1. 1. High Capacity Fiber-Connected Wireless MIMO Communication

   Författare :Husileng Bao; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; central unit; Radio-over-Fiber; millimeter-wave.; multiple-inputmultiple- output; remote radio head;

   Sammanfattning : There will be more and more users while beyond-5G (B5G) and 6G bring more wireless applications. Current cellular communication networks assign specific serving boundaries for each radio, which becomes a limitation when too many users work with one radio simultaneously. By physically distributing radios. user’s service can be more uniform. LÄS MER

3. 2. Investigation of Sigma-Delta-over-Fiber for High-Capacity Wireless Communication Systems

   Författare :Husileng Bao; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; millimeter-wave; multipleinput- multiple-output; remote radio head; Radio-over-fiber; central unit;

   Sammanfattning : The advent of beyond-5G (B5G) and 6G technologies brings increases in wireless devices and their applications. Although massive multiple-input-multiple-output (MIMO) delivers high-capacity services using co-located MIMO (CMIMO) technology, distributed MIMO (D-MIMO) technology offers a more uniform user service.

4. 3. The metamorphic history of Naxos (central Cyclades, Greece) : Deciphering the Oligocene and Miocene exhumation events

   Författare :Alexandre Peillod; Uwe Ring; Alasdair Skelton; Arne Willner; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cycladic Blueschist Unit; exhumation; fluid flow; geothermobarometry; Hellenide orogen; Rb-Sr dating; subduction-zone metamorphism; Heat flow; Lower crust; extensional domain; Metamorphic core complex; Geology; geologi;

   Sammanfattning : High pressure, low temperature (HP-LT) rocks observed at the surface of the Earth are evidence ofpast subduction zones. Understanding the tectonics processes that control the exhumation of HP-LT metamorphic rocks in these subduction zones requires full comprehension of the pressure-temperature-time (P–T–t) cycle that the rocks experienced.

5. 4. Bebyggelsemönster i medelhavsområdet: en studie av medinan i Fes ställd i relief mot Siena|

   Författare :Abdellah Abarkan; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; community unit; Mediterranean; space analysis; physical structure; medieval; quarter; primary pattern unit; Siena; urban pattern; medina of Fes;

   Sammanfattning : This thesis is an analysis and comparative study of medieval Mediterranean urban patterns. With urban patterns is meant the arrangement of houses and public spaces with special regard to the relations between them. The thesis contains four parts. Previous research on Muslim cities is described and commented in the first part. LÄS MER

7. 5. Acquired or inherited prestige? : molecular studies of family structures and local horses in Central Svealand during the Early Medieval period

   Författare :Anders Götherström; Mark G. Thomas; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; ancient DNA; boat cemeteries; Early Medieval Period; Central Svealand; bone preservation; inheritance; acquired status; inherited status; arkeologi; Archaeology;

   Sammanfattning : This is a study of the role of inheritance among the élite in Early Medieval central Svealand and the possibility to study it by molecular genetic methods. The study is a part of the research project Svealand in the Vendel and Viking periods (SIV). The study rests on classical as well as a new type of source material. LÄS MER
