- Polycondensations of cis-9,10-epoxy-18-hydroxyoctadecanoic acid, isolated from birch outer bark, were performed at 75 degrees C in toluene as solvent and at 85 degrees C in bulk using immobilized Candida antarctica lipase B as catalyst. The polycondensation performed in toluene in presence of molecular sieves gave a polyester with DP 50 after 24 h. The same DP was obtained at much shorter reaction time (3 h) by bulk polymerization in an open vial without any drying agent present.

- WINNER is an ambitious research project aiming at identification, development, and assessment of key technologies for IMT-Advanced mobile communication systems. WINNER has devised an OFDMA-based system concept with excellent system-level performance for flexible deployments in a wide variety of operating conditions. The WINNER system provides a significant step forward from current 3G systems. Key innovations integrated into the system concept include flexible spectrum usage and relaying, adaptive advanced antenna schemes and pilot design, close to optimal link adaptation, hierarchical control signaling, and a highly flexible multiple access scheme. The end-to-end performance assessment results demonstrate that the WINNER concept meets the IMT-Advanced requirements.

- This study addresses the question of how work commutes change positive versus negative and active versus passive mood experienced after the commutes. Analyses are presented for 230 time-sampled morning commutes to work, made by 146 randomly sampled people in three different Swedish cities, asking them to use smartphones to report mood before, directly after, and later in the work place after the commute. The results show that selfreported positive emotional responses evoked by critical incidents are related to mood changes directly after the commute but not later in the day. It is also shown that satisfaction with the commute, measured retrospectively, is related to travel mode, travel time, as well as both positive and negative emotional responses to critical incidents.

CELTIC CP5-026 WINNER+, D1.4 Initial Report on Advanced Multiple Antenna Systems
- 2008
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This deliverable captures the first set of best innovative concepts identified in the field of Advanced Multiple Antenna Systems for potential inclusion into the WINNER+ system concept. The concepts consist of promising principles or ideas as well as detailed innovative techniques. For each concept, the associated benefits as well as the corresponding requirements on the system architecture and protocols, measurements and signalling, are considered. The document involves two main tracks: development of new advanced antenna schemes in the context of conventional cellular networks, and a study of coordinated multipoint transmission and reception, where multiple network nodes cooperate to enhance system performance.

CELTIC CP5-026 WINNER+, D1.8 Intermediate Report on CoMP (Coordinated Multi-Point) and Relaying in the Framework of CoMP.
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This deliverable is an intermediate report on CoMP (Coordinated Multi-Point) and on Relaying in the Framework of CoMP. It describes the second set of innovations encompassing concepts about promising principles or ideas as well as detailed innovative techniques in the framework of WINNER+ system concept. For each concept, the associated benefits as well as the corresponding requirements on the system architecture and protocols, measurements and signalling, are considered. Regarding CoMP algorithms, focus is put on schemes with reduced requirements in terms of backhauling considering two categories: “Coordinated Beamforming”, and “Joint Processing”. As for relaying, a relay-assisted interference channel, and a distributed LDPC coding for a Decode and Forward relay are introduced.
