   Nyckelord :Remote sensing; reconnaissance; sensor; information acquisition; satellite imagery; image processing; image analysis; change detection; pixel difference; neuron network; cortex model; PCNN; ICM; entanglement; Earth observation; nuclear explosion; SPO;

   Sammanfattning : This thesis, Earth satellites and detection of air andground based activities by Ulf Ekblad of the Physics departmentat the Royal Institute of Technology (KTH), addresses theproblem of detecting military activities in imagery. Examplesof various techniques are presented. LÄS MER

3. 2. Cell-penetrating peptides, novel synthetic nucleic acids, and regulation of gene function : Reconnaissance for designing functional conjugates

   Författare :Peter Guterstam; Ülo Langel; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell-penetrating peptide; nucleic acids; alternative splicing; mismatch discrimination; Neurochemistry; Neurokemi;

   Sammanfattning : Our genome operates by sending instructions, conveyed by mRNA, for the manufacture of proteins from chromosomal DNA in the nucleus of the cell to the protein synthesizing machinery in the cytoplasm. Alternative splicing is a natural process in which a single gene can encode multiple related proteins. LÄS MER

4. 3. Antenna array mapping for DOA estimation in radio signal reconnaissance

   Författare :Per Hyberg; Björn Ottersten; Alex Gershman; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Array mapping; array interpolation; Signalbehandling; Signal processing; Signalbehandling;

   Sammanfattning : To counter radio signal reconnaissance, an efficient way of covert communication is to use subsecond duration burst transmissions in the congested HF band. Against this background, the present thesis treats fast direction finding (DF) using antenna arrays with known response only in a few calibration directions. LÄS MER

7. 5. La perception du français oral par des apprenants suédois

   Författare :Monika Stridfeldt; Barbro Nilsson; Ingmarie Mellenius; Paul Touati; Chantal Lyche; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; French language; perception de la parole; reconnaissance des mots; français oral; acquisition de L2; apprenants de français; processus phonologiques; effacement du schwa; liaison; enchaînement; assimilation de sonorité; Franska; French language; Franska språket; Linguistics; lingvistik;

   Sammanfattning : Swedish learners of French often experience large difficulties in understanding spoken French. Words that the learners know very well when written or when pronounced separately are often hard to recognize in the speech flow. The aim of this study is to examine Swedish learners’ perception of French speech in order to identify the problems. LÄS MER
