Dutch open ‘world’s first 3D-printed bridge’

A 3D printer laid some 800 layers of concrete to create the eight-metre bicycle bridge in the Dutch town of Gemert Dutch officials toasted on Tuesday the opening of what is being called the world’s first 3D-printed concrete bridge, which is primarily meant to be used by cyclists. There was applause as officials wearing hard hats and workmen’s jackets rode over the bridge on their bikes at the inauguration in the southeastern town of Gemert. “The bridge is not…

Flexible ‘skin’ can help robots, prosthetics perform everyday tasks by sensing shear force

The flexible sensor skin wrapped around the robot finger (orange) is the first to measure shear forces with similar sensitivity as a human hand — which is critical for successfully gripping and manipulating objects. Credit: UCLA If a robot is sent to disable a roadside bomb—or delicately handle an egg while cooking you an omelet—it needs to be able to sense when objects are slipping out of its grasp. Yet to date it’s been difficult or impossible for most robotic…

Uber’s Open Source Distributed Deep Learning Framework

Over the past few years, advances in deep learning have driven tremendous progress in image processing, speech recognition, and forecasting. At Uber, we apply deep learning across our business; from self-driving research to trip forecasting and fraud prevention, deep learning enables our engineers and data scientists to create better experiences for our users. TensorFlow has become a preferred deep learning library at Uber for a variety of reasons. To start, the framework is one of the most widely used open…

TC4D: Data Quality By Engineers, For Engineers

Changing an engineering culture is one of the biggest challenges for any organization. It requires challenging an existing way of working, and introducing compelling improvements that are adopted by individuals as well as the departments. Tackling tech debt instead of amassing it, using new tooling and infrastructure, or in this case, increasing test coverage. After leading numerous failures to influence the quality of Spotify’s big data, there was finally one success. TC4D, Test Certified for Data-Focused teams, is a gamified,…

Uber’s Driverless Car Plans to Reinvent Riders’ Experience

Driverless cars are the future and we all know we are going to see a lot of them around. The level-4 driverless car could be a reality by 2025 while a fully autonomous car may take more time. Few among us may own them and many of us will be riding in a rented driverless Uber as the company is channelizing its R&D to build a robotic chauffeur. Also, Uber is not only working to install a driverless car computer…

Israel Aerospace Industries, Hankuk Carbon, to make drones

Israel Aerospace Industries says it has formed a joint venture with Korean company Hankuk Carbon to make unmanned aircraft together. It says the new company, called Korea Aviation Technologies, will develop drones with vertical takeoff and landing capabilities. Its products will be aimed at both the military and civilian markets in South Korea. The two companies signed their joint venture agreement on Tuesday at the International Aerospace and Defense Exhibition in Seoul. Each will hold a 50 percent stake…

Engineers could learn a lot from dance when designing urban transport

Credit: HelloRF Zcool/Shutterstock.com There is little more important for the sustainability of cities than the ways we move around them. With transportation estimated to account for 30% of energy consumption across the majority of the world’s most developed nations, reducing the necessity for energy-reliant vehicles is fundamental to addressing the environmental impact of mobility. But as cities become the predominant habitat for most people in the world, it is important to think about other kinds of sustainability too. The ways…

3-D mapping of rooms using radar

Developed by the Institute of Integrated Systems in Bochum, the radar sensor is no bigger than this. Credit: © Roberto Schirdewahn Engineers from University Alliance Ruhr have developed novel signal processing methods for imaging and material characterisation with the aid of radar. Their long-term objective is to use these techniques in combination with radar-based localisation of objects. Their vision is a flying platform capable of generating a three-dimensional representation of its surroundings. The technology might be, for example, useful for finding…

Predictive Analytics Can Be a Powerful Tool That Can Help a Business

Every business has to scramble so that it can provide a unique and ultimate experience for every transaction that is made by its customers. In today’s world, customers do not think twice before they abandon vendors or providers or even give up transactions because they have had a poor experience in dealing with a particular business. Customers in today’s world require services to be delivered with a smile and pleasant manners – and this is needed even when you are…

Choosing a HR Software System That Boosts Productivity and ROI

Believe it or not, there is a strong link between the happiness of employees and profitability of the company that they work for. In fact, 2014 saw Fortune’s 100 Best Companies to Work For increase their profits by an average of 22.2%, which is a sizeable increase when you consider the prevailing economic climate. Optimising employee productivity is easier said than done, however, particularly when you consider that each member of staff has their individual cost base. In order to…
