Detecting product quality defects through image recognition technology is one of the key technologies of intelligent manufacturing, and also an important step for enterprises to construct smart factory. In the capsulation step of the semiconductor enterprise, the internal wire bonding of the chip is easily to receive the interference and to produce the defects. Companies need to pick out defective chips to avoid them going to the market. Traditional way is to use artificial vision visual inspection, which may lead to low efficiency and high labor cost. This study intends to use machine vision detection method based on image processing technology to identify the defect of the chip and to replace the workers artificial detection work. This paper proposes two algorithms to solve such above problems. The template matching algorithm (TMA) is to determine whether the chip is defective mainly based on the standard template. The neighborhood comparison algorithm (NCA) mainly calculates similarity of the neighbor chips to judge the target chip's defects. The algorithm is implemented by Halcon software. A German semiconductor company has provided enough samples to support our research. The experimental results show that the two algorithms are effective in defect detection of specific products. The advantage of the TMA lies in its processing speed, but the applicability and accuracy of NCA is more excellent. The algorithm proposed in this study can be used for enterprise by being integrated into the actual detection process.

The online routing problem of two vehicles to an emergency scene is considered. In grid transportation network, some of the edges may be suddenly blocked and the blockage will not be observed until reaching an endpoint of the blocked edge. The goal is to minimize the arrival time of the first vehicle with at most k blockages. An online strategy named Row-first and Line-first is presented and the competitive ratio is analyzed, and the ratio is proved to be tight. The optimization of the online strategy in some situations is also proved.

With the slowing growth of the telecommunication market and the intense competition for existing customers, Customer Churn Management has become a crucial task for all mobile network operators. Recommendation models based on customer behaviors are widely used by operators to provide diverse telecom tariff packages for suitable people and thus improve customer satisfaction. To address the low precision rate and data granularity of prior studies, this study combined rotation forest (ROF) and LightGBM and construct a hybrid algorithm (ROF-LGB). Grid search method was used in parameter tuning, and ten-fold cross-validation method was used to prevent overfitting. Using mobile data generated by operators, ROF-LGB method was tested and compared with other five traditional machine learning methods. The results showed that ROF-LGB method achieved better performance with better precision rate and execution efficiency in telecom tariff package recommendation. © 2019 Association for Computing Machinery.

In this paper, we examine the knowledge transfer process on community networks by analyzing the average knowledge level as a function of the agent's absorptive capacity. It is found that the average knowledge level decreases with the increment of inner-community links and the decreases of inter-community links when we keep the total links (including inner-community and inter-community links) constant. It is also shown that as for inner-community (inter-community) links unvaried, the increment of inter-community (inner-community) will promote average knowledge level.

Recently, the platform economy allows enterprises to collaborate with business partners and provide additional channels for various parties. E-commerce platforms have become integral channels for connecting suppliers with consumers. In the platform economy, agency selling and reselling are two predominant sales models that often coexist for the same product types, resulting in a competitive relationship. This study analyzes transaction data for 30,000 Stock Keeping Units (SKUs) provided by the Chinese e-commerce platforms over one month. We employ three models to compare the sales quantity and profits of manufacturers and online platforms and to identify the most efficient mode for stakeholders based on the model establishment and empirical evidence. Our findings suggest that apart from the existing channel to provide products to customers, manufacturers enter the platform which will increase the profit of platform operators. On the other hand, platform operators may also affect the profit of the manufacturers. © 2023 IEEE.

Neuropathic pain has serious impacts on the quality of people's life. Diosgenin extracted from yams has shown significant potential in the treatment of nervous system diseases. To investigate the potential mechanism of diosgenin fighting against neuropathic pain, we established a chronic compression injury (CCI) model. The pain-related behaviors were determined by Von Frey, hot plate, and sciatic nerve index test. As a result, diosgenin significantly lowered the pain threshold, improved the sciatic nerve index, and decreased the damage of sciatic nerve structure in CCI model mice. It increased the protein levels of LC3-II and Beclin-1, the number of the lysosomes, decreased the protein level of P62 and the number of the autophagosomes, and therefore activated autophagy. Diosgenin also inhibited the proliferation of microglia cells and the translocation of NF-κB p65, while promoting promoted M2 polarization of microglia cells. Autophagy inhibitor like chloroquine inhibited the M2 polarization of microglia cells, and reversed the therapeutic effect of diosgenin. All in all, diosgenin alleviated neuropathic pain in CCI mice based on the enhancement of autophagy and the promotion of M2 polarization.
