The IT industry needs systems management models that leverage available application information to detect quality of service, scalability and health of service. Ideally this technique would be common for varying application types with different n-tier architectures under normal production conditions of varying load, user session traffic, transaction type, transaction mix, and hosting environmen...

Automatic image quality assessment has many diverse applications. Existing quality measures are not accurate representatives of the human perception. We present a hybrid image quality (HIQ) measure, which is a combination of four existing measures using an ‘n’ degree polynomial to accurately model the human image perception. First we undertook time consuming human experiments to subjectively ev...

We present the results of a high angular resolution (0. 3 ≈ 40AU) Submillimeter Array survey of the 345GHz (870μm) thermal continuum emission from 9 of the brightest, and therefore most massive, circumstellar disks in the ∼1Myr-old Ophiuchus starforming region. Using two-dimensional radiative transfer calculations, we simultaneously fit the observed continuum visibilities and broadband spectral...

Recently, provisioning a fast handoff in IEEE 802.11 Wireless Local Area Network (WLAN) has been an attractive research issue since the incurring latencies are unsatisfactory to support today’s fast emerging realtime services with stringent Quality of Service (QoS) requirements. The 802.11 handoff consists of (1) scanning, (2) authentication, and (3) reassociation. Particularly, the scanning ha...

Nowadays, geographical resources (both data and applications) are increasingly being accessible via search engines or web services. As a consequence, users must choose among a set of available resources the ones that best fit their needs. However, users neophytes are currently unable to determine a priori (i.e., before acquisition and use), whether a resource is adequate for its intended usage....

Recently, a number of methods and techniques for assessing the quality of software product lines have been proposed. However, to the best of our knowledge, there is no study which summarizes all the existing evidence about them. This paper presents a systematic review that investigates what methods and techniques have been employed (in the last 10 years) to evaluate the quality of software prod...

This supplement consists of several parts that refer directly to specific topics in the paper: A Proof of Equation (2) B Proof of Lemma 3.1 (Symmetric biproportional fit) C Technical details on why ”local affinity” is sufficient in Section 4.1 D Proof of Theorem 4.2 (Convergence of PSIPF) E Proof of Lemma 4.4 (L1-monotony) F Proof of Lemma 4.5 (Volume bounds) G Proof of Lemma 4.6 (Limit points)...

The Ephyra QA system has been developed as a flexible open-domain QA framework. This framework allows us to combine several techniques for question analysis and answer extraction and to incorporate multiple knowledge bases to best fit the requirements of the TREC QA track, in which we participated this year for the first time. The techniques used include pattern learning and matching, answer ty...

Several commercial instruments are available for pressure measurements. As per ISO stipulations, whenever such instruments are used for precise and accurate pressure measurements, it is obligatory on the part of measurement authority to indicate the quality of results. Stability of the pressure measuring instruments over the years is one of the important parameters in defining the quality of re...
