This paper deals with the study of the impact of power supply noise on the performance of CMOS Clock and Data Recovery (CDR) Circuits. The sensitivity of the various blocks of the dual loop CDR circuit to power supply noise is first studied and then it is demonstrated that insertion of suitable Low Dropout Regulators (LDOs) can enhance the performance of the CDR system with respect to power sup...

This paper presents a modular introduction to crash-tolerant and Byzantine-tolerant protocols for reaching consensus that use the method introduced by the Paxos algorithm of Lamport and by the viewstamped replication algorithm of Oki and Liskov. The consensus protocol runs a sequence of epoch abstractions as governed by an epoch-change abstraction. Implementations of epoch and epoch-change that...

Depletion of body protein stores by means of low protein diet or plasmapheresis causes greater susceptibility to liver injury by the arsenical compound, mapharsen. Normal dogs can tolerate mapharsen in doses of 0.006 to 0.008 gm. per kilo whereas in protein-depleted dogs doses of 0.002 to 0.0025 gm. per kilo cause liver injury with jaundice. Methionine (2 to 4 gm.) given by mouth 20 to 24 hours...

In this paper, we present a novel compiler technique that provides the capability to guarantee a different memory consistency model for different variables within the same shared memory parallel program. Programmers need only focus on their parallel algorithm and which variables can tolerate the use of old values, while the compiler automatically guarantees sequential consistency for all remain...

The nature and extent of group differences in pain tolerance according to age, sex and race were examined. The method of pain tolerance determination was mechanical pressure on the Achilles tendon, performed on 41 , 119 subjects as part of the Kaiser-Permanente Automated Multiphasic Screening examination. The results showed that, on the average, a) pain tolerance decreases with age; b) men tole...

Few plan recognition algorithms are designed to tolerate input errors. We describe a case-based plan recognition algorithm (SET-PR) that is robust to two input error types: missing and noisy actions. We extend our earlier work on SET-PR with more extensive evaluations by testing the utility of its novel action-sequence representation for plans and also investigate other design decisions (e.g., ...

In this paper we show how a distributed system with synchronous processors and asynchronous message delays can be simulated by a system with both asvn chronous processors arid asynchronous rnessa.e delays in the presence of vañous types of processor faults. Consequently, the result of Fischer, Lynch and Paterson (1985), that no consensus protocol for asynchronous processors and communication ca...

In this paper, we propose to combine the fuzzy sliding mode control to tolerate actuator faults of unknown nonlinear systems subject to external disturbances. In particular, the idea of using adaptive fuzzy system to tolerate actuator faults of unknown nonlinear systems by approximating the system functions and the effects caused by actuator faults are avoided by the control structure. On the b...

In this paper, we present a strongly fault-tolerant design for the l-level k-ary tree multiprocessor and examine its reconfigurability. Our design assigns one spare node to the regular nodes of each subtree with lc levels. Moreover, spare nodes are interconnected to form a spare tree. Our approach utilizes the circuit-switched capabilities of the communication modules of the spare nodes to tole...
