Following recent trends, it appears that robot presence within human day-to-day lives is likely to grow and become ubiquitous. As many actors are engaged in this automation effort, it is plausible that the various cultural backgrounds of these actors will result in a broad range of different robots that will nevertheless need to perform similar tasks. Due to the excessively large number of experiences samples needed to successfully train a learning-based control policy, it would be remarkably useful to be able to efficiently transfer the skills acquired by a given agent to other, structurally distinct, robots. Accordingly, the BAM (Base-Abstracted Modeling) methodology proposed in this paper is a fast transfer learning approach that relies on a clear segmentation between the task model, that is a learned policy for solving a specific task and the learned robot control policy. The evaluation on two manipulation tasks using twelve different configurations of mobile manipulators demonstrates the strong potential of this approach as the segmentation results for more robust policies than naive methods and that an efficient transfer can be done in a fraction of the initial training time.
按照最近的趋势,机器人在人类日常生活中的存在似乎会越来越多,变得无处不在。由于许多参与者都参与了这项自动化工作,因此这些参与者的不同文化背景将导致各种不同的机器人需要执行类似的任务,这是合理的。由于成功训练基于学习的控制策略需要大量的经验样本,因此能够有效地将给定代理获得的技能转移到其他结构不同的机器人上将非常有用。因此,本文提出的基础抽象建模(BAM)方法是一种快速迁移学习方法,它依赖于任务模型之间的明确分割,即解决特定任务的学习策略和学习到的机器人控制策略。对使用12种不同配置的移动机械手的两个操作任务的评估表明,该方法具有强大的潜力,因为该方法的分割结果比原始方法更具鲁棒性,并且可以在初始训练时间的一小部分内完成有效的转移。

Humans nowadays are tending to spend too much time in front of their screens. Direct interaction between humans is falling in numbers and people are losing their empathic behaviour. By integrating empathy and emotions in everyday objects researchers can address this problem. In addition we can have a positive effect on our lives, from physical and mental health through tackling many issues, like productivity, time wasting, stress and other problems. In this article, we tackle the productivity problem by presenting the Empathic Flower Companion (EFC) that will be using the expression of emotions to help the human through their working day. It will be monitoring their time and at the same time analysing the websites they will be surfing. The concept proposed will reduce the time wasted on unproductive websites. The results show an increase of 15% in the productivity of the testers, which shows that EFC was effective in reducing the amount of time wasted.
如今,人们倾向于在屏幕前花费太多时间。人与人之间的直接互动正在减少,人们正在失去他们的移情行为。通过将同理心和情感融入日常物品中,研究人员可以解决这个问题。此外,我们可以对我们的生活产生积极的影响,从身体和精神健康通过解决许多问题,如生产力,时间浪费,压力和其他问题。在这篇文章中,我们通过介绍移情花伴侣(EFC)来解决生产力问题,EFC将使用情感表达来帮助人类度过他们的工作日。它将监控他们的时间,同时分析他们将浏览的网站。提出的概念将减少浪费在非生产性网站上的时间。结果表明测试人员的生产率提高了15%,这表明EFC在减少浪费的时间方面是有效的。

Software developers use metrics to estimate the software quality before the development stage to impact early decision making at the requirement stage, development quantification, operation, and software maintenance. These metrics give knowledge of certain attributes of the software system and thus help to evaluate it objectively and give opportunities for software improvement and making plans for modifications. The application development is supposed to be performed using the OETPN based modeling method. The newly proposed metrics are: Structural Complexity (number of arcs and the number of modules), Hierarchical Complexity (if one OETPN module is created by another), Unstructuredness of OETPN Models (which is based on the number of modules, cycles and decision places), Branching Complexity (which is computed according to the reachability graph), Decision Vertex (which is computed based on the decision node of the execution graph), and the Net Complexity (the summation of all the previous complexities).
软件开发人员在开发阶段之前使用量度来评估软件质量,以影响需求阶段、开发量化、操作和软件维护的早期决策制定。这些度量给出了软件系统的某些属性的知识,从而帮助客观地评估它,并为软件改进和制定修改计划提供了机会。应用程序开发应该使用基于OETPN的建模方法来执行。新提出的指标是:结构复杂度(圆弧数和模块数)、层次复杂度(如果一个OETPN模块是由另一个OETPN模块创建的)、OETPN模型的非结构化性(基于模块数、循环数和决策位置)、分支复杂度(根据可达性图计算)、决策顶点(根据执行图的决策节点计算)和净复杂度(之前所有复杂性的总和)。

In this work, we propose a method based on the unified particle swarm optimization (UPSO) for no-wait multi-hoist scheduling, including a collision avoidance heuristic. Conflicts due to track sharing between hoists and no-wait constraints represent major issues to be addressed. Consequently, a complex optimization problem has to be solved dynamically, to identify the best operating strategy to be executed depending on the characteristics of the current job list. A decomposition procedure has been developed to speed up the solution of the large-scale optimization problem at hand. The proposed approach is demonstrated on a real galvanic process layout, showing the improved performances achieved by the proposed heuristic compared to the monolithic approach.
本文提出了一种基于统一粒子群优化(UPSO)的多提升机无等待调度方法,并引入了避碰启发式算法。由于起重机之间的轨道共享和无等待约束导致的冲突是需要解决的主要问题。因此,必须动态地解决复杂的优化问题,以根据当前作业列表的特征确定要执行的最佳操作策略。为了加速求解手头的大规模优化问题,开发了一种分解程序。该方法在实际的电偶工艺布局中得到了验证,与单片方法相比,该方法的性能得到了改善。

The use of bio-inspired algorithms into controller tuning is one of the main topics in the last decades. One crucial issue when using bio-inspired algorithms to on-line tune the control system (adaptive controller tuning) is the computational time. In this work, an Asynchronous Adaptive Controller Tuning (AACT) approach is proposed to reduce the frequent activation of the tuning process, and hence, the computational cost could be reduced. This approach is based on a proposed event function, which determines the update time instant of the control parameters through the Differential Evolution algorithm. Comparative results with a Synchronous Adaptive Controller Tuning (SACT) approach are included in the study case of the speed regulation of the DC motor under the effects of uncertainties in the load. The SACT approach periodically updates the controller parameter at each sampling time. The comparative analysis indicates that the proposed AACT significantly reduces the controller parameter update without considerably increase the regulation error.

The recent development in the field of smart meters has resulted in a large amount of electricity consumption profile which can be forecasted and analyzed for better planning of grid such as load scheduling, demand-side management, etc. In this paper, a Dynamic Mode Decomposition (DMD) for forecasting of grid profile for a specified time period is proposed. The key feature of the DMD technique is that it utilizes the past data for the prediction of future data without the need for the system model. Once the load profile is forecasted using DMD, the peak loads and base load time period are segregated. With the help of a system operator, various energy sources can be arranged for supplying peak loads. Electric vehicles (EVs) having the advantage of mobility and smart building acting as the virtual battery is considered for providing support to the grid as compared to other renewable energy sources which generally have limitations due to environmental factors. The DMD technique for forecasting the load profile of the smart grid is tested under various test scenarios. Finally, from the results, it has been proved that EVs and the smart building seem to be the most promising solution for supporting the grid during the peak load period.
近年来,智能电表领域的发展带来了大量的电力消耗数据,这些数据可以进行预测和分析,从而更好地规划电网,如负荷调度、需求侧管理等。本文提出了一种基于动态模态分解(DMD)的特定时间段网格轮廓预测方法。DMD技术的主要特点是,它利用过去的数据来预测未来的数据,而不需要系统模型。一旦使用DMD预测了负荷概况,峰值负荷和基本负荷时间段就会被隔离。在系统操作员的帮助下,可以安排各种能源供应高峰负荷。与其他可再生能源相比,具有移动性和智能建筑优势的电动汽车(ev)被认为是为电网提供支持的虚拟电池,而其他可再生能源通常由于环境因素而受到限制。在各种测试场景下,对DMD技术用于智能电网负荷预测进行了测试。最后,从结果来看,电动汽车和智能建筑似乎是最具前景的解决方案,以支持电网在高峰负荷期间。

This paper deals with stabilizing spatial motion of a maneuverable aircraft with three controls and nine state parameters. It is required to provide specified dynamic properties of the controlled plant at minimal control actions.To solve the assigned task the modification of the Bass – Gura formula is suggested, which allows analytically synthesizing stabilizing modal control for multi-input objects and simplifies parameterization of this control.For numeric matrices describing one of flight modes of the typical maneuverable aircraft and for required dynamic properties of the closed-loop control system a parameterized analytic solution of the considering problem is obtained in the form of controller matrix. A control law providing small values of state vector components and of controls shifts is synthesized by choosing the parameters minimizing the sum of controller coefficients absolute values. The simulation results are shown.

In the electro-mobility sector there is a rising necessity of providing new infrastructures, services, tools and solutions to support the diffusion of electric vehicles (EVs). In this framework, this paper aims to propose an innovative service that can improve the experience of electric vehicle users by providing customized information to reduce the range anxiety risk before starting the trip. In particular, an Information Technology (IT) service based on cooperative virtual sensors (VSs) is designed to predict the charge demand by an electric vehicle, driven by a specific user, to accomplish a predefined trip. To this goal, three virtual sensors are designed as software components each one implementing an algorithm to perform a specific task. It is shown how the cooperation of the three VSs is necessary to achieve the final service objective that is to provide customized information to help the user in preparing the EV for the trip. In addition, the effectiveness of the proposed service is demonstrated through a use case implemented by the developed IT application prototype.

To this goal, three virtual sensors are designed as software components each one implementing an algorithm to perform a specific task. It is shown how the cooperation of the three VSs is necessary to achieve the final service objective that is to provide customized information to help the user in preparing the EV for the trip. In addition, the effectiveness of the proposed service is demonstrated through a use case implemented by the developed IT application prototype.","PeriodicalId":355781,"journal":{"name":"2020 7th International Conference on Control, Decision and Information Technologies (CoDIT)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127543982","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}

This paper presents the model of intersection controllers using timed automata and colored Petri nets formalisms. The models include cars control, pedestrians control, vehicles detection system and failure diagnosis with subsequent control changes. The validation and verification of the models has been realized in UPPAAL Pro model-checker and CPN Tools. The proposed modeling framework is applied to real intersections located in Bratislava and Malacky, Slovakia.
