When communicating across a channel, it is inevitable that such pathways of communication be “noisy”, thus there is always some sort of interference across the channel. This results in messages not always being received as they were sent. In order to solve these problems, coding theory developed and is used both to detect and correct errors. It is used for data compression, error correction, cryptography and network coding. In error correction, a concentration on algebraic coding theory lies with linear codes, including cyclic and constacyclic codes. In this poster presentation, we will discuss the history of coding theory, going in depth with cyclic and constacyclic codes, as well as discussing applications and current problems being resolved using algebraic coding theory.
Service learning is a meaningful way to combine classroom instruction with community service. By applying course content to community activities, service learning projects engage students with the community and heighten public awareness of the subject matter. Advantages of service learning projects reach four populations: benefiting not only the student, faculty, and university but members of the local community as well. General Chemistry Laboratory students from KSU Trumbull Campus recently partnered with Book Buddies at the Warren-Trumbull County Public Library to include a science literature night. For this special event, children (grades 1-4) selected from a list of science themed books to read with their assigned tutor and then subsequently participated in hands-on science experiments highlighting topics presented in the books. KSU Trumbull chemistry students designed all of the safe, fun, and entertaining experiments to excite young children and foster a positive learning experience with science.
Discovering the Bedrock and Glacial Geologic History of Pymatuning Lake State Park, Ashtabula County, Ohio04/06/2016
Pymatuning Lake State Park is located on the wetlands surrounding the Shenango River in Ashtabula County, Ohio and Crawford County, Pennsylvania. In 1933, the Pymatuning Lake Reservoir was completed on the river for flood control, water supply, recreation, and fish and wildlife management. In addition to the dam, the Espyville-Andover Highway was completed to cross the lake. However, detailed geologic information of the park is lacking for the public to understand its ancient history. A detailed investigation was conducted to better constrain the geologic history of Pymatuning Lake State Park.
Detailed information of the park was gathered through extensive fieldwork and published data. Bedrock and glacial geologic maps were constructed this data. Thickness of glacial material and bedrock formations were determined using ground water well data. A cross section through the park was produced, showing the geology in the third dimension.
Pymatuning Lake State Park is situated on the glaciated plateau of northeastern Ohio and northwestern Pennsylvania border where Pleistocene glaciers advanced over the gentle hills and stream valleys of the land formerly uplifted as part of the Appalachian Mountain building process. The subsurface bedrock units in the park consist of Devonian shales. The bedrock was covered by several ice advances of the Wisconsinan Glacier that left behind glacial features consisting of the Hiram, Lavery, and Kent ground moraines, and the Defiance end moraine north of the park. These glacial units completely cover the bedrock, leaving minimum exposures in the area.
