“Hi diddle diddle,
The cat and the fiddle,
The cow jumped over the moon.
The little dog laughed,
To see such fun,
And the dish ran away with the spoon.”
My mother taught me that playful English nursery rhyme when I was about nine years old..
Notice how the poet who wrote it couldn’t think of anything more fanciful than having a living,
breathing creature ending up in the vicinity of the moon!
It took 300,000 of us a full decade of very hard work, but we did it! We sent two dozen
astronauts on the adventure of a lifetime and we brought all of them back alive. In 1961
President John F. Kennedy, youthful and exuberant and brimming over with confidence,
announced to the world that America’s scientists and engineers would—within a single decade
—land a man on the moon and return him safely to the earth. No cows need apply. But
potential human astronauts were bigly and hugely enthusiastic about their new opportunity
to fly through space to a different world.
By using the math and physics we had learned in school, we covered hundreds of pages with
with cryptic mathematical symbols to work out the details down to a gnat’s eyebrow.
We ended up hurling 24 American astronauts into the vicinity of the moon!. 12 of them
“kangaroo hopped“ on its surface.
Earlier this month, when the moon grew to its maximum apparent size, we were all reminded of
the excitement we felt during Project Apollo. Of course, the size of the moon did not actually
change, it merely moved up to its point of closest approach.
Systematic perturbations on the moon’s orbit coupled with rhythmic variations in its distance
from the Earth as it traveled around its elliptical orbit resulted in surprisingly large variations
in its apparent size and its brightness as seen from the Earth.
These distance variations, in turn, cause its observed diameter and its brightness to vary by as
much as 15 and 30 percent, respectively. When the moon approaches its maximum apparent
size and brightness, it is characterized as a supermoon. The biggest and brightest supermoons
are spaced out several decades apart.
My son, Chad, who participates in Special Olympics, used his cellphone camera to create the
two photographs that accompany this blog. He took the first picture at the crack of dawn
when the moon reached its maximum diameter at the edge of the parking lot at the Embassy
Suites Hotel in Lexington, Kentucky (population 360,000). He made the second photograph
12 hours later in my hometown of Springfield, Kentucky, ((population 2900). That second
picture was made on a small roadside hill beside the Bardstown Road above the IGA
Supermarket within sight of the yellow blinker light at the edge of town.

The Washington Post had an article on June 30, 2013 titled “They said the sequester would be scary.

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.
ATI, a leader in scientific and technical training since 1984, will be hosting the course. ATI specializes in training seminars for professionals working in radar, sonar, space systems, satellites and systems engineering.

ATI’S MILITARY STANDARD 810G (MIL-STD-810G) TESTING COURSE
The course emphasizes topics you will use immediately. Suppliers to the military services protectively install commercial-off-the-shelf (COTS) equipment in our flight and land vehicles and in shipboard locations where vibration and shock can be severe
This four-day class will provide education in the purpose of each test, the equipment required to perform each test, and the methodology to correctly apply the specified test environments. Vibration and Shock methods will be covered together and will include an overview of Sine and Random Vibration as well as classical waveform shock testing, drop testing and Shock Response Spectrum Testing. Instrumentation, vibration equipment, control systems and fixture design will be covered.
Each climatic test will be discussed individually, focusing on requirements, origination, equipment required, test methodology and understanding of results. Class members will participate in a tour of a lab that daily performs the full spectrum of 810G tests. Class discussion will be supported by projected visuals and video clips.
Commencing with a review of basic vibrations, we will explore vibration measurements and analysis. We’ll compare sinusoidal vs. random vibration testing systems, specifications, standards and procedures. We will emphasize vibration and shock test fixture design, fabrication, experimental evaluation and usage. We will study shock measurement, shock response spectrum (SRS) and shock testing.
Climatic testing will be looked at in great detail, emphasizing required equipment and instrumentation, correct interpretation of specifications and hints to ensure that the tests are brought to a successful conclusion. We laboratory test the protected equipment (1) to assure twenty years equipment survival and possible combat, also (2) to meet commercial test standards, IEC documents, military standards such as STANAG or MIL-STD-810G, etc.
What you will learn:
• perform vibration, shock and climatic tests
• evaluate and select equipment to perform testing
• convert field measured data into a test program,
• interpret vibration and shock test requirements and results,
• supervise vibration, shock and climatic tests,
• specify and experimentally evaluate vibration and shock test fixtures
When you visit a test lab or review a test program, you will have a good understanding of the requirements and execution of dynamics and climatics tests and so be able to ask meaningful questions and understand laboratory personnel responses.
If you are in need of more technical training, then boost your career with the knowledge needed to provide better, faster, and cheaper solutions for sophisticated DoD and NASA systems. Why not take a short course instead?

The Australian Research Centre for Aerospace Automation’s (ARCAA) Smart Skies project, focusing on the development of technology to enable manned and unmanned aircraft to effectively share airspace, is approaching its final milestone.
The project, also involving Boeing Research and Technology-Australia, Insitu Pacific and the Queensland Government, is exploring development of three key enabling aviation technologies: an Automated Separation Management System capable of providing separation assurance in complex airspace environments; Sense and Act systems for manned and unmanned aircraft capable of collision avoidance of dynamic and static obstacles; and a Mobile Aircraft Tracking System (MATS) utilising a cost-effective radar and dependent surveillance systems.
The latest flight trials included all of the project elements, including a fixed-wing UAV and a modified Cessna flying in automatic mode, flying collision scenarios with simulated aircraft.
The final flight trial will take place in December this year, before project wrap-up and final reports in 2011, and, ultimately, the attempt to commercialise the Smart Skies intellectual property.
ARCAA acting director Dr Jonathon Roberts said a new research project was also on the cards. The collision-avoidance research is one of two key areas in which the Civil Aviation Safety Authority (CASA) requires proof that technology in unmanned aircraft can operate in a way equivalent to human pilots.
“In the future research we’re trying to hit the next problem: Smart Skies is all about collision avoidance and managing the avoidance of collisions; the next thing that CASA will require will be automatic landing systems,” Dr Roberts said. “So that if you have an engine failure or other catastrophic failure and you have to come down, you’ve got to be able to put it down in a safe place, so these will be vision systems that actually look at the ground and figure out where to land.
“That’s the next thing that has to be done before UAVs can fly over populous areas.”
The Smart Skies program was recently recognised at the Queensland Engineering Excellence Awards, where it won the ‘Control systems, networks, information processing and telecommunications’ category.

Lowrance announced today the premier of its next-generation sonar technology, the LSS-1 StructureScan(TM) sonar imaging module for Lowrance High Definition Systems (HDS), at ICAST 2009 in Orlando, Florida. Raising the bar in fish-finding technology, the sonar-imaging module is the world’s first to offer anglers a new dimension in underwater picture-like displays – side-to-side plus straight down, full panoramic viewing.
The innovative Lowrance StructureScan features a combination of SideScan and an exclusive new DownScan Imaging(TM) technology. SideScan provides full-screen left and right side-viewing with extra-crisp detail of up to 480 ft. (146 m) of underwater coverage that displays structure and fish targets, as well as their imaging-scan shadows. The new DownScan Imaging feature allows anglers, for the first time, to see submerged detail directly beneath their boats, providing a complete underwater picture in a screen format that is easy to interpret. With revolutionary on-screen display versatility, anglers can merge Lowrance side and down sonar scans in split-screen to view wide-area surveys and highly-defined detail. As a unique new tool, anglers can also compare DownScan Imaging with 2D sonar images in split-screen display to better distinguish fish from structure. Removing all of the guesswork common to existing fish-finding technology, the new LSS-1 delivers the highest underwater definition ever achieved with crystal-clear views in shallow and deep, freshwater or saltwater – even at speeds up to 30 mph.

“Hi diddle diddle,
The cat and the fiddle,
The cow jumped over the moon.
The little dog laughed,
To see such fun,
And the dish ran away with the spoon.”
My mother taught me that playful English nursery rhyme when I was about nine years old..
Notice how the poet who wrote it couldn’t think of anything more fanciful than having a living,
breathing creature ending up in the vicinity of the moon!
It took 300,000 of us a full decade of very hard work, but we did it! We sent two dozen
astronauts on the adventure of a lifetime and we brought all of them back alive. In 1961
President John F. Kennedy, youthful and exuberant and brimming over with confidence,
announced to the world that America’s scientists and engineers would—within a single decade
—land a man on the moon and return him safely to the earth. No cows need apply. But
potential human astronauts were bigly and hugely enthusiastic about their new opportunity
to fly through space to a different world.
By using the math and physics we had learned in school, we covered hundreds of pages with
with cryptic mathematical symbols to work out the details down to a gnat’s eyebrow.
We ended up hurling 24 American astronauts into the vicinity of the moon!. 12 of them
“kangaroo hopped“ on its surface.
Earlier this month, when the moon grew to its maximum apparent size, we were all reminded of
the excitement we felt during Project Apollo. Of course, the size of the moon did not actually
change, it merely moved up to its point of closest approach.
Systematic perturbations on the moon’s orbit coupled with rhythmic variations in its distance
from the Earth as it traveled around its elliptical orbit resulted in surprisingly large variations
in its apparent size and its brightness as seen from the Earth.
These distance variations, in turn, cause its observed diameter and its brightness to vary by as
much as 15 and 30 percent, respectively. When the moon approaches its maximum apparent
size and brightness, it is characterized as a supermoon. The biggest and brightest supermoons
are spaced out several decades apart.
My son, Chad, who participates in Special Olympics, used his cellphone camera to create the
two photographs that accompany this blog. He took the first picture at the crack of dawn
when the moon reached its maximum diameter at the edge of the parking lot at the Embassy
Suites Hotel in Lexington, Kentucky (population 360,000). He made the second photograph
12 hours later in my hometown of Springfield, Kentucky, ((population 2900). That second
picture was made on a small roadside hill beside the Bardstown Road above the IGA
Supermarket within sight of the yellow blinker light at the edge of town.

and Orbital Mechanics short course for The Applied Technology Institute. Click here for more
