Sequestration and the real world

The Washington Post had an article on June 30, 2013 titled “They said the sequester would be scary.  Mostly, they were wrong.”  It said the effects were largely mitigated by political means and methods after all.   I just want to say that for us at ATI, the predictions of large cutbacks are mostly correct.  It […]
The Washington Post had an article on June 30, 2013 titled “They said the sequester would be scary.  Mostly, they were wrong.”  It said the effects were largely mitigated by political means and methods after all.  
I just want to say that for us at ATI, the predictions of large cutbacks are mostly correct.  It has had a tremendously adverse effect with attendance at public courses down more than 40 %  People either do not have money for travel and/ or they do not have money for training.  Both training and travel are the first to be cut in a tight budget.  The story that best illustrates this came to me from a gentleman who, along with his colleague, had registered –and paid- to attend one of our courses last winter.  In the eleventh hour they had to withdraw as travel funding was no longer permitted.
  I contacted him when the course was next being held to find out if they might be able to attend this time and the answer was “no”.  He elaborated, “They’ve even stopped cutting the grass (knee high is some places) and our restrooms only get cleaned twice a week.  Sequestration is hurting us badly.”   To this I responded, “Holy cow! Knee high grass.”   He came back with, “We could use a few cows.”  
Please feel free to share your Sequestration story.

Certified Systems Engineers Are In Demand

(RIVA, Md., March 2009) Just as you would not attempt a state bar exam without studying, you should not attempt the CSEP (Certified Systems Engineer Professional) exam without preparation. By taking a preparatory course, you can yield great benefits in performance, stress reduction and overall, greatly improve your chances of passing the exam. While the economy is down, the demand for systems engineers is still growing–but supply is low. Last October, Jitu Desai of IBM said, “The demand for systems engineering management of complex programs is increasing. This is coupled with the new technologies that are entering the marketplace to make it both easier and more difficult to manage. We need new ways of managing design and development activities of major systems. This method includes access to global talent and skills, as well as the marketplace offerings that provide improved methods for collaborating innovations.” To assist you in your career, the Applied Technology Institute (ATI) has added a CSEP preparation course to its curriculum. Systems engineering is a profession, practice and way of doing business that concentrates on the design and application of the whole system to produce a successful product or system. The International Council on Systems Engineering (INCOSE) has established a Professional Certification Program to provide a formal method for recognizing the knowledge and experience of systems engineers. The INCOSE Certified Systems Engineering Professional (CSEP) rating is a more coveted milestone in the career of a systems engineer, demonstrating knowledge, education and experience and is of high value to systems organizations. Test what you know. ATIcourses has posted samples from its CSEP Preparation class on its web site at:www.ATIcourses.com/sampler/CSEP_Preparation_CourseSampler.pdf These materials include information on how to apply successfully for the CSEP, a study plan to pass the CSEP exam, sample questions to assess your skills and a guide to completing your application selected from a full two-day course CSEP Preparation sponsored by the Applied Technology Institute. This two-day course walks you through the CSEP requirements and the INCOSE Handbook Version 3.1 to cover all topics on the CSEP exam. Interactive work and study plans, and sample examination questions will help you to prepare effectively for the exam. Participants complete the course with solid knowledge, a hard copy of the INCOSE Handbook, study plans, and a sample examination. This course is currently scheduled as a public offering at several dates and locations: Your facility can request this course as an on-site presentation. The current schedule includes the following public dates open to all:
Mar 20-21, 2012 Columbia, MD
Apr 20-21, 2012 Orlando, FL
The instructor is Eric Honour, an international consultant and lecturer, who has a 38-year career of complex systems development & operation. He was Founder and former President of INCOSE. He has led the development of 18 major systems, including the Air Combat Maneuvering Instrumentation systems and the Battle Group Passive Horizon Extension System locations.

Drone Fleets: The Countries That Possess Them And Potential For Robotic Wars

Despite some pretty disturbing news on UAV developments that are coming from China and a group of other countries U.S. remains the global leader in development, production and most importantly successful implementation of unmanned aircraft vehicles or drones.  However, there is a lot of speculation regarding the world’s expanding drone fleets and their potential for […]
Despite some pretty disturbing news on UAV developments that are coming from China and a group of other countries U.S. remains the global leader in development, production and most importantly successful implementation of unmanned aircraft vehicles or drones.  However, there is a lot of speculation regarding the world’s expanding drone fleets and their potential for reducing the threshold for going to war.  Here is a list of known facts regarding this sensitive issue.
  1. USA is the main developer and manufacturer (however not exporter) of UAVs.  Near the top of the line, the Predator B, or MQ9-Reaper, manufactured by General Atomics Aeronautical Systems, costs about $10.5 million. By comparison, a single F-22 fighter jet costs about $150 million.
The new smaller models are currently developed.
  • Raytheon Missile Systems is in process of designing a 13lb Small Tactical Munition to be carried by smaller unmanned aircraft like Shadow, TigerShark, Hunter and Viking. The device is around 24 inches long and 4 inches around.
  • Northrop Grumman has come out with the Viper Strike, a gliding,GPS-aided laser-guided variant of the Northrop Grumman Brilliant Anti-Tank (BAT) munition which originally had a combinationacoustic and IR seeker. The Viper Strike is 36 inches long and only 5.5 inches in diameter.
  • Lockheed Martin has releasedthe Scorpion (21.5 inches in length, and 4.25 inches in diameter),which is adaptable to multiple launch platforms, including manned or unmanned systems.
  1. China is constantly increasing it’s development and production as well as export of drones.  At the most recent Zhuhai air show they revealed WJ-600 drone and than two dozen other Chinese models. Little is known about their actual abilities but the speed at which they have been developed highlights how U.S. military successes with drones have changed strategic thinking worldwide and spurred a global rush for unmanned aircraft.
  2. Israel, the second-largest drone manufacturer after the United States, has flown armed models, but few details are available.
  3. India announced this year that it is developing ones that will fire missiles and fly at 30,000 feet.
  4. Russia has shown models of drones with weapons, but there is little evidence that they are operational.
  5. Pakistan has said it plans to obtain armed drones from China, which has already sold the nation ones for surveillance.
  6. Iran last summer unveiled a drone that Iranian President Mahmoud Ahmadinejad called the “ambassador of death” but whose effectiveness is still unproven, according to military analysts.
China’s drone technology hasn’t reached the world’s first-class level, but the Chinese are catching up quickly. This is something we know for sure.

      On Monday, January 10, 2011 ATI staff came in to work to discover that the view out of their windows has changed dramatically.  One of the perks of working at Applied Technology Institute is the expansive views of the Beards Creek and South River.  However, what we saw that morning was entirely different.  The surface of the water was covered in large ice circles 4-6 ft. in diameter. As it turns out, an ice disc, ice circle, or ice pan is a natural phenomenon that occurs in slow moving water in cold climates. Ice circles vary in size but have been reported to be more than 4 metres (13 ft) in diameter. Ice discs form on the outer bends in a river where the accelerating water creates a force called ‘rotational shear’, which breaks off a chunk of ice and twists it around.[5] As the disc rotates, it grinds against surrounding ice — smoothing into a circle. A relatively uncommon phenomenon, one of the earliest recordings is of a slowly revolving disc was spotted on the Mianus River and reported in a 1895 edition of Scientific American. River specialist and geography professor Joe Desloges states that ice pans are “surface slabs of ice that form in the center of a lake or creek, instead of along the water’s edge. As water cools, it releases heat that turns into frazil ice” that can cluster together into a pan-shaped formation. If an ice pan accumulates enough frazil ice and the current remains slow, the pan may transform into a ‘hanging dam’, a heavy block of ice with high ridges low centre.

      Low Frequency Home Noise Continued – Another Expert Opinion – Understand How The Noise Is Getting Into The House

      See the previous post from Carolyn about low frequency noise in her home that bothers her sleep and living. Jim, There may be a question about how the noise is getting into the house, whether by airborne transmission of noise outside or ground borne vibration into the structure of the house with noise radiation due to floor/wall vibration. Carolyn said they hear the noise inside but not outside which would suggest that it is ground borne. Also, there are train tracks in the area that where the locomotives sit idling all night. These could be a source of both airborne noise and ground borne vibration at low frequencies. If the problem involves ground borne transmission then modifying the windows will not do much as the path does not involve transmission through the windows. Also, are the vibration at levels sufficient to be feelable by the inhabitants? It would be good if measurements could be carried out to reliably determine whether the transmission is airborne or ground borne. At a minimum, measurements are needed to monitor actual levels of noise inside and outside the house to determine a frequency spectrum of the noise and to establish a correlation between outside and inside levels when the noise occurs. It would be good also to monitor floor or wall vibration levels along with ground vibration levels outside around the house. These measurements would quantify how the noise is getting into the house as a basis for deciding how best to approach reducing it. The suggestion about adding a second pane to the windows should help if the transmission is airborne and the windows are the weak link in blocking transmission through the outer walls of the house – brick should be heavy enough for the solid walls, leaving the windows and possibly the doors. Dealing with ground borne transmission would be more complicated as decoupling the foundation and structure of the house from ground borne vibration transmission is not easy. In non-engineering terms, have the people been in the house for a while?, is this a new problem that developed recently?? Your wondering about contacting someone in public administration about local noise standards is good. Also, are there neighbors with the same issues that could be brought into the pursuit of a solution? We often have community noise problems where a group of neighbors are involved in seeking solutions with the offending company, who is often willing to pursue a solution to maintain good community relations and may be willing to pay to develop a solution. I would be willing to communicate or talk with Carolyn directly about the problem. We are consultants but would be willing to discuss things in a preliminary fashion. Jim Moore

      Space Solar Power – EADS plans to launch a test satellite with solar panels.

      It is a known fact that alternative energy sources — coal, oil shale, ethanol, wind and ground-based solar — are either of limited potential, very expensive, require huge energy storage systems or harm the environment.

      It is a known fact that alternative energy sources — coal, oil shale, ethanol, wind and ground-based solar — are either of limited potential, very expensive, require huge energy storage systems or harm the environment. There is, however, one potential future energy source that is environmentally friendly, has essentially unlimited potential and can be cost competitive with any renewable source: space solar power.

      A space solar power system would involve building large solar energy collectors in orbit around the Earth. These panels would collect far more energy than land-based units, which are hampered by weather, low angles of the sun in northern climes and, of course, the darkness of night.

      Once collected, the solar energy would be safely beamed to Earth via wireless radio transmission, where it would be received by antennas near cities and other places where large amounts of power are used. The received energy would then be converted to electric power for distribution over the existing grid.

      Watch the 60 minutes video now. ATI’s new course, Theory and Fundamentals of Cyber Warfare is offered January 19-20 in Beltsville, MD. Seats are going quickly.

      Register today to reserve your seat.

      The Applied Technology Institute (ATI) announces a new two-day professional development short course, Theory and Fundamentals of Cyber Warfare, offered to the public on Jan 19-20, 2010 in Beltsville, Maryland. The course is offered in response to the growing need for businesses and military facilities to quickly gain an understanding of cyber threats and institute cyber security defenses. It is targeted especially to DoD analysts, specialists and engineers in security related facilities in the Washington, DC, Virginia and Maryland metro area, which has the largest concentration of DoD national security related facilities in the United States. Those facilities, along with the research and development contractors they work with, are building their resources to tackle the growing need for cyber security experts.

      Cyber Warfare is all over news headlines. World leaders, including the United States, Russia, South Korea and Great Britain, are scrambling to organize against the rapidly increasing varieties of threats such as spyware and malware, spoofing, phishing and botnets that are having devastating effects around the world. Digital intelligence experts have labeled these escalating cyber threats as a “Global Cyber Cold War”.

      The instructor for ATI’s new Theory and Fundamentals of Cyber Warfare course is Albert Kinney, who brings more than 20 years of experience in research and operational cyberspace mission areas including the initial development and first operational employment of the Naval Cyber Attack Team. Kinney says, “ I designed the course to focus on providing a top-down view of both the challenges and opportunities encountered in this new warfare domain. Attendees will gain insight to emerging requirements and trends affecting the implementation of cyber warfare systems, policy, and operations that will inform your strategy and focus your efforts in cyberspace.”

      Maryland Governor, Martin O’Malley, was recently interviewed on 103.5 FM WTOP radio identifying Maryland as the next, “silicon valley” of cyber security. “Cyberspace has emerged as a mainstream warfare domain on par with air, land, sea, and space domains. This advancement to a bona fide battle space arises from the de facto behaviors of entities ranging from international superpowers to improvised non-state organizations. As a result, government and military organizations are developing new doctrines, establishing domain-focused operational hierarchies, and acquiring new systems capabilities to maintain cyberspace as a viable resource serving the national interest,” Kinney explains.

      The topic of cyber security first gained momentum when President Obama announced in May that his administration will pursue a plan to secure America’s digital infrastructure and that, “Protecting this infrastructure will be a national security priority.” The President’s plan will involve nearly all sectors of local and national government and military.

      New ATI Course Demystifies Satellite Service Requirements for Government Agencies

      (September, 2009, Riva Maryland) The Applied Technology Institute (ATIcourses.com) has introduced a new three-day short-course, Communications Payload Design–Satellite System Architecture, scheduled Nov 10-12, 2009 in Beltsville, MD.

      (September, 2009, Riva Maryland) The Applied Technology Institute (ATIcourses.com) has introduced a new three-day short-course, Communications Payload Design–Satellite System Architecture, scheduled Nov 10-12, 2009 in Beltsville, MD. The new course is apropos to the U.S. Federal Government’s recent announcement that they will be appropriating $5 billion for the Federal Commercial Satellite Communications Service Acquisition (FCSA) program. The FCSA program will replace several existing programs, streamlining satellite service acquisitions by allowing government agencies access to a wider choice of vendors, services and products, while speeding up the overall procurement process.

      Satellite Communications expert, Bruce R. Elbert, with forty years of combined experience designing satellite communications payload and systems for COMSAT Laboratories and Hughes Electronics, will lead the course, which he says will be essential for government agencies. “Effective satellite communication depends on a clear understanding of the user requirements, including what information is to be communicated, where it must be communicated, and finally, how the unique situation of the user can be addressed (things such as whether the user is stationary or in motion on the ground, in the air or on the sea). There are a myriad of questions to be answered but there are solutions on the market that can potentially address them. Getting through this maze requires a good understanding of the alternative satellite capabilities, kinds of user terminals available, network architectures, and systems engineering processes.”

      The Communications Payload Design–Satellite System Architecture course is designed to outline in detail the technical characteristics of a wide variety of satellites operating in different frequency bands, exploring the advantages and limitations of each, such as Lockheed Martin’s, Advanced Extremely High Frequency (AEHF) satellite. Elbert demonstrates this point explaining, “The military relies on mobility to extend and conduct operations in a wide variety of places. The system provided by Inmarsat would seem to be ideal because the user antennas are small and the network service is quite versatile, being IP based. However, the bandwidth afforded is low relative to many requirements and the cost per MByte is quite high as compared to, say, Ku band satellite services. Alternatively, Ku band is very popular because it addresses these issues, but the availability of Ku satellites is somewhat less and the attendant user antennas tend to be much larger. They also must be pointed rather accurately at the particular satellite in use, a challenge for moving vehicles,” he says.

      Prospective end-users of the course are not limited to military and government audiences. It also provides knowledge and methodologies to use satellite communications for non-government applications in field such as oil and gas exploration and production, emergency management, transportation and broadcasting.

      War Over The Whales: The Navy insists underwater warfare range won’t hurt rare right whales off Florida coast

      Miami Herald September 10, 2009 By Curtis Morgan Every winter endangered North Atlantic right whales migrate to warm, shallow waters to give birth and nurse their young. That’s right next to where the U.S. Navy wants to conduct antisubmarine training. Florida isn’t known for whale watching, but every winter the coastline offers a haven for endangered North Atlantic right whales. They migrate to warm, shallow waters to give birth and nurse little — relatively speaking — one-ton bundles of blubber. That’s right next to where the U.S. Navy wants to conduct antisubmarine training. The Navy has selected a site bordering a federally protected whale nursery stretching from Savannah to Sebastian for an undersea warfare range, where ships, submarines and aircraft outfitted with powerful sonar can practice hunting subs. Citing voluminous studies, the Navy concluded that training 58 miles off Jacksonville would rarely, and barely, disturb right whales. Environmentalists say the Navy has soft-pedaled risks from the 500-square-mile range. Ship strikes already rank as the top right whale killer. The Navy also intends to heavily employ sonar that can disrupt feeding and communication, cause hearing damage and — in extreme cases — trigger mass strandings such as one in the Bahamas that killed six beaked whales in 2000. “It’s one of the worst possible places,” said Catherine Wannamaker, an attorney for the Southern Environmental Law Center, one of 21 groups that contested the choice. “It’s right next to the calving grounds for one of the rarest whales in the world.” The groups contend that the range poses a disruptive, potentially deadly threat to a whale population numbering no more than 400 — and that’s after producing 39 calves last year, the most in decades. Florida and Georgia environmental regulators have raised similar concerns. Navy is moving ahead because Florida’s location and logistics beat sites off South Carolina, North Carolina and Maryland. Jacksonville boasts a seaport, air base and submarine base across the St. Mary’s River in King’s Bay, Ga. The Navy already has a deep-water sonar range in the Bahamas, but Julie Ripley, the Navy’s environmental spokeswoman, said the shallow sea floor and busy shipping lanes off northeast Florida provide a real-world test for sonar operators who must pinpoint a new generation of stealthier subs. Environmentalists, who have been battling the Navy for years over sonar, argue that it’s the whales that are perishable. Though there are signs of slow recovery, scientists consider their future precarious. The whales take a decade to hit sexual maturity. Females produce one calf a year, so losing one prematurely can set back recovery. Ship strikes are such a serious concern — 22 whales were hit between 1999 and 2006, with 13 confirmed deaths — that the fisheries service last year imposed seasonal zones limiting large vessels to 10 knots in whale habitat. The Navy — involved in roughly one-sixth of 134 documented strikes over 60 years — was exempted. Factoring in total sea hours, the service calculated the chance of any Navy ship hitting a whale in any year at .0000472 percent. The chances of not doing it: 99.99 percent. While whales have been spotted 60 miles out where the range is planned, past surveys — which environmentalists consider inadequate — suggest that most swim relatively close to shore, some 30 miles from where the Navy plans to train. The Navy, which adopted whale-avoidance policies in 2002, also has proposed more precautions during calving season — posted lookouts, daytime training and exercising “extreme caution” in ship speed and sonar power. But environmentalists remain skeptical, pointing to a series of strikes that have killed whales since 2000, including six pregnant females. Then there is the complex question of sonar. For the Navy, it’s critical protection for military vessels and shipping lanes — particularly mid-frequency active systems that emit “pings” of powerful sound, measuring echoes to identify and track targets. There is no dispute that active sonar can disturb whales and dolphins. They rely on echolocation, their own internal sonar, to navigate and hunt, and use an array of calls or “songs” to communicate. But research — much of it bankrolled by $20 million a year from the Navy — shows widely varying impacts, depending on species and sonar levels. Animals can leave an area, possibly under stress, or abandon feeding or breeding. Some studies indicate that repeated exposure can cause temporary hearing loss. In the worst cases, fleeing whales and dolphins beach in mass, often fatal, strandings. The Navy, in a 2001 study after 17 whales and a dolphin beached in the Bahamas, acknowledged that its mid-frequency sonar played a role, but also pointed to an unusual confluence of other factors. Necropsies of whales that beached in the Canary Islands in 2002 during international naval exercises showed brain hemorrhages, vascular ruptures and lung congestion. One theory is that they bolt from depths so quickly their organs can’t handle rapid pressure changes — akin to the “bends,” or embolisms that divers suffer when surfacing too quickly. As a concession to state concerns, the Navy agreed not to lay fiber-optic cable and transducers during calving season, which runs from mid-November to mid-April. Wannamaker said it would resolve many concerns if the Navy made the same pledge for sonar training. The Navy responded that option has “been given consideration” but that they want to retain “flexibility.” Wannamaker said the groups are pondering a lawsuit, not trusting that more studies and surveys will sway the final decision. “Once you build a $100 million project,” she said, “nobody is going to tell them they can’t use it.” Full story here.
