On the module of homomorphisms into projective modules and multiplication modules
Periodica Mathematica Hungarica, 1996Let \(A\) and \(B\) be modules over a commutative ring \(R\), and let \(\pi(A,B)\) denote the image of the evaluation map of \(\Hom (A,B) \otimes A\) into \(B\). Let \(T(A)\) denote \(\pi(A,R)\), the trace ideal of \(A\). The authors observe that \(\pi(A,B) =T(A) \cdot B\) whenever \(T(A) \cdot A=A\), in which case \(\pi(A,B)\) is a pure submodule of \(

Communications in Algebra, 1993
C. Menini and A. Orsatti [Rend. Sem. Mat. Univ. Padova 82 (1989), 203--231 (1990); MR1049594 (91h:16026)] introduced ∗-modules in order to characterize equivalences between certain full subcategories of module categories over two rings. If one restricts the study to the case of finite-dimensional algebras over a field k, it was shown by G.

Spatial modulation (SM) is a recently developed transmission technique that uses multiple antennas. The basic idea is to map a block of information bits to two information carrying units: 1) a symbol that was chosen from a constellation diagram and 2) a unique transmit antenna number that was chosen from a set of transmit antennas.

IEEE Transactions on Software Engineering, 1987
Because large-scale software development is a struggle against internal program complexity, the modules into which programs are divided play a central role in software engineering. A module encapsulating a data type allows the programmer to ignore both the details of its operations, and of its value representations.

Formal Methods in System Design, 1999
We present a formal model for concurrent systems. The model represents synchronous and asynchronous components in a uniform framework that supports compositional (assume-guarantee) and hierarchical (stepwise-refinement) design and verification. While synchronous models are based on a notion of atomic computation step, and asynchronous models remove ...

Initially, psychometric functions were measured for the detection of amplitude modulation (AM) or frequency modulation (FM), using a two-alternative forced-choice (2AFC) task. Carrier frequencies were 125, 1000, and 6000 Hz, and modulation rates were 2, 5, and 10 Hz.

ON STRONGLY C2 MODULES AND D2 MODULES
Journal of Algebra and Its Applications, 2013Let R be a ring, MR be a right R-module, n be a positive integer and S = End (MR) be the endomorphism ring of MR. MR is called a strongly C2 module if [Formula: see text] is C2 for every positive integer m. MR is called an n-C2 module if the annihilator rM(K) ≠ 0 for any n-generated proper left ideal K of S. We prove that MR is strongly C2 if and only

Crossed modules and doi-hopf modules
Israel Journal of Mathematics, 1997The main result of this paper is that crossed modules (also known as Yetter-Drinfeld modules) are particular cases of Doi's unified Hopf modules. A generalization of crossed modules is introduced to this end, and a generalization of the Drinfeld double is defined. The latter turns out to be isomorphic to a (generalized) smash product.
