Electromagnetic transducers had previously been shown to be capable of acting as pulse to achieve improved range resolution. Compression was achieved using pairs of transducers designed to produce or detect a burst with a linear frequency variation. An alternate approach, which is also easier to fabricate, is to impress a digital phase code on single frequency coils. One such code with good aut...

We introduce in this paper a notion of continuity in digital spaces which extends the usual notion of digital continuity. Our approach uses multivalued maps. We show how the multivalued approach provides a better framework to define topological notions, like retractions, in a far more realistic way than by using just single-valued digitally continuous functions. In particular, we characterize t...

of software radio is the expansion of digital signal processing toward the antenna, and thus to regions where analog signal processing has been dominant so far. It is straightforward to realize that the hardware platform is a most prominent enabling component of a software radio terminal. Of special interest is the very part of the terminal where analog signal processing is replaced by digital ...

Inflammation often plays a key role in the perpetuation of pain. Chronic inflammatory conditions (e.g. osteoarthritis, immune system dysfunction, micro-circulatory disease, painful neuritis, and even heart disease) have increased as baby boomers age. Medicine's current anti-inflammatory choices are NSAIDs and steroids; the value in promoting cure and side effect risks of these medications are u...

This study aimed to compare conventional, digital 2D and 3D workflows as possible aesthetic rehabilitation processes for the maxillary anterior area using “open-source” software. For conventional workflow, a diagnostic wax-up was produced by dental technician. Keynote software (version 11.1) used perform analysis smile planning. Measurements were taken technician obtain wax-up. session, plaster...

Discrete geometry redefines notions borrowed from Euclidean geometry creating a need for new algorithmical tools. The notion of convexity does not translate trivially, and detecting if a discrete region of the plane is convex requires a deeper analysis. To the many different approaches of digital convexity, we propose the combinatorics on words point of view, unnoticed until recently in the pat...

For a finite group $G$‎, ‎let $Cent(G)$ denote the set of centralizers of single elements of $G$‎. ‎In this note we prove that if $|G|leq frac{3}{2}|Cent(G)|$ and $G$ is 2-nilpotent‎, ‎then $Gcong S_3‎, ‎D_{10}$ or $S_3times S_3$‎. ‎This result gives a partial and positive answer to a conjecture raised by A‎. ‎R‎. ‎Ashrafi [On finite groups with a given number of centralizers‎, ‎Algebra‎ ‎Collo...

The moduli used in RSA (see [5]) can be generated by many different sources. The generator of that modulus knows its factorization. They have the ability to forge signatures or break any system based on this moduli. If a moduli and the RSA parameters associated with it were generated by a reputable source, the system would have higher value than if the parameters were generated by an unknown en...
