ABSTRACT
The authors study different two way synchronization methods between a server and distributed clients. Client-server architectures are used to control multiple instances from center. Hard-coded embedded controllers are replaced by embedded controllers based on general purpose operation systems. Authors aims to find the best synchronization method to exhange data between a HVAC system and a server. The synchronization is tested using different methods: online file storage, database, ftp, mail and web-service. The system based on online file storage was implemented in a city in Holland to control a HVAC system. The embedded controller receives data from the server to perform better control and increase economical efficiency of the HVAC system. All synchronization methods discussed in the paper can be implemented in other domains.

Fuzzy Immune PID Temperature Control of HVAC Systems
ISNN 2009: Proceedings of the 6th International Symposium on Neural Networks: Advances in Neural Networks - Part IIIn this paper, a new nonlinear fuzzy-immune proportional-integral derivative (PID) controller is proposed. This controller consists of a PID controller and a basic immune proportional controller in cascaded connection, the nonlinear function of the ...
PASS: A Hybrid Storage System for Performance-Synchronization Tradeoffs Using SSDs
ISPA '12: Proceedings of the 2012 IEEE 10th International Symposium on Parallel and Distributed Processing with ApplicationsRecent advances in flash memory show great potential to replace traditional hard drives (HDDs) with flash-based solid state drives (SSDs) from personal computing to distributed systems. However, it is still a long way to go before completely using SSDs ...
Two-phase synchronization with sub-cycle latency
Synchronizers typically incur long latency of multiple-clock cycles, resulting in low throughput. This paper presents two novel fast synchronizers, both based on two-phase protocols: a two-flip-flop synchronizer which reduces the data cycle from 6-12 ...
