Do you know how important GIS is to the transportation industry? The spatial applications to this field are so extensive that they represent an entire sub-discipline within the GIS community. In this course, we'll learn about the primary modes of transportation and explore some of the spatial applications developed to meet the unique needs of each. We'll also take a close look at some key organizations in the industry and learn firsthand from more than a dozen transportation professionals about the role GIS plays for them. Throughout the course, we'll study GIS concepts and techniques that are fundamental to transportation and get hands-on experience with tools such as Esri's Network Analyst and Esri's Roads and Highways.

Geospatial perspectives and technologies play a major role in planning for and responding to emergencies. Geospatial tools - from aerial mapping techniques to data acquisition, are changing rapidly as is emergency management as the frequency and magnitude of crises and disasters are increasing.

A spatial database is the backbone of a successful organization or website that depends upon maintaining and using data pertinent to locations on Earth. In GEOG 868, Spatial Database Management, capabilities specific to Relational Database Management Systems (RDBMS) and Geographic Information Systems (GIS) are combined to teach students to create, maintain, and query spatial databases in both desktop and enterprise environments. Learn the basics of Standard Query Language (SQL) and database design/normalization, the specifics of managing spatial data in an open-source technologies context (Postgres/PostGIS) and in the context of the Esri geodatabase. Along the way, you will become familiar with spatial functions and versioning, the latter in a server environment hosted by Amazon Web Services.

The course discusses several Geopgraphical Information System (GIS) and Remote Sensing (RS) tools relevant for analysis of (problems in and aspects of) water systems. Within the course, several applications are introduced. These applications include GIS tools to determine mapping of surface water systems (catchment delineation, reservoirs and canal systems). The RS tools include determination of evaporation and soil moisture patterns, and measurement of water levels in surface water systems. In exercises and lectures, different tools and applications are offered. For each application, assignments are given to allow students to acquire relevant skills. The course structure combines assignments and introductory lectures. Each week participants work on one assignment. These assignments are discussed in the next lecture and graded. Each week a new assignment is introduced, together with supporting materials (an article discussing the relevant application) and lectures (introducing theoretical issues). The study material of the course consists of a study guide, assignments, lecture material and articles. The final mark is the average of the grades of the individual assignments.

This course focuses on a systematic approach to the design of analog electronic circuits. The methodology presented in the course is based on the concepts of hierarchy, orthogonality and efficient modeling. It is applied to the design of negative-feedback amplifiers. It is shown that aspects such as ideal transfer; noise performance, distortion and bandwidth can be optimized independently. A systematic approach to biasing completes the discussion. Lectures are interactive and combined with weekly sessions where students can work on exercises under supervision of the professors.

A Student’s Guide to Tropical Marine Biology is written entirely by students enrolled in the Keene State College Tropical Marine Biology course taught by Dr. Karen Cangialosi. Our goal was to investigate three main aspects of tropical marine biology: understanding the system, identifying problems, and evaluating solutions. Each of the sections contains chapters that utilize openly licensed material and images, and are rich with hyperlinks to other sources. Some of the most pressing tropical marine ecosystem issues are broken up into five sections: Coral Reefs and Diversity, Common Fishes to the Coral Reef, Environmental Threats, Reef Conservation, and Major Marine Phyla. These sections are not mutually exclusive; repetition in some content between chapters is intentional as we expect that users may not read the whole book. This work represents a unique collaborative process with many students across semesters authoring and editing, and therefore reflects the interests and intentions of a broad range of students, not one person’s ideas. This collaboration began with contributions from KSC students in the 2017 semester and includes work from the 2019 class, as well as new content and editorial work from 2017 & 2019 alumni. We look forward to future editions of this book. Enjoy exploring the rainforests of the sea through our collaborative project and please share with those who care!

Through two lessons and their associated activities, students do the work of scientists by designing their own experiments to answer questions they generate. Through a simple activity involving surface tension, students learn what a hypothesis is—and isn't—and why generating a hypothesis is an important aspect of the scientific method. In the second activity, with bubble gum to capture their interest, students learn to design and conduct controlled experiments to answer their own questions about the amounts of sugar (or artificial sweetener) in bubble or chewing gum.

The course aims is to understand the relation between urban design and planning and the aspects of: - sun, energy and plants - wind, sound and noise - water, traffic and other networks - earth, soil and site preparation - life, ecology and nature preservation - living, human density, economy and environment These themes in sustainable urban engineering are related to legends for design, described in a wide variety of lecture papers (720 pages, 1000 figures, 200 references, 5000 key words, 400 questions), accompanied by interactive Excel computer programmes to get quantitative insight. The assignment is an evaluation of an own earlier and future design work integrating sun, plantation, wind, noise, water, traffic, earth, land preparation, cables and pipes, life, natural differentiation, living, density, environment and proposing new legends for design.

Surface tension accounts for many of the interesting properties we associate with water. By learning about surface tension and adhesive forces, students learn why liquid jets of water break into droplets rather than staying in a continuous stream. Through hands-on activities, students learn how the combination of adhesive forces and cohesive forces cause capillary motion. They study different effects of capillary motion and use capillary motion to measure surface tension. Students explore the phenomena of wetting and hydrophobic and hydrophilic surfaces and see how water's behavior changes when a surface is treated with different coatings. A lotus leaf is a natural example of a superhydrophobic surface, with its water-repellent, self-cleaning characteristics. Students examine the lotus effect on natural leaves and human-made superhydrophobic surfaces, and explore how the lotus leaf repels dewy water through vibration. See the Unit Overview section for details on each lesson in this unit.

This unit focuses on teaching students about the many aspects of biomedical engineering (BME). Students come to see that BME is a broad field that relies on concepts from many engineering disciplines. They also begin to understand some of the special considerations that must be made when dealing with the human body. Activities and class discussions encourage students to think as engineers to come up with their own solutions to some of medical challenges that have been solved throughout the history of BME. Class time iincludes brainstorming and presenting ideas to the class for discussion. Specific activities include examination of the material properties and functions of surgical instruments and prosthetics, a simulation of the training experience of a surgical resident, and an investigation of the properties of fluid flow in vascular tissue.
