Software fault-tolerance techniques have been widely used in computing systems to achieve high level of quality. Rejuvenation, a modern software fault-tolerance technique, has attracted a large number of researchers in software engineering area. Evaluating the effectiveness and feasibility of this technique becomes extremely important in selecting, comparing and applying it in actual software s...

Waste cooking oil (WCO), in many cases, can rejuvenate aged asphalt and restore its properties. However, the influence of WCO qualities on rejuvenation behaviors of aged asphalt has not been investigated in detail. The objective of this paper was to evaluate the effects of WCO viscosity and acid value on the basic, rheological, and chemical properties of a typical rejuvenated asphalt. Penetrati...

Since the introduction of the technique reported by Skoog [1] and the study of Mitz and Peyronie [2] regarding the superficial musculoaponeurotic system (SMAS), the concept of facial rejuvenation has entered a new phase, going beyond the conventional subcutaneous facelift technique. However, Mitz and Peyronie [2] focused on the SMAS layer lateral to the zygomaticus major muscle—in other words, ...

In this paper we address the problem of preventive maintenance of operational software systems, an approach recently proposed to counteract the phenomenon of software \aging". We consider the so-called \software rejuvenation" technique 13], which consists in periodically stopping the software system and then restarting it in a \robust" state after a proper maintenance, and we propose a methodol...

Skin rejuvenation has developed into one of the most popular indications for laser and intense pulsed light (IPL) treatment in dermatology. During the past few years, nonablative skin rejuvenation with infrared lasers has become ever more popular. The results for hyperpigmentation, telangiectasias and erythema are very good, whereas the results in treating wrinkles are not as good as with ablat...

Recognizing that the tide was changing in dentistry, my wife Janet — also a dentist — and I decided to include facial rejuvenation procedures into our practice’s “smile design” treatment. Our most exciting adventure to date has been the opening of a dental and facial rejuvenation/esthetic dentistry center, appropriately named, “A Smile Above.” We are enjoying the practice of dentistry more toda...

1. Introduction The widespread phenomenon of software (image) aging is known to cause performance degradation, transient failures or even crashes of applications. This undesired behavior is especially visible in long-running software such as web and application servers and enterprise always-on applications-software deployed frequently in Grid and utility computing environments. The management c...

In this paper, we use software rejuvenation as a preventive and proactive fault-tolerance technique to maximize the level of reliability for continuous and safety critical systems. We take both transient faults caused by software aging effects and network transmission faults into consideration and mathematically analyze the optimal software rejuvenation period that maximizes system’s reliabilit...
