In this paper, we designed the image processing algorithm, which inspects fault of the parts using morphology operator. Input is images of parts and process image registration, and then calculates binary erosion and dilation operator. Compared dilation values and separate into good or error parts of the automobile. The performance of the designed image processing algorithm was verified by perfo...

Selection of an appropriate sample size is one of the most important aspects of any quality inspection. Th e right sample size enables making valid conclusions about the quality of the product with minimum necessary resources. Th e choice of sample size and the probability of Type II error (ß) are closely connected. Th e purpose of this paper is to examine how usage of a statistical power analy...

Testing, monitoring and evaluation of distributed systems at runtime is a difficult effort, due the dynamicity of the environment, the large amount of data exchanged between the nodes and the difficulty of reproduce an error for debugging. Application traffic analysis is a method to evaluate distributed systems, but the ability to analyze large amount of data is a challenge. This paper proposes...

Color and size are two important attributes for quality evaluation of most food and bioproducts. Many of the quality factors affecting oil palm and white powder starch are determined primarily by visual inspection. Such inspections determined market price and to a certain extent consumers' preferences. However, the inspection of oil palm and white powder starch is a very repetitive and tedious ...

the automation of visual inspection for printed labels, which are coated with rubber and curl, we have developed a camera-based portable experimental device of automatic inspection in this research. By experiments, we have verified that the experimental device surely detect the failures such as the stain, the patchiness, the spread, and the chip detected by using low dimensional feature vectors...

In practice the items received in a lot may contain defective items, and the screening process to eliminate the defective items may involve both a Type I and a Type II error. Due to the defective items and the inspection errors, shortages may sometimes occur. In this paper, we develop an economic order quantity model with imperfect quality items, inspection errors, shortage backordering, and sa...

This paper reports on current research to automate the task of ship hull inspection and search using autonomous underwater vehicles (AUVs). We describe an automated feature-based navigation (FBN) and mapping framework that provides the AUV with precise in-situ hull-relative localization. Our vision-based perception approach eliminates the need for having to deploy additional navigation infrastr...

API error-handling specifications are often not documented, necessitating automated specification mining. Automated mining of error-handling specifications is challenging for procedural languages such as C, which lack explicit exception-handling mechanisms. Due to the lack of explicit exception handling, error-handling code is often scattered across different procedures and files making it diff...
