AI disruption in e-commerce – Wayfair Data Science talk on PAPIs |

Wayfair offers a zillion things home, with one of the world’s largest online selections of furniture, home furnishings, décor and goods, including more than eight million products from over 10,000 suppliers. Wayfair’s expanding Visual Search team is leveraging deep learning and our expansive catalog of images to create an exciting new way for shoppers to find the perfect product for their homes. The following talk by David Drollette, Director of Data Science at Wayfair, given at the 2017 PAPIs conference…

A hard material engineers hope to make harder

For thousands of years, people have built civilizations with concrete made from readily available local materials. Just mix and heat, add some sand, stone and water and put it where you want it. Of course, give it time to harden – that is, after you have left your hand print or initials. So it’s no surprise that concrete is the world’s most widely used building material. Twice as much concrete has been used to build Pittsburgh – and everything else…

Six Political Questions for Engineers to Think About

Provided below are six political questions that engineers and engineering organizations should be thinking about. Question 1 – Polls and political commentators have highlighted that this is the most politically divided the country has been since the Civil War and Reconstruction.  Assuming this is true – how should the engineering communities be thinking strategically about this political divide? The graphic on the cover page is from the Federal Reserve Bank of Philadelphia annual Partisan Conflict Index.  The index was developed…

A new way for developers to monetize on Square’s platform

Following our announcement in September that we’re working with Eventbrite to expand our offering for marketplaces, we’re excited to share that now marketplaces and platforms using our eCommerce API or Square Checkout can pay out their merchants and get paid themselves. In the last few months we’ve worked closely with several developers and partners including Weebly and Schedulicity to test, refine, and provide feedback about the product. Using Square Multi-Party transactions, Weebly was able to expand Square’s offering to all…

Engineering Uber’s On-Call Dashboard – Uber Engineering Blog

Uber’s on-call engineers facilitate seamless experiences for riders and drivers worldwide by maintaining the 24/7 reliability of our apps. To execute on this reliability, however, we need to ensure that our on-call teams are set up for success. Until January 2016, our on-call toolbox was dispersed across several systems, making it difficult for engineers to respond to alerts quickly and efficiently. Compounding this was the inability of the tracking solution we were using at the time—email reports—to effectively relay contextual…

Constructing buildings with re-useable components

The Institute for Civil Engineering and Environment (INCEEN) at the University of Luxembourg have signed a “memorandum of understanding” with the Suisse Federal Laboratories of Materials Science and Technology (Empa) of the domain of ETH Zürich to collaborate on research on energy efficiency in the construction sector. As the building sector is generating a large amount of CO2 emissions, resource consumption and waste production, new eco-construction approaches are needed. Therefore, the first collaboration project entitled “Eco-Construction for Sustainable Development” (ECON4SD)…

Researchers achieve 4-D printing of programmable shape-changing structures

3D Printing and Additive Manufacturing is the only peer-reviewed journal focused on the rapidly moving field of 3D printing and related technologies. Credit: Mary Ann Liebert, Inc., publishers A new study describes 3D printing of Shape Memory Polymers to produce active meta-materials that can be programmed to form versatile shapes and are then able to recover their original state when heated to above their activation temperatures. This innovative combination of 3D printing, thermoviscoelastic meta-materials, and programmable design to create 4D…

AR glasses help surgeons when operating on tumors

AR glasses enable the doctor to precisely locate the site of the lymph node during surgery. Credit: Fraunhofer-Gesellschaft Malignant tumors often form metastases that spread to other parts of the body via the lymphatic system. High surgical skills are required to identify the precise location of the affected lymph nodes, enabling them to be completely removed. Fraunhofer researchers have developed a navigation aid that simplifies such interventions. 3-D-ARILE is an augmented reality (AR) system that superimposes a virtual image of…

Integrated technologies to recover metal and plastic from electronic waste

VTT Technical Research Centre of Finland has developed a new electronic waste recycling concept that combines a range of technologies and reduces waste. One of the technologies included in the concept is gasification, which is used to recover not only metals and rare-earth elements from the waste but also organic components that can be used to produce energy or products, such as plastic and chemicals. VTT has brought together a group of Finnish partners to promote material-efficient production. Vast amounts…

Stem cell laboratory in a bag

The mini laboratory is 150 mm long, 120 mm wide and 20 mm high. The screw cap is made using 3D printing. Hydrophilic spots are visible on the upper interior surface of the bag. Credit: Fraunhofer-Gesellschaft Human stem cells are considered a major new hope in the field of medicine. In the future, it is expected that they will make it possible to treat a wide range of ailments such as neurodegenerative diseases. With LabBag, Fraunhofer researchers have developed an…
