alloying materials like nickel, cobalt and chromium might cause allergies andcould prove to be carcinogenic8.To overcome these drawbacks, biodegradable polymers have been developed. The first use ofbiodegradable polymers was for a resorbable suture (Dexon) in 1962. Polydioxanon (PDS),Polyglycolic acid (PGA), Polylactic acid (PLA) and their copolymers are being used forproducing these polymers. In the initial stages of healing, these polymers maintain theirmechanical strength and fragment fixation. As the bone healing progresses, the implantgradually decomposes (Figure 1) and the loads are transferred to the healing bone9. Thesepolymers gradually undergo hydrolysis10, the byproducts of which are eliminated throughnatural metabolic means. The

, Laboratory II,junior level chemical engineering students were required to (1) perform simple heattransfer experiments using inexpensive materials that are readily available in mostengineering departments and (2) compare the experimental results with literaturecorrelations. The design, implementation and analysis of two of these experiments aredescribed in this presentation.Laminar flow heat transfer coefficients were measured for the flow of ethylene glycolthrough 11 ft x 3/16 in i.d. coiled copper tubing by heating the coil in an agitated waterbath at about 150ºF. The temperature of the exiting ethylene glycol was recorded as afunction of flow rate and was used to determine the duty of the copper coil and theexperimental heat transfer coefficient

for CHEG 3143, HeatTransport, and CHEG 3232, Laboratory II, junior level chemical engineering studentswere required to perform simple heat transfer experiments using inexpensive materialsthat are readily available in most engineering departments. The design, implementationand analysis of two of these experiments are described in this presentation.The thermal conductivities of polycarbonate, polystyrene and plywood were individuallydetermined by sandwiching the test material between three 1 ½ in x 12 in x 18 inaluminum plates. After the center plate was heated to 70-80°C, the “sandwich” wasassembled and insulated on all sides. The temperatures of the center plate and one of theouter plates were measured with time and used to calculate the rate

In fact, each year, overthree billion person-hours are spent under severe weather watches4. Though one may live inOklahoma or Kansas and not be affected by a tornado one year, he or she may very well becomea victim in any year to come, and in some cases you may become a victim more than once in alifetime as depicted in Figure 1. Regardless of circumstances, a safe room has the potential foreasing people’s restlessness and saving their lives when they find themselves in the path of astorm.

In response, there are anumber of new textbooks and enrichment materials targeted for the Advanced PlacementStatistics curriculum, which develop the role of statistical thinking in addressing problems ofpractical interest. Other recent publications, such as the NCTM Navigation through DataAnalysis series 4, provide materials and activities for students to learn statistical thinking by‘interrogating’ data.

With gripper attached, the robot has sixdegrees of freedom. Figure 1 illustrates the robot arm. This design permits the end effector to bepositioned and oriented arbitrarily within a large workspace. The length of the links and thedegree of rotation of the joints determine the robot’s work envelope. Figure 1. Robot Arm.

Finite Element 1, 4Analysis to lower division engineering students and whether it can be done effectively. Asearly as 1992, Steven Howell 3 pointed out that the Finite Element Method (FEM) is typicallyintroduced in the upper level engineering courses. With the ‘integrated design software’available for the PC, it is now possible to expose freshman level students to the finite elementmethod without overwhelming them in the detailed math required to set up a model.” In the 2Spring 1999 issue of the Engineering Design Graphics Journal, William Cole stated, “Solidmodeling

, motivate them to stay in engineering. The seven issues arerelated to two key areas, projects and relationships between engineering and mathematics andscience classes.Issues related to projects are: 1). Students and faculty members perceive projects currently being used in first-year engineering courses as “build and see” where students proceed through trial and error with little connectivity with the sciences or mathematics [3,4]. Some programs have provided simulation tools to enable students to predict the performance of their design proposal [5,6]. 2). Engineering faculty members thought that success of a project relied more on the fabrication skill as opposed to application of the engineering design

-Southwest Annual Conference Texas A&M University-Corpus Christi Copyright © 2005, American Society for Engineering Educationstorage. Kumar et. al. (2004)1 illustrated the advantage of injecting CO2 in the bottom part of anaquifer. The injected CO2 will rise toward the top, leaving behind a residual saturation. In aproperly designed process, all the CO2 will become trapped or dissolved in the brine before itreaches the top.Buoyancy is the driving force behind CO2 rising in these aquifers due to the density differencebetween CO2 at aquifer conditions and water. The density of CO2 at aquifer conditions isapproximately 700 kg/m3 and water is about 1000 kg/m3. The velocity at which CO2 rises

, while at the same time exposingthem to applications from science and engineering. The objective of such exposure throughoutthe curriculum is to catch the interest of students at an early stage, and thus encourage them topursue those career paths.The project uses web-based modules to meet three goals. One is to increase interest in computerscience and engineering at the lower level courses for majors and non-majors. A second goal isto improve retention by offering support for upper level courses. The third goal is to providesupport to the partnership project with TTU and TI.

. Application of Concept Mapping in ThermodynamicsThermodynamics is taught at sophomore and junior level in mechanical engineering.Principles of thermodynamics are used in several other courses as heat and mass transfer,internal combustion engines and fluid dynamics. Few governing equations form thefoundation of this subject. However, there are large number of variations of theseequations that are used to solve different problems.Interactive Scheme for Problem SolvingConcept mapping based problem solving scheme can be made interactive by the use ofvarious software tools. In most cases the solution steps in thermodynamic problems aresimilar to any other engineering problem. Figure 1(a) shows a generalized solutionscheme of any engineering problem

Such projects can either beused as a stand alone cap-stone design or to assist the student to accomplish amultidisciplinary design projects in collaboration with other engineering disciplines. IntroductionABET program criteria for electrical engineering curriculum require that the curriculummust provide the depth and breadth across the range of engineering topics implied by thetitle of the program [1].

The labprovided the resources for a lab course to accompany an introductory senior-level courseon robotics and mechatronics. The resources additionally came to be used to supportsenior capstone engineering design projects, senior/junior Independent Study courses,junior/sophomore Supervised Study courses, as well as faculty research in the areas ofcontrol, robotics, and mechatronics. Most of the projects involved teams of three or morestudents. A summary of the projects and their outcomes is given in Table 1.Computer hardware and software issues are
