Object Recognition Based On Shape And Function: Inspired By Children's Word Acquisition, Akihiro Eguchi
Object Recognition Based On Shape And Function: Inspired By Children's Word Acquisition, Akihiro Eguchi
Inquiry: The University of Arkansas Undergraduate Research Journal
This paper explores a new approach to computational object recognition by borrowing an idea from child language acquisition studies in developmental psychology. Whereas previous image recognition research used shape to recognize and label a target object, the model proposed in this study added the function of the object resulting in a more accurate recognition. This study makes use of new gaming technology, Microsoft’s Kinect, in implementing the proposed new object recognition model. A demonstration of the model developed in this project properly infers different names for similarly shaped objects and the same name for differently shaped objects.
Wi-Fi Sensing Algorithms Utilizing Zigbee Rf Receiver For Use In Emergency Communications Mesh, Alexander H. Nelson
Wi-Fi Sensing Algorithms Utilizing Zigbee Rf Receiver For Use In Emergency Communications Mesh, Alexander H. Nelson
Inquiry: The University of Arkansas Undergraduate Research Journal
This thesis examines a low-power Wi-Fi sensing wake-up controller for an emergency communications mesh network; the goal of the research study is to progressively develop a prototype system that could be used in a live environment. Wireless network protocols are reviewed, in addition to a limited view of cluster analysis, in order to introduce relevant receiver concepts crucial to understanding this study. Algorithms for system implementation are developed, and pseudocode, designed to be configurable and platform-independent, is given for each. The system’s design goals are identified, followed by a discussion on approaches and optimizations in order to maximize the system’s …
Investigating 3 Axis Cnc Processes For Creating 3d Objects, Michael Jake Newsum
Investigating 3 Axis Cnc Processes For Creating 3d Objects, Michael Jake Newsum
Inquiry: The University of Arkansas Undergraduate Research Journal
Using 3 axis CNC (computer numerical code) routing processes of the Visualization Lab, the CNC was tested for 3D object milling. The CNC process was designed for manufacturing 2D cut out objects with or without a 3D surface. The processes of modeling the object, using CAM (Computer Aided Manufacturing) programs, producing the Toolpath, post processing, editing G Code, positioning the stock material, and setting the machine origin were tested for an understanding of what changes had to be made to the process to accurately mill and cut out 3D objects. Solutions were discovered through digital and physical setups that are …
