Compared with hot embossing, microfluidic chips injection molding is higher efficiency process and more suitable for mass production, but the quality control for injection molding is much more complex. Experiments indicate that the incomplete replication of the micro-channel and the sink mark for microfluidic chips are the chief defects to the molding. Simulation and theoretical analysis show that the stagnant flow of the melt in micro-channel and the shrinkage difference of the chips in different directions are the main reasons for molding defect. A set of new methods that how to control process parameter, design mold, and select polymer material is proposed to reduce or avoid the defects.

This study describes and evaluates the methods developed for the module for the analysis of problems of the closed subject system of answers to questions for the Kazakh language. Question analysis is one of the most important components of a quality control system to obtain the information needed to determine what is being asked and how to answer it. Therefore, we propose new methods of problem analysis in two main problems, namely rule-based and hidden Markov model based on the integration of systematic classification, focus extraction and question classifiers, both of which depend on the relationship between words in the problem. uses the ratio. It also compares these solutions with basic models. This study also manually presents the gold standard aggregated and annotated data for further research in this area.

AbstractThe article specifies the dependence of defects occurring in the lamination process in the production of yachts. Despite great knowledge about their genesis, they cannot be completely eliminated. Authentic data obtained through cooperation with one of the Polish yacht shipyards during the years 2013–2017 were used for the analysis. To perform a simulation, the sample size was observed in 1450 samples, consisting of 6 models of yachts with closed and open deck. Finding the dependence of the occurrence of specific defects will allow for faster procedures and more effective quality control, which will contribute to lower costs. The use of new methods based on artificial intelligence related to Big Data allows for easier observation of dependencies in the complex structure of data from yacht production. The association rules were defined using the algorithm Apriori and define interdependent defects. A number of dependencies were found for the occurrence of production defects not obvious to technologists, but occurring with a high probability of coexistence. The presented research results may allow the planning process of production tasks to be improved.

Abstract. The World Optical Depth Research Calibration Center (WORCC) is a section within the World Radiation Center at Physikalisches-Meteorologisches Observatorium (PMOD/WRC), Davos, Switzerland, established after the recommendations of the World Meteorological Organization for calibration of aerosol optical depth (AOD)-related Sun photometers. WORCC is mandated to develop new methods for instrument calibration, to initiate homogenization activities among different AOD networks and to run a network (GAW-PFR) of Sun photometers. In this work we describe the calibration hierarchy and methods used under WORCC and the basic procedures, tests and processing techniques in order to ensure the quality assurance and quality control of the AOD-retrieved data.

ABSTRACTIn this methods paper, we describe a successful strategy to investigate locus-specific methylation by cloning-based bisulfite sequencing. We cover sample handling, DNA isolation, DNA quality control before bisulfite conversion, bisulfite conversion, DNA quality control after bisulfite conversion, in silico identification of CpG islands, methylation-independent bisulfite sequencing PCR (BSP) assay design, methylation-independent BSP, cloning strategy, sequencing and data analysis. Methods that are described nicely elsewhere will not be covered in detail. Instead, the focus will be on tips/tricks and new methods/strategies used in this protocol, including quality control assessment of the DNA before and after bisulfite conversion and a pooled cloning strategy to reduce time, costs and effort during this step. In addition we comment on dealing with bias and improving overall protocol efficiency.
