Continuous learning and improvement are the key to be competitive and successful for any profession or any entrepreneurial venture, and even for any individual in his day-to-day dealings with surroundings. A recent research concluded that basic biases that stand in the way to the learning and improvement process are: focusing too heavily on successes, acting too quickly, trying too hard to fit in, and relying heavily on experts. Focussing heavily on success leads to unreasonable fear of failure thereby inhibiting risk taking ability of a person, focussing on past performance rather than potential brings in pessimism, and relying on outside experts blocks innovative ideas emanating from within the organization. Managers therefore need to treat mistakes of workers as learning opportunities, recognize and foster workers' capacity for growth, and conduct data-based project reviews rather than perception-based reviews. To counter bias, leaders need to recognize the potential of workers, encourage them to cultivate their individual strengths and to speak up whenever they have innovative ideas, and empower them to solve problems instead of turning to external experts.

Li–Fi: A Revolutionary Wireless Technology that is 100 Times Faster than Wi–Fi
Imagine a world where every one of the billions of light bulbs in use today is a wireless hotspot delivering connectivity at speeds that can only be dreamed of with Wi–Fi. All this is possible now with the invention of a new technology called Li–Fi. Li–Fi, a new wireless technology developed by German physicist Harald Haas and a group of people working on this technology, in actual tests showed to deliver the speed that is 100 times faster than today's Wi–Fi technology. A Li–Fi–enabled light–bulb can transmit data with the speed of 1 gigabit per second (Gbps) that means a high–definition film can be downloaded within seconds. The real–world tests are yet to be carried out, but laboratory tests have shown theoretical speeds of 224 Gbps.

Similar to Wi–Fi, Li–Fi delivers high–speed, bidirectional, and networked mobile communications. It refers to visible light communications (VLC) technology, and promises huge speed advantages as well as more–secured communications and reduced device interference. When a constant current is applied to an LED (light–emitting–diode) light–bulb, a constant stream of photons is emitted from the bulb which is observed as visible light. If the current is varied slowly, the output intensity of the light dims up and down. Because LED bulbs are semiconductor devices, the current, and hence the optical output, can be modulated at extremely high speeds which can be detected by a photo detector device and converted back to electrical current. The intensity modulation is imperceptible to the human eye, and thus communication is just as seamless as RF [radio frequency technology]. Using this technique, high–speed information can be transmitted from an LED light–bulb.


On–Site 4D Construction Simulations
In construction, 4D Scheduling is commonly used for years. Generally, 4D scheduling helps you to combine the project's 3D model with a construction schedule. These simulations are useful for validating a work plan and for ensuring that it is physically possible and efficiently and safely uses the resources. Over the last 50 years, if we compare with other industries, construction has improved productivity. Scheduling and enhanced planning is our greatest opportunity for improvement.

Currently, drawings are getting designed in 3D and then printed in 2D in a much easier and better way for superintendents and foremen to read and understand the drawings. Our other enhancements are safety warnings in events (before entering a confined space) or the swing radius of a crane. If properly executed, possibilities are endless to save hundreds of millions of dollars by the construction industry annually.


Autodesk Expands Photorealistic Rendering Options
Autodesk has built up its in–house rendering expertise through acquisition and research. They have launched two ray–tracing engines in the market: one is embedded within the design workflow, and the second for standalone rendering projects.

Ray tracing is the most popular technology for turning CAD models into polished, photorealistic visual images .This technology imitates the real–world effects of light bouncing off objects. Instead of a manual input, ray tracing makes light a calculated data type allowing ray–tracing solutions to work much faster than other approaches to photorealistic rendering. Every digital ray of light can be investigated repeatedly as it moves and bounces through the model. The image becomes more realistic and mature, depending upon the duration a ray tracing engine is working on a model.

Autodesk is updating many products with a new ray–tracing engine it developed in–house. Autodesk Raytracer is now the part of current versions of AutoCAD, Navisworks, Revit, and Showcase. It is available as a free Autodesk Labs Technology Preview for 3ds Max.

For visualization specialists, third–party ray–tracing software provides a broad set of tools to manipulate the rendering. Whereas in contrast, Autodesk Raytracer is a generalist tool that provides a simplified feature set. Mental ray software ‘NVIDIA’ is included in Revit and remains an option where more complex features are desired, such as Daylight Portal.
