Path Planning Of Coal Mine Rescue Robot Based On Improved A* Algorithm, Zhang Weimin, Zhang Yue, Zhang Hui Dec 2022

Path Planning Of Coal Mine Rescue Robot Based On Improved A* Algorithm, Zhang Weimin, Zhang Yue, Zhang Hui

Coal Geology & Exploration

A coal mine rescue robot that performs a rescue task needs to obtain the environment model and plan a collision-free path from the current location to the target location with the built-in algorithm upon receiving a task instruction. In order to reduce the moving time of the rescue robot, the path is usually required to be time-optimal. However, the path planned by the conventional A* algorithm that is widely used at present under the grid map environment has many problems, such as many path redundancy points and large turning angle, which leads to the fact that the path is suboptimal …

The Early College Research Tradition And The People Who Made It: A History Of Interventions That Shaped The Field, Russ Olwell

Early College Folio

Early college as an educational reform has had a unique trajectory over the past two decades. School reform in the United States (with a few exceptions) has been a top-down movement, and the majority of attention has centered on grades three through eight, the grade levels the No Child Left Behind Act focused on. Early college, by contrast, has been a grassroots movement in many areas and has focused on high school students and their aspirations for college. This article describes the story of early college through the lens of individuals whose research helped to reorient the field and broaden …

Elements Of Fantasy In The Presentation Of Environmental Problems In Prapt’S Nirat Mahannop, Saifon Sianglee, Sirichaya Corngreat Dec 2022

Elements Of Fantasy In The Presentation Of Environmental Problems In Prapt’S Nirat Mahannop, Saifon Sianglee, Sirichaya Corngreat

Journal of Letters

This research examines the character “Moen” from Prapt’s detective novel “Nirat Mahannop” with reference to the concept of ecological conscience. Results show that Prapt deploys elements of fantasy to express Moen’s supernatural appearance and vocal power. This positions Moen as a voice on Thailand’s environmental problems from 2013 to 2015, relating to the oil spill that affected the country’s marine environment. Apart from that, Moen reflects powerful relationships between humans and the environment, capitalism and nature, in conjunction with the image of humans as an environmental threat.

“Superior Honor And Dignity” : A Critical Discourse Analysis Of The Relationship Between Linguistic Strategies And Ideologies In The Automobile Business, Siravast Kavilanan Dec 2022

“Superior Honor And Dignity” : A Critical Discourse Analysis Of The Relationship Between Linguistic Strategies And Ideologies In The Automobile Business, Siravast Kavilanan

Journal of Letters

This article examines the relationship between linguistic strategies and ideologies of superior honor and dignity in the automobile business. These relationships are identified using critical discourse analysis based on the three-dimensional framework of Fairclough (1995). Results show that the linguistic strategies used to construct these ideologies include lexical selection, presupposition, negation, claiming and reference. This discourse also indicates that while consumers may recognize the importance of cars, as an automobile business, profits are also important. As a result, automobile companies have constructed discourses to manipulate people to recognize that cars are not just vehicles, but indicators of social status that …

Making Group Work Work: Constructing Groups And Assignments Based Around Relevant Assessments To Increase Student Success, James Altman

UNLV Best Teaching Practices Expo

Helping college students get the most out of their talents, is challenging even without the ongoing uncertainty of the post-Pandemic landscape. Shyness, lack of comfort with the subject matter, and fear of having their ideas dismissed, can all keep students from expressing their ideas as fully as they, and we, would like. This can lead to non-completion or plagiarism of assignments. In group settings, it can lead to one student “taking over” the project, or the rest of the group “pushing it off” on one member. Constructing groups and/or assignments based around relevant assessments, namely Myers-Briggs and “The Six Working …
