An Eolian Dust Origin For Clastic Fines Of Devono-Mississippian Mudrocks Of The Greater North American Midcontinent, Austin J. Mcglannan, Alicia Bonar, Lily Pfeifer, Sebastian Steinig, Paul Valdes, Steven Adams, David Duarte, Benmadi Milad, Andrew Cullen, Gerilyn S. Soreghan

School of Earth & Environment Departmental Research

Upper Devonian and Lower–Middle Mississippian strata of the North American midcontinent are ubiquitously fine-grained and silt-rich, comprising both so-called shale as well as argillaceous limestone (or calcareous siltstone) that accumulated in the Laurentian epeiric sea. Although long recognized as recording marine deposition, the origin and transport of the fine-grained siliciclastic material in these units remains enigmatic because they do not connect to any proximal deltaic feeder systems. Here, we present new data on grain size, whole-rock geochemistry, mineralogy, and U-Pb detrital-zircon geochronology from units across Oklahoma; we then integrate these data with models of surface wind circulation, refined paleogeographic reconstructions, …

Randomized Algorithms For Resource Allocation In Device To Device Communication., Subhankar Ghosal Dr.

Doctoral Theses

In device to device (D2D) communication, two users residing in close proximity can directly communicate between them, through a common channel, without the need of a base station. A pair of D2D users forms a link and a channel needs to be allocated to it. The interference relationship among the active links at time t is modelled as an interference graph g(t). To establish interference-free communication, we have to assign a channel vector C(t) and a power vector corresponding to the active links such that the required signal to interference plus noise ratio (SINR) is satisfied for each link. Since …

Socio-Cultural Status Of Albinism In Africa: Challenging Myths, Concepts, And Stereotypes, Raita Steyn

Journal of Global Awareness

This article analyses the socio-cultural status of Albinism in Africa and the role unchallenged stereotypes, irrational concepts, and unfounded beliefs play in the lives of persons with albinism. Following some beliefs, persons with albinism” do not die but vanish” to later “return as ghosts to haunt the living.” The author discusses this paradox about persons with albinism identified as hunted victims and simultaneously haunting perpetrators. The research examines the concept of albinism being a curse from dead ancestors or theodicy and its association with supernatural powers. By a comparative and diachronic approach, the study challenges unsubstantiated stereotypes. This study aims …

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 …

“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 …

Over-Policing And Under-Protecting In American Cities, Margaret Hession

Honors Program Theses and Projects

In recent years there have been numerous protests all over the United States focused on the over-policing of African Americans by law enforcement. Those involved are protesting against a term known as over-policing, the blatant brutality and senseless murders, that have taken place for decades but have been made ever more visible by our modern media channels. “Over-policing allows police to use excessive force and brutalize disenfranchised neighborhoods and target people of color indiscriminately. Ironically, as politicians take a “tough on crime” stance, violence has actually gone down, but police budgets and presence have increased. The American criminal justice system …
