Conventional methods for assessing the quality of components mass produced using injection molding are expensive and time-consuming or involve imprecise statistical process control parameters. A suitable alternative would be to employ machine learning to classify the quality of parts by using quality indices and quality grading. In this study, we used a multilayer perceptron (MLP) neural network along with a few quality indices to accurately predict the quality of “qualified” and “unqualified” geometric shapes of a finished product. These quality indices, which exhibited a strong correlation with part quality, were extracted from pressure curves and input into the MLP model for learning and prediction. By filtering outliers from the input data and converting the measured quality into quality grades used as output data, we increased the prediction accuracy of the MLP model and classified the quality of finished parts into various quality levels. The MLP model may misjudge datapoints in the “to-be-confirmed” area, which is located between the “qualified” and “unqualified” areas. We classified the “to-be-confirmed” area, and only the quality of products in this area were evaluated further, which reduced the cost of quality control considerably. An integrated circuit tray was manufactured to experimentally demonstrate the feasibility of the proposed method.

Quality Grading

The concepts of market segmentation, grading and sorting are outlined and criteria are proposed. The application of these criteria to the sorting of cucumbers and tomatoes did not achieve effective market segmentation, and quality grading was only partially achieved.

Abstract In tests with bias ply, belted bias, and radial commercial passenger car tires it was found that the rate of wear does not change as the tires are worn. It was also shown in a test which there were dry and wet periods that the same tires wore at a faster rate in the wet than in the dry. This observation was reinforced when a comparison of two tests run with duplicate sets of tires in January and June on the same course gave greatly different results; the greater rate of wear occurring in January when the course was continuously wet. Finally an explanation for the observation that tires wear faster on wet pavements has been proposed. The tire is more deformed passing through the contact patch on a wet surface than on a dry. In addition, the water, acting as a lubricant, reduces resistance to motion between surfaces of the cut rubber or the surface of the cutting asperity and the rubber.

Human Health Effects

Today, there are many studies about the problems that may be faced in the context of World Water Day. In this chapter, the structure, pollution, quality grading, and human health effects of water; possible pollution prevention measures; and water safety are discussed. It is expected that the world population, which is about 7 billion currently, will rise to 9 billion by 2050. Water consumption is expected to increase at a higher rate, which is a major problem for the environment. By 2025, it has been estimated that two-thirds of the world's population will deal with water shortage. The world is not as rich in water as once thought and, hence, is at high risk for water shortage. For these reasons, we must all fulfill our responsibility to leave a habitable world to future generations.
