Beyond Human Intelligence: Redefining Intelligence, Jens Pohl Jun 2018

Beyond Human Intelligence: Redefining Intelligence, Jens Pohl

Architecture

The digital revolution driven by global connectivity, computing as a utility, artificial intelligence, and information sharing on an unprecedented scale is forcing the redefinition of intelligence in a broader context that extends beyond human intelligence. This paper addresses the principal characteristics of biological intelligence, as it exists on planet Earth and the form it may take in an extraterrestrial context. Human intelligence, as the most evolved form of biological intelligence on Earth, is treated as the aggregation of multiple intelligences that cannot be encapsulated in a single metric such as an Intelligence Quotient (IQ). The concept of a postbiological civilization ...


Deep Learning For Automated Image Classification Of Seismic Damage To Built Infrastructure, B. Patterson, G. Leone, Maria Pantoja, Anahid A. Behrouzi Jun 2018

Deep Learning For Automated Image Classification Of Seismic Damage To Built Infrastructure, B. Patterson, G. Leone, Maria Pantoja, Anahid A. Behrouzi

Architectural Engineering

The amount of structural damage image data produced in the aftermath of an earthquake can be staggering. It is challenging for a few human volunteers to efficiently filter and tag these images with meaningful damage information. The proposed solution is to automate post-earthquake reconnaissance image tagging activities by training a computer algorithm to classify each occurrence of damage per building material and structural member type. The approach is based on deep learning (DL), a subset of machine learning loosely based on the operation of a biologic neural system, which aims to learn and extract accurate representations from large data sets ...


Photo Tagging Tool For Rapid And Detailed Post-Earthquake Structural Damage Identification, Anahid A. Behrouzi, Maria Pantoja Jun 2018

Photo Tagging Tool For Rapid And Detailed Post-Earthquake Structural Damage Identification, Anahid A. Behrouzi, Maria Pantoja

Architectural Engineering

A significant task in earthquake reconnaissance is to conduct rapid and accurate assessments of damage to built infrastructure. This can be accomplished, in part, by analyzing the large volumes of high-resolution image data collected after a seismic event. However, detailed image tagging remains a task for trained human volunteers, which is both time-intensive and error prone. The authors developed a software tool to simplify and standardize the process of assigning damage and structure pairs to sub-regions of images. The goal of the tool is to facilitate the tagging of thousands of images from historic and recent earthquakes to train a ...


Seismic Performance Of Slender C-Shaped Walls Subjected To Uni- And Bi-Directional Loading, Anahid A. Behrouzi, A. Mock, D. Lehman, L. Lowes, D. Kuchma Jun 2018

Seismic Performance Of Slender C-Shaped Walls Subjected To Uni- And Bi-Directional Loading, Anahid A. Behrouzi, A. Mock, D. Lehman, L. Lowes, D. Kuchma

Architectural Engineering

Reinforced concrete structural walls are common as the primary lateral load resisting system in modern mid- and high-rise buildings constructed in seismic regions, yet few research programs have investigated the seismic performance of modern, slender walls with nonplanar cross-sectional geometries. Three large-scale, C-shaped wall specimens, designed per ACI 318-08, were tested under uni- and bi-directional loading at the University of Illinois at Urbana-Champaign (UIUC). This paper presents experimental results including the cyclic load-deformation response and measured versus nominal flexural/shear strengths as well as a description of damage sequence. Final failure occurs due to a flexure-tension failure of boundary elements ...

Multidisciplinary Research Efforts In Post-Earthquake Civil Infrastructure Reconnaissance, Jack Bergquist, Anahid A. Behrouzi

Architectural Engineering

To address existing challenges with filtering and classification of post-earthquake structural damage images, the authors are engaged in a multidisciplinary project to develop and train a machine-learning algorithm that identifies relevant photographs and assigns damage tags to those images. The research team is predominantly comprised of undergraduate students and is led by a structural engineering and a computer science faculty. While machine-learning algorithms have been successfully used for image tagging in a variety of fields (health care, manufacturing, etc.), the extension of this approach for earthquake reconnaissance is only just beginning. As such, the creation and development of this tool ...


Software Toolset To Enable Image Classification Of Earthquake Damage To Above-Ground Infrastructure, Anahid A. Behrouzi, Maria Pantoja Jun 2018

Software Toolset To Enable Image Classification Of Earthquake Damage To Above-Ground Infrastructure, Anahid A. Behrouzi, Maria Pantoja

Architectural Engineering

A critical task after a significant earthquake is determining the extent of damage to infrastructure networks. The decision-making process to dispatch emergency, repair, and in-field reconnaissance teams depends on whether road/railways and bridges are passible. Another concern is the rapid identification and resolution of physical disruptions to large-volume gas and water pipeline systems. After large seismic events, citizens, amateur photographers, and journalists now post thousands of photographs to formal/social media platforms. In the past, these images would have had to be reviewed by trained volunteers or expert engineers to evaluate whether: road/rail ways were significantly impacted by ...

Developing A Robust Teaching Portfolio As A Doctoral Student In A Research-Intensive Engineering Program, Anahid A. Behrouzi

Architectural Engineering

Successful faculty applications to teaching/undergraduate institutions can be difficult for doctoral students transitioning directly from a research-intensive engineering program. Oftentimes, these prospective faculty members have limited opportunities to engage in engineering education research, to serve as a primary instructor for a lecture course, or to receive adequate mentoring to prepare them for the environment of a teaching/undergraduate institution.

This paper will highlight the lessons learned by a new faculty member at a top-ranked undergraduate institution (and recent doctoral candidate at a R1 research institution) about how students can build a comprehensive teaching portfolio outside of the traditional coursework ...

Experimental And Numerical Investigation Of Flexural Concrete Wall Design Details, Anahid A. Behrouzi, T. Welt, Dawn Lehman, Laura Lowes, J. Lafave, Daniel Kuchma

Architectural Engineering

Reinforced concrete structural walls are common in mid- to high-rise structures in high seismic regions, and are expected to have good strength and ductility characteristics if designed in accordance with ACI 318-14. However, experimental and analytical investigations of reinforced concrete structural walls and isolated boundary element prisms indicate that the existing design provisions may be insufficient to provide ductile, flexure-dominated response under cyclic loading. Walls designed with an ACI compliant boundary element length are susceptible to shear-compression failures below the maximum ACI allowable shear stress of 10Acv√fc’. Also of concern is the frequent use of thinner walls in modern ...

Impact Of Cross Section, Web Reinforcement And Load History On The Seismic Performance Of Slender Concrete Walls, Anahid A. Behrouzi Nov 2016

Impact Of Cross Section, Web Reinforcement And Load History On The Seismic Performance Of Slender Concrete Walls, Anahid A. Behrouzi

Architectural Engineering

Many reinforced concrete buildings in seismic regions employ reinforced concrete shear walls as part of the lateral force resisting system and these walls often have non-planar cross-sectional geometries. To date, the majority of experimental tests on slender concrete walls have been conducted on planar walls which have been subject to low shear stress demands. An experimental program was developed to examine the response of flanged C-shaped walls with respect of load history and a computational parametric study was conducted to focus more specifically on the impact of web reinforcement for walls subject to a range of shear stress demands.

Inquiry-Based Learning To Explore The Design Of The Built Environment, Anahid A. Behrouzi, Daniel Kuchma Jun 2016

Inquiry-Based Learning To Explore The Design Of The Built Environment, Anahid A. Behrouzi, Daniel Kuchma

Architectural Engineering

Typically in introductory structural engineering courses with a lab component, the instructional approach is to present the underlying theory via pre-lab lecture/reading and subsequently have students conduct guided experiments that affirm that theory. The new Fall 2015 course offering described in this paper takes the reverse approach where students’ hands-on exploration of a concept occurs prior to formal instruction. As such, the course is based upon Da Vinci’s perspective that: “[i]n the examination of physical problems I begin by making a few experiments,…we must commence with experience, and strive by means of it to discover truth ...
