Doser The difference in total widths between the B+c and B+ mesons is measured using a data sample corresponding to an integrated luminosity of 3.0 fb−1 collected by the LHCb experiment in 7 and 8 TeV centre-of-mass energy proton–proton collisi...

We present lifetime measurements of the 7D3/2 and 7D5/2 levels of Fr. We use a time-correlated singlephoton counting technique on a sample of Fr atoms confined and cooled in a magneto-optical trap. The upper state of the 7P3/2 trapping transition serves as the resonant intermediate level for two-photon excitation of the 7D states. A probe laser provides the second step of the excitation, and we...

This paper investigates whether AspectJ can be used for efficient profiling of Java programs. Profiling differs from other applications of AOP (e.g. tracing), since it necessitates efficient and often complex interactions with the target program. As such, it was uncertain whether AspectJ could achieve this goal. Therefore, we investigate four common profiling problems (heap usage, object lifeti...

A software product typically goes through many “upgrades” (version changes) over its lifetime. Reactive systems, such as email clients, software agents, proxies, traffic controllers, and telephone switches are no exception. Evolving such stateful systems is made difficult by the fact that new versions of the software must deal correctly with legacy instances. Users of earlier versions have inve...

The efficient management of the dynamic XML documents is a complex area of research. The changes and size of the XML documents throughout its lifetime are limitless.The increasing applications that use and exchange XML data is creating a demand for multi version support and store XML documents for future references. Change detection is an important part of version management to identify differe...

The exponentiated gamma (EG) distribution is one of the important families of distributions in lifetime tests. In this paper, a new generalized version of this distribution which is called Transmuted exponentiated gamma (TEG) distribution is introduced. A new distribution is more flexible and has some interesting properties. A comprehensive mathematical treatment of the TEG distribution is prov...

Materials and Methods: A cross-sectional survey was conducted in the intermediate and high schools in the Riyadh region, Saudi Arabia. The Arabic version of the International Study of Asthma and Allergies in Children (ISAAC) questionnaire tool was distributed to 568 students in the rural area and 556 students in the urban area. The factors such as lifetime, 12 months, and the severity prevalenc...

In this paper we deal with the issue of performing accurate small-sample inference in the Birnbaum– Saunders regression model, which can be useful for modeling lifetime or reliability data. We derive a Bartlett-type correction for the score test and numerically compare the corrected test with the usual score test, the likelihood ratio test and its Bartlett-corrected version. Our simulation resu...

In this paper, a generalized version of the inverted exponential distribution called the weighted inverted exponential distribution is introduced. The proposed distribution is used to analyze lifetime data. Several statistical properties of the weighted inverted exponential distribution are studied and derived. Least squares estimation, maximum likelihood estimation and Bayesian estimation meth...
