VR Model Of The Milky Way Opens New Doors In Surgery

Using data from over a billion stars, a research team at Lund University in Sweden are developing an interactive 3D model of the Milky Way galaxy. This could enable new types of discoveries that aren’t possible with current tools – perhaps even unraveling how the Milky Way was formed. The data being used is from the Gaia satellite that was launched in 2013. It orbits the Earth and collects data from over a billion stars.

This will be the best map of the Milky Way we have so far. A Virtual Reality immersion is something we are very keen on exploring, as it can help us identify patterns and structures in very complex data”, explains Oscar Agertz, astronomy researcher at Lund University.

The research could also potentially allow surgeons to work together in medical examinations despite being on separate continents.

5G Technology, 22 Times More Powerful Than 4G

Researchers at the universities of Lund (Sweden) and Bristol (UK) have conducted a number of experiments using a form of 5G technology called Massive MIMO (multiple input, multiple output), and set not one but two world records in so-called spectrum efficiency for wireless communication. Spectrum efficiency measures how much data can successfully be packed into a radio signal transmitted from an antenna.

This 5G technology developed by the researchers is extremely efficient – in fact, the most efficient technology ever when it comes to managing many simultaneous users. The latest world record was set when researchers from Lund and Bristol attained more than 20 times the total data speed of today’s 4G technology, thereby almost doubling the previous record where they, using the same technology, achieved a twelve-fold improvement.

Setting a new world record was a significant event as it demonstrated that it is possible to transmit 22 times more data compared to current wireless systems. Although the goal is for 5G to increase the total transmission capacity by a factor 1 000, this is still a big step”, says Steffen Malkowsky, researcher in Electrical and Information Technology at the Lund University Faculty of Engineering.

Electric Road For Electric Cars

In recent years, electric roads have emerged as potential alternatives to the heavy and expensive batteries currently needed in electric road vehicles. Now researchers at Lund University in Sweden have developed an even smarter technology – that doesn’t require digging up stretches of road to install the system. Instead, a small conductive rail is laid on top of segments of the road.

The vehicle has three contact points with the road through which it connects to the power supply. It works much in the same way as a charging pole; except the vehicle charges both while moving and standing still”, explains Mats Alaküla, professor of industrial electrical engineering and automation at Lund University.

The rail is only active when covered by the vehicle, making it a safe option for cities. The system notices when you leave a driving lane and automatically disconnects the “pick up”– reconnecting when you are back. As a driver you wouldn’t notice anything beyond a symbol on your dashboard.

The current challenges for electric vehicles include the large and expensive batteries needed and the limitations in driving range. An electric road solution reduces the need for batteries by up to 80%.

Modern conventional electric vehicles have a driving range of 300-500 kilometers. With an electric road system covering the national and European road network,  you only need a battery range of 50-100 kilometers, to keep you covered if you come to the end of an electric road”, says Mats Alaküla. For longer distances, around 50% of the national and European road network  (e.g 10 out of 20 km on average) needs the rail installed for vehicles to keep running non-stop. The implementation would be different in cities than in other areas, stresses Mats Alaküla. In cities, the rail would be installed strategically on select road segments, bus stops, loading docks for trucks or waiting lanes for taxis, for example. This way, more complicated areas like intersections or roundabouts can be avoided.

Electric Car For MegaCities

Uniti Swedish startup is building Uniti One, an electric car for crammed cities. There have been 3,000 pre-orders for its first model. Uniti One will have “75% lessenvironmental impact than standard electric vehicles. Uniti aims for its first cars hit European roads in 2019.

Uniti is betting on a small and affordable electric car to meet an explosion of interest in the coming decade. And if Swedish car fans are anything to go by, it may work. Just a couple of months after making its first model available for pre-order through Swedish electronics retailer Mediamarkt, more than 3,000 people have queued up for the company’s sleek two-seater. The total value of the pre-orders, which are fully refundable, now correspond to some 500 million krona (€50 million). “This is an important milestone for our new company,” says Robin Eriksson, Chief Marketing Officer at Uniti in a press release, adding: “We are now working intensively with our development and production partners to finalise supply potential so we can scale accordingly.

Uniti One was unveiled in December and will retail for around 150k SEK ($17,000) a piece. After releasing the vehicle for pre orders this winter, interest has exploded in Sweden. Uniti’s two-seater has been designed with megacities in mind. Initially developed out of Lund University in Southern Sweden, Uniti’s dream of a small-scale electric urban vehicle became a freestanding project in 2016, when the new startup took in just over SEK 12 million ($1,35M) to create a production-ready prototype.

Uniti‘s vehicle is expected to have a range of 150 to 300 kilometers, and will be tailored for urban environments on account of its small size. Uniti claims its car emits 75 percent less carbon-dioxide over a lifecycle than many of today’s electric vehicles.

We see our vehicle as a complement to the bigger cars and will be a second car for many customers. A small two-seater is easier sell,” Eriksson said.
