With the development of Information Technology (IT) and Software-Defined Networking (SDN), Communications Service Providers (CSPs) can collect much information from telecommunication circuits. However, some of the existing circuit measurement has not been used well. For CSPs, it is important to find more efficient ways of utilizing the circuit measurement, e.g., delay, jitter, packet loss, and speed-test results for customer satisfaction. One of the most popular ways is to use speed-test tools (such as Speedtest online) to measure the service rate of the application layer. However, it is difficult to justify whether the telecommunication circuit is normal or not. For example, when the speed-test result of a specific circuit is 90 Mbps, the physical line rate may be 100Mbps. To address the above issues, we first investigate the measurement and management mechanisms of the existing telecommunications networks, including the core components and protocols. In this paper, we leverage artificial intelligence (AI) technologies to predict whether customers complain or not. We evaluate the proposed AI model by using the real data from telecommunication circuits and analyze the key performance metrics.
随着信息技术(IT)和软件定义网络(SDN)的发展,通信服务提供商(csp)可以从通信电路中收集到大量的信息。但是,现有的一些电路测量方法并没有得到很好的应用。对于csp来说,重要的是找到更有效的方法来利用电路测量,例如延迟、抖动、数据包丢失和客户满意度的速度测试结果。最流行的方法之一是使用速度测试工具(如Speedtest online)来测量应用层的服务速率。然而,很难判断电信电路是否正常。例如,某个电路的速度测试结果为90mbps,则物理线路速率可能为100Mbps。为了解决上述问题,我们首先研究了现有电信网络的测量和管理机制,包括核心组件和协议。在本文中,我们利用人工智能(AI)技术来预测客户是否会投诉。我们通过使用来自电信电路的真实数据来评估所提出的人工智能模型,并分析关键性能指标。

This paper proposes an analysis of subsampled image size for detection and identification of brake pad contours by using deep learning for the automatic detection systems. In brake pad manufacture, some problems may occur such as expansion, missing corners at the edges so that the edges of the brake pad need to obtain before checking missing corners. The size of subsampled image for training and testing for machine learning is very significant factor for optimized and efficient feature extraction. The size of subsampled image has great impact on detection and identification for feature extraction determines the accuracy of prediction of deep learning. The images are evaluated through loss function in order to observe the training process of the models. The experimental results show the method to determine subsampled image size to have better accuracy.

The foveal avascular zone (FAZ) is a region on a retinal image where blood vessels distribute sparsely. It helps identify diabetic retinopathy. In this study, we investigate the optical coherence tomography angiography (OCTA) to analyze the extent of the FAZ more precisely. Moreover, a learning-based denoising architecture is applied to well distinguish the vascular vessel and the noise. With these techniques, the FAZ in an OCTA image can be well extracted and its area can be estimated accurately.

This study aims to prove the influence of wetness on the mechanical characteristic of carbon fiber–reinforced plastic (CFRP). There is no suitable method for using lubrication fluids in the composite industry. There is a significant impact on CFRP machining capabilities by the geometry of the cutting tool and cryogenic liquid cooling. This paper selects the optimal parametric combinations of the carbon fiber reinforced plastic drilling process by using Taguchi optimization technique base on grey relation analysis (GRA) technique (TGRA). The parameters of the drilling process such as the helical angle of the blade, the coolant gas, and the feed rate were found by observing multi-responses output such as surface roughness and diameter of the drill hole. The following parameters resulted in a larger value of grey relational grade (GRG) to reduce the surface roughness and the error deviation of the diameter dimension: the speed of the spindle motor was 6100 rpm, the feed rate was 1006 mm/min, the helical angle of the cutting blade was triple, the coolant gas was CO2-N2 mixture. Finally, an analysis of variance (ANOVA) is used to analyze the effect of each parameter process in the estimation of GRG. The results showed that the coolant gas had an outstanding effect on the surface roughness and error deviation of the diameter dimension.
本研究旨在证明湿度对碳纤维增强塑料(CFRP)力学特性的影响。在复合材料工业中没有合适的润滑液使用方法。刀具的几何形状和低温液体冷却对碳纤维布的加工能力有重大影响。采用基于灰色关联分析(GRA)技术的田口优化技术(Taguchi optimization technique, TGRA)选择碳纤维增强塑料钻孔工艺的最优参数组合。通过观察钻孔表面粗糙度和钻孔直径等多响应输出,得到了叶片螺旋角、冷却气体和进给速率等钻孔过程参数。当主轴电机转速为6100 rpm,进给速度为1006 mm/min,切削叶片螺旋角为3倍,冷却气体为CO2-N2混合气时,采用较大的灰色关联度(GRG)值来减小表面粗糙度和直径尺寸的误差偏差。最后,利用方差分析(ANOVA)分析了各参数过程对GRG估计的影响。结果表明,冷却气体对表面粗糙度和直径尺寸误差偏差有显著影响。

The change of gray contract reflects the morphology of the sample in an SEM image. Quantifying the gray contract is important for flex manipulation and the vertical measurement with SEM. Traditional methods focus on the 2D plane, thus are limited by the complex experimental system and lack of timeliness. We design and fabricate a new microprobe that measures the vertical distance in SEM simply by processing images of the semi-transparent pinhole at the tip of the microprobe. First, we propose the model of the microprobe by watching the morphology of the AFM probe. Second, we obtain the structure parameters of the microprobe by analysis and simulation. Finally, we fabricate the microprobe that combines 3D printing and FIB precision manufacturing. The result provides the foundation for grayscale characterization experiments in the SEM.

Thus, the establishment of an index system for evaluating the capacity of water resources becomes important. In this study, a comprehensive analysis of relevant research results was performed to compile indexes for evaluating the capacity of water resources. The Delphi method was adopted to acquire expert opinions on the adequacy of various evaluation indexes. The interquartile range was used to assess the adequacy indexes. The study results serve as a reference for the evaluation of urban water resources.

The applications of five-axis machining have been used widely recently. Owing to the expensive cost of machine tools, how to detect the collision in real time has become a critical issue. Indeed, in order to ensure that G-codes will not result in the collision, the developers may use some tools before the stage to process the five-axis machine tool on off line. Moreover, to reduce long execution time on off line, we propose a parallel method to remedy it in this paper. The objective of the proposed approach aims at improving the performance to detect collision in parallel by utilizing the functions of a GPU (Graphics Processing Unit).We address the issue above by inducing six separating axis in plan and 11 separating axis in non-plan for two triangle meshes. Then we propose a parallel approach by implementing a CUDA ( Compute Unified Device Architecture ) program based on a GPU. Finally, with our domain knowledge and experiences, we attempt to optimize the proposed work with loop unrolling and prefetching techniques to improve performance.. The result shows that our work is very efficiently by using the two techniques.
近年来,五轴加工得到了广泛的应用。由于机床的昂贵成本,如何实时检测碰撞已成为一个关键问题。的确,为了保证g码不会造成碰撞,开发人员可能会在阶段前使用一些工具对五轴机床进行离线加工。此外,为了减少离线执行时间长,本文提出了一种并行方法来弥补这一缺陷。该方法旨在利用图形处理单元(GPU)的功能来提高并行碰撞检测的性能。我们通过在两个三角形网格中引入6个平面分离轴和11个非平面分离轴来解决上述问题。然后,我们提出了一种基于GPU实现CUDA(计算统一设备架构)程序的并行方法。最后,根据我们的领域知识和经验,我们尝试使用循环展开和预取技术来优化所提出的工作,以提高性能。结果表明,使用这两种技术,我们的工作效率很高。

This study investigates the effects of the vent-area on bubble-microstructure and shrinkage variation of gas-assisted foam-injection molding (GAFIM). The molding material is polystyrene (PS), and the gas foaming agent is nitrogen (N2). This study carried out the injection experiment with and without GAFIM to observe the molding characteristics of gas-filling pressure variation. In addition, the integration of vent-area volumes and cavity pressure measurement was developed to achieve foam growth and microstructure inside the sample to observe the effect of with and without vent-area on shrinkage variation and correlated pressure distribution near gate position during the filling process. The experimental results revealed that with the vent-area, the sample dimension shrinkage was relatively improved and the sample weight was reduced. On the other hand, the bubble-distribution increased with the changes in the volume of the vent-area and gas-filling pressure as the foam growth space increased.

We proposed a design and sacrificial-based fabrication process of capacitive pressure sensor with SiGe as a structural layer and movable electrode. Simulated results showed that its sensitivity was around 15fF/bar in a full-scale span from 30 to 110kPa. The initial stress for the used materials was also discussed in this study.

It is a common task when employing the microservices architecture to integrate a number of loosely coupled entities that communicate with each other resulting in service requests that disseminate through a number of service endpoints. As the number of service endpoints increases, identifying the path to which a service request passes through the network becomes a time consuming and challenging task. In addition, as part of service requests, personal data may be shared across a number of service providers without end-users’ knowledge. Hence, tracing service requests and the extent to which data is flowing from one service endpoint to another becomes inevitable. In this paper, we introduce a distributed tracing Privacy Risk Detection (dtPRD) framework for identifying potential privacy and security risks associated with the dissemination of data through the path a service request undergoes. Identifying any risks associated with data sharing across a service path or plan can help in classifying service endpoints that are vulnerable or have the potential of exposing data without the end user’s knowledge. Throughout the paper, we present experimental and validation results of our proposed approach which show the effectiveness and usefulness of the dtPRD framework.
当使用微服务体系结构集成许多松散耦合的实体时,这是一个常见的任务,这些实体相互通信,从而产生通过许多服务端点传播的服务请求。随着服务端点数量的增加,确定服务请求通过网络的路径成为一项耗时且具有挑战性的任务。此外,作为服务请求的一部分,个人数据可能在最终用户不知情的情况下在多个服务提供商之间共享。因此,跟踪服务请求以及数据从一个服务端点流向另一个服务端点的程度变得不可避免。在本文中,我们引入了一个分布式跟踪隐私风险检测(dtPRD)框架,用于识别与通过服务请求经历的路径传播的数据相关的潜在隐私和安全风险。识别与跨服务路径或计划的数据共享相关的任何风险,有助于对易受攻击或可能在最终用户不知情的情况下暴露数据的服务端点进行分类。在整篇论文中,我们提出了我们提出的方法的实验和验证结果,这些结果显示了dtPRD框架的有效性和实用性。
