In this study, feature extraction from a transient response of a semiconductor gas sensor is investigated. For the sensor response given as the step response of the fi rstorder lag system, the sensor output can be approximated as a sum of exponentials by Prony’s method. The model parameters can be estimated as the time constant and the gain, which are inherent parameters for each gas. The param...

We discuss a method aimed at reducing the risk that spurious results are published. Researchers send their datasets to an independent third party who randomly generates training and testing samples. Researchers perform their analysis on the former and once the paper is accepted for publication the method is applied to the latter and it is those results that are published. Simulations indicate t...

A common method for drawing directed graphs is, as a rst step, to partition the vertices into a set of k levels and then, as a second step, to permute the vertices within the levels such that the number of crossings is minimized. We suggest an alternative method for the second step, namely, removing the minimal number of edges such that the resulting graph is k-level planar. For the nal diagram...

As profit of steel enterprises is getting smaller and comparison harder, in manufacturing industry quality inspection control have become main measures for over the difficulties. In sequential process, failure occurred preceding process make final worse. Detecting factor which affects to necessary stable efficient. Existing studies improve surface small bars assume that these been identified fo...

Purpose Robotic process automation (RPA) has recently emerged as a technology focusing on the of repetitive, frequent, voluminous and rule-based tasks. Despite few practical examples that document successful RPA deployments in organizations, evidence its economic benefits been mostly anecdotal. The purpose this paper is to present step-by-step method investment appraisal business case demonstra...
