Cinematic Architectural Education: A Focus on Fourth SpaceTaher Abdel-Ghani
This talk sheds light on the notion of fourth space as a cinematic methodological tool for architectural design and interpretation. Fourth space deals with the in-between activities and events that socially construct space. Similar to film images, it portrays temporal and spatial narratives that are subjectively constructed by the viewers. Hence, this lecture proposes the adoption of cinema by academics to induce Fourth Space within the architectural products, in other words comprehend and reconstruct reality and spatiality.

SMPS
9. IN SMPS INSTEAD OF MAKING THE
SERIES PASS TRANSISTOR CONDUCTING
CONTINOUSLY A TRANSISTOR IS
OPERATED IN SWITCHING MODE THAT
ACTS AS A RAPIDLY OPENING AND
CLOSING SWITCH. PRACTICALLY WHEN
TRANSISTOR IS OPERATED AS A SWITCH
IT DISSIPATE VERY SMALL POWER
BASIC PRINCIPLE
10. (A)LOW POWER DISSSIPATION
RESULTS I LESS HEATING.
(B)BETTER REGULATION AND
EFFICIENCY.
(C)SMALL IN SIZE AND LOW
COST POWER SUPPLY
ADVANTAGE S OF SMPS
11. IT HAS MAXIMUM ADVANTAGES AS
MENTIONED EARLIER ONLY TWO
INHERENT DISADVANTAGES
( a ) SINCE IT USES SPIKING TECHNIQUE
IT GENERATES ELECTROMAGNETIC
INTERFERENCE (EMI) LIKE NOISE
SPIKES, WHICH MAY AFFECT AUDIO
SECTION OF THE MAIN CIRCUIT
( b ) THE CONTROL PART OF THE CIRCUIT
IS EXPENSIVE,COMPLICATED AND
LESS RELIABLE
DISADVANTAGES OF
SMPS
