NFS is a distributed file system which is widely used in UNIX environments. Many studies have been worked to improve its I/O performance and scalability. However, existing architectures, which have either single load balancer or meta server, could suffer from single-pointof-failure and unnecessary network delay. We propose a new NFS architecture called mNFS cluster to improve its scalability. E...

Data center networks are designed for satisfying the data transmission demand of densely interconnected hosts in the data center. The network topology and routing mechanism can affect the performance and latency significantly. Nowadays, the fat-tree network is one of the most widely used topologies for data center networks. Network engineers also adopt load balancing methods in the design of ro...

PurposeSoft tissue balancing is an important step in a total knee procedure, carried out manually, or using indicator. The purpose of this study was to evaluate our design 3D printed Balancer, and demonstrate how it could be used at surgery.ProceduresWhen inserted between the femur tibia, Balancer displayed forces acting across lateral medial compartments, indicated by pointers end handle. A lo...
