Blurring function

This equation is referred to as the classical imaging equation, from which many iterative algorithms are derived, with a is introduced as the noise-free image. At any point m of coordinates m= x,y, z) in three dimensions, the acquired image for the point is equal to the sum of contributions of the entire observed object 0, weighted by the blurring function h, which is the microscope s PSF. The noise N associated with each point is independent of the image formation system. 

The documentation for the CDPSPEC program suggests typing spec blur from help with the BLUR function. You should instead type cdpspec blur this applies for all CDPSPEC functions. 

Parallel Beam Mode. Let us consider a spherical geometry that completely surrounds the object, and let us assume that all the emitted photons are captured and rearranged into 2-D parallel data sets in Att directions. The PSF of this system is 1/r, and the backprojected blurred function is given by... 

Figure B3.4.8. The correlation fimction c(t) = (ii1q vii(0) as a function of time for photodissociation m a collinear (or tliree-dimensional) polyatomic case. There are tliree relevant time scales T, which measures how rapidly the initial wavefimction dephases T2, which measures how long it takes this mitial wavefimction to regroup and which measures how long the wavefimction takes to Teak to other degrees of freedom. In practice, photodissociation experiments may yield spectra which are more blurred, and/or are not...

Adhesives are used to transfer loads and are typically designed with much higher tensile and shear strengths than sealants. The most important rating of an adhesive ia many appHcatioas is the determiaatioa of how much load it can handle. Some sealants are used as adhesives and some adhesives as sealants and thus arises the occasional blurring of their roles. If the material s primary function is the exclusion of wiad, water, dirt, etc, it is a sealant. 

The ammonia produced by enteric bacteria and absorbed into portal venous blood and the ammonia produced by tissues are rapidly removed from circulation by the liver and converted to urea. Only traces (10—20 Ig/dL) thus normally are present in peripheral blood. This is essential, since ammonia is toxic to the central nervous system. Should portal blood bypass the liver, systemic blood ammonia levels may rise to toxic levels. This occurs in severely impaired hepatic function or the development of collateral links between the portal and systemic veins in cirrhosis. Symptoms of ammonia intoxication include tremor, slurred speech, blurred vision, coma, and ultimately death. Ammonia may be toxic to the brain in part because it reacts with a-ketoglutarate to form glutamate. The resulting depleted levels of a-ketoglutarate then impair function of the tricarboxylic acid (TCA) cycle in neurons. 

Of course, the distinction between reactive- and bound-state wave functions becomes blurred when one considers very long-lived reactive resonances, of the sort considered in Section IV.B, which contain Feynman paths that loop many times around the CL Such a resonance, which will have a very narrow energy width, will behave almost like a bound-state wave function when mapped onto the double space, since e will be almost equal to Fo - The effect of the GP boundary condition would be therefore simply to shift the energies and permitted nodal structures of the resonances, as in a bound-state function. For short-lived resonances, however, Te and To will differ, since they will describe the different decay dynamics produced by the even and odd n Feynman paths separating them will therefore reveal how this dynamics is changed by the GP. The same is true for resonances which are long lived, but which are trapped in a region of space that does not encircle the Cl, so that the decay dynamics involves just a few Feynman loops around the CL... 

Headache and compromised visual function (loss of peripheral vision and blurred vision) caused by the actual tumor mass and its close proximity to the optic structures. 

It has been shown recently, however, that these equations may be solved 62), by means of the state functions theory (64) and/or the time-domain matrix methods 63). Figure 14 shows, for instance, that the computer calculations allow us to determine, with a good approximation, the time-dependence of thermal phenomena taking place in the calorimeter, although all significant details of their kinetics are completely blurred on the thermogram 62). This method has been recently used to correct... 

I went into my classroom the afternoon after they had used the pesticides, and had the most horrendous experience of my life. Talk about visiting hell I had panic attacks for a week, spasms and blurred vision. I couldn t function. I think I was off work for two weeks. 

A genuine rediscovery of the PF should provide the functional dependence of the coefficients of the BP in terms of the molecular properties of the system. This has never been done independently since Gibbs discovery. Therefore, one should make a clear-cut distinction between the phenomenological BP on the one hand and the molecular PF on the other. Unfortunately, the distinction between the two quantities is often blurred in the literature, the two terms sometimes being used as synonyms.
