The case of a nuclear electromagnetic pulse differs from other kinds of electromagnetic pulse EMP in being a complex electromagnetic multi-pulse. The complex multi-pulse is usually described in terms of three components, and these three components have been defined as such by the international standards commission called the International Electrotechnical Commission IEC.E1 Commercial NG Cut_Yuna Kim 2012
The E1 pulse is the very fast component of nuclear EMP. The E1 component is a very brief but intense electromagnetic field that can quickly induce very high voltages in electrical conductors. The E1 component causes most of its damage by causing electrical breakdown voltages to be exceeded. E1 is the component that can destroy computers and communications equipment; and it changes too fast for ordinary lightning protectors to provide effective protection against it.
Consumer transient protectors are becoming increasingly able to handle faster rise-time pulses, though. There are special transient protectors that are fast enough to suppress nuclear EMP. The E1 component is produced when gamma radiation from the nuclear detonation knocks electrons out of the atoms in the upper atmosphere.
The electrons begin to travel in a generally downward direction at relativistic speeds more than 90 percent of the speed of light. In the absence of a magnetic field, this would produce a large pulse of electric current vertically in the upper atmosphere over the entire affected area. The Earth's magnetic field acts on these electrons to change the direction of electron flow to a right angle to the geomagnetic field.
This interaction of the Earth's magnetic field and the downward electron flow produces a very large, but very brief, electromagnetic pulse over the affected area. Physicist Conrad Longmire has given numerical values for a typical case of the E1 pulse produced by a second generation nuclear weapon such as those used in high altitude tests of Operation Fishbowl in According to Longmire, the typical gamma rays given off by the weapon have an energy of about 2 MEV million electron volts.
When these gamma rays collide with atoms in the mid-stratosphere, the gamma rays knock out electrons. This is known as the Compton effect, and the resulting electrons produce an electric current that is known as the Compton current. The gamma rays transfer about half of their energy to the electrons, so these initial electrons have an energy of about 1 MEV.
This causes the electrons to begin to travel in a generally downward direction at about 94 percent of the speed of light. Relativistic effects cause the mass of these high energy electrons to increase to about 3 times their normal rest mass. If there were no geomagnetic field, and no additional atoms in the lower atmosphere for additional collisions, the electrons would continue to travel downward with an average current density in the stratosphere of about 48 amperes per square meter.
Because of the downward tilt of the Earth's magnetic field at high latitudes, the area of peak field strength is a U-shaped region to the equatorial side of the nuclear detonation. For nuclear detonations over the continental United States, this U-shaped region is south of the detonation point. Near the equator, where the Earth's magnetic field is more nearly horizontal, the E1 field strength is more nearly symmetrical around the burst location.
The Earth's magnetic field quickly deflects the electrons at right angles to the geomagnetic field, and the extent of the deflection depends upon the strength of the magnetic field. At geomagnetic field strengths typical of the central United States, central Europe or Australia, these initial electrons spiral around the magnetic field lines in a circle with a typical radius of about 85 meters about feet.These flexible interface cards support multiple integrated data and voice applications, facilitating the migration from data-only as well as circuit-switched voice services to a packet voice solution.

In addition to the features listed in Table 1, these modules support both T1 and E1, providing additional flexibility for supporting T1, fractional T1, E1, and fractional E1 for both voice and WAN applications simultaneously.
Voice applications can now be clocked independently from data applications, with all ports for voice applications clocked from a single source. The PVDM4 also provides for echo cancellation of up to ms echo-tail length for demanding network conditions. Refer to Table 2 for all configuration options offered with the modules.
An additional onboard PVDM4 is required. Also, each NIM has its own PVDM4, so each module can be connected to a different service provider with no single clock domain restriction.
The ISRs support H. Typically a drop-and-insert multiplexer is used for channelized that is, TDM integration of data and voice onto a single T1, fractional T1, E1, or fractional E1 connection to the central office. You can cross-connect the TDM DS-0 channels with analog voice ports to create an analog cross-connect solution. Table 2.

Overall a very satisfactory short break. We booked a 9 day full circle self drive. Having someone book everything for you was a big help. We were met at the airport by a very helpful driver with a welcome pack and mobile phone. The car rental company picked us up the next morning and then off we went.
Route 1 was easy to drive around and we saw some amazing scenery on our route. Accomodation was basic with shared bathrooms on the package we chose but they can be pgraded to private. We felt the experience to be a very good experience. From the start of our query re: taking a holiday in Scandinavia Irja was very helpful - she was quick to respond to our queries and was always polite and helpful.
Our trip was organised to our expectation and in some cases exceeded our expectationTickets, everything went without a hitch and we were able to find our way around all the countries that we visited and thoroughly enjoyed ourselves. Kolbrun was great and always was very responsive to request or email. I would recommend her service to anyone. Organisation was excellent - saving us the headaches of flight booking, car hire etc. Information pack was comprehensive with interesting suggestions.
Our information pack failed to arrive before we left home (but we were in Norway for a week before our itinerary started). Delighted to find it waiting for us at check in at our Oslo hotel. Any concerns I had were promptly responded to and effectively dealt with by Kolbrun. Delighted with our holiday and by our experiences of Nordic Visitor, and cannot recommend highly enough.
My husband and I went on the 10 day self guided tour of Iceland August 10-19. The books and maps we received help us plan each day and the inss and hostels they picked for us were comfy and perfect. I am an organizer so getting the information sent to us first was great. I had the tour planned but of course when we got there - there were many things to see. The phone they gave us was a big help with dinner reservations.
More than enough mins. When we first arrived we stopped by the office and they went over the map with us and asked us what we wanted to see and then pointed out great items all over the country to stop.
We were able to hit every one of them. I recommend Nordic Visitor to anyone. They are a great help and so organized.Handbook of stochastic analysis and applications. Theory of statistics (Corr.

A statistic (singular) or sample statistic is a single measure of some attribute of a sample (e. A statistic is distinct from a statistical parameter, which is not computable, because often the population is too large to examine and measure all its items.
However, a statistic, when used to estimate a population parameter, is called an estimator. For instance, the sample mean is a statistic that estimates the population mean, which is a parameter. In calculating the arithmetic mean of a sample, for example, the algorithm works by summing all the data values observed in the sample and then dividing this sum by the number of data items.
A statistic is an observable random variable, which differentiates it both from a parameter that is a generally unobservable quantity describing a property of a statistical population, and from an unobservable random variable, such as the difference between an observed measurement and a population average.
Statisticians often contemplate a parameterized family of probability distributions, any member of which could be the distribution of some measurable aspect of each member of a population, from which a sample is drawn randomly. For example, the parameter may be the average height of 25-year-old men in North America.
The average of the heights of all members of the population is not a statistic unless that has somehow also been ascertained (such as by measuring every member of the population).
The average height that would be calculated using all of the individual heights of all 25-year-old North American men is a parameter, and not a statistic. Important potential properties of statistics include completeness, consistency, sufficiency, unbiasedness, minimum mean square error, low variance, robustness, and computational convenience.
Information of a statistic on model parameters can be defined in several ways. The most common is the Fisher information, which is defined on the statistic model induced by the statistic. Kullback information measure can also be used.
