1. 1. High-Resolution Seismics Methods Applied to Till Covered Hard Rock Environments

   Författare :Björn Bergman; Christopher Juhlin; Laust Börsting Pedersen; Ari Tryggvason; Ramon Carbonell; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; High-Resolution; Reflection Seismics; Tomography; Nuclear waste repository; Bedrock; Sediments; Geofysik; Geophysics; Geofysik;

   Sammanfattning : Reflection seismic and seismic tomography methods can be used to image the upper kilometer of hard bedrock and the loose unconsolidated sediments covering it. Developments of these two methods and their application, as well as identifying issues concerning their usage, are the main focus of the thesis. LÄS MER

3. 2. Using Multicoloured Halftone Screens for Offset Print Quality Monitoring

   Författare :Lars Bergman; Björn Kruse; Antanas Verikas; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datorteknik; multicolour printing; printing process; colour images; colour impression; CCD-camera; Datorteknik; Computer engineering; Datorteknik;

   Sammanfattning : In the newspaper printing industry, offset is the dominating printing method and the use of multicolour printing has increased rapidly in newspapers during the last decade. The offset printing process relies on the assumption that an uniform film of ink of right thickness is transferred onto the printing areas. LÄS MER

4. 3. Bit loading and precoding for MIMO communication systems

   Författare :Svante Bergman; Björn Marklund; Tim Davidsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

   Sammanfattning : This thesis considers the joint design of bit loading, precoding and receive filters for a multiple-input multiple-output (MIMO) digital communication system. Both the transmitter and the receiver are assumed to know the channel matrix perfectly. It is well known that, for linear MIMO transceivers, orthogonal transmission (i.e. LÄS MER

5. 4. Payment Efficiency and Payment Pricing : Four Essays

   Författare :Magnus Willesson; Ted Lindblom; Björn Lantz; Mats Bergman; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; payments; bank; efficiency; pricing; technical change; two-sided networks; price bundling; Payments; bank; efficiency; pricing; technical change; two-sided networks; price bundling;

   Sammanfattning : The four essays in this Doctoral thesis provide new evidence of efficiency in electronic payments and banks due to the technological change in payment distribution systems and how banks can utilize and develop their pricing of payments in the presence of changing technology.“Benefits from a Changing Payment Technology in European Banking” identifies cost savings from technical change in European banking.

7. 5. Regularity and boundary behavior of solutions to complex Monge–Ampère equations

   Författare :Björn Ivarsson; Zbigniew Blocki; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Complex Monge--Ampère operator; interior regularity; plurisubharmonic function; blow-up rate of solutions; bounded plurisubharmonic exhaustion function; globally Lipschitz; strongly pseudoconvex domain; hyperconvex domain; Bergman kernel; MATEMATIK; MATHEMATICS; MATEMATIK; matematik; Mathematics;

   Sammanfattning : In the theory of holomorphic functions of one complex variable it is often useful to study subharmonic functions. The subharmonic can be described using the Laplace operator. When one studies holomorphic functions of several complex variables one should study the plurisubharmonic functions instead. LÄS MER
