1. Cost efficency of nonresponse rate reduction efforts : an evaluation approach
Sammanfattning : Nonresponse, the failure to obtain complete measurement on all sample elements, is an increasing problem in sample surveys. Efforts to reduce the nonresponse rate are expensive and their effect may not be as desired. LÄS MER
2. Integrated evaluation of resource efficiency and cost effectiveness in production systems
Sammanfattning : Improved use of resources is of enormously high relevance and crucial for achieving as well as maintaining a sustainable condition. Especially industrial production has a superior responsibility in creating a long-term viable way of living. LÄS MER
3. Efficiency Improvements in Waste-to-Energy Combustion Processes : Method Development and Evaluation
Sammanfattning : is the energy recovery method. The electrical efficiency of this technology, however, is generally low when compared with other solid fuel-fired combustion plants as a result of low steam properties. Furthermore, there is lack of efficient methods to evaluate the performance of this system. LÄS MER
4. Evaluation of Dust Suppressants for Gravel Roads : Methods Development and Efficiency Studies
Sammanfattning : Approximately 75 percent (300 000 km) of the total Swedish road network and 20 percent(20 000 km) of the national road network consists of gravel roads. One of the most significantproblems associated with gravel roads is traffic-generated dust emission, which contributes tothe deterioration of the road surface and acts as a major source of particulate matter releasedinto the atmosphere, thereby involving public economics, road safety, human health, andenvironmental quality.

5. Industrial energy efficiency improvement – the role of policy and evaluation
Sammanfattning : At EU and to a varying degree at Member State (MS) level, industrial energy efficiency improvement (EEI) is considered an attractive means for reaching political objectives of different dimensions, not least environmental. For energy-intensive manufacturing industry in particular, EEI can lead to cost reductions, improved profitability and competitiveness. LÄS MER
