Some Thoughts on DC/DC Converters
Many systems require that the primary source of DC power be converted to other voltages. Battery driven circuitry is an obvious candidate. The 6V or 12V cell in a laptop computer must be converted to different potentials needed for memory, disc drives, display and operating logic. In theory, AC line powered systems should not need DC/DC converters because the implied power transformer can be eq...
متن کاملSome Observations on Dirac Measure-Preserving Transformations and their Results
Dirac measure is an important measure in many related branches to mathematics. The current paper characterizes measure-preserving transformations between two Dirac measure spaces or a Dirac measure space and a probability measure space. Also, it studies isomorphic Dirac measure spaces, equivalence Dirac measure algebras, and conjugate of Dirac measure spaces. The equivalence classes of a Dirac ...
متن کاملSome Observations on "Influenza"
Sir,?I am not attempting in this letter to give any elaborate or comprehensive history of the disease, nor do I consider it necessary to tire my readers by a repetition of its etiology, symptoms or pathological manifestations so ably and voluminously narrated in any good text-book of medicine. I shall only give, in brief, a few features of this disease that came to my notice in the recent epide...
متن کاملSome Observations on Indifferentiability
At Crypto 2005, Coron et al. introduced a formalism to study the presence or absence of structural flaws in iterated hash functions: If one cannot differentiate a hash function using ideal primitives from a random oracle, it is considered structurally sound, while the ability to differentiate it from a random oracle indicates a structural weakness. This model was devised as a tool to see subtle...
متن کاملSome Observations on SHAMATA
In this note we discuss some observation of the SHA-3 candidate SHAMATA [1]. We observe that its internal block cipher is very weak, which could possibly lead to an attack on the hash function.
