1. Improved road design for future maintenance : analysis of road barrier repair costs
Sammanfattning : The cost of a road construction over its service life is a function of the design, quality of construction, maintenance strategies and maintenance operations. Unfortunately, designers often neglect a very important aspect which is the possibility to perform future maintenance activities. LÄS MER
2. Heterostructure barrier varactors
Sammanfattning : .... LÄS MER
3. The bentonite barrier : microstructural aspects on colloid filtration and radiation effects on bentonite colloid stability
Sammanfattning : In many countries a multi-barrier concept in a deep geological repository is planned for final disposal of nuclear waste. Many of these different concepts, for example the Swedish KBS-3 model, include an engineered barrier consisting of compacted bentonite. LÄS MER
4. Thermal Barrier Coatings : Durability Assessment and Life Prediction
Sammanfattning : Thermal barrier coating (TBC) systems are coating systems containing a metallic bond coat and a ceramic top coat. TBCs are used in gas turbines for thermal insulation and oxidation resistance. LÄS MER
5. Thermal Barrier Coatings : Failure Mechanisms and Life Prediction
Sammanfattning : Thermal barrier coatings (TBCs) use in the hot sections of gas turbine engine enables them to run at higher temperatures, and as a consequence, achieve higher thermal efficiency. For full operational exploitation of TBCs, understanding their failure and knowing the service life is essential. LÄS MER
