Q11.
Which among the following is a scarce resource in terms of cognitive vision systems?

a.

Bus

b.

Memory

c.

Processing hardware

d.

Network

Discuss
Answer: (b).Memory Explanation:Large amount of information has to be stored for learning and articulation of knowledge. It is important to consider memory as a scarce resource and methods must be developed to use it efficiently. Selection of information of interest and data mining are some techniques to use memory efficiently.
Q12.
Which among the following is not a concern for cognition vision system?

a.

RF environment

b.

Characteristics of visual sensory sub-process

c.

High level representational framework

d.

Low level visual sensory sub-process

Discuss
Answer: (a).RF environment Explanation:The construction of cognition vision system involves the selection of appropriate high level representation framework, basic visual sensory sub-process, characteristics of visual sensory sub-process catering to the requirement of desired cognition system, negotiator of control process, and properties of control process.
Q13.
Radio hearing sensors use sound propagation for ____

a.

converting electromagnetic signal into electrical signals

b.

positioning

c.

imaging

d.

navigation

Discuss
Answer: (d).navigation Explanation:Radio hearing sensors convert acoustic signals into electrical signals. Sound propagation is used for navigation, detection, and communication. For example, acoustic location estimation maybe used for cognitive location aware systems.
Q14.
Image sensors are typically passive.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:Image sensors are utilized in a passive manner since they only receive signals. Radio hearing and radio sensors are active sensors since they exhibit both transmission and reception characteristic in wireless systems. Image sensors require direct exposure to the environment whereas radio sensors might operate inside a bag.
Q15.
Data processing algorithms are unique to each category of sensors.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:Sensing is accomplished by sensors and data processing algorithm. Radio sensing, radio vision, and radio hearing have different data processing procedures associated with them. Antenna based positioning systems utilize different algorithm from acoustic based location systems.
Q16.
Which among the following is not feature of location awareness core?

a.

Mobility management

b.

Topographical information

c.

Seamless positioning

d.

Security

Discuss
Answer: (b).Topographical information Explanation:Location sensing is followed by location awareness. Location awareness means to be aware of the location. The results of location awareness are transferred to cognition engine. Seamless positioning and interoperability, security and privacy, statistical learning and tracking, and mobility management are features of location awareness core.
Q17.
European SPACE project uses ____

a.

radio hearing method

b.

environment imaging method

c.

waveform based method

d.

environment sensing based method

Discuss
Answer: (c).waveform based method Explanation:Seamless positioning may be achieved by waveform based method. This approach requires knowledge on all type of existing and future waveforms of current and future systems. European SPACE project is an example of this method and offers centimeter level positioning accuracy.
Q18.
In European SPACE project, the ____ approach helps to support future waveforms.

a.

vendor libraries

b.

plug and play

c.

programming

d.

pre-defined libraries

Discuss
Answer: (b).plug and play Explanation:The SPACE prototype consists of sensors, algorithms, and existing waveforms. The most appropriate positioning mechanism is selected based on user requirement and environment. The prototype has plug and play property which enables easy integration of future waveforms and positioning techniques.
Q19.
RSS based location estimation algorithm is an example of ____

a.

traffic based method

b.

waveform based method

c.

environment sensing based method

d.

source based method

Discuss
Answer: (c).environment sensing based method Explanation:Environment sensing based method may be used for seamless positioning. It monitors channel parameters and changes the algorithm accordingly. In RSS location based algorithm, location of device and path loss coefficient of channel environment are used to maintain accuracy.
Q20.
Environment based method has ____ waveform based method.

a.

higher complexity than

b.

lower complexity than

c.

equal complexity as

d.

equal time duration as

Discuss
Answer: (b).lower complexity than Explanation:Seamless positioning involves maintenance of position accuracy regardless of changes in channel environment. Waveform based approach and environment sensing based approach are the two techniques employed to achieve seamless positioning. Waveform based approach requires large database of all existing and future waveform and hence is more complex than environment sensing based method.
