The Joint Theater Level Simulation (JTLS®) at the I/ITSEC 2010

 The 2010 Interservice/Industry Training, Simulation and Education Conference (I/ITSEC) saw JTLS participating at the NATO booth as an integral component of NATO’s Education and Training Network (NETN) architecture. This event was the culmination of months of testing NETN in preparation for its operational use throughout NATO. Other simulations in this federation included KORA (Germany), TYR (Sweden), JCATS (US), VBS2, ORQUE (French), and WARGRAM (French). The NETN Federation Object Model and agreements were developed to create a persistent federation specification, allow participation by geographically distributed simulations, enable multiple levels of aggregation for game objects and to share tasks over many different simulations.

 During the 3 days of demonstrations, R&A engineers showed (1) several JTLS aggregate ships and their movements that were reflected by the other simulations; (2) JTLS aircraft, both military and commercial, being flown and reflected by other air simulations; (3) a de-aggregated ground battalion, as defined in the scenario Order Of Battle, was reflected by the VBS2 virtual environment while moving and at different damage states and (4) creation of several aggregate level, air base and squadron units.

NATO and R&A engineers demonstrated many JTLS features, including batch orders for ground unit movement and ATO processing, to many non-US visitors including the United Kingdom, Saudi Arabia, Canada, Kuwait and India. Representatives from several US businesses were also briefed on the nuances of JTLS.


Can you retroactively put yourself in a computer simulation?

Nick Bostrom’s simulation argument has suggested that we might be in a computer simulation. An argument is made that our actions are relevant here, and that some actions that we might perform could retroactively put us into a computer simulation.

This does not mean that we could do things that cause us to enter a simulation in the future, such as mind uploading. Rather, the argument is that we might be able to do things which result in us having been in a computer simulation all along. Of particular relevance here is the idea of running simulations of the past. If our future seems to be one in which simulations of (what is to us) the present will be made, then this suggests that we may be in such a simulation already. Therefore, if we choose to run such simulations, or to make the running of them more likely in the future, we might consider ourselves to be choosing to have been in a computer simulation all along. The backward-causation aspect of this may seem strange, but such ideas are well-known in considerations of Newcomb’s paradox. As well as affecting the probability that you are in a computer simulation, your actions might affect the type of simulation in which you are.






Earth project aims to 'simulate everything'

It could be one of the most ambitious computer projects ever conceived.

An international group of scientists are aiming to create a simulator that can replicate everything happening on Earth - from global weather patterns and the spread of diseases to international financial transactions or congestion on Milton Keynes' roads.

Nicknamed the Living Earth Simulator (LES), the project aims to advance the scientific understanding of what is taking place on the planet, encapsulating the human actions that shape societies and the environmental forces that define the physical world.

"Many problems we have today - including social and economic instabilities, wars, disease spreading - are related to human behaviour, but there is apparently a serious lack of understanding regarding how society and the economy work," says Dr Helbing, of the Swiss Federal Institute of Technology, who chairs the FuturICT project which aims to create the simulator.



Mars Tumbleweed Computer Model Developed

In March, Discovery News had a look at a Mars rover concept that could revolutionize how we carry out planetary exploration.

This rover has no wheels, it's inspired by a bizarre desert plant and its only means of propulsion is the Martian wind. And now, North Carolina State University (NCSU) scientists have designed a computer program to test different designs of the rover before it is even built.

Enter the Mars Tumbleweed Rover, destined to roll where no robot has rolled before.

WIDE ANGLE: Mars is a planet ripe for exploration by mankind. Or is it?

An Exploration Game Changer?

The Mars landscape has so far been dominated by landers and wheeled rovers, and that probably won't change for some time to come. Sure, NASA's current Mars Exploration Rovers are (or "was" in the case of the hibernating Spirit) showing us amazing longevity, but is there another way to traverse Mars? [...]


5 Therapeutic Uses for Virtual Reality

Virtual reality isn’t just for movies and games. In doctors’ offices around the world, it’s being used to treat a range of phobias, disorders and mental and cognitive problems.

Before computer technology matured, therapists would expose patients gradually and in small doses to the object of their phobia, giving them the ability to cope so that in the real world the person could deal with the phobia. But even in small doses, exposure to a fear would overwhelm a patient.

In simulated environments, the patient has control over the situation. [...]
