  1. 1. Fingerprinting digital documents

    Författare :Tina Lindkvist; Thomas Johansson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis we look at the fingerprinting problem. Our belief is that it is very difficult to prevent illegal copying, so our solution is to mark each copy uniquely so that if it is spread illegally, the original owner of that copy can be found. The principle is the same as for a serial number on a product. LÄS MER

    Sammanfattning : To facilitate early diagnosis of diseases and elucidation of the processes involved in their development and progression, various specific compounds or ‘biomarkers’ are often monitored. The first step is to decide which compounds to analyze. LÄS MER

  4. 3. Fingerprinting of digital documents

    Författare :Tina Lindkvist; Ben Smeets; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The research area of fingerprinting, or uniquely marked digital copies, is wide. We give a general model for the fingerprinting problem and point out some of the choices you need to consider before choosing the scenario for your fingerprinting system.In the following chapters we then consider specific questions in some of the possible scenarios.

  5. 4. Codes for digital fingerprinting

    Författare :Jacob Löfvenberg; James Massey; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Illegal, copying of data is a problem in many areas. Despite various efforts in copy protection and copyright enforcement the problem still exists, and with the growing use of digital means of storing and distributing data the problem seems to be getting worse. LÄS MER

  7. 5. Methods for structural studies of an antibody, screening metabolites in rat urine and analysis of spent cell cultivation media using LC/ESI-MS and chemometrics

    Författare :Leila Zamani; Sven P. Jacobsson; Jonas Bergqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Screening; Fingerprinting; metabolomics; Protein drugs; Mammalian Cell lines; LC ESI-MS; chemometrics; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : This thesis describes bioanalytical methods for generating fingerprints of biological systems for extracting relevant information with (protein) drugs in focus. Similarities and differences between samples can reveal the hidden relevant information, which can be used to optimize the production and facilitate the quality control of such protein drugs during their development and manufacture.
