The Software Engineering Institute's (SEI) Capability Maturity Model (CMM) gets a lot of publicity. Given that the institute is funded by the US Department of Defense to the tune of tens of millions of dollars each year [1], this should come as no surprise=97 the folks at the SEI are the official process mavens of the military, and have the resources to spread the word about what they do. But, ...

Coordinate Measuring Machines (CMMs) are a strategic element in the manufacture of high-precision parts because their measurements of part geometries are used for quality control and feedback on the manufacturing process. Proper CMM operation requires accurate knowledge of the position of the CMM's part sensor. The performance of a CMM is limited by background vibration levels, environmental co...

Massive multiple-input multiple-output (MIMO) technology, which is characterized by the use of a large number antennas, key enabler for next-generation wireless communication and beyond. Despite its potential high performance, implementing massive MIMO system presents numerous technical challenges, including hardware complexity, cost, power consumption that result from antennas associated front...

The Coordinate Measuring Machines (CMMs) are widely used for the three-dimensional measurements of workpieces. For solving the limits and the drawbacks of the traditional CMMs, we have started developing nano-CMM that measures three dimensional parts in nanometer resolution. In this article, we evaluate the repeatability and the straightness of stages of nano-CMM.

New sensor technologies play an important role in quality evaluation of Chinese materia medica (CMM) and include near-infrared spectroscopy, chemical imaging, electronic nose and electronic tongue. This review on quality evaluation of CMM and the application of the new sensors in this assessment is based on studies from 2010 to 2015, with prospects and opportunities for future research.

The paper presents the results of tests carried out to validate a new method for evaluating uncertainty coordinate measurements categorised as Sensitivity Analysis (SA). This concerns measuring dimensions and geometrical deviations. Measurement is evaluated on basis information given in Maximum Permissible Error (MPE) formula Coordinate Measuring Machine (CMM). models express measured character...

Some recent studies have shown an association between sleep disordered breathing (SDB) and cancer mortality and incidence but no study has focused on a specific type of cancer. The objective of this study was to analyse the relationship between the severity of SDB and factors related to cutaneous malignant melanoma (CMM) aggressiveness. We performed a multicentre observational study in 82 conse...

The aim of management information systems is to satisfy the information need managers have to successfully accomplish their tasks. The quality of management decisions is highly dependent on the information they are based on. A structured conception of these systems is a crucial task that has to precede their implementation and monitoring. Several conceptual modeling methods (CMM) for business i...

Glutathione Stransferases (GSTs) are a group of enzymes that act to detoxify reactive oxygen species resulting from oxidative stress processes and melanin production. GSTP1 is a polymorphic gene encoding variant proteins involved in metabolism. The role of the rs1695*A/G GSTP1 Ile105Val polymorphism in cutaneous malignant melanoma (CMM) susceptibility remains controversial. Two recent metaanaly...

BACKGROUND The aim of this study was to investigate the feasibility of using serum miR-221 as a noninvasive prognostic biomarker for cutaneous malignant melanoma (CMM). MATERIAL/METHODS We measured the expression levels of miR-221 in serum samples from 72 CMM patients and 54 healthy controls by real-time quantitative polymerase chain reaction (RT-PCR). The overall survival (OS) and disease-fr...
