Classroom research as teacher-researcher

In the field of education, research projects that involve both the researcher and teacher being the same person are common today, as attested by the significant number of teacher-researcher studies. One issue confronting the dual role of teacher-researcher is the nature of interaction between the underlying goals that come with each of these roles. There are some researchers who express concern that the combination of these goals within the teacher-researcher may compromise either or both of the work of teaching and research in an unproductive way. This paper is an account of my adventure in attempting to fulfil both teaching and research goals in my work as teacher-researcher in a year 7 (Secondary One) geometry class in Singapore. My experience is then re-interpreted in the context of the ongoing conflicting-versus-complementary talk on the interaction between teacher/researcher &lsquo;selves&rsquo;. A model is proposed to account for the seemingly opposite sides of the camp as reported in the literature on this issue.<br /

Dimensional reduction in nonlinear filtering: A homogenization approach

We propose a homogenized filter for multiscale signals, which allows us to reduce the dimension of the system. We prove that the nonlinear filter converges to our homogenized filter with rate $\sqrt{\varepsilon}$. This is achieved by a suitable asymptotic expansion of the dual of the Zakai equation, and by probabilistically representing the correction terms with the help of BDSDEs.Comment: Published in at http://dx.doi.org/10.1214/12-AAP901 the Annals of Applied Probability (http://www.imstat.org/aap/) by the Institute of Mathematical Statistics (http://www.imstat.org

Building Mechanical Intuition Through Hands-On Learning with Truss Components

Statics is an introductory Mechanical Engineering class that all types of engineers are required to take. One difficulty students often face is the inability to visualize how forces are transferred through truss systems. The goal of this project is to create a hands-on system that students can interact with to reinforce their understanding of tension and compression in an affordable manner. This project will build on previous 3-D modeling work to create an entire 3-D printed truss system for in-class demonstrations and may provide a framework for future student projects. The interactive system will demonstrate the effects of a load by using force-dependent, length-adjustable plastic components as bars and foam ear plugs as joints. This poster will discuss the educational benefits of the project for Statics students and will also provide Solidworks parts files for dissemination. This hands-on tool built to enhance comprehension of forces may lead to reduced lab fees in follow-on upper division courses that demonstrate tension and compression by using expensive metals and heavy machinery. This project provides an affordable and easily accessible solution for learning the effects of tension and compression in a truss system, and a live demonstration will be held at the Creative Collaborations Undergraduate Research Conference

The physical and thermal properties of modified rotational molding grade silane cross-linked polyethylene compound

This study is aimed at investigating the physical and thermal properties of the modified rotational molding grade cross-linked polyethylene compound with respect to process ability. Rotational molding grade High Density Polyethylene (HDPE) was blended at various compositions with HDPE and Low Density Polyethylene (LDPE) using twin screw extruder. The melt index of the blends was studied according to ASTM D 1238. The blended compositions were chemically cross-linked with various amount of silane cross-linking agent using two roll-mill. Water curing was then undertaken at 100°C in water bath for 4 and 8 hours. Gel content was measured according to ASTM D 2765 to determine the degree of cross-linking. For thermal analysis, only samples crosslinked with 2.0 phr silane cross-linking agent were investigated on the Differential Scanning Calorimetry (DSC) according to ASTM D 3417. The thermal stability test of the silane Crosslinkable Polyethylene (XLPE) was performed by Thermogravimetric Analyzer (TGA) according to ASTM D 3850. Results on melt index (MI) indicated that the rotational molding grade HDPE blended with HDPE showed higher MI compared to that with LDPE thus improved process ability. The density of rotational molding grade HDPE with HDPE was slightly increased whereas that blended with LDPE was slightly decreased. Samples blended with HDPE, melting temperature, Tm, barely changed and degree of crystallinity, Xc, decreased with compositions. Samples with LDPE Tm and Xc decreased with compositions thus improved process ability. As the silane concentrations increased, the gel content after curing was also increased but independent of compositions. Longer curing time resulted in higher gel content. Thermal stability of the crosslinked HDPE was higher than the uncross-linked HDPE, thus silane cross-linking help to stabilize the blends
