1. 31. Applications of artificial neural networks for time series data analysis in energy domain

   Författare :Fan Zhang; Hasan Fleyeh; Stawomir Nowaczyk; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Deregulated energy market; electricity prices; district heating; energy efficiency; neural networks; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

   Sammanfattning : With the development of artificial intelligence techniques and increased installation of smart meters in recent years, time series analysis using historical data in the energy domain becomes applicable. In this thesis, microdata analysis approaches are used, which consist of data acquisition, data processing, data analysis and data modelling, aiming to address two research problems in the energy domain.

3. 32. Industrial Ecology Approaches to Improve Metal Management : Three Modeling Experiments

   Författare :Rajib Sinha; Björn Frostell; Maria Malmström; Amir Rashid; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system dynamics; element flow analysis; industrial ecology; product systems; end-of-life; DPSIR; pressure-based driver-oriented approach; environmental management; Industrial Ecology; Industriell ekologi;

   Sammanfattning : A linear model of consumption − produce-use-dispose − has constantly increased the pressure on the environment in recent decades. There has been a great belief that technology will solve the problem, but in many cases it is only partly contributing to the solution. For a full solution, the root causes of problems need to be identified. LÄS MER

4. 33. On Sustainability in Local Energy Planning

   Författare :Farhad Derakhshan; Energihushållning; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Indicators; Sustainable Development; Energy Systems; Energy Planning;

   Sammanfattning : Energy is among the main driving forces needed for sustainable development. Provision of energy services, from the supply side to transmission/distribution and use, must include management, and good management requires tools. Energy planning is a tool for managing the community energy system through assessing and balancing supply and demand. LÄS MER

5. 34. The social organization of energy efficiency in shipping: a practice-based study

   Författare :Martin Viktorelius; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Activity theory; Energy efficiency; Energy consumption; Knowing-in-practice; Shipping; Practice theory; Practice based studies; Energy management; Work;

   Sammanfattning : The central research question explored in this study is how energy efficiency is organized onboard large merchant ships. The dominant techno-economical approach within energy research and policy, in general, and shipping research and policy, in particular, is reviewed and criticized as being too limited for understanding the challenges and opportunities related to the organization and management of energy efficiency in shipping companies.

7. 35. 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
