- Detta är en avhandling från Borås : Högskolan i Borås
Sammanfattning : Heritage institutions today increasingly rely on digital formats for access, use and re-useof their collections. Books and other text-based documents, previously accessed on locationin libraries are now transferred into digital format and managed, distributed, andengaged as binary encoded representations.

2. Digital Dispersion Equalization and Carrier Phase Estimation in 112-Gbit/s Coherent Optical Fiber Transmission SystemDetta är en avhandling från Stockholm : KTH Royal Institute of Technology
Sammanfattning : Coherent detection employing multilevel modulation format has become one of the most promising technologies for next generation high speed transmission system due to the high power and spectral efficiencies. With the powerful digital signal processing (DSP), coherent optical receivers allow the significant equalization of chromatic dispersion (CD), polarization mode dispersion (PMD), phase noise (PN) and nonlinear effects in the electrical domain.

- Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis
Sammanfattning : Different wave power technologies are in development around the world in different stages of prototype testing. So far only a few devices have been deployed offshore at full scale for extended periods of time. Little data is published about how these different devices perform. LÄS MER

Sammanfattning : Mammography screening aims to reduce the number of breast cancer deaths by early detection of the disease, which is one of the leading causes of deaths for middle aged women in the western world. The risk from the x-ray radiation in mammography is relatively low but still a factor in the benefit-risk ratio of screening. LÄS MER
- Detta är en avhandling från Umeå : Umeå universitet, Institutionen för tillämpad fysik och elektronik
Sammanfattning : Most computing and communicating devices have been personal computers that were connected to Internet through a fixed network connection. It is believed that future communication devices will not be of this type. Instead the intelligence and communication capability will move into various objects that surround us. LÄS MER
