3. 2. Energy efficient Ericsson Many-Core Architecture (EMCA) IP blocks for 5G ASIC

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Zilin Zhang; [2021]
   Nyckelord :Technology and Engineering;

   Sammanfattning : Power consumption has become a leading concern for SoC aimed at 5G products that demand increased functionality, smaller form factors, and low energy footprint. For some EMCA IP blocks a hierarchical clock gating mechanism ensures coarse-grained power savings based on actual processing need but for many blocks this approach cannot be employed. LÄS MER

7. 5. Validation of a Cleanup Method for Analysis of Novel Brominated Flame Retardants in Biota Matrices Sofie Björklund 2015-05-30 Supervisors Ingrid Ericson

   Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

   Författare :Sofie Björklund; [2015]
   Nyckelord :Novel Brominated Flame Retardants; cleanup method; multilayer silica column; biota matrices;

   Sammanfattning : Brominated flame retardants is a group of compounds present in numerous types of materials in our surroundings. Although their purpose is to slow the progression of a fire, many has been shown to be toxic to the environment. Novel brominated flame retardants have been introduced to the market as old ones have been removed. LÄS MER
