1. 11. Structure and Dynamics in Transition Metal Perovskites — An Optical Spectroscopy Study

   Författare :Johan Bielecki; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multiferroics; colossal magnetoresistance; magnetism; proton-conduction; spin-state transition; structure; Ultrafast spectroscopy; high temperature superconductivity; dynamics; Raman;

   Sammanfattning : Transition metal oxides with the perovskite structure exhibit a vast number of exotic properties due to the large number of competing degrees of freedom at the Fermi surface. Together with couplings between and correlations within these degrees of freedom, this class of materials is of high interest from both a practical and theoretical point of view. LÄS MER

3. 12. Att kontrollera staten : Den statliga revisionens roll i den parlamentariska demokratin : [the role of the state audit in a parliamentary democracy]

   Författare :Shirin Ahlbäck; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political science; Audit; accountability; responsibility; Parliamentary Auditors; National Audit Office; democratic theory; performance audit; public administration; Statsvetenskap; Political science; Statsvetenskap; Statskunskap; Political Science;

   Sammanfattning : The theoretical point of departure in this dissertation is that even though a main thread in classical and modem democratic theory deals with the idea of accountable government, this discussion suffers from two inadequacies. Firstly, in addition to the requisites of accessible knowledge about who is responsible, and the presence of institutional mechanisms for holding someone accountable (e. LÄS MER

4. 13. Design, analysis and simultion for optical access and wide-area networks

   Författare :Jiajia Chen; Lena Wosinska; Hussein Mouftah; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber access networks; passive optical network; dynamic bandwidth allocation; reliability; switched optical networks; switching node; optical circuit switching; optical packet switching; routing and wavelength assignment; security; Telecommunication; Telekommunikation;

   Sammanfattning : Due to the tremendous growth of traffic volume caused by both exponential increase of number of Internet users and continual emergence of new bandwidth demanding applications, high capacity networks are required in order to satisfactorily handle the extremely large amount of traffic. Hence, optical fiber communication is the key technology for the network infrastructure. LÄS MER

5. 14. Provisioning Strategies for Transparent Optical Networks Considering Transmission Quality, Security, and Energy Efficiency

   Författare :Amornrat Jirattigalachote; Lena Wosinska; Paolo Monti; Biswanath Mukherjee; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transparent optical networks; routing and wavelength assignment; physical-layer impairments; signal quality; differentiation of services; physical-layer attacks; power equalizers; Greedy Randomized Adaptive Search Procedure GRASP ; green networks; energy awareness; dedicated path protection; shared path protection; survivable WDM networks;

   Sammanfattning : The continuous growth of traffic demand driven by the brisk increase in number of Internet users and emerging online services creates new challenges for communication networks. The latest advances in Wavelength Division Multiplexing (WDM) technology make it possible to build Transparent Optical Networks (TONs) which are expected to be able to satisfy this rapidly growing capacity demand.

7. 15. Phosphonamidates as potential NDM-1 inhibitors

   Författare :Katarzyna Palica; Mate Erdelyi; Lindon Moodie; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : WHO’s recent reports indicate that the rapidly growing resistance of bacteria became one of the biggest problems of the XXI century. The most powerful human counter weapon, antibiotics, starts to become ineffective for the treatment of bacterial infections. LÄS MER
