Georgetown University School of Foreign Service in Qatar held a conflict resolution and negotiation simulation titled “Afghanistan in 2015: Chaos in Kabul.” The simulation, organized in conjunction with Georgetown’s Institute for the Study of Diplomacy (ISD) in Washington, D.C., included 25 student participants from the Georgetown Qatar and D.C. campuses, the Academic Bridge Program, as well as local high school students. Canadian Head of Mission to Qatar, Gary Luton, played the role of UN Secretary General in the exercise.
“It’s always useful for practitioners to engage with students on important issues, and to hear their opinions on and reactions to some of the international community’s most vital concerns,” said Luton.
The exercise, a blend of real-world events and fictional elements that help facilitate learning objectives, was designed to help students think about and experience domestic and international efforts towards reconstruction and development after international military forces have pulled out of a country, the power struggle within Afghanistan in particular, and how the UN, foreign governments, the Afghan government, tribal leaders and the Taliban can interact constructively.
Students received a set of “confidential” instructions outlining each team’s initial position on developing a road map for Afghan reconstruction and development several days before the simulation began. During the simulation, students engaged in a series of bilateral and multilateral meetings which culminated in a final session presided by the UN Secretary General, played by the Canadian Head of Mission to Qatar, Gary Luton.
“The value of simulations for students studying international affairs, is that they get to immerse themselves in very difficult topics and learn about the subject matter. They then get to play the role of the people in the real world who are trying to do something about that crisis,” said Jim Seevers, the ISD’s Director of Studies and Training who created the exercise in conjunction with ISD Associate Lt. Colonel Mike Shortsleeve. “The students love the process of actually being the negotiator. When you’re being asked, not just to understand a subject, but to negotiate with a party that you know has a different view, you begin to see issues from different parties’ perspectives,” added Seevers.
During the exercise, students formed several teams representing the Islamic Republic of Afghanistan, the Taliban, the Islamic Republic of Iran, the Islamic Republic of Pakistan, the United States, the People’s Republic of China, and the U.N. Assistance Mission in Afghanistan. A “control room” of faculty and policy practitioners played the role of the Afghan Tribal Leaders and ISAF/NATO.
Ysa Chandna, a Georgetown University student, commented, “Crisis Simulation is perhaps the best thing at Georgetown University; this is my third time taking part in it and I’m very glad I did because I learned a lot from it.”.

Kuiper belt: ...is a region of the Solar System beyond the planets extending from the orbit of Neptune (at 30 AU [Astronomical units]) to approximately 55 AU from the Sun. It is similar to the asteroid belt, although it is far larger—20 times as wide and 20–200 times as massive. Like the asteroid belt, it consists mainly of small bodies, or remnants from the Solar System's formation. While the asteroid belt is composed primarily of rock and metal, the Kuiper belt objects are composed largely of frozen volatiles (termed "ices"), such as methane, ammonia and water. It is home to at least three dwarf planets – Pluto, Haumea and Makemake.
Scattered disc: ...is a distant region of the Solar System that is sparsely populated by icy minor planets, a subset of the broader family of trans-Neptunian objects. The scattered disc objects have orbital eccentricities ranging as high as 0.8, inclinations as high as 40°, and perihelia greater than 30 astronomical units. These extreme orbits are believed to be the result of gravitational "scattering" by the gas giants, and the objects continue to be subject to perturbation by the planet Neptune. While the nearest distance to the Sun approached by scattered objects is about 30–35 AU, their orbits can extend well beyond 100 AU. This makes scattered objects "among the most distant and cold objects in the Solar System". The innermost portion of the scattered disc overlaps with a torus-shaped region of orbiting objects known as the Kuiper belt, but its outer limits reach much farther away from the Sun and farther above and below the ecliptic than the belt proper.
Because of its unstable nature, astronomers now consider the scattered disc to be the place of origin for most periodic comets observed in the Solar System...
Formation of the Kuiper belt and Scattered disc?: The scattered disc is still poorly understood: no model of the formation of the Kuiper belt and the scattered disc has yet been proposed that explains all their observed properties.
According to contemporary models, the scattered disc formed when Kuiper belt objects (KBOs) were "scattered" into eccentric and inclined orbits by gravitational interaction with Neptune and the other outer planets. The amount of time for this process to occur remains uncertain. One hypothesis estimates a period equal to the entire age of the Solar System; a second posits that the scattering took place relatively quickly, during Neptune's early migration epoch.
Models for a continuous formation throughout the age of the Solar System illustrate that at weak resonances within the Kuiper belt (such as 5:7 or 8:1), or at the boundaries of stronger resonances, objects can develop weak orbital instabilities over millions of years. The 4:7 resonance in particular has large instability. KBOs can also be shifted into unstable orbits by close passage of massive objects, or through collisions. Over time, the scattered disc would gradually form from these isolated events...Modern theories indicate that neither Uranus nor Neptune could have formed in situ beyond Saturn, as too little primordial matter existed at that range to produce objects of such high mass. Instead, these planets, and Saturn, may have formed closer to Jupiter, but were flung outwards during the early evolution of the Solar System, perhaps through exchanges of angular momentum with scattered objects. Once the orbits of Jupiter and Saturn shifted to a 2:1 resonance (two Jupiter orbits for each orbit of Saturn), their combined gravitational pull disrupted the orbits of Uranus and Neptune, sending Neptune into the temporary "chaos" of the proto-Kuiper belt. As Neptune traveled outward, it scattered many trans-Neptunian objects into higher and more eccentric orbits... - enWikipedia
This is how I see Machine To Keep A Feather In The Air working (if it works at all). The simulation is not that accurate of course, and there is a lot more code that needs to go into it still, the outer fans should do more to keep the balloon in the middle for instance.
The idea is that the "balloon" here will later be replaced by a vision system that tracks the object in real life and passes the information along to the simulation, some of the same rules should apply with tuning that system, such as for instance "don't blow on the object if it is moving upwards" and "ignore the object unless it is below a certain height".
Also, I'll be wanting to use as few (pan/tilt servo pairs + fan) as possible, 5 seems like a good number.

These are reference images I'm using to test my new Velvia 100 RVP Film Simulation presets.
It's pretty well nailed down. With DMAX increases to Greens and Reds, and careful attention to how Velvia F used to make Reds orange and Yellows green, I made the adjustsments to reflect with known parameters of Velvia 100 RVP.
Like RVP, lighting conditions, exposures and subjects work differently with this simulation, but I used this reference set of 16 images to really stress test the preset.
In some cases, only two of the sliders need to be adjusted to suit the shooting conditions which are Exposure and White settings.
White balance needs to be adjusted manually. RVP tends to have a coolish tendency to it's images (which kind of makes sense because projector lights tended to be warmer.
White balancing with this preset requires you find your optimal results and then pull back towards cool just a little bit.

Day 10 of the 2012 Advanced Science Course 'Around the World and Around the Clock: The Science and Technology of the CTBT'. Participants engaged in an On-site inspection table-top-exercise.
CAMP ITAMI, Japan - Yama Sakura 69 stands as the latest iteration of one of the world’s largest bilateral command post exercises. More than a 1,000 American and Japanese service members stationed throughout the Pacific implement cutting edge technology to fight a fictitious foe threatening Japan’s sovereignty.
As sophisticated computer programs project scores of simulated battles on hundreds of screens, a small yet expertly trained group of U.S. Army Soldiers, Japan Ground Self-Defense Force (JGSDF) service members and Department of Defense civilians maintain and monitor a cohesive network that connects two Armies training across thousands of square miles.
Led by U.S. Army Japan, YS 69’s G6 section coordinates with its JGSDF counterparts to develop a reliable system that produces realistic training simulations while simultaneously establishing thousands of communication links that enable the countless phone calls, email messages and video teleconferences necessary to establish command and control of the virtual battlefield.
Since the team’s arrival in mid-November, G6 has overcome a myriad of challenges from internet connectivity to live video streaming to create a common operating picture that demonstrates the empowering partnership between the U.S. Army and JGSDF. Many members of the team will remain in Camp Itami in the days after the exercise's conclusion to repack equipment and reconfigure networks.
