History of rocket >90s

November 10, 2008

The 1990s brought major changes at JPL. In 1991, Lew Allen retired and Edward C. Stone, the Voyager project scientist, became JPL’s director. The following year, Daniel S. Goldin became NASA administrator. Goldin hated the slow, expensive and not necessarily reliable approach of the past two decades, and set out to reform all of NASA. His favorite targets of ridicule were the failed Mars Observer and a Saturn mission, Cassini/Huygens, which had been recently approved and was expected to cost $3.3 billion. His goal was to reduce the cost of planetary missions all the way down to $150 million. He challenged JPL to adapt itself to his new “faster, better, cheaper” techniques in a 1992 speech.

The result was the most vibrant and exciting period of planetary exploration since the 1960s, and a great deal of pain as Ed Stone and the rest of the lab’s staff tried to find ways to meet Goldin’s challenge. The era ended abruptly in 2000, after JPL lost two more spacecraft, both at Mars.

The Faster, Better, Cheaper Challenge

Goldin, who had been an executive at aerospace giant TRW, thought that by using new management techniques, new technologies and accepting more risk, NASA could dramatically reduce the cost of missions. More could be done without more money.

Doing more with less was important because a major political focus of the Clinton administration was achieving a balanced budget. NASA’s budget shrank 18 percent between 1992 and 1999. Without finding ways to cut costs substantially, JPL faced extinction. The NASA budget would not support enough Cassini-scale missions to keep the lab operating.

In a speech at JPL on May 28, 1992, Goldin laid all this out for JPL’s staff. “We need to stretch ourselves,” he said. “Be bold — take risks. [A] project that’s 20 for 20 isn’t successful. It’s proof that we’re playing it too safe. If the gain is great, risk is warranted. Failure is OK, as long as it’s on a project that’s pushing the frontiers of technology.”

2009 Mercedes-Benz S-Class

November 5, 2008

Introduction
The Mercedes-Benz S-Class is the benchmark for luxury sedans. Completely redesigned just a year ago, the Mercedes S550 and S600 are superb automobiles. The S-Class cabins are among the most beautiful interior executions on the market today. These cars are loaded with technology yet the COMAND system is easier to operate than the systems from BMW and Audi. Underway, the S-Class cars are smooth, quiet, and powerful.

The S-Class is made up of the S550 models, which come with a V8 engine, and the S600, which comes with a turbocharged V12. The S550 4MATIC adds the all-weather capability of all-wheel drive. Two AMG versions bring racecar performance to this big luxury sedan.

Lineup
The 2008 Mercedes-Benz S-Class is composed of the S550 ($86,700), the S550 4MATIC ($89,700), the S600 ($144,200), plus the S63 AMG ($127,000) and the S65 AMG ($144,200). The S550 models are powered by a 5.5-liter V8 and come with a seven-speed automatic transmission; the 4MATIC adds all-wheel drive. The S600 is powered by a 6.0-liter 3-valve V12 twin-turbo engine connected to a heavy-duty five-speed auto. The federal Gas Guzzler Tax adds $1,300 to the V8, $3,000 to the V12. The S63 AMG is powered by a 6.2-liter V8, while the S65 AMG features a 6.0-liter V12.

Walkaround
The current generation S-Class was launched for the 2007 model year. It’s longer, wider and taller than previous models.

The exterior’s most noticeable features are the exaggerated fender flares front and rear. Additional design cues include an upright grille, headlamps and tail lamps, the latter with thick body-colored horizontal bars running through them and tied together with lower body molding. The decklid opening is not contained within the rear fenders, but instead extends out to the side of the body, with a distinctly raised position that looks a bit like the rear end of a 7 Series BMW. That was done for exactly the same aerodynamic reasons as on the BMW, to give the air rushing over the long, long roof panel a good place to separate cleanly from the body without causing drag. A side benefit is a huge trunk opening for easy loading.

Interior
The Mercedes S-Class boasts one of the most beautiful interior executions on the market today. Got Maybach envy? S-Class buyers can order special designo editions with lavish materials that make these truly sumptuous cars.

And it’s relatively easy to learn how to operate. We solved all of the mysteries of a complicated luxury car’s switch layout and control system without looking in the owner’s manual. It’s that easy. The COMAND system, located at the center of the dash, is used to operate the radio, telephone, entertainment system, navigation system, and vehicle systems.

Fashion Technology

introduction

India which has always been a centre for the textile and garment trade is also growing into a centre of innovation in garment and accessory design. Fashion technology has a wide scope for choosing a career. Now the fashion industry has become so specialized that it encompasses a vast field of studies in design, concept management, design production management, quality control, planning, fabric design, printing, fashion accessory design, fashion merchandising, textile science, colour mixing, marketing and so on.

The primary areas of work in the fashion industry are market research, designing and manufacturing of garments and textiles.
Fashion design is the most important area of work in fashion industry. Designing involves creating original designs after studying the changing trends of the market i.e market research. It has various fields of specialisation like garments, footwear, jewellery and even luggage. It is a challenging field as it requires the coordination of various jobs, in small concerns it is usually a one man show but in big organisations the jobs are specialised and allotted to different people.

Manufacturing involves purchasing textiles and fabrics required for the design and making the garment according to the master pattern. Manufacturing process requires employment of a large number of trained personnel.
