1. 1. Cellular-Internet-of-Things Enablers: : A Techno-Economic Study of Wide Area Networks Connectivity and Platform Solutions

   Författare :Mohammad Istiak Hossain; Jan Markendahl; Jens Zander; Heikki Hämmäinen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IoT; LPWAN; 5G; PRACH Contention Resolution; Multiplicity detection; Resource Allocation; Cost Structure.; Telecommunication; Telekommunikation; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Internet of Things (IoT) services are gradually attaining the expected service growth rate estimated by market actors. New connectivity paradigms, like the low-power wide-area network (LPWAN), have emerged to address the immediate challenges of IoT connectivity service. LÄS MER

3. 2. Characterising Young Stellar Binaries

   Författare :Per Calissendorff; Markus Janson; Eric Stempels; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Binaries; stellar ages; multiplicity; Astronomy; astronomi;

   Sammanfattning : Stars are dispersed all over the sky within our Galaxy, appearing in large varieties of ages and sizes. How- ever, estimating said traits proves not to always be trivial, but certain circumstances allow us to probe the characteristics of stellar binaries. LÄS MER

4. 3. Neutron Multiplicity Counting with the Analysis of Continuous Detector Signals

   Författare :Lajos Nagy; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kolmogorov equation; fissile material assay; nuclear safeguards; fission chamber; neutron multiplicity counting; master equation;

   Sammanfattning : Neutron multiplicity counting is a non-destructive assay method for determining the mass of fissile materials (primarily plutonium) using the measured values of the singles, doubles and triples detection rates. Traditionally, the detection rates are obtained from the counting statistics of neutron detectors. LÄS MER

5. 4. Generalised Campbell formulae for compound Poisson processes with applications in nuclear safeguards

   Författare :Lajos Nagy; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; passive non-destructive assay; fissile material assay; multiplicity counting;

   Sammanfattning : Multiplicity counting is a widely used non-destructive assay method for estimating unknown parameters (primarily the mass) of samples of spontaneously fissioning materials (e.g. plutonium). Traditionally, measurements are performed with thermal neutron detectors operating in pulse counting mode. LÄS MER

7. 5. Stellar Surface Structures and the Astrometric Serach for Exoplnaets

   Författare :Urban Eriksson; Lindegren Lennart; Kristianstad University; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astrometry; astronomy;

   Sammanfattning : Measuring stellar parallax, position and proper motion is the task of astrometry. With the development of new and much more accurate equipment, different noise sources are likely to affect the very precise measurements made with future instruments. LÄS MER
