FMWRC to provide pay-as-you-go internet access Army-wide 090218

FMWRC Public Affairs
Lt. Gen. Robert Wilson, Commanding General, Installation Management Command, asked the Family and MWR Command’s Army Recreational Machine Program to present ideas to improve the quality of life for Soldiers and to generate new sources of income for MWR programs. After a briefing provided by Don Rojas, ARMP General Manager, Lt. Gen. Wilson directed that ARMP “move out” and provision internet services into barracks and other garrison locations to meet the substantial unmet demand for connectivity that Soldiers confronted.
In the two years since those meetings, ARMP has provisioned internet into barracks and other garrison locations at more than 30 garrisons in the continental U.S. and Germany. This is in addition to ARMP’s efforts to provide garrisons the capability to provide free internet support for Wounded Warriors. Provisioning for another handful of garrisons is underway, pending the delivery of circuits and the build-out of the infrastructure needed to carry connectivity to the end user.
Rojas explained that ARMP’s business model is structured to support the Soldier’s lifestyle. Soldiers using FMWRC’s service do not have to sign long-term contracts tying them to vendors who install customer on-premise receiver devices. Instead, they are offered flexible subscription plans permitting hourly, daily, bi-weekly or monthly subscription options.
This model gives Soldiers maximum flexibility based on the unpredictable nature of their training and deployment regimens.
“Soldiers pay only for the internet connectivity that they use which contrasts with traditional vendor delivered services where the customer pays for the internet or cable TV regardless of whether they use it or not,” Rojas said.
“For Soldiers, the ability to connect to the internet in a convenient, no hassle and reliable way becomes a QOL enabler because discretionary time is so precious to our Soldiers,” he added.
The pilot program began at Forts Benning and Gordon in early 2007.
“We found as we began that we had a learning curve to overcome. But we also saw a substantial market with unmet demand, and we had tremendous support from the command and MWR leadership at these installations,” said Rojas.
ARMP returns 35% of gross revenues from all subscriptions directly back to the installation. After operating expenses and depreciation are deducted, all residual profits are deposited into the MWR Trust Fund. This is the central non-appropriated fund where net profits from all ARMP operations and AAFES dividends are deposited to earn interest until they are used to fund major construction projects for MWR activities.
The program was interrupted in December 2007, when ARMP was tasked to provide all Wounded Warriors with personal computers, internet connectivity, phone service, and cable television in all government-provided housing and barracks.
ARMP executed that mission by March 31, 2007 and continues to provide WTU commanders with sustainment and support for our Wounded Warriors. Additionally, ARMP has been tasked to Support Soldier and Family Assistance Centers (SFACs) with their requirements for internet support, computers, printers, and multi media.
Wounded Warriors now receive free internet service at the 40 Warrior Transition Units (WTU) across Germany and the U.S., thanks to funding provided through Army Family and Morale, Welfare and Recreation Command (FMWRC) from the U.S. Army Installation Management Command (IMCOM).
“When we received the mission to support our WTUs, we largely set aside our mission to provision pay-as-you-go internet support to other Soldiers living in barracks and focused all of our resources on support for Wounded Warriors,” Rojas said.
“Once the initial objective was achieved, we transitioned from ramp-up and execution to sustainment for WTUs and reallocated our efforts back to providing connectivity for other Soldiers living in barracks.”
Because of the initial successes with WTU and fee-based internet connectivity, requests from garrisons for support has rapidly grown and expanded into areas beyond barracks and traditional MWR internet cafes. To date, about 50 garrisons in Europe, Asia and the U.S. have been provided commercial internet connectivity. Demand has grown to such an extent that circuits are being upgraded at many of these garrisons. Another dozen or so garrisons have requested support and are awaiting build out.
One of the challenges that MWR programs face is the limitation on the access and use of the military net imposed to protect the network from malicious attacks and electronic penetrations that jeopardize national security. These restrictions limit the abilities of Army libraries, Youth Tech Labs, MWR web pages and other program users to access the internet for legitimate end-user requirements.
As a consequence, ARMP has been working with the Network Enterprise Technology Command and garrison staffs to provide commercial internet connectivity to support these programs that is not dependent on the MILNET.
“We have received tremendous support from many garrison Director of Information Management and Signal Command staffs assisting us with the implementation of commercial network solutions in order to provide connectivity,” Rojas said. “In coordination with these professionals, we ensure that there is no cross-connectivity to any portions of the MILNET.”
Another spinoff of these efforts is supporting Army National Guard Soldiers preparing for deployment at Coalition Operation Locations.
Buildings at COLs are usually modular construction and connectivity to the internet was virtually non-existent. Nevertheless, ARMP has been able to accommodate requests for support. To date, COLs at Forts Riley, Carson, Sill, Hood, Lewis, Stewart, Dix, Bliss and Camp Shelby have been provided with connectivity, and enhancements to service is ongoing. Surveys have been completed at Forts Bragg and McCoy and Camp Atterbury, and provisioning of services will be completed at those locations later this year.
“The effort to support these Soldiers has been particularly fulfilling. Connectivity is a fundamental quality of life enabler for these Warriors,” Rojas said. “It enables them to connect with loved ones and take care of business, practice language skills, and continue with education requirements. The service extends far beyond email and connecting to YouTube and MySpace.”
Camp Shelby in Hattiesburg, Miss., is a perfect example, according to Rojas. At Camp Shelby, there are four COLs. All are “downrange” and miles away from the main post. There is no running potable water or electrical infrastructure. The ARMP worked with the garrison staff and 1st Army staff to provide a temporary solution for the connectivity that involves bringing signal in via satellite and using portable generators for power.
To provide Soldiers with a suitable location, ARMP purchased and installed four classroom trailers and installed student work desks, laptops and a printer so that Soldiers at each COL have an “out of the weather” location to support their needs for internet connectivity.
Using wireless, satellite dishes, or existing fiber or copper cables not being used for other purposes, ARMP engineers solved the problem of connectivity. All that’s left is for the Soldier to sign up for the service with his or her debit or credit card.
As soon as resources permit, the same will be true in barracks and other select locations Army-wide: a debit card and a WiFi-ready computer are all a Solder will need to access the internet.
Maryland Scientists Develop World’s Fastest Program to Find Patterns in Social Networks
Newsdesk Release: newsdesk.umd.edu/bigissues/release.cfm?ArticleID=2187
COLLEGE PARK, Md. – As social networks like Facebook, Flickr, Youtube and Twitter increasingly make it possible to access appropriate information within their networks, a whole host of new applications become possible. For individuals, search engines could better differentiate "friends" and suggest groups with more closely matched interests or concerns. Businesses could search allowed information to offer products or services better matched to customers. And national security and counter-terror analysts, with appropriate court authorization, could look for "groups” of people within social networks that match certain characteristics.
However, a technical obstacle to all of these is the difficulty inherent in being able to find all parts of the social network that match a given query network pattern. This essential first step (called the "subgraph matching" step by computer scientists) is often succeeded by many other application-specific steps. The subgraph matching problem is enormously challenging and has long been known to be computationally very difficult, rising exponentially in complexity with the size of the network increases.
University of Maryland grad student Matthias Broecheler working with Computer Science Professor V.S. Subrahmanian and University of Calabria (Italy) Professor Andrea Pugliese have recently unveiled a new mathematically-based computer program, or algorithm, called COSI (short for "Cloud Oriented Subgraph Identification”) that will support subgraph pattern matching in very large social networks containing hundreds of millions, even billions, of links.
In a paper that has been accepted for presentation at the 2010 Advances in Social Network Analysis and Mining conference to be held in Denmark in August, Broecheler, Pugliese and Subrahmanian leveraged a key insight – it is possible to split the social network into a set of almost independent, relatively small sub-networks, each of which is stored on a computer in a cloud computing cluster in such a way that the probability that a query pattern will need to access two nodes is kept as small as possible. Using knowledge of past queries and a complex set of calculations to compute these probabilities, their paper reports algorithms and experiments to answer social network subgraph pattern matching queries on real-world social network data with 778 million edges (which may denote relationships or connections between individuals) in less than one second. More recent results not contained in the paper are able to efficiently answer queries to social network databases containing over a billion edges.
"These new algorithms for subgraph matching make it practical for the first time to implement many desirable functionalities previously only practical for small networks," said Anil Nerode, who is Goldwin-Smith professor of mathematics and computer science and former director of the Mathematical Sciences Institute at Cornell University. "We can expect a profound influence of these algorithms on extending the capabilities of social networks," said Nerode, who is not involved in the work.
Professor Subrahmanian, one of the inventors, said: "An innovative mix of cloud computing and smart thinking, COSI shows how exact social network pattern matching on complex query patterns can be efficiently implemented. It is a significant advance, not only in answering complex queries over large social networks, but also for answering queries over the Semantic Web. This advance could have a significant impact for individual users of social networks as well as for the national security and business communities and is yet another innovative mix of cloud computing and smart thinking.
"The next challenge for COSI will be to perform matching of similar, but not exact, patterns," he said.

04 A hastily-edited taster from my first studio shoot yesterday, taken at Studio 101 in Deptford. I have wanted to shoot some "proper" portraits for a while and have been toying with the idea of buying a small lighting set-up for home. In reality, we don’t have the space so hiring somewhere for half a day seemed like good way to get a feel for it (and potentially get some shots to promote myself to paying customers; there are a lot of young families in Brockley!).
Given that I don’t really know how to use my hotshoe flashgun properly, working with four lights was a challenge, to say the least. As ever, pictures which looked fabulous on the camera’s 3" lcd screen have all manner of imperfections when viewed on 27" of iMac glory – I guess this is why pro photographers often shoot tethered to a computer. Still, it was a fun and relatively inexpensive morning where I got to hang out with some friends and their kids, and I have learned a lot for next time. Here are my top tips for anyone wanting to give it a go themselves:
1. Buy a light meter and know how to use it, or make sure you get the studio to explain theirs before the person you’re hiring from leaves. I did a bit of research and reading about light placement and measurement before I went, and I took a diagram of a basic portrait studio set-up. The ‘free introduction to studio lighting with every first booking!’ was some mumbled words about turning the brightness up and down on the flashes and not rolling the background out too far if you wanted to avoid a £6 per metre charge for dirtying it. I knew the values I wanted from the different lights but I couldn’t figure out how to measure them, so it was trial and error with the power settings.
2. If you can’t measure the light values, at least check to see whether the lights are all the same power output! Only when I was packing up did I notice that the two lights I had been using to light the background (one either side) were different – 200w to the left, 400w to the right. Result? A much darker area to the left of most shots! This is more pronounced because my key light was coming from the front right of the subject. So despite dialling in the same number on each background light, I was effectively getting twice as much power from the right hand one. Bum.
3. Pay the £6 for some fresh background! Or £12, or £18 – whatever you need to get a pure white, clean floor and wall. At the time I was thinking, "I can sort that out in post." What a fucking ball-ache it is to do! I am not an experienced Photoshop or Lightroom user, and I hate spending loads of time post-producing images. If you’re the same, pay for some new paper.
4. Find a studio which has lights which can keep up with your camera’s frame rate. About 15-20% of my shots were black because the studio flash didn’t refresh in time. I don’t know about these things, so maybe 5fps is too fast for studio shoots; but if you’re trying to shoot a jumping child, you want all the chances you can get.
So, all-in-all a good experience. I can see myself getting more into studio photography. More pics from this set to follow, once I’ve dealt with those backgrounds…
