1. 6. Assessment of Daylighting and Electric Lighting Performance in a Retrofitting Project: A Case Study in Sweden

   Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign

   Författare :Xueting Wang; [2017]
   Nyckelord :Daylighting Assessment; Electric Lighting Assessment; Field Measurement; Lighting Simulation; Daylight Factor; Daylight Glare Probability; Technology and Engineering;

   Sammanfattning : Newly constructed building stocks have been decreasing in last decades; thus, renovation and retrofitting represent a large amount of opportunities to upgrade the building performance and energy efficiency of building assets in their life span, as well as to reduce greenhouse gas emissions. An overall assessment of a lighting retrofit project can support to judge the quality of a retrofit as good or bad and evaluate the application of a retrofit measure in practice, as well as provide quantitatively based cases for future implementations.

3. 7. Ray-tracing based analysis of channel characteristics and capacity improvement capabilities of spatial multiplexing and beamforming at 15 and 28 GHz

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

   Författare :Qingbi Liao; [2016]
   Nyckelord :5G; 15 GHz; 28 GHz; beamforming; capacity; channel multiplexing richness; hybrid beamforming; MIMO; mm-Wave; ray-tracing; spatial multiplexing; Technology and Engineering;

   Sammanfattning : In the previous decades, mm-Wave frequency bands have largely been ignored for cellular communication because of the high free space attenuation as well as the cost and complexity of mm-Wave RF circuits. However, with the improvement of RF and antenna technologies over the last decade, it has become feasible to con- sider mm-Wave bands for cellular communications. LÄS MER

4. 8. Klimatzonen : vintersval trädgård i kontorsbyggnad

   Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

   Författare :Lisa Carlsson; [2014]
   Nyckelord :medelhavsklimat; vintersval trädgård; kontorsbyggnad; inomhusmiljö; subtropiskt klimat; medelhavsväxter; inomhusväxter; interiorscape;

   Sammanfattning : I en inglasad miljö kan vi skapa ett annat klimat än det som råder utomhus vilket gör det möjligt att odla ett annat växtmaterial än det vi har i våra trädgårdar. Växter från exotiska platser skapar intressanta miljöer i vintermörkret. LÄS MER

5. 9. 3G Transmission Energy Savings through Adaptive Traffic Shaping Policies

   Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap; Linköpings universitet/Tekniska högskolan

   Författare :Henning Hall; Christian Luckey; [2014]
   Nyckelord :;

   Sammanfattning : This bachelor thesis will explore how two traffic shaping mechanisms can help preserve battery power while retaining a certain Quality of Service (QoS) in an Android based application developed for crisis management. The implemented user-space mechanisms will delay all elastic data requests in order to reduce the number of times the 3G transmission radio enters high power states. LÄS MER

7. 10. Assessing the Vulnerability of DTN Data Relaying Schemes to Node Selfishness

   Master-uppsats, Institutionen för informationsteknologi

   Författare :Shyam Sundar Balasubramanian; [2012]
   Nyckelord :DTN; selfish nodes; ONE simulator;

   Sammanfattning : The main principle behind the working of delay tolerant networks (DTN) is the mobility of the nodes along with their contact sequences for exchanging data. Nodes which are a part of the DTN network can behave selfishly due to network reservation policy, especially when constrained to energy or storage space. LÄS MER
