2. 1. Theoretical studies on photophysics and photochemistry of DNA

   Author : Yuejie Ai; Yi Luo; Lluís Blancafort; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; Kvantkemi; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

   Abstract : Theoretical studies on biological systems like nucleic acid and protein have been widely developed in the past 50 years and will continue to be a topic of interest in forefronts of natural science. In addition to experimental science, computational modeling can give useful information and help us to understand biochemical issues at molecular, atomic and even electronic levels. READ MORE

4. 2. Impulse Radio UWB for the Internet-of-Things : A Study on UHF/UWB Hybrid Solution

   Author : Zhuo Zou; Hannu Tenhunen; Tor Sverre Lande; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra-Wideband; impulse radio; IR-UWB; RFID; asymmetric links; UHF UWB hybrid; wireless sensing; energy detection; low power; radio receiver; positioning; Internet-of-Things;

   Abstract : This dissertation investigates Ultra-Wideband (UWB) techniques for the next generation Radio Frequency Identification (RFID) towards the Internet-of-Things (IoT). In particular, an ultra-high frequency (UHF) wireless-powered UWB radio (UHF/UWB hybrid) with asymmetric links is explored from system architecture to circuit implementation. READ MORE

5. 3. Pair production of Higgs bosons in the final state with bottom quarks and τ leptons in the ATLAS experiment : Search results using LHC Run 2 data and prospect studies at the HL-LHC

   Author : Petar Bokan; Arnaud Ferrari; Stan Lai; Richard Brenner; Markus Klute; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Higgs boson pair production; ATLAS; LHC; HL-LHC; particle physics; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Abstract : After the discovery of the Higgs boson, the ultimate test of the electroweak symmetry breaking and the Standard Model (SM) of particle physics is to establish evidence of Higgs boson self-coupling, which can be achieved by searching for pair production of Higgs bosons. In addition, many theories beyond the SM predict heavy resonances that could decay into pairs of Higgs bosons. READ MORE

6. 4. Alternative electronic packaging concepts for high frequency electronics

   Author : Wolfgang Peter Siebert; Sture Petersson; Shaofang Gong; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Connector; cooling; electronic; elastomer interconnect; EMC; shielded enclosure; high frequency; PCB; PWB; reverberation chamber; seams; soldering; twisted pair cable; Elektroteknik; Electrical engineering; Elektroteknik;

   Abstract : The aim of the research work presented here, is to contribute to the adaptation of electronic packaging towards the needs of high frequency applications. As the field of electronic packaging stretches over several very different professional areas, it takes an interdisciplinary approach to optimize the technology of electronic packaging. READ MORE

7. 5. Resonant multi-photon ionisation studies of high-energy states in small molecules

   Author : Marica Sjödin; Lars-Erik Berg; Arne Rosén; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Abstract : This thesis describes separate studies of high-energy Rydberg and ion-pair states in small molecules using resonant multi-photon ionisation spectroscopy. * OODR/REMPI study of ungerade Rydberg states in O2 The energy region between 75000 and 99900 cm-1 of O2 has been studied using optical-optical double resonance (OODR) with resonance enhanced multi-photon ionisation (REMPI).
