Conclusion Introduction There are no precise, reliable statistics on the amount of computer crime and the economic loss to victims, partly because many of these crimes are apparently not detected by victims, many of these crimes are never reported to authorities, and partly because the losses are often difficult to calculate. Nevertheless, there is a consensus among both law enforcement personnel and computer scientists who specialize in security that both the number of computer crime incidents and the sophistication of computer criminals is increasing rapidly. Experts in computer security, who are not attorneys, speak of "information warfare".
Same Display Dimensions As a corollary, Equivalent lenses are lenses that produce Equivalent photos on the format they are used on which means they will have the same AOV angle of view and the same aperture diameter. The focal lengths all have the same [diagonal] AOVso we say the focal lengths are equivalent.
The same total amount of light falls on the sensor for the same equivalent relative aperture and same exposure time, so we say the exposures are equivalent. The photos will have the same lightness for the same equivalent exposure and equivalent ISO setting, so we say the ISO settings are equivalent.
An important consequence of the same aperture entrance pupil diameter is that the DOF and diffraction will also be the same for a given perspective, framing, display size, viewing distance, and visual acuity.
In addition, since the exposure times are the same, the same total amount of light will fall on the sensor for all systems with a given scene luminance and lens transmissionwhich means the photos will have the same noise if the sensors are equally efficient.
Of course, sensors are not equally efficient although often, but not always, close Personal exposure essay a given generationnor are all lenses proportionally sharp, have the same color, bokeh, distortion, or flare characteristics, nor do all sensors have the same pixel count, CFA, and AA filter.
Indeed, according to Webster'sthe primary definition of "equivalent" is: Equality of other visual properties, such as noise, detail, etc. The second and third definitions of "equivalent" also fits: On the other hand, sensors of the same generation are usually pretty close in terms of efficiency see here for quite a few examples.
Still, there are other issues to consider, such as color and distortion although these two can usually be corrected for in processingbokeh, lens flare, etc.
So while differences in the technology may well make for differences that matter more than one or more of the parameters of Equivalence, Equivalent photos will typically be the closest in appearance more so, of course, when the sensors are of the same generation.
The larger the photo is displayed, the more extreme the processing, and the lower the amount of light that makes up the photo, the more obvious the role that differences in technology will play. In addition, there is a small niggle in the parameter of "same framing" for systems with different aspect ratios e.
We can either crop one image to the the aspect ratio of the other or crop both to a common aspect ratio or compare at the same AOV and display with the same diagonal measurement. The details of this are discussed at the end of this section.
It is important to note that Equivalent photos on different formats will not have the same exposureand this is the source of most all resistance to the concept.
The reason is quite simple: The same total amount of light will fall on the sensor for Equivalent photos which results in a lower density of light exposure on a larger sensor.
Many feel that exposure has been usurped with DOFbut this reflects not only a lack of understanding of what exposure actually is, but how much of a role DOF plays in a photo, even if DOF, per se, is not a consideration.
While the artistic value of DOF is subjective, the fact is that both the total light falling on the sensor and the DOF are functions of the aperture diameter.
Larger aperture diameters admit more light, but they also introduce more aberrations from the lens.The content of the video on “Child exposure to Domestic Violence” was a personal crime.
First we need to understand what the definition of “personal crime” is: “rape, sexual assault, personal robbery, assault, purse snatching and pocket picking. Cultural Writing. Poetry. Essays. Comprised of footnotes to a non-existent text, THE BODY: AN ESSAY is a meditation on absence, loss and disappearance that offers a guarded "narrative" of what may or may not be a love letter, a dream, a spiritual autobiography, a memoir, a scholarly digression, a treatise on the relation of life to book.
I originally introduced the term “orthorexia” in the article below, published in the October issue of Yoga Journal.

Who Pays Writers notes a rate of about 3 cents per word, but this writer would consider the experience and exposure to be worth the low pay.
Boating enthusiast know that a Carolina Skiff is the most durable, versatile, stable and economical boat on the planet – and we’ve maintained our reputation for more than 30 years. Misperceptions and corrections The recent release of Paul Verhoeven's Starship Troopers has led to a lot of online debate concerning the original book.
Some of the participants have made cogent points based on a thorough understanding of both the book in specific and the military in general.
