Conceptual Modeling Corner in the SCS M&S Magazine (by Bill Waite)

Dr. Lou Birta, Professor Emeritus at the University of Ottawa, publishes “M&S Magazine” on behalf of the Society for Modeling and Simulation International. Dr. Birta has a longstanding interest in simulation conceptual modeling; and he is proceeding to add a feature denoted:  “Conceptual Modeling Corner” as a component of future issues of M&S Magazine.

As he has indicated in the Editorial Page of the July issue; the intent of this initiative is to generate some lively discussion and debate in future issues of the M&S Magazine about the nature and intent of a conceptual model.

In order to stimulate discussion, he has posited a ‘sample-problem’ outlined in the July issue of the M&S Magazine; and he wishes to solicit from members of the M&S community of practice contributions of a commensurate conceptual model. Please consider Dr. Brita’s invitation to review his ‘sample problem’ and contribute commentary relevant to realizing a representative conceptual model suitable for publication in future issues of the magazine’s “Conceptual Modeling Corner” feature.


Modeling & Simulation technology can enhance military readiness (from SimSummit Executive Committee)

Please see the link to testimony invited by Representative J. Randy Forbes provided to the House Armed Services Readiness Subcommittee hearing on “how Modeling and Simulation technology can enhance military readiness”.

Record of the testimony, including a statement by RADM Fred Lewis of NTSA, a SimSummit Member-Sponsor organization, is available by clicking here.

This transaction indicates the interest of the U. S. House of Representatives M&S Caucus in the value of M&S; and the testimony regarding particular significance of M&S to military readiness is suggestive of the myriad ways M&S as a “critical technology” contributes to security and economic welfare in the U.S. and around the world.


How to create a 'super password'

The 12-character era of online security is upon us, according to a report published this week by the Georgia Institute of Technology. The researchers used clusters of graphics cards to crack eight-character passwords in less than two hours. But when the researchers applied that same processing power to 12-character passwords, they found it would take 17,134 years to make them snap. "The length of your password in some cases can dictate the vulnerability," said Joshua Davis, a research scientist at the Georgia Tech Research Institute. It's hard to say what will happen in the future, but for now, 12-character passwords should be the standard, said Richard Boyd, a senior research scientist who also worked on the project. [...]


An Attempt to Generalize AI - Part 19: Wish-Fulfillment in Action Selection

This is the nineteenth in a series of articles attempting an overview of how minds may work and how similar systems could be implemented in computers. The model is supposed to do most of the planning, projecting the system’s behavioral history into the future, but there is no history of competence to start with and noise would also cause problems.




To establish an appropriate behavioral history, an action selection process is needed to act externally on the system and push behavior slightly in the preferred direction.

The action selection process is now being changed and the new process is described. The new action selection process involves artificially and modestly increasing a predicted evaluation function score so that the model will produce a narrative which tends to result in that higher score. Some of this narrative will involve good luck, but some of it will involve improved behavior. [...]


The AERIA \ Fulfilling the Vision

The AERIA technology vision from Presagis brings together COTS software into an open, scalable, and reusable modeling & simulation development workflow.

The key enabling technologies behind Aeria are leading industry simulation and communication standards including OpenFlight, Terrapage, Common Database (CDB), OTF, CTDB, JCATS, and the GIS data format.

This standards-based approach ensures:

· Complete integration between all Presagis tools and 3rd party applications

· Reusability of data across multiple projects

By enabling users to choose from a wide variety of applications, standards, and formats, and by providing the ability to connect disparate simulation systems, Aeria is a unique space for the development of open, scalable, end-to-end modeling and simulation applications.

The Simaviatik Cockpit (from SimHQ website)

Aviation exhibitions are funny places. One never knows what hidden treasure lies buried in one of those vast exhibition halls. The exhibition was Aero 2010 in Friedrichshafen. Friedrichshafen is a small town on the shores of Lake Constance, peculiar, yet wonderful place, with three countries mixing their borders in different combinations (Germany, Austria and Switzerland).

Aero Friedrichshafen is a major European show for general aviation — from hang gliders and light aircraft, to majestic business jets of all kinds and sizes. Diamond was also displaying their new flight simulator for the DA-42, which of course was tried and tested, but this toy is out of range of the average simmer, and besides — it is not meant for fun, but for serious training work.

In one of the neighboring halls (which by the way, had the motif of giant aviation hangars), there was another company, exhibiting something, which, in sharp contrast with Diamond’s offering would actually be within shooting range of — let’s put it this way — the enthusiast flight simmer.

SimAviatik is a Swiss company specializing in low-cost simulators, aircraft shells (not real ones of course, simulator shells), 2, 3 and 6 DOF platforms, different components of hardware for simulator consoles such as yokes, rudders, instrument panels, and throttles. Long story short — everything a simmer would need to build a sim cockpit. But at Aero 2010 they were not exhibiting A320 or B737 cockpits, they were showing cockpits for the “a sim without shooting is no sim” crowd. They were showing their P-51 and Bf-109 cockpits! [...]
