As someone who has spent the better part of two decades optimizing distributed systems—from early MapReduce clusters to ...

Heartbeat mechanism is widely used in designing high availability distributed system. In this paper, we design a multi-level heartbeat protocol, which consists of two kinds of heartbeat protocols: ...

We propose a distributed multi-aperture light field imaging system as a solution for the low resolution, small depth of field, and poor imaging quality of traditional optical field imaging systems. A ...
