Large-Scale Discovery Of Visual Features For Object Recognition, Drew Linsley, Sven Eberhardt, Dan Shiebler, Thomas Serre

MODVIS Workshop

A central goal in vision science is to identify features that are important for object and scene recognition. Reverse correlation methods have been used to uncover features important for recognizing faces and other stimuli with low intra-class variability. However, these methods are less successful when applied to natural scenes with variability in their appearance.

To rectify this, we developed Clicktionary, a web-based game for identifying features for recognizing real-world objects. Pairs of participants play together in different roles to identify objects: A “teacher” reveals image regions diagnostic of the object’s category while a “student” tries to recognize the object. Aggregating …

Problem-Based Learning In K–8 Mathematics And Science Education: A Literature Review, Joi Merritt, Mi Yeon Lee, Peter Rillero, Barbara M. Kinach

Interdisciplinary Journal of Problem-Based Learning

This systematic literature review was conducted to explore the effectiveness of problem-based and project-based learning (PBL) implemented with students in early elementary to grade 8 (ages 3–14) in mathematics and science classrooms. Nine studies met the following inclusion criteria: (a) focus on PBL, (b) experimental study, (c) kindergarten to grade 8 level, and (d) focus on mathematics or science content. For these studies, we examined: the definitions of PBL used, the components of PBL explicitly identified as salient to student learning, and the effectiveness of PBL. This review found that although there is no consistent definition of PBL, PBL is …

Technology From The Perspective Of Society And Public Interest, Chanwoon Park

Purdue Polytechnic Doctoral Dissertations

The ultimate goals of this study were to determine ways to reconcile technology with public interest and to understand the relationship between what we know and how we feel about technology. To achieve the goals, related literatures were reviewed; the mechanism of technology development was described with empirical data; and human perception of technology was tested with a survey. The duality of technology that implied technological inherencies of technical reason and social meanings was the principle assumption of the study. Neutrality of technology becomes a myth with the presence of social meanings embodied in technology. Given the huge impact of …

Reasoning Strategies In The Context Of Engineering Design With Everyday Materials, Marcelo Worsley, Paulo Blikstein

Journal of Pre-College Engineering Education Research (J-PEER)

‘‘Making’’ represents an increasingly popular label for describing a form of engineering design. While making is growing in popularity, there are still open questions about the strategies that students are using in these activities. Assessing and improving learning in making/ engineering design contexts require that we have a better understanding of where students’ ideas are coming from and a better way to characterize student progress in open-ended learning environments. In this article, we use a qualitative analysis of students’ responses (N = 13) in order to identify the origins of their ideas. Four strategies emerged from this analysis: unexplained …

Comparative Study Of Different Stochastic Weather Generators For Long-Term Climate Data Simulation, Sushant Mehan, Tian Guo, Margaret W. Gitau, Dennis C. Flanagan

School of Agricultural & Biological Engineering Faculty Publications

Climate is one of the single most important factors affecting watershed ecosystems and water resources. The effect of climate variability and change has been studied extensively in some places; in many places, however, assessments are hampered by limited availability of long-term continuous climate data. Weather generators provide a means of synthesizing long-term climate data that can then be used in natural resource assessments. Given their potential, there is the need to evaluate the performance of the generators; in this study, three commonly used weather generators—CLImate GENerator (CLIGEN), Long Ashton Research Station Weather Generator (LARS-WG), and Weather Generators (WeaGETS) were compared …

Eco-Friendly (Green) Synthesis Of Magnetically Active Gold Nanoclusters, Naveen Reddy Kadasala, Lu Lin, Christopher Gilpin, Alexander Wei

Department of Chemistry Faculty Publications

Au–FexOy composite nanoparticles (NPs) are of great technological interest due to their combined optical and magnetic properties. However, typical syntheses are neither simple nor ecologically friendly, creating a challenging situation for process scale-up. Here we describe conditions for preparing Au–FexOy NPs in aqueous solutions and at ambient temperatures, without resorting to solvents or amphiphilic surfactants with poor sustainability profiles. These magnetic gold nanoclusters (MGNCs) are prepared in practical yields with average sizes slightly below 100 nm, and surface plasmon resonances that extend to near-infrared wavelengths, and sufficient magnetic moment (up to 6 emu g–1) to permit collection within minutes by …

Modeling And Computation Of The Maximum Braking Energy Speed For Transport Category Airplanes, Nihad E. Daidzic

Journal of Aviation Technology and Engineering

Transport-category or FAR/CS 25 certified airplanes may occasionally become braking energy capacity limited. Such limitation may exist when heavy airplanes are departing airports at high-density altitudes, on relatively long runways, and/or possibly with some tailwind component. A maximum braking energy VMBE speed exists which may limit the maximum allowable takeoff decision/action speed V1. The ever-existing possibility of high-speed rejected takeoff in such conditions may also limit the airplane gross weight for declared available distances. To gain deeper insights and acquire better understanding of the topic, a theoretical model of the maximum braking energy and the related VMBE speed for T-category …

Society, Scientific Authority, And Linguistics: The Need For Epistemic Justification, Libby C. Chernouski

Purdue Linguistics, Literature, and Second Language Studies Conference

Many have considered Linguistics a science for decades, though linguists themselves have debated the accuracy of this characterization of the study of language. These conversations about linguistics as a science reveal a discipline intent on securing scientific status, often through rigorous methodology and theoretical frameworks mirroring the traditional sciences. If successful, however, linguistics inherits the authority of modern science, which maintains an epistemically hierarchical relationship with non-scientists. By examining and representing the epistemic relationships between expertise, authority, and science, I ask us to think of all linguistics not as a socially neutral endeavor, but as perpetuating the juxtaposition of scientific …

O(N) Iterative And O(Nlogn) Fast Direct Volume, Dan Jiao, Saad Omar

Department of Electrical and Computer Engineering Technical Reports

Abstract—Linear complexity iterative and log-linear complex- ity direct solvers are developed for the volume integral equation (VIE) based general large-scale electrodynamic analysis. The dense VIE system matrix is first represented by a new cluster- based multilevel low-rank representation. In this representation, all the admissible blocks associated with a single cluster are grouped together and represented by a single low-rank block, whose rank is minimized based on prescribed accuracy. From such an initial representation, an efficient algorithm is developed to generate a minimal-rank H2-matrix representation. This representation facilitates faster computation, and ensures the same minimal rank’s growth rate with electrical size …

Zamyatin's Reception Of Wells's Fiction, Natalia Aksenova, Marina Khatyamova

CLCWeb: Comparative Literature and Culture

In their article "Zamyatin's Reception of Well's Fiction," Natalia Aksenova and Marina Albertovna Khatyamova examine several essays written by Yevgeny Zamyatin on Herbert Wells's texts and analyse Zamyatin's reception of Wells's work. Wells's ironic mindset, plot-driven writings, and attraction to parody drew Zamyatin's attention. Zamyatin felt a rapport with the central role of plot dynamics, unorthodox socialist politics, and dystopian tendencies in Wells's fiction. Discussions of the artistic qualities of Wells's writings allow Zamyatin to expound upon his own aesthetic program, known as "synthetism." In these discussions Zamyatin interprets Wells's work as a complex interpretation of technological modernity where the …

A New Approach For Realistic 3d Reconstruction Of Planar Surfaces From Laser Scanning Data And Imagery Collected Onboard Modern Low-Cost Aerial Mapping Systems, Zahra Lari, Naser El-Sheimy, Ayman Habib

Lyles School of Civil Engineering Faculty Publications

Over the past few years, accurate 3D surface reconstruction using remotely-sensed data has been recognized as a prerequisite for different mapping, modelling, and monitoring applications. To fulfill the needs of these applications, necessary data are generally collected using various digital imaging systems. Among them, laser scanners have been acknowledged as a fast, accurate, and flexible technology for the acquisition of high density 3D spatial data. Despite their quick accessibility, the acquired 3D data using these systems does not provide semantic information about the nature of scanned surfaces. Hence, reliable processing techniques are employed to extract the required information for 3D …

Multi-Resolution Codebook And Adaptive Beamforming Sequence Design For Millimeter Wave Beam Alignment, Song Noh, Michael D. Zoltowski, David J. Love

Department of Electrical and Computer Engineering Technical Reports

Millimeter wave (mmWave) communication is expected to be widely deployed in fifth generation (5G) wireless networks due to the substantial bandwidth available at mmWave frequencies. To overcome the higher path loss observed at mmWave bands, most prior work focused on the design of directional beamforming using analog and/or hybrid beamforming techniques in largescale multiple-input multiple-output (MIMO) systems. Obtaining potential gains from highly directional beamforming in practical systems hinges on sufficient levels of channel estimation accuracy, where the problem of channel estimation becomes more challenging due to the substantial training overhead needed to sound all directions using a high-resolution narrow beam. …

Stem High School Teachers’ Views Of Implementing Pbl: An Investigation Using Anecdote Circles, Aimée L. Dechambeau, Susan E. Ramlo

Interdisciplinary Journal of Problem-Based Learning

Problem-based learning (PBL) has been gaining in popularity, especially within the context of STEM-based (science, technology, engineering, and mathematics) schools. Program assessments for these schools typically focus on student standardized test scores rather than the needs of the teachers. This study utilized anecdote circles, storytelling via moderated group discussions, to investigate teachers’ needs related to developing and implementing authentic, interdisciplinary PBL activities in an urban, public STEM high school. Teacher experiences and viewpoints were explored within three broad themes: assessment; coaching and training; and authentic learning. The analyses provide insights for transitioning a school for effective PBL implementation as well …
