Distance-Based Formation Tracking with Unknown Bounded Reference Velocities
This paper studies a leader-follower formation tracking problem where the
leaders are moving at the same unknown bounded velocity. A distance-based
control law is proposed for follower agents to maintain the desired distances
in the formation and move at the leaders' velocity. The control law consists of
a component to handle the uncertainty of the leaders' velocity and a component
to achieve the desired distances in finite time. Numerical simulations are also
provided to support the theoretical results.Comment: accepted to ICCAS 202
Some algorithms related to consistent decision table
Rough set theory is useful mathematical tool developed to deal with vagueness and uncertainty. As an important concept of rough set theory, an attribute reduct is a subset of attributes that are jointly sufficient and individually necessary for preserving a particular property of the given information table. Rough set theory is also the most popular for generating decision rules from decision table. In this paper, we propose an algorithm finding object reduct of consistent decsion table. On the other hand, we also show an algorithm to find some attribute reducts and the correctness of our algorithms is proof-theoretically. These our algorithms have polynomial time complexity. Our finding object reduct helps other algorithms of finding attribute reducts become more effectively, especially as working with huge consistent decision table
The impact of corporate social responsibility on the sustainable financial performance of Italian firms: mediating role of firm reputation
This research examines the impact of corporate social responsibility (CSR) dimensions (employee, customer, community, and environment) on the sustainable business performance of the
manufacturing industry. Manifestly, the mediating impact of firm
reputation is also analyzed between CSR and sustainable business
performance. In doing so, we have collected primary data from
Italian manufacturing firm’s employees using simple random sampling. Smart-PLS was used to test the reliability of the covariates
and relationships among the variables. The results revealed that
CSR has a positive association with firm reputation and sustainable business performance. The findings also indicated that firm
reputation has a significant and positive association with sustainable business performance. Moreover, firm’s reputation plays a
positive and significant mediating role between CSR and sustainable business performance. These results provide valuable
recommendations
Unveiling the Impact of Human Influence on Species Distributions in Vietnam: A Case Study Using Babblers (Aves: Timaliidae)
As developing countries give priority to economic growth, the effects of development threaten natural habitats and species distributions. Over the course of two decades, Vietnam has rapidly developed, especially in the expansion of agricultural production. However, no study has quantitatively measured the effects of recent human impact on the effects of past species distributions in Vietnam. We use locality data collected from multiple natural history collections, including several in Vietnam, to infer past species distributions. We assess habitat availability of five common babbler species (Aves: Timaliidae) using distribution models with data prior to rapid development that followed political reform. Overlaying the Global Human Influence Index with predicted distributions highlights the human impact on these distributions. Three important patterns emerge: (1) human impact influences common Timaliidae distributions similarly, (2) widespread species distributions show higher fragmentation due to human influence compared to narrowly distributed species in Vietnam, and (3) less than 20% of distributions overlap with nationally declared protected areas. We emphasize that conservation efforts should not only prioritize individual species, but also focus efforts on a regional scale, and that the use of museum data can be highly informative in conservation analyses. There are current obstacles to enforcing conservation of Vietnam’s already fragmented habitats, but our results suggest there is still time to reevaluate conservation approaches
STIRLING ENGINE: FROM DESIGN TO APPLICATION INTO PRACTICE AND EDUCATION
Stirling motor is a type of outside ignition heat motor that can utilize various fuel sources from customary structures (coal, oil, kindling, rice husk, and so forth) to sustainable power sources (sun-oriented energy), climate, squander heat usage, and so forth). The article centers around introducing the fundamental highlights of the improvement history, activity qualities, and plan techniques for certain sorts of Stirling motors, in this way offering useful appropriateness as well as a college preparing for understudies. The understudy studying Thermal Engineering in our nation today.

On how religions could accidentally incite lies and violence: folktales as a cultural transmitter
Folklore has a critical role as a cultural transmitter, all the while being a socially accepted medium for the expressions of culturally contradicting wishes and conducts. In this study of Vietnamese folktales, through the use of Bayesian multilevel modeling and the Markov chain Monte Carlo technique, we offer empirical evidence for how the interplay between religious teachings (Confucianism, Buddhism, and Taoism) and deviant behaviors (lying and violence) could affect a folktale’s outcome. The findings indicate that characters who lie and/or commit violent acts tend to have bad endings, as intuition would dictate, but when they are associated with any of the above Three Teachings, the final endings may vary. Positive outcomes are seen in cases where characters associated with Confucianism lie and characters associated with Buddhism act violently. The results supplement the worldwide literature on discrepancies between folklore and real-life conduct, as well as on the contradictory human behaviors vis-à -vis religious teachings. Overall, the study highlights the complexity of human decision-making, especially beyond the folklore realm
