In this study, we propose a novel intelligent neural guidance law by applying several neural network optimization algorithms alternatively in each step, such as Gradient descent (Gd), Levenberg-Marquardt (LM) and Scaled Conjugate Gradient (SCG) methods. The missile turning rate time constant, radome slope error, initial heading error and the noise effects in the guidance loop (such as target maneuver, glint, and fading noises) are taken into consideration by using the adjoint simulation technique. Comparisons with the traditional proportional navigation (PN) method and those applying only one optimization algorithm for the cases of lower and higher altitudes are also made; note that the miss distances obtained by the proposed neural guidance law are always lower.

Amidst the rapidly evolving global economic landscape, the BRICS nations (Brazil, Russia, India, China, and South Africa) have emerged as pivotal players, particularly in the construction sector, which serves as a cornerstone for their continued growth and development. This sector’s performance not only reflects the economic health of these nations but also their capacity for sustainable urban and infrastructural expansion. This study aims to provide a comprehensive evaluative analysis of the construction industry’s efficiency across the BRICS nations using the Bounded Rationality data Envelopment Analysis (BR-dEA) model, incorporating principles from Prospect Theory. Moreover, this study also investigates the relationship between behavioral economics and operational efficiency within this sector. According to well-known prospect theory, the psychological behavioral coefficients applied in the model include the loss aversion, the gain preference, the gain curvature, and the loss curvature coefficients. Key performance indicators for the model were meticulously chosen, normalized, and derived from reputable global and national databases. The findings revealed that efficiency scores generally increased with higher gain preference coefficients across different loss aversion settings, indicating that valuing gains more positively is associated with greater efficiency. Variations were observed among the BRICS countries, suggesting that efficiency is influenced by country-specific behavioral factors. This study contributes to the literature by integrating behavioral economics into efficiency analysis and offers practical insights for policymakers and industry leaders within the BRICS nations. Limitations are acknowledged, primarily relating to data availability and the inherent complexities of behavioral modeling, which provide avenues for future research to expand upon these initial findings.

The dispatching of labor and distribution of tasks among workers are important aspects of corporate operations. Labor dispatch refers to the dispatching of employees to meet with clients;however, dispatches commonly vary with time. This means that any analysis pertaining to labor dispatch and work distribution should also vary with time. In this study, MATLAB was used to analyze data from anonymous caseworkers in central Taiwan in order to identify relationships between the location of their offices and the homes of their clients. Our aim was to determine the rationality behind labor dispatch and work distribution. This led us to develop a novel method by which to dispatch labor in order to achieve a more equitable distribution of work. Simulations demonstrate the efficacy of the proposed scheme in improving labor dispatch and work distribution. © 2017 IEEE.

Most audio source separation-related studies have been speech/singing separation, and those on musical instruments separation have been relatively scant. In this research, a stacked recurrent neural network was used to train a model to extract electric guitar sound from mixtures of electric guitar and other musical instruments. Objective assessment scores indicate that the proposed method can extract the electric guitar sounds from the musical mixtures successfully.

developing cost-effective ph.toelectrodes with a low band gap in the NIR-visible regions remains a challenge to achieve effective hydrogen production. We report the details of superstrate-configured ph.tocathodes, consisting of antimony selenide (Sb2Se3) light absorbing layers with titanium dioxide (TiO2) as a hole transport layer, exhibiting the capability for hydrogen evolution with broad range light absorption enabled by the low band gap value of ∼1.2 eV of Sb2Se3. Strong anisotropy is a significant characteristic property of Sb2Se3, allowing superior electrical transportation along the [hkl] crystallograph.c orientation, which is obtained via close space evaporation of presynthesized bulk material at a growth temperature of 250 °C, over the solution-processed TiO2 film on a fluorine-doped tin oxide (FTO) substrate. The superstrate-configured FTO/TiO2/Sb2Se3 ph.tocathode exhibited a ph.tocurrent density of 100 μA cm-2 at −0.3 V vs RHE in 0.5 M H2SO4 under 1 sun illumination. To further improve ph.tocurrent density, Pt as a cocatalyst was deposited over Sb2Se3 that led to enhanced ph.tocurrent to 3 mA cm-2 at −0.3 V vs RHE in 0.5 M H2SO4 under 1 sun illumination. despite the relatively lower ph.tocurrent observed, which resulted due to a large conduction band offset (ΔECB = 0.99 eV) of the TiO2/Sb2Se3 interface in a superstrate configuration, a significantly lower onset potential of −0.1 V vs RHE was observed. The results are encouraging due to the low band gap of Sb2Se3, ph.tocorrosion stability, and straightforward fabrication, which is expected to assist for significant outcomes. © 2024 American Chemical Society.

This research aims to create a virtual reality-based practice system that simulates real-stage performance environments, assisting amateur dancers in overcoming stage fright and practicing group choreograph. that is difficult to achieve during individual practice. In this study, users can engage in performance simulations within the created system using the HTC VIVE virtual reality device. Within the system, we have developed a virtual stage space system that only requires a 2m x 3.5m ph.sical area to simulate a large virtual stage experience. Users can also simulate choreograph.c positioning with virtual dance partners within this system, providing amateur dancers with group dance rehearsal practice opportunities that are not feasible during solo practice. Additionally, by creating three different audience modes, we aim to help users simulate various audience scenarios they may encounter during a performance. The system includes a recording feature that captures users' simulated performances, allowing them to review their actions and receive feedback after practice. © 2024 IEEE.

In this research, we proposed a guidance law by refining the fuzzy membership functions and applying neural optimization algorithms alternatively in each step, such as Gradient descent (Gd) and Levenberg-Marquardt (LM) methods. The boundaries of fuzzy error membership functions are lowered to increase the system performance. Besides, the error rate and output are divided into six types of models for trade-off. Both missile turning rate time constant and radome aberration error slope are taken into consideration. Comparisons with the proportion navigation (PN), fuzzy and the proposed methods are also made; we note the performances obtained by the proposed method are better. Besides, the acceleration commands are lower than the previous research and without oscillation or diverging effects at the final stage of interception. Thus even there are system parameter variation effects; the guidance loops can always track the target, and yields better guidance performances.

In this paper we present results of a series of experiments in which combinations of vector quantization and temporal energy contours are incorporated into the standard framework for the word recognizer. We consider two distinct word vocabularies, namely, a set of 10 digits, and a 129-word airlines vocabulary. We show that the incorporation of energy leads to small but consistent improvements in performance for the digits vocabulary; the incorporation of vector quantization (in a judicious manner) leads to small degradation in performance for both vocabularies, but at the same time reduces overall computation of the recognizer by a significant amount. We conclude that a high-performance, moderate-computation, isolated word recognizer can be achieved using vector quantization and the temporal energy contour.

With increasing dependence on precision electronic equipment, self-protection is becoming essential. The protection circuits commonly used before were fuses and circuit breakers which, however, they are not enough for the current need of high-speed protection circuits and automated engineering logic. In this paper, we develop a new ultrahigh-speed protection circuit, which is over exceeded 20 times faster than traditional circuits and has the ability to self-recover when any failure occurs. With the new circuit developed, it is not necessary to do manual restart and will meet the future needs of protection for electronic precision equipment. This design provides greater convenience and reliability for the unmanned equipment for the future. © 2019 IEEE.

Students’ computational thinking and programming skills may grow due to collaborative programming. But as the researchers have noted, students frequently do not use metacognition to manage their cognitive activities while collaborating, which negatively affects learning. This study created a metacognition-based collaborative programming (MCP) system to improve students’ performance in collaborative programming. A seven-week study examined how the approach affected students’ performance in programming courses. The 88 middle school students were split into two groups: the experimental group received the metacognition-based collaborative programming approach, and the control group received the conventional computer-supported collaborative programming approach. The results indicated that the metacognitive-based collaborative programming approach enhanced students’ academic scores in programming courses and their computational thinking tendencies. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
