This paper presents the semi-passive replication technique -- a variant of passive replication -- that can be implemented in the asynchronous system model without requiring a membership service to agree on a primary. Passive replication is a popular replic ...
The CORBA Object Group Service (OGS) is a new CORBA service that provides support for fault-tolerance through the replication of CORBA objects. In this paper, we present several optimization techniques that are used to improve the performance of OGS. For e ...
Cosine-modulated filter banks (CMFB’s) are filter banks whose impulse responses are obtained by modulating a window with cosines. Among their applications are video and audio compression and multitone modulation. Their continuous- time counterpart is known ...
Hydrogen prodn. from toluene by steam reforming, partial oxidn. and autothermal reforming was studied by step-response method in a tubular fixed-bed reactor, at temps. between 550 Deg-700 Deg. Nickel in the form of a wire grid is a valuable catalyst, where ...
Theoretical and experimental work on the vertical position control system on the COMPASS-D tokamak is described. An analog proportional + derivative (P + D) system is currently used, and two important sources of disturbance are observed in the system. One ...
Perfect reconstruction oversampled filter banks are equivalent to a particular class of frames in t(2)(Z), These frames are the subject of this paper. First, necessary and sufficient conditions on a filter bank for implementing a frame or a tight frame exp ...
A miniaturised Total chemical Analysis System (μTAS) for glucose and lactate measurement in biological samples constructed based on an integrated microdialysis sampling and detection system. The complete system incorporates a microdialysis probe for intrav ...
An alternative structure for adaptive linear prediction is proposed in which the adaptive filter is replaced by a cascade of inde- pendently adapting, low-order stages, and the prediction is generated by means of successive refinements. When the adaptation ...
By extending the system theory under the (min,+)-algebra to the time varying setting, we solve the problem of constrained traffic regulation and develop a calculus for dynamic service guarantees. For a constrained traffic regulation problem with maximum to ...
A theoretical approach to the current vs. time behavior of arrays of hemispherical or disc-shaped microelectrodes is presented. The treatment includes the chronoamperometric response to changes of the applied potential, and the dynamic response to changes ...
