Content distribution networks (CDNs) are a recent development to improve the performance of networked applications. The design of replica placement algorithms is one of the foremost problems in CDNs. Current replica placement methods do not guarantee a bound on the maximum latency to any client. In this paper, we propose several algorithms for replica placement with latency constraints. The alg...

The analysis of behavior began with a form of data, rate of responding, which allowed for efficient study and for the description of the basic principles of behavior. Especially important were the facts that rate of responding was a direct reflection of fundamental properties of behavior, and that rate of responding was measured continuously within an experimental session. As behavior analysts ...

The design of an optical current sensor to be used in a pulsed power generator is presented. The current sensor is based on the polarization rotation by the Faraday effect. GEPOPU is a pulsed power generator, 110 kA, 120 ns double transit time, 1.5 Ω coaxial geometry, and current rise time of 50 ns. Two different optical geometries surrounding the conductor were tried, using Amici roof prism an...

This paper reports a noncontact inspection method, using Pulsed Eddy Current (PEC) stimulated thermography, for the evaluation of the anisotropic dependency of electrical conductivity of steel exposed to tensile stress. This method combines microscope lens based thermography with PEC using a rectangular excitation coil, giving directional excitation, to infer the electromagnetic properties vari...

We perform a model-independent analysis of solar neutrino flux rates including the recent charged-current measurement at the Sudbury Neutrino Observatory (SNO). We derive a universal sum rule involving SNO and SuperKamiokande rates, and show that the SNO neutral-current measurement cannot fix the fraction of solar nu(e) oscillating to sterile neutrinos. The large uncertainty in the standard sol...

measuring individual talent is a prerequisite of talent management. in order to do so, there are methods which have been established such as intelligence tests, general and individual tests, ratings scale and the literature of educational performance. applying these methods are effective, if measurement error is low and validity is high. all current available methods are faced with issues relat...

The objective of the current investigation is to replicate the results of a previous study on subgrouping of poor readers. One important aim of the study to be replicated was to develop tools, not only for identifying poor readers, which is a rather straightforward task, but also for examining the pattern of poor reading based on a theoretical analysis of the reading process. Eight distinct sub...

Article history: Received 9 September 2016 Received in revised form 3 February 2017 Accepted 4 February 2017 Available online 6 February 2017 Contact between adoptive families and birth families in the context of intercountry adoption, as well as adoption by sexual minorities (e.g., lesbians and gay men), represent understudied topics. In the current study, we examine the extent and type of con...

Background & Aims: Two famous methods are commonly used for the measurement of carpal height ratio. Both methods are performed on anteroposterior radiogram and have some shortcomings. We are going to introduce a new method for measuring this index in lateral view of the wrist radiogram' Methods: This cross-sectional and case-control study was conducted on 100 anteroposterior and lateral radiogr...
