On the Accuracy of Time Measurements in Virtual Machines

2013 IEEE Sixth International Conference on Cloud Computing, 2013
While cloud computing permits access to a large pool of experimental infrastructure, the most common form - virtual machines - has been shown to exhibit substantial deficits with respect to the accuracy of time measurements. In our ongoing work, we provide a detailed analysis of these deficits based on various machine configurations.

Improvement of the machining accuracy of milling robots

Production Engineering, 2014
This paper presents an approach to improve the machining accuracy of milling robots. The low static stiffness of industrial robots leads to huge deflections of the tool. Hence, robotic milling can only be applied for tasks with low accuracy requirements and minor cutting forces (e.g., deburring or trimming).

Machining accuracy detection of PCB hole by X-ray micro-CT.

Micron, 2020
Over the past few years, non-destructive testing plays an increasingly important role in the accuracy detection of PCB manufacturing. Due to the complexity of PCB materials and the development of PCB towards high density.

Sensitivity analysis of machining accuracy reliability considering partial correlation of geometric errors for Horizontal Machining Center

, 2020
With the increase in working time, the geometric errors of a Horizontal Machining Center (HMC) will also increase under load, temperature, and wear conditions, decreasing the machining accuracy.

Reliability Assessment of Machining Accuracy on Support Vector Machine

2008
In order to establish the reliability model of limited samples, a kind of support vector machine (SVM) tools LSSVM.M is used to process reliability assessment data. The choice of parameters is the key factor to affect the forecasting accuracy. To improve the accuracy, a method of advanced parameters choice is proposed, which consists of two steps ...

Principal Components and the Accuracy of Machine Learning

1992
Induction algorithms could be positioned somewhere between witchcraft and science since extracting rules (the essence of data semantics) from an incomplete set of examples is a devil’s task. On the other hand there always has been some romanticism in the interpretation of eigenvalues.

Influence of different featured tools on machining accuracy in electrochemical milling

Proceedings of the Institution of mechanical engineers. Part B, journal of engineering manufacture, 2019
Drawbacks of electrochemical machining can be conquered to a large extent with the introduction of electrochemical milling technique. In this method, a simple shaped tool follows a predetermined tool path and material gets removed atom-by-atom from anode
