12M: SET 1: Write in detail about the pediatric orthosis with a diagram Pediatric orthosis: There are several respects in which a child's orthotic requirements differ from those of an adult and these may extend beyond treatment of the obvious abnormality. Accordingly, before considering specific hardware and research activities, the criteria affecting the performance of an orthosis will be discussed. A child is a particularly dynamic person in terms both of his activity and of his developing personality.  It is important that there is a full appreciation of these factors so that prescription of an orthosis can be made sympathetically and in harmony with his development Human factors: Many physical and emotional factors can affect the success of an orthosis Physical factors can be considered under the headings of deformity, growth and activity Deformity:  Frequently an orthosis is fitted to prevent the development of a deformity, particularly during periods of rapid growth For ...

  12M: Explain the types of intelligent agents. Agent: An agent is anything is anything that can be viewed as perceiving its environment through sensors and acting upon the environment through actuators Agent Program: Agent’s behavior is mathematically described by an agent function Agent’s behavior is practically described by an agent program It is the real implementation AI designs the agent program To design an agent program, we need to understand Percepts Actions Goals Environment  Types: Simple reflex agents Model based reflex agents Goal based agents Utility based agents Simple reflex agents: Uses just condition action rules Works only if the environment is fully observable Model based reflex agents: For the world that is partially observable The agent has to keep track of an internal state that depends on the percept history Goal based agents: Current state of the environment is always not enough The goal is to achieve correctness Utility based agents: Goals alone are n...

12M: 2) 2NF and 3NF with examples Second Normal Form (2NF): For a table to be in the Second Normal Form, It should be in the first normal form It should not have partial dependency 1 column primary key (Basically no 2 rows have the same primary keys) Example: Here the course code is unique and can be taken as primary key SUBJECT NAME COURSE CODE DBMS CS101 CD CS152 AI CS154 Storing student enrollment in various courses. Here, both the columns are not unique, but the tuple (student name, course code) is unique since a student cannot enroll in the same course more than once). But this is not the second normal form. STUDENT NAME COURSE CODE A CS152 B CS101 A CS154 C CS101 To convert to 2NF, we need to break it into 2 tables. In the first table, the second column is unique and we can attach each of these with the course codes in the second table STUDENT NAME ENROLLMENT NUMBER A 1 B 2 C 3 COURSE CODE ENROLLMENT NUMBER CS101 2 CS101 3 CS152 1 CS154 1 These 2 tables together provide u...
