  1. 1. Understanding the Capabilities of Route Collectors to Observe Stealthy Hijacks : Does adding more monitors or reporting more paths help?

    Författare :Alexandros Milolidakis; Dejan Manojlo Kostic; Marco Chiesa; Alberto Dainotti; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Border gateway protocol; Stealthy hijacking; BGP hijacking; Route collector; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Routing hijacks have plagued the Internet for decades. These attacks corrupt the routing table entries that networks use to forward traffic, causing affected network devices to route private and possibly sensitive Internet traffic towards the hijacker. LÄS MER

  3. 2. Positionsanalys vid beslutsfattande och planering : Ekonomisk analys på tvärvetenskaplig grund

    Författare :Peter Söderbaum; Mälardalens högskola; []
    Nyckelord :position; positionsanalys; beslutsfattande; planering; tvärvetenskap; ekonomi; tröghet; osäkerhet; miljöproblem; industriell ekonomi och organisation; Industrial Economics and Organisations;

    Sammanfattning : Positionsanalys presenteras som ett alternativ till traditionell Cost-Benefit analys (CBA). En mer tvärvetenskaplig och mångdimensionell ekonomisyn föreslås där ett tänkande i positions- eller tillståndstermer spelar en nyckelroll. LÄS MER

  4. 3. Impact of Surface Structures onDeposition and Erosion in a Tokamak

    Författare :Yushan Zhou; Henric Bergsåker; Ivancica Bogdanovic Radovic; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Deposition; erosion; JET; micro ion beam analysis; Deposition; erosion; JET; mikrojonstråleanalys; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Fusion is a potentially unlimited and environmentally friendly energy source for human society in the future. However, along the way towards the application of fusion energy there are still unresolved complications. Among them, deposition and erosion are two critical issues. LÄS MER

  5. 4. Measurements of High-Precision Atomic Data with Applications to Astrophysics and Cosmology

    Författare :Maria Aldenius; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atomic data; Ca; Cr; Fe; Mn; Mg; metal-poor stars; fine-structure constant; Fourier transform spectroscopy; nebulae; oscillator strengths; spectroscopy; wavelengths; Ti; Zn; Astronomy; Astronomi; Atomic and molecular physics; Atom- och molekylärfysik; rymdvetenskap; space research; cosmic chemistry; kosmisk kemi; branching fractions;

    Sammanfattning : Investigations of astrophysical spectra require accurate atomic data, such as wavelengths and transition probabilities. This thesis provides high-precision atomic data for astrophysical and cosmological applications. The measurements have been carried out using Fourier transform spectrometry on light produced in a hollow cathode light source. LÄS MER

  7. 5. Mot bättre hälsa : Dödlighet och hälsoarbete i Linköping 1860-1894

    Författare :Hans Nilsson; Jan Sundin; Linköpings universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; historical demography; infant mortality; Linköping; morbidity; mortality; public health; social history; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The decline in mortality was the most important cause of the great increase in population in Sweden in the 19th century. Especially important was the part played by the decline in infant mortality and mortality among small children. LÄS MER
