A Comparison Of Combined Overlap Block Fuzzy Cognitive Maps (Cobfcm) And Combined Overlap Block Neutrosophic Cognitive Map (Cobncm) In Finding The Hidden Patterns And Indeterminacies In Psychological Causal Models: Case Study Of Adhd, Hojjatollah Farahani, Florentin Smarandache, Lihshing Leigh Wang

Branch Mathematics and Statistics Faculty and Staff Publications

In spite of researchers’ concerns to find causalities, reviewing the literature of psychological studies one may argue that the classical statistical methods applied in order to find causalities are unable to find uncertainty and indeterminacies of the relationships between concepts.

In this paper, we introduce two methods to find effective solutions by identifying “hidden” patterns in the patients’ cognitive maps. Combined Overlap Block Fuzzy Cognitive Map (COBFCM) and Combined Overlap Block Neutrosophic Map (COBNCM) are effective when the number of concepts can be grouped and are large in numbers. In the first section, we introduce COBFCM, COBNCM, their applications, and …

Engineering Faculty Perspectives On The Nature Of Quality Teaching, Jacqueline C. Mcneil, Matthew W. Ohland

Faculty and Staff Scholarship

There is wide agreement that teaching quality matters in higher education, but faculty have varied ideas about the definition of quality. Faculty definitions of quality teaching were coded using an existing framework. The most common definition of teaching quality (held by 49% of participants) is associated with elitism and restricted access—the best way to improve education is to admit better students. These faculty focus on education as “knowledge transfer” and “learning content.” Another 38% of faculty had a transformational perspective, more focused on process than content, valuing “empowering students,” “developing students,” and “creating an environment for learning.” These faculty refer …

Computational Fluid Dynamics Analysis Of An Ideal Anguilliform Swimming Motion, Charles Rogers

LSU New Orleans Theses and Dissertations

There is an ongoing interest in analyzing the flow characteristics of swimming fish. Biology has resulted in some very efficient motions and formulating these motions is of interest to engineers. One such theory was written by Dr. William Vorus and Dr. Brandon Taravella involving ideal efficiency. It is therefore interesting to test the calculations to see if it is possible to design a motion that can create thrust without necessarily creating vorticity. The computational fluid dynamics software of ANSYS Fluent was used to calculate the resulting flow field of the eel motion to compare with the theoretical values.

Shock Pulse Filtering Evaluation On Package Size And Cost, Matthew P. Daum Ph.D.

Journal of Applied Packaging Research

Distribution packaging design often relies on cushion curves to determine required material thickness needed for product protection during shipment. The material thickness chosen based on cushion curves establishes overall package size, a key determiner of logistics costs. Cushion curves are constructed by dropping a mass onto a cushion, and interpreting the resulting shock pulse deceleration. The reported deceleration can be highly influenced by applying a “filter” to the shock pulse, a useful standar d prac - tice that removes unwanted high frequency elements superimposed on top of the basic shock pulse shape. Standard test methods for generating cushion curves generally …
