All RF Cafe quizzes would make perfect fodder for employment interviews for technicians or engineers - particularly those who are fresh out of school or are relatively new to the work world. Come to think of it, they would make equally excellent study material for the same persons who are going to be interviewed for a job.

Some of these books used in quizzes are available as prizes in the monthly RF Cafe Giveaway.

Note: Many answers contain passages quoted from the text.

RF Cafe Featured Book - Human-Centered Information FusionThis quiz is based on the information presented in Human-Centered Information Fusion, by David L. Hall and John M. Jordan. Published by Artech House.
 Note: Some of these books are available as prizes in the monthly RF Cafe Giveaway.


1.  What is human-centered information fusion?

a)  The inclusion of human sensory data in the processing of situational awareness
     and decision-making

"...traditional data fusions and introduces the changing role of information fusion systems and the emergence of the human user/analyst/observer."  See page 1.



2.  How many model levels are there in the JDL (Joint Director of Laboratories) model?

d)  6

0 = Source refinement, 1 = Object refinement, 2 = Situation refinement, 3 = Threat refinement, 4 = Process refinement, 5 = Cognitive refinement. See page 11.



3. What is a "soft sensor?"

b)  A processor that handles many inputs at once for decision making

Human-centered information fusion incorporates human inputs (human-in-the-loop) as sensory resources in system decision making. See page 24.



4.  What is the "human landscape?"

a)  Environmental (physical and emotional) entities generated by human action and interaction

"For our purposes, the human landscape might be understood as people, in the aggregate at various scales, as they relate to the natural world, the built environment, and each other." See page 37.



5.  What is the term given by the authors to the realm of human sensory input

d)  H-space

The "H" stands for "human." This is different from the H-Space term in topology named in honor of Heinz Hopf. See page 59



6.  Which of these objects serve as sensors for the "Global Neighborhood Watch?"

d)  All the above

"The idea extends the concept of citizens in local neighborhood watch groups seeking to reduce street crime to an international scale for reduction of terrorism." See page 85.



7.  What is data visualization?

c)  Presenting data in non-traditional manner to accentuate important results

Rather than relying on traditional chart types for presenting information, creative methods are employed to highlight information of high importance, and/or minimize irrelevant minor affects. See pages 127 - 146 for examples.



8.  What is sonification?

b)  Using properties of sound as a sensor input

"...way in which a set of data processing operations may be matched with a set of sonic parameters in order to gain insights into the data's dynamics." See page 149.



9.  What does IPB stand for?

a)  Intelligence Preparation of the Battlefield

"Intelligence Preparation of the Battlefield is a systematic, time-tested methodology of analysis for the study and understanding of the effects of battlefield conditions on enemy and friendly forces within a unit's operation and interest area." See page 172.



10.  Where was the term "mega-collaboration" first applied?


b)  To describe comprehensive Internet activity

"The term mega-collaboration appears to have been coined by Neilson to describe activity on the Web in which independent actions from millions of people acting on their own interest collectively create a productive environment." See page 212.
