we investigate some properties of approximately quasi inner generalized dynamics and quasi approximately inner generalized derivations on modules. in particular, we prove that if a is a c*-algebra, is the generator of a generalized dynamics on an a-bimodule m satisfying and there exist two sequences of self adjoint elements in a such that for all in a core for , , then is approximately quasi in...

In this paper, we propose a new synchronous stream cipher called SSCQF whose secret-key is   N 1,...z z  S K where i z is a positive integer. Let N d d d ,..., , 2 1 be N positive integers in   1 2 ,..., 1 , 0  m such that i i z d  mod m 2 with m and 8  m . Our purpose is to combine a linear feedback shift registers LFSRs, the arithmetic of quadratic fields: more precisely the unit gro...

We introduce the stripmap mode test of X-band AutoSAR (automobile synthetic aperture radar) prototype in this paper. We design and develop a power amplifier, a signal demodulator, and use Matlab for post-processing. The transmitter of this prototype, however composes measurement instruments, an Arbitrary Waveform Generator (N8241A, Keysight) for chirp generation and a Vector Signal Generator (E...

The Wave Erection Marx Generator is proving to be an excellent high voltage source for the direct generation of RF energy. Unfortunately, effectively radiating the impulse energy is challenging, both in efficiency and high voltage-holdoff capability. Successful efforts have been made to generate RF energy in both the Narrow Band and Ultra Wideband realm, with field strengths in excess of 1 kV/m...

This paper studies two stochastic bulk arrival and bulk service queueing Models (A) and (B) with k varying environments. The system has infinite storing capacity and the arrival and service sizes are finite valued random variables. Matrix partitioning method is used to study the models. In Model (A) the maximum of the arrival sizes in all environments is greater than the maximum of the service ...

We construct a pseudorandom generator which uses O(log m + log d + log 3=2 1==) bits and approximates the volume of any combinatorial rectangle in f1; : : : ; mg d to within error. O(log m + log d + log 2 1==) bits. For a subclass of rectangles with at most t log 1== nontriv-ial dimensions and each dimension being an interval, we also give a pseudorandom generator using O(log log d + log 1== lo...

We show that the families (k, r)–RBC of languages accepted (in quasi-realtime) by one-way counter automata having k blind counters of which r are reversalbounded form a strict and linear hierarchy of semi-AFLs. This hierarchy comprises the families BLIND = M∩(C1) of blind multicounter languages with generator C1 := {w ∈ {a1, b1} ∗ | |w|a1 = |w|b1} and RBC = M∩(B1) of reversal-bounded multicount...

Cryan and Miltersen [7] recently considered the question of whether there can be a pseudorandom generator in NC, that is, a pseudorandom generator that maps n bits strings to m bits strings and such that every bit of the output depends on a constant number k of bits of the seed. They show that for k = 3, if m ≥ 4n + 1, there is a distinguisher; in fact,they show that in this case it is possible...

1.1. Strictly Cyclic Modules and Modular Right Ideals. For a ring A with identity, cyclic modules are precisely those of the form a\A where a is a right ideal. What might be a useful analogous statement for a ring without identity? This question motivates what follows in this subsection. A module M is strictly cyclic if there exists m in M such that mA = M (such an m is called a generator); a r...
