1. 21. Energy Efficiency in Residential Buildings in Mozambique - Measurements and Simulations

   Författare :Gabriel Auziane; Byggproduktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy; Building; Measurements; Simulations; DEROB-LTH; Mozambique; Subtropical and Tropical climates; Energy efficiency; PV system; Electrical energy savings.;

   Sammanfattning : Mozambique, situated in south-east Africa, has sub-tropical and tropical climate and plenty of natural resources for energy production. The country is however poor, and only about 25% of the population has access to electricity from the grid. LÄS MER

3. 22. On the Quality of Computer Network Measurements

   Författare :Patrik Arlos; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Computer Network Measurements; Network Measurement Accuracy; Timestamp Accuracy; Quality of Measurements; Traffic Generation; Analysis; Sampling;

   Sammanfattning : Due to the complex diversity of contemporary Internet-services, computer network measurements have gained considerable interest during recent years. Since they supply network research, development and operations with data important for network traffic modelling, performance and trend analysis, etc. LÄS MER

4. 23. Remote Measurements of Ship Emissions

   Författare :Niklas Berg; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; airborne; Ship emissions; sulphur dioxide; nitrogen dioxide; DOAS; in situ measurements; carbon dioxide;

   Sammanfattning : The combustion of sulphur-containing fossil fuels gives rise to emissions of sulphurdioxide. Nitrogen oxides are also emitted when fuels are burned. The InternationalMaritime Organization (IMO) has ratified regulations regarding Sulphur Fuel Content(SFC) and NOx emissions from the shipping sector. LÄS MER

5. 24. Vector Measurements for Wireless Network Devices

   Författare :Efrain Zenteno; Peter Händel; Kristoffer Andersson; Magnus Isaksson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vector measurements; radio frequency; synthetic instrumentation; bandwidth extension; Järnvägsgruppen - Elsystem; Järnvägsgruppen - Elsystem;

   Sammanfattning : Wireless networks are an iconic technology of today’s modern era, theyare present in our daily activities as can be exemplified by cellular communications,wi-fi, bluetooth, and others. Vector measurements play an importantrole in the design, simulation, and testing of wireless networks and are usedto characterize key devices operating in the radio interface, such as amplifiers,filters, and mixers.
