Development of a computer model to predict platform station keeping requirements in the Gulf of Mexico using remote sensing data

Offshore operations such as oil drilling and radar monitoring require semisubmersible platforms to remain stationary at specific locations in the Gulf of Mexico. Ocean currents, wind, and waves in the Gulf of Mexico tend to move platforms away from their desired locations. A computer model was created to predict the station keeping requirements of a platform. The computer simulation uses remote sensing data from satellites and buoys as input. A background of the project, alternate approaches to the project, and the details of the simulation are presented

Base Foreign Words

As every computer programmer knows, numbers can be read in ways other than the decimal system we normally use. The decimal system is called to the base ten because it employs 10 digits: 0, 1, 2, ... , 9. But systems to different bases are also possible. Utopianists have proposed a duodecimal system using 12 digits because 12 is divisible by more factors (and hence mathematically handier) than 10. Computers use arithmetic to the base 2, because their circuitry admits of only two states -- on or off. Base 2 arithmetic employs only the digits 0 and 1

Cultural derivations of the Mosaic Code

Thesis (M.A.)--Boston University This item was digitized by the Internet Archive.The purpose of this study has been to determine upon what cultural sources the Hebrew lawmakers and prophets drew in their formulation of the Mosaic Code. To validate the choice of cultural sources selected for analysis the study first established the people of Israel as a distinct nation in the configuration of history, tracing its migrations up to that point in its development when it made its first legal covenant with God. In this way was determined the peoples with whom the Israelite nation made contact and with whose cultures they were to a greater or less degree impregnated

The number of independent sets in a graph with small maximum degree

Let ${\rm ind}(G)$ be the number of independent sets in a graph $G$. We show that if $G$ has maximum degree at most $5$ then $${\rm ind}(G) \leq 2^{{\rm iso}(G)} \prod_{uv \in E(G)} {\rm ind}(K_{d(u),d(v)})^{\frac{1}{d(u)d(v)}}$$ (where $d(\cdot)$ is vertex degree, ${\rm iso}(G)$ is the number of isolated vertices in $G$ and $K_{a,b}$ is the complete bipartite graph with $a$ vertices in one partition class and $b$ in the other), with equality if and only if each connected component of $G$ is either a complete bipartite graph or a single vertex. This bound (for all $G$) was conjectured by Kahn. A corollary of our result is that if $G$ is $d$-regular with $1 \leq d \leq 5$ then $${\rm ind}(G) \leq \left(2^{d+1}-1\right)^\frac{|V(G)|}{2d},$$ with equality if and only if $G$ is a disjoint union of $V(G)/2d$ copies of $K_{d,d}$. This bound (for all $d$) was conjectured by Alon and Kahn and recently proved for all $d$ by the second author, without the characterization of the extreme cases. Our proof involves a reduction to a finite search. For graphs with maximum degree at most $3$ the search could be done by hand, but for the case of maximum degree $4$ or $5$, a computer is needed.Comment: Article will appear in {\em Graphs and Combinatorics

The Value of Prior Professional Skills and Experiences: Perceptions of Second-Career Teachers

Second-career teachers’ pathways to teaching are often different from the traditional pathways of first-career teachers. This hermeneutic phenomenological study explored the common traits that second-career teachers share that may be unique within education, and whether second-career teachers’ prior skills and experiences assisted them in their new profession. The study also examined whether second-career teachers perceived that their certification programs helped them to develop their teacher identities and taught them to utilize their prior work experiences. Finally, this study investigated whether second career teachers believed that administrators valued their distinctive abilities. Data collection consisted of semi-structured interviews illustrating the individual experiences of 12 second-career teachers. Data were analyzed to develop emergent themes that provided answers to the four research questions guiding this study. The conclusions presented new insight into the high value second-career teachers place on their prior professional skills and experiences. Evidence also suggested that second-career teachers do not believe certification programs and district administrators place the same value on those skills and experiences. In order to reduce attrition of second-career teachers it is recommended that administrators recognize, develop, and utilize their prior professional skills and experiences as a resource for students and colleagues
