Sessionizing Uber Trips in Real Time

By Amey Chaugule In one sense, Uber’s challenge of efficiently matching riders and drivers in the real world comes down to the question of how to collect, store, and logically arrange data. Our efforts to ensure low wait times by predicting rider demand, while simultaneously enabling drivers to use the platform as effectively as possible by taking into account traffic and other factors, only magnifies the scope of data involved. To better focus how we manage the massive amounts of real-time…

EU Terrorist Content Online proposal – political haste and unintended consequences

Photo by Sara Kurfeß / Unsplash In September, the European Commission presented a legislative proposal to address the removal of terrorist content online. There has been significant political pressure, particularly as the EU elections of 2019 approach, towards internet companies taking on increased responsibility in the area of terrorist propaganda online. This proposal would be a marked move from various voluntary initiatives taken up by some social media companies in recent times towards a legal responsibility framework for many.  …

Ultrafast laser provides unique research opportunities

A unique, interdisciplinary instrumentation grant from the National Science Foundation will have excellent impact on research done in the College of Engineering. Suchi Guha of the MU Physics Department was the principal investigator on a Major Research Instrumentation award from the NSF, and Heather Hunt of the Biomedical, Biological and Chemical Engineering Department was a co-investigator. The grant allowed Mizzou to purchase an ultrafast, femtosecond laser, which has a wide variety of research applications. Hunt “The proposal is really neat…

Aluminum nitride to extend life of solar power plants

NUST MISIS scientists together with their colleagues from the Central Metallurgical R&D Institute (Cairo, Egypt) have developed a composite material which will extend the life of solar towers — installations for collecting Solar thermal energy — from 2-3 to 5 years. The research article has been published in the Renewable Energy journal.

Lessons from 1.5 Years of our AI & Data Reading Group

Group photo of the reading group for Data Standardization, Knowledge Graphs, Natural Language Understanding, and Conversational AI at LinkedIn, celebrating the group’s 17-month anniversary   Co-authors: Qi He and Jaewon Yang  For the past 17 months, a group of roughly 20 people of different ages, genders, and backgrounds have been meeting every Friday in LinkedIn’s Silicon Valley HQ. At these meetings, they discuss cutting-edge research in specialized areas of machine learning and artificial intelligence (AI). Seeing this group in action,…

Screaming Circuits: The End is Near

Let me be more specific. The end of the year 2018 is near. Some might argue that with air conditioning to keep us cool in the summer, heating to keep us warm in the winter and an industrialized global food supply chain to keep us fed through all seasons (romaine lettuce notwithstanding), such distinctions as “New Year’s” become rather arbitrary and irrelevant to the survival of the species. That may be true in the purest sense, but most people aren’t…

Creating digital twins of materials

Data spaces can be used to integrate all types of materials information into digital networks – a valuable tool for production in the context of Industrie 4.0. Credit: Fraunhofer IWM To ensure the digital networking of production systems and the optimization of material-specific requirements, we need to measure, analyze and replicate the changes in material properties in a process in which “digital twins” of materials are created. The materials data space developed by Fraunhofer researchers has laid the groundwork for…

How engineers are straightening the Leaning Tower of Pisa

Still beautifully oblique “It’s still straightening,” said engineer Roberto Cela, gazing at the Leaning Tower of Pisa gleaming in the autumn sunshine of northern Italy. “And many years will have to pass before it stops.” The gravitationally-challenged landmark is leaning less after years of ambitious engineering work. Fortunately for the millions of tourists who come here every year, the 57-metre (186-feet) tower remains beautifully askance. The medieval bell tower, a symbol of the power of the maritime republic of…

Using AI and satellite imagery for disaster insights

WHAT THE RESEARCH IS: A framework for using convolutional neural networks (CNNs) on satellite imagery to identify the areas most severely affected by a disaster. This new method has the potential to produce more accurate information in far less time than current manual methods. Ultimately, the goal of this research is to allow rescue workers to quickly identify where aid is needed most, without relying on manually annotated, disaster-specific data sets. HOW IT WORKS: Researchers train models on CNNs to…

Pursuit of Excellence banquet celebrates success, inclusivity

Dean Loboa (far right) joined the winners of the 1907 Women in Engineering Awards, given at Thursday’s second-annual Pursuit of Excellence Banquet. The Mizzou Engineering Office of Diversity and Outreach Initiatives and the MU Center for Academic Excellence and Success hosted the second-annual Pursuit of Excellence Banquet on Thursday in Columbia. The banquet celebrates outstanding students, faculty and staff from Mizzou Engineering who are from traditionally underrepresented backgrounds in engineering and those who work to support their efforts. A variety…
