2. Corrosion of Ferritic Stainless Steel Interconnects for Solid Oxide Cells – Challenging Operating Conditions
Abstract : Solid oxide cells (SOC) have the potential to revolutionize electricity production by being able to both produce electricity with very high efficiency from a variety of fuels or to produce fuels from electricity and abundant raw materials such as water or carbon dioxide. Some material challenges remain to be solved before large-scale commercialization can be achieved. READ MORE

4. Distributed File System Metadata and its Applications
Abstract : Distributed hierarchical file systems typically decouple the storage and serving of the file metadata from the file contents (file system blocks) to enable the file system to scale to store more data and support higher throughput. We designed HopsFS to take the scalability of the file system one step further by also decoupling the storage and serving of the file system metadata. READ MORE

5. Scaling Distributed Hierarchical File Systems Using NewSQL Databases
Abstract : For many years, researchers have investigated the use of database technology to manage file system metadata, with the goal of providing extensible typed metadata and support for fast, rich metadata search. However, earlier attempts failed mainly due to the reduced performance introduced by adding database operations to the file system’s critical path. READ MORE
