Lurs Larunita; gens; Urcena; Larth; Fasthi Alsi; sacellum; Orientalizing; Protovillanovan; Archaic; Hellenistic; pottery; Greek imports; inscriptions; ritual; liminal; rites of passage; sacrifices; banqueting; transit road; multiple functions; continuity; change; Antikens kultur och samhällsliv; Classical archaeology and ancient history; Antikens kultur och samhälle; arkeologi; Archaeology;

   Abstract : This thesis discusses the archaeological remains in the Etruscan bridge complex, found during the excavations at San Giovenale in 1959–1963, and 1999. The aim has been to reach a holistic perspective of the bridge complex with the bridge seen as a link between topography, economy, social relationships, politics, symbols and ritual, reflecting its importance for the whole community at San Giovenale and its surroundings.

4. 2. Bracing of steel bridges during construction; theory, full-scale tests and simulations

   Author : Hassan Mehri; Avdelningen för Konstruktionsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bracing; steel-concrete composite; steel; bridge; test; construction; laboratory; experiment; experimental; theory;

   Abstract : A number of steel bridges have suffered lateral-torsional failure during their construction due to their lacking adequate lateral and/or rotational stiffness. In most cases, slight bracing can be of great benefit to the main girders involved through their controlling out-of-plane deformations and enabling the resistance that is needed to be achieved.

5. 3. Machine tool vibrations and violin sound fields studied using laser vibrometry

   Author : Kourosh Tatar; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

   Abstract : The knowledge of the dynamic behaviour of a milling process is very important for finding an optimum process window. In today's manufacturing industry the machining parameters are often predicted using experimental data from non-rotating spindles. READ MORE

6. 4. Structural Identification of Civil Engineering Structures

   Author : Tarek Edrees; Andreas Andersson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Abstract : The assumptions encountered during the analysis and design of civil engineering structures lead to a difference in the structural behavior between calculations based models and real structures. Moreover, the recent approach in civil engineering nowadays is to rely on the performance-based design approaches, which give more importance for durability, serviceability limit states, and maintenance.

7. 5. Spindle vibration and sound field measurement using optical vibrometry

   Author : Kourosh Tatar; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Abstract : Mechanical systems often produce a considerable amount of vibration and noise. To be able to obtain a complete picture of the dynamic behaviour of these systems, vibration and sound measurements are of significant importance. Optical metrology is well-suited for non-intrusive measurements on complex objects. READ MORE
