Adaptive multi-criteria decision making for electric vehicles: a hybrid approach based on RANCOM and ESP-SPOTIS

In today’s globalized technological area, aligning decisions with customer preferences is crucial yet challenging due to the complexities and uncertainties involved. Multi-Criteria Decision Analysis (MCDA) serves as a vital tool for constructing support systems that cater to customer-centric trends. While existing MCDA methods vary in their calculation concepts, some prioritize ideal solutions, while others accommodate personalized preferences within dynamic decision contexts. Moreover, determining the relevance of criteria based on expert knowledge adds another layer of personalization to the evaluation process, further individualizing decision-making. However, current decision models often fail to integrate these concepts, leaving a gap in how recommendations can be enhanced when both are combined. To address these challenges, this paper introduces an innovative approach integrating Ranking Comparison and Expected Solution Point Stable Preference Ordering Towards Ideal Solution methods. This hybrid model incorporates personalization into multi-criteria evaluation, catering to individual preferences. By representing customer preferences through two distinct measures, the proposed approach ensures personalized recommendations aligned with decision-makers’ needs. The efficacy of the hybrid model was validated through its application to the electric vehicle selection problem. The verification process highlighted potential disparities compared to other multi-criteria approaches, establishing a consumer preference-based Decision Support System approach for more precise and personalized selection recommendations.

Impact of UV-C irradiation on pests and fungi in stored wheat

The application of UVC radiation in stored wheat grains in Brazil is still very recent and the study of the parameters of this technology in stored products becomes important for the advancement in the scientific as well as technological areas. This is mainly due to the fact that it is a cheap technology that does not leave residues, and can be used to replace chemical pesticides. Thus, the objective of the present work is to evaluate the effect of UV-C radiation on the control of insect pests and fungi in wheat grains. For this purpose, wheat grains containing 20 adult insects of Sitophilus sp were irradiated with UVC light for 15 and 30 minutes at intervals of 15 days for 120 days of storage. At the end of the period, live and dead insects, mass loss and total fungal count were evaluated. Based on the analyses carried out, the use of UV-C Light has been reaffirmed as an effective microbiological control method. On the other hand, the study of its use as a method of biological control, under the conditions of the experiment in which the plant material used were wheat grains with moisture content below 10%, is not feasible since the exposure of wheat grains infested with Sitophilus sp. During the 15 and 30 minute periods, every 15 days there was no statistical difference when compared to the control group.

Innovation governance in Poland. Technological trends with an outlook to 2030

Ultimate-scaled one-dimensional transistors: Surpassing the subthreshold swing limit

The continuous miniaturization of field-effect transistors (FETs) has propelled microprocessors to unprecedented levels of integration. However, further scaling encounters a critical trade-off between integration density and power efficiency. To transcend this limitation, a new class of steep-slope transistors has emerged, capable of surpassing the subthreshold swing (SS) limit but imposing stringent requirements on gate electrostatics. In this Perspective, we propose atomically-thin, one-dimensional (1D) materials as promising candidates for steep-slope switches. These materials offer distinct advantages in electrostatic integrity, crucial for overcoming traditional scaling bottlenecks. We delve into the underlying operational mechanisms to elucidate design methodologies and optimization strategies for 1D steep-slope transistors. We anticipate that by engineering the density of states distribution and carrier injection mechanisms, these transistors will achieve unparalleled performance and energy efficiency, representing a new frontier in device scaling. Our insights seek to facilitate future research and development in this transformative area of semiconductor technology.

Proton Transfer Kinetics at a Defect-Free Liquid-Liquid Interface

Proton transfer at electrochemical interfaces is fundamentally important for many areas of science and technology, yet kinetic measurements of this elementary step are often convoluted by inhomogeneous electrode surface structures. We show that facilitated proton transfer at the interface between two immiscible electrolyte solutions (ITIES) can serve as a model system to study proton transfer kinetics in the absence of defects found at solid|electrolyte interfaces. Diffusion-controlled micropipette voltammetry revealed that 2,6-diphenylpyridine (DPP) facilitated direct proton transfer across the liquid|liquid interface and voltammetry at nanopipette-supported interfaces yielded activation-controlled ion transfer currents. The exchange current density for proton transfer at the ITIES is comparable to exchange current densities recently reported for H-UPD on Pt (111) and provides the first direct means of comparing ion transfer kinetics between solid|liquid and liquid|liquid interfaces, supporting the development of a general theory of ion transfer kinetics.

The Activation of Magnesium Sintering by Zinc Addition

Light alloys based on magnesium are widely used in most areas of science and technology. However, magnesium powder alloys are quite difficult to sinter due to the stable film of oxides that counteracts diffusion. Therefore, finding a method to activate magnesium sintering is urgent. This study examines the effect of adding 5 wt. % and 10 wt. % zinc to the sintering pattern of magnesium powders at 430 °C; a dwell of 30 min was used to homogenize at the densification’s temperature. Scanning electron microscopy (SEM) was used to characterize the alloy’s microstructure, while the phase composition was characterized using X-ray diffraction (XRD) and energy dispersion spectroscopy (EDS). The sintering densities of Mg–5Zn and Mg–10Zn were found to be 88% and 92%, respectively. The results show that after sintering, a heterophase structure of the alloy is formed based on a solid solution and phases MgZn and Mg50Zn21. To establish the sintering mechanism, the interaction at the MgO and Zn melt phase interface was analyzed using the sessile drop method. The minimum contact angle—65°—was discovered at 500 °C with a 20 min holding time. It was demonstrated that the sintering process in the Mg–Zn system proceeds through the following stages: (1) penetration of zinc into oxide-free surfaces; (2) crystallization of a solid solution, intermetallics; and (3) the removal of magnesium oxide from the particle surface, with oxide particles deposited on the surface of the sample.

Underground logistics systems (ULS) are gaining traction due to their effective utilization of this space to enhance urban spatial efficiency. However, research on technological advancements in related fields remains limited. To address this gap, we applied a data-driven approach using patent data related to the ULS to develop a technology roadmap for the field. We employed Latent Dirichlet Allocation (LDA), a machine learning-based topic modeling technique, to categorize and identify six specific technology areas within the ULS domain. Subsequently, we conducted portfolio analytics to pinpoint technology areas with high technological value and to identify the major patent applicants in these areas. Finally, we assessed the technology market potential by mapping the technology life cycle for the identified high-value areas. Among the six technology areas identified, Topic 1 (Underground Material Handling System) and Topic 4 (Underground Transportation System) showed significant patent activity from companies and research institutions in China, the United States, South Korea, and Germany compared to other countries. These areas have the top 10 patent applicants, accounting for 20.8% and 13.6% of all patent applications, respectively. Additionally, technology life cycle analytics revealed a growth trajectory for these identified areas, indicating their rapid expansion and high innovation potential. This study provides a data-driven methodology to develop a technology roadmap that offers valuable insights for researchers, engineers, and policymakers in the ULS industry and supports informed decision-making regarding the field’s future direction.
