Driving and the Built Environment: Effects of Compact Development on Motorized Travel, Energy Use, and CO2 Emissions examines the relationship between land development patterns and vehicle miles traveled (VMT) in the United States to assess whether petroleum use, and by extension greenhouse gas (GHG) emissions, could be reduced by changes in the design of development patterns. The report estimates the contributions that changes in residential and mixed-use development patterns and transit investments could make in reducing VMT by 2030 and 20 ....etc

BUILT IN SELF TEST FOR A CMOS ALU

Abstract:- A technique is proposed for implementing BIST (built-in self-test) in a CMOS arithmetic and logic unit (ALU). The approach covers single stuck-open faults and all functional faults that do not induce memory effects. The specific fault set covered by the test includes: (1) all single stuck-open faults on n and p transistors anywhere in the ALU (F1 faults); and (2) all functional faults that affect any single-bit slice of the (F2 faults), a functional fault being any fault that changes one combinati ....etc

The successful explortion of space requires a system that will reliably transport payloads into space and return back to earth; without subjecting them an uncomfortable or hazardous environment. In other words, the space crafts and its pay loads have to be recovered safely into the earth. The space shuttle used at older times were not re-usable. So NASA invented re-usable space shuttle that could launch like a rocket but deliver and land like an aeroplane. Now NASA is planning to launch a series of air-breathing planes that would ....etc

Space shuttles



Previously, all ventures in to space were achieved with giant rockets which, after a certain amount of time , were directed back in to the earth's atmosphere to be reduced to a cinder by the enormous heat of re entry -after the crew and their capsule had been ejected virtually all of that tremendously expensive equipment was destroyed after only one use.

The shuttle, however, to quote to a National Aeronautics And Space Administration officials ,is the first craft to be launched like a rocket, haul like a truck and lan ....etc

ABSTRACT
In its 23 year history, the NASA space shuttle program has seen exhilarating highs and devastating lows. The fleet has taken astronauts on dozens of successful missions, resulting in immeasurable scientific gains. But this success has had a serious cost. In 1986, the challenger exploded during launch procedures, and on February 1st of 2003, the Columbia broke up during re-entry over Texas.
This seminar report would be covering the following points:-
¢ A BRIEF HISTORY OF THE SPACE SHUTTLE.
¢ THE SPACE S ....etc

The Space Shuttle was a manned orbital rocket and spacecraft system operated by NASA on 135 missions from 1981 to 2011. The system combined rocket launch, orbital spacecraft, and re-entry spaceplane with modular add-ons. Major missions included launching numerous satellites and interplanetary probes, conducting space science experiments, and the servicing and construction of space stations. A major international contribution was the Spacelab payload suite, from the ESA.[a ....etc
