What Represents Value and Happiness for the Hungarian Generation Z in 2022-2023? 2022-2023年匈牙利Z世代的价值和幸福是什么?
K. Jäckel, Mónika Garai-Fodor
Our qualitative research was inspired by the 75-year long Harvard University Happiness Survey.In October-November 2022, 65 young marketing undergraduates from Generation Z were asked what value and happiness meant to them. Today’s 20-year-olds were forced to live one tenth of their lives, i.e., 2 years, locked in their homes, isolated from friends and university peers, during the COVID -19 pandemic. Hardly had they recovered from the threat of the pandemic, from their grief, when they were hit by another trauma, as were other members of society. War in neighbouring Ukraine, serious energy crisis, climate crisis, skyrocketing inflation, uncertain future…The focus of the research was therefore on the question of what kind of life they would be satisfied with, and what they would do to achieve the quality of life they want. What goals do they have, what do they want to achieve in their lives? Are human relationships important to them? As our interviewees were marketing students, we asked them if they were happy buying a product or using a service, how important is the experience of buying a product or service to them? How do they think about this topic, what strategy do they want to follow as marketing employees based on their life experiences? Their way of thinking is also decisive at a societal level.
我们的定性研究受到了长达75年的哈佛大学幸福调查的启发。在2022年10月至11月,65名来自Z世代的年轻营销本科生被问及对他们来说价值和幸福意味着什么。在2019冠状病毒病大流行期间,今天20多岁的年轻人被迫将生命的十分之一(即2年)锁在家中,与朋友和大学同学隔绝。他们刚从大流行病的威胁中恢复过来,刚从悲痛中恢复过来,就像其他社会成员一样,受到了另一种创伤的打击。邻国乌克兰的战争、严重的能源危机、气候危机、暴涨的通货膨胀、不确定的未来……因此,研究的重点是他们会对什么样的生活感到满意,以及他们会做些什么来实现他们想要的生活质量。他们有什么目标,他们想在生活中实现什么?人际关系对他们重要吗?由于我们的受访者是市场营销专业的学生,我们问他们是否乐于购买产品或使用服务,购买产品或服务的体验对他们来说有多重要?他们如何看待这个话题,根据他们的生活经历,作为营销员工,他们想遵循什么样的策略?他们的思维方式在社会层面上也是决定性的。

Automotive Scenarios for Trajectory Tracking using Machine Learning Techniques and Image Processing 使用机器学习技术和图像处理的轨迹跟踪的汽车场景
Delia Moga, I. Filip
This paper presents a study on using innovative machine learning techniques that can be applied in automotive traffic scenarios to increase a vehicle’s level of autonomy. The overtaking traffic scenario is treated for predicting the vehicle trajectory when overtaking another vehicle and the data is obtained by image processing using a video camera. Two different methods are compared, first by using classic tracking methods and a Kalman filter (as an adaptive filter) and second by using a machine learning technique - Support Vector Machine. The present article uses as inputs the data received from the camera and focuses on tracking selected objects and estimating their position using mainly image processing in automotive scenarios. The main purpose of this work is to experiment and compare different tracking modes to determine those that have the best performances in terms of runtime, memory usage and prediction accuracy.

Indirect supervised fine-tuning of a tumor model parameter estimator neural network 肿瘤模型参数估计神经网络的间接监督微调
Lilla Kisbenedek, Melánia Puskás, L. Kovács, D. Drexler
Personalized therapy based on mathematical foundations is a promising method for treating various types of cancer. By identifying the parameters of mathematical equations, we could gain more information about the patients and the tumor. In previous works, a vast number of training data of virtual scenarios has been generated, then used to train a neural network to predict parameters. Besides the fact that in silico experiments have been used, and the actual parameters can differ from them, the algorithm still can be utilized for initial estimation. The main objective of this work is to find the parameters of living mice, by taking advantage of the learning capability of neural networks. As a result, the implementation encompasses two main stages. First, we created another supervised neural network, that is able to solve the applied differential equations faster with fewer algebraic steps, than the traditionally used ODE solvers. Then, we find a better-fitting parameter set for the real measurement, while we retrain the original network with these parameters and the associated error, without forgetting the already learned weights from in silico experiments. The results indicate that the implemented model can be used in further research as an unconstrained optimization technique for parameter fitting.
基于数学基础的个性化治疗是治疗各种类型癌症的一种很有前途的方法。通过识别数学方程的参数,我们可以获得更多关于患者和肿瘤的信息。在以往的工作中,已经生成了大量的虚拟场景的训练数据,然后用来训练神经网络来预测参数。除了已经在计算机上进行了实验,并且实际参数与实验结果可能存在差异之外,该算法仍然可以用于初始估计。本工作的主要目的是利用神经网络的学习能力,找到活体小鼠的参数。因此,实现包含两个主要阶段。首先,我们创建了另一个监督神经网络,与传统的ODE求解器相比,它能够以更少的代数步骤更快地求解应用的微分方程。然后,我们为实际测量找到一个更好的拟合参数集,同时我们用这些参数和相关误差重新训练原始网络,同时不忘记已经从计算机实验中学习到的权重。结果表明,所实现的模型可以作为参数拟合的无约束优化技术用于进一步的研究。

The impact of age on NBA player’s performances: A Data Mining approach 年龄对NBA球员表现的影响:一种数据挖掘方法
Bence Richard Hach, Lucian Ionel Gaina, D. Stanescu, Bianca Gusita
In the National Basketball Association (NBA), understanding how age impacts player performance is crucial for team general managers and coaches, allowing them to construct the most competitive rosters. This research paper aims to investigate the relationship between the player’s performances and their age by clustering the players into six groups based on their ages and comparing their performance indicators. For each group, multiple widely known indicators as the Individual Player Efficiency (EFF) and Player Efficiency Rating (PER), were used. Experimental results show the age at which players commonly reach peak performance levels. Using these results, general managers have a cutting edge when searching for new players to enhance their team performance.
在美国职业篮球联赛(NBA)中,了解年龄对球员表现的影响对球队总经理和教练来说至关重要,这有助于他们构建最具竞争力的阵容。本研究的目的是通过将球员按年龄分为6组,并比较他们的表现指标,来研究球员的表现与年龄之间的关系。对于每一组,我们使用了多个广为人知的指标,如个人玩家效率(EFF)和玩家效率评级(PER)。实验结果表明,球员通常在这个年龄达到最佳表现水平。利用这些结果,总经理在寻找新球员以提高球队表现时具有领先优势。

Options Evaluator With an Artificial Intelligence-Based Volatility Model 基于人工智能波动率模型的期权评估器
Árpád Rigó, B. Tusor
The subject of this paper is an options modeling system, which aims to provide the most accurate profit forecast possible for options portfolios in a comprehensible form, as software on the market will misrepresent this in the absence of accurate implied volatility data, which can put trading success at risk. The software determines future implied volatility from 1-year historical options on VXX stock with 6 samples per trading day using statistics and a deep neural network (Long short-term memory LSTM). Using this statistical approach and the trained volatility model, the system calculates the profit/loss curve, thus providing a more accurate picture of the possible future outcomes of a given portfolio.
本文的主题是一个期权建模系统,旨在以一种可理解的形式为期权投资组合提供最准确的利润预测,因为市场上的软件在缺乏准确的隐含波动率数据的情况下会歪曲这一点,这可能会使交易成功面临风险。该软件利用统计数据和深度神经网络(长短期记忆LSTM),从VXX股票的1年历史期权中确定未来隐含波动率,每个交易日有6个样本。利用这种统计方法和经过训练的波动率模型,系统可以计算出盈亏曲线,从而更准确地描述给定投资组合的未来可能结果。

Carpentry software designing and development with pane cutting optimization functionality 木工软件的设计和开发与窗格切割优化功能
Bence Hodák, Elemér Balázs
In this paper, a carpenter software is designed and implemented that supports the daily management processes (customers, orders, inventory) and generates a pattern from the product descriptions based on the parameters specified. During the pattern generation process, a two-dimensional optimization is performed to generate a pattern that includes horizontal or vertical cuts, depending on the target machine, on which the position of the required parts is placed, generates the smallest material loss and uses leftover materials from the past. From the application, the pattern can be viewed and extracted online or in PDF format. This all is implemented in a layered web application with a modern approach.

Pharmacodynamics modeling based on in vitro 3D cell culture experiments 基于体外三维细胞培养实验的药效学建模
Borbála Gergics, F. Vajda, Alexander Ládi, András Füredi, D. Drexler
Optimized therapies for the individual patient provide a more cost-effective, more secure method of chemotherapy. Therapy optimization demands a reliable mathematical model of tumor growth, pharmacodynamics, and the effect of the chemotherapeutic agent used during the therapy. Examining these effects and processes in vitro cell culture experiments maintain a cheaper and more ethical method to create tumor growth and pharmacodynamics models and estimate their parameters. In this work, parameter identification was carried out by using cytotoxicity measurements of two- and three-dimensional (spheroid) tumor cell cultures. In vitro experiments were accomplished on mice breast cancer cell line. Four experiments were done: two experiments on two-dimensional cell cultures, with the initial number of 5000 and 10000 cells, and two experiments on three-dimensional spheroid cell cultures, with the initial number of 5000 and 10000 cells. The drug used was Doxorubicin at the same serial dilution in all cases. Parameter identification was performed by fitting to fluorescent intensity confluence data measured by an automatic time-lapse microscope for five days. We compared the results of two- and three-dimensional cell cultures and identified the model parameters in all four cases. The value of the sum square error showed that the fitting and identification performed better in the case of tumor spheroid cultures.
针对个别患者的优化疗法提供了一种更具成本效益、更安全的化疗方法。治疗优化需要一个可靠的肿瘤生长、药效学和治疗过程中使用的化疗药物效果的数学模型。在体外细胞培养实验中检查这些影响和过程,为建立肿瘤生长和药效学模型并估计其参数提供了一种更便宜、更合乎道德的方法。在这项工作中,通过使用二维和三维(球形)肿瘤细胞培养的细胞毒性测量来进行参数识别。在小鼠乳腺癌细胞系上进行了体外实验。共进行了4个实验:2个二维细胞培养实验,初始数量分别为5000和10000个细胞;2个三维球体细胞培养实验,初始数量分别为5000和10000个细胞。在所有病例中,所使用的药物均为相同系列稀释度的阿霉素。通过拟合自动延时显微镜测量的5天荧光强度合流数据进行参数识别。我们比较了二维和三维细胞培养的结果,并确定了所有四种情况下的模型参数。平方和误差值表明,在肿瘤球体培养的情况下,拟合和识别效果较好。

Detection of Attacks in Software-Defined Networks (SDN)* : *How to conduct attacks in SDN environments SDN (Software-Defined Networks)攻击检测*:*如何在SDN环境下进行攻击
Jean Rosemond Dora, L. Hluchý
Over decades, the software-defined network commonly named SDN has been prioritized by many industries and academia over traditional networks. The SDN properties offer better security of the managed network and offer better network monitoring. However, its popularity has been drawn drastically to attackers’ attention. In this paper, we evaluate the security posture of the SDN networks and prove that they are subject to several vulnerabilities by simulating attacks against devices in the network. Abusing those weaknesses can jeopardize the company’s reputation as well as its financial situation. Therefore, to achieve the exploitation, we simulate the attacks using Mininet and RYU controller tools. Additionally, we briefly talk about the mitigation techniques as we will deal with them in our future work.
几十年来,通常被称为SDN的软件定义网络已经被许多行业和学术界优先考虑,而不是传统网络。SDN的特性为被管理网络提供了更好的安全性和更好的网络监控。然而,它的流行已经引起了攻击者的极大注意。在本文中,我们评估了SDN网络的安全态势,并通过模拟对网络中设备的攻击来证明SDN网络存在几个漏洞。滥用这些弱点可能会危及公司的声誉和财务状况。因此,为了实现利用,我们使用Mininet和RYU控制器工具模拟攻击。此外,我们将简要讨论缓解技术,因为我们将在未来的工作中处理它们。

Safe trajectory design for indoor drones using reinforcement-learning-based methods 基于强化学习方法的室内无人机安全轨迹设计
Dénes Tompos, B. Németh
This paper proposes a design method for achieving safe trajectory of indoor drones. The trajectory design with a reinforcement-learning-based (RL) agent is facilitated, which can result in efficient and collision-free motion. The method is developed for motion in indoor area with moving mobile robots, and thus, the collision with these obstacles must be avoided. Through RL-based design the fast motion of the drones can be achieved, which must perform a mission between workstations in a manufacturing system. The effectiveness of the design process through a simulation example on a real laboratory environment is illustrated.

The effectiveness of the design process through a simulation example on a real laboratory environment is illustrated.","PeriodicalId":339156,"journal":{"name":"2023 IEEE 17th International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"216 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114816441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jaycustomers in the Hungarian healthcare system 匈牙利医疗保健系统的jaycustomer
K. Jäckel, Mónika Garai-Fodor, Zoltán Gábor Lukács
The objective of our research was to examine the jaycustomers in healthcare. Thematic qualitative interviews were conducted with frontline healthcare staff (doctors, healthcare workers - nurses, caretakers and pharmacists). The respondents were asked to recall extraordinary situations and events. Based on the events, we asked them to describe the unpleasantness of the situation and then classify the healthcare jaycustomers. Our goal with this research is to explore the most common conflict situations in healthcare, the causes, the characteristics of destructive/deviant users, in order to formulate recommendations to service providers on how to deal with these jaycustomer types. The practical applicability of the research therefore lies in its potential to help develop proactive service provider behaviour. The identification of conflict situations allows quality improvement procedures to regulate where defects arise. 46 physicians, pharmacists/pharmacy staff, nurses, nurse practitioners, medical assistants and ambulance nurses were interviewed in September-November 2022.
我们研究的目的是检查医疗保健行业的jaycustomer。对一线医护人员(医生、医护人员——护士、护工和药剂师)进行了专题定性访谈。受访者被要求回忆特别的情况和事件。根据这些事件,我们要求他们描述不愉快的情况,然后对医疗保健jaycustomer进行分类。本研究的目的是探讨医疗保健中最常见的冲突情况,其原因,破坏性/越轨用户的特征,以便为服务提供者制定如何处理这些jaycustomer类型的建议。因此,该研究的实际适用性在于其帮助发展主动服务提供者行为的潜力。冲突情况的识别允许质量改进程序来规范缺陷出现的地方。在2022年9月至11月期间对46名医生、药剂师/药房工作人员、护士、执业护士、医疗助理和救护车护士进行了访谈。
