This paper presents an IoT-based automated settlement monitoring system that aims to meet the diverse requirements of applications and the increasing demand for settlement monitoring. The system consists of a perception subsystem, data transmission layer, IoT cloud platform, and application terminal. The differential pressure static level sensor transmits the sensor serial port raw data to the 4G DTU through the RS-485 bus interface. Then, the 4G DTU converts it into a 4G network and transmits the data to the IoT cloud platform via the MQTT protocol. The IoT cloud platform analyzes and processes the collected data to generate reports, visualize data to generate curves, and perform real-time anomaly identification on the data. Finally, it implements viewing of settlement monitoring data and curve changes, as well as monitoring status warnings at the application terminal. The practical engineering application results show that this system can provide effective safety monitoring and an early warning scheme for slope, tunnel, bridge, and building safety monitoring.

A broadband chip antenna designed for millimeter wave (mm W) can be used in fifth-generation (5G) frequency bands. The on-chip mmW antenna designed for the Ka-band utilizes standard Complementary Metal-Oxide-Semiconductor (CMOS) technology. In this design, the mmW antenna structure is formed by connecting the top layer (Metal6) and the bottom metal layer (Metal1) to reduce losses. Many architectures have been proposed for chip antennas to overcome the metal thickness during fabrication and improve the gain of chip antennas. Therefore, this paper proposes an on-chip antenna for the fifth-generation mobile communication millimeter-wave frequency band. Using high-frequency electromagnetic simulation software, the chip antenna exhibits a minimum return loss of -18dB at 31GHz and a peak gain of -7 dB. The measured reflection coefficient is below -10dB from 18.8 GHz to 32.5 GHz.
专为毫米波(mm W)设计的宽带芯片天线可用于第五代(5G)频段。为 Ka 波段设计的片上毫米波天线采用了标准互补金属氧化物半导体(CMOS)技术。在该设计中,毫米波天线结构是通过连接顶层(Metal6)和底层金属层(Metal1)来形成的,以减少损耗。为了克服制造过程中的金属厚度问题并提高芯片天线的增益,人们提出了许多芯片天线的架构。因此,本文提出了一种适用于第五代移动通信毫米波频段的片上天线。利用高频电磁仿真软件,该芯片天线在 31GHz 频率下的最小回波损耗为 -18dB,峰值增益为 -7dB。从 18.8 GHz 到 32.5 GHz,测量到的反射系数低于 -10dB。

Orthogonal time frequency space (OTFS) and non-orthogonal multiple access (NOMA) are pivotal for enhancing the transmission performance of vehicular communications. This paper delves into the downlink power allocation of a NOMA-OTFS system with a frequency domain linear equalizer (FD-LE), where a high-speed user in delay-Doppler domain and multiple low-speed time-frequency domain NOMA users coexist. Considering the fairness of NOMA users, we optimize the minimum rate of the low-speed users, constrained by the quality of service (QoS) of the high-speed user. To address this problem, we propose an iterative power allocation optimization (IP-AO) strategy and obtain an accurate optimal solution based on the auxiliary variables by transforming the original non-convex problem into a convex one. Moreover, we derive a closed-form solution for the optimal power allocation (OPA). Simulation results validate the superiority of our schemes over traditional power allocation methods in maximizing the minimum user rate in the NOMA-OTFS vehicular system.
正交时频空间(OTFS)和非正交多址(NOMA)对提高车载通信的传输性能至关重要。本文深入研究了带有频域线性均衡器(FD-LE)的 NOMA-OTFS 系统的下行链路功率分配,在该系统中,一个延迟多普勒域的高速用户和多个低速时频域 NOMA 用户共存。考虑到 NOMA 用户的公平性,我们优化了低速用户的最低速率,但受制于高速用户的服务质量(QoS)。为解决这一问题,我们提出了迭代功率分配优化(IP-AO)策略,并通过将原始非凸问题转化为凸问题,获得了基于辅助变量的精确最优解。此外,我们还推导出了最优功率分配 (OPA) 的闭式解。仿真结果验证了我们的方案在最大化 NOMA-OTFS 车辆系统的最小用户速率方面优于传统的功率分配方法。

The outcome of cancer patients mostly depends on the diagnosis process and the treatment strategies. Computer-aided diagnosis (CAD) methods have demonstrated the potential to handle accurate diagnostics using artificial intelligence techniques such as machine learning and deep learning. The nature of the data used in training the AI-based model determined the paradigm, often classified as supervised and unsupervised learning for scenarios with labeled and unlabeled data, respectively. Due to the cost of time and resources, most datasets are nowadays partially labeled and used for training. The weakly supervised learning approach enables the AI models to be trained with incompletely labeled, noisy, or imbalanced data. In recent years, multiple instance learning (MIL) has emerged as a promising weakly supervised learning approach in many fields, including cancer diagnosis. Unlike traditional supervised learning methods, MIL allows the classification of groups of instances, known as bags, where only the bag's label is available. This comprehensive review aims to provide an in-depth analysis of the applications of MIL in cancer diagnostic tasks, highlighting its advantages, challenges, and future directions. By examining these advantages, challenges, and future trends, the review aims to contribute to advancing MIL as a powerful tool in improving cancer diagnostic accuracy and patient outcomes.
癌症患者的预后主要取决于诊断过程和治疗策略。计算机辅助诊断(CAD)方法已经证明了利用机器学习和深度学习等人工智能技术进行精确诊断的潜力。用于训练基于人工智能的模型的数据性质决定了模型的范式,通常分为有监督学习和无监督学习,分别用于有标记数据和无标记数据的场景。由于时间和资源成本的原因,如今大多数数据集都是部分标记并用于训练。弱监督学习方法能让人工智能模型在标注数据不完整、有噪声或不平衡的情况下得到训练。近年来,多实例学习(MIL)作为一种有前途的弱监督学习方法在癌症诊断等许多领域崭露头角。与传统的监督学习方法不同,MIL 允许对一组实例(称为袋)进行分类,而只有袋的标签可用。本综述旨在深入分析 MIL 在癌症诊断任务中的应用,突出其优势、挑战和未来发展方向。通过研究这些优势、挑战和未来趋势,综述旨在推动 MIL 成为提高癌症诊断准确性和患者预后的有力工具。

Multi-object tracking (MOT) is garnering more attention due to its widespread application in the area of autonomous driving, human-computer interaction, and intelligent video surveillance. Especially in recent years, MOT has rapidly developed thanks to related technologies such as object detection, which has helped in handling interfering factors such as crowded scene occlusion, small objects, and similar appearances. Among these, Detection-based MOT is the mainstream for accurately forming objects' trajectories. Therefore, according to the analysis of the last three years' research, this paper particularly focuses on discussing the continuous optimization strategies of MOT around the development of object detection at each stage. In addition, this article also introduces the commonly used benchmark datasets and related applications of MOT.

Software systems need a proper evaluation to avoid errors and problems. This research aims to showcase an evaluation method to test an integrated mobile and web application for gathering valuable feedback from Filipinos nationwide. This application, named “BOSESKO: Building on Opinions and Sentiments for Sustainability and Knowledge Opportunities” - a multilingual, inclusive, deliberative, synoptic, digital participatory toolkit, is intended to act as a central hub to solicit insights on both existing and upcoming policies in the Philippines. AppTest pertains to a comprehensive evaluation of the BosesKo software system. This research hopes to identify the strengths and weaknesses of BOSESKO and improve it, which would serve as a tool to potentially enhance civic engagement in the country by actively involving the general public in policy-making. This study employed a mixed-method approach that seamlessly integrates manual and automated testing techniques. The assessment of BOSESKO is aligned with the ISO 25010 standard, focusing on evaluating usability and performance efficiency. To delve into the usability of BOSESKO, a usability survey was administered to gauge user perspectives on (a) learnability, (b) appropriateness, (c) recognizability, (d) operability, (e) error protection, (f) user interface aesthetics, and (g) accessibility. Additionally, in-depth performance evaluations were conducted using various automated tools, including WebPageTest, PageSpeed Insight, Google Lighthouse, Yellow Lab, and Pingdom. This combination of manual and computerized methodologies provided a robust and thorough analysis of BOSESKO and, in turn, offered valuable insights into the functionality and efficiency of the developed system. As of the time of this writing, about 10,500 users across the Philippines have already engaged with BOSESKO. Initial assessment results of BOSESKO revealed an acceptable user rating with an average weighted mean of 4.36 in terms of usability. Meanwhile, the applied automated tests yielded positive performance scores of 89% and 76% for the web and mobile platforms. However, the evaluation results suggest image and search engine optimization. Overall, these results underscore the robust foundation established by BOSESKO, indicating its considerable potential and strong starting point.

Underwater communication was chiefly employed in military affairs and underwater exploration in the early days. In recent years, thanks to the progressive advancement of communication networks, many protocols have already been developed for underwater communication. However, due to technological factors, underwater communication is still looking for a seamless link to terrestrial communication. This paper proposes a novel frame format to improve the frame head of underwater communication, and presents a corresponding operation process of underwater nodes with the hope that the data link layer of the OSI 7-layer model provides the Media Access Control (MAC) protocol to the corresponding underwater network. This proposed method can be provided as a standard solution to create a seamless connection between underwater and terrestrial communication.
水下通信早期主要用于军事事务和水下勘探。近年来,由于通信网络的不断进步,已经开发出许多用于水下通信的协议。然而,由于技术因素,水下通信仍在寻求与地面通信的无缝连接。本文提出了一种新颖的帧格式来改进水下通信的帧头,并提出了相应的水下节点操作流程,希望 OSI 7 层模型的数据链路层为相应的水下网络提供媒体访问控制(MAC)协议。所提出的方法可作为标准解决方案,在水下和地面通信之间建立无缝连接。
