This paper presents a taxonomy of methods for online performance verification of three-axes Coordinates Measuring Machines (CMMs). The attention is focused on analytical redundancy methods, which are based on the use of mathematical models to describe physical relationships between measured quantities. A general framework for the application of the analytical redundancy methods is presented. A ...

AURA (Advanced Uncertain Reasoning Architecture) is a generic family of techniques and implementations intended for high-speed approximate search and match operations on large unstructured datasets. This paper continues the AURA II (Advanced Uncertain Reasoning Architecture) project’s research into distributed binary Correlation Matrix Memory (CMM) based upon the PRESENCE (PaRallEl Structured N...

Computerized maintenance management systems (CMMSs) contain valuable data on the operations in an organization. A large part of these consists unstructured, written texts contained failure notifications which are generated each time unexpected occurs, enriched with structured metadata consisting a number labels that allow to categorize failures, such as type failure, its cause or corrective act...

PURPOSE Choroidal malignant melanomas (CMMs) are the most common primary intraocular tumors in adult humans. Although radiotherapy is commonly used to treat the melanomas, the therapeutic effects are unpredictable. The purpose of this study was to search for a gene(s) that can predict the success of radiotherapy for CMMs. METHODS The cell lines 92-1, OCM-1, and OMM-1 were established from pat...

BACKGROUND An increasing number of model-based studies that evaluate the cost effectiveness of treatments for depression are being published. These studies have different characteristics and use different simulation methods. OBJECTIVE We aimed to systematically review model-based studies evaluating the cost effectiveness of treatments for depression and examine which modelling technique is mo...

Nowadays, the use of freeform surfaces in various functional applications has become more widespread. Multi-sensor coordinate measuring machines (CMMs) are becoming popular and are produced by many CMM manufacturers since their measurement ability can be significantly improved with the help of different kinds of sensors. Moreover, the measurement accuracy after data fusion for multiple sensors ...

Services oriented grids will be more prominent among other kinds of grids in the present distributed environments. With the advent of online government services the governmental grids will come up in huge numbers. Apart from common security issues as in other grids, the authorization in service oriented grids faces certain shortcomings and needs to be looked upon differently. The CMMS model pre...

Ever since the introduction of coordinate measuring machines (CMMs), their measuring accuracy has been studied. Much research work has focused on the accuracy characteristics of the measuring system, e.g. the static errors and dynamic errors of the machines. However, the additional error sources can be introduced when a measuring coordinate system is set up. This paper describes how to analyse ...

The current series of international standards for performance evaluation of Coordinate Measuring Machines (CMMs), ISO 10360, outline tests that allow manufacturers (OEMs) to publish specifications in such a way that it is more difficult for the non-expert CMM user to compare different brands of machines. The intent is to improve competitive advantage by having a very attractive, yet many times ...
