The performance of several adversarial search algorithms is very dependent on the move generation and ordering procedure, as well as on the transposition table characteristics. In this work we compare Alpha-beta, MTD-f and NegaScout performance in the presence and absence of the following features: transposition table, Hash Move heuristic and move ordering using the evaluation function. We found that NegaScout did not yield major improvements over Alpha-Beta, which is likely due to the move ordering performed using a weak evaluation function. In most cases, MTD-f examines fewer nodes, and completes fixed depth searches in less time than Alpha-beta and NegaScout. This is consistent with the literature when using coarse grained evaluation functions. Finally, we found that enabling move ordering leads to fewer nodes examined than enabling the Hash Move heuristic, but, as sorting is time consuming, search is slower. Best results overall are found using MTD-f with all enhancements enabled. These results, in a previously unexplored game, are consistent with existing literature. This enables us to make predictions of algorithm and heuristics' performance in novel games, based on an analysis of the games' features, without having to implement all techniques. © 2022 IEEE.

• We need to develop a framework for tracking progress towards alignment with a circular economy for the life cycles of solar PV and lithium-ion batteries - as well as other products. • This framework needs to be explicitly grounded in circular economy strategies, but also produce information that is relevant for decision makers involved in battery or solar PV life cycles. • To achieve this, challenges regarding data and assessment needs, as well as barriers for translation to decision-relevant information, need to be overcome. © Advanced Power and Energy program 2022.

A planing hull high-speed ferry with a stepped hull becomes a well-liked mode of water transportation for archipelago countries. On the other hand, the shape of steps on the bottom hull has not been recently taken into explicit consideration regarding the speed requirement and hydrodynamic properties. In this study, the step W shapes, were adopted to find the improved hydrodynamic performance in the planing conditions. To provide a more precise prediction of the pressure, velocity fields, and void fraction, the CFD was applied the Finite Volume Method (FVM) and coupled with Volume of Fluid Method (VOF) to capture air cavity The numerical conditions of the planing hull were trimmed by the stern with 2, and 3 degrees. This study discussed the air cavity that occurred behind the stepped area that can affect the hydrodynamic behaviour. © 2023 by the International Society of Offshore and Polar Engineers (ISOPE).

Despite the potential benefits that the integration of distributed energy resources (DERs) can bring to the system, it may cause problems related to power quality constraints, such $as$ reverse power flow in substation and overvoltages. An effective approach to address these problems involves the adoption of reactive and active power control in grid-tie inverters associated with DER. Therefore, this paper assesses the impacts of grid-tie inverter control modes, including both Volt-Var and Volt-Watt strategies, on the DER hosting capacity. In order to improve the overall system operation, modifications in the Volt-Var and Volt-Watt curves were proposed. It is noteworthy that these control strategies can have adverse effects on certain distribution system performance indicators, such $as$ voltage deviation and power losses;for this reason, these indicators are also evaluated in this study. A stochastic approach was adopted to deal with the uncertainties associated with DERs and loads. Finally, from tests conducted in the IEEE 33-bus test system, it was concluded that the proper adjustment of the Volt-Var and Volt-Watt control curves significantly influences DER hosting capacity, $as$ well $as$ voltage deviation and power losses. © 2023 IEEE.

Current work environments have undergone a noticeable shift towards higher cognitive demands and increased involvement in multitask performance. It has therefore become crucial to investigate the levels of mental workload experienced by operators. Simulated cognitive multitasking, with varying workload intensity, duration and work order, was tested in 18 volunteers to determine its impact on task performance, perceived workload, galvanic skin response;GSR, and cortisol levels in sweat and saliva. The results showed that as workload intensity increased, there was a concurrent increase in perceived workload and a significant negative impact on task performance. As time progressed, there was a notable increase in performance. Differences in GSR can be observed based on time on task and order of stressor levels delivered to the participants. Preliminary results of cortisol levels in sweat and saliva showed distinct trends in relation to workload intensity. © 2023 IEEE.

Controller tuning with multi-objective optimization: benchmark definitions for SISO linear systems: A PI controller case ⁎

引用

IFAC-PapersOnLine 2024年第7期58卷 126-131页

Multi-objective optimization techniques are practical techniques for controller tuning purposes. A wide variety of papers use such an approach or propose new algorithms to approximate the Pareto front. Nevertheless, despite the expressive volume of works dealing with it, there is no standard benchmark testbed that could be used as a baseline comparison among different techniques. This work addresses such a gap, with a first step proposing a linear-SISO testbed with guidelines and rules and providing a basic example for a PI controller. Such a benchmark is expected to promote further research on the topic.

The aerospace manufacturing industry exhibits significant complexity in all its tasks. For instance, the aircraft’s main body comprises several components with multiple dimensions, geometries, and materials. This kind of manufacturing system is specialised in creating aerospace parts characterised by advanced technology, limited production quantities, and a high degree of customisation. The aerospace products and the corresponding manufacturing systems have extensive life cycles spanning decades and are repurposed to accommodate product variations. Any disturbance during the project progression has the potential to result in escalated expenses and time investments, leaving economic and environmental drivers. In this way, Cyber-Physical Production systems (CPPS) are emerging to reduce misinterpretation and mistakes across all stages of the manufacturing process. Therefore, the main aim of this paper is to discuss the current issues and emergent technologies across the literature review to address the following Research Issue 1 (RI1): What are the current issues and emergent technologies in CPPS and KDD for the Aerospace Industry? Research Issue 2 (RI2): What is the gap in CPPS and KDD for the aerospace industry? This initial literature review is concentrated on the Knowledge data-driven (KDD) to aid in developing CPPS for Aerospace Sheet Metal (ASM) parts manufacturing and examining the use of CPPS in the aerospace sector. Finally, this research contributes to the research community with an initial overview of research trends in the domain of KDD for CPPS in the aerospace industry and finds the main research gaps in this area.

Knowing if a Sokoban level has a solution requires a high investment of computational resources. This also happens when estimating difficulty; heuristics may not be precise, only work for simplified cases, be discontinuous and take much computing time. The calculation of high-fidelity heuristics is expensive and the performance of optimization systems is reduced by the time they take to deliver the result. In this article, two Convolutional Neural Networks (CNN) are implemented, a classifier of resolvable Sokoban boards and a regressor that predicts the number of pushes necessary to solve them. These obtained an accuracy of 79 % and MAE of 28, respectively. Trained models are useful in systems that do not require optimality, but rather guidance within the search space that balances time and quality. These networks can be used as surrogate methods, replacing high-fidelity heuristics that take too long.
