1. 1. Studies in Glacier Mass Balance : Measurement and its errors

   Författare :Andrew Mercer; Peter Jansson; Gunhild Rosqvist; Ian Brown; Jonathan Carrivick; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Glaciology; Mass Balance; Measurement Errors; Physical Geography; naturgeografi;

   Sammanfattning : The study of the surface mass balance of valley glaciers has a long history but one that is dogged by uncertainty and errors, and uncertainty about those errors. These problems are acknowledged by the glaciological community and have been examined and formalised in several publications. LÄS MER

3. 2. Reluctantly Virtual : Modelling Copyright Industry Dynamics

   Författare :Patrik Wikström; Robert Burnett; Will Straw; Karlstads universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Music industry dynamics; Internet; Media; Production of culture; Qualitative system dynamics modelling; Organisational adaptation; Copyright; Media and communication studies; Medie- och kommunikationsvetenskap; Media and Communication Studies; Medie- och kommunikationsvetenskap; Business studies;

   Sammanfattning : During the evolution of the music industry, developments in the media environment have required music firms to adapt in order to survive. Changes in broadcast radio programming during the 1950s; the Compact Cassette during the 1970s; and the deregulation of media ownership during the 1990s are all examples of changes which have heavily affected the music industry.

4. 3. Artificial intelligence in weather and climate prediction : Learning atmospheric dynamics

   Författare :Sebastian Scher; Gabriele Messori; Roberto Buizza; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Sammanfattning : Weather and climate prediction is dominated by high dimensionality, interactions on many different spatial and temporal scales and chaotic dynamics. This makes many problems in the field quite complex ones, and also state-of-the-art numerical models are - despite their immense computational costs - not sufficient for many applications. LÄS MER

5. 4. Forward Jet Production in ep-collisions at HERA

   Författare :Albert Knutsson; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Forward Jets; Parton dynamics; Jets; Small-x; Low-x; Elementary particle physics; QCD; quantum field theory; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2007:Knutsson;

   Sammanfattning : The production of forward jets has been measured in deep inelastic $ep$ collisions at HERA. The results are presented in terms of single differential cross sections as a function of the Bjorken scaling variable ($x_{Bj}$) and as triple differential cross sections $d^3 sigma / dx_{Bj}dQ^2dp_{t,jet}^2$, where $Q^2$ is the four momentum transfer squared and $p_{t,jet}^2$ is the squared transverse momentum of the forward jet.

7. 5. A Study of Parton Dynamics from Deep Inelastic Scattering Events Containing a Jet in the Forward Direction

   Författare :Martin Karlsson; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; Elementary particle physics; DIS; ep scattering; H1; jets; forward jet; small-x; parton dynamics; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2002:Karlsson;

   Sammanfattning : The DIS ep-scattering parton dynamics at low-x is characterised by an initial state cascade in which the virtualities of the propagator gluons are expected to take any kinematically allowed value, in contrast to the leading log behaviour. These dynamics might be enhanced by selecting events in which an energetic jet is found in the forward angular region at HERA, 1. LÄS MER
