Enterprise Collaboration: Can You Connect Social Learning and Business Perfor...Human Capital Media
How’s your social learning initiative going? If you are like most companies, you can easily match your situation with one of the following categories.
Category 1: We are just getting started and are unsure of how to proceed.
Category 2: We have started using social media for learning, but we don’t really have a strategy for how to leverage it.
Category 3: We have mastered the technology and its adoption and are seeing daily benefit.
If your situation falls into either Category 1 or Category 2, this session is a must for you. Learn how to put social learning into context and into action in your organization. If your situation is closest to Category 3, we encourage you to attend this session to share the successes of your experience with your peers. Either way, this session promises to connect you.

Digital Signal Processing - Practical Techniques, Tips and Tricks Course SamplerJim Jenkins
The goal of this 3-day course is to Introduce, explain, and demonstrate powerful, proven techniques, tips and “tricks of the trade” that can dramatically improve accuracy, speed and efficiency in Digital Signal Processing (DSP) applications.
The concepts are first presented using many colorful, clear figures along with plain English explanations and real-world examples. They are next demonstrated using clearly written MATLAB programs (with graphics). This way the student sees the key equations “in action” which increases intuitive understanding and learning speed. These (free) working programs can also be later modified or adapted by the student for customized, site specific use.
Each student will receive extensive course slides, a CD with MATLAB m-files for demonstration and later adaptation, supplementary materials and references to aid in the understanding and application of these “techniques, tips, and tricks” and a copy of the instructor’s latest book “The Essential Guide to Digital Signal Processing”.

The fundamental concepts are introduced and illustrated by state-of-the-art examples. This course differs from the typical space systems course in that the technical aspects of each important subsystem are addressed.
AESA Airborne Radar Theory and Operations Technical Training Course SamplerJim Jenkins
The revolutionary active electronically scanned array (AESA) Radar provides huge gains in performance and all the front line fighters in the world from the Americans (F35, F22, F18, F15, F16) to the Europeans, Russians and Chinese already have one or soon will. This four day seminar, which took 10,000 man hours to produce, is a comprehensive treatment on the latest systems engineering technology required to design the modes for an AESA to capitalize on the systems inherent multi role, wide bandwidth, fast beam switching, and high power capabilities. Steve Jobs once said “You must provide the tools to let people become their best”, and this seminar will include two indispensable tools for the AESA engineer. 1) A newly written 400+ page electronic book with interactive calculations and simulations on the more complicated seminar subjects like STAP and Automatic Target Recognition. 2) A professionally designed spread sheet (with software) for designing, capturing and predicting the detection performance of the AESA modes including the challenging Alert-Confirm waveform.
This three day course is intended for practicing systems engineers who want to learn how to apply model-driven systems Successful systems engineering requires a broad understanding of the important principles of modern spacecraft communications.

Both standard bent pipe repeaters and digital processors (on board and ground-based) are studied in depth, and optimized from the standpoint of maximizing throughput and coverage (single footprint and multi-beam). Applications in Fixed Satellite Service (C, X, Ku and Ka bands) and Mobile Satellite Service (L and S bands) are addressed as are the requirements of the associated ground segment for satellite control and the provision of services to end users.
Software Defined Radio Engineering course samplerJim Jenkins
This 3-day course is designed for digital signal processing engineers, RF system engineers, and managers who wish to enhance their understanding of this rapidly emerging technology. Most topics include carefully described design analysis, alternative approaches, performance analysis, and references to published research results. Many topics are illustrated by Matlab simulation demos. An extensive bibliography is included.
Satellite RF Communications and Onboard Processing Course SamplerJim Jenkins
Successful systems engineering requires a broad understanding of the important principles of modern satellite communications and onboard data processing. This course covers both theory and practice, with emphasis on the important system engineering principles, tradeoffs, and rules of thumb. The latest technologies are covered, including those needed for constellations of satellites.
This course is recommended for engineers and scientists interested in acquiring an understanding of satellite communications, command and telemetry, onboard computing, and tracking. Each participant will receive a complete set of notes.

Bioastronautics: Space Exploration and its Effects on the Human Body Course S...Jim Jenkins
This three-day course is intended for technical and managerial personnel who wish to be introduced to the effects of the space environment on humans. This course introduces bioastronautics from a fundamental perspective, assuming no prior knowledge of biology, physiology, or chemistry. The objective of the course is to provide the student with basic knowledge that will allow him or her to contribute more effectively to the human space exploration program. The human body, that through evolution is uniquely designed to function on the Earth, adapts to the space environment characterized by weightlessness and enhanced radiation. These alterations can impact the health and performance of astronauts, especially on return to the Earth.
