Training budgets: Smaller is not an option
Posted by Val in Acoustics & Sonar, Analysis and Signal Processing, Continuing Education and Seminar Marketing, Defense, Including Radar, Missiles and EW, ENGINEERING, General, GPS Technology, Satellites, Space and Satellites, Systems Engineering & Project Management, Systems Engineering and Project Management, Underwater Acoustics and Sonar, Unmanned Aerial Systems (UAS) or Unmanned Aerial Vehicles (UAV) on February 6, 2013
The debate on the budgets for the government organizations is pretty toxic in the US. Both US Navy and US Army alongside other organizations have declared budget shortfalls which effect many areas including training. Without commitment to training and learning new skills there can be no continuous improvement, which is one of the prime directives of any government or company.
The Applied Technology Institute (ATI) specializes in short course technical training in space, communications, defense, sonar, radar, systems engineering and signal processing. Since 1984 ATI has provided leading-edge public courses and on-site technical training to defense and NASA facilities, as well as DOD and aerospace contractors. The courses provide a clear understanding of the fundamental principles and a working knowledge of current technology and applications.
When your company does not want to pay for the training you really want, as an alternative, you can:
- Spent your own personal money and funds; if you believe in it and then you will do it
- Find a user group who are practicing the skills you desire
- Don’t accept the classic answer from the boss, “How does X help the business?”. If the training is relevant to you achieving a goal of being a much better employee then of course it is relevant.
- Find another organization to work for
A training manager with a good team can:
- Fight for your team and their training; fight for your team’s budget and don’t let the senior management take it away
- Give up your personal training for the entire year and suggest that they allocate the extra budget to training for your team members
- Perhaps, it is time to evaluate the relationship with the preferred supplier of training. Has your firm been getting decent value from the PSL (preferred supplier list)?
- Find alternatives to training like brown bag lunches and/or collaborate with other businesses
Everybody needs training and self-improvement.

ATI’s Top 5 Engineering Course Samplers of 2011
Posted by admin in Acoustics & Sonar, Analysis and Signal Processing, Defense, Including Radar, Missiles and EW, ENGINEERING, Space and Satellites, Systems Engineering and Project Management on February 1, 2012
What Are the Tools of Your Trade?
Our mission here at the Applied Technology Institute (ATI) is to provide expert training and the highest quality professional development in space, communications, defense, sonar, radar, and signal processing. We are not a one-size-fits-all educational facility. Our short classes include both introductory and advanced courses.
ATI’s Top Five Engineering Courses for 2011
The five engineering courses for 2011 are highlighted below:
#1 Practical Statistical Signal Processing – using MATLAB
This 4-day course covers signal processing systems for radar, sonar, communications, speech, imaging and other applications based on state-of-the-art computer algorithms. These algorithms include important tasks such as data simulation, parameter estimation, filtering, interpolation, detection, spectral analysis, beamforming, classification, and tracking. Until now these algorithms could only be learned by reading the latest technical journals. This course will take the mystery out of these designs by introducing the algorithms with a minimum of mathematics and illustrating the key ideas via numerous examples using MATLAB.
Designed for engineers, scientists, and other professionals who wish to study the practice of statistical signal processing without the headaches, this course will make extensive use of hands-on MATLAB implementations and demonstrations. Attendees will receive a suite of software source code and are encouraged to bring their own laptops to follow along with the demonstrations.
#2 Advanced Topics in Digital Signal Processing
This four-day course is designed for communication systems engineers, programmers, implementers and managers who need to understand current practice and next generation DSP techniques for upcoming communication systems. DSP is more than mapping legacy analog designs to a DSP implementation. To avoid compromise solution appropriate for an earlier time period, we return to first principles to learn how to apply new technology capabilities to the design of next generation communication systems.
#3 Engineering Systems Modeling WithExcel/VBA
This two-day course is for engineers, scientists, and others interested in developing custom engineering system models. Principles and practices are established for creating integrated models using Excel and its built-in programming environment, Visual Basic for Applications (VBA). Real-world techniques and tips not found in any other course, book, or other resource are revealed. Step-bystep implementation, instructor-led interactive examples, and integrated participant exercises solidify the concepts introduced. Application examples are demonstrated from the instructor’s experience in unmanned underwater vehicles, LEO spacecraft, cryogenic propulsion systems, aerospace & military power systems, avionics thermal management, and other projects.
#4 Wavelets: A Conceptual, Practical Approach
Fast Fourier Transforms (FFT) are in wide use and work very well if your signal stays at a constant frequency (“stationary”). But if the signal could vary, have pulses, “blips” or any other kind of interesting behavior then you need Wavelets. Wavelets are remarkable tools that can stretch and move like an amoeba to find the hidden “events” and then simultaneously give you their location, frequency, and shape. Wavelet Transforms allow this and many other capabilities not possible with conventional methods like the FFT.
This course is vastly different from traditional math-oriented Wavelet courses or books in that we use examples, figures, and computer demonstrations to show how to understand and work with Wavelets. This is a comprehensive, in-depth, up-to-date treatment of the subject, but from an intuitive, conceptual point of view. We do look at a few key equations from the traditional literature but only AFTER the concepts are demonstrated and understood. If desired, further study from scholarly texts and papers is then made much easier and more palatable when you already understand the fundamental equations and how they relate to the real world.
#5 Computational Electromagnetics
This 3-day course teaches the basics of CEM with application examples. Fundamental concepts in the solution of EM radiation and scattering problems are presented. Emphasis is on applying computational methods to practical applications. You will develop a working knowledge of popular methods such as the FEM, MOM, FDTD, FIT, and TLM including asymptotic and hybrid methods. Students will then be able to identify the most relevant CEM method for various applications, avoid common user pitfalls, understand model validation and correctly interpret results. Students are encouraged to bring their laptop to work examples using the provided FEKO Lite code. You will learn the importance of model development and meshing, post- processing for scientific visualization and presentation of results.

Residential Noise Cancellation
Posted by Jim in Analysis and Signal Processing, Underwater Acoustics and Sonar on March 7, 2010
Active cancellation probably won’t work. You need a clearly definable source, a point source preferable. It might be difficult to say where the source is in a house. Also, the cancellation only works on a small area where the listener stays put. That’s why it works in cars, however, you need a noisy car. Lotus cars had a system for cars but in their demo’s they would rent a cheap car. It was a system that plugged into the radio.
The active cancellation head phones work because they only have to cancel at your ear, a small area.
I like masking. It’s low cost and small portable systems are readily available. Otherwise one could purchase an active cancellation head phone but that wouldn’t’ be comfortable to sleep with.
