Troubleshooting Communications Facilities: Measurements and Tests on Data and Telecommunications Circuits, Equipment, and Systems
The first comprehensive guide to troubleshooting communications facilities, it covers all aspects of measurements and tests on data and telecommunications circuits, with emphasis on practical troubleshooting of operating systems. Discusses the different types of tests and measurements and describes network architecture, network components and their most common failure modes. The detailed index permits quick access, making this a handy reference. All information presented conforms to North American and CCITT standards.80% (15)
Weiterstadt, Germany: Camouflaged Porsche 911 Cabriolet prototype crash on Friday 13th, 2009, 2:45am, kills 51-year-old Porsche engineer who was with Porsche for 25 years.
Photo is facing north, the Porsche was traveling south and crashed with the rear into the guardrail, sliding under the guardrail for approx. 50 meters! People who know what damage the edges of a guardrail can do know what happened...! The Porsche didn't break through the median which would have meant that oncoming traffic heading north would have crashed into it.... which would have been even more disastrous since the lights have been torn out by the accident and other vehicles would have crashed into the black and unlighted 911 at a very high rate of speed, after all the left lane is the "fast"-lane, which in Germany means very high speed! The left lane is normally used at an minimum speed of at least 130 km/h (80 mph). At night with little traffic and at that time (2:45am) most people drive much faster when in the fast lane...!!! Weiterstadt, Germany: Camouflaged Porsche 911 Cabriolet prototype crash on Friday 13th, 2009, 2:45am. 51-year-old Porsche engineer who was with Porsche for 25 years did not survive his injuries. A Porsche 911 Cabriolet prototype/test mule (2010/11 model year) crashed into the median guardrail of the southbound A5 (Autobahn 5 Frankfurt-Heidelberg) near Weiterstadt, Germany (see geotag). After spinning around 180 degrees its' tail slid under the guardrail for about 50 meters (150 feet) before coming to a halt. It seems that the steel structure of the guardrail cut of the upper structure (A-Pillar and convertible roof) of the car. This stretch of the A5 has no speed limit. Reasonable high speed driving is allowed! The engineer was driving in tandem with another engineer in a Porsche Panamera which followed shortly behind. The Panamera was able to avoid crashing into the 911 and called police and paramedics. Edit: I seems that both took the on-ramp @ Weiterstadt and that they made a short stop @ the gas station next to the Autobahn. Since the location of the accident and the on/off-ramp is only 700 meters away it's highly unlikely that the porsche was driving very fast! The Porsche 911 was not driving at super high speeds! Porsche conducts high speed testing on closed circuits! Those test mules with new equipment normally don't drive more than 250 km/h (155 mph) and it was wet and snowing very lightly. Every experienced driver would not have driven faster than 140-150 km/h (87-93 mph). My guess is this was a freak accident and the 911 was going around 120-130 km/h (75-80 mph) when he lost control. I hope this will have consequences for the company manufacturing the guardrail, and the state of Hesse maintenance crew installing the guardrail...! This should not have been a fatal accident!!! My deepest condolences to the Porsche engineer's family.Frequency Prescaler 175MHz
Homebrew 175MHz prescaler for frequency counter. This was based on Heathkit IB-102 design, with some modifications. The circuit boards were my only use of a photographic technigue to develop the resist patterns. The boards came out nice but it was too time consuming for a one-off application.
This report was created for global strategic planners who cannot be content with traditional methods of segmenting world markets. With the advent of a "borderless world", cities become a more important criteria in prioritizing markets, as opposed to regions, continents, or countries. This report covers the top 2000 cities in over 200 countries. It does so by reporting the estimated market size (in terms of latent demand) for each major city of the world. It then ranks these cities and reports them in terms of their size as a percent of the country where they are located, their geographic region (e.g. Africa, Asia, Europe, Middle East, North America, Latin America), and the total world market.See also:
In performing various economic analyses for its clients, I have been occasionally asked to investigate the market potential for various products and services across cities. The purpose of the studies is to understand the density of demand within a country and the extent to which a city might be used as a point of distribution within its region. From an economic perspective, however, a city does not represent a population within rigid geographical boundaries. To an economist or strategic planner, a city represents an area of dominant influence over markets in adjacent areas. This influence varies from one industry to another, but also from one period of time to another.
In what follows, I summarize the economic potential for the world's major cities for "test equipment for testing electrical, radio and communication circuits, and motors" for the year 2011. The goal of this report is to report my findings on the real economic potential, or what an economist calls the latent demand, represented by a city when defined as an area of dominant influence. The reader needs to realize that latent demand may or may not represent real sales.
