The Hotelling's  control chart, is the most widely used multivariate procedure for monitoring  two or more related quality characteristics, but it’s power lacks the desired performance in detecting small to moderate shifts. Recently, the variable sampling intervals (VSI) control scheme in which the length of successive sampling intervals is determined upon the preceding values has been proved t...

Effective testing can develop quality software with higher productivity at a lower cost. As the software is modified and new test cases are added to the test suite, the size of the test suite grows and the cost of testing is also increases. In order to reduce the cost of testing researcher have investigated the use of test suite reduction technique. Redundancy in test suite increases the execut...

BACKGROUND Studies have demonstrated that self-testing for human immunodeficiency virus (HIV) is highly acceptable among individuals and could allow cost savings, compared with provider-delivered HIV testing and counseling (PHTC), although the longer-term population-level effects are uncertain. We evaluated the cost-effectiveness of introducing self-testing in 2015 over a 20-year time frame in ...

Testing for latent tuberculosis infection (LTBI) in HIV-infected persons in low tuberculosis (TB) incidence areas is often recommended. Using contemporary, clinical data, we report the yield and cost-effectiveness of testing all HIV attendees, two current UK strategies and no LTBI testing. Economic modelling was performed utilising 10-year follow up data from a large HIV clinical cohort. Outcom...

In this paper, we present the estimation of Poisson intensity based on hypothesis testing in the wavelet domain for any dimensional data. The testing framework for wavelet-based Poisson intensity estimation was first introduced by Kolaczyk, where a thresholding estimator, which realizes the hypothesis testing, is derived for Haar wavelet coefficients. Here we propose for the same wavelet a new ...

PURPOSE To identify factors that determine patients' intentions to use point-of-care medical devices, ie, portable coagulometer devices for self-testing of the international normalized ratio (INR) required for ongoing monitoring of blood-coagulation intensity among patients on long-term oral anticoagulation therapy with vitamin K antagonists, eg, warfarin. METHODS A cross-sectional study that...

OBJECTIVES Human papillomavirus (HPV) testing is not widely used for triage of equivocal Pap smears or primary screening in Québec, Canada. Our objective was to evaluate the cost-effectiveness of cervical cancer screening strategies utilizing HPV testing. METHODS We used a lifetime Markov model to estimate costs, quality of life, and survival associated with the following strategies: 1) cytol...

Software test and analysis are essential techniques for producing dependable software. While one cannot “test quality into” a badly constructed software product, neither can one build quality into a product without test and analysis. Achieving adequate quality through testing is often a major cost in software development, as well as a major factor in product cycle time. Failing to obtain adequa...

Testing products in a cost-efficient way remains an attractive topic for Model-Based Testing (MBT) of product lines in both academia and industry, which can be addressed by employing systematic and automated approaches based on models (such as feature models and UML models). Cost-effective testing products can be divided into three main problems, i.e., test selection, test generation, and test ...

Composite materials offer an appealing combination of low weight and high strength that is especially sought after in high-performance applications. The use of composite materials has and is continuing to increase, and the use of the material has been shown to provide substantial weight savings in for example aircraft design. With an increased use of composite materials follows an increased dem...
