Sampling and sampled-data models

Proceedings of the 2010 American Control Conference, 2010
Physical systems typically evolve continuously whereas modern controllers and signal processing devices invariably operate in discrete time. Hence sampling arises as a cornerstone problem in essentially all aspects of modern systems science. This paper reviews various aspects of sampling of signals and systems.

On sampling regional data

Data & Knowledge Engineering, 1997
Summary: The region quadtree is a very popular hierarchical data structure for the representation of binary images (regional data) and it is heavily used at the physical level of many spatial databases. Random sampling algorithms obtain approximate answers of aggregate queries on these databases efficiently.

Sampling for big data

Proceedings of the 20th ACM SIGKDD international conference on Knowledge discovery and data mining, 2014
One response to the proliferation of large datasets has been to develop ingenious ways to throw resources at the problem, using massive fault tolerant storage architectures, parallel and graphical computation models such as MapReduce, Pregel and Giraph. However, not all environments can support this scale of resources, and not all queries need an exact

Invariance of sampled-data and adaptive sampled-data systems

IFAC Proceedings Volumes, 1963
Summary In the report it is shown that the invariance conditions can be used successfully in usual continuous control systems and also in sampled- data control systems. This is especially important in adaptive impulse systems. In the first section of the report fundamentals of invariance theory of combined sampled-data systems are considered.
