The accurate measurement of gas flow is directly related to the economic benefits and social interests of gas enterprises. Moreover, as a kind of time-series data, there is a serious imbalance in the distribution of positive and negative samples in the data, which leads to low accuracy and difficulty in detecting gas anomaly data. To address these problems, a cost-sensitive hybrid network model is proposed in this paper. The model combines the stronger local feature learning ability of CNN network and the better sequence feature learning ability of GrU network, and then introduces a cost-sensitive loss function to solve the problem of inaccurate classification accuracy due to skewed data distribution. The experimental results show that using this model can find the outliers in the measurement data more accurately, which has some reference significance for the accurate measurement of traffic. © VdE VErLAG GMBH ∙ Berlin ∙ Offenbach.

Epoxy Molding Compound (EMC) bleed consists of a transparent layer of resin which mainly could occur during molding injection at material packing stage. resin bleeds on exposed pad of a Surface Mount device (SMd) can significantly impact the solderability performances of the package, causing failure of the product. de-flashing process after molding is generally performed to eliminate the resin bleed. However, de-flashing can be performed on post-plated leadframes without critical drawback, while it is not recommended on pre-plated leadframes due to the high risk of damaging the finishing surface. In this study, an alternative approach aimed to reduce or eliminate molding compound bleed by optimizing the inorganic part of the molding compound formulation is presented. Besides the quality improvement, the presented approach provides an economical advantage since, by tuning the properties of the filler inside the EMC, it is possible to eliminate the de-flashing process from the assembly flow of a package and consequently reduce the manufacturing cost.

Precision Education (PE) is an approach that emphasizes the use of various forms of technology to personalize students’ educational opportunities according to their unique requirements. In order to facilitate effective learning that is suited to the needs of each individual, it is necessary to have complete information about the learning process. PE describes a personalized approach to classroom instruction. We propose dignified reinforcement Learning (drL) which includes all the essential elements required for PE, in order to determine the impact of developing multimodal innovations on individualized learning. The system aims to address issues with the standard model of education analysis, such as insufficient internal validity, predictive validity, timeliness, comparability, and understandability, in order to provide more precise instruction. Networking sites, the digital classroom, the intelligent agent, and the panel are the four fundamental aspects of an rL-based technology. Through model-based rL, the head attribute of the continuous educational environment gathers and processes a multimodal flow of student records from the various modules to create laws of appropriate behaviors that optimize the long-term benefits for both the individual and the computer. To demonstrate the usefulness of the proposed model, experimental evidence was presented using a subset of multimodal data. Practical and theoretical implications for future digital learning approaches and investigations may be drawn from rL systems. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Coherent diffraction Imaging (CdI) is a promising method for the metrology of lithographic structures due its low cost, ease of implementation, and scalability. CdI can be realized in different ways, but the core process involves illuminating the sample with coherent light, recording the diffracted intensity distribution, and computationally recovering the phase to reconstruct the complex amplitude of the sample. One of the primary challenges in semiconductor metrology is high resolution inspection for lithographic patterns. Although the patterns can be relatively complex, periodic structures are found in many layers of modern devices. Given the traction gained by hybrid bonding for wafer-to-wafer (W2W) or chip-to-wafer (C2W) interconnects, their metrology is becoming important. It is interesting to study and research phase retrieval methods that can potentially be applied to reconstruct the topography of the Cu pads structures that are used for the electrical connections in such scenario. This paper presents a study of phase retrieval algorithms applied to reconstruct the profile of the dishing/protrusions present on each Cu pillar of the array. In particular, we explore a sample model featuring a Cu pad array where the single pillars have a bowl-shaped topography and we investigate, by means of simulations, the accuracy that we can achieve with this approach in the measurement of the depth and shape of the concavity of the surface of the pillars. © 2025 SPIE.

In this paper, three types of ultra-thin interfacial oxide layers including GeO 2 , Al 2 O 3 , and SiO 2 , are designed to inserted into the interface of MoTe 2 /Ge heterojunction to investigate its impact on the photoelectric performance. The device with GeO 2 interfacial layer exhibits the maximum responsivity and detectivity as well as the relatively large rectification ratio, reaching values of 1.38 A/W, $1.32\times 10^r$ Jones, and 140, respectively. For the device with Al 2 O 3 interfacial layer, the maximum rectification ratio and the relatively high detectivity are achieved, reaching values of 807 and $1.56\times 10^r$ Jones, respectively. While for the MoTe 2 /Ge heterojunction with SiO 2 interfacial layer, which shows an ideality factor of 2.14 and the lowest rectification ratio together with the detectivity. These results indicate that both the interface quality and bandgap of ultrathin interfacial layer would be crucial for the photoelectronic performance of MoTe 2 /Ge heterojunction.

We have recently proposed a theoretical model for the mechanism of heat production in the mitochondrial respiratory chain, derived from the overpotential of electrochemical reactions in enzyme catalysis. A key feature of this overpotential-derived thermogenesis model is that the distribution of energy consumption between thermogenesis and adenosine triphosphate synthesis changes depending on the reaction rate. To verify that similar energy partitioning occurs in other metabolic reactions linked to the respiratory chain, we developed a system for the simultaneous measurement of thermogenesis and respiration rate in yeast cells. We correlated the amount of thermogenesis with the respiration rate, finding that most thermogenesis in yeast cells is derived from fermentation, which is connected to the respiration rate. By investigating the relationship between fermentative heat production and respiration rate, we discovered that the energy partitioning between heat production and substance synthesis exists and changes depending on the respiration rate. This strongly suggests the existence of electrochemical overpotential-derived thermogenesis in metabolic processes. ©2024 The author(s)

This study examines how flow velocity affects the current response due to erosion damage in a polyurethane, CNT, and rGO nanocomposite. Increased nano-filler content improved conductivity, transitioning the material from an insulator to a conductor. Erosion tests in a NaCl solution with sand showed higher flow velocities caused more surface damage. The current slope closely correlated with flow velocity. An ensemble model using current density slope data, including SVr, achieved high prediction accuracy with r2 values around 0.93 for both increasing and decreasing velocities. © 2024, The Authors.

Effect of microstructure and deformation on hardness distribution of wrought precipitation strengthened ni-based alloy after creep damage

引用

Zairyo/Journal of the Society of materials Science, Japan 2021年第3期70卷 258-263页

作者： Oinuma, Shun Takaku, reki Nakatani, Yujiro Takeyama, Masao Energy Systems R&D Center Toshiba Energy Systems & Solutions Corporation Tsurumi-ku Yokohama230-0045 Japan School of Materials and Chemical Technology Tokyo Institute of Technology Meguro-ku Tokyo152-8550 Japan

To establish the creep life assessment method for wrought precipitation strengthened Ni-based alloys, the factors which influence the hardness after creep damage were studied. Hardness measurements and microstructure quantification were done for crept specimen of γ'-Ni3Al precipitation strengthened alloy, TOS1X-2. Hardness increased with EBSd KAM and GAM value of measured location, suggesting the hardening by creep induced strains. Grain boundary and twin boundary were found to suppress the plastic deformation by hardness indent. Grains oriented to the stress axis showed high hardness, while grains oriented showed relatively low. This indicated the possible existence of orientation dependence of strain hardening, which might be explained by the number of slip systems likely to operate and the interactions of dislocation movement. The hardness seemed to be influenced by the γ' phase precipitation strengthening, plastic deformation resistance by grain boundary and strain hardening for each grain orientations. © 2020 The Society of materials Science, Japan.
