Aiming to solve this problem, this paper proposes a novel Transfser Learning (TL) framework with Dynamic Multiscale Representation (DMR) for fault diagnosis. This model draws the inspiration from the shared learning and transfer learning, processing information captured and exploited by multiscale signal factors. In particular, a novel multi-path merging network is proposed to generate dynamic weights for fusing multiscale factors. To drive this generation, and to control the extent of the shared fusion, the Multi-gate Mixture-of-Experts (MMoE) is introduced to model the tradeoff between scale-specific representation and inter-scale correlation. A transfer learning backend is also introduced to align cross-domain features, which enables proposed method to diagnose faults across distinct working conditions. Experiments evaluate the fault-diagnosis performance. Our primary, ablation and interpretation evaluations comprehensively indicate the robustness and flexibility of the proposed method to diverse fault diagnosis applications. Especially, the proposed method achieves 4.71% and 3.86% improved to the second best one (MSSLN) on the PHM2009 and MCP datasets, respectively.</p></div>","PeriodicalId":100288,"journal":{"name":"Cognitive Robotics","volume":"3 ","pages":"Pages 257-264"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49710708","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}

In particular, this study focuses on the initial or final posture of actions and provides a computational tool that allows an agent to evaluate their feasibility and appropriateness. Such tool is a kinematic network, equivalent to an internal body schema, that allows a cognitive agent to generate simulation-states that reach the goal with a comfortable final posture, by exploiting the redundancy of the kinematic network. This is obtained by activating and integrating in the network dynamics three types of virtual force fields: 1) Focal force field applied to the end-effector, related to the goal of the action; 2) Range of Motion force fields, applied separately and independently to each degree of freedom in order to preserve the natural joint limits; 3) Postural force field, applied to the pelvis area, for maintaining the projection of the center of mass of the body model inside the support base. The efficacy of this approach is demonstrated in relation to a simple task: reaching a heavy load in order to lift it and then shifting it forward before dropping it on a table. The mental simulation model attempts to provide a kinematic template compatible with the overall plan and the postural/articular constraints, as a function of the initial position of the body relative to the load. The simulation may fail and this indicates that the chosen initial posture is inappropriate for the task. Successful simulations can also be evaluated in terms of precision and effort by monitoring the peak torque required of each joint actuator. Optimal or at least sub-optimal solutions can be memorized in episodic memory, thus accruing the know-how of the agent.</p></div>","PeriodicalId":100288,"journal":{"name":"Cognitive Robotics","volume":"3 ","pages":"Pages 185-200"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49761359","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}

While Digital Twin can represent digital objects, they are often used to connect the physical and digital worlds. This technology plays a vital role in fulfilling various requirements of Industry 4.0. It gives a digital image of a factory's operations, a communications network's activities, or the movement of items through a logistics system. This paper studies Digital Twin and its need in Industry 4.0. Then the process and supportive features of Digital Twin for Industry 4.0 are diagrammatically discussed, and finally, the major applications of Digital Twin for Industry 4.0 are identified. Digital Twin sophistication depends on the process or product represented and the data available. Manufacturers can learn how assets will behave in real-time, in the physical world, by putting sensors on particular assets, gathering data, creating digital duplicates, and employing machine intelligence. They can confidently make wise judgments, which helps improve company performance. Digital Twin assesses material usage to save costs, discover inefficiencies, replicate tool tracking systems, and do other things. Manufacturers construct a digital clone for specific equipment and tools, exclusive products or systems, entire procedures, or anything else they want to improve on the factory floor. Sensors and other equipment that collect real-time data on the state of the process or product collect this information, which on the other hand, must be handled and processed appropriately. It is made feasible by IoT sensors, which collect data from the physical environment and transmit it to be virtually recreated. This information comprises design and engineering details that explain the asset's shape, materials, components, and behaviour or performance.</p></div>","PeriodicalId":100288,"journal":{"name":"Cognitive Robotics","volume":"3 ","pages":"Pages 71-92"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49710581","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}

Analytical results clarified that meaningful contribution of payload weight to the motion resistance force (15.26–28.05 N) was marginal (< 8 times) in comparison with that of robot forward speed. Hence, adjustment of the forward speed than payload weight is suggested as priority. Modeling results described that combinatorial effect of robot forward speed and payload weight on the motion resistance force was synergetic. This disclosed linear increasing dependency of the motion resistance force on concurrent proliferation of robot forward speed and payload weight.

To address the privacy leakage in location services, this paper proposes a location privacy protection method based on ball tree (LP-BT). We first use the ball tree as a spatial index structure, and then do fuzzification on the location information of end users to obtain the maximum primary anonymous entropy, and combine the neural network learning algorithm to predict the corresponding entropy value. Finally, the final entropy is obtained based on the average entropy of the two stages.

By optimizing the robot programs and reducing idle time in robot operations, the amount of spent time can be reduced to minimize energy consumption of industrial robots. By using energy-efficient motors and drives, the amount of energy consumed by the robot can be reduced. Also, regular maintenance can reduce energy consumption of industrial robots by providing maximum efficiency for the robot's components. By implementing energy management systems, energy consumption of industrial robot can be monitored and analyzed to optimize energy consumption of industrial robot during working conditions. To minimize lost energy and reuse the energy usage during working times, regenerative braking can be used in the robots.
