Achieving a high quality product corresponding consumer requirements involves organizing and supporting the production process with a suitable and flexible logistics process. As the process / production flow is better organized, divided into subdomains (production, maintenance, quality), each with clearly defined indicators and responsibilities, the more the process will be more stable, easier ...

Uncertainty quantification is an important approach to modeling in the presence of limited information about uncertain quantities. As a result recent years have witnessed a burgeoning body of work in this field. The present paper gives some background, highlights some recent work, and presents some problems and challenges.

Field-grade atomic clocks capable of primary standard performance in compact physics packages would be of significant value in applications ranging from network synchronization to inertial navigation. A coherent-population-trapping clock featuring laser-cooled 87Rb atoms and pulsed Ramsey interrogation is a strong candidate for this technology if the frequency biases can be minimized and contro...

Liver masses in cirrhosis are increasingly being recognized with the use of new imaging modalities. The majority of these lesions are detected by ultrasound, enhanced CT and MRI. The most likely diagnosis of a solid liver lesion in a cirrhotic liver is hepatocellular carcinoma, followed by high grade or low grade dysplastic nodule, and cholangiocarcinoma. Lymphoma and liver metastasis are extre...

Substantial uncertainty exists about the impact of school quality on the black-white achievement gap. Sizeable achievement differences by race as of 1 grade and test error complicate any investigation of this issue, because average test score growth rates may differ across the distribution depending upon the test instrument, curriculum, and other factors. Texas administrative data show that the...

BACKGROUND Unsatisfactory colposcopy, where the cells of interest are not visible in women with a positive cervical screening test, is a common area of clinical uncertainty due to the lack of clear evidence and guidance. Colposcopists' opinions and experiences are likely to have a significant influence on service provision and the development of national policy. The aim of this study was to ana...

BackgroundNon-operative management (NOM) is accepted treatment of splenic injury, but this may fail leading to splenectomy. Splenic artery embolization (SAE) improve rate salvage. The purpose determine the cost-utility addition SAE for high-grade injuries.MethodsA analysis was developed compared NOM in patients with blunt injury. Sensitivity completed account uncertainty. Utility outcome qualit...
