The EDM procedure is typically used to machining the Al6061 metal matrix composites with silicon carbide (SiC) with carbon nanotube reinforcement (CNT). The Metal Removal Rate (MRR), Surface Roughness (SR) as well as Tool Wear Rate (TWR) of the work piece material could potentially be measured using this method. Fundamental machining characteristics impacting the process's performance includingpulse ON time, discharge current as well as duty cycle were input attributes using Taguchi's parameter formulation. For each possible arrangement, a performance criterion has indeed been computed. The MRR, SR and TWR for every combination were computed in this investigation. The acquired outcomes have been tabulated. The research indicates that by employing grey relational analysis (GRA) to optimise the EDM parameters, improved MRR, TWR, and SR could be attained. MRR, TWR, and SR were 0.301 g/m m3, 0.003 g/mm3, and 4.03 m, respectively, according to the optimum outcomes of this research. © 2023 IEEE.

The problem of time-optimal planning of redundant robots is commonly solved with a decoupled two-stage approach. Starting from a task space path, at the first stage, the kinematic redundancy is locally optimized according to some performance index, then, at the second stage, the time-optimal parametrization of the resulting joint space path is performed. The performance indices to consider, as well as the redundancy resolution technique to adopt, impact the overall trajectory duration. First- or second-order Jacobian-based local redundancy resolution does not always guarantee satisfactory results at the second stage, in terms of trajectory duration, due to the choice of the initial positions, tuning of algorithm parameters, difficult joint limits management, non-convexity of the optimization problem. In this paper, we propose a global (or integral) approach for redundancy resolution, based on discrete dynamic programming, which further reduces the trajectory tracking time. To cope with the discretization of the redundancy space, the proposed methodology includes a post-processing optimization stage, aimed at smoothing the resulting joint space trajectory, guaranteeing technical feasibility. The approach is validated, in simulation, on a three-degrees-of-freedom planar robot executing two-dimensional tasks.

In the paper, a porous-Si/Si solar element with single- and double-layer anti-reflective coatings is simulated using PC1D simulation software. The reflection of eight monolayers (Si3N4, ZnO, ZnS, TiO2, SiO2, SiC, MgF2, Al2O3) and nine double-layered (SiO2/ZnS, MgF2/Si3N4, MgF2/SiO2 і SiO2/Al2O3, TiO2/SiO2, TiO2/Si3N4, TiO2/ZnO, SiO2/ZnS, MgF2/ZnS) anti-reflective coatings was studied. These are the most often used in the production of silicon solar elements. Optical propagation and absorption of photoconverters are considered using the transfer matrix method. The results showed that the best reflectance is observed for SiO2/ZnS, MgF2/Si3N4, MgF2/SiO2 і SiO2/Al2O3 double anti-reflective coatings, which were later used to model the photovoltaic parameters of porous-Si/Si solar cells. A decrease in the reflection of visible light indicates a better use of the incident solar radiation. The highest efficiency of 24.6% was achieved for devices on the base DLARC SiO2/ZnS. For DLARC MgF2/Si3N4, MgF2/SiO2 and SiO2/Al2O3 the efficiency was 24.1, 21.8 and 23.5%, respectively. In order to evaluate reflection losses due to texturing of the front surface, modeling of photoconverters with a pyramidal texture 3 μm deep with an angle of 0-89° was carried out. For the investigated DLARC/porous-Si/Si, the efficiency changed with an increase in the angle by 1.5-2.6%, taking the maximum value at angles of 85-87°. ©2024 IEEE.

The commercial future of organic photovoltaics (OPVs) relies on their efficiency and reliability. Recent progress in the field has ensured the achievement of device efficiency comparable to those of commercial silicon-based photovoltaics (Si-PVs) [1]. In pursuit of reliable devices, recent works have demonstrated the intrinsic stability of both small-molecule, vacuum deposited [2] and non-fullerene acceptor (NFA) - polymer-based devices [3] under controlled laboratory conditions. The final step for outdoor deployment is therefore a demonstration of the reliability of large area OPV modules in the field, subjected to fluctuating environmental conditions such as humidity, temperature, rainfall, snow, and solar intensity. In this work, we develop a customized test facility intended for the study of the reliability of large area OPV modules deployed in outdoor environments. The facility is designed for automated in-situ measurements calibrated to 1 sun solar intensity, AM 1.5 G illumination. Initial data show the modules retain more than 95% of their initial performance for 150 h when exposed to varying solar intensities, temperature fluctuations of -2°C to 10°C, and relative humidity as high as 90%. The only significant extrinsic challenge to device stability observed was the ingress of water into the package. This is mitigated by improved packaging which utilizes polyisobutylene (PIB) encapsulation and a customized insulated glass unit (IGU). © 2024 IEEE.

Optimal Actuator Location for Diffusion Equation with Neumann Boundary Control

This paper is concerned with optimal actuator location for a class of diffusion equations with boundary control. The problem of optimal actuator location based on a linear quadratic cost in case of the worst initial condition is formulated. This leads to a cost involving the operator norm of the Riccati operator. The existence of optimal locations within the uniform operator norm is guaranteed. A Galerkin-based algorithm for approximating the optimal locations, and the convergence of the approximation of the optimal locations is also presented.

Nowadays, a large number of AI-powered healthcare cyber-physical systems (CPSs) have been used in healthcare services. In order to provide better care, AI-powered healthcare CPSs analyze the data they collect using a variety of techniques. Data analysis for artificial intelligence (AI)-driven healthcare CPS is one of these approaches. However, none of the techniques in data analysis can provide a good representation of contiguous and negative information. Therefore, we are the first to introduce the problem of contiguous negative sequential pattern mining. A novel algorithm called Contiguous Negative Sequential Pattern Miner (CNSPM) is proposed to discover and analyze contiguous negative sequential patterns (CNSPs) from the data collected by healthcare CPSs. Finally, we select some real medical and non-medical datasets to conduct numerous experiments. We further analyze the discovered patterns and show how healthcare services can use meaningful patterns for medical decision-making. The performance results on these datasets demonstrate that the proposed algorithm can discover more valuable patterns efficiently and effectively from the collected and transformed medical data. © 2013 IEEE.

Generative models has been widely used for symbolic music generation. However, the quality of the music produced is hindered by the inadequate modeling of the harmonic and rhythmic relationships among various instruments, as well as the neglect of musical principles. To address the aforementioned challenges, we propose an attention-based hybrid learning multitrack music generation(HL-MTMG) model that incorporates regularization of musical rules and simultaneous exploitation between intra-track and inter-track information, resulting in the generation of high-quality symbolic music that conforms to established musical principles. Through extensive examinations of musical structures, specifically rhythm, and assessments by domain experts, our study demonstrates that HL-MTMG exhibits significant improvements in musical integrity and fluency in comparison to symbolic music generation models, such as, MuseGAN and HRNN. © 2023 IEEE.

People resonate more with music when exposed to visual information, and music enhances their perception of video content. Cross-modal recommendation techniques can be used to suggest appropriate background music for a given video. However, there is not a simple correspondence between the different modal data. Therefore, to explore the association between the two modalities of video and music, we propose MFF-VBMR, a video background music recommendation model based on multi-level fusion features. The model uses the cross-modal information of static, dynamic and emotional content of video and music to realize the task of matching and recommending suitable background music for a given video. Experimental results show that the proposed model outperforms other existing models in terms of performance and achieves satisfactory results for video background music recommendation. © 2023 IEEE.
