Long Time, No See: How to Keep Work At-Home Agents Connected

The books in the series have been designed for both independent and tutor assisted studies. For this reason they should prove particularly useful to the “self-starter” and to those wishing to update or upgrade their aircraft maintenance licence. Also, the series should prove a useful source of reference for those taking ab initiotraining programmes in JAR 147 (now ECAR Part-147) and FAR 147 approved organizations and those on related aeronautical engineering programmes in further and higher education establishments.

This book has primarily been written as one in a series of texts, designed to cover the essential knowledge base required by aircraft certifying mechanics, technicians and engineers engaged in engineering maintenance activities on commercial aircraft. In addition, this book should appeal to the members of the armed forces, and students attending training and educational establishments engaged in aircraft engineering maintenance and other related aircraft engineering learning programmes.

In this book we cover in detail the underpinning mathematics, physics, electrical and electronic fundamentals, and aerodynamics necessary to understand the function and operation of the complex technology used in modern aircraft. The book is arranged into four major sections:

1. • Introduction
2. • Scientific fundamentals
3. • Electrical and electronic fundamentals
4. • Fundamentals of aerodynamics

In the Introductory section you will find information on the nature of the aircraft maintenance industry, the types of job role that you can expect, the current methods used to train and educate you for such roles and information on the examinations system directly related to civil aviation maintenance engineering. In addition, you will find information on typical career progression routes, professional recognition, and the legislative framework and safety culture that is so much a part of our industry.

In the section on Scientific fundamentals we start by studying Module 1 of the JAR 66 (now ECAR Part-66) syllabus (see qualifications and levels) covering the elementary mathematics necessary to practice at the category B technician level. It is felt by the authors, that this level of “non-calculator” mathematics is insufficient as a prerequisite to support the study of the physics and the related technology modules, that are to follow. For this reason, and to assist students who wish to pursue other related qualifications, a section has been included on “further mathematics”. The coverage of JAR 66 Module 2 on physics is sufficiently comprehensive and at a depth, necessary for both category B1 and B2 technicians.

The section on Electrical and electronic fundamentals comprehensively covers ECAR 66 Module 3 and ECAR Part-66 Module 4 to a knowledge level suitable for category B2 avionic technicians. Module 5 on Digital Techniques and Electronic Instrument Systems will be covered in the fifth book in the series, Avionic Systems.

This book concludes with a section on the study of Aerodynamics, which has been written to cover ECAR Part-66 Module 8.

In view of the international nature of the civil aviation industry, all aircraft engineering maintenance staff need to be fully conversant with the SI system of units and be able to demonstrate proficiency in manipulating the “English units” of measurement adopted by international aircraft manufacturers, such as the Boeing Aircraft Company. Where considered important, the English units of measure will be emphasized alongside the universally recognized SI system. The chapter on physics (Chapter 4) provides a thorough introduction to SI units, where you will also find mention of the English system, with conversion tables between each system being provided at the beginning of Chapter 4.

To reinforce the subject matter for each major topic, there are numerous worked examples and test your knowledge written questions designed to enhance learning. In addition, at the end of each chapter you will find a selection of multiple-choice questions, that are graded to simulate the depth and breadth of knowledge required by individuals wishing to practice at the mechanic (category A) or technician (category B) level. These multiple choice question papers should be attempted after you have completed your study of the appropriate chapter. In this way, you will obtain a clearer idea of how well you have grasped the subject matter at the module level. Note also that category B knowledge is required by those wishing to practice at the category C or engineer level. Individuals hoping to pursue this route should make sure that they thoroughly understand the relevant information on routes, pathways and examination levels given later.

Further information on matters, such as aerospace operators, aircraft and aircraft component manufacturers, useful web sites, regulatory authorities, training and educational establishments and comprehensive lists of terms, definitions and references, appear as appendices at the end of the book. References are annotated using superscript numbers at the appropriate point in the text.

The real challenge to Lean, however, requires this first change, a shift in the culture. Consumer products manufacturers are early on in their Lean journey compared to companies across industry, with 56% less than a year to 3 years into it. By leveraging external expertise and taking small steps in their Lean programs, these manufacturers are setting their sights on reducing cost, driving down inventory, and sustaining a culture of Lean throughout the enterprise. But success is being found by those Best in Class consumer products manufacturers that go the next step by tying their Lean objectives into business opportunities, and by measuring the impact of the Lean program. These companies are placing more emphasis on monitoring the metrics that are tied with success, including inventory and on-time delivery, to truly maximize the competitive advantage to be responsive to the customer.

2009 Siemens Competition Regional Winners Announced at The University of Texas at Austin; Will Move on to National Finals for Chance at $100,000 Peter Hu Wins Top Individual Prize; Sean Karson, Dan Liu and Kevin Chen Win Top Team Prize.

Research projects in the areas of materials science and mathematics scored top marks this evening, as Peter Hu of Denton, Texas and the team of Sean Karson of Winter Park, Florida, Dan Liu of Austin, Texas and Kevin Chen of Missouri City, Texas received the highest honors at the Region Two Finals of the 2009 Siemens Competition in Math, Science & Technology, the nation’s premier high school science competition.

Tonight’s winners will receive thousands of dollars in college scholarships and be invited to compete at the National Finals in New York City on December 3-7, where the winners of six regional competitions across the United States will vie for scholarships ranging from $10,000 to the top prize of $100,000. The Siemens Competition, a signature program of the Siemens Foundation, is administered by the College Board.

“These students have just earned their place among the nation’s greatest high school scientists,” said James Whaley, President of the Siemens Foundation, based in Iselin, New Jersey. “Each year, the students’ work becomes more impressive, and in a record-setting year such as this one, their achievements become even more outstanding. We are proud to welcome them into our family of Siemens Scholars and look forward to their participation at the national finals in New York City.”

The students presented their research this weekend to a panel of judges from The University of Texas at Austin, host of the Siemens Competition Region Two Finals.

Individual Winner

Peter Hu, a senior at the Texas Academy of Mathematics and Science in Denton, Texas, won the individual category and a $3,000 college scholarship for his materials science project that aimed to develop a novel and biologically compatible material for protein drug delivery. While similar delivery systems for therapeutic proteins are known in scientific literature, many of these materials were found to be carcinogenic. Mr. Hu’s research, titled Novel Thermogelling Dispersions of Polymer Nanoparticles for Controlled Drug Delivery, focused on an alternative FDA-approved material to mimic the behavior of these previous delivery systems, effectively avoiding prior toxicity issues.

“While all of the projects were very impressive today, Mr. Hu’s research was successful on many levels,” said Dr. Christopher Bielawski, Associate Professor in the Department of Chemistry and Biochemistry at The University of Texas at Austin. “This research project established a key proof of concept in the laboratory and the materials presented are poised for examination in living systems. Mr. Hu’s work is very advanced and comparable to that of a second or third year graduate student; with minimal tweaks, this research project stands an excellent chance at being published in a top-tier scientific journal and will likely make quite a splash in many scientific communities.”

Mr. Hu is a senior who aspires to one day lead a research team at a university or facility, such as the National Cancer Institute. Currently, he is the Vice President of the Junior Engineering Technical Society, and is organizing a science demonstration team in order to promote interest in math and science among elementary and middle school students. Mr. Hu is also a member of his school’s Research Organization.

Both of Mr. Hu’s parents are physicists, spurring his interest in science at a young age. In addition to his academic pursuits, Mr. Hu plays piano and violin, as well as basketball and table tennis in his free time. His mentor for this research project was Professor Liping Tang of the Department of Bioengineering at The University of Texas at Arlington.

Team Winners

Sean Karson, a senior at Trinity Prepatory High School in Winter Park, Florida; Dan Liu, a junior at the Liberal Arts and Science Academy High School in Austin, Texas; and Kevin Chen, a junior at William P. Clements High School in Sugar Land, Texas, won the team category and will share a $6,000 college scholarship for their mathematics project entitled Relating Missing and Decycling Edges in Directed Graphs. The team’s mathematics project has the potential to increase efficiency in real world networks by establishing an upper bound on the minimum number of connections that must be removed to destroy all cyclic pathways in systems like the World Wide Web and transcontinental trade routes.

“The team’s work was truly impressive in that it focused on a topic in pure mathematics,” said Dr. Haskell Rosenthal, John T. Stuart III Centennial Professor Emeritus in Mathematics at The University of Texas at Austin. “With new and delicate techniques, they have advanced the infrastructure and knowledge of graph theory by providing better bounds, which is of fundamental importance to the mathematics community. Their depth of knowledge was remarkable, and their work was on the same level of that of a Ph.D.”

Mr. Karson is a senior who has received Excellence Awards for Honors Computer Programming C++, Graphics I, Honors Chemistry, Honors Precalculus, AP JAVA and AP Chemistry. He has also received the Rensselaer Polytechnic Institute Math & Science Award, and is recognized as a National Merit Semifinalist. Mr. Karson is Captain of the Quiz Bowl Team, President of Mu Alpha Theta, a member of the Spanish Honor Society and the National Honor Society and volunteers for the Center of Math, Arts and Science Achievement. He has also received the Varsity Baseball Coach’s Award and the Most Valuable Defensive Player Award, and has been the starting third baseman on the Varsity Baseball Team since his sophomore year. Mr. Karson has also leveraged his love of puzzles to create a club called Rubik’s Revenge, aimed to teach middle school students how to solve Rubik’s Cubes.

Mr. Liu is a junior who aspires to one day become a computer or electronics engineer or programmer. He is currently Vice President of the InvenTeams Club, Co-Director of his school’s Math Team, and a member of the Liberal Arts and Science Academy’s (LASA) National Honor Society Chapter. Mr. Liu is also a part of the LASA Camerata Orchestra and Science Olympiad Team. He is a part of the Circle C Swim Team, and also plays badminton and ping-pong.

Mr. Chen is a junior and is a member of his school’s Mu Alpha Theta, Junior Engineering Technical Society and Computer Science Team.  He is also an active volunteer at a local middle school Math Club. Mr. Chen’s dad is a computer engineer and has taught mathematics and physics in the past, playing a large role in sparking his interest in math when he was young. His mother is also very encouraging and supportive of his passion for math and science, helping to foster his current academic interests.
