In silico chemotherapy optimization with genetic algorithm 基于遗传算法的计算机化学优化
Martin Ferenc Dömény, Melánia Puskás, L. Kovács, D. Drexler
The combination of medicine with engineering has great potential. The currently used chemotherapy treatments usually use maximal tolerable doses, which can lead to harmful side effects. By using a mathematical approach, we are able to personalize chemotherapy treatments, using unique patient parameters. We propose an algorithm that is capable of generating a chemotherapy treatment plan to cure cancer patients. The objective of the algorithm is to create a treatment that shrinks the tumor while minimizing the injected doses to decrease treatment costs and prevent drug toxicity. In this paper, we used a genetic algorithm to find the optimal treatment. First, we optimized the therapy on a single patient, later we carried out therapy optimization on a population with predefined ranges for the patient model parameters. The parameters are acquired from in vivo mice experiments through parametric identification. According to the results, the generated treatment produced higher survival rates with slightly higher doses compared to the standard clinically used treatment.
医学与工程学的结合具有巨大的潜力。目前使用的化疗通常使用最大耐受剂量,这可能导致有害的副作用。通过使用数学方法,我们能够个性化化疗治疗,使用独特的患者参数。我们提出了一种能够生成化疗治疗计划的算法来治愈癌症患者。该算法的目标是创造一种缩小肿瘤的治疗方法,同时最大限度地减少注射剂量,以降低治疗费用并防止药物毒性。在本文中,我们使用遗传算法来寻找最优的治疗方法。首先,我们对单个患者进行了治疗优化,然后我们对具有预定义范围的患者模型参数的人群进行了治疗优化。参数通过参数识别从小鼠体内实验中获得。根据结果,与临床使用的标准治疗相比,生成的治疗在剂量略高的情况下产生了更高的存活率。

A Novel Machine Learning Solution for the Inverse Heat Conduction Problem with Synthetic Datasets 基于合成数据集的反热传导问题的一种新的机器学习解决方案
Zoltán Biczó, S. Szénási, I. Felde
There are many attempts to solve the Inverse Heat Conduction Problem, and nowadays a growing number of machine learning-based methods have emerged. One major drawback of these methods is that they are very sensitive to the size and quality of the training database. There are several data augmentation techniques for artificially increasing the size of training databases, but these techniques have not yet been investigated in the field of quenching. This paper presents the augmentation methods that can be used, and then evaluates them with a novel experience. As a final tough, we can conclude that modern synthetic data generation can develop the robustness of machine learning methods and play an effective role in the inverse heat conduction problem occurring during the quenching of steel.

Procedural City Generation 程序城市生成
Barnabás Erdei, S. Szénási
Content creation for games and movies is expensive and time-consuming. Meanwhile, there is always a demand by the market every year for improved graphics and effects from these companies. Therefore, automated technologies are a necessity in modern workflows. With the help of procedural techniques, it is possible to accelerate and decrease the cost of this creation process. These algorithms cannot replace content creation artists because of the lack of artistic details in models like landscapes, buildings, characters, and so forth. However, it can provide a great foundation to jumpstart production projects. Because of the diversity of this topic, this paper focuses on only one of the use cases of these techniques: the generation of urban environments.
游戏和电影的内容创作既昂贵又耗时。与此同时,市场每年都有对这些公司改进图形和效果的需求。因此,自动化技术在现代工作流程中是必要的。在程序技术的帮助下,可以加速并降低此创建过程的成本。这些算法不能取代内容创作艺术家,因为在模型中缺乏艺术细节,如风景、建筑、人物等。但是,它可以为快速启动生产项目提供一个很好的基础。由于这个主题的多样性,本文只关注这些技术的一个用例:城市环境的生成。

Solving Jigsaw Puzzles Using Computer Vision and Curve Similarity Measures 用计算机视觉和曲线相似度测量解决拼图
Olivér M. Balogh, Z. Vámossy
Jigsaw puzzles are a popular form of entertainment. Solving them with the help of computers raises several interesting problems, and has been the subject of many published papers in the past. In this paper, an approach to creating a program that uses pictures of real puzzle pieces to reconstruct the full puzzle image is presented. A photography technique is described that results in consistently recognizable images, which are used to extract features of the puzzle pieces. These features are then compared using two similarity algorithms - Hausdorff distance and Dynamic Time Warping. Three different puzzle assembly strategies that use these comparisons are presented, along with additional logic rules to solve the full puzzle. Using these the final program is capable of solving two different, 25-piece jigsaw puzzles. A comparison of the different similarity measures and assembly algorithms in the scope of the problem is also presented.

Determination of Rainfall Probability Using Response Surface Method 用响应面法确定降雨概率
Júlia Zombori, J. Lukács, R. Horváth
Forecasting rainfall is a major challenge, but it would be important as rainfall has a huge effect on the economy and food crises around the world. Currently, there are many mathematical models for weather forecast and for precipitation. Due to the phenomenon of desertification, precipitation forecasting is becoming increasingly important. In this article, a case study is presented on estimating the probability of rainfall using response surface method (RSM). After analyzing real data, a third-order surface model is presented for estimating the rainfall probability (the input parameters are the daily average temperature and the daily average humidity, and the output parameter is the summarized amount of the daily rainfall). It can be revealed that the presented method can be suitable for describing the real-time data used with sufficient accuracy. This study shows the efficiency and the applicability of RSM method for rain predicting.

Perception of innovation and innovative projects at user level through the example of the Atala Prism project 通过Atala Prism项目的例子,在用户层面对创新和创新项目的认识
J. Varga, Ágnes Csiszárik-Kocsir
The success of any project lies in its acceptance by the end users. For novel initiatives, user acceptance is an even greater risk than for other, ordinary, normal projects. For a novelty to be accepted by users, adopted by other organisations, economic actors and widely used, it needs to be a resounding success. Innovative initiatives affect all sectors of the economy, and education is no exception. The aim of this paper is to illustrate the role of innovative projects and their perception by users through the example of a project considered to be an international example. The project will be presented from the users’ point of view, from the stakeholders’ point of view, through some characteristics of the project scope, highlighting the factors that make it usable and attractive, based on the results of a questionnaire survey.
任何项目的成功都取决于最终用户的接受程度。对于新颖的计划,用户接受的风险甚至比其他普通的正常项目更大。一个新事物要被用户接受,被其他组织和经济参与者采用,并被广泛使用,它需要取得巨大的成功。创新举措影响到经济的各个部门,教育也不例外。本文的目的是通过一个被认为是国际范例的项目的例子来说明创新项目的作用和用户对它们的看法。项目将从用户的角度,从利益相关者的角度,通过项目范围的一些特征,突出使其可用和有吸引力的因素,基于问卷调查的结果。

The effects of shoes with a triple density midsole on lower limb kinematics and kinetics in male recreational runners 三密度中底鞋对男性休闲跑步者下肢运动学和动力学的影响
X. Jiang, István Bíró
Cushioned or stability running shoes is currently a highly debated topic among runners and researchers. Several footwear companies have developed running shoes to simulate different hardness but few studies have compared a triple density running shoe to deduce the injuries of running. The primary goal of this study was to compare acute changes in three-dimensional (3D) ground reaction forces (GRFs) and lower limb kinematics of habitually shod rear-foot strike (RFS) runners between different hardness and density running shoes. Lower limb joint biomechanical variables of fifteen recreational runners were analyzed using a 3D motion capture system and a force platform. The loading rate at the first impact peak showed no difference between the two shoe conditions. The first impact peak was significantly larger in the triple density shoe condition than in the single density shoe. Combining the inversion and eversion of the ankle during the pushing-off phase, a single midsole showed a bigger eversion angle than a density midsole. The innovative running shoes enhanced the rear-foot stability of runners compared to the control running shoe during the loading (eversion) phase of running.
缓震跑鞋或稳定跑鞋目前是跑步者和研究人员之间一个备受争议的话题。一些鞋类公司已经开发出模拟不同硬度的跑鞋,但很少有研究比较三密度跑鞋来推断跑步的伤害。本研究的主要目的是比较不同硬度和密度跑鞋对习惯性穿后足撞击(RFS)跑步者的三维(3D)地面反作用力(GRFs)和下肢运动学的急性变化。采用三维运动捕捉系统和受力平台对15例休闲跑步者下肢关节生物力学变量进行了分析。两种鞋型在第一个冲击峰处的加载速率没有差异。三密度鞋的第一次冲击峰明显大于单密度鞋。结合踝关节在蹬脱阶段的内翻和外翻,单中底比密度中底显示出更大的外翻角度。与常规跑鞋相比,创新跑鞋在跑步加载(版本)阶段增强了跑步者的后脚稳定性。

AI-Augmented Peer Led Team Learning for STEM Education 人工智能增强的STEM教育同伴领导的团队学习
K. Dsouza, Lin Zhu, P. Varma-Nelson, S. Fang, S. Mukhopadhyay
Active learning methodologies in higher education benefit students by reinforcing learning and critical skills during the class. In active pedagogical models such as Peer-Led Team Learning (PLTL) students have stronger course outcomes. The instructor is not present in a PLTL workshop and may not receive sufficient feedback from peer leaders. Additionally, these classes have large enrollments. There is a lack of AI-enabled tools that monitor or provide feedback during cPLTL workshops. The current study addresses this gap by proposing an AI-based multimodal solution using recordings of cyber Peer-Led Team Learning (cPLTL) classes. The machine learning model analyzes audio and text features to predict the outcome of a workshop. The results using multimodal learning show potential for further development of the tool. Such improved modeling will help reduce the instructor’s workload facilitating the integration of AI in education. This novel multimodal approach aims to enhance the student’s learning experience by providing an automated feedback mechanism to the instructor.
高等教育中的主动学习方法通过在课堂上加强学习和关键技能使学生受益。在积极的教学模式中,如同伴领导的团队学习(PLTL),学生的课程成果更强。讲师不在PLTL研讨会上,可能无法从同行领导那里得到足够的反馈。此外,这些课程的注册人数很大。在cPLTL研讨会期间,缺乏支持人工智能的工具来监控或提供反馈。目前的研究通过使用网络同伴领导的团队学习(cPLTL)课程的录音,提出了一种基于人工智能的多模式解决方案,解决了这一差距。机器学习模型分析音频和文本特征来预测研讨会的结果。使用多模态学习的结果显示了该工具进一步发展的潜力。这种改进的建模将有助于减少教师的工作量,促进人工智能在教育中的整合。这种新颖的多模式方法旨在通过向教师提供自动反馈机制来提高学生的学习体验。

Method for Autonomous Lane Detection in Assisted Driving 辅助驾驶自动车道检测方法
Maria C. Brad, A. A. Brad, M. Micea
This paper presents a machine learning-based method for detecting lanes on roads. The proposed approach includes several processing steps such as preprocessing of the original image frames, application of the Hough Line Transform for an initial detection of lanes, computation of the vanishing point to determine the horizon line, and region of interest (ROI) determination. Additionally, the method compensates for the unknown position of the camera facing the road by cropping a triangle-shaped perspective area. To correct errors caused by road discoloration and cracks, a color mask for white and yellow pixels is used. The orientation of the lanes is determined by analyzing the slope of the lines, and the lane coordinates are linked to the image center. The proposed method uses the U-Net neural network and the implementation is based on the Python programming language and OpenCV image processing library. In the final section we also present a comparison with a lane detection method based on convolutional neural networks and discuss the results.
本文提出了一种基于机器学习的道路车道检测方法。该方法包括对原始图像帧进行预处理,应用霍夫线变换进行车道的初始检测,计算消失点以确定地平线,确定感兴趣区域(ROI)等几个处理步骤。此外,该方法通过裁剪一个三角形透视区域来补偿摄像机面对道路的未知位置。为了纠正由道路变色和裂缝引起的错误,使用白色和黄色像素的颜色蒙版。通过分析线的斜率确定车道的方向,并将车道坐标链接到图像中心。该方法采用U-Net神经网络,基于Python编程语言和OpenCV图像处理库实现。在最后一节中,我们还与基于卷积神经网络的车道检测方法进行了比较,并讨论了结果。

Deep learning for 5G and 6G 5G和6G的深度学习
S. Ardabili, Amir H. Mosavi, I. Felde
Deep learning (DL) is a promising technology for enhancing the development of fifth generation (5G) and sixth generation (6G) mobile networks, as it can improve their capabilities, security, and performance. However, there are still significant challenges to be addressed in the implementation of DL techniques in these networks. To address these challenges, we conducted a systematic review of the literature on DL techniques in 5G and 6G applications following the PRISMA guidelines. The review was conducted in three stages: data collection, analysis, and reporting of primary findings. After evaluating and reviewing the databases, we found that hybrid DL and ensemble techniques show promise in optimizing 5G and 6G networks, given proper implementation. Finally, we discussed the open issues and challenges in this field. This review provides important insights into the potential of DL techniques in improving 5G and 6G networks, and it highlights the need for further research to overcome the remaining challenges. The results of this primary communication will be further developed and extended into a journal article.
深度学习(DL)可以提高第五代(5G)和第六代(6G)移动网络的能力、安全性和性能,是促进第五代(5G)和第六代(6G)移动网络发展的有前途的技术。然而,在这些网络中实现深度学习技术仍然存在重大挑战需要解决。为了应对这些挑战,我们根据PRISMA指南对5G和6G应用中的DL技术文献进行了系统回顾。审查分三个阶段进行:数据收集、分析和报告主要发现。在评估和审查数据库后,我们发现混合深度学习和集成技术在优化5G和6G网络方面表现出希望,只要实施得当。最后,讨论了该领域存在的问题和面临的挑战。这篇综述为深度学习技术在改善5G和6G网络方面的潜力提供了重要见解,并强调了进一步研究以克服剩余挑战的必要性。这次初步交流的结果将进一步发展并扩展到期刊文章中。
