2. 1. Coral Reef Habitats and Fish Connectivity : Implications for coastal management and fishery

   Author : Tove Lund Jörgensen; Michael Tedengren; Nick Graham; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; anthropogenic disturbance; coral reef habitat; fish community; coastal ecosystems; conservation management; spatial ecology; seascape perspective; holistic approach; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : Coral reefs have one of the highest levels of biodiversity of all ecosystems in the world and are important for both human livelihood and food security throughout many tropical countries. However, due to increased anthropogenic pressure on marine ecosystems, especially during the last couple of decades, coral reefs have become critically over-fished, and many reefs are now in a degraded state and are facing additional future threats due to further over-exploitation, chemical pollution, sedimentation, and effects of climate change.

4. 2. Extended mobile IP and support for global connectivity in hybrid networks

   Author : Christer Åhlund; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mobile and Pervasive Computing; Distribuerade datorsystem;

   Abstract : Mobility is an essential and necessary feature for roaming users who connect to wireless networks via access points. Access points may have different capabilities, be connected to different networks and be installed by different providers. A mobile host will discover multiple access points in this environment.

5. 3. Supporting global connectivity in heterogeneous IP networks

   Author : Christer Åhlund; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mobile and Pervasive Computing; Distribuerade datorsystem;

   Abstract : Mobility of user devices connecting to the Internet is of major interest in today's research in networking. Users with portable devices, like laptops and personal digital assistants (PDA), connecting to foreign networks in the Internet want the same functionality as when connected to the home network as well as accessibility through the home IP address.

6. 4. Seamless Millimeter-wave Connectivity via Efficient Beamforming and Handover

   Author : Sara Khosravi; Marina Petrova; Jens Zander; Riku Jäntti; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Millimeter wave networks; Beamforming; Handover; Reinforcement learning; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Extremely high data rate demands, and the spectrum scarcity at the microwave bands, make the millimeter wave (mmWave) band a promising solution to satisfy the high data rate demands in wireless networks. The main advantage of moving to the mmWave spectrum is the availability of large bandwidth. READ MORE

7. 5. Millimeter-Wave Communications for Indoor Dense Spaces : Channel Modeling and Network Deployment

   Author : Ozan Alp Topal; Cicek Cavdar; Emil Björnson; Ahmed Alkhateeb; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Millimeter wave communication; ray-tracing; channel modeling; access point deployment; convex-concave programming; reconfigurable intelligent surfaces.; Millimetervågsteknik; ray-tracing; kanalmodellering; accesspunktsutbyggnad; konvex-konkav programmering; omkonfigurerbara intelligenta yto; Informations- och kommunikationsteknik; Information and Communication Technology; Telecommunication; Telekommunikation;

   Abstract : In the ever-evolving landscape of wireless communication, the deployment of millimeter-wave (mmWave) technology has emerged as a game-changer for indoor environments. As the demand for high-speed, low-latency connectivity continues to surge, especially in densely populated areas, mmWave access point deployment has gained prominence due to its ability to deliver unprecedented data rates thanks to the available wide bandwidths.
