First, tracking methods based on state estimation consider the tracking problem
as a state estimation problem and reclusively estimate the states of the tracked target, such as Kalman filter , particle filter  and so on.
The work allows the cells to physically carry a barcode as they move around, making the tracking problem
much more feasible.
Sean had previously gone to his physician and they diagnosed him with chondromalacia and a patellar tracking problem
Cummins said the equipment is going to solve the town's communication and resource tracking problem
The tracking problem
is illustrated by the fact that the first tomato-related cases of salmonella were reported in mid-April.
The Accidental Expatriate offering is our approach to solving this tracking problem
by providing information on a country by country basis, a review of management authorisation for overseas travel, policy, tax and social security consulting as well as practical tools to assist with collating the necessary data.
The suite supports local and/or remote access by system administrators; easy setup of any standard RAID configurations without interruption of server operations; full monitoring of component health via SES and SAF-TE industry standards; full logical unit mapping for easy storage allocation and partitioning; and a permanent database that provides means for tracking problem
areas, balancing storage usage and scheduling routine maintenance.
Also included is the setup of any standard RAID configuration without interruption of server operations, full monitoring of component health via SES and SAF-TE industry standards, full Logical Unit Mapping (LUN), and a permanent database that provides means for tracking problem
areas, balancing storage usage, and scheduling routine maintenance.
Coverage encompasses static optimization, optimal control of discrete-time and continuous-time systems, the tracking problem
and other LQR extensions, and final-time-free and constrained input control.
