Structural fault tolerance (SFT) is the ability of a multiprocessor to reconfigure around faulty processors or links in order to preserve its original processor interconnection structure. In this paper, we focus on the design of SFT multiprocessors that have low switch and link overheads, but can tolerate a very large number of processor faults on the average. Most previous work has concentrate...

P redictability is a measure of how accurately we can forecast a future event. 100% predictability is synonymous with omnipotence, 0% with having no clue whatsoever. Analog devices generally provide good levels of predictability. For example, manufacturers sell light bulbs with MTTF (mean time to failure) scores. A car traveling at 40 mph will still be traveling at a speed plus or minus some sm...

The eeect of non-catastrophic (or soft) defects (i.e., neither short nor open) on long interconnection lines is analyzed and an estimate is derived for the frequency-dependent critical area for such lines. The analysis is based on a transmission-line model of interconnection lines, and the reeections caused by the defect are taken into account. This analysis results in an estimated prediction o...

TETs are rare malignancies of the anterior mediastinum ranging from more indolent thymoma (T) to aggressive thymic carcinoma (TC). There is no standard treatment after platinum-based chemotherapy in refractory setting. A phase II trial reported clinical benefit for everolimus (EVE) 10mg (DCR 88%). EVE has immune modulatory activity, interest patients (pts) with auto-immune disorders (AIDs), det...

A variety of impressive approaches to legged locomotion exist; however, the science of legged robotics is still far from demonstrating a solution which performs with a level of flexibility, reliability and careful foot placement that would enable practical locomotion on the variety of rough and intermittent terrain humans negotiate with ease on a regular basis. In this thesis, we strive toward ...

It is time for the systems community of researchers and developers to broaden the agenda beyond performance. The 10000X increase in performance over the last 20 years means that other aspects of computing have risen in relative importance. We see three challenges for the future as [Patterson2002a]: 1. Synergy with humanity: We need to make the technology match human nature, both for users of pe...

Distributed systems, especially those providing cloud services, endeavor to construct sufficiently reliable storage in order to attract more customers. Generally, pure replication and erasure code are widely adopted in distributed systems to guarantee reliable data storage, yet both of them contain some deficiencies. Pure replication consumes too much extra storage and bandwidth, while erasure ...

Thanks to the growing sophistication of artificial agent technologies, businesses will increasingly face decisions of whether to have a human employee or artificial agent perform a particular function. This makes it desirable to have a common temporal measure for comparing the work effort that human beings and artificial agents can apply to a role. Existing temporal measures of work effort are ...

This investigation deals with the transient analysis of the machine repair system consisting of M-operating units operating under the care of single repairman. To improve the system reliability/availability, Y warm standby and S cold standby units are provided to replace the failed units. In case when all spares are being used, the failure of units occurs in degraded fashion. In such situation ...

This paper deals with the transient analysis of K-out-of-N: G system consisting of Noperatingmachines. To improve system reliability, Y cold standby and S warm standbys spares areprovided to replace the failed machines. The machines are assumed to fail in multiple modes. At leastK-out-of-N machines for smooth functioning of the system. Reliability and mean time to failure areestablished in term...
