  1. 1. Spectroscopic Studies of Isomers Produced in Relativistic Projectile Fragmentation and In-Flight Fission

    Author : Milena Mineva; Lunds universitet.; Lund University.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Projectile fragmentation; nuclear structure; isomeric states; lifetimes; production rates; Kärnfysik; isomeric ratios; Nuclear physics; Fysicumarkivet A:000; in-flight fission;

    Abstract : This thesis is based on a number of experiments performed at the FRagment Separator (FRS) at the Gesellschaft für Schwerionenforschung mbH (GSI) in Darmstadt, Germany, in which heavy-ion reactions at relativistic energies have been used to produce nuclei far from stability. In April 1999 projectile fragmentation of 208Pb at 1 GeV/nucleon was used to study so called K-isomers in the neutron-rich isotopes of Lu (Z=71) to Hg (Z=80). READ MORE

  2. 2. Transition delay in boundary-layer flows via reactive control

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Nicolò Fabbiane; KTH.; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow control; drag reduction; net energy saving; adaptive control; model-based control; optimal control; flat-plate boundary layer; laminar-to- turbulent transition; plasma actuator; direct numerical simulation; in-flight experiments; strömningsstyrning; friktionsreduktion; netto energibesparing; adaptiv styrning; modellbaserad styrning; optimal kontroll; gränsskikt öve en plan platta; laminärt till turbulent omslag; plasma aktuator; DNS; flyg prov; Teknisk mekanik; Engineering Mechanics;

    Abstract : Transition delay in boundary-layer flows is achieved via reactive control of flow instabilities, i.e. Tollmien-Schlichting (TS) waves. Adaptive and model-based control techniques are investigated by means of direct numerical simulations (DNS) and experiments. READ MORE

  3. 3. Tilted Foils Nuclear Spin Polarization and Measurement with Coulomb Excitation

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Hans Törnqvist; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tilted; Foils; Polarization; Excitation; Coulomb; Nuclear; Spin;

    Abstract : Developing new experimental tools is essential to expand the possibilites of probing the structure of atomic nuclei. The better the currently known properties of nuclei can be manipulated, the more information can be extracted from data collected in nuclear reaction experiments. READ MORE

  4. 4. Assessment of Aircraft Radar Cross-Section for Detection Analysis

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Björn Persson; KTH.; Försvarshögskolan.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerospace Engineering; Flyg- och rymdteknik; Militärteknik; Militärteknik;

    Abstract : Att kunna gömma sig för att sedan överaska sin motståndare är en taktik som har använts inom krigsföring genom historien, detta var också en möjlighet flygplan erbjöd när de började användas i militära samanhang. Utveckling av teknik för militära ändamål är emellertid en ständigt pågående kamp mellan framsteg inom det befintliga teknikfältet och utveckling för att kunna motverka sådan teknik. READ MORE

  5. 5. Olfactory mechanisms of host selection in phytophagous insects

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Muhammad Binyameen; Sveriges lantbruksuniversitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The most challenging tasks for phytophagous insects are the location and selection of mates, food sources, and oviposition sites, all crucial for survival and reproduction. To perform these tasks insects rely largely on their sense of smell (olfaction). READ MORE
