Solid-state drive (SSD) has gain prevalence in consumer and enterprise storage markets. However, its reliability is declining with the wearing of the Flash memory. The error correcting codes (ECCs) are generally applied in SSD to cope with bit errors caused by abrasion, however, the lifetime of pages in Flash is still limited to their fixed correctability. Due to different process and usage, th...

The basic unit of testing object-oriented software is the class Bin94b, MK94]. Hence class testing corresponds in object-oriented software development to unit testing in the traditional, procedural development approach. As a rule, class testing is performed by the programmer of a class by himself and not by a seperate testing group, to decrease the need for coordination MK94]. But in these situ...

What simple learning rules can allow agents to cope with changing environments? We tested whether a rule that neglects base rates of events in the world — something that is usually considered irrational — could be as successful as Bayesian inference — the usual standard of rationality — in making cuebased predictions about events in time-varying environments. We focused on environments in which...

We present a measurement of the KL lifetime using the KLOE detector. From a sample of ∼ 4 × 108 KSKL pairs following the reaction e+e− → φ → KSKL we select ∼ 15 × 106 KL → π0π0π0 decays tagged by KS → π+π− events. From a fit of the proper time distribution we find τL = (50.92 ± 0.17stat ± 0.25syst) ns. This is the most precise measurement of the KL lifetime performed up to date. PACS: keywords:

In this work two-photon absorption laser-induced fluorescence was used to measure oxygen atom (0) concentrations in streamer discharge afterglow in a variety of fueVair mixtures in order to account for the 0 reaction pathways in transient plasma ignition. It is demonstrated that 0 atoms are generated in high concentration (~5 x 1017 cm-3) directly below the high-voltage anode in a point-to-plan...

Widely continuously tunable sources are key elements for many applications. This paper discusses the first integrated laser able to continuously tune its wavelength more than 1%: the micromechanical tunable vertical-cavity surfaceemitting laser (VCSEL). These devices have demonstrated up 19.1 nm of continuous tuning, threshold currents as low as 460 A, and powers as high as 0.9 mW. In addition ...

BACKGROUND Controlling behavior is more common and can be equally or more threatening than physical or sexual violence. This study sought to determine the role of husband/partner controlling behavior and power relations within intimate relationships in the lifetime risk of physical and sexual violence in Nigeria. METHODS This study used secondary data from a cross-sectional nationally-represe...

Accurate object lifetime prediction can be exploited by allocators to improve the performance of generational garbage collection by placing immortal or long-lived objects directly into immortal or old generations. Object-oriented software metrics are emerging as viable indicators for object lifetime prediction. This paper studies the correlation of various metrics with object lifetimes. However...

With the rise and precision of current medical procedures and the healthy lifestyles of many individuals turning towards a healthier lifestyle, the average lifetime expectancy is ever increasing [1]. Doctors are able to better diagnose and treat patients while the ability of individuals to cope and recover from illnesses is staggering. Technological advances incorporated with vast and accurate ...

Design patterns are micro architectures that have proved to be reliable, easy-to implement and robust. There is a need in science and industry for recognizing these patterns. We present a new method for discovering design patterns in the source code. This method provides a precise specification of how the patterns work by describing basic structural information like inheritance, composition, ag...
