Rating 3.4 stars (7) A sudden ionospheric disturbance (SID) is an abnormally high plasma density in the ionosphere caused by an occasional sudden solar flare, which often interrupts or interferes with telecommunications systems The SID results in a sudden increase in radiowave absorption that is most severe in the upper medium-frequency (MF) and lower high-frequency (HF) ranges When a solar flare occurs on the Sun, a blast of ultraviolet and X-ray radiation hits the day-side of the Earth after 8 minutes This high energy radiation is absorbed by atmospheric particles raising them to excited states and knocking electrons free in the process of photo-ionization The low altitude ionospheric layers (D region and E region) immediately increase in density over the entire day-side The Earth s ionosphere reacts to the intense X-ray and ultraviolet radiation released during a solar flare and often produces shortwave radio fadeout on the day-side of the Earth as the result of enhanced X-rays from a solar flare Shortwave radio waves (in the HF range) are absorbed by the increased particles in the low altitude ionosphere causing a complete blackout of radio communications This is called a Short Wave Fadeout These fadeouts last for a few minutes to a few hours and are most severe in the equatorial regions where the Sun is most directly overhead The ionospheric disturbance enhances long wave (VLF) radio propagation SIDs are observed and recorded by monitoring the signal strength of a distant VLF transmitter As the fadeouts occur, reception of the station strength varies thus creating a fluctuating voltage output at the receiver which can be recorded and observed using a computer with a chart recorder program You can build and investigate the phenomena of SIDs with a special receiver and a low cost data-logger setup You can not only observe when solar flares are occurring but you can collect and analyze the data and display it on your computer The SIDs receiver is a great opportunity to observe firsthand when a solar event occurs, but you can use it to predict when radio blackouts will affect radio propagation, which is extremely useful for amateur radio operators. create thumbnail from pdf c#: Generate a pdf thumbnail (open source/free) - Stack Overflow create pdf thumbnail image c# c# - Create PDF preview - Code Review Stack Exchange

There have been and continue to be international opportunities in VoP/VoMPLS During the recent past, there has been some success in VoP usage in international routes, as shown in Figure 8-5 Figure 8-6 shows the cost savings achievable by VoP technologies in some selected routes, giving VoP a window of opportunity while the arbitrage exists In countries where there is competition and therefore the emergence of new carriers, a VoP/VoMPLS opportunity exists As shown in Figure 8-7, the pool of such countries is increasing, although there has recently been a major practical retrenchment in North America Figure 8-8 depicts some background factors that affect an international/European deployment of VoP/VoMPLS9 Figure 8-9 provides a snapshot of Internet usage in various countries However, as noted in Figure 8-3, the growth of VoP is expected to be in the telephone-set-to-telephone-set market split pdf using itextsharp c#: I want the code for pdf to image conversion in c# | The ASP.NET Forums c# get thumbnail of pdf Create Thumbnail Image from PDF using Ghostscript - CodeProject

Hi Experts How can i convert jpeg image from 1st page of uploaded pdf by using open source tools like iTextSharp or other tools. Why do VLF signals strengthen at night instead of getting weaker If propagation is basically via the waveguide effect, why doesn t the signal drop DOWN at night when the waveguide disappears with the D layer Is there some kind of reduced absorption at night If so, where is it taking place and why Also, what accounts for the big fluctuations in signal strength at night, apparently more or less at random The strength of the received signal depends on the effective reflection coefficient of the region from which the radio wave reflects in its multi-hop path between Earth and the ionosphere In daytime the reflecting region is lower, the air density is higher, and the free electron density is controlled strongly by the solar radiation, etc At night time the reflecting region is higher, the air density is lower, and the free electron density is controlled by variable ambient conditions as well as variable influences from electron precipitation from above, etc At noon the electron density is about 10 electrons/cm3 at an altitude of 40 km, 100 electrons/cm3 at an altitude of 60 km, 1000 electrons/cm3 at an altitude of 80 km and 10,000 electrons/cm3 at an altitude of 85 km At night these figures become 10 electrons electrons/cm3 at 85 km, 100 electrons/cm3 at 88 km and 1000 electrons/cm3 at 95 km and then remains somewhat the same up to at least 140 km At night the electron density in the lower part of the D region pretty much disappears At 40 km the electron collision frequency is about 1,000,000,000 collisions per second whereas at 80 km the collision frequency drops to 1,000,000 collision per second The reflection coefficient depends on (among other things) the number density of free electrons, the collision frequency, and the frequency of the radio signal It is found by a mathematical integration throughout the entire D-region and of course the result depends on what time of the 24 hour day one performs the integration We can think of the E-Layer propagating the signal at night Then the prominent sunrise pattern we see is a shift from E-Layer propagation back to D-Layer as the sun rises and forms the daytime D-Layer. how to create a thumbnail image of a pdf in c# Generate a pdf thumbnail (open source/free) - Stack Overflow
