Carbon Nanoadditives To Enhance Latent Energy Storage Of Phase Change Materials, Shadab Shaikh, Khalid Lafdi, Kevin P. Hallinan

Kevin Hallinan

Latent energy storage capacity was analyzed for a system consisting of carbon nanoparticlesdopedphase changematerials (PCMs). Three types of samples were prepared by doping shell wax with single wall carbon nanotubes(SWCNTs), multiwall CNTs, and carbon nanofibers. Differential scanning calorimetry was used to measure the latent heat of fusion. The measured values of latent heat for all the samples showed a good enhancement over the latent heat of pure wax. A maximum enhancement of approximately 13% was observed for the wax/SWCNT composite corresponding to 1% loading of SWCNT. The change in latent heat was modeled by using an approximation for the intermolecular …

Fire Behavior Of Some Southern California Live Chaparral Fuels, Lulu Sun, Xiangyang Zhou, Shankar Mahalingam, David R. Weise

Lulu Sun

Wildfire spread in living vegetation, such as chaparral in southern California, often causes significant damage to infrastructure and ecosystems. In order to study wildfire spread in living vegetation, four of the most common chaparral in southern California, chamise, manzanita, scrub oak and ceanothus, were burned and compared. The observed fire behavior included mass loss rate, flame height, temperature structure and velocity field above the burning fuel bed. It was observed that flame height increases mainly with heat release rate. By using successive images of the temperature field, a recently developed thermal particle image velocity (TPIV) algorithm was applied to estimate …

Open-Ended Project Learning Experience In Graphical Communication, Lulu Sun, Christopher Grant

Lulu Sun

This paper includes the implementation of Bloom’s taxonomy in the introduction to graphical communication course and shows how students are moved up Bloom’s taxonomy by changing previous guided individual final project to open-ended projects. Instead of following the instructor’s direction to complete the model design, students are required to research the product they want to design, and build the model by themselves. The open-ended projects enable and challenge students to work on higher level of Bloom’s taxonomy by emphasizing design creativity, exploring real engineering design problem, and enhancing their oral and written skills.

Numerical Simulation Of Marina Storage Fires Using Measured Composite Fire And Thermal Properties, Lulu Sun, Aixi Zhou, Andrew Valente

Lulu Sun

Fire test data of boats in rack storage are needed to establish more specific requirements for fire control and protection for this type of vessel in high piled rack storage configurations. Since there is no current large or full scale fire test data available, we have embarked upon testing fire and thermal properties of boat material, fiber reinforced polymer (FRP) composite, by using Differential Scanning Calorimetry, and Cone Calorimeter in order to determine the most effective method to provide sprinkler protection to an indoor boat storage facility. Fire and thermal properties of FRP were obtained from experiments and incorporated into …

Numerical Simulation Of Live Chaparral Fire Behavior Using Firetec, Lulu Sun, Xiangyang Zhou, Shankar Mahalingam, Jesse Canfield, Rodman Linn

Lulu Sun

Fire spread through chaparral fuels is a significant feature of wildland fire in southern California. In order to study the detailed physical processes involved during fire spread, FIRETEC, a coupled atmosphere/wildfire behavior model was refined to examine chaparral fire behavior. FIRETEC combines a sophisticated fine-scale model to simulate a three- dimensional wildfire, moving over a terrain-following finite volume grid, with the motions of the local atmosphere. It accounts for the microscopic details of a fire with macroscopic resolution by dividing quantities into mean and fluctuating parts and the resulting transport equations are solved by using a finite difference method. In …

Using Multimedia Online Learning Tools To Supplement The Classroom Instruction, Cassandra Gribbins, Lulu Sun

Lulu Sun

This paper introduces the use of multimedia tools to create an online self-study environment to supplement the classroom instruction in Graphical Communications. The topics in this course extend from hand sketching demonstrations to the solid model creation using CAD software such as CATIA. Webcam and Camtasia software were used to capture live examples and the recorded videos were placed on Blackboard. Multimedia tools provide students an efficient way to review the topics covered in the class, in that hand sketching and complex CAD models are often difficult to interpret through words and pictures alone. The positive survey results reflect an …

The Path Of Innovation: From Traditional Classroom To Hybrid Experience, Lulu Sun, Matthew Kindy, Caroline Liron

Lulu Sun

“Introduction to Computing for Engineers” is a programming course emphasizing problem solving. However, the lack of time for practice and the algorithm-centric nature of programming results in inadequate comprehension of this course material. Through course evaluations, faculty experience, and discussions, we feel that students in a programming course should have more time for “hands-on” learning, rather than trying to absorb content through lectures. We believe that by getting students involved and excited about engineering from the beginning of their first year, we will markedly improve comprehension of the course content. To that end, a hybrid course is implemented that involves …

Work-In-Progress: Enhancing Conceptual Understanding By Using A Real-Time Online Class Response System In Engineering Courses, Lulu Sun, Yan Tang

Lulu Sun

To engage students, and assess students’ understanding in real-time, Classroom Response Systems (CRS), have been increasingly used in many engineering classrooms. Previous research has shown that CRS can enhance students’ participation, promote active learning, and develop their critical thinking skills. It can also generate either neutral or positive learning outcomes depending on whether it is combined with other cooperative learning strategies. This paper presents a collaborative study on how to combine the implementation of a web-based CRS with class discussion to clarify student misconceptions in a freshman-level engineering graphics course, a sophomore-level dynamics course, and a senior-level control systems course …

The Use Of A Real Time Online Class Response System To Enhance Classroom Learning, Lulu Sun

Lulu Sun

A real time online class response system was used in class to quickly query student population’s grasp of concepts, engage class participation, check their attendance, and clarify any misconceptions. The biggest challenges for the instructor are time needed to learn the new system, creating effective concept questions, adequate coverage of course material, and ability to respond to instantaneous student feedback. Student challenges include increased confusion if inappropriate wording for the questions, and a negative reaction to the approach in general. Overall this is a highly flexible use of interactive technology for engaging students in any discipline during the class time.

Incorporating Active Learning Into The Graphical Communications Course, Lulu Sun

Lulu Sun

Active learning, is a student-centered learning strategy which has recently gained considerable attention in higher education. The literature has shown that active learning has led to better student attitudes and improvements in their thinking, communication, leadership, and writing skills. The core elements of active learning are student activities and engagement in the learning process. As more faculty look for alternatives to traditional teaching methods they have strongly advocated active learning. However, the potential challenges for faculty with such an approach cannot be ignored such as increased class preparation time, the risks of student dissatisfaction, the use of instructional technology, and …

A Second Language Acquisition Approach To Learning Programming Languages, Rachel Cunningham, Paula Sanjuan Espejo, Christina Frederick, Lulu Sun, Li Ding

Lulu Sun

The instructional design for modules in the study was based on the evidence that learning a programming language is analogous to students acquiring a second language, and utilized tools from Second Language Acquisition (SLA) theory. A programming language has vocabulary, syntax, grammar and communicative outcomes that must be sufficiently developed for the learner to function successfully in the environment that utilizes the language. This proposed study utilized an SLA approach to programming language in a blended learning environment. Modifications to the course pedagogy included breaking the course topics into video lessons focusing on basic programming vocabulary, grammar, and syntax. These …

Teaching Higher On Bloom's Taxonomy: Experience In Introduction To Graphical Communications Course, Lulu Sun, Christopher Grant

Lulu Sun

Introduction to Graphical Communications is designed to familiarize the student with the basic principles of engineering drawing, to improve three dimensional visualization skills, and to teach the fundamentals of a computer aided design program. Much of the instruction is focused on knowledge and comprehension, low levels of Bloom's taxonomy. However, the students' ability to use this knowledge and comprehension to explore real engineering design is unknown. This paper includes the implementation of Bloom's taxonomy in the Introduction to Graphical Communications course, and shows how students are moved up Bloom's taxonomy by including a group final project into the course. Students …

Inquiry-Guided Learning (Igl) In Graphical Communications Course, Lulu Sun, Christopher Grant

Lulu Sun

Inquiry-Guided Learning (IGL) is an active learning technique which promotes students critical thinking through guided independent investigation of complex problems without a single solution, which has been studied and implemented by many researchers in science and engineering fields [1-8]. It is believed that IGL can provide an opportunity to the students to explore their desires and consequently enhance students’ learning experience in the classroom. Graphical Communications, as a common course taught at first-year undergraduate level at Embry-Riddle Aeronautical University is designed to familiarize the student with the basic principles of drafting and engineering drawing, to improve three dimensional visualization skills, …

Hybrid Course Design: Leading A New Direction In Learning Programming Languages, Lulu Sun, Matthew Kindy, Caroline Cecile Marcelle Liron, Christopher Grant, Shirley Waterhouse

Lulu Sun

“Introduction to Computing for Engineers” is a programming course emphasizing problem solving. The lack of practice time, in addition to the algorithm-centric nature of programming, results in an inadequate comprehension of course material. In the fall of 2010, three faculty members created and implemented online activities consisting of video lecture slides, and mini on-line quizzes at Embry-Riddle Aeronautical University to give students more “hands-on” learning (rather than expecting them to absorb content through lecture). Students do online lecture study by themselves, then come to the lab to practice on the following day with the instructor and teaching assistant. In the …

Automobiles And Auto Manufacturing, John Alfred Heitmann

John A. Heitmann

In several important respects the automobile and automobile manufacturing proved to be at the heart of North American life during the 1950s. The decade was one characterized as the age of tail fins and chrome, and the automobile was recognized as something far more than ordinary transportation.

Rolls Royce Declares Bankruptcy, John Alfred Heitmann

John A. Heitmann

Civilizing The Civil Engineer: How A History Course Can Serve As A Curriculum Capstone, John Alfred Heitmann

John A. Heitmann

Beginning in 1989 and then every other year thereafter, a unique course dealing specifically with the history of civil engineering has been taught to all civil engineering majors at the University of Dayton. What has evolved over time -- in response to student feedback, ongoing reform in the curriculum, and a maturing of faculty expertise -- is a course in the history of civilization that has as its major focus the discipline of civil engineering. In reality, what happens in the classroom is a far broader learning experience than either the disciplines of history or civil engineering could provide standing …

The Ilo And The Regulation Of White Lead In Britain During The Interwar Years: An Examination Of International And National Campaigns In Occupational Health, John Alfred Heitmann

John A. Heitmann

Despite the International Labour Organization's (ILO) significance for much of the twentieth century, little has been written on its early history. This case study examines the thin tightrope that the ILO had to walk in balancing the needs and demands of government, employers and labor related to the ILO's Convention No. 13 (1921), "White Lead in Painting.' Great Britain was a leading producer of the pigment white lead prior to the First World War. A government investigation was published in 1915, but measures were shelved during the War. With the peace, the focus of activity shifted to the ILO.

Review: 'Fighting Traffic: The Dawn Of The Motor Age In The American City', John Alfred Heitmann

John A. Heitmann

During the early 1960s, as the Golden Age of the automobile in America began to wane, several commentators, including Lewis Mumford, raised the critical question of whether the automobile existed for the modern city or the city for the automobile. How and when the automobile became central to urban life is deftly addressed in Peter Norton’s Fighting Traffic: The Dawn of the Motor Age in the American City. This study is certainly one of the most important monographs focusing on the place of the automobile in American society within a historical context to appear in recent times; it interestingly supplements …

Review: 'Storied Independent Automakers: Nash, Hudson, And American Motors', John Alfred Heitmann

John A. Heitmann

Nash, Hudson, and now even American Motors are automobile brands that have largely disappeared from the American memory. Yet, despite riding the twentieth-century economic roller coaster and operating in the shadow of the Big Three, these firms made sustained, significant technological and economic contributions. Charles K. Hyde’s Storied Independent Automakers is the author’s latest foray into the area of automotive business history, following work on the Chrysler Corporation and the Dodge brothers. A professor of History at Wayne State University, Hyde has written a needed critical business history on an important topic that complements the vast amount of “buff” and …
