The Chubby lock service for loosely-coupled distributed ...

Paxos maintains safety without timing assumptions, but clocks must be introduced to ensure liveness; this over-comes the impossibility result of Fischer et al. [5, §1]. Building Chubby was an engineering effort required to fill the needs mentioned above; it was not research.

Real-Time Loop Closure in 2D LIDAR SLAM

an IMU is used to estimate the orientation of gravity for projecting scans from the horizontally mounted LIDAR into the 2D world. In our local approach, each consecutive scan is matched against a small chunk of the world, called a submap M, using a non-linear optimization that aligns the scan with the

Assuming that page layout analysis has already provided text regions of a roughly uniform text size, a simple percentile height filter removes drop-caps and vertically touching characters. The median height approximates the text size in the region, so it is safe to

BlockChain Technology

A blockchain is essentially a distributed database of records or public ledger of all transactions or digital events that have been executed and shared among participating parties. Each transaction in the public ledger is verified by consensus of a majority of the participants in the system. And, once entered, information can never be erased.
