Performance of the double-LIE architecture

Bilgen, Semih
Salamah, M
The Double-LIB is an ATM-based switch architecture we have proposed for distributed memory multiprocessor systems. It is essentially a development of the Limited Intermediate Buffer (LIB) idea which was originally proposed to overcome the drawbacks of input and output buffered ATM switches. In this paper, we summarize the characteristics of the Double-LIB and then proceed to report some simulation-based performance results. It is our conclusion that the Double-LIB switch is promising as a solution to the distributed memory multiprocessor communication problem.


Efficient Abstractions for the Supervisory Control of Modular Discrete Event Systems
Schmidt, Klaus Verner (2012-12-01)
The topic of this technical note is the nonblocking and maximally permissive abstraction-based supervisory control for modular discrete event systems (DES). It is shown, that an efficient abstraction technique, that was developed for the nonconflict verification of modular DES, is also suitable for the nonblocking supervisory control. Moreover, it is proved that this abstraction technique can be extended by the condition of local control consistency, in order to achieve maximally permissive supervision. Dif...
Nonblocking hierarchical control of decentralized des
Schmidt, Klaus Verner; Moor, Thomas (null; 2005-12-01)
This work considers a hierarchical control architecture for a class of discrete event systems which can also be applied to decentralized control systems. It is shown that nonblocking supervisory control on the high level of the hierarchy results in nonblocking and hierarchically consistent control on the low level. Copyright © 2005 IFAC.
Fuzzy Hybrid Systems modeling with application in decision making and control
Boutalis, Yiannis; Moor, Thomas; Schmidt, Klaus Verner (2012-11-28)
Hybrid Systems are systems containing both discrete event and continuous variable components. Many recent contributions address crisp situations, where ambiguity or subjectivity in the measured data is absent. In this paper, we propose Fuzzy Hybrid Systems to account for inaccurate measurements and uncertain dynamics. We present a strategy to determine the most appropriate control actions in a sampled data setting. The proposed approach is based on three basic steps that are performed in each sampling perio...
Concurrency control in distributed databases through time intervals and short-term locks
Halıcı, Uğur (Institute of Electrical and Electronics Engineers (IEEE), 1989)
A method for concurrency control in distributed database management systems that increases the level of concurrent execution of transactions, called ordering by serialization numbers (OSN), is proposed. The OSN method works in the certifier model and uses time-interval techniques in conjunction with short-term locks to provide serializability and prevent deadlocks. The scheduler is distributed, and the standard transaction execution policy is assumed, that is, the read and write operations are issued contin...
Computational fluid dynamics analysis of store seperation
Demir, H. Özgür; Alemdaroğlu, Hüseyin Nafiz; Department of Aerospace Engineering (2004)
In this thesis, store separation from two different configurations are solved using computational methods. Two different commercially available CFD codes; CFD-FASTRAN, an implicit Euler solver, and an unsteady panel method solver USAERO, coupled with integral boundary layer solution procedure are used for the present computations. The computational trajectory results are validated against the available experimental data of a generic wing-pylon-store configuration at Mach 0.95. Major trends of the separation...
